How the Rate per Hour Calculator Works
The Rate per Hour Calculator divides a timed count by the elapsed time and scales the result to 1 hour. You count for any length of time, and the tool converts the result into an hourly rate.
- Start the timer: The first tap or the Start button begins timing.
- Count events: Tap once per event, such as each car or customer.
- Stop the timer: Press Stop at the end of the count period.
- Read the hourly rate: The tool shows the count, the elapsed time and the rate per hour.
Rate per Hour Calculator Formula
The Rate per Hour Calculator result equals the count divided by the elapsed minutes, multiplied by 60.
