Estimates only: Results are based on the numbers you enter and simplified assumptions. They are not a loan offer, rate quote or financial advice. Actual terms depend on the lender and your situation.

How to use this budget calculator

Enter your monthly take-home pay — what reaches your checking account after taxes and payroll deductions — and then your typical spending in each category. The calculator totals your expenses, shows how much income is left over, and converts that leftover into a savings rate, the share of your income you are keeping.

The fastest way to get accurate numbers is to pull the last two or three months of bank and credit card statements and average each category. Estimates from memory are almost always too low, especially for food, subscriptions and "miscellaneous" spending.

How the numbers are calculated

  • Total expenses = the sum of every category you enter.
  • Remaining income = take-home pay − total expenses.
  • Savings rate = remaining income ÷ take-home pay × 100.
  • Category share = category amount ÷ take-home pay × 100.

Comparing your results with the 50/30/20 rule

The 50/30/20 rule is a simple starting framework: roughly 50% of take-home pay for needs (housing, utilities, groceries, insurance, minimum debt payments), 30% for wants and 20% for savings and extra debt payoff. It is not a law of nature — in high-cost cities housing alone can take 40% or more — but it is a useful way to see which part of your budget is under pressure.

If your leftover amount is small or negative, our step-by-step guide on how to build a monthly budget walks through choosing a budgeting method and trimming the categories that matter most. Once you have a surplus, direct it first toward an emergency cushion — the emergency fund calculator will tell you how big it should be.

Frequently asked questions

What is a good savings percentage for a monthly budget?

A common benchmark is saving at least 20% of take-home pay, which is the "savings" share of the 50/30/20 rule. If that is not realistic yet, start with any consistent amount — even 5% — and raise it each time your income rises or a debt is paid off.

Should I use gross income or take-home pay in a budget?

Use take-home pay — the amount that actually lands in your bank account after taxes, retirement contributions and payroll deductions. Budgeting from gross income overstates what you can spend.

What if my expenses are higher than my income?

A negative remaining balance means you are covering the gap with savings or debt. Start with the largest categories (usually housing, transportation and food), look for recurring charges you can cancel, and read our guide on how to save money every month.

How do I budget with an irregular income?

Base your budget on your lowest typical month, not your average. In higher-earning months, move the extra into a buffer account so you can "pay yourself" a steady amount during slower months.
