The Job That Looked Profitable Until You Did the Math

You quote a customer $2,500 for a job. They accept, your team works, and the customer pays. Yet after labor, materials, fuel, insurance, and administrative time, the profit is smaller than expected. A good-sized invoice is not the same as a profitable job.

Start with direct job costs

Include materials, labor, subcontractors, equipment rental, supplies, disposal, and job-specific travel. In a hypothetical job, materials cost $600, direct labor $700, equipment and supplies $150, and transportation $50. Direct costs total $1,500. A $2,500 invoice leaves $1,000 before overhead.

Account for expenses between jobs

Insurance, office expenses, software, administration, marketing, and other overhead must be supported by the work you sell. If monthly overhead is $6,000 and you complete 30 similar jobs, an average allocation is $200 per job. This is a planning method, not a universal accounting rule. In the example, estimated cost including allocated overhead is $1,700, leaving $800 before any additional costs.

Markup is not margin

Markup measures the amount added to cost; margin measures the portion of selling price remaining after the costs included. A job costing $1,700 and priced at $2,500 has approximately 47.1% markup and 32% margin. To price for a 30% margin on a defined cost base, divide cost by 0.70. $1,700 divided by 0.70 is approximately $2,429. This does not guarantee net profit.

Find your break-even point

The U.S. Small Business Administration defines break-even units as fixed costs divided by selling price per unit minus variable cost per unit. A service business might define a unit as a job, service hour, or package. Reference: https://www.sba.gov/counseling/plan-your-business/break-even-point-calculator/

Create a checklist before quoting

Account for labor, materials, subcontractors, overhead, time overruns, and scope changes. Put assumptions, exclusions, and change-order procedures in writing. Compare completed-job actuals with estimates: extra trips, longer labor, material increases, and customer changes reveal where future pricing needs adjustment.
