Unfair Dismissal Compensation Calculator UK 2026
Calculate your potential unfair dismissal compensation using official 2026/27 rates. This calculator estimates your basic award (like statutory redundancy pay), compensatory award (actual financial losses), and any additional awards for ACAS code breaches, discrimination, or whistleblowing — giving you a realistic figure to support your employment tribunal claim or settlement negotiation.
If you've been dismissed from your job and believe it was unfair, you may be entitled to compensation through an employment tribunal. Unfair dismissal awards in the UK consist of multiple components with complex caps, age-based multipliers, and service length calculations. Understanding your potential compensation is crucial whether you're considering legal action, negotiating a settlement, or assessing the strength of your case.
This calculator uses official UK government rates for 2026/27, including the £700 statutory weekly pay cap, £115,115 compensatory award cap, and age-weighted service multipliers. You'll also receive personalised recommendations on strengthening your claim, maximising your award, and understanding your employment rights. For related employment protections, see our Redundancy Pay Calculator and Notice Period Calculator.

Calculate Your Unfair Dismissal Compensation
How Unfair Dismissal Compensation is Calculated in the UK
Step 1: Basic Award (Like Statutory Redundancy Pay)
The basic award compensates you for losing your job and is calculated using the same formula as statutory redundancy pay. Your award depends on three factors: your age at dismissal, your complete years of continuous service (up to 20 years), and your gross weekly pay (capped at £700 for 2026/27).
Age multipliers:
- Under 22: 0.5 weeks' pay per year of service
- Age 22-40: 1 week's pay per year of service
- Age 41+: 1.5 weeks' pay per year of service
Example: A 45-year-old with 10 years' service earning £850/week would receive 1.5 × 10 × £700 (capped) = £10,500 basic award. The maximum basic award is £21,000 (30 weeks × £700).
Step 2: Compensatory Award (Your Actual Financial Losses)
The compensatory award reimburses your actual financial losses caused by the dismissal. This is the most variable component and includes:
- Lost earnings: Net weekly pay × weeks unemployed (from dismissal to tribunal or new job)
- Loss of statutory rights: Standard £500-£600 award for losing unfair dismissal protection in a new job
- Pension losses: Employer pension contributions you missed (e.g. 3% × salary × weeks ÷ 52)
- Benefits losses: Company car, health insurance, bonuses, etc. (pro-rated)
- Job search expenses: Reasonable costs (travel to interviews, training, professional CV services)
- Future losses: If still unemployed at tribunal, estimated future losses until likely re-employment
The compensatory award is capped at £115,115 or one year's gross salary, whichever is lower (2026/27 rate). However, you have a duty to mitigate your losses by actively seeking work — unreasonable delays in finding employment can reduce your award.
Step 3: Notice Pay & Holiday Pay
If you were dismissed without proper notice or pay in lieu of notice (PILON), you can claim notice pay as part of your losses. Statutory minimum notice is 1 week per complete year of service (up to 12 weeks maximum), though your contract may entitle you to more. Use our Notice Period Calculator to verify your entitlement.
You can also claim untaken holiday pay if you had accrued annual leave that wasn't paid out at termination. UK workers are entitled to 5.6 weeks (28 days) statutory paid holiday per year — check our Holiday Entitlement Calculator to calculate what you're owed.
Step 4: ACAS Code of Practice Uplift (Up to 25%)
If your employer failed to follow the ACAS Code of Practice on disciplinary and grievance procedures, the tribunal can increase your compensatory award by up to 25% (or reduce it by up to 25% if you unreasonably failed to follow procedures). Common breaches include:
- Dismissing without investigation or warning
- Failing to hold a fair disciplinary hearing
- Not allowing you to appeal the decision
- Ignoring your grievance or concerns
Typical uplifts range from 10-25% depending on breach severity. This uplift applies to the compensatory award only, not the basic award.
Step 5: Additional Awards for Discrimination & Whistleblowing
If your dismissal involved discrimination (age, sex, race, disability, religion, sexual orientation, pregnancy, or maternity), you can bring a separate discrimination claim with no statutory cap. Discrimination awards include:
- Injury to feelings: £1,200–£60,000 depending on severity (Vento bands)
- Financial losses: Same as unfair dismissal, but uncapped
- Aggravated damages: If employer acted maliciously or oppressively
Similarly, whistleblowing dismissals (public interest disclosures) and health and safety dismissals have no statutory cap on compensatory awards and don't require 2 years' service. These "automatically unfair" dismissals receive stronger protection and often result in higher compensation.
Step 6: Review Total Compensation & Tribunal Strategy
Once you've calculated your estimated compensation, you'll need to decide whether to pursue an employment tribunal claim or negotiate a settlement. Most unfair dismissal cases settle before tribunal through ACAS Early Conciliation or direct negotiation, often for 60-80% of the estimated award to avoid legal costs and uncertainty.
Consider: tribunal success rates (around 50% for unfair dismissal), legal costs (£5,000-£15,000+ for representation), time delays (6-12 months), and the stress of proceedings. If you have a strong case with high compensation potential, tribunal may be worth pursuing. For borderline cases, settlement is often more practical.

Example: Unfair Dismissal Compensation for £40,000 Manager
Scenario
Sarah, 38, worked as a Marketing Manager for 6 years earning £40,000/year (£769/week). She was dismissed without warning after raising concerns about workplace bullying. She was unemployed for 16 weeks before finding a new role at £35,000/year (£673/week). She's claiming unfair dismissal and seeking compensation for her losses.
Compensation Breakdown
Basic Award:
- Age: 38 (multiplier: 1 week per year)
- Service: 6 years
- Weekly pay: £700 (capped from £769)
- Basic award: 1 × 6 × £700 = £4,200
Compensatory Award (Financial Losses):
- Lost earnings: (£769 − £0) × 16 weeks = £12,304 (before finding new job)
- Ongoing loss: (£769 − £673) × estimated 26 weeks = £2,496 (lower salary in new job)
- Loss of statutory rights: £600
- Pension loss: 3% × £40,000 × 42 weeks ÷ 52 = £970
- Job search costs: £250 (travel, professional CV)
- Total compensatory award (before uplift): £16,620
ACAS Uplift (20% for procedural breach):
- Employer failed to investigate or hold hearing
- 20% × £16,620 = £3,324 uplift
- Compensatory award after uplift: £19,944
Notice Pay (Not Paid):
- Statutory notice: 6 weeks (1 per year)
- 6 × £769 = £4,614
Holiday Pay (10 Days Untaken):
- 10 days × (£769 ÷ 5) = £1,538
Total Estimated Compensation: £30,296
(Basic £4,200 + Compensatory £19,944 + Notice £4,614 + Holiday £1,538)
Key Insights
- The ACAS uplift added £3,324 (11% of total award) due to serious procedural failures.
- Sarah's duty to mitigate was satisfied by actively seeking work and accepting a comparable role.
- The ongoing loss (lower salary in new job) reflects the tribunal's recognition that she took a pay cut to return to work quickly.
- If Sarah had also claimed discrimination or whistleblowing, the statutory cap wouldn't apply and compensation could be significantly higher.

Frequently Asked Questions
What is the maximum unfair dismissal compensation in the UK for 2026?
The maximum compensatory award for unfair dismissal in 2026/27 is £115,115 or one year's gross salary, whichever is lower. The basic award is capped at £21,000 (30 weeks × £700 statutory maximum weekly pay). So for a standard unfair dismissal claim, the absolute maximum is £136,115 (basic + compensatory).
However, these caps do not apply if your dismissal was for:
- Discrimination (age, sex, race, disability, etc.) — compensation is unlimited
- Whistleblowing (public interest disclosure) — compensatory award is uncapped
- Health and safety concerns — compensatory award is uncapped
Discrimination awards commonly exceed £50,000 and can reach six figures for serious cases involving injury to feelings, financial losses, and aggravated damages.

Who qualifies for unfair dismissal compensation in the UK?
To claim ordinary unfair dismissal, you must meet all three criteria:
- Employee status: You must be an employee, not a worker, contractor, or self-employed (check your employment contract and working arrangements)
- 2 years' continuous service: You must have worked for your employer continuously for at least 2 years (104 weeks) at the effective date of termination
- 3-month tribunal deadline: You must submit your ET1 claim form to an employment tribunal within 3 months minus 1 day of your dismissal date (ACAS Early Conciliation extends this deadline)
Exceptions — No Service Requirement:
You can claim unfair dismissal without 2 years' service if dismissed for "automatically unfair" reasons:
- Pregnancy, maternity, paternity, or adoption leave
- Whistleblowing (public interest disclosure)
- Health and safety concerns
- Asserting a statutory right (minimum wage, working time, etc.)
- Jury service or acting as an employee representative
- Discrimination (age, sex, race, disability, religion, sexual orientation)
If you're unsure about your status or service length, consult ACAS (0300 123 1100) or an employment solicitor before your tribunal deadline expires. Missing the deadline usually means losing your right to claim.
What losses can I claim in a compensatory award?
The compensatory award covers your actual financial losses caused by the unfair dismissal. You can claim:
1. Immediate Loss of Earnings:
- Net weekly pay (after tax and NI) × weeks unemployed
- From dismissal date to tribunal hearing or new job start date
- If you found a lower-paid job, claim the difference for a reasonable period
2. Loss of Statutory Rights:
- Standard award: £500-£600
- Compensates you for losing unfair dismissal protection in a new role (you'll need 2 years' service again)
3. Pension Losses:
- Employer pension contributions you would have received
- Calculate: employer contribution % × your salary × weeks unemployed ÷ 52
- Example: 3% × £40,000 × 20 weeks ÷ 52 = £461
4. Loss of Benefits:
- Company car (calculate taxable benefit value pro-rated)
- Private health insurance (premiums × weeks ÷ 52)
- Performance bonuses you would have earned
- Share options, gym membership, phone allowance, etc.
5. Job Search Expenses:
- Travel to job interviews (mileage or public transport)
- Professional CV writing or career coaching
- Training courses to improve employability
- Must be reasonable and evidenced — keep receipts
6. Future Loss of Earnings:
- If still unemployed at tribunal, estimate future losses until you're likely to find work
- Tribunal will assess: your age, skills, local job market, efforts to find work
- Typical: 6-12 months future loss for professional roles; less for readily available roles
Duty to Mitigate:
You must take reasonable steps to reduce your losses by actively seeking work, applying for suitable roles, and accepting reasonable job offers. Unreasonable refusals or delays will reduce your award. Keep evidence of your job search (applications, interviews, rejection letters) to prove mitigation.
All losses must be directly caused by the dismissal and supported by evidence (payslips, contracts, benefit statements, receipts). The tribunal will scrutinise large claims, so accuracy and documentation are essential.
Can I get more compensation if my employer discriminated against me?
Yes — discrimination claims have no statutory cap on compensation. If your dismissal involved discrimination based on a protected characteristic (age, sex, race, disability, religion, sexual orientation, pregnancy, maternity, marriage/civil partnership, or gender reassignment), you can claim:
1. Financial Losses (Uncapped):
- Same as unfair dismissal (lost earnings, pension, benefits, job search costs)
- But no £115,115 cap — you can claim your full actual losses
- Particularly valuable if you earned over £115,115/year
2. Injury to Feelings Award:
- Lower band (less serious): £1,200–£12,800
- Middle band (serious): £12,800–£38,400
- Upper band (most serious): £38,400–£64,000
- Compensates for distress, humiliation, and damage to mental health caused by discrimination
3. Aggravated Damages:
- Additional award if employer acted maliciously, vindictively, or oppressively
- Typical: £5,000–£25,000
4. Interest on Awards:
- 8% interest on injury to feelings and financial losses from dismissal date to judgment date
Key Differences from Unfair Dismissal:
- No 2-year service requirement — you can claim from day one
- Longer tribunal deadline — 3 months minus 1 day (same as unfair dismissal, but calculated from last act of discrimination)
- Uncapped compensation — awards commonly exceed £50,000; six-figure awards are not uncommon for serious cases
- Can claim alongside unfair dismissal — you'll receive both awards if successful
Example:
A 55-year-old Finance Director earning £120,000 was dismissed due to age discrimination after 15 years' service. He was unemployed for 8 months. His tribunal award:
- Basic award: £21,000 (capped)
- Compensatory award (unfair dismissal): £115,115 (capped)
- Discrimination financial loss: £80,000 (8 months lost earnings above the cap)
- Injury to feelings: £28,000 (middle band)
- Interest: £6,500
- Total: £250,615
If you believe your dismissal involved discrimination, always bring both claims (unfair dismissal + discrimination) to maximise compensation and avoid the statutory cap. Seek specialist employment law advice early — discrimination cases require strong evidence of less favourable treatment.
