How Much Annual Leave Per Week Should Employees Accrue In Australia?

Getting annual leave accrual right is one of those small payroll details that has big compliance consequences. If you’re running a team in Australia, you need a clear, consistent method for calculating how much annual leave employees accrue each week, and how that plays out for full-time, part-time, shiftworkers and staff with variable hours.

In this guide, we’ll break down the law in plain English, show you simple formulas that work in practice, and walk through common edge cases. We’ll also flag where policies and contracts help you stay consistent and compliant as you grow.

Let’s make this straightforward so your business can run smoothly - and confidently - week to week.

What Does The Law Say About Annual Leave Accrual In Australia?

Under the National Employment Standards (NES) in the Fair Work Act 2009 (Cth), most employees (other than casuals) are entitled to paid annual leave that accrues progressively during the year based on their ordinary hours of work and accumulates year to year.

• Full-time and part-time employees accrue the equivalent of 4 weeks of paid annual leave for each year of service (pro‑rated for part-time).
• Shiftworkers (as defined by the applicable award or agreement) may be entitled to 5 weeks per year.
• Casual employees don’t accrue paid annual leave.

Accrual happens on ordinary hours worked and continues while an employee is on paid leave (e.g. paid annual leave, paid personal/carer’s leave). It generally does not accrue during unpaid leave (for example, unpaid parental leave). Workers compensation periods can be more complex and may depend on the applicable state or territory law and any award or enterprise agreement - if this applies to your team, it’s best to get tailored advice.

Your contracts and policies should align with these minimum standards and any applicable modern award or enterprise agreement. It’s smart to lock this in from day one with a clear, compliant Employment Contract and leave-related policies in your staff handbook.

How Much Annual Leave Do Employees Accrue Per Week?

There are two simple ways to think about weekly accrual. Both get you to the same place; use whichever is easier in your payroll system.

Method A: Hours-Per-Week ÷ 52

Employees accrue four “weeks’ worth” of their ordinary hours across the year (or five weeks for certain shiftworkers). To get a weekly rate, take the annual entitlement in hours and divide by 52.

• Full-time (38-hour week, 4 weeks per year): 38 × 4 = 152 hours per year. Weekly accrual = 152 ÷ 52 = 2.923 hours per week.
• Shiftworker (38-hour week, 5 weeks per year): 38 × 5 = 190 hours per year. Weekly accrual = 190 ÷ 52 = 3.654 hours per week.
• Part-time (e.g. 20 hours per week, 4 weeks per year): 20 × 4 = 80 hours per year. Weekly accrual = 80 ÷ 52 = 1.538 hours per week.

Method B: Per-Hour Accrual Rate

Alternatively, use a per-hour rate and multiply by ordinary hours worked in the week. This is handy for variable rosters.

• 4-week entitlement rate: 4 ÷ 52 = 0.076923 hours of annual leave per ordinary hour worked.
• 5-week entitlement rate: 5 ÷ 52 = 0.096154 hours of annual leave per ordinary hour worked.

For example, if a part-time employee works 24 ordinary hours this week and is entitled to 4 weeks per year, weekly accrual = 24 × 0.076923 = 1.846 hours.

Either approach is fine - just be consistent, make sure it matches any award rules that apply, and ensure your payroll software calculates on ordinary time, not overtime.

Weekly Accrual Examples (Full-Time, Part-Time, Shiftworkers and Variable Hours)

Full-Time Employees (38-Hour Week)

• 4-week entitlement: 2.923 hours annual leave accrued per week (≈ 152 hours per year).
• 5-week shiftworker entitlement: 3.654 hours per week (≈ 190 hours per year).

Tip: Many awards classify “shiftworker” narrowly. Check the applicable award/enterprise agreement to confirm eligibility for 5 weeks.

Part-Time Employees

Part-time staff accrue leave based on their ordinary hours. Use either:

• Annual hours = ordinary weekly hours × 4 (or 5 for shiftworkers); then ÷ 52 for weekly accrual, or
• Per-hour accrual rate (0.076923 for 4 weeks) × ordinary hours worked in the week.

Example: 25-hour/week employee with a 4-week entitlement accrues 25 × 0.076923 = 1.923 hours in a week they work their usual hours.

Irregular or Variable Hours

If weekly hours vary, apply the per-hour accrual rate to the ordinary hours actually worked each pay period. This ensures accrual tracks the hours worked and stays compliant.

Overtime, Paid Leave and Unpaid Leave

• Overtime: Annual leave accrues on ordinary hours only (not overtime), unless an award or enterprise agreement says otherwise.
• Paid leave: Accrual continues while an employee is on paid annual leave or paid personal/carer’s leave.
• Unpaid leave: Generally, annual leave does not accrue during periods of unpaid leave (including unpaid parental leave).

If your team uses TOIL (time off in lieu) arrangements, ensure you’ve set clear rules in writing and that your payroll treats TOIL correctly - Time Off In Lieu arrangements should always mirror award or agreement requirements.

How Many Days Is “4 Weeks Annual Leave” In Practice?

The NES talks in weeks, but payroll often needs days and hours. The safest approach is to convert weeks into the employee’s ordinary hours and deduct leave in hours, not days, so it fairly reflects varying shift lengths.

For employees working a standard 5‑day week, “4 weeks” typically equals 20 working days per year (or 152 hours for a 38‑hour week). For part-time staff, 4 weeks equals four times their normal working week - for example, 4 weeks × 3 days/week = 12 working days per year.

If you manage leave by hours across your business, you’ll avoid over‑ or under‑deducting when someone works longer (or shorter) shifts on different days.

Setting Up Payroll, Policies And Contracts To Get Leave Right

The maths is one part; building a simple, compliant framework is what keeps your business consistent and fair.

1) Lock In The Rules In Your Contracts And Handbook

Set expectations in your Employment Contract and staff handbook (for example, when and how to request leave, how leave is deducted, and what documentation you require). A clear policy helps your payroll team apply the same approach for everyone and reduces disputes.

If you don’t have a handbook yet, consider rolling key policies (leave, rostering, breaks, grievance process) into a practical workplace policy suite that matches your award coverage and business operations.

2) Configure Payroll Software Carefully

• Choose one accrual method (weekly hours ÷ 52, or per-hour rate) and stick to it.
• Ensure accrual applies to ordinary hours only and continues on paid leave types, but not on unpaid leave.
• Use hours-based leave balances to handle variable shift lengths consistently.

It’s also good practice to show leave balances on payslips or in your employee self-service portal (even if not strictly required) - transparency goes a long way to avoiding confusion.

3) Keep An Eye On Awards And Agreements

Most of the time, the NES minimums cover annual leave, but many modern awards include extra conditions (e.g. additional week for specific shiftworkers, shutdown provisions, closedown directions, etc.). Make sure your settings reflect the award(s) that apply to your staff.

4) Plan For Common Scenarios - Cashing Out, Loading & Termination

• Cashing out annual leave: Only permitted in limited circumstances and with safeguards; awards often impose extra rules. It’s wise to document your process and read up on cashing out annual leave before saying yes.
• Annual leave loading: Many awards require a loading (often 17.5%) when leave is taken. If a loading applies to your team, build it into your payroll and understand the rules - see annual leave loading.
• Final pay: Unused annual leave must be paid out on termination at the correct rate (and include loading if required). If you’re unsure about inclusions, check your obligations around calculating final pay.

Finally, if your business provides above-award benefits, make sure those “better off overall” arrangements are captured in writing and applied consistently.

Annual Leave Accrual FAQs For Employers

How many hours of annual leave per week should a full-time employee accrue?

For a 38-hour full-time employee with a 4-week entitlement, the typical weekly accrual is 2.923 hours. For a qualifying shiftworker with a 5‑week entitlement, it’s 3.654 hours.

How do I calculate weekly accrual for part-time employees?

Use the same formula, based on their ordinary hours. Either multiply weekly ordinary hours by 4 (or 5) and divide by 52, or apply the per-hour accrual rate (0.076923 for 4 weeks; 0.096154 for 5 weeks) to the ordinary hours worked in the period.

Does annual leave accrue on overtime?

Generally no - annual leave accrues on ordinary hours only, unless an award or enterprise agreement says otherwise.

Do casuals accrue paid annual leave?

No, casual employees do not accrue paid annual leave under the NES.

What happens to unused annual leave when employment ends?

Unused annual leave must be paid out at termination at the correct rate. If a loading would have applied when leave was taken under an award, it typically applies to the payout as well. For broader context on leave and termination, see annual leave payments.

Can I require employees to take annual leave during a shutdown?

Some awards and agreements include shutdown provisions that allow this with proper notice and process. Check your award conditions and set expectations in your policies and contracts so your approach is consistent.

Putting It All Together: A Simple Accrual Playbook

If you’re setting this up for the first time, here’s a straightforward approach that keeps you aligned with the law and your award obligations:

1. Confirm each role’s classification, award coverage and whether the 4‑week or 5‑week entitlement applies.
2. Choose a calculation method (weekly hours ÷ 52 or per‑hour rate) and apply it to ordinary hours only.
3. Use hours-based leave balances in payroll to handle different shift lengths fairly.
4. Document your rules in an Employment Contract and staff handbook, including how requests, approvals and deductions work.
5. Build in controls for edge cases (cashing out, shutdowns, leave loading) and keep them consistent with the award - a short policy note will save headaches later.
6. Review at least yearly, especially if you change awards, move to shiftwork patterns or adopt TOIL - keep your processes aligned with loading, cashing out rules and final pay obligations.

As your team grows, you’ll also want your employment documents to keep pace - if you’re offering new benefits, changing rosters, or shifting pay structures, align your paperwork. Where equity or long-term incentives are on the table, consider whether separate agreements (like an ESOP) need to sit alongside your contracts.

For context outside annual leave, some businesses also choose to offer or manage compensating time via TOIL. Make sure any TOIL arrangement complies with the relevant award or agreement and is clearly documented.

Key Takeaways

• Under the NES, non‑casual employees accrue paid annual leave progressively based on ordinary hours - typically 4 weeks per year (5 weeks for certain shiftworkers).
• A practical weekly accrual for a 38‑hour full‑time employee is 2.923 hours (or 3.654 hours for 5‑week shiftworkers). The per‑hour accrual rate is 0.076923 (4 weeks) or 0.096154 (5 weeks).
• Part‑time and variable‑hours employees accrue leave pro‑rata based on ordinary hours, so hours-based balances are the fairest way to manage deductions across different shift lengths.
• Accrual continues on paid leave (e.g. paid annual leave, paid personal/carer’s leave) but generally not during unpaid leave. Overtime doesn’t usually accrue annual leave.
• Get the framework right: configure payroll carefully, embed the rules in your Employment Contract and workplace policies, and keep an eye on award conditions (loading, cashing out, shutdowns, final pay).
• When in doubt (especially with awards, shiftworker definitions or workers compensation scenarios), it’s best to get tailored legal advice before setting or changing your accrual rules.
