The Precision Guide™ to Calculating Profit Margin
Revenue is not profit. Understanding profit margin helps you determine whether your pricing is creating a sustainable business or simply generating busy work.
Revenue Isn't Profit
Large sales numbers can still produce poor financial results if costs are not controlled.
Measure Every Job
Compare estimated versus actual profit to improve future pricing.
Protect Your Margin
Track labor, materials, overhead, and callbacks before celebrating revenue.
Why Profit Margin Matters
Profit margin measures how much of every sales dollar remains after covering business expenses. Healthy margins allow a company to replace equipment, survive slow seasons, invest in marketing, hire employees, and grow with confidence.
The Precision Framework™
Know Revenue
Track what the customer actually pays.
Subtract Direct Costs
Labor, materials, subcontractors, and job-specific expenses.
Recover Overhead

Calculate Margin
Measure the percentage of revenue that remains as profit.
Gross Profit vs. Net Profit
Gross Profit
Revenue minus direct job costs. Useful for evaluating the work itself.
Net Profit
What remains after overhead, operating expenses, taxes, and other business costs.
Common Profit Killers
Underpricing
Charging less than your true costs require.
Ignoring Callbacks
Warranty work and mistakes reduce margin.
Tracking Revenue Only
Revenue without cost analysis hides problems.
No Job Reviews
Failing to compare estimated versus actual performance.
