accrual_rate / 52 * weeks_worked * (work_days_per_week / 5)Frequently asked questions
How is the accrual calculated?
The annual rate is divided by 52 weeks, then multiplied by the weeks worked and adjusted for your work schedule (days per week divided by 5).
What if I work part-time?
The calculator adjusts the accrual proportionally based on your working days per week. For example, working 3 days a week accrues 60% of the full-time rate.
Does this include public holidays?
No, this calculator only estimates vacation days accrued. Public holidays are typically separate from vacation entitlement.

Formulas
The math behind this calculator, written out so you can verify the result.
Accrual formula
This formula prorates the annual vacation allowance based on the number of weeks worked and the proportion of a full-time schedule.
Example:
Input: Annual rate = 20, weeks worked = 26, days per week = 5
Calculation: (20/52) × 26 × (5/5) = 10
Result: 10 days
Real-world use cases
Where this calculation shows up in everyday life.
Track accrued leave
Employees can estimate how much vacation time they have earned mid-year.
Example: After 6 months at 20 days/year, you have about 10 days.
Plan time off
Plan vacations by knowing how many days you'll have accrued by a future date.
Example: If you work 4 days/week, you accrue slower.
Compare job offers
Compare vacation benefits between jobs with different accrual rates and schedules.
Example: A 25-day job vs a 20-day job.
Tips and common mistakes
Tips
- Check your company's policy for rounding rules.
- Accrual may be capped at a maximum balance.
- Some companies accrue monthly, not weekly; adjust weeks accordingly.
- Use this as an estimate, not a legal document.
Common Mistakes to Avoid
- Forgetting to adjust for part-time schedules.
- Using months instead of weeks without converting.
- Assuming accrual starts immediately; some companies have a probation period.
Assumptions and limitations
- Use the stated inputs and units.
- Results are estimates for planning and education.
- Check measurements and source data before making an important decision.
