Unfair Dismissal Compensation Estimator

Estimate tribunal exposure: basic and compensatory awards plus ACAS uplift.

Estimated tribunal award

£20,750.00

Basic award £3,250.00 · Compensatory £17,500.00 · ACAS uplift £0.00.

How this is calculated

The basic award mirrors the statutory redundancy formula: weeks per year of service depending on age, with weekly pay capped at £700 (2026/27).

The compensatory award reflects loss of earnings and benefits since dismissal, capped at the lower of 52 weeks' actual pay or £118,223. A tribunal can uplift the total by up to 25% for unreasonable failure to follow the ACAS Code.

Estimates only, every case turns on its facts. Always take legal advice before settling or defending a claim.

In-depth guidance

How tribunals value an unfair dismissal claim

Awards have two main parts. The basic award mirrors statutory redundancy pay. The compensatory award covers actual financial loss, which is where most of the value sits and where the biggest variables are.

The basic award

  • Half a week's pay for each year of service under 22, one week from 22 to 40, and one and a half weeks from 41.
  • Capped at 20 years of service and at the statutory weekly pay limit.
  • Reduced by any statutory redundancy payment already made, and by any conduct that makes a reduction just and equitable.

The compensatory award

  • Immediate loss of earnings from dismissal to the hearing, net of pay from any new job.
  • Future loss, based on how long the tribunal thinks it will take to find comparable work.
  • Loss of statutory rights, conventionally a modest fixed sum, plus pension loss which can be substantial in defined benefit schemes.
  • Capped at the lower of the statutory maximum or 52 weeks' gross pay, except in whistleblowing and health and safety dismissals where there is no cap.

Adjustments that move the number

ACAS Code uplift or reductionUp to 25% either way for unreasonable failure to follow the Code
Polkey reductionPercentage reduction reflecting the chance the employee would have been dismissed anyway with a fair process
Contributory faultReduction where the employee's conduct caused or contributed to the dismissal
Failure to mitigateReduction where the employee did not take reasonable steps to find new work

The real cost of defending a claim

Costs orders are rare in the employment tribunal, so each side normally bears its own legal fees. A defended claim reaching a three-day final hearing typically takes 12 to 18 months and consumes significant management time in disclosure, witness statements and preparation.

This is why commercial settlement often makes sense even in a defensible case. ACAS early conciliation is free, confidential, and available before a claim is issued, and a settlement agreement gives you a clean waiver of claims.

Use the estimate as a range

The estimator above gives an indicative exposure. It cannot price the strength of your process, the credibility of witnesses, or any discrimination element, all of which shift the number significantly. Treat it as the starting point for a conversation, not a settlement figure.
