Proportional leave applies when employment does not cover the full year. It most often concerns a job change or starting the first job mid‑year.

When proportional leave applies

The proportional rule is used when:

  • the first job starts during the year,
  • the employee changes employers,
  • the contract covers only part of the year.

Each employer grants leave only for the actual period of employment.

How to calculate the proportion

The basic method is 1/12 of annual entitlement for each full month worked. Then you apply:

  • the proportion for working time,
  • rounding up partial days.

First job in the year

In the first year, leave accrues monthly. After completing the year, in the next calendar year leave is granted in advance.

Changing employers

When changing jobs, leave is split between employers. The new employer grants leave for the remaining period in the year, taking into account days already used.

Part‑time work and proportion

For part‑time employment, the entitlement is reduced proportionally. In practice, calculate the time proportion first and then apply the part‑time ratio.

Rounding leave days

Partial days are rounded up to a full day. This prevents under‑allocation of leave.

Practical scenarios

  • Job change mid‑year: the old employer grants leave for months worked, the new employer for the remaining part of the year.
  • First job from May: you accrue 1/12 of annual entitlement for each full month.

Checklist — step by step

  1. Determine annual entitlement (20 or 26 days).
  2. Count full months of employment in the year.
  3. Apply 1/12 for each month.
  4. If part‑time, apply the working‑time ratio.
  5. Round partial days up.

Example

An employee entitled to 26 days starts in July. For 6 months they get 13 days. With a 1/2‑time job, the entitlement becomes 7 days after rounding.

Quick timeline

  • Jan–Jun: no employment → no leave,
  • Jul–Dec: 6 months of work → 6/12 of annual entitlement.

Calculate in practice

Use the leave calculator to check proportional leave and cash equivalent.

Common mistakes

  • subtracting used leave before calculating the proportion,
  • rounding down partial days,
  • ignoring part‑time proportion,
  • forgetting the first‑year rule.
