Many septic contractors underprice jobs by forgetting to account for overhead, travel time, and equipment wear. A healthy installation business targets 25-40% gross margin to cover overhead and generate profit.
| System Type | Material Cost | Total Installed |
|---|---|---|
| Conventional Gravity | $3,000-$5,000 | $7,000-$15,000 |
| Pressure Distribution | $4,000-$7,000 | $10,000-$20,000 |

Not factoring in permit delays, soil surprises (rock, high water table), and warranty callbacks. Budget 5-10% contingency on every bid. Also ensure your overhead percentage covers insurance, truck payments, office costs, and your own salary.
