Vacation Entitlement Calculator
Calculate your annual vacation entitlement for full-time or part-time work based on your working days per week, full-time vacation allowance and number of months worked in the year.
Calculate now
Use this vacation entitlement calculator to estimate annual vacation days for full-time and part-time work. It is especially useful when you want to convert vacation days to a model with fewer working days per week or when you only work part of the year. This gives you a practical first estimate for contracts, job changes and part-time models.
Vacation Entitlement Calculator: Estimate vacation entitlement transparently and fairly
Everyday calculators help make quick decisions more reliably. The right unit, period and base value are essential.
How to use the result better
- Clarify the base value first.
- Check unit and period: per day, month, year, net or gross.
- Calculate a second variant for plausibility.
Common mistake
Many errors come from swapped base values, mixed units or wrong periods. The result may look correct but answer the wrong question.
What to check next
Use related calculators if you want to put the result into money, time, percentages or deadlines.
Why is the unit so important?
A wrong unit or period immediately changes the result and can lead to wrong decisions.
How can I quickly check the result?
Calculate a second variant or estimate roughly in your head. Large differences become easier to spot.

How the result is calculated
Full-year entitlement for your model = full-time vacation days ÷ full-time working days per week × your working days per week\nVacation entitlement in the year = full-year entitlement × months worked ÷ 12\nMonthly entitlement = full-year entitlement ÷ 12
Worked example
Example: Your company grants 30 vacation days for full-time work based on 5 working days per week. If you work 3 days per week, the full-year entitlement becomes 18 days. If you only work 6 months in the year, the proportional vacation entitlement is 9 days.
When is a vacation entitlement calculator useful?
A vacation entitlement calculator is especially helpful for part-time work, job changes, new jobs, parental leave, temporary contracts or whenever the number of working days per week changes. Many users want to know how many vacation days they get with 2, 3 or 4 working days per week. That is exactly what this calculator is built for.
How does the part-time conversion work?
What matters is usually not the total hours per week but the number of working days per week. If full-time employees get 30 vacation days based on 5 days per week, that equals 6 vacation weeks. If you work 3 days per week, those 6 weeks remain the same, resulting in 18 vacation days.
Why do months worked matter?
If you do not work the full year, entitlement is often only proportional. That is why you can enter the number of months worked. This gives a more realistic estimate for mid-year starts or exits.
What this calculator does not cover
The calculator intentionally does not model every legal special case. This includes rounding rules, collective agreements, company-specific rules, waiting periods, carried-over vacation from previous years or special leave. Your actual contract remains the decisive source.
When is this calculator especially useful?
This calculator is especially useful when you want to understand vacation entitlement for part-time work, varying workdays or changes during the year. It is especially practical for quick comparisons across different work models.
How to use the result correctly
Use the calculator for quick orientation and for comparing different work models. For binding answers about entitlement, notice periods, carried-over vacation or special cases, always rely on your contract, HR department or professional advice.
How to interpret statutory minimum leave
Besides the contractual or company-specific vacation model, many users also want to understand the legal minimum. That is why this calculator additionally shows the mathematical minimum leave for your work model. This makes it easier to compare your actual entitlement with the legal baseline.
Frequently asked questions
How do I calculate vacation entitlement for part-time work?
What usually matters is your number of working days per week. This calculator converts vacation days from a full-time model proportionally to your own schedule.
Are hours or working days more important?
For the usual conversion of vacation entitlement, working days per week are typically more important than pure weekly hours.
Can I calculate only part of a year?
Yes. You can enter the months worked in the year so the calculator estimates a proportional entitlement.
Does this calculate statutory minimum vacation?
Not directly. You enter the number of full-time vacation days that apply in your company, whether statutory minimum or contractual entitlement.
Why is the result only an estimate?
Because contracts, collective agreements, rounding, carried-over vacation, special leave and other edge cases may matter in practice.
Is the result legally binding?
No. The calculator is for general information and first orientation only. Your contract, company rules and professional advice remain the relevant sources.
Why does the calculator also show vacation in weeks?
Many people compare work models more intuitively in vacation weeks rather than individual days. The additional weekly view helps make full-time and part-time entitlements easier to understand.
