Estimate service gross margin from billed revenue and the direct cost to deliver the work.
Use this service margin calculator to check whether a quote leaves enough room after the direct delivery cost is removed. The calculator is designed to give a fast answer, but the quality of the answer still depends on accurate inputs and a clear idea of what decision you are trying to support.
- Enter Revenue and Cost using the same units you plan to compare or report.
- Read the main gross profit margin first, then use the supporting outputs to understand the trade-offs behind that result.
- Compare your numbers with the worked examples below if you want a quick reasonableness check.
Margin and markup answer different business questions, so the calculator shows both. That helps when pricing products, reviewing offers, or understanding how efficiently revenue turns into profit. On this page, the primary output is gross profit margin.
Scenario 1: $2,800 billed revenue with $1,450 direct delivery cost. Inputs used: revenue: 2800, cost: 1450. Example result: 48.21%. This service package produces a gross margin of 48.21%. Scenario 2: $6,400 billed revenue with $3,100 delivery cost. Inputs used: revenue: 6400, cost: 3100. Example result: 51.56%. At this service price point, the gross margin works out to 51.56%.
Core formula: gross margin = (revenue - cost) / revenue * 100. The calculator measures profit in dollars first, then shows both gross margin on revenue and markup on cost.
- Margin answers how much of revenue becomes profit.
- Markup answers how much profit you earn relative to cost.
Use this calculator when pricing products, reviewing campaign profitability, or checking whether costs are crowding out profit. Related paths for follow-up analysis include profit margin calculator, gross margin calculator, markup calculator, and gross profit calculator.
Most bad outputs come from a few repeated input errors or interpretation mistakes. Use this short checklist before relying on the result.
- Confusing margin with markup.
- Leaving out costs that materially affect unit economics.
- Looking only at revenue growth without monitoring gross profit quality.
