Effective Tax Rate Calculator
Your effective tax rate is the percentage of your total income you actually pay in tax — quite different from your marginal rate, which only applies to your last euro earned. Enter your gross income and the tax you actually paid, and see at a glance how heavy your real tax burden is.

How this was calculated
- 1Tax paid ÷ gross income￥15,000 ÷ ￥60,000 = 25%
公式
Effective rate = (tax paid ÷ gross income) × 100
This is a simple ratio: your total tax amount divided by your total income, multiplied by 100 for a percentage. Because a progressive system only taxes the portion above a threshold at a higher rate, your effective rate is almost always lower than your top (marginal) bracket. The bigger the gap between effective and marginal rate, the more of your income falls into lower brackets.
ステップ解説
- 1Enter your gross income — your total income before tax.
- 2Enter the tax you actually paid, for example from your assessment or payslip.
- 3Read off your effective rate and net income, and compare it with your marginal rate.
計算例
€ 60,000 gross, € 15,000 tax paid
→ 15,000 ÷ 60,000 × 100 = an effective rate of 25%; net € 45,000.
€ 35,000 gross, € 6,300 tax paid
→ 6,300 ÷ 35,000 × 100 = an effective rate of 18%; net € 28,700.
€ 120,000 gross, € 42,000 tax paid
→ 42,000 ÷ 120,000 × 100 = an effective rate of 35%; net € 78,000.

- Treating net income as "what's left to save", without accounting for fixed expenses.
活用シーン
- Comparing your actual tax burden across different years or situations.

よくある質問
Why is my effective rate lower than my top tax bracket?
Because only the part of your income above the bracket threshold is taxed at the top rate; the rest falls into lower brackets with a lower rate.
What is the difference between the effective and marginal rate?
The marginal rate applies to your last euro earned; the effective rate is your total tax divided by your total income. So the marginal rate is always equal to or higher than the effective rate.
Do social insurance contributions count as tax?
In the Netherlands, social insurance contributions are often levied together with income tax and included in the lower brackets, so your "tax paid" typically includes those contributions.
Can my effective rate be higher than my marginal rate?
No, that cannot happen under a progressive system: the effective rate is always a weighted average of the rates across lower and higher brackets, so it can never exceed the highest (marginal) rate you pay.
