Your effective tax rate explained for new graduates, with a worked example, a checklist and the mistakes to avoid.

Why this matters for new graduates

A first full-time job brings the first real payslip, and understanding the deductions on it builds good habits early.

Worked example

Here is the calculation with sample figures. Change any number in the Effective Tax Rate Calculator to run your own.

Your effective tax rate: how it works

Your effective rate is total tax divided by total income. It tells you what share of your income actually goes to tax.

It is the right number for budgeting and for comparing years, while the marginal rate is the right number for deciding whether extra income or a deduction is worth it.

A second example with larger figures

Scaling the inputs up shows how the result moves. Percentages stay the same, so the tax grows in proportion to the amount it is applied to.

Using the calculator step by step

1. Open the Effective Tax Rate Calculator.
2. Enter your own figures on each numbered line.
3. Set the rate to the one that applies to you. Defaults are examples, not advice.
4. Read the result and the formula below it.
