Multiply technicians by elapsed job hours and loaded rate. Add materials, equipment, travel, permits, overhead, and the reserve. Apply the margin to that total. Overrun scenarios keep the customer quote fixed and charge additional labor against it.
Worked example
Two technicians working three hours at $40 each cost $240. With $210 of other costs and a $50 reserve, planned cost is $500. A 20% margin gives a $625 quote and $125 of profit if the reserve is spent.
How this calculator works
- Choose the scope and enter your unit costs, crew or schedule assumptions.
- Read the estimated costs and the result based on the inputs above.
- Compare scenarios before copying or printing your estimate.
Use separate scope for diagnostics, fixture replacement, and rough-in. Identify which work includes inspection or special access, and document exclusions before providing a fixed quote.

Frequently asked questions
Does an unused reserve increase profit?
Yes. If none of the reserve is spent, profit rises by the reserve amount. The shown overrun scenarios are additional to the budgeted reserve.
What is the minimum profitable price?
It is the first whole cent above planned cost. It leaves almost no room for errors or extra work.
