Step 1 · Starting targets

Enter monthly take-home income

Use income after taxes and deductions. Nothing is uploaded or saved.

Formatting only; no exchange-rate conversion.

Required. Enter a positive monthly amount, with up to two decimal places, no greater than 1 trillion.

Budget split

Use at most one decimal place. The three values must total 100%.

Total: 100%. The three percentages must each be 0–100, use at most one decimal place, and total exactly 100%.

How the 50/30/20 calculation works

Start with monthly take-home income. Multiply it by 0.50 for needs, 0.30 for wants, and 0.20 for savings and extra debt payments.

This is a rule of thumb described in the CFPB Analyzing Budgets worksheet, not a required allocation.

Needs target
take-home income × 0.50
Wants target
take-home income × 0.30
Savings + extra debt target
take-home income × 0.20

Worked example

With $5,000 of monthly take-home income, the starting amounts are $2,500 for needs, $1,500 for wants, and $1,000 for savings or extra debt payments.

If actual needs are $2,750, the needs share is 55%. That does not mean the budget failed. It shows that the remaining buckets need a deliberate adjustment or that a personalized ratio is more realistic.

Use the rule as a starting point

Needs

Housing, basic utilities, groceries, healthcare, required transport, childcare, insurance, and minimum required payments.

Wants

Dining out, entertainment, travel, hobbies, and optional upgrades. The boundary depends on your circumstances.

Savings + extra debt

Emergency savings, retirement, planned goals, and debt payments above the required minimum.

When the percentages do not fit

The CFPB budgeting hub and its personal spending-rule worksheet frame percentage rules as adaptable starting points. High housing costs, caregiving, healthcare, or urgent debt can make a different split more realistic. Protect required obligations first; do not skip food, housing, healthcare, insurance, or minimum payments to force a percentage.

If income varies, start with a conservative monthly baseline you can usually rely on. Keep irregular income separate until it arrives, then decide deliberately whether it belongs in required costs, a buffer, a goal, or extra debt.

Turn your chosen amounts into category limits

50/30/20 calculator FAQ

Should I use gross income or take-home income?

Use monthly take-home pay after taxes and payroll deductions. The CFPB describes the framework as a way to divide net or take-home income.

What belongs in the 20% bucket?

Use it for savings goals and extra debt payments. Keep minimum required debt payments with needs when they must be paid to protect your household plan.

What if my needs are more than 50%?

Treat 50% as a starting reference, not a pass/fail score. Protect housing, food, utilities, healthcare, required transport, and minimum payments first, then build a ratio that works for your circumstances.

Does this calculator save my budget?

No. The calculation runs in your browser and is not saved. Download the CSV or use the print view to save a PDF if you want to keep the comparison.
