What Is Leave Loading and How to Calculate It the Right Way?

If your organization manages a globally distributed workforce, you have likely encountered the term "leave loading" in award documents or enterprise agreements. For HR professionals based in the United States, understanding this entitlement is critical for cross border payroll compliance.

This guide breaks down what it is, how it works, who qualifies, and how to calculate it correctly.

1.0 What is leave loading?

Leave loading is an extra payment made to employees who take annual leave. It compensates for the loss of penalty rates or overtime pay that the employee would have earned whilst working. The standard rate at which this benefit is offered to Australian employees is 17.5% of the employee's base pay.

This entitlement applies only to annual leave, not to sick leave or personal leave. Furthermore, not all employees qualify. Only those covered by a relevant award or contract will receive the additional payment.

Element	Detail
Standard rate	17.5% of base pay
Applicable leave type	Paid annual leave only
Who determines entitlement	Employee's award, enterprise agreement, or contract
Legal mandate	Not part of the National Employment Standards
Common recipients	Full time and part time employees covered by most modern awards
Origin	Australian labour movement in the 1970s to offset lost overtime and penalty rates

1.1 How does leave loading work?

This benefit evens out the difference between the employee's pay while working and whilst on leave. During leave, the employee receives their regular pay plus the additional loading percentage. For most modern awards, the percentage is 17.5%. In a few awards, however, a comparison is required between the base pay plus 17.5% and what the employee would have earned in penalty rates.

Hence, the entitlement may be higher for those who work odd shifts with penalty rates. The additional payment is made at the same time as the employee's annual leave pay. Some organisations choose to pay it separately, while others include it in each pay cycle.

Unlike Australia, this type of entitlement does not exist in the USA. The Fair Labor Standards Act does not provide for paid vacation leave, let alone an extra loading on that leave. The provision of vacation leave is left to the discretion of the employer and employee.

Managing this entitlement for Australian employees from a U.S.-based HR system can introduce data-sync errors and compliance gaps. Salary.com's HRIS / HCM integrations connect directly with ADP, Workday, UKG, Dayforce, and Paylocity, keeping employee records, award classifications, and pay entitlements synchronized across borders so it is never missed or miscalculated.

2.0 How to calculate leave loading

To calculate the entitlement for a full time employee who takes four weeks of leave:

Annual leave loading = 4 x 17.5% x Employee's weekly rate of pay

For part time employees, the calculation works the same way, but uses the employee's ordinary hours to determine the percentage of pay they will receive on leave.

Steps to calculate:

1. Determine the employee's ordinary time earnings, which is their weekly rate of pay

2. Find the loading rate (17.5%)

3. Multiply the employee's weekly pay by the loading percentage

4. Multiply the result by the number of weeks of leave the employee will take (four for full time)

Example: A full time employee who earns $1,200 per week will receive $1,200 x 17.5% = $210 in loading for each week of leave. Hence, the employee will receive $210 x 4 = $840 in total for their four weeks of leave.

Manually computing this entitlement across dozens or hundreds of roles invites errors — especially when different awards carry different rates. CompAnalyst is an all-in-one benchmarking platform that lets you price jobs, build salary structures, and model pay scenarios including the calculations.

2.1 How is the standard 17.5% annual leave loading calculated?

The percentage of 17.5% was established in the 1970s when most employees earned their income from overtime and penalty rates. Hence, if they took leave then they lost that income. The 17.5% was a rounded up average of that income that they lost during that time. This percentage has been carried forward into most awards since then.

In a few awards, the applicable rate is the higher percentage between the 17.5% and the rate that the employee would have earned in penalty rates during that period. This is commonly used in retail and hospitality industries for employees whose shifts may not coincide with standard working hours. For these industries, the employee's award must be consulted.

3.0 How is leave loading paid out when an employee leaves?

When an employee leaves a position with an organization, the employee is entitled to any annual leave that they have accrued but not taken. Furthermore, if the award under which they are employed includes loading, they are entitled to the loading on the leave that they have not yet taken.

Component	Calculation
Unused annual leave	Hours accrued but not taken x base rate of pay
Loading on unused leave	Unused annual leave amount x 17.5% (or applicable rate)
Total payout	Unused annual leave + loading
Payment timing	Included in employee's final pay

3.1 What are the most common termination payout mistakes with leave loading?

Mistakes in the calculation and payment of loading upon an employee's termination from their job are of high concern in recent years. From January 2025, the underpayment of wages of an employee with intent to the criminal law of Australia.

The penalty for these actions is fines of up to $7.8 million for the company, or imprisonment of up to ten years for the individual involved.

The most common mistakes that are made are:

• Omitting the loading from final pay: Employers pay out unused annual leave but forget this component.

• Assuming all employees qualify: Casual employees are generally not entitled since they do not accrue annual leave. Always verify the employee's award.

• Ignoring the comparison method: Some awards require paying the higher of 17.5% or actual penalty rates. A flat rate can underpay shift workers.

• Mishandling annualised salarie: The September 2025 Federal Court decision in Fair Work Ombudsman v Woolworths Group Limited ([2025] FCA 1092) confirmed that annualised salary arrangements cannot offset award entitlements across pay periods. Every entitlement, including the loading component, must be accounted for each pay period.

The termination payout errors listed above are exactly the kind of mistakes that manual processes produce. CompXL automates the calculation and distribution of raises, bonuses, and award-based entitlements, including these entitlements.

4.0 FAQs

Here are the frequent questions about the topic:

4.1 Do part time employees get leave loading?

Yes. Part time employees receive the loading at the same rate as full time employees. However, their total amount will be less due to the number of hours that they work and accrue as leave.

4.2 What is the difference between leave loading and casual loading?

Leave loading occurs when a permanent employee accrues leave and receives an additional loading on their pay for those days off. Casual loading is a rate of pay of 25% per hour for casual employees who do not accrue paid leave or redundancy pay. Hence, casual employees do not the annual leave entitlement.

4.3 Is leave loading taxed differently from normal pay?

It is taxed in the same way as the employee's other income. It is taxed at the same rate as their wages with PAYG tax deductions. However, any lump sum payment of unused leave and loading that is paid out upon an employee's termination may be taxed at a different rate. For details on how to calculate leave and loading tax for employees upon their termination, refer to the guidelines from the Australian Taxation Office.

4.4 Can an employer include leave loading in an annualised salary?

Yes, but with some conditions. The salary arrangement must explicitly state the various entitlements covered. Furthermore, the total payment of the employee must not leave them financially worse off when compared to their entitlement under the award. Such an agreement must be met every pay period.
