Use the calculator below to get a quick, private estimate of what a fair settlement agreement might look like for you: the amounts you are owed, a sensible range for the compensation on top, and roughly how much is tax-free. It takes two minutes and costs nothing. A calculator cannot see the strength of your legal claims, though, which is what really drives the number, so treat the result as a starting point and let a specialist check your actual offer.
Most people facing a settlement agreement just want one thing first: a number. This tool gives you a realistic range, then explains what moves it, so you walk into any conversation informed rather than guessing.

What the calculator is doing
Your estimate is built from two parts. The first is what you are owed regardless: notice pay, any unpaid salary, accrued holiday, and statutory redundancy if it applies. The second is the ex gratia compensation on top, the negotiable part, which the tool shows as a range (commonly one to six months' gross pay) because the right figure depends on facts a calculator cannot measure.
What the calculator cannot see
The single biggest driver of your compensation is the strength of the claims you would be giving up. A strong unfair dismissal, discrimination or whistleblowing claim can move your figure well beyond a generic estimate; no claim at all pulls it down. Two people on the same salary can settle for very different amounts for this reason. That is why the tool gives a range, not a promise, and why a specialist review is the real way to know your number.
How tax affects your take-home
Genuine compensation is tax-free up to £30,000; notice, salary, holiday and bonuses are taxed as earnings. The calculator gives an indicative tax-free amount and estimated take-home, but your employer's payroll calculates the exact figures (including Post Employment Notice Pay).
