What is the difference between effective and marginal tax rate?

The marginal rate is the rate applied to your last dollar of income — the top bracket you fall into. The effective rate is the average rate across all your income: total tax ÷ gross income × 100.

Are these tax calculations accurate?

Results are estimates based on simplified bracket structures. Tax rules change annually and vary based on filing status, credits, and other factors. Always consult a qualified tax professional for your actual liability.

What is a tax bracket?

A tax bracket is a range of income taxed at a specific rate. Progressive tax systems tax different portions of your income at different rates — you only pay the higher rate on income within that bracket, not on all your income.

What deductions can I enter?

Enter any pre-tax deductions: standard deduction, personal allowance, pension contributions, etc. For the US this might be $14,600 (standard deduction 2024 single). For UK it is £12,570 personal allowance.

Why is my effective rate lower than my marginal rate?

Because only the income above each bracket threshold is taxed at the higher rate. Income below each threshold is taxed at the lower rate for that band — so your overall average is always lower than your top rate.

Is my income data kept private?

Yes. All calculations run locally in your browser. No financial data is transmitted to our servers.
