Water Job Margin Calculator
Enter the job total and the costs you expect to assign to it. The calculator separates direct cost, overhead allocation, and modeled net profit so you can review the assumptions with your bookkeeper.
How the calculation works
Direct costs are the labor, materials, equipment, subcontractor, disposal, and permit entries. Gross profit is revenue minus those direct costs. The overhead allocation is the percentage you entered multiplied by revenue. Modeled net profit subtracts both direct cost and overhead allocation from revenue.
The output is only as useful as the inputs. Compare estimated costs with closed-job actuals and update the assumptions instead of treating a target percentage as a universal industry benchmark.
Keep the margin after the quote.
