How to Calculate Your Monthly Expenses (Without a Complicated Budget)

If you’ve ever tried to make a budget and immediately felt overwhelmed, discouraged, or like you were failing before you even started… you’re not alone.

For a long time, I thought budgeting had to mean tracking every dollar perfectly, creating complicated spreadsheets, and constantly adjusting numbers that never seemed to reflect real life anyway. And honestly? As a wife, mom, homeowner, and someone trying to manage a busy, sometimes chaotic season of life, that kind of budgeting just wasn’t sustainable for me.

That’s part of why I created the Simply Balanced System.

Instead of starting with strict rules and unrealistic expectations, we’re starting with awareness. Before we worry about cutting every expense or building the “perfect” budget, we first need to understand what our lives actually cost right now.

In the last step of this series, we set up the foundation by separating bills and spending into two different checking accounts. If you missed that post, you can go back and read: How to Organize Your Finances With Two Bank Accounts.

Today, we’re going to calculate your monthly expenses layer by layer in a way that feels realistic, practical, and manageable.

This is not about shame.
It’s not about perfection.
And it’s definitely not about pretending your life looks like someone else’s.

It’s about creating clarity, reducing financial stress, and building a stronger foundation for your home one step at a time.

Before we start calculating numbers, I want you to remember this throughout the process:

God provides. We steward.

We may not be able to change everything overnight, but we can begin preparing the ground for something healthier, more peaceful, and more sustainable moving forward.

Simply Balanced is my step-by-step approach to organizing your finances in a way that feels realistic, sustainable, and supportive of real life. This isn’t about creating a perfect budget overnight or following rigid rules that leave you feeling exhausted and discouraged.

Instead, we’re building a strong financial foundation one layer at a time.

This post is part of Step 1: Foundation, where we focus on understanding what your life actually costs before trying to change everything all at once.

Right now, we’re specifically working through:

• separating bills from spending
• calculating your true monthly expenses
• and preparing to simplify and automate your finances

There are more steps coming, but the goal is to move through them gradually instead of trying to “fix” your finances in a single weekend.

Instead of trying to fix everything at once, this system walks you through your finances step-by-step so it actually fits into real life.

Right now, we’re focusing on Step 1—because when your foundation is solid, everything else becomes easier.

I think one of the biggest reasons so many people give up on budgeting is because most budgeting systems were never designed for real life.

They assume:

• your income is perfectly consistent
• unexpected expenses never happen
• your children never get sick
• your car never breaks down
• and you always have the time and mental energy to track every dollar perfectly

But for many families, life just doesn’t work that way.

A lot of traditional budgets are also incredibly detailed and rigid. You miss one category, overspend in one area, or forget to track a purchase, and suddenly it feels like the entire system has failed. Over time, that pressure becomes exhausting.

I know for me personally, that’s why I quit budgeting more than once. It felt like I was constantly trying to force my real life into a system that didn’t actually support the season I was living in.

That’s why Simply Balanced is different.

We’re not building a perfect budget—we’re building a system that supports your real life.

A system that creates awareness without obsession.
A system that gives structure without making you feel trapped.
And a system that can grow with your family over time instead of falling apart the moment life gets messy.

Before you can calculate your monthly expenses realistically, you first need a clear picture of what your life actually costs right now.

That means looking honestly at:

• what comes into your home each month
• what your life currently costs
• and where your money is actually going

The Consumer Financial Protection Bureau also recommends understanding your recurring expenses and cash flow before building a financial plan or budget.

But let me say this clearly before we continue:

You do not need exact numbers to the penny.
You do not need to do this perfectly.
And you do not need to have everything figured out today.

Right now, we’re simply creating awareness and building a starting point.

Some of these numbers may surprise you.
Some categories may need adjusting later.
And that’s completely okay.

This isn’t about getting everything perfect the first time.

It’s about finally creating enough clarity that you can begin making intentional decisions moving forward.

Before we start calculating your monthly expenses, it’s important to understand that there are two primary ways money leaves your home:

1. Expenses
2. Spending

And while both matter, they function very differently.

Understanding the difference between the two is what helps the Simply Balanced System work in real life.

Expenses are the recurring obligations your household is responsible for paying each month.

These are the things that usually:

• have due dates
• are somewhat predictable
• are required to maintain your current life and responsibilities

Many of these expenses are either fixed or only fluctuate slightly from month to month.

Examples of expenses include:

• mortgage or rent
• electric bill
• water bill
• insurance
• minimum debt payments
• childcare
• car insurance

These are the bills that need to be planned for consistently because they keep your household functioning.

Spending is different.

Spending is made up of the day-to-day financial decisions you make throughout the month. While some spending categories are necessary, the amount you spend is often more flexible and within your control.

Examples of spending include:

• groceries
• gas
• eating out
• household decor
• clothing
• entertainment
• coffee runs
• personal care purchases

For example:

• your mortgage is an expense
• your groceries are spending

You need both housing and food, but you typically have far more control over:

• where you shop
• what you buy
• how much you spend
• and how often you purchase extras

Another example:

• your electric bill is an expense
• a pedicure is spending

Neither category is automatically “good” or “bad.” The goal is simply understanding the difference so you can organize your finances more intentionally moving forward.

In this step of the Simply Balanced System, we’re primarily focused on your expenses—the bills and obligations your income needs to cover consistently each month.

We’ll go deeper into spending habits and flexible spending categories later in Step 2: Framing.

Before you begin working through the numbers, I want to encourage you to pause for a moment and invite God into this process.

Not because you need to have perfect finances before He cares about you.
And not because organizing your money somehow makes you “more worthy.”

But because stewardship matters.

Everything we have ultimately comes from Him, and learning how to manage it wisely is a part of building a healthy, peaceful home.

One of the core reminders behind the Simply Balanced System is this:

God provides. I steward.

God is the provider.
We are the stewards of what He places in our hands.

That means this process is not just about numbers on a page. It’s about creating awareness, making intentional decisions, and learning how to handle what we’ve been entrusted with faithfully and wisely over time.

As you work through this step, ask God for:

• wisdom
• peace
• discernment
• self-control
• and clarity

If you’d like you can pray something simple like this before you continue:

Some decisions may feel difficult.
Some numbers may feel uncomfortable.
But remember: awareness is not failure.

You are simply preparing the ground for something healthier moving forward.

Before continuing, take a moment to pray and ask God to guide you through this process with peace, wisdom, and grace.

Before we begin calculating your monthly expenses, gather a few things so you can work through this process without constantly stopping and searching for information.

Here’s what you’ll need:

• The last 3 months of bank statements
• Credit Card Statements
• A highlighter
• Pencil or pen
• A notebook or loose paper
• A calculator or calculator app on your phone

You can absolutely do this digitally, but if you tend to feel overwhelmed by tabs, apps, or switching between screens, I personally think printing your statements can make this process feel much simpler and easier to follow.

One important tip:
Try to avoid unusually expensive months if possible.

For example:

• December often includes Christmas spending
• August may include back-to-school shopping
• vacation months can distort your normal spending

Instead, try to choose three fairly average recent months that reflect your normal day-to-day life as closely as possible.

Before you start writing everything out, I want to make this process easier for you.

One of the hardest parts of organizing your finances is staring at a blank page and not knowing where to begin. That’s exactly why I created the Preparing the Ground Workbook to go alongside this step of the Simply Balanced System.

Instead of trying to organize everything from scratch, the workbook walks you through each financial layer step-by-step so you can:

• organize your expenses more clearly
• calculate your monthly totals
• reduce overwhelm
• and stay focused on one category at a time

It’s designed to help you build awareness without feeling buried in spreadsheets or complicated budgeting systems.

Inside the workbook, you’ll find guided pages for:

• income and giving
• home essentials
• household needs
• debt payments
• everyday spending
• and lifestyle choices

As you work through this post, I highly recommend using the workbook alongside it so you can follow the process in real time instead of trying to remember everything later.

You can download the free workbook and join The Balanced Home, where I share additional Simply Balanced resources, encouragement, updates, and future tools designed to help you create a more peaceful and intentional home.

Before we start organizing expenses, we first need to understand what is consistently coming into your household each month.

Using the last 3 months of bank statements, paystubs, or deposit records, write down all regular income sources inside the Provision section of your Preparing the Ground Workbook.

This may involve:

• job income
• child support
• alimony
• social security
• regular side income
• cash income if it is fairly consistent

Right now, we are only focused on income that regularly supports your household. Try not to include one-time money like:

• gifts
• tax refunds
• occasional bonuses
• random reimbursements

The goal is to identify what your normal monthly life is being funded by.

If your income changes from month to month, don’t panic. Many families have irregular income, especially with overtime, commission, side work, self-employment, or seasonal shifts.

Simply total the last 3 months together and divide by three to find your average monthly income.

And remember:
this does not need to be perfect.

If your numbers are close, that’s okay. You can even round to the nearest hundred if needed. We are creating awareness—not trying to build a flawless accounting spreadsheet.

When you calculate your monthly expenses later in this process, your income becomes the foundation everything else is built on.

Once you’ve found your average monthly income, transfer that number to Your Financial Foundation page of the workbook.

This is your starting point.

And if the number feels smaller than you hoped, take a deep breath before moving on. Awareness is not failure. We’re simply identifying where things stand today so we can begin building a stronger financial foundation moving forward.

Before we begin organizing expenses, I want to encourage you to make one intentional decision first: your giving.

In the Simply Balanced System, giving is not treated as “whatever is left over at the end of the month.”
It’s part of the foundation.

Why?

Because giving reminds us that money is not our provider—God is.

One of the core mindset shifts behind this system is:

God provides. I steward.

Everything we have ultimately comes from Him, and giving is one way we practice trust, obedience, gratitude, and stewardship with what He has placed in our hands.

For many Christians, this looks like tithing, which means giving 10% of your income back to God through your local church or ministry. Personally, I believe in tithing from gross income, but I also believe this is something you should pray through personally as you grow in your walk with God.

And if giving consistently feels impossible right now, please don’t read this with shame.

This step is not about perfection.
It’s about intentionality.

If needed, start small and grow over time. The important thing is beginning to approach your finances with a posture of stewardship instead of fear.

Inside the Giving section of your workbook, write down the amount you want to commit to giving moving forward each month.

Then, subtract that amount from your monthly income total on the Your Financial Foundation page.

This number becomes your new starting point moving forward.

And remember: consistency matters far more than performance here. This is not about earning God’s love or proving your worth. It’s about learning to trust Him while becoming a better steward of what you’ve already been given.

Now that you’ve identified your income and committed to your giving, it’s time to begin identifying your actual recurring expenses.

And this is important:
do not rely on memory for this step.

Most of us forget far more recurring expenses than we realize—especially when life feels busy or overwhelming. Small subscriptions, autopays, fluctuating bills, annual renewals, and recurring charges often blend into the background until we intentionally stop and look for them.

That’s why this step matters so much.

Take your last 3 months of statements and slowly review them one page at a time.

As you go through each statement, use one highlighter color to mark ONLY recurring expenses and bills.

Right now, you are looking for things like:

• mortgage or rent payments
• utilities
• insurance
• minimum debt payments
• subscriptions
• memberships
• childcare
• phone bills
• internet
• recurring autopays
• and other regular obligations

Some expenses may fluctuate from month to month, like electric or water bills. That’s completely normal. We’ll average those later.

You may also notice annual subscriptions or charges that only appear once during the three months you’re reviewing. If it’s something you plan to keep long-term, make a quick note so you can mentally divide that cost into a monthly amount later if needed.

And one important reminder:
leave spending unmarked for now.

Do not cross items out or try to analyze every purchase yet. We’ll work through spending habits and flexible spending categories more deeply later in Step 2: Framing.

At this stage, you are NOT:

• judging your spending
• building the perfect budget
• or tracking every dollar perfectly

You are simply identifying:

• recurring obligations
• required expenses
• and the bills your income is currently supporting each month

Take your time with this step.

For many people, this process feels eye-opening. You may discover subscriptions you forgot about, bills you underestimated, or recurring charges that no longer align with your priorities.

That awareness is not failure.

Awareness is what allows change to happen.

If you haven’t downloaded the Preparing the ground Workbook yet, this is the perfect time to grab it.

The workbook walks you through each financial layer step-by-step so you can calculate your monthly expenses without feeling overwhelmed or wondering where to put everything.

Download the workbook below and continue following along as we organize your expenses into layers.

Now that you’ve identified your recurring expenses, it’s time to begin organizing them into layers inside your workbook.

This step helps you understand:

• what your life truly costs
• which expenses are necessary
• and where your money is currently going each month

As you work through this section, remember that the goal is not perfection. You may move expenses around later as you refine things, and that’s okay. Right now, we’re simply creating structure and awareness.

As you organize your bills into layers, it becomes much easier to calculate your monthly expenses accurately without feeling overwhelmed.

Start by filling out the Home Essentials page of your workbook, or a fresh paper labeled as such.

These are the expenses required to keep your household running safely and consistently.

This category may include:

• mortgage or rent
• electric
• water
• natural gas
• homeowners or renters insurance
• property taxes
• required HOA fees
• and other basic housing-related expenses

Think of these as the bills directly tied to maintaining your home and keeping it operational each month.

Next, move into the Household Needs page.

These are the practical costs required for the daily lives of everyone in the household; daily life, work, parenting, and responsibilities.

This category may include:

• transportation costs (not including fuel)
• car insurance
• childcare
• phones
• internet required for work or school
• school-related needs
• and other necessary household responsibilities

These expenses are essential to the way your household currently functions.

Now, list your Minimum Debt Payments.

This may include:

• credit cards
• car loans
• student loans
• personal loans
• home equity loans or line of credit
• and other recurring debt obligations

For now, only include the minimum required monthly payments.

Do not include extra debt payoff amounts yet—even if you’ve been trying to pay extra recently. We’ll focus on debt payoff strategies later in the Simply Balanced System.

Right now, we’re simply identifying what your income is currently required to cover each month.

Finally, estimate your Everyday Spending.

This includes the flexible spending categories that happen throughout normal life, such as:

• groceries
• gas
• household basics
• toiletries
• cleaning supplies
• and other day-to-day purchases

This number does NOT need to be exact right now.

You are not trying to track every dollar perfectly at this stage. Instead, make a realistic estimate based on your recent spending habits and the season of life you’re currently in.

Awareness first. Refinement later.

We’ll go much deeper into spending habits, spending triggers, and realistic spending plans later in Step 2: Framing.

Now that your essential expenses are organized into layers, it’s time to begin calculating your averages and seeing what your basic life currently costs each month.

As you calculate your monthly expenses, remember that these numbers are tools for awareness—not judgment.

Using your workbook, total each category for all 3 months and calculate the average monthly amount for each layer.

Then transfer those totals to the Your Financial Foundation page.

At this stage, your foundation page should include:

• average monthly income
• planned giving
• home essentials
• household needs
• minimum debt payments
• and estimated everyday spending

As you subtract each layer from your income, you’ll begin to see how much money is realistically remaining each month after your core responsibilities are covered.

And one very important reminder:

Do NOT include Lifestyle Choices yet.

Right now, we want to first see:

• what your essential life actually costs
• and how much financial margin truly exists before optional recurring expenses are added back in

This is important because many of us unknowingly build our entire financial life around subscriptions, conveniences, memberships, and recurring extras without first understanding whether our foundation is actually stable underneath them.

This step helps create clarity.

And if the remaining number feels smaller than expected, please don’t spiral emotionally here.

This number is information—not failure.

You are not “bad with money” because your expenses are high.
You are not failing because life costs more than you expected.
And you are not stuck forever where you are today.

Right now, you’re simply uncovering the truth about what your current season of life costs so you can begin making intentional decisions moving forward.

Now that you understand what your core life expenses actually cost, it’s time to evaluate your optional recurring expenses and lifestyle choices.

This category may include things like:

• streaming services
• memberships
• subscription boxes
• gaming subscriptions
• entertainment services
• beauty memberships
• recurring convenience purchases
• and other monthly extras

On the Lifestyle Choices page of your workbook, go through each recurring expenses and decide whether you want to:

• Keep
• Cancel
• or Decide Later

And before we continue, I want to say something important:

This step is not about removing every joyful thing from your life.

You do not need to eliminate every coffee, every convenience, or every form of entertainment in order to make progress financially. The goal here is not punishment—it’s intentionality.

Instead, this step is about asking:

“What matters most in this season?”

Right now, we are building a stronger finanical foundation. And later in the Simply Balanced System, we’ll also be working toward:

• creating a financial buffer in Step 3: Roofing
• planning for irregular expenses and future needs in Step 4: Systems
• and paying down debt more aggressively in Step 5: Finishing Touches

That means the more margin you can free up now, the easier those future steps become.

As you evaluate your lifestyle choices, ask yourself questions like:

• Is this adding real value to our lives right now?
• Would I rather keep this expense or create more financial breathing room?
• Is this worth delaying my progress toward debt freedom or stability?

For some families, certain subscriptions or conveniences may genuinely feel worth keeping in this season.
For others, this may become an opportunity to simplify and reset priorities for a while.

Once you’ve decided what you plan to keep moving forward, total those remaining lifestyle expenses and add them to your Your Financial Foundation page.

Then calculate your true remaining funds after all expenses—including optional ones—have been accounted for.

This final number helps reveal how much room currently exists for:

• savings
• debt payoff
• emergency buffers
• and future financial goals

And remember: this process is not about shame.

It’s about awareness, stewardship, and making intentional decisions one step at a time.

Now comes the part many people avoid:
actually canceling the things you’ve decided to remove.

And I want to encourage you not to put this step off until “later.”

If you already know a subscription, membership, or recurring expense no longer serves your goals or priorities in this season, take a few minutes and cancel it now while it’s fresh on your mind.

One of the reasons financial stress can feel so overwhelming is because many of us have small financial leaks happening constantly in the background:

• subscriptions we forgot about
• autopays we no longer use
• recurring charges we stopped valuing months ago
• convenience expenses that quietly piled up over time

This step is about stopping the financial bleeding before we begin building and strengthening the rest of the system.

And remember:
canceling something today does not mean you can never bring it back later.

This season may simply require a different level of intentionality while you work toward:

• building stability
• reducing stress
• creating margin
• and strengthening your financial foundation

The next step in Simply Balanced is creating systems that simplify and automate the bills you’ve decided to keep so your finances require less mental energy and day-to-day management.

But before we move there, take a little time to clean up what no longer belongs in this season.

Before you move on to the next step, slow down for a moment and reflect on what you’ve discovered throughout this process.

On your Your Financial Foundation page, take a few minutes to answer the reflection questions:

• What surprised you most?
• Where do you feel led to make changes in this season?

This step matters more than it may seem.

Financial change usually doesn’t happen because of one giant dramatic decision. More often, it happens through small intentional choices repeated consistently over time.

And that’s exactly what you’re beginning to build here.

If this process felt emotional, eye-opening, uncomfortable, encouraging, or even overwhelming at times—that’s normal. You are uncovering patterns, responsibilities, habits, and realities that may have been buried under stress or survival mode for a long time.

But clarity creates change.

And progress is far more important than perfection.

You do not have to fix everything today.
You do not need the perfect budget.
And you do not need to have every answer before moving forward.

Right now, you are simply preparing the ground for a stronger financial foundation one intentional step at a time.

Right now, everything you’ve done in this process has been manual.

You gathered the numbers.
You identified the expenses.
You evaluated what stays and what goes.
And you created awareness around what your life truly costs in this season.

That awareness is powerful—but awareness alone doesn’t reduce stress long-term.

The next step in the Simply Balanced System is learning how to simplify and automate the expenses you’ve decided to keep so your finances require less daily thought, less mental energy, and less constant juggling.

Because the goal is not to spend the rest of your life obsessing over money.

The goal is to create systems that support your home quietly in the background while giving you more space to focus on:

• your faith
• your family
• your peace
• and the things that matter most

If you haven’t downloaded the Preparing the Ground Workbook yet, you can grab it below and start working through these steps today.

You do not need to finish everything perfectly in one sitting.

Even one small intentional step today can create real progress over time.
