Unfair Dismissal Compensation Calculator 2026/27

Estimate what an employment tribunal could award for unfair dismissal: the fixed basic award plus a compensatory award built from actual lost earnings, the way tribunals work it out. Updated October 2026 for the Employment Rights Act 2025 changes.

Quick answer

Unfair dismissal compensation has two parts. The basic award uses the statutory redundancy formula (up to £22,530 in 2026/27). The compensatory award covers lost net pay and pension, capped at the lower of 52 weeks' gross pay or £123,543 for dismissals before 1 January 2027, when the cap is abolished. The median award is about £6,700.

Estimate only. Tribunals decide what loss is just and equitable, can reduce awards where the employee did not look for work (failure to mitigate) or would have been dismissed fairly anyway (a Polkey reduction), and use the employee's actual net pay. Net pay here is estimated with England, Wales and NI tax bands.

How unfair dismissal compensation is calculated

1. The basic award

The basic award uses the same formula as statutory redundancy pay: for each complete year of service (up to 20, counted back from the dismissal date) the employee gets half a week's pay for years under 22, one week for years aged 22 to 40 and one and a half weeks for years aged 41 and over. A week's pay is capped at £751 from 6 April 2026, so the maximum is £22,530. If the employee already received statutory redundancy pay for the same dismissal, it is deducted.

2. The compensatory award

The compensatory award puts the employee back in the financial position they would have been in. It is built from net weekly pay (after tax and NI), lost employer pension contributions and benefits, the expected time to find comparable work, and a small sum for loss of statutory rights. Earnings from a new job and any notice pay already received are deducted.

For dismissals with an effective date before 1 January 2027, it is capped at the lower of 52 weeks' gross pay or £123,543. The Employment Rights Act 2025 removes the cap for dismissals on or after 1 January 2027, and cuts the qualifying service for most claims from two years to six months from the same date. The cap has never applied to dismissals for whistleblowing or certain health and safety reasons.

3. Adjustments

How much do tribunals actually award?

Ministry of Justice tribunal statistics for April 2023 to March 2024 put the median unfair dismissal award at £6,746 and the mean at £13,749. Most awards are far below the statutory cap because the compensatory award is limited to actual loss, and most people find new work within months. Many claims never reach a hearing and settle through Acas early conciliation or a settlement agreement.

Is unfair dismissal compensation taxed?

Awards for the loss of a job fall under the termination payment rules: the first £30,000 is free of income tax and National Insurance, and anything above is taxed as income. Any part that is really unpaid wages, notice or holiday pay is taxed as earnings. The settlement agreement calculator shows the after-tax figure.

Unfair dismissal compensation questions

How much compensation do you get for unfair dismissal?
It is the basic award plus the compensatory award. The basic award uses the statutory redundancy formula (maximum £22,530 in 2026/27). The compensatory award covers actual lost net pay and pension, capped at the lower of 52 weeks' gross pay or £123,543 for dismissals before 1 January 2027. Ministry of Justice figures put the median award at £6,746 (2023/24).
What is the maximum unfair dismissal award in 2026/27?
For a dismissal before 1 January 2027 the maximum is £22,530 basic award plus a compensatory award of up to £123,543 (or 52 weeks' gross pay if lower). From 1 January 2027 the Employment Rights Act 2025 removes the compensatory cap, so awards are limited only by proven loss.
How is the basic award for unfair dismissal calculated?
Count back complete years of service from the dismissal date, up to 20. Each year earns half a week's pay if the employee was under 22, one week's pay if aged 22 to 40, and one and a half weeks' pay if aged 41 or over. A week's pay is capped at £751 from 6 April 2026.
How long do you need to work somewhere to claim unfair dismissal?
Two years' continuous service for dismissals before 1 January 2027. The Employment Rights Act 2025 cuts this to six months for dismissals on or after 1 January 2027. Automatically unfair reasons, such as whistleblowing or pregnancy, need no qualifying service.
Is unfair dismissal compensation taxable?
The first £30,000 of compensation for losing a job is free of income tax and National Insurance. Anything above £30,000 is taxed as income, and any part that represents unpaid wages, notice pay or holiday pay is taxed as earnings.
