Expert Guide: How to Calculate Payment in Lieu of Holiday in the UK
When employment ends, one of the most common payroll questions is this: how much should be paid for untaken annual leave? In UK employment law and payroll practice, this is often called payment in lieu of holiday or payment for accrued but untaken leave. Getting this right is important for both employees and employers. Workers want confidence they are receiving their legal entitlement, while employers need to avoid underpayment claims, payroll errors, and compliance risk.
This guide explains the practical method behind a payment in lieu of holiday calculator UK, including statutory entitlement, accrual logic, common formulas, and final pay statement checks. It is designed to be useful for HR teams, small business owners, agency workers, fixed term staff, and employees trying to sense check a final payslip.
What is payment in lieu of holiday?
Payment in lieu of holiday means a cash payment for holiday that was earned but not used before employment ended. In normal ongoing employment, statutory holiday should usually be taken as time off. At termination, however, any outstanding entitlement must generally be settled financially through payroll.
The amount depends on two core components:
- How much leave was accrued up to the leaving date.
- The worker’s holiday pay rate used to value that leave in pounds.
If someone has taken more leave than they accrued, there can be an overuse position. Whether deductions are made depends on contract wording and payroll policy, so employers should review contract terms carefully before making deductions.
Statutory annual leave rules in the UK
Under UK rules, most workers are entitled to 5.6 weeks of paid annual leave each leave year. For someone who works 5 days per week, this is 28 days. For part-time workers, entitlement is pro-rated according to their working week.
| Working pattern | Statutory entitlement formula | Annual entitlement result |
|---|---|---|
| 5 days per week | 5.6 × 5 | 28.0 days (statutory cap reached) |
| 4 days per week | 5.6 × 4 | 22.4 days |
| 3 days per week | 5.6 × 3 | 16.8 days |
| 2.5 days per week | 5.6 × 2.5 | 14.0 days |
Some employers provide contractual leave above statutory minimum, and that extra leave may have separate rules. A robust calculator should allow a custom annual entitlement input so that both statutory only and enhanced contractual packages can be modelled correctly.
Accrual method used in a payment in lieu calculation
For many regular workers, holiday accrues over the leave year. A common practical formula is:
Accrued leave (days) = annual entitlement (days) × months worked ÷ 12
This is a clean estimate used by payroll teams for planning and early checks. Exact methods can vary based on contract wording and company policy, especially where accrual is tracked daily or hourly in an HR system.
For irregular or part-year workers, UK reforms allow accrual methods linked to hours worked, often using 12.07% in applicable cases for leave years beginning on or after the relevant implementation date. In those cases, calculators may estimate holiday hours first, then convert into days using average hours per day.
Holiday pay rate: why weekly pay matters
Accrued days are only half of the calculation. You also need the value per day. For salaried staff with fixed schedules, payroll teams often derive daily value from weekly pay and days worked per week:
Weekly pay = annual salary ÷ 52
Daily rate = weekly pay ÷ working days per week
For hourly-paid workers, a standard estimate is:
Weekly pay = hourly rate × weekly hours
Daily rate = weekly pay ÷ working days per week
Where pay is variable, holiday pay law uses reference periods, and many employers use a 52 paid-week approach for average weekly pay. That is why premium calculators often include an optional 52-week average pay field for irregular workers.
| Calculation element | Regular hours worker | Irregular or part-year worker |
|---|---|---|
| Accrual basis | Pro-rata through leave year | Often 12.07% of hours worked where applicable |
| Pay reference | Fixed salary or stable weekly pay | Average pay, commonly using 52 paid weeks |
| Output | Outstanding days × day rate | Outstanding days or hours converted to value |
| Main risk area | Using wrong leave year dates | Ignoring variable pay history |
Step by step method for employees and employers
- Identify the holiday year start and end dates used by the contract.
- Calculate accrual up to leaving date using the relevant method.
- Subtract leave already taken to find remaining entitlement.
- Calculate correct daily value from salary, hourly pay, or average weekly pay.
- Multiply remaining days by daily value to get payment due.
- Check final payslip tax and National Insurance treatment through payroll.
Worked example
Suppose a worker has a salary of £32,000, works 5 days per week, receives 28 days annual leave, has worked 8 months of the leave year, and has taken 10 days so far.
- Accrued leave = 28 × 8 ÷ 12 = 18.67 days
- Remaining leave = 18.67 – 10 = 8.67 days
- Weekly pay = £32,000 ÷ 52 = £615.38
- Daily rate = £615.38 ÷ 5 = £123.08
- Payment in lieu = 8.67 × £123.08 = about £1,066.08
That is the core logic used by the calculator on this page. Real payroll results may differ slightly due to exact leave accrual rules, rounding policy, and enhanced contractual terms.
Common mistakes that cause disputes
- Using calendar year instead of the contractual leave year.
- Applying full annual entitlement rather than pro-rated accrual to leaving date.
- Forgetting to account for leave already taken and approved in HR systems.
- Using basic pay only where average pay rules should include variable elements.
- Ignoring part-time schedule changes during the year.
- Rounding too early in the calculation, creating final pay differences.
How this calculator is best used
Use this calculator for a fast, transparent estimate before final payroll is run. It is especially useful for:
- Employees checking if their final holiday payment seems reasonable.
- Managers planning resignation or redundancy costs.
- HR and payroll administrators preparing termination paperwork.
- Recruiters and agency coordinators handling short assignments.
For formal payroll processing, always reconcile against your internal records and legal guidance, including the worker’s contract and current statutory rules.

Frequently asked practical questions
Does payment in lieu of holiday include bank holidays?
It depends on how the contract structures entitlement. Some contracts include bank holidays inside the annual total, while others provide them separately.
Can an employer refuse to pay untaken statutory leave when someone resigns?
Statutory accrued but untaken leave is generally payable on termination. Disputes usually concern amount, not principle.
What if I took too much holiday before leaving?
Potential deductions can arise, but only where contract terms support this and payroll handling is lawful and transparent.
Should overtime or commission affect holiday pay?
In many situations, normal remuneration principles and average pay rules mean variable earnings can matter. If your pay fluctuates, use the average weekly pay approach and check current legal guidance.
