How it works
Why your rate has to be so much higher than the wage
A tech’s wage is the smallest part of what an hour costs. Burden adds to every paid hour. Then only some of the paid hours can be billed, so the billed ones have to carry the rest. Then the whole business — the office, the trucks, the insurance, the software — is paid for out of those same billed hours. The break-even rate is where all of that is covered and nothing is left; the target rate adds the profit you want as a share of the rate.
How to calculate it by hand
Loaded cost per paid hour = pay × (1 + burden)
Billable hours per tech = paid hours × billable share
Labor per billable hour = loaded cost × paid hours ÷ billable hours
Overhead per billable hour = annual overhead ÷ (techs × billable hours)
Break-even rate = labor per billable hour + overhead per billable hour
Target rate = break-even ÷ (1 − target net profit)
With the example numbers: $30.00 pay and 30% burden is a loaded cost of $39.00 an hour. 2,080 paid hours at 65% billable is 1,352 billable hours per tech, so each billable hour carries $39.00 × 2,080 ÷ 1,352 = $60.00 of labor. Four techs bill 5,408 hours a year between them; $180,000 of overhead over 5,408 hours is $33.28 an hour. Break-even is $93.28. For 15% net profit, $93.28 ÷ 0.85 = $109.75 an hour.
Common mistakes
- Adding profit as a markup. $93.28 × 1.15 is $107.27, which leaves 13.0%, not 15%. A profit target is a share of the rate, so divide by (1 − target).
- Assuming every paid hour is billable. At 100% billable the same shop’s break-even looks like $60.63 — $32.65 an hour too low.
- Leaving the owner out of overhead. If the business could not run without your office time, that time has a cost.
- Using the lowest-paid tech’s wage. Use the average across the people who bill, weighted by their hours.
What good data looks like
Burden from payroll reports, not a guess. Overhead from last year’s profit and loss, with anything that belongs to a specific job (materials, subs, permits) taken out — those are priced on the job. Billable share from time actually clocked against jobs over a few months, because a busy week flatters it and a slow one does not.
How to improve it
- Recover billable time before raising the price: tighter routes, fewer supply-house runs, fewer callbacks. The calculator shows what five more points of billable time are worth to your break-even.
- Charge for the time that is currently free: trip charges, diagnostics, after-hours premiums.
- Price materials separately, at their own margin. This rate covers labor and overhead only.
