Estimate your income tax and what you keep. This free income tax calculator shows your taxable income, tax owed, after-tax income and effective rate from your income, deductions and tax rate.
Estimate only. You supply the effective tax rate, since real brackets depend on your country, tax year and filing status.
How Income Tax Calculator Works
Curious what you’d actually take home from a given salary? This free income tax calculator applies an effective tax rate you supply to your gross income and deductions to estimate your taxable income, tax owed, and after-tax income.
Formula: Taxable Income = max(Gross Income − Deductions, 0). Income Tax = Taxable Income × Effective Rate ÷ 100. After-Tax Income = Gross Income − Income Tax. Rather than modeling tiered tax brackets, which vary by country, tax year, and filing status, this calculator applies a single effective rate you enter directly to your taxable income.
- Annual gross income — your total income before any taxes or deductions
- Deductions / allowances — optional amount subtracted from gross income before tax is applied
- Effective tax rate — the overall percentage of your taxable income you expect to pay in tax
Example Scenarios
| Gross Income | Deductions | Effective Rate | Taxable Income | Income Tax | After-Tax Income |
|---|---|---|---|---|---|
| $60,000 | $10,000 | 15% | $50,000 | $7,500 | $52,500 |
| $80,000 | $0 | 20% | $80,000 | $16,000 | $64,000 |
| $45,000 | $5,000 | 12% | $40,000 | $4,800 | $40,200 |
| $120,000 | $20,000 | 24% | $100,000 | $24,000 | $96,000 |
| $35,000 | $0 | 10% | $35,000 | $3,500 | $31,500 |
Note: these examples use round, illustrative effective tax rates to demonstrate the math clearly — they are not real current tax brackets or thresholds, since actual rates depend on your country, tax year, income level, and filing status.
Income Tax Calculator FAQ
Why do I need to enter my own tax rate instead of the calculator finding it automatically?
Real tax systems use tiered brackets, credits, and rules that differ by country, tax year, and filing status, so a single generic formula can’t accurately reproduce them. Entering your own effective rate — the overall percentage you actually pay — keeps the estimate honest and lets you use the calculator anywhere.What’s the difference between taxable income and gross income?
Gross income is everything you earn before any deductions. Taxable income is what’s left after subtracting deductions or allowances, and it’s the amount your effective tax rate is actually applied to in this calculator.Where do I find my effective tax rate?
Your effective rate is your total tax paid divided by your total income, which you can calculate from a prior tax return or pay stub, or estimate using an official tax authority’s rate schedule or withholding tables for your situation.Does this calculator include state, local, or payroll taxes?
Only if you build them into the effective rate you enter. Since this calculator uses one combined rate, you can include state, local, and other applicable taxes by adding their effective impact into the rate field yourself.Can I use this to estimate take-home pay from a paycheck?
It gives a rough annual estimate, but a dedicated paycheck calculator will better capture per-period withholding, pre-tax benefits, and payroll-specific deductions that this simplified tool doesn’t model.Why is my effective rate lower than my top tax bracket?
In a bracketed system, only income within each bracket is taxed at that bracket’s rate — lower portions of your income are taxed at lower rates first. Your effective rate blends all those brackets together, so it’s typically lower than the top rate that applies to your last dollar earned.Related Calculators
