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, with the arithmetic laid out so you can check your own payslip against it.

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, the National Employment Standards set the baseline: full-time employees accrue four weeks of paid annual leave per year of service, and that entitlement accrues progressively rather than arriving as a lump. Some shift workers are entitled to more, and awards or enterprise agreements can add to the baseline — check your award on the Fair Work website if you are unsure which rules cover you.

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.

A Worked Example: Leave in Hours

Payroll systems usually track leave in hours, not weeks, which is why the number on your payslip can look odd at first. The conversion is simple. Suppose Mia works a full-time 38-hour week. Four weeks of leave, expressed in her hours, is:

Spread across 52 weeks, that is 152 ÷ 52 ≈ 2.92 hours of leave accrued every week Mia works. After 20 weeks in the job she has roughly 20 × 2.92 ≈ 58.5 hours banked — about a week and a half of full-time leave. If her payslip shows a balance of 58 or 59 hours at that point, the payroll system is doing exactly what it should.

The same logic works in reverse. If you see 120 hours on your payslip and you work 38-hour weeks, you have 120 ÷ 38 ≈ 3.2 weeks of leave available — enough for a solid three-week break with a little left over.

Part-Time Leave Is Pro-Rata

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. Using the hours method: a part-timer on 19 hours per week accrues 4 × 19 = 76 hours of leave per year — still “four weeks” of leave, but four weeks of their working pattern, not a full-timer's.

Casual employment is treated differently. Casual employees generally do not accrue paid annual leave; instead they receive a higher hourly rate of pay (casual loading) in place of paid leave entitlements. The loading percentage depends on the award or agreement covering the role — check Fair Work for the rate that applies to you.

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.

Some employees are also entitled to annual leave loading — an extra percentage paid on top of ordinary pay while on leave. Loading is not universal: it depends on your award or enterprise agreement, and the percentage varies. If your payslip shows a “leave loading” line during a holiday, that is what it is; if you are unsure whether you are entitled to it, your award on the Fair Work website is the place to check.

One quirk worth knowing: if a public holiday falls during your annual leave, that day is generally treated as a public holiday rather than a day of leave — so it usually is not deducted from your leave balance. Take a two-week break over a period containing a public holiday and you will typically use nine days of leave, not ten.

What Happens to Unused Leave

If you do not use all your leave in a year, it does not vanish — annual leave carries over and continues to accumulate. This is why long-serving employees can build up sizeable balances.

When employment ends, accrued but untaken annual leave is paid out — you receive its cash value in your final pay. To make that concrete with an illustrative example: an employee leaving a job with 120 hours of unused leave at an ordinary rate of $35 an hour would receive 120 × $35 = $4,200 gross in their final pay, before tax. Unused annual leave is, in effect, money you have earned and not yet spent — though it is taxed when paid, and payouts on termination can be taxed differently from ordinary wages, so check current ATO guidance if a large payout is coming your way.

Some awards and agreements also allow cashing out a portion of annual leave while still employed — converting leave to pay without taking time off. Strict conditions apply, including a written agreement and limits on how much can be cashed out, and not every employee has this option. Check your award or agreement before assuming it is available.

Common Mistakes to Avoid

Assuming leave is use-it-or-lose-it. Annual leave in Australia carries over from year to year. Some workplaces have policies encouraging staff to reduce large balances, and awards can allow employers to direct the taking of excessive leave — but the balance itself does not expire at 30 June.

Reading a part-time balance in full-time weeks. A part-timer on 19-hour weeks with 76 hours banked has four weeks of leave, not two. Always divide your hour balance by your own weekly hours, not by 38.

Expecting leave loading automatically. Loading depends on your award or agreement. Budgeting a holiday around a loading payment you are not entitled to is a small but avoidable disappointment — confirm first.

Forgetting that unpaid periods usually do not accrue leave. Leave generally accrues on ordinary paid hours. Long stretches of unpaid leave typically pause accrual, which is worth factoring in if you are planning a career break.

Never checking the payslip balance. Payroll errors are rare but real. The weekly-accrual arithmetic above takes a minute to run — if your balance is drifting far from what the formula predicts, ask payroll to explain the difference.

Frequently Asked Questions

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 not lost if unused. Understanding the accrual — especially in hours, the way payroll sees it — makes it easy to plan time off and to spot any payslip errors early. Your leave balance is a real entitlement you have worked for; know what it is worth, and use it.
