Building a Simple Budget That Sticks
Budgets get a bad reputation for being restrictive and complicated. But a budget is really just a plan for your money — and a simple one that you actually use beats a perfect one you abandon after two weeks. This lesson builds your first working budget from scratch.
What a budget actually is
A budget is a decision made in advance about where your money goes. It's the difference between your money going somewhere by default and going somewhere by choice.
The goal isn't to track every dollar with perfect accuracy. The goal is to have a rough plan that keeps you from being surprised at the end of the month.
Start with what comes in
Before you can plan where money goes, you need to know how much is coming in. Use your net pay — not gross. If your income varies, use your average from the last 2–3 months, or use your lowest typical month as a conservative starting point.
The 50/30/20 framework revisited
We introduced this in Lesson 1. Now that you understand needs, wants, emergency funds, and savings goals, here it is with more context:
Housing, transportation, phone, food essentials, bills
Eating out, entertainment, subscriptions, clothes beyond basics
Emergency fund first, then goals, then eventually investing
These percentages are a starting point, not a law. If you live at home with no rent, your needs percentage will be much lower — meaning more can go to savings.
A one-page budget format
You don't need an app. A notes app or piece of paper works: Monthly net income, minus fixed needs (phone, bus pass), minus variable needs (groceries — estimate), minus savings target, equals what's left for wants.
If 'wants' comes out negative, one of the other categories needs to shrink. If it comes out to more than 30% of income, consider increasing savings.
At month end you have $40 left in your wants budget but want to buy a $60 item. What's the best next step?
