Practical pricing note for owner-operated service businesses. A percentage added to costs is markup. The percentage of the selling price left after those costs is margin. Confusing the two can cause a quote to miss its intended margin even when the arithmetic looks correct.
The $700 cost example
Assume a job has $700 in modeled direct and allocated costs. Those costs should include applicable loaded labor, materials, travel, overhead allocation and other expected job expenses. These figures are illustrative, not an industry rate card.
| Pricing question | Calculation | Result |
|---|---|---|
| Cost plus 30% markup | $700 ร 1.30 | $910.00 |
| Modeled surplus after included job costs | $910 โ $700 | $210.00 |
| Modeled margin at $910 | $210 รท $910 | 23.08% |
| Price for a 30% target margin | $700 รท (1 โ 0.30) | $1,000.00 |
The difference is $90 of selling price. Neither a 30% markup nor a 30% modeled margin establishes that a particular customer will accept the quote, or that your cost estimate is complete.
A different case: when $700 is the quoted selling price
If the selling price is $700 and it was calculated using a 30% markup, the implied cost is approximately $538.46. At that same cost, the selling price for a 30% margin would be approximately $769.23. Always state whether the starting number is cost or selling price.
Five checks before sending a quote
- Record the full work scope, exclusions, change-order assumptions and labor hours.
- Use your business’s loaded labor cost rather than an employee’s base wage alone.
- Include travel, materials, overhead allocation and a reasonable allowance for expected rework.
- Calculate both markup and margin. Identify any card-processing or selling fees that reduce the realized result.
- Review the customer’s ability to pay and competitive alternatives separately; the calculator does not validate market demand.
