The 50/30/20 rule splits your take-home pay into needs (rent, food, bills), wants (dining, fun), and savings (or debt payoff). Adjust the percentages to fit your goals.

A simple budget in seconds

The 50/30/20 rule is one of the easiest ways to budget: put 50% of your take-home pay toward needs, 30% toward wants, and 20% toward savings and debt payoff. Enter your monthly income and this calculator shows exactly how many dollars go to each bucket.

Not a fan of the classic split? Adjust the percentages to match your own plan.

What goes in each bucket

  • Needs (50%): rent or mortgage, groceries, utilities, insurance, minimum debt payments, transport.
  • Wants (30%): dining out, streaming, hobbies, travel, shopping.
  • Savings (20%): emergency fund, retirement, investments, and extra debt payoff.

Tips to make it work

  • Use your after-tax (take-home) income, not gross.
  • If your needs exceed 50%, trim wants first, then look for ways to lower fixed costs.
  • Automate the savings portion so it happens before you can spend it.

Frequently asked questions

Is this budget calculator free?

Yes — completely free, no sign-up, and it runs entirely in your browser.

What is the 50/30/20 rule?

A budgeting guideline that allocates 50% of take-home pay to needs, 30% to wants, and 20% to savings and debt repayment.

Should I use gross or net income?

Use your net (after-tax) income — the amount that actually lands in your account — for an accurate budget.

Can I change the percentages?

Yes. The classic split is 50/30/20, but you can set any percentages that total 100% to match your situation.

What if my needs are more than 50%?

That is common in high-cost areas. Reduce the wants bucket first, and look for ways to lower big fixed costs like housing or transport over time.
