Choosing between two permanent roles involves more than just comparing headline salaries, what really matters is your take‑home pay after Income Tax and National Insurance. Our Permanent Salary Comparison Calculator does the detailed tax work for you, so you can negotiate offers and plan your budget with absolute clarity.
By entering two gross annual salaries and your personal tax code (1257L if you’re on the standard allowance for 2025/26), you’ll instantly see side‑by‑side net figures: both annual and monthly take‑home pay, plus the exact pound‑and‑pence difference between them. We apply the latest UK Income Tax bands, personal allowance and Class 1 NI thresholds to ensure your comparison is fully up to date.
