Annual leave calculator western australia

Western Australia has a slightly different employment law landscape than the rest of the country, and annual leave is one of the places that bites people. Most WA employees are covered by the national Fair Work system and the National Employment Standards. But some — particularly those working under pre-reform state awards or in state government — are covered by WA state legislation instead. Knowing which system applies to you changes the rules, and sometimes the money.

Under the NES (which covers most WA private sector workers), full-time employees accrue four weeks of paid annual leave per year. Shift workers who regularly work on Sundays or public holidays are entitled to five weeks. Part-time employees get the same entitlement pro rata based on their contracted hours. Casual employees don’t get paid leave at all — they receive a 25% casual loading instead, which is meant to compensate.

This calculator handles both the four-week and five-week cases, includes the 17.5% leave loading where it applies, and gives you a payout estimate if your employment ends. The rates and rules are correct for NES-covered workers; if you’re on a WA state award, check your specific award conditions or contact Wageline WA.

The Accrual Maths, Worked Through

Annual leave accrues progressively, not in a lump at the start of the year. For a full-time employee working 38 hours a week on a 4-week entitlement, that’s 152 hours of leave per year, or roughly 2.923 hours per week.

The formula:

Annual leave accrued = (Days worked ÷ 365.25) × (Weeks’ entitlement × Weekly hours)

Say you started work on 01/07/2023 and you’re calculating your balance on 01/01/2024 — exactly 184 days later. Divide by 365.25 to get 0.5036 years. Multiply by 152 hours (4 weeks × 38 hours) and you get 76.5 hours accrued. If you’ve taken 38 hours of leave in that time, your balance is 38.5 hours — exactly one week’s pay at your hourly rate.

Leave Loading: Where It Comes From and Who Gets It

Annual leave loading of 17.5% is added on top of the ordinary pay rate when leave is taken or paid out on termination. It originated from the idea that employees on leave would miss out on overtime and other allowances they’d have earned if they were working. Not every WA employee gets it — it depends on your award or enterprise agreement. If your employment contract or award specifically includes it, the calculator adds it to your payout figure. If you’re unsure, check your Fair Work pay slip obligations or ask your employer for a copy of the applicable award.

A Real WA Scenario: Resignation After 26 Months

A hospitality worker in Perth earns $26.50 per hour for 38 hours per week. They resign after 2 years and 2 months (roughly 791 days). Their accrued leave is (791 ÷ 365.25) × 152 = 329.2 hours. They took 76 hours over that period, leaving a balance of 253.2 hours. Their award includes 17.5% loading. The base payout is 253.2 × $26.50 = $6,709.80. Loading adds $1,174.22. Total payout: $7,884.02 — paid out in the final pay run.

One detail that catches people out: leave continues to accrue during periods of paid annual leave itself. So if you take two weeks of leave, you keep accruing during those two weeks. Leave does not accrue during unpaid leave, generally speaking, unless your agreement says otherwise.

Practical Accuracy Tips

Use your actual employment start date from your contract or payslip, not an approximation. Even a month’s difference at a higher pay rate can shift the payout by hundreds of dollars.

If you’re part-time, enter your contracted ordinary hours — the hours specified in your contract, not what you actually worked in any given week. Annual leave accrues on contracted hours.

Ordinary pay rate means your base hourly rate, not your rate including allowances, shift penalties, or overtime. Leave loading (if applicable) is calculated on top of the ordinary rate only.

WA public holidays don’t reduce your leave balance — if a public holiday falls during a period of annual leave, you’re entitled to an extra day off or an extra day’s leave in lieu. This is a common source of disputes; Wageline WA outlines the rules in detail.

If you’re calculating leave accrual under a 40-hour week instead of 38, the annual leave calculator for 40-hour week employees on this site handles that variation specifically.

FAQs

How much annual leave do WA employees get?

Most full-time employees in Western Australia are entitled to four weeks of paid annual leave per year under the National Employment Standards. Shift workers who regularly work Sundays or public holidays are entitled to five weeks. Part-time employees receive the same entitlement on a pro rata basis based on their contracted hours.

Does annual leave accrue from day one in WA?

Yes. Under the NES, annual leave accrues progressively from the first day of employment. There’s no waiting period before leave starts accruing, though some awards specify a minimum service period before leave can be taken. Accrual and the right to take leave are two different things.

Can my employer refuse annual leave in WA?

Employers can decline an annual leave request on reasonable business grounds, but they can’t unreasonably refuse all requests. If your leave balance becomes excessive, an employer may also direct you to take leave (with sufficient notice) under the NES. Check your award or enterprise agreement for the specific notice requirements that apply in your case.

Is annual leave loading compulsory in WA?

Leave loading at 17.5% is not automatic for every WA employee. It applies if your award, enterprise agreement, or contract specifically includes it. If none of those documents mention leave loading, you’re not entitled to it by default. When in doubt, check the relevant award conditions on the Fair Work website or contact Wageline WA.

How is annual leave paid out on termination in WA?

When employment ends (resignation, redundancy, dismissal), any unused annual leave balance must be paid out at the ordinary rate of pay plus leave loading if applicable. This applies regardless of who terminated the employment. The payout is calculated on the hours accrued minus any leave taken, multiplied by the current hourly rate.

Does annual leave accrue on public holidays in WA?

Public holidays that fall on a day you would ordinarily work are paid as ordinary time and counted as service, so leave continues to accrue during that period. If a public holiday falls within a period of annual leave, the day is treated as a public holiday, not a leave day — meaning you don’t lose a leave day for it, and your leave balance should be adjusted accordingly.

Do casual employees in WA get annual leave?

No. Casual employees are not entitled to paid annual leave under the NES or WA state industrial laws. Instead, casual employees receive a loading (typically 25%) on their ordinary hourly rate, which is intended to compensate for the absence of leave and other entitlements. Some awards set this loading higher than 25% — check your specific award.

What is pro rata annual leave in WA?

Pro rata annual leave refers to the portion of leave entitlement earned for a partial year of service. Because leave accrues progressively, an employee who has worked six months has accrued half their annual entitlement. On termination, all accrued but untaken pro rata leave must be paid out at the applicable rate.
