Overtime is legitimate spend right up until it becomes a habit that covers for a broken schedule, an unfilled seat, or a supervision gap. This calculator prices the habit and estimates how much of it is avoidable.
This tool estimates operational overtime cost. It assumes overtime is being correctly paid; if hours are worked but not paid, that is compliance exposure, and the Unpaid Overtime Exposure Estimator is the right tool.
Under the FLSA, covered nonexempt employees earn at least 1.5 times their regular rate for hours over 40 in a workweek. Total overtime cost is hours times rate times 1.5. The premium portion, hours times rate times 0.5, is the pure surcharge you pay for buying labor in overtime instead of straight time. That premium is what better staffing directly recovers.
Overtime caused by seasonal demand is mostly unavoidable, around 10%. Overtime caused by scheduling inefficiency runs about 25% avoidable, vacancy coverage 40%, chronic understaffing 50%, and broken workflow or supervision 60%, because those causes are fully within the employer's control.
Annual avoidable overtime versus the loaded cost of the staffing or scheduling fix. When chronic overtime exceeds roughly 60% of a position's cost, adding the position is usually cheaper, and it removes the burnout and error risk that overtime carries with it.
No. Flexible, occasional overtime is often the cheapest way to handle demand spikes. The leak is chronic overtime, the kind that appears in the same departments every single week, because that means overtime has become the staffing plan.
Look at where it concentrates. Overtime spread thin across the organization is demand. Overtime concentrated in one department, shift, or supervisor is structure: a vacancy, a scheduling problem, or unmanaged workflow.
Some do, and modest voluntary overtime can help retention. It becomes a problem when the organization depends on it: the moment those employees say no, take leave, or quit, the operation has no plan B.
This calculator uses your average base rate for simplicity. Legally, nondiscretionary bonuses and commissions must be included in the regular rate used for overtime, which is a common and expensive payroll error. If that might be happening, run the Unpaid Overtime Exposure Estimator.
