I've tried every budget method. Spreadsheets with 14 tabs. Apps with color-coded categories. The envelope system with actual envelopes. They all worked for about two weeks. Then I stopped because maintaining the system took longer than the system saved me.
So I built something simpler. A one-page budget. One sheet. One view. Everything you need to see where your money goes each month. The formulas do the math. You just enter numbers.
We've used it for 18 months. It takes about 20 minutes to set up and 10 minutes a month to update. Here's how it works.

Why most budgets fail
Too many categories. Most budget templates have 30-40 line items. "Pet grooming." "Professional development." "Subscriptions - entertainment." Nobody tracks 40 categories. You track 3 for a week and then the spreadsheet becomes another tab you never open.
Our template has 10 categories. That's it. Because 80% of family spending falls into about 8 categories Source: Consumer Expenditure Survey, BLS 2024 . Housing. Food. Transportation. Insurance. Kids. Utilities. Subscriptions. Everything else. If you track those, you track your money. The rest is noise.
How the template works
Column A: The category
Ten rows. Housing (rent/mortgage + insurance + property tax). Groceries. Eating out. Transportation (car payment + gas + insurance). Utilities. Kids (daycare, activities, gear). Subscriptions (streaming, apps, memberships). Insurance (health, life, etc). Savings (emergency fund, 529, retirement). Everything else.
That last row is the secret. "Everything else" catches Target runs, Amazon impulse buys, clothes, gifts, and all the random spending that doesn't fit neatly into a category. You don't need to know that you spent $47.23 at HomeGoods. You need to know that "everything else" was $600 this month and that's $200 more than usual.
Column B: Your budget
What you plan to spend. Fill this in once. Adjust quarterly or when something changes (new daycare, paid off a car, etc). Don't make this aspirational. Make it realistic. If you spend $800/month on groceries, don't put $500 here and feel bad every month. Put $800 and work on bringing it down over time.
Column C: What you actually spent
Update this at the end of each month. Pull the numbers from your bank statement or your budgeting app. Takes about 10 minutes.
Column D: The difference
A formula. Budget minus actual. Green if you're under. Red if you're over. This column is the whole point. You see the gaps at a glance without doing any math.
The summary row
Income minus total spending. That number is your monthly surplus (or deficit). Positive = you have money left to save or invest. Negative = you're spending more than you make and something needs to change.
How to use it with your partner
Share the Google Sheet with your partner. Both of you can see it anytime. Use it as the centerpiece of your monthly money check-in. Open the sheet. Look at column D. Talk about the red rows. Pick one thing to adjust. Done.
The power of one page is that both people see the same picture. No "I didn't know we spent that much." No "I thought we had more saved." One page. One truth. Fewer arguments.
The categories most people forget
Annual expenses divided by 12. Car registration. Amazon Prime. Insurance premiums paid annually. Holiday gifts. Back-to-school. These hit like a surprise every time because you didn't budget monthly for them. Take your annual total, divide by 12, and put that amount in savings every month. When the bill comes, the money is there.
The "just for me" line. Both partners get a number. $50, $100, $200, whatever you can afford. That money is yours to spend on anything without explaining it. Coffee. Video games. Books. A $45 candle that makes you happy. This prevents every small purchase from becoming a discussion and gives both people breathing room inside the budget.
Advanced: the pivot table version
Once you've used the one-page budget for 3-4 months, you'll have data. That data becomes powerful when you pivot it. See our guide: How Pivot Tables Can Change Your Life. You can see spending trends by month, find the categories that creep up over time, and spot seasonal patterns (December is always brutal, August back-to-school is worse than you think).
But start with one page. Keep it simple. Make it stick. The pivot tables come later.
