Costing calculator
Overtime Cost Calculator
Estimate the extra cost created by overtime and the labor cost per unit produced during those hours.
What this calculator does
- Calculate overtime premium, total labor cost, and unit cost impact for extra production hours.
- Use before approving overtime to recover schedule, add capacity, or cover demand spikes.
- Calculate overtime premium, total labor cost, and unit cost impact for extra production hours.
Formula used
- Overtime labor = rate × multiplier × hours × operators
- Premium cost = rate × (multiplier − 1) × hours × operators
- Overtime unit cost = overtime labor ÷ output
Inputs explained
- Regular loaded rate: undefined
- Overtime multiplier: undefined
- Overtime hours: undefined
- Operators: undefined
- Overtime output: undefined
How to use the result
- Use before approving overtime to recover schedule, add capacity, or cover demand spikes.
- This is a planning calculator. Validate assumptions against your process data before using the result as a final quote, schedule, or engineering decision.
Common questions
- Which inputs usually drive the overtime cost result? regular loaded rate, overtime multiplier, overtime hours, operators, and overtime output usually have the biggest effect. When one of those assumptions changes, rerun the calculator and compare the new $ / unit result before updating the plan.
- What does the overtime cost calculator do? Calculate overtime premium, total labor cost, and unit cost impact for extra production hours.
- What inputs do I need for the overtime cost calculator? You need regular loaded rate, overtime multiplier, overtime hours, operators, and overtime output. Use measured values from your line, quote package, supplier data, or current production plan whenever possible.
- How should I interpret the overtime cost result? Treat the $ / unit output as a planning estimate for costing work. Compare it against process history, quoted assumptions, and operating limits before making final decisions.
