Quick answer
Progressive income tax applies each band’s rate only to the income falling inside that band, so tax = Σ (income in each band × that band’s rate). Moving into a higher bracket never reduces your take-home pay. Only the income above the threshold is taxed at the higher rate, which is why your effective rate is always lower than your marginal rate.

Results are estimates for general guidance and are not financial, tax or legal advice. Except where a calculator names a currency, figures carry no currency of their own: put in pounds and you get pounds back, put in rupees and you get rupees. Figures depend on the assumptions you enter and on rates that change over time. Check current rates and speak to a qualified adviser before acting on them.
About the Income Tax Calculator
Most countries use a progressive income tax system: income is divided into bands (brackets), and each band is taxed at its own rate. Only the income that falls within a band is taxed at that band's rate, so earning more never reduces your take-home pay.
Because tax brackets and rates differ by country and change every tax year, this calculator lets you enter your own brackets. Set the upper limit and rate for each band, and it computes your total tax, after-tax income, effective rate and marginal rate.
Tax = Σ (income within each band × that band’s rate)
The effective rate is total tax ÷ total income. The marginal rate is the rate applied to your last unit of income.
Consider an annual taxable income of $80,000 with the default brackets: 0% on the first $10,000, 10% on the next $30,000, 20% on the next $45,000 and 30% above $85,000. The first $10,000 is tax-free. The next $30,000 (between $10k and $40k) is taxed at 10% = $3,000. The remaining $40,000 (between $40k and $80k) is taxed at 20% = $8,000. Total tax is $11,000, leaving $69,000 take-home. Your effective rate is 13.75% even though your marginal rate is 20%, proof that being "in the 20% bracket" never means you pay 20% on all your income.
What a bracket table leaves out
A bracket table describes income tax and nothing else, which is why a calculation built from brackets alone always understates what's really taken from your pay. Most countries have at least one sizeable charge that sits completely outside the income tax schedule.
Social insurance is the usual example: National Insurance in the UK, FICA in the US, and social security contributions across much of Europe. These are usually charged on a different base, often with their own thresholds and frequently with an upper limit, so they can't be folded into the income tax bands without distorting both.
- Regional and local income taxes apply in many countries on top of the national schedule.
- Allowances that taper away at higher incomes create effective marginal rates well above the headline band rate over the taper range.
- Contributions your employer pays don't appear in any personal tax calculation, but they're part of what it costs to employ you.
Because you can edit the bands in this calculator, it can model whatever schedule you enter, but only that schedule. Anything charged separately has to be added separately.
Marginal and effective rates answer different questions
The marginal rate is the rate on your next unit of income. The effective rate is your total tax divided by your total income. They're rarely close, and using one where you need the other is the most common mistake in personal tax sums.
Take a three-band schedule of 10% to 20,000, 25% to 50,000 and 40% above. On an income of 60,000 the tax is 13,500 (an effective rate of 22.5%), while the marginal rate is 40%. Earning 10,000 more costs 4,000 in tax, because all of it falls in the top band.
- Use the marginal rate for decisions at the edge: a raise, overtime, a bonus, a deductible pension contribution.
- Use the effective rate to describe the overall burden or to compare across countries.
- Crossing into a higher band never reduces net income, because only the income above the threshold is charged at the higher rate.
Effective tax rate at different income levels (using default brackets)
| Annual income | Total tax | After-tax income | Effective rate | Marginal rate |
|---|---|---|---|---|
| $30,000 | $2,000 | $28,000 | 6.7% | 10% |
| $60,000 | $7,000 | $53,000 | 11.7% | 20% |
| $100,000 | $16,500 | $83,500 | 16.5% | 30% |
| $150,000 | $31,500 | $118,500 | 21.0% | 30% |
| $250,000 | $61,500 | $188,500 | 24.6% | 30% |
Effective rates stay well below the marginal rate at every income: the rate you "see" on the bracket label is never the rate you actually pay overall.
Frequently Asked Questions
What is the difference between effective and marginal tax rate?
⌄
The marginal rate is the rate on your highest band of income. The effective rate is your total tax divided by total income, and is always lower than the marginal rate in a progressive system.
Does moving into a higher bracket reduce my take-home pay?
⌄
No. Only the income above the bracket threshold is taxed at the higher rate. The income below it is still taxed at the lower rates.
Which brackets should I enter?
⌄
Use the official tax slabs for your country and tax year. You can add or remove bands so the calculator matches any tax system.
Is this an official tax assessment?
⌄
No. It is an estimate based on the brackets you provide and does not account for deductions, exemptions, credits or local surcharges. Consult a tax professional for filing.
What is the difference between a tax deduction and a tax credit?
⌄
A deduction reduces your taxable income before tax is calculated, so its value depends on your marginal rate. A credit reduces your tax bill directly, dollar for dollar. A $1,000 credit usually beats a $1,000 deduction.
Do I pay tax on a bonus the same as regular salary?
⌄
In most systems a bonus is taxable income and goes through the same brackets. The reason a bonus often looks heavily taxed in your payslip is withholding rules; the final tax owed is reconciled when you file your return.
How can I lower my effective tax rate?
⌄
Common ways include retirement-account contributions, health-savings contributions, charitable donations, education credits and capital losses. Every country has different incentives; check your local tax authority for the full list.

Cited to evidence the point the page makes: that each rate applies only to the income falling inside its own band, so crossing a threshold never cuts take-home pay, not because the tool is UK-specific. It takes whatever bands you give it.
