Overhead rate compared
Profit is held at 10 percent and only the overhead rate moves, so the last column shows what the wrong method would have charged at each level.
| Overhead rate | Price the job at | Markup this equals | If you had added the percent to cost instead |
|---|---|---|---|
| 10% | $125,000.00 | 25% | $120,000.00 |
| 15% | $133,333.33 | 33.3% | $125,000.00 |
| 20% | $142,857.14 | 42.9% | $130,000.00 |

What else matters here
A $100,000 cost prices at $133,333.33, with $20,000 of overhead recovered and $13,333.33 of profit.
On a job this size the cost estimate matters more than the percentage. Fifteen percent of overhead on $100,000 is $20,000 of recovery; a 10 percent error in the labor estimate can be half of that on its own. Get the cost right first, then apply the percentages to it.
The $8,333 gap between this price and the naive $125,000 is the reason to price with margins rather than markups. It is not a philosophical point, it is a truck, a year of insurance, and the deposit on the next one.
What this calculator assumes
- The classic 10 and 10 is overhead 10 percent and profit 10 percent. Almost nobody's overhead is actually 10 percent, so work out your own: last year's overhead divided by last year's revenue.
- Both numbers here are treated as margins, taken out of the price, not markups added to cost. That is the conservative reading and it is the one that leaves you whole.
- The wrong way, adding 25 percent to cost and calling it 25 percent O and P, leaves you 5 percentage points short on a $24,000 job. The comparison is below.
Questions people ask
What should I charge for a job that costs me $100,000?
$133,333.33 with 15 percent overhead and 10 percent profit, a 33.3 percent markup on cost.
Why not just add the percentage to the cost?
Because a percentage added to cost comes back out of the price as a smaller percentage. Adding 25 percent to a $50,000 cost gives $62,500, and 25 percent of that price is $15,625, not the $12,500 you added. The calculator treats both figures as margins taken out of the price, which is the reading that leaves you whole.
How do I work out my real overhead percentage?
Last year's overhead divided by last year's revenue. Overhead is everything that is not job cost: insurance, the truck, the phone, software, the accountant, advertising, your office time. Almost nobody's overhead is the 10 percent in the old rule of thumb.
