Marginal rate — the bracket your last dollar hits

Understanding your total tax

Income tax, payroll tax, and state tax — plus the rates that actually matter.

🧮

Three taxes, one bill

Your total burden combines federal income tax (progressive brackets after the standard deduction), payroll tax for Social Security and Medicare, and any state income tax. Seeing them together is the real picture.

📊

Effective beats marginal for planning

Your top bracket is scary, but you never pay that rate on every dollar. The effective rate — what you actually pay overall — is the number that tells you your true take-home.

🌍

US and UK supported

Switch to the UK to model income tax with the tapered personal allowance and employee National Insurance instead of FICA and state tax. Both use the current statutory tables.

How the Tax Calculator Works

Formula

taxableIncome = max(0, gross − standardDeduction) incomeTax = progressive over the year's brackets payrollTax = Social Security (6.2% to wage base) + Medicare (1.45% + 0.9% high earners) stateTax = gross × state rate totalTax = incomeTax + payrollTax + stateTax effectiveRate = totalTax ÷ gross
1

2

5

Review your tax

See total tax, effective and marginal rates, and what you keep.

Income tax is applied progressively across brackets after the standard deduction (or UK personal allowance), so only the income within each band is taxed at that band's rate. State tax here uses the top marginal rate as a simple estimate; your actual state return may apply its own brackets and deductions.

Figures use the 2026 statutory tax tables — US IRS brackets, standard deduction, and FICA rates, and UK HMRC bands, the tapered personal allowance, and employee National Insurance. They update on the legislative schedule and are estimates for planning, not tax advice.
