Billable hours in an 8 hour day compared
The productive hours field is the one everybody skips, and it moves the true cost more than any tax rate does.
| Billable hours in an 8 hour day | True cost per billable hour | Burden over base wage |
|---|---|---|
| 6 of 8 | $31.86 | 77% |
| 6.5 of 8 | $29.41 | 63.4% |

What else matters here
Eighteen dollars an hour is a helper or a first year apprentice, and the payroll line is the smallest part of what they cost. Add FICA, comp, unemployment, liability and benefits and every paid hour is $23.90. Divide that across the hours you can actually invoice and a billable hour costs $29.41.
That is 63.4 percent over the wage, the highest burden percentage on this page. Burden is heaviest on the lowest wage, because the fixed dollar items, benefits in particular, are the same money spread over a smaller base.
If you are estimating a helper at $18 and adding a round 30 percent, you are short by more than half the burden. On a 200 hour job that gap is about $2,300 that never had a line on the estimate.
What this calculator assumes
- FICA is fixed at 7.65 percent, the employer half of Social Security and Medicare.
- Workers comp rates are set per trade and per state and swing enormously. Roofing can run over 25 percent where office work is under 1. Use your own rate off your policy.
- The productive hours field is the one everybody skips and it is the one that decides whether the job makes money. Drive time, loading, fuel stops and cleanup are paid and unbilled.
Questions people ask
What does an $18 an hour employee really cost?
$23.90 per paid hour with burden, and $29.41 per billable hour at 6.5 productive hours in an 8 hour day.
What counts as a productive hour?
Only the hours you can put on an invoice. Drive time, loading the truck, fuel stops, dump runs and cleanup are all paid and none of them are billable. Six and a half out of eight is a realistic default and plenty of crews are below it.
Why is workers comp set at 9 percent here?
Because it is a middle of the road number and the calculator has to open with something. Comp rates are set per trade and per state and they swing enormously, from under 1 percent for office work to over 25 percent for roofing. Put your own rate off your policy into the field.
