Staffing Coverage Calculator

See how many employees you need to cover your shifts—and what overtime is costing you—accounting for the time your team spends away from the schedule.

Compare your staffing by positionEnter current staff for every position to see your total gap.

Coverage takes more than headcount. Employees also need to be onboarded, trained and qualified for the positions you fill. This is an annual estimate using average rotation hours; it doesn't simulate individual shifts.

What does your overtime cost?

Enter total paid overtime for each position across your whole team—not per employee. Include scheduled and extra overtime. Leave blank to use the staffing calculator on its own.

Calculation & assumptions

Coverage hours = units × hours per day × days per week × crew per unit.
Available hours = scheduled weekly hours × 52 − leave − training − other.
Employees needed per position = coverage hours ÷ available weekly hours, rounded up.
Overtime cost = hourly rate × OT hours per week × multiplier × 52.
Fire agencies using the FLSA 7(k) exemption may have a higher overtime threshold, so actual cost may differ.
