50/30/20 Budget Calculator

The 50/30/20 rule is the simplest budget there is: split your take-home pay into 50% needs, 30% wants and 20% savings. Enter your monthly income to see the dollar amounts — and adjust the percentages to fit your life. Updates as you type.

How to use it

• Needs (50%) — rent/mortgage, groceries, utilities, transport, insurance, minimum debt payments. The must-pays.
• Wants (30%) — dining out, subscriptions, hobbies, travel, upgrades. The nice-to-haves.
• Savings (20%) — emergency fund, investments, and any extra debt payments beyond the minimum.

Use your after-tax income, and treat the split as a starting point — adjust the percentages if your rent is high or you're saving hard. The goal is awareness and a plan, not perfection.

This is an educational guideline, not financial advice. Your ideal split depends on your costs and goals.

FAQ

What is the 50/30/20 budget rule?

It is a simple way to divide your after-tax income: 50% to needs (housing, food, utilities, transport, insurance, minimum debt payments), 30% to wants (dining out, subscriptions, hobbies, travel) and 20% to savings and extra debt repayment. It is popular because it is easy to remember and flexible.

Should I use my gross or net income?

Use your net (after-tax, take-home) income — the amount that actually lands in your account. The 50/30/20 split is designed around what you can actually spend, not your headline salary before deductions.

What if 50/30/20 does not fit my situation?

It is a starting point, not a rule. In high-cost areas needs often exceed 50%, while aggressive savers might do 50/20/30 or more toward savings. This calculator lets you change all three percentages — just keep them adding to 100%.

What counts as a need versus a want?

Needs are things you must pay to live and work: rent or mortgage, groceries, utilities, basic transport, insurance and minimum loan payments. Wants are everything you choose: eating out, streaming, new gadgets, holidays. A useful test — if you lost your income, would you have to keep paying it? If yes, it is a need.
