Why use a budget spreadsheet?

Visibility into income and expenses

 It lets you see exactly where your money comes in and goes out in one convenient spot.

Flexibility and customization

Plenty of tools exist to help you track expenses and income in a spreadsheet format. Two of the most common options include Microsoft Excel and Google Sheets, both of which let you customize your categories, create formulas, and even turn your numbers into visuals like graphs or charts.

Free or low-cost solution

Thanks to free templates online, you don’t have to start from scratch. You can search for templates within Excel and Google Sheets, or you can create something on design sites like Canva. 

Some people use budgeting spreadsheets alongside savings tools to separate day-to-day spending from longer-term goals.

What you’ll need before you start

Choose your spreadsheet tool (Excel vs. Google Sheets)

Before compiling your numbers, explore both Excel and Google Sheets to see which you like best. 

You can sign up for a free, web-based version of Excel or you can purchase Microsoft365 for download onto your computer. The free version may limit you a bit, especially if you’re into more advanced formulas. And if your internet goes down, you won’t have access to your budget spreadsheet unless you downloaded it to your computer or set it up for offline access. Meanwhile, the paid version gives you more features and access, but there is a fee associated with it and it’s a good idea to create a backup file in case of a computer issue.

Google Sheets is web-based, but it does allow for offline mode to work on your spreadsheet even without an internet connection. It is also free and allows collaboration with other people in real-time — say, a partner or spouse. That can also mean accidental data deletion if two people are working on the same sheet at once. 

If you need more advanced formula options, you’ll want to go with the paid version of Excel. For a basic monthly budget spreadsheet, either Excel or Google Sheets work well.

Once you’ve chosen a tool, using it consistently can help keep your budgeting process simple.

Gather your financial data

Now, you’ll want to gather up your financial data, like your income and your partner’s income. Don’t forget to include any money coming in from a part-time job and any other supplemental income, too. 

You’ll also need to gather information on fixed and variable expenses. Fixed expense categories are recurring expenses and might include rent or mortgage, car loan, student loan, gas and transportation, or insurance. Variable expense categories can include must-haves like household supplies and groceries, but you could also budget for things you enjoy, like going out to eat.

Finally, include any savings goals you have in your expense category. That might be contributing to your retirement account, or perhaps it’s saving up for a wedding or other big event.

Decide your budget period & structure: monthly? weekly? annual?

Creating a monthly budget spreadsheet is pretty common, but it’s not the only option.  You can track your budget on a weekly, monthly, or annual basis, depending on what makes sense for your finances.

Step-by-step: create your budget spreadsheet

  1. Set up your workbook & sheets: Create a new spreadsheet and set it up according to your chosen timeframe. For instance, if you’re going with a monthly option, you may want to create a new sheet or tab within your workbook for each of the 12 months of the year. 
  2. List your income sources: Enter all of your income sources under your income category, including your own, your partner’s, and any money from running a business. 
  3. List your expense categories: List the fixed and variable expense categories you identified earlier, like rent, gas, savings goals, and groceries.
  4. Add budgeted and actual columns: Enter your projected budget numbers for each category, then create a column so you can record what you actually spent each month. This lets you see at a glance if your projected budget was accurate or if it needs some tweaking.
  5. Use formulas to automate totals: Auto-sum is a handy formula to add numbers in a row or column. Try it out to automatically calculate a running total of income and expenses, for example.
  6. Add visuals & conditional formatting: Use conditional formatting so your spreadsheet columns turn a bright color in any areas where you’ve gone over (or under!) budget. It’s a quick way to flag anything out of range. You can also create a pie chart to quickly see which categories you’re spending the most money on. 
  7. Review, update & maintain your budget: Whether you’ve chosen weekly or monthly budgeting, be sure to regularly update your numbers and keep on top of how your budget is doing.

Tips to make your spreadsheet work for you

  • Keep it simple at first to avoid overwhelm — you can always add more data or formulas later.
  • Create categories that match your financial habits.

  • Update weekly or monthly.

  • Adjust categories or your budget as needed.

  • Use formulas and templates to streamline and automate when possible.

  • Back up your spreadsheet in case of technology issues.

  • Lock formulas to avoid accidental changes.

  • Use actual income and expenses, not hypothetical numbers.

Common mistakes to avoid

  • Forgetting to include all income sources.
  • Underestimating variable expenses, like groceries or household needs.

  • Neglecting to review your budget once you set it up.

  • Not customizing templates for your needs.

  • Not including both “Actual” and “Budget” columns for the most useful insights.

Bottom line

Creating a budget spreadsheet doesn’t have to be complicated or expensive, thanks to plenty of software options and templates. Explore what tool works best for you, gather your financial info, and choose how often you’ll track your budget. Then check in and update your spreadsheet regularly to stay on track with your financial goals. 

A budgeting spreadsheet is often used alongside savings tools to help distinguish between day-to-day spending and longer-term financial priorities.

Frequently asked questions

If you’re using a weekly budget spreadsheet, update it at least weekly. Similarly, update a monthly spreadsheet at least once a month.

Budget spreadsheets are especially helpful if you have irregular income because they let you track any patterns or dips and plan around them.

Occasional overspending happens for many people. If it becomes a pattern, adjusting categories or totals may help keep the budget realistic. If it keeps happening, you may want to adjust your budget. For instance, you might increase your budget in the category you’ve overspent by decreasing the budget for a different category.

You can choose to lock the entire spreadsheet with a password or just lock a few cells to keep from changing information by accident.
