Work out salary increment after tax instantly with clear inputs, formula shown and shareable results.
An increment is taxed entirely at your marginal rate, since it sits on top of existing income. At a 30% marginal rate a 12% raise adds only about 8.4% to take-home pay.
Net increment
Net = current × hike × (1 - marginal rate)
Tax figures are estimates based on the rates, caps and thresholds you enter. Real rules differ by jurisdiction and change every year, and personal circumstances alter the outcome. This is not tax or financial advice — confirm with a qualified adviser.
Because the whole increase is taxed at your top rate, and statutory contributions often rise with it too.
Directing part of the increase to pension or other pre-tax benefits keeps more of it working for you.
