Time and a half is one of those phrases everyone has heard and fewer people can calculate on the spot. It is a simple idea with a simple formula, and knowing it well enough to do in your head is genuinely useful when you are deciding whether to pick up an extra shift.
The definition
Time and a half means you are paid 1.5 times your ordinary hourly rate for the hours in question. Your normal hour plus half an hour again. That is the whole concept.
The formula
Multiply your ordinary hourly rate by 1.5, then multiply by the number of hours worked at that rate. Written out: hourly rate × 1.5 × hours = total for those hours.
Worked examples
Say your ordinary rate is $30 an hour. Time and a half is $30 × 1.5 = $45 an hour. Work four hours at that rate and you have earned $180 for those four hours, rather than the $120 they would have been at your ordinary rate.
A second example with a less round number. On $27.50 an hour, time and a half is $27.50 × 1.5 = $41.25. Six hours at that rate comes to $247.50.
A quick mental shortcut: take your hourly rate, halve it, and add it back. On $34 an hour, half is $17, so time and a half is $51. That is faster than multiplying by 1.5 under pressure.
If you would rather not do it by hand, our time and a half calculator takes your hourly rate and hours and returns the total.
When time and a half usually applies
- The first few hours of overtime in a day or week, under many awards.
- Saturday work, under a number of awards.
- Some evening or early-morning shifts falling outside the span of ordinary hours.
- Certain public holiday arrangements, though double time is more common for holidays.
The consistent theme is that time and a half is typically the first step up, with double time reserved for longer overtime, Sundays or public holidays. But this is a pattern, not a rule — your award decides.
What time and a half is calculated on
This trips people up. The multiplier normally applies to your ordinary base rate, not to your total take-home including allowances. Tool allowances, travel allowances and similar payments are generally treated separately rather than being multiplied.
For casual employees, whether the 1.5 applies before or after the casual loading depends on the award. That distinction can be worth several dollars an hour, so it is worth checking rather than assuming — our guide on casual loading versus overtime covers it.
Checking it on your payslip
A compliant payslip should let you see the rate and the hours separately, rather than only a lump sum. If you can see “4 hours @ $45.00” you can verify it in seconds. If you can only see a total, you cannot check anything, and you are entitled to ask for the breakdown. Our guide on reading your payslip covers what should be there.
