Final Pay When Leaving a Job: UK Calculator
When you leave a UK job — whether through resignation, redundancy, or end of contract — your final pay calculation involves several components beyond your regular salary. This calculator helps you estimate your total final payment, including accrued holiday, notice period pay, and any additional entitlements.
Employers are legally required to pay final wages on or before your normal payday, or within the pay period following your leaving date. They must also provide a P45 showing your total earnings and tax paid in the tax year.
Components of Final Pay
| Component | Calculation | Taxable? | Example (£30k salary) |
|---|---|---|---|
| Salary to leaving date | Monthly salary ÷ working days × days worked | Yes | £1,923 (for 15 days) |
| Accrued holiday | Unused days × daily rate | Yes | £577 (5 unused days) |
| Notice pay (if working) | Normal salary for notice period | Yes | £2,500 (1 month) |
| PILON (pay in lieu of notice) | Contractual: taxable. Non-contractual: first £30k tax-free | Varies | £2,500 |
| Redundancy (statutory) | Service × age factor × weekly pay (max £643/wk) | No (up to £30k) | Tax-free |
Holiday Accrual in Your Final Pay
Your holiday accrues at 1/12th of your annual entitlement per complete month worked. If you have taken fewer days than your accrued entitlement, the surplus is paid out. If you have taken more, your employer can deduct the excess from final pay (if your contract allows this).
For calculating your pro rata salary up to the leaving date, use the pro rata calculator. To check your holiday accrual, see our holiday pay calculator. For understanding your notice period obligations, check your employment contract or contact ACAS.

Worked Example: Final Pay When Leaving a Job Uk Calculator
Tom is leaving his job on 15 March with an annual salary of £28,000. His notice period ends mid-month.
Pro rata March salary: £28,000 ÷ 12 = £2,333 × (15 ÷ 31) = £1,129
Unused holiday pay: Tom has 8 unused days at a daily rate of £28,000 ÷ 260 = £107.69 per day = £862
Total final pay: £1,129 + £862 = £1,991 gross
Under UK law, your employer must pay all outstanding wages, unused holiday, and any contractual entitlements in your final payslip. Use our final pay when leaving a job uk calculator to check your figures.
Tips for Using This Calculator
- Always use gross salary: Enter the salary before tax and deductions — the final pay when leaving a job uk calculator works with gross figures.
- Check your contract: Your employment contract should state your full-time equivalent hours. Common UK standards are 35, 37, 37.5, and 40 hours per week.
- Know your rights: Under the Part-time Workers Regulations 2000, part-time employees must receive the same hourly rate, holiday entitlement (pro rata), and benefits as full-time colleagues.
- Tax personal allowance: For 2025/26, the first £12,570 of earnings is tax-free. If your pro rata salary falls below this, you pay no income tax at all.
- National Insurance: Employee NI is 8% on earnings between £12,570 and £50,270 (2025/26 rates). Check HMRC NI rates for the latest figures.
Pro Rata Holiday Entitlement
Under the Working Time Regulations 1998, all UK workers are entitled to a minimum of 5.6 weeks' paid holiday per year (28 days for full-time). If you work part-time, your entitlement is calculated pro rata based on your actual hours or days worked.
| Days Worked/Week | FTE Ratio | Statutory Days/Year | Bank Holidays (pro rata) |
|---|---|---|---|
| 5 days (full-time) | 1.0 | 28 days | 8 days |
| 4 days/week | 0.8 | 22.4 days | 6.4 days |
| 3 days/week | 0.6 | 16.8 days | 4.8 days |
| 2.5 days/week | 0.5 | 14 days | 4 days |
| 2 days/week | 0.4 | 11.2 days | 3.2 days |
Holiday entitlement is always rounded up — never down — when the result is not a whole number, per ACAS guidance on holiday entitlement. Bank holidays may be included in or added on top of your statutory 28 days, depending on your contract.
All calculations on this page follow ACAS pro rata pay guidelines and are consistent with the UK Employment Rights Act 1996. Tax figures use HMRC 2025/26 rates. The April 2025 National Living Wage of £12.21/hour is applied where relevant.
