Method
How the calculation works
- Loaded OT cost = base wage × multiplier × (1 + burden) × paid hours
- Productive hours = paid hours × productivity factor
- Break-even rate = loaded OT cost ÷ productive hours
Worked example
Sixteen hours at a $30 wage, 1.5× premium, and 30% burden cost $936. At 90% productivity, the break-even customer rate is $65 per productive hour.
