Tax Bracket Calculator

A progressive tax system taxes each slice of income at its own rate. Your bracket is the rate on the last dollar you earn, not the rate on all of it, and the difference between the two is the source of most confusion about taxes.

Income after tax: $47,000.00

Values update as you type. This calculator covers the single scenario its formula assumes — see Common Mistakes for what it leaves out.

The formula this calculator uses

Tax = sum of (income in each bracket x that bracket's rate)

income: Taxable income for the year
brackets: Income bands and the rate applied to each
marginalRate: The rate on your last dollar of income
effectiveRate: Total tax divided by total income

How to check the result by hand

1
Find your taxable income
Start from gross income and subtract any standard deduction, personal allowance or other deductions the code allows.
2
List the brackets
Write down each band's lower and upper limit and the rate that applies within it, in order from lowest to highest.
3
Tax each slice
Multiply the income falling in each band by that band's rate. The lowest band is taxed first, then the next, and so on.
4
Add the slices
Sum the tax from every band to get total tax. Only the top slice is taxed at the highest rate you reach.
5
Compute both rates
Your marginal rate is the top band's rate; your effective rate is total tax divided by income. The gap between them is the progressive structure at work.
