How Annual Leave Accrues and Is Paid
Paid annual leave does not arrive all at once — it builds up gradually as you work. Here is how accrual works and what happens to leave you do not use.
Annual leave is one of the most valuable parts of paid employment, yet many people are unsure exactly how it works — how it builds up, how it is paid, and what happens to it if they do not take it. This guide explains the mechanics of annual leave in plain terms.
Leave Accrues Gradually
The key idea is accrual. You do not receive a full year's leave on day one. Instead, leave builds up steadily as you work — a small amount with every pay period — until you have accumulated enough to take time off.
In Australia, for example, full-time employees typically accrue four weeks of paid annual leave per year of service. That four weeks does not appear all at once; it accumulates progressively across the year. Different countries and some roles have different entitlements, but the gradual-accrual principle is widespread.
How the Accrual Adds Up
If a full-time year of work earns four weeks of leave, you can think of it as building toward that total bit by bit. Roughly speaking, each block of work earns a proportional slice of leave:
So after working half a year full-time, you would have accrued about two weeks of leave; after three months, about one week. Payroll systems track this precisely and usually display your current balance on your payslip.

Part-time employees also receive paid annual leave — calculated pro-rata, meaning in proportion to the hours they work. Someone working half the hours of a full-time role accrues leave at half the rate. The entitlement is the same idea, simply scaled to the hours worked. Casual employment is often treated differently, sometimes with a higher hourly rate in place of paid leave.
How Annual Leave Is Paid
When you take annual leave, you are generally paid as if you had worked — your ordinary pay continues during your time off. This is the whole point of paid leave: you can rest or travel without losing income. In some systems, additional amounts such as leave loading may apply on top, depending on the rules covering your employment.
What Happens to Unused Leave
If you do not use all your leave in a year, in many systems it does not simply vanish — it typically carries over and continues to accumulate. This is why long-serving employees can build up sizeable balances.
And when employment ends, accrued but untaken annual leave is usually paid out — you receive its cash value in your final pay. Unused annual leave is, in effect, money you have earned and not yet spent.
Frequently Asked Questions
Do I get all my annual leave at the start of the year?
Generally no. Leave accrues gradually as you work, building up across the year rather than arriving all at once.
Do part-time workers get annual leave?
Yes — usually on a pro-rata basis, in proportion to the hours they work. Casual roles are often handled differently.
What happens to leave I do not use?
In many systems it carries over and keeps accruing, and any accrued leave is typically paid out when employment ends.
Annual leave is pay you earn slowly: it accrues with every pay period, scales pro-rata for part-time work, is paid at your ordinary rate when taken, and is generally not lost if unused. Understanding the accrual makes it easy to plan time off — and to see your leave balance for what it is, a real entitlement you have worked for.
