Whistleblowing Compensation Calculator
Estimate whistleblowing compensation using real published UK employment tribunal awards.
Important Context
These figures represent awarded compensation only. Many cases settle out of court for undisclosed sums. Success rate includes cases won at hearing; many withdrawn cases are also settled without a public award.
How compensation is measured in whistleblowing claims
This whistleblowing compensation calculator uses published employment tribunal judgments to give context on real awards. It is built for people trying to understand the range of outcomes, not to promise a result in any individual case. The figures combine the tribunal's visible compensation data with the claim type recorded for the judgment, so the page reflects documented decisions rather than private settlement figures or broad anecdotal estimates.
For whistleblowing, the award depends on whether the successful claim is about dismissal, detriment, or both. A whistleblowing dismissal award can include financial loss caused by the dismissal, while detriment claims can include compensation for the treatment suffered. The value often turns on causation, loss of earnings, the period of loss and whether the protected disclosure was found to be the reason for the treatment.
Discrimination and whistleblowing compensation is not assessed by a simple tariff. Some awards are modest because the proven loss is limited; others are much higher because they include long-term earnings loss, psychiatric injury, interest or multiple successful complaints. The published examples are useful because they show the spread of real outcomes rather than a single headline number.
The numbers on this page are not a prediction of any individual claim. They summarise published decisions where compensation appears in the judgment, so they are useful for context but not a complete view of every claim issued, negotiated or settled. Many employment tribunal cases settle privately, and those settlement values usually do not appear in the public judgment record.
Use the median, highest award and top published cases as a starting point for research. The median is usually more useful than the average because very large awards can pull the average upward. The top cases show what has happened in documented disputes, but they should not be treated as normal outcomes. Legal advice is still needed before relying on any number for settlement, litigation risk or pleading a schedule of loss.
