Budget Calculator (50/30/20)
Split your take-home pay into needs, wants, and savings with the 50/30/20 rule.
Open calculatorIncome & Business
Enter your gross salary, effective tax rate, and deductions to estimate your real monthly and per-paycheck take-home pay.
Your pre-tax retirement contribution is subtracted from your gross salary first (that's what "pre-tax" means — it reduces your taxable income). Your effective tax rate is then applied to what remains, other deductions are subtracted, and the result is your take-home pay.
Why we ask for your tax rate instead of calculating it: real tax bills depend on your location, filing status, credits, and rules that change every year. Calculators that hide those assumptions are precise-looking but often wrong. Here you control the number — which means the result is honest, and you can test scenarios in seconds.
Your monthly take-home figure is the correct input for budgeting — feed it straight into the 50/30/20 Budget Calculator. And notice what the retirement line shows: raising your contribution 1% barely dents the monthly figure, because part of it comes from money that would have gone to taxes.
