UK Salary Comparison Calculator

When evaluating a job offer or considering a career move, the headline salary figure can be misleading. A £5,000 pay rise sounds significant, but after income tax, National Insurance, and pension contributions, the actual increase in your monthly take-home pay may be considerably less. Our salary comparison calculator lets you enter two gross salaries and see the real difference in net take-home pay side by side, accounting for the full UK tax and NI system for 2024/25. This is particularly useful when comparing a salary increase against a reduction in benefits, or when weighing up a higher-paying role that requires a longer commute or loss of pension contributions.
