How the calculation works
What makes up your on-call costs
Your on-call costs include technician response pay, flat weekly pay, and the office time needed to coordinate calls. The calculator shows the total for one week, a full year, and each response hour.
The starting flat-pay figure of $50 per week is a planning assumption. Enter the amount used in your rotation. Federal rules may count on-call time as hours worked depending on the restrictions placed on the employee.

Weekly on-call cost
Weekly cost combines flat on-call pay, technician response pay, and dispatch or office time. At the starting figures, two calls of two hours each at $29 per hour, plus 30 minutes of office time per call at $30 per hour, and $50 flat pay, produce a weekly estimate of $196.
Cost per response hour, including all costs
Cost per response hour equals weekly cost divided by response hours. At the starting figures, $196 over 4 response hours equals $49 per response hour, including flat pay and office time. Compare this amount with revenue from after-hours service calls.
How flat pay affects the total
In the starting example, $50 in flat weekly pay makes up approximately one quarter of the $196 total. Technician response pay and office time make up the rest.
