About the Income Tax Calculator

A progressive income tax calculator you configure with your own bands and rates, so it works in any jurisdiction rather than only one. Enter your income and a tax-free allowance, set the bands, and the tax due in each is calculated and totalled.

The output that changes how people think about tax is the pair of rates. Your marginal rate is the percentage charged on your next unit of income; your effective rate is total tax divided by total income, and it is always lower under a progressive system. Being pushed into a higher band never reduces your take-home pay, because only the income above the threshold is taxed at the higher rate, and seeing tax broken out band by band makes that unmistakable.

Key features of the Income Tax Calculator

Bands you configure

Set your own thresholds and rates, so the calculator is not tied to one country's tax year.

Marginal versus effective

Your marginal rate applies to your next unit of income; your effective rate is total tax over total income, and it is always lower under a progressive system.

The band myth dispelled

Being pushed into a higher band never reduces take-home pay, because only the income above the threshold is taxed higher.

Band-by-band breakdown

Tax is broken out per band, which makes the structure unmistakable rather than a single deduction.

Tax-free allowance handled

The personal allowance is applied before the bands, as it is in practice.

Frequently asked questions

The marginal rate is what you pay on your next unit of income, the top band you reach. The effective rate is your total tax divided by your total income, which is always lower because earlier bands are taxed less.
