Retro Pay Summary
What is Retroactive Pay?
Retroactive pay, often called “retro pay,” is the additional payment owed to an employee when their pay rate changes after they’ve already worked hours at the previous rate. This typically happens due to:
- Pay raises or promotions
- Wage adjustments due to negotiations or corrections
- Union agreements
- Minimum wage updates
For example, if your hourly rate was $20 but later increased to $25, retro pay ensures you are compensated for past hours worked at the higher rate.
How the Retro Pay Calculator Works
The calculator uses a simple formula to calculate retro pay:Retro Pay=(New Hourly Rate−Old Hourly Rate)×Hours Worked Retroactively
It subtracts your old rate from your new rate to find the difference and then multiplies that by the number of hours you worked during the retroactive period.
This ensures precise calculation without manual errors, saving time and avoiding payroll confusion.

Step 3: Enter Retroactive Hours Worked
