Is a pay rise always worth it?
Because the UK has a progressive tax system, a gross pay rise never translates fully into take-home pay — and crossing into the 40% higher-rate band, or losing the Personal Allowance above £100,000, can mean a surprisingly small net gain. This tool shows you the real difference in your pocket so you can judge whether a higher-stress role or longer commute is genuinely worth it.
