Annual leave calculator 40 hour week australia

Plenty of Australian workers do 40 hours a week, but the National Employment Standards were written around a 38-hour ordinary week. That two-hour gap trips up payroll teams, HR software, and employees doing their own sums all the time. The resulting undercalculations — usually a few hundred dollars per employee — tend to surface at termination, when the payout figure doesn’t match the employee’s own tally and a Fair Work dispute follows.

The short version: your annual leave entitlement is four weeks of your ordinary hours. If 40 is your ordinary weekly figure, you get 160 hours of leave per year, not 152. And your leave accrual rate is 160 ÷ 2,080 ordinary hours in the year — about 0.0769 hours of leave for every ordinary hour worked.

This calculator handles all of that automatically. Punch in your actual hours, pay rate, and any leave you’ve already taken, and it shows you accrued hours, balance in days and weeks, accrual per week, and an estimated payout value including the 17.5% leave loading where it applies.

How the Maths Works Behind the Calculator

The Core Formula

Annual leave entitlement for a full year is straightforward once you know your ordinary hours:

Full-year leave (hours) = leave weeks × ordinary hours per week

For a standard 40-hour employee on 4 weeks’ leave: 4 × 40 = 160 hours per year.

Accrual works proportionally over the weeks employed:

Accrued leave = (full-year leave hours ÷ 52) × weeks employed

So someone 26 weeks into a job: (160 ÷ 52) × 26 = 80 hours accrued.

Converting Hours to Days

One leave day equals your ordinary hours divided by 5. At 40 hours, that’s 8 hours per day. So 80 hours ÷ 8 = 10 leave days, or 2 weeks. Clean.

The Leave Loading Component

Where it applies (check your award or enterprise agreement), 17.5% loading sits on top of the base leave pay. For 80 hours at $35.00/hr:

• Base leave pay: 80 × $35.00 = $2,800.00
• Loading: $2,800.00 × 0.175 = $490.00
• Total payout: $3,290.00

Not every award includes loading. Some enterprise agreements pay the higher of loading or the employee’s ordinary-time earnings — in that case you’d need to compare figures manually. The Fair Work Ombudsman’s annual leave page has the authoritative breakdown by award category.

Real Scenario: 40 Hours, Mid-Year Resignation

The Situation

Anita works 40 ordinary hours a week in a Melbourne warehouse. She’s covered by a modern award that includes 17.5% leave loading. She resigns after 38 weeks and has taken 16 hours of leave during that time. Her ordinary hourly rate is $29.50.

Step by Step

Full-year entitlement: 4 × 40 = 160 hours

Accrued over 38 weeks: (160 ÷ 52) × 38 = 116.92 hours

Balance after leave taken: 116.92 − 16 = 100.92 hours

Balance in days: 100.92 ÷ 8 = 12.6 days

Base leave payout: 100.92 × $29.50 = $2,977.14

Loading (17.5%): $2,977.14 × 0.175 = $520.99

Total leave payout on termination: $3,498.13

Worth knowing: leave loading is payable on termination in most (but not all) awards. One specifically odd quirk — under the Hair and Beauty Industry Award, loading is only payable when leave is actually taken, not on termination. Always verify with the specific award.

What Shift Workers Get Instead

Shift workers under the NES who regularly work on Sundays and public holidays are entitled to 5 weeks of annual leave rather than 4. At 40 hours that’s 200 hours per year, and the accrual rate climbs to roughly 3.846 hours per week. The calculator’s leave type dropdown handles this — just select “Shift worker (5 weeks / year)” and the figures update accordingly.

Things That Catch People Out

Ordinary Hours vs Total Hours

Leave accrues on ordinary hours only. Overtime doesn’t generate leave entitlement. If someone’s contracted to 40 hours but regularly does 45, the five extra hours are overtime — they don’t add to the leave balance. This is the most common source of inflated leave expectations.

Part-Year Accrual

Leave accrues continuously from the first day of employment. There’s no qualifying period for accrual under the NES, though an employer can require that the employee complete 12 months before they can access leave for the first time (unless the employment ends before that point, in which case the accrued amount is paid out). See the Fair Work accrual rules for the precise wording.

Casual Employees

Casuals don’t accrue annual leave. Their 25% casual loading is meant to compensate for leave and other entitlements. If you’re unsure whether your arrangement is truly casual or effectively permanent, Fair Work’s guidance on casual conversion is the place to start.

Pro Rata at Termination

Whether leave is terminated voluntarily or involuntarily, any accrued unused balance must be paid out at the employee’s base pay rate plus applicable loading. Withholding it isn’t legal. If you’re calculating your own expected payout before handing in notice, this calculator gives you a solid figure to check against your final payslip. You might also find the annual leave calculator for 38-hour week workers useful if your contracted hours differ.

Award vs NES

The NES sets a floor — 4 weeks for non-shift, 5 for shift. Awards and enterprise agreements can grant more, never less. If your award says 5 weeks for all employees, use 5 in the calculator regardless of shift patterns.

FAQs

Is annual leave for a 40-hour week 160 or 152 hours?

It’s 160 hours. The NES entitlement is 4 weeks of your ordinary hours, so 4 × 40 = 160. The 152-hour figure only applies to employees on a 38-hour ordinary week. Using 152 for a 40-hour worker results in underpayment.

How much annual leave do I accrue per week on a 40-hour week?

On a standard 4-week entitlement, you accrue 160 ÷ 52 = 3.077 hours of leave per week. Over a fortnight that’s about 6.15 hours, which is what most payslips show in the leave accrual column.

Does the 17.5% annual leave loading apply to all 40-hour week workers?

No. Loading applies where it’s specified in your award or enterprise agreement. Check your specific award on the Fair Work website. Where loading does apply, it’s calculated on the base rate of pay for the leave period — not on penalties, overtime, or allowances.

What happens to my accrued leave if I’m made redundant?

It must be paid out in full on your final payslip, calculated at your ordinary time rate plus any applicable leave loading. Redundancy doesn’t extinguish the entitlement — it crystallises it as a cash payment. The ATO treats this component as ordinary income for tax purposes in the year of payment.

Can my employer make me take annual leave?

Yes, in certain circumstances. Most modern awards allow employers to direct employees to take leave when a business shuts down (like over Christmas), provided reasonable notice is given. Some awards also allow direction to take leave when the balance exceeds a threshold — often 8 weeks. Your specific award will spell out the notice requirements.

How do I convert my leave balance from hours to weeks?

Divide your balance in hours by your ordinary hours per week. At 40 hours: 80 hours ÷ 40 = 2 weeks. To convert to days, divide by your ordinary hours per day (usually 40 ÷ 5 = 8 hours per day), so 80 ÷ 8 = 10 days.

Does overtime count toward annual leave accrual?

No. Leave accrues on ordinary hours only. Whether overtime is worked occasionally or regularly, it doesn’t generate additional leave entitlement under the NES. Some enterprise agreements have more generous provisions — if yours does, the agreement document will say so explicitly.

What’s the difference between annual leave accrual for 38-hour and 40-hour workers?

The accrual rate as a proportion of hours worked is identical — both are 4 weeks out of 52. But because the 40-hour worker has more ordinary hours per week, their leave balance grows faster in absolute terms: 3.077 hours per week versus 2.923 for a 38-hour worker. Over a full year, that’s a 160-hour entitlement versus 152 hours. For a precise comparison, try the 38-hour week leave calculator side by side with this one.

Is my annual leave payout taxable?

Yes. Leave paid out during employment (when you’re taking leave) is taxed as ordinary income at your marginal rate. Leave paid out on termination is also generally taxed as ordinary income, though some components of long service leave may receive concessional treatment depending on when entitlements were accrued. The ATO’s guidance on leave payments has the full breakdown for termination scenarios.

One thing worth checking before you finalise any termination payout: ask your employer for a leave balance report from their payroll system and compare it against your own running tally. Payroll software sometimes applies the wrong ordinary hours figure — especially for employees who’ve had a contract change at some point — and a discrepancy of even one hour per week compounds quietly into a meaningful shortfall over several years of employment.
