Estimate tax owed against an editable bracket table, with your effective and marginal rate broken out.
Progressive bracket calculation.
In a progressive system, your entire income isn't taxed at one rate. Instead, each slice of income between bracket thresholds is taxed at that bracket's own rate — the sample table above shows this directly, and the estimate sums the tax owed slice by slice rather than applying a single flat rate to everything.
Your marginal rate is the rate applied to your last dollar earned — useful for judging the tax impact of a raise or extra income. Your effective rate is total tax divided by total income, which is almost always lower than the marginal rate and better reflects your overall tax burden.
Tax brackets differ by country, by state or province, and by filing status, and they change most years. Rather than guess wrong, this tool ships with a simple illustrative table you can overwrite with your own jurisdiction's actual current brackets.
They're illustrative U.S.-style sample brackets and won't match every country, state, or filing status. Replace the numbers in the table with your own jurisdiction's current published brackets for an accurate estimate.
No — it estimates income tax against the bracket table you provide only. Add additional line items yourself if you want to account for payroll or local taxes.
It's subtracted from gross income before the bracket calculation runs, approximating a standard deduction or personal allowance. Set it to 0 if your situation uses itemized deductions instead.
