I have tried every budgeting app. Mint, YNAB, EveryDollar, a notebook, a Google Sheet with 14 tabs and color-coded categories and auto-importing bank feeds. None of them stuck. The apps required too much maintenance. The notebook I forgot to update. The fancy spreadsheet was so complicated I dreaded opening it.

The Problem with Most Budget Systems

They ask too much. They want you to categorize every coffee, every parking meter, every random Venmo split. You spend more time managing the budget than actually changing your spending habits. A budget that takes 30 minutes a day is a budget you will abandon by Thursday.

The 5-Minute System

Here is the spreadsheet that actually worked for me. It has three columns and takes five minutes once a week. That is it.

1. Column A: What came in this week. Paycheck, side gig, gift money, whatever. One number. If nothing came in this week, put zero.
2. Column B: What went out this week. I do not break it into categories. I open my bank app, look at the weekly spending total, and write that single number. Rent and bills that are on autopay get added here too even though I did not manually pay them — they are still spending.
3. Column C: A minus B. If the number is green, I spent less than I earned. If red, I spent more. That is the entire analysis.

Next to that, I have one more column: “One thing I bought this week that I regret.” Just one. No guilt, no judgement. Just noticing. Over time, seeing “late-night Amazon order” show up six weeks in a row made me turn off one-click ordering. That single awareness changed my spending more than any category breakdown ever did.

Why This Works

Detailed budgets trigger something called decision fatigue. Every time you have to decide whether “Starbucks” goes under Food or Entertainment, you burn a tiny bit of mental energy. Do that 20 times in a session and you are exhausted. Exhausted people quit.

The weekly check-in keeps you aware without requiring daily attention. Five minutes every Sunday morning while coffee brews. You see the trend — green week or red week — and adjust accordingly. If you had two red weeks in a row, maybe skip eating out this week. No spreadsheet needed for that decision.

When You Need More Detail

If you have been doing the simple system for a few months and consistently seeing red numbers, then add detail — but only then. Pick your three biggest spending categories (for most people it is housing, food, and transportation) and track just those. Everything else can stay lumped together until a specific category becomes a problem.

I still use this spreadsheet. It is not impressive. It will not go viral on personal finance TikTok. But it is the first system I have actually kept using, and that is the only thing that matters.
