Two-Year Salary Comparison

This calculator compares your salary from two different years to see whether a nominal pay rise has translated into more money in your pocket after tax threshold and NI changes.

Enter two salary levels for the same person to compare scenarios — for example, your pre-promotion salary versus a proposed new salary after a pay review, or two job offers from different companies. Unlike the two-salaries comparison which assumes these are alternative single incomes, this tool can model combined scenarios. The side-by-side breakdown shows income tax, NI, and take-home for each, with the difference highlighted. Scotland rates apply to both columns when selected. Use the result to build a factual case for a pay increase — showing a manager the exact net difference demonstrates you have done your homework rather than simply asking for more.
