This article explains how Deputy calculates the multipliers for our Australian awards.
We often have customers misunderstand by why a multiplier looks different than they expected (e.g. why a casual Saturday rate isn't just "1.5x).
We use the rates from the pay guide of the award on the Fairwork website:
https://www.fairwork.gov.au/pay-and-wages/minimum-wages/pay-guides
Example
This is the Fast Food Industry Award pay guide:
To calculate the multipliers, Deputy takes the value of each rate and divides it by the hourly pay rate. Let's look at some calculation examples:
FT/PT Level 1 Saturday Rate $30.91 / Hourly Rate $24.73 = 1.25x
CAS Level 1 Saturday Rate $30.91 / Hourly Rate $37.10 / $30.91 = 1.20x
You can also check the rates yourself with a step by step:
Find the Penalty Rate on your Fair Work pay guide.
Find the Base Hourly Rate for that employee.
Divide Penalty by Base.
The result is the multiplier you should see in Deputy.
A full list of multipliers for this award are listed in our Fast Food Industry Award (FFIA) help article.
The rates below are from the Fairwork document:

The above table shows the % rate based on a minimum hourly rate. The minimum hourly rate is always calculated based on the FT/PT minimum hourly rate.
The casual % rate states for Saturday it is 150% off the minimum hourly rate which is the "FT/PT" hourly rate of $24.73.
The calculation works out to be $24.73 x 150% = $37.10 which is the Saturday rate for a casual employee.
