Part-Time Job Holiday Entitlement Calculator
Use this quick calculator to estimate statutory holiday for part-time workers. It uses the standard 5.6 weeks per year method and can show your remaining balance after leave already taken.
Estimate based on UK statutory minimum entitlement. Company contracts may offer more generous leave.
How to Use This Part-Time Job Holiday Calculator
If you work part time, your annual leave is usually worked out on a pro-rata basis. In plain English: you get the same weeks of holiday as a full-time worker, but fewer total days because you work fewer days each week.
This calculator is designed to make that simple. Enter your weekly pattern, add how many months of the holiday year you have worked, and optionally subtract leave and bank holidays already used. You instantly get:
- Your annual entitlement in days
- Your pro-rata entitlement for the period worked
- The same entitlement expressed in hours
- Your remaining balance (days and hours)
Part-Time Holiday Entitlement Formula (UK)
Core rule
The standard statutory method is:
Days worked per week × 5.6 = annual holiday entitlement in days
For example, if you work 3 days per week:
- 3 × 5.6 = 16.8 days holiday per full year
If you have not worked the full holiday year, you can pro-rate that figure by months worked:
Annual entitlement × (months worked ÷ 12)
About the 28-day cap
Under UK statutory rules, full-time legal minimum is often presented as 28 days for a 5-day worker (including bank holidays where applicable). For employees working more than 5 days each week, statutory leave may still be capped at 28 days unless your contract says otherwise. This calculator applies that cap to the statutory result.
Why Days and Hours Both Matter
Some employers track leave in days, others in hours. If your shifts vary in length or your rota changes, hours can be easier and fairer to manage. That is why this tool also converts your entitlement to hours using your average hours per day.
Example: if your pro-rata entitlement is 10.5 days and your average day is 7.5 hours, your entitlement in hours is 78.75.
Worked Examples
Example 1: 2 days per week, full year
- Days per week: 2
- Annual entitlement: 2 × 5.6 = 11.2 days
- If already taken 3 days, remaining = 8.2 days
Example 2: 3.5 days per week, started mid-year
- Annual entitlement: 3.5 × 5.6 = 19.6 days
- Worked 6 months: 19.6 × 6/12 = 9.8 days
- Used 4 days total: remaining = 5.8 days
Example 3: Converting to hours
- Pro-rata days: 12.0
- Average shift length: 6 hours
- Total entitlement in hours: 72.0 hours
Common Mistakes People Make
- Forgetting bank holidays: In many workplaces, bank holidays come out of your holiday pot.
- Ignoring start date: New starters usually build entitlement through the year, not instantly at full-year level.
- Mixing days and hours: Make sure you compare like with like when checking your balance.
- Rounding too early: Keep decimals until the end for more accurate totals.
Frequently Asked Questions
Does this apply to zero-hour or irregular workers?
Irregular hours workers can require a different approach depending on contract type and current regulations. This calculator is best for predictable part-time schedules based on days worked per week.
Can my employer give more than this?
Yes. This tool estimates statutory minimum entitlement. Your employment contract may offer enhanced leave.
Is this legal advice?
No. It is an educational estimate tool. If your leave arrangement is complex, ask HR, payroll, your union representative, or a qualified employment adviser.
Final Takeaway
A part-time holiday calculator removes guesswork and helps you plan time off confidently. Use the result as a quick baseline, then compare it with your contract and company policy. A few minutes of checking now can prevent end-of-year surprises later.
