Start with a template or a blank sheet

Google Sheets has built-in budget templates you can use as a starting point. Open Google Sheets, click the template gallery icon (the grid of squares), search for "budget", and pick one that matches how you think about money — monthly, by category, or by paycheck. If none fit, start blank: open a new sheet and name it something you'll recognize, like "2025 Budget".

A template saves time on layout, but it also locks you into someone else's categories. If you know you want to track groceries, utilities, and childcare separately, or if you get paid twice a month and want to budget that way, a blank sheet gives you that control. Either way, you're working in the same tool — the difference is just how much setup you do at the start.

Key Takeaways

  • Set up columns for the category name, budgeted amount, actual spending, and the difference between the two, so you can see at a glance where you're over or under.
  • Use a separate row for each spending category that matters to you — rent, groceries, utilities, childcare — rather than lumping everything into "other".
  • Enter your actual spending by hand from bank statements or credit card bills, or link your bank account through a third-party tool if your bank supports it.
  • Update your budget monthly and adjust your categories or amounts based on what you actually spent, not what you thought you would spend.

Set up your column headers and spending categories

In the first row, create columns for what you need to track. Start with: Category (the name of what you're spending on), Budgeted (how much you plan to spend), Actual (how much you really spent), and Difference (budgeted minus actual — a positive number means you spent less, negative means you went over). Add more columns if you need them: a Notes column for one-time expenses, or a column for each month if you want a year-long view on one sheet.

In the rows below, list every spending category that takes money from your paycheck. Common ones are rent or mortgage, utilities, groceries, transportation, childcare, insurance, phone, internet, and personal care. Include a row for savings — treat it like a bill you pay yourself. If a category is small (under 5% of your budget), you can group it into "Other" and track it separately later if it becomes a problem. The point is to see the big picture first, then add detail where it matters.

Enter your budgeted amounts

In the Budgeted column, enter the amount you plan to spend on each category each month. For fixed costs like rent, that number is straightforward — it's the same every month. For variable costs like groceries or utilities, look at your last three months of bank statements, add them up, and divide by three. That gives you a realistic average rather than a guess.

If you don't have three months of history, use what you know: if you live somewhere cold, your heating bill will be higher in winter. If you have a new baby, childcare costs might go up. Write down what you think is reasonable, then adjust it in month two or three when you have real numbers. Your first budget is almost always wrong — that's normal and expected.

Record your actual spending

Every month, fill in the Actual column with what you really spent. The easiest way is to log into your bank and credit card accounts, look at transactions for the month, and sort them by category. Write down the total for each category in your sheet. This takes 15 to 30 minutes depending on how many accounts you have and how messy your spending is.

If you have a lot of accounts or hate doing this by hand, you can connect your bank to Google Sheets through a third-party tool. Plaid and Tiller are two services that pull transactions automatically and sort them into categories. Both charge a monthly fee (Tiller is around $10 to $15 a month; Plaid's consumer tools are cheaper or free depending on what you use). For most people, 15 minutes a month of manual entry is faster and cheaper than paying for automation, but if you have five bank accounts or you forget to track spending, automation might be worth it to you.

Use formulas to calculate the difference

In the Difference column, create a formula that subtracts Actual from Budgeted. Click on the first cell in the Difference column (next to your first category's actual spending), type =B2-C2 (where B is your Budgeted column and C is your Actual column), and press Enter. Google Sheets will do the math. A positive number means you spent less than you budgeted; a negative number means you went over.

Copy that formula down to every category row. Click the cell with the formula, then drag the small square at the bottom right corner down to the last row. The formula will adjust automatically for each row. At the bottom of your sheet, add a Total row and sum up all the budgeted amounts, all the actual amounts, and all the differences. That tells you whether you're on track overall.

Review and adjust monthly

At the end of each month, look at your Difference column. Categories with large negative numbers (you spent way more than you budgeted) are where you need to pay attention. Ask yourself: Was that a one-time expense, or is it happening every month? If it's every month, your budget was wrong — adjust the budgeted amount up. If it's one-time (car repair, holiday gift), leave the budget alone and note it in a Notes column so you remember why that month was different.

Categories with large positive numbers (you spent much less) might mean you budgeted too high, or you might have just had a lucky month. Don't cut the budget when ready — wait two or three months to see if it's a pattern. The goal is a budget that's realistic, not one that makes you feel like you're failing because you set the bar too high.

Add a savings goal tracker (optional)

If you want to see whether you're actually saving money, add a row at the bottom called "Remaining" or "Surplus". Create a formula that adds up all your actual spending and subtracts it from your total monthly income. That number is what's left over — money you can put toward savings, debt, or next month's expenses. If it's negative, you're spending more than you earn, and you need to cut something or find more income.

Some people create a separate sheet just for savings goals: how much they want to save for an emergency fund, a car, a vacation, or a down payment. They track progress month by month. This keeps savings visible and makes it feel real, not like an afterthought.

Frequently Asked Questions

Should I use a Google Sheets budget or a budgeting app?

Google Sheets works best if you like to see all your numbers at once and don't mind entering them by hand. Apps like YNAB or Mint pull transactions automatically and send alerts when you're close to a limit. Sheets is free and gives you full control; apps cost money but save time. Start with Sheets — if you find yourself not updating it, try an app.

Can I link my bank account directly to Google Sheets?

Google Sheets doesn't connect to banks on its own. You can use a third-party tool like Plaid or Tiller to pull transactions automatically, but both charge a fee. For most people, logging into your bank once a month and copying numbers into Sheets is faster and cheaper.

What if my income changes month to month?

Use the average of your last three months as your budgeted income, the same way you do for variable expenses. If you're self-employed or work irregular hours, budget conservatively — use the lowest three-month average, not the highest. That way you're never surprised.

How often should I update my budget?

Enter your actual spending once a month, after your bank statement closes. Review the whole budget quarterly (every three months) to see if your categories or amounts need to change. If something major changes — a job loss, a raise, a new baby — update when ready rather than waiting.

Can I use the same sheet for multiple people or accounts?

Yes. Create separate sections for each person or account, or create separate sheets within the same file and name them clearly. If you're budgeting as a couple, decide together what categories matter and who enters the data — one person updating is simpler than two people doing it separately.
