How to use the Effective Tax Rate Calculator
- Enter your income, and any deductions taken off before the brackets apply.
- Enter your own tax brackets — the first must start at zero and each band meets the next.
- Choose whether the effective rate is measured against gross or taxable income.
- Compare the effective rate with the marginal rate. The gap is the point.
How it is calculated
taxable income = income − deductionstax per band = (min(taxable, band upper) − band lower) × band ratetotal tax = sum across the bandseffective rate = total tax ÷ (gross or taxable income)marginal rate = the rate on the last unit earnedThe misconception this page exists for
Someone in the 30% bracket does not pay 30% of their income in tax. On 50,000 against bands of 10% from zero, 20% from 20,000 and 30% from 40,000:
| Band | Income in it | Tax |
|---|---|---|
| 10% | 20,000 | 2,000 |
| 20% | 20,000 | 4,000 |
| 30% | 10,000 | 3,000 |
| Total | 50,000 | 9,000 |
That is an effective rate of 18% against a marginal rate of 30%. The top rate applies to the last 10,000 only. Seeing both figures side by side is the whole purpose of the page.
Two figures that disagree at a boundary, correctly
At an income of exactly 40,000, with a band starting at 40,000:
- The marginal rate is 20%, because the last unit you actually earned was in the band below the threshold.
- The tax on the next 1,000 is 300, because that next 1,000 falls entirely in the 30% band.
Both are right, and they are answering different questions. The page computes the second by taxing the extra income rather than multiplying the marginal rate by 1,000, which is what makes it correct when the next 1,000 crosses a threshold — at 19,500 it is 150, not 100, because half of it is taxed in each band.
Your own brackets
No statutory table ships here. Rates and thresholds change every year and differ in every country, and a stale table is worse than none. Enter the bands from your tax authority.
The bands must be contiguous: the first starts at zero, each one’s upper bound meets the next one’s lower bound, and only the last is open-ended. Gaps, overlaps and descending thresholds are rejected rather than quietly reordered into something you did not enter.
Practical tips
A raise never leaves you worse off under brackets alone. Cliff edges come from benefits and allowances being withdrawn, which this page does not model.
Check the effective rate against your payslip, not the marginal one. It is the figure that describes what you actually paid.
Deductions come off before the bands apply, so they save tax at your marginal rate, not your effective one.
This models brackets only. National insurance, social contributions, tapering allowances and credits are all real and all absent.
With your numbers
- Your marginal rate is 30%, but that only applies to the last slice of income
- Averaged over the whole amount, the effective rate is 18% — the gap between those two is the thing people get wrong
- Summed across the bands, the tax is $9,000.00
Quick reference
The brackets are the ones you entered. No statutory table is stored, which is what lets this page work in any country.
| Example | Total tax |
|---|---|
| 50,000 against 10/20/30 | $9,000.00 |
| 20,000, exactly on a threshold | $2,000.00 |
| 40,000, on the next threshold | $6,000.00 |
| 0 income | $0.00 |
| 75,000 with 12,000 deductions | €12,900.00 |
| 75,000 against taxable income | €12,900.00 |
| A flat 20% band | €10,000.00 |
| 120,000 across four bands | €32,000.00 |
Common questions about the Effective Tax Rate Calculator
- Why is my effective rate so much lower than my tax bracket?
- Because only the last slice of your income is taxed at the top rate. On 50,000 against bands of 10%, 20% and 30%, the first 20,000 is taxed at 10%, the next 20,000 at 20% and only the last 10,000 at 30%. The total is 9,000, which is 18% of the income — while the marginal rate is 30%. That gap is the single most common misunderstanding about progressive tax.
- Does a raise ever leave me worse off?
- Not under a bracket system like this. Moving into a higher band taxes only the income above the threshold at the higher rate; everything below it is unchanged. The page shows the tax on the next 1,000 so you can see exactly what an extra pound costs. Cliff edges do exist in real tax systems, but they come from benefits and allowances being withdrawn, not from the brackets themselves.
- Why does the marginal rate sometimes disagree with the tax on the next 1,000?
- Because they answer different questions, and at a threshold they part company. At an income of exactly 40,000 with a band starting there, the last pound you earned was taxed at 20%, so the marginal rate is 20%. But the next 1,000 falls entirely in the 30% band and costs 300. Both figures are right. The page computes the second by actually taxing the extra income rather than multiplying the marginal rate out, which is what makes it correct when the next 1,000 straddles a threshold.
- Why do I have to enter the brackets myself?
- Because a bracket table changes every year and in every jurisdiction, and a stale one on an indexed page gives confidently wrong answers. Entering them is also what makes the page work anywhere rather than for one country. Your tax authority publishes the current bands.
- Should the effective rate be against gross or taxable income?
- Both are used and they answer different questions. Against gross income it tells you what share of everything you earned went in tax, which is usually what people mean. Against taxable income it tells you the average rate the brackets applied, which is the more useful figure for comparing bracket structures. The page lets you choose.
