Bracket Creep Calculator

Bracket creep is the tax authority's most elegant trick: a tax increase nobody has to vote for. The German income tax tariff rises progressively, meaning each extra euro is taxed higher. When your wages rise with inflation but the tariff doesn't follow, you pay a higher tax share on the same real prosperity. The calculator shows exactly how much of that is missing from your pocket.

The tool simulates your tax burden over several years. You enter your gross income, your expected raises and the inflation rate. The calculator then compares two worlds: one with the actual tax tariff, one with a tariff cleanly adjusted for inflation. The difference is your hidden tax - the part of your raise that goes only to the tax office.

The calculation uses the official BMF tax formulas under Section 32a of the Income Tax Act, the same ones your payroll office uses. These are not estimates or rules of thumb but the real tariff function with its progression zones. That is why the numbers match what ends up on your payslip.

The marginal rate visualization shows what happens to the next euro you earn. Many believe a higher tax rate applies retroactively to the whole income - it doesn't. The calculator makes clear that only the part above a threshold is taxed higher, and exactly where your personal marginal rate sits.

A dedicated view covers the history of the basic allowance from 2015 to 2026. The Grundfreibetrag rose from 8,472 euros to over 12,000 euros - but was that enough to offset inflation? The calculator lays out the annual adjustments so you can see in which years the legislature caught up and in which bracket creep hit unchecked.

The break-even analysis answers the question that really counts: from what raise onward does anything remain in real terms? The calculator tells you how big your raise would have to be to beat inflation and bracket creep together. This is not tax advice but an honest reality check for your next salary negotiation.
