How to use the Pro-Rata / Furlough Salary Calculator
To use the pro-rata salary calculator, enter the full-time annual salary in the "Full-time Salary" box and the number of weekly hours that are considered "full-time" into the "Full-time weekly hours" box. If you are working out the new salary by number of hours worked, enter the pro-rata number of weekly hours into the "Pro-rata weekly hours" box. If you want to see a percentage of your current salary, enter that percentage into the "% of full-time salary" box.
Find out the benefit of that overtime! Enter the number of hours, and the rate at which you will get paid. For example, for 5 hours a month at time and a half, enter 5 @ 1.5. There are two options in case you have two different overtime rates. To keep the calculations simple, overtime rates are based on a normal week of 37.5 hours.
