How it works
Enter the gross pay rise and the monthly costs that go up because you earn more. The calculator also solves for the gross pay rise you would need just to cover them, which shows how steep the effective tax on extra pay can be.
Check whether a pay rise still leaves you better off once childcare, rent increases or lost benefits are counted, and how big a rise you would need.
