Holiday Pay Calculator
Estimate your accrued holiday entitlement and the value of holiday pay based on your pay rate and time worked.
This tool provides an estimate only and does not replace payroll, HR policy, or legal advice.
What this holiday pay calculator helps you do
Holiday pay can feel simple until you try to calculate it across irregular schedules, part-time contracts, overtime, commission, and partial-year work. This calculator is built to give you a practical estimate quickly, without spreadsheets.
It helps you answer common questions:
- How many holiday hours have I accrued so far?
- What is the cash value of that holiday entitlement?
- How much holiday pay remains after time already taken?
- What happens when regular overtime or commission is included?
How the calculation works
1) Accrual rate method
This method estimates entitlement from total hours worked. The formula used is:
Holiday hours = Average hours per week × Weeks worked × (Accrual rate ÷ 100)
It is often used where hours vary or where leave is tracked proportionally across shifts.
2) Statutory weeks pro-rata method
This method starts from annual entitlement in weeks (for example, 5.6 weeks) and prorates it for the period worked:
Holiday hours = Average hours per week × Statutory weeks × (Weeks worked ÷ 52)
It is useful for annualized leave policies and standard contracts.
3) Effective holiday pay rate
Where regular extras (such as normal overtime or commission) should be included, the calculator adds those in a simplified way:
Effective hourly rate = Base hourly rate + (Average additional weekly pay ÷ Average weekly hours)
The total pay value is then:
Total holiday pay = Holiday hours × Effective hourly rate
Step-by-step: using the calculator
- Choose your currency and method.
- Enter your base hourly rate and average weekly hours.
- Enter how many weeks were worked in the period.
- Enter either accrual rate or statutory weeks (depending on method).
- Add any regular weekly extras if applicable.
- Add holiday hours already paid/taken to see what remains.
Worked examples
Example A: hourly worker with accrual rate
If someone earns £15/hour, works 30 hours/week for 20 weeks, and accrues holiday at 12.07%, the estimated holiday hours are:
30 × 20 × 12.07% = 72.42 hours
If they have already taken 20 hours, remaining entitlement is 52.42 hours.
Example B: pro-rata statutory approach
A worker averaging 37.5 hours/week and entitled to 5.6 weeks/year, after 26 weeks worked:
37.5 × 5.6 × (26/52) = 105.0 hours
At $22/hour, this corresponds to about $2,310 in holiday pay value before deductions and payroll treatment.
Common mistakes to avoid
- Using contracted hours instead of average actual hours when schedules vary.
- Ignoring regular overtime/commission where policy or law includes it in holiday pay.
- Mixing days and hours without a clear conversion (use average hours per workday).
- Forgetting already-used leave, which inflates remaining entitlement.
- Assuming one rule applies everywhere; jurisdiction and contract terms matter.
Holiday pay policy checks for employers and employees
Before finalizing payroll or budgeting leave, verify the following:
- Your contract’s annual leave basis (days, weeks, or hours).
- The defined leave year and how partial-year service is handled.
- How overtime, shift premium, and commission are treated.
- Rules around carry-over, unpaid leave, and termination payouts.
- Local statutory requirements and collective agreements.
Final takeaway
A good holiday pay estimate helps both workers and managers plan confidently. Use this calculator as a reliable first pass, then align the result with your payroll rules and legal framework. If your situation includes variable shifts, parental leave, sick leave, or complex bonus structures, treat the result as a guide and confirm the final figure with HR or payroll.
