Annual Leave Loading Calculator AU (17.5%)

Quick answer

This calculator estimates annual leave loading — the extra payment most modern awards add on top of ordinary base pay during paid annual leave. The formula is weeks of leave × weekly base pay × the loading rate, which is 17.5% under most awards. Whether loading applies to your award is set out by the Fair Work Ombudsman.

Item	Value
Standard loading rate	17.5% of ordinary base pay
Annual leave entitlement	4 weeks a year (5 weeks for eligible shift workers)
Part-time employees	Entitlement scales by FTE (e.g. 0.6 FTE = 2.4 weeks)
Casual employees	No loading — casual loading (typically 25%) is paid in lieu
Termination payout	Loading is payable if it would have been paid had the leave been taken

Three ways leave loading gets paid

This calculator estimates annual leave loading — the 17.5% extra payment most modern awards add on top of ordinary base pay while an employee is taking paid annual leave. It supports three modes:

• Take accrued leave during employment — work out the gross pay for a typical 4 weeks (or 5 weeks for shift workers), with FTE scaling for part-timers.
• Termination payout — the loading on accrued-but-untaken leave that is paid out in the final pay.
• Current accrued balance — a snapshot of what the loading would be at today's accrual.

It is built around the Fair Work Ombudsman annual leave loading guidance and the Fair Work final pay rules. It does not replace the actual modern award text — the award is the legally binding document.

Why the loading rate is 17.5% and how it is worked out

The standard rate of annual leave loading under most modern awards is 17.5% on ordinary base pay during periods of paid annual leave. The 17.5% figure comes from a 1970s industrial-relations settlement to compensate award-covered workers for lost overtime, shift penalties and other allowances during leave.

Loading amount = ordinary weekly pay × weeks of leave × FTE fraction × loading rate

Total pay = ordinary pay + loading

Key rules from Fair Work:

• The National Employment Standards give full-time and part-time employees 4 weeks of paid annual leave per year (5 weeks for some shift workers). Loading sits on top of that 4 weeks.
• For part-timers, weeks scale by the FTE fraction — a 0.6 FTE accrues 2.4 weeks/year.
• Casuals do not get loading. Their 25% casual loading is paid in lieu of paid annual leave entitlements.
• Some modern awards have removed loading and replaced it with higher ordinary rates — check the actual award.
• On termination, loading is generally paid on the accrued-leave payout when it would have been paid had the leave been taken during employment (Fair Work final pay).

Setting FTE, weeks of leave and the award toggle

• Mode — accrued leave taken during employment, termination payout, or pro-rata snapshot.
• Ordinary weekly pay (FTE rate) — the full-time-equivalent weekly base rate. The calculator scales by FTE for part-timers.
• Loading rate — defaults to 0.175 (17.5%). Set lower if your award uses a different figure.
• Weeks of leave per year — 4 for most, 5 for shift workers.
• FTE fraction — 1.0 = full-time, 0.6 = 0.6 FTE.
• Accrued leave balance — used in termination/pro-rata modes.
• Modern award includes loading — uncheck if your award has removed loading and baked it into base rates.
• Casual — zeroes out loading because casual loading is paid in lieu.

Loading worked through full-time, part-time, casual and termination cases

1. Full-time employee, $1,500/week, 4 weeks accrued. Ordinary pay = 4 × $1,500 = $6,000. Loading = 17.5% × $6,000 = $1,050. Total $7,050. This is the typical pre-tax figure on the payslip across the leave period.

2. Part-time 0.6 FTE on a $2,000/week FTE rate, takes the full annual entitlement. Weeks = 4 × 0.6 = 2.4. Effective weekly rate = $2,000 × 0.6 = $1,200. Ordinary pay = 2.4 × $1,200 = $2,880. Loading = $504. Total $3,384.

3. Termination payout: 6.5 weeks accrued at $1,200/week, award includes loading. Ordinary = 6.5 × $1,200 = $7,800. Loading = $1,365. Total $9,165 as the gross termination component for accrued leave. Note PAYG withholding on this component follows ATO Schedule 7, not the ordinary salary tables.

4. Casual on $40/hour ordinary rate. Loading = $0 because the 25% casual loading already in the hourly rate is paid in lieu of paid annual leave entitlements. The hypothetical ordinary pay still calculates so payroll can sanity-check.

5. Modern award has removed loading. Even with 4 weeks accrued at $1,500/week, loading = $0 — the 17.5% has been folded into the higher ordinary rate already paid every week, so taking leave produces the same weekly amount as working.

Mistakes that distort the loading figure

• Using the part-time weekly rate but the full-time accrual. Either scale weeks by FTE, or use the FTE weekly rate and let the FTE input do the scaling — don't do both.
• Assuming casuals get loading. They do not. Their 25% casual loading is the in-lieu payment.
• Forgetting to check the award text. A handful of modern awards have removed loading. Fair Work's pay tool and the award PDF on fairwork.gov.au are the source of truth.
• Mis-taxing loading on termination. Loading paid during employment is ordinary PAYG. Loading paid on termination follows ATO Schedule 7 — the rate differs (and may be a flat rate for genuine redundancy).
• Using base hourly rate when the award uses a higher figure for loading purposes. Some awards include certain allowances in the loading base. Read the clause carefully.
