Wrongful Dismissal Compensation Calculator 2026

Calculate compensation for wrongful dismissal when your employer dismisses you without proper notice. This calculator works out your notice pay and lost benefits.

How Wrongful Dismissal Compensation Works

Wrongful dismissal is a breach of contract claim. Your compensation equals what you should have received during your notice period.

What You Can Claim

Component	What's Included
Notice pay	Salary you would have earned during notice period
Pension	Employer contributions during notice period
Company car	Cash equivalent or benefit-in-kind value
Healthcare	Value of private medical insurance
Other benefits	Gym membership, phone, childcare vouchers
Bonuses	Pro-rata bonus if payable during notice

What's NOT Included

• Future losses beyond notice period
• Compensation for hurt feelings
• Injury to reputation
• Loss of statutory rights
• Punitive damages

This is why wrongful dismissal claims are usually lower than unfair dismissal claims.

Notice Period Calculation

Your notice period determines your compensation:

Statutory Minimum Notice

Length of Service	Statutory Notice
Less than 1 month	None
1 month to 2 years	1 week
2 to 12 years	1 week per year
12+ years	12 weeks

Contractual Notice

Your employment contract may give:

• Longer notice than statutory
• Fixed notice (e.g., 3 months regardless of service)
• Garden leave provisions

Always use the LONGER of statutory or contractual notice.

Components of Your Claim

1. Gross Notice Pay

Your salary for the notice period:

Formula: Annual salary ÷ 52 × notice weeks

Example: £52,000 salary, 8 weeks notice

• £52,000 ÷ 52 = £1,000/week
• £1,000 × 8 = £8,000 gross

2. Loss of Benefits

Pension

• Employer contributions during notice period
• Example: 5% of £52,000 = £2,600/year
• 8 weeks = £2,600 ÷ 52 × 8 = £400

Company Car

Use the taxable benefit (P11D) value:

• Annual BIK value: £4,000
• 8 weeks = £4,000 ÷ 52 × 8 = £615

Or if cash allowance:

• £500/month allowance
• 8 weeks = £500 × (8÷4.33) = £923

Healthcare

• Annual premium cost
• Example: £1,200/year
• 8 weeks = £1,200 ÷ 52 × 8 = £185

Other Benefits

Value at cost to replace or provide:

• Phone: £50/month
• Gym: £40/month
• Childcare vouchers: £243/month
• Life insurance: Premium value

3. Bonus

If bonus is contractual and would be paid during notice:

• Pro-rata the annual bonus
• Example: £10,000 annual bonus
• 8 weeks = £10,000 ÷ 52 × 8 = £1,538

Note: Discretionary bonuses are harder to claim.

Tax Treatment

Wrongful dismissal compensation is treated as employment income:

Notice Pay

• Subject to income tax
• Subject to National Insurance
• Taxed as if you were still employed

Benefits

• Taxed at the rate you would have paid
• No special tax treatment

Exception: The first £30,000 of termination payments may be tax-free if structured correctly, but this usually only applies to ex-gratia payments, not contractual notice pay.

Example Calculations

Example 1: Basic Claim

Employee: £40,000 salary, 5% pension, 6 weeks contractual notice

Component	Calculation	Amount
Notice pay	£40,000 ÷ 52 × 6	£4,615
Pension loss	£2,000 ÷ 52 × 6	£231
Total gross		£4,846

Example 2: With Benefits

Employee: £65,000 salary, 8 weeks notice, car, healthcare

Component	Calculation	Amount
Notice pay	£65,000 ÷ 52 × 8	£10,000
Pension (6%)	£3,900 ÷ 52 × 8	£600
Company car	£5,000 BIK ÷ 52 × 8	£769
Healthcare	£1,500 ÷ 52 × 8	£231
Total gross		£11,600

Example 3: Senior Employee

Employee: £120,000 salary, 12 weeks notice, full package

Component	Calculation	Amount
Notice pay	£120,000 ÷ 52 × 12	£27,692
Pension (8%)	£9,600 ÷ 52 × 12	£2,215
Company car	£8,000 BIK ÷ 52 × 12	£1,846
Healthcare	£2,000 ÷ 52 × 12	£462
Bonus (pro-rata)	£20,000 ÷ 52 × 12	£4,615
Total gross		£36,830

Deductions From Your Claim

Mitigation

You have a duty to mitigate your losses:

• If you find new work during notice period
• Earnings deducted from what you would have received
• Must make reasonable efforts to find work

Example:

• 8 weeks notice pay: £8,000
• Found new job after 4 weeks earning £500/week
• Deduction: 4 weeks × £500 = £2,000
• Net claim: £6,000

Payments Already Made

Deduct any payments you've already received:

• Payment in lieu of notice (PILON)
• Ex-gratia payments
• Accrued but unpaid holiday pay

When Wrongful Dismissal Happens

Common Scenarios

1. Summary dismissal without cause

   • Dismissed for "gross misconduct" that doesn't meet the threshold
   • No investigation or evidence of serious breach

2. Dismissal with insufficient notice

   • Given 4 weeks when contract says 12 weeks
   • Employer doesn't pay in lieu

3. Constructive dismissal

   • Forced to resign due to breach of contract
   • Can claim notice pay you would have received

4. Fixed-term contract terminated early

   • Contract had 12 months remaining
   • Employer terminates without cause
   • Compensation = remaining months' pay + benefits

Wrongful vs Unfair Dismissal

Factor	Wrongful Dismissal	Unfair Dismissal
Legal basis	Breach of contract	Employment Rights Act 1996
Service required	None	Usually 2 years
Compensation	Notice period pay + benefits	Basic + compensatory awards
Maximum	No statutory cap	Capped at £22,530 (basic) + £123,543 (compensatory)
Time limit	6 years (contract)	3 months minus 1 day
Where to claim	County Court or tribunal	Employment tribunal

You can claim both - but be aware of overlapping awards.

Making Your Claim

1. Calculate Your Loss

Use this calculator to work out:

• Gross notice pay
• Value of benefits lost
• Total gross compensation

2. Send Letter Before Action

Write to employer demanding:

• Payment in lieu of notice
• Benefits for notice period
• 14 days to respond

3. Choose Your Forum

Employment Tribunal:

• Claim alongside unfair dismissal
• 3-month time limit
• No court fees
• Limited compensation (tribunal's jurisdiction)

County Court:

• Standalone breach of contract claim
• 6-year time limit
• Court fees apply
• No cap on compensation

4. Consider Settlement

Most wrongful dismissal claims settle:

• Quicker resolution
• Certainty of outcome
• Avoid legal costs
• Tax-efficient structuring possible

Limitations

No Compensation For

• Hurt feelings or distress (unless discrimination involved)
• Damage to reputation
• Difficulty finding work
• Manner of dismissal
• Loss of statutory rights

These can be claimed in unfair dismissal, not wrongful dismissal.

Short Notice Periods

If your notice period is short (e.g., 1 week):

• Your wrongful dismissal claim may be small
• Unfair dismissal may give higher compensation
• Consider which claim to prioritize

When To Claim Wrongful Dismissal

Prioritize wrongful dismissal when:

• You don't have 2 years' service (can't claim unfair dismissal)
• You have a long notice period (3-6 months)
• You're highly paid with substantial benefits
• Breach of contract is clear-cut
• You want to claim in County Court (no 3-month limit)

Prioritize unfair dismissal when:

• You have 2+ years' service
• Notice period is short
• You have significant future losses
• You want to avoid court fees
• The dismissal was unreasonable or discriminatory

Next Steps
