Frequently asked questions

What is the 50/30/20 rule?

It's a budgeting framework that splits after-tax income into 50% needs (rent, groceries, utilities, minimum debt payments), 30% wants (dining out, subscriptions, hobbies), and 20% savings and extra debt payoff. It's meant as a simple starting point, not a strict law.

Should I use gross or take-home pay?

Take-home pay — what actually lands in your account after taxes and deductions. Budgeting from gross income overstates what you have to spend. If your paycheck already deducts retirement savings, you can either add that back and count it in the 20%, or budget the net and treat that saving as separate.

What if 50/30/20 doesn't fit my situation?

Adjust the percentages — the tool lets you. In high-cost areas, needs often exceed 50%, so you might run 60/20/20; if you're paying down debt aggressively or saving for a goal, you might flip toward savings. The exact ratio matters less than consistently spending less than you earn.

About this tool

The budget calculator splits your monthly take-home pay using the 50/30/20 rule: 50% to needs, 30% to wants, 20% to savings and debt payoff. Enter your after-tax income to see the dollar amount for each bucket, with a visual split. The ratios are fully adjustable, because 50/30/20 doesn't fit everyone — high rent can push needs past 50%, and aggressive savers shift more toward savings. It's a simple framework for spending less than you earn and paying yourself first. Everything runs in your browser.
