What this income tax calculator shows you
An income tax calculator estimates how much income tax you’ll owe and your after-tax income. Enter your annual income, deductions and tax rate, and it returns your taxable income, income tax, after-tax (net) income and effective tax rate.
Important: income tax is charged in brackets that differ by country, tax year and filing status, so no single formula fits everyone. This calculator uses an effective tax rate you enter to stay accurate worldwide. To find yours, divide the total income tax on last year’s return by your gross income.
How to use the income tax calculator
Enter your annual gross income. Your total income before tax.
Add deductions or allowances (optional). The standard deduction or personal allowance reduces taxable income.
Enter your effective tax rate. Your overall percentage of income paid in tax.
Read your result. Taxable income, tax and after-tax income update instantly.
Marginal vs effective tax rate
Your marginal rate is the rate on your last dollar of income — the top bracket you reach. Your effective rate is the average rate across all your income, which is lower because earlier brackets are taxed less. This calculator uses the effective rate, the best single number for estimating total tax.
How income tax is calculated
Taxable income = Gross income − Deductions
Income tax = Taxable income × Effective rate
After-tax income = Gross income − Income tax
Deductions and allowances lower the income that’s actually taxed, which is why two people with the same salary can owe different amounts.

Income Tax Calculator FAQ
How do I estimate my income tax?
Subtract deductions from your gross income to get taxable income, then multiply by your effective tax rate. For $60,000 income with a $13,850 deduction at a 15% rate on taxable income, the tax is about $6,923.
What is the difference between marginal and effective tax rate?
Your marginal rate is the rate on your last dollar earned — your top bracket. Your effective rate is the average rate across all your income, which is lower. This calculator uses the effective rate.
Why do I have to enter my own tax rate?
Income tax brackets differ by country, tax year and filing status, so no single formula works everywhere. Entering your effective rate — last year's total tax divided by your gross income — keeps the estimate accurate for you.
What are deductions and allowances?
They're amounts subtracted from your income before tax is applied, such as the standard deduction or a personal allowance. They lower your taxable income and therefore your tax.
Does this calculator include payroll or social security taxes?
No. It estimates income tax only. Payroll taxes like social security and Medicare are separate — a paycheck calculator that uses your combined rate captures those.
Is the income tax calculator free to use?
Yes, this income tax calculator is completely free, needs no sign-up, and gives instant results directly in your browser.
