Understanding Your Payslip: Overtime, Penalties and Allowances
By My Overtime · Published 18 October 2026
Your bank deposit tells you how much money arrived. Your payslip helps explain how that payment was worked out.
When your hours or duties change, checking the individual payment components can be more useful than looking at the final total alone. Here is a practical guide to reading them.
Start with the pay period
Before comparing two payslips, check the dates each one covers.
A weekly payment and a fortnightly payment are different-sized periods. Also look for back payments, leave or adjustments that could make one period unusual.
Use amounts for the current pay period, rather than accidentally comparing year-to-date totals.
Ordinary pay: your starting point
Look for the line showing ordinary hours and the rate paid for those hours.
Payroll labels vary. If a description is unclear, ask payroll what it includes before using it in a comparison.
Your gross pay is the amount before deductions. Net pay is what remains after deductions. Keep these separate and use gross figures consistently for My Overtime’s gross-earnings questions.
Overtime: check the hours and the rate
Overtime generally concerns work outside ordinary hours as defined by the applicable employment arrangements. When overtime applies and how it is paid depend on the relevant award, enterprise agreement or other applicable terms.
Do not assume every hour above 38 attracts the same overtime rate for every worker.
On your payslip, check:
- How many overtime hours are recorded.
- The rate or multiplier shown.
- Whether separate overtime categories appear.
- Whether the amount is the full payment or an additional loading.
Some payroll systems split payments across several lines. Ask for an explanation if adding them together could count the same payment twice.
Penalty rates: check when the work happened
Penalty rates may apply to particular working times, such as weekends, public holidays or certain shifts. The applicable rules and rates depend on the employment arrangements covering the work.
Overtime and penalty payments are not necessarily added together. Check the relevant rules rather than assuming both apply cumulatively.
Compare your payslip with your roster or timesheet. This helps you ask specific questions about the hours recorded.
Allowances: understand what each one represents
Allowances can relate to particular duties, working conditions, skills or expenses. Different allowances serve different purposes.
For each allowance, ask:
- What is it paid for?
- Is it calculated per hour, shift, day or another unit?
- Does it depend on performing a particular duty?
- Is it an expense-related payment or another kind of allowance?
Do not assume every allowance is treated identically when calculating workers compensation or other entitlements.
A fictional example of an earnings change
Imagine these amounts appear in two weekly pay periods:
| Payment component | Before the change | During light duties |
|---|---|---|
| Ordinary pay | $1,000 | $1,000 |
| Overtime | $300 | $0 |
| Penalty payments | $100 | $0 |
| Allowances | $50 | $20 |
| Total shown in this example | $1,450 | $1,020 |
The arithmetic difference is $430 for that week.
These are fictional amounts, not prescribed pay rates. The example assumes the components are separate and have not already been included in another line.
A $430 difference does not establish that $430 is legally owed. Whether any payment should continue, or compensation is payable, requires the applicable rules and individual circumstances to be considered.
When something does not look right
Keep the payslip and the matching roster or timesheet. Highlight the line you want explained.
You could ask payroll:
“Could you please explain the hours, rates and allowance conditions used for this pay period, including any changes from the previous period?”
A clear question is more useful than assuming a lower payment proves an error.
If the explanation does not resolve your concern, consider assistance from your union, the relevant regulator or a qualified adviser.
Using My Overtime
The My Overtime calculator helps organise a comparison of gross weekly earnings. Its separate NSW illustration is restricted to supported scenarios and has additional conditions and exclusions.
Neither an earnings comparison nor a payslip total automatically establishes compensation owed.
