Build a Budget Sheet
Money mysteries — where did it all go? — are solved by one boring spreadsheet. A budget sheet needs only three sections: money in, money out, and what is left. Fifteen minutes a month turns financial fog into a clear picture. Start simple; fancy comes later. Let the Explore panel find patterns, and pivot tables summarize the big lists.

TL;DR / Quick Fix
Quick fix: a budget sheet needs only three sections — money in, money out, and what is left. List income at the top, group expenses by category, and let one subtraction show the truth. Update it monthly in fifteen minutes. Clarity beats complexity; start simple and refine.
Follow these steps
- List your income. At the top, write every income source and amount per month. One section, honest numbers — this is the foundation everything stands on.
- Group your expenses. Below income, list spending grouped by category: housing, food, transport, fun. Categories reveal patterns that a flat list hides.
- Subtract to find the truth. One formula: income minus expenses. Positive is breathing room; negative is the leak you are here to fix.
- Track against reality. Each month, fill in what you actually spent beside the plan. The gap between plan and reality is where the learning lives.
- Review monthly, briefly. Fifteen minutes a month: update numbers, glance at categories, adjust one thing. Consistency beats perfection.
- Refine over time. After a few months, split vague categories and add savings goals. The sheet grows with your understanding.

What NOT to do
- Do not build a monster spreadsheet first. Complexity kills budgets — start with three sections and earn the fancy features.
- Do not guess your spending. Check bank statements for the first month; memory lies about money.
- Do not budget down to the penny. Round numbers you will actually maintain beat precise ones you abandon.
- Do not skip the monthly review. An unreviewed budget is a diary nobody reads — the review is the whole point.
Frequently asked questions
Should I use Excel or Google Sheets?
Either works. Sheets wins for phone access and sharing; Excel wins for power features. Pick the one you will actually open.
How detailed should categories be?
Start broad — five to eight categories. Split them only when a category's vagueness hides a problem.
What if my income varies?
Budget on your lowest typical month and treat extra as bonus. Variable income needs a buffer category, not optimism.
