Owner-operator guide
Owner-Operator Profit Calculator
Gross revenue isn't profit. To know what your trucking business really earns, subtract every operating cost — then look separately at loan principal, taxes and what you pay yourself.
How owner-operator profit is calculated
Operating profit = gross revenue − operating expenses. Operating expenses include fuel, insurance, maintenance, repairs, tires, permits, registration, tolls, parking, ELD, accounting, factoring and dispatch fees, plus the interest part of equipment payments.
Divide operating profit by revenue for your operating margin, and by total miles (loaded + empty) for profit per mile.
Operating profit vs. cash flow
The principal part of a truck loan isn't an operating expense — it pays down debt and builds equity. But it still leaves your bank account. That's why a good analysis shows two numbers: operating profit (excluding principal) and cash flow (after principal).
Neither is your personal take-home pay. Income and self-employment taxes, owner draws and personal expenses come after.
Mixing weekly, monthly and annual costs
Insurance is often monthly, permits yearly and fuel weekly. Convert everything to an annual figure first: monthly × 12, weekly fixed costs × 52, and weekly running costs × the weeks you actually work. Then divide back to per-week or per-month.
Worked example (illustrative numbers)
| Revenue: $7,000/wk × 50 wks | $350,000 |
| Fuel: 3,000 mi ÷ 6.5 MPG × $3.80 × 50 | $87,692 |
| Other operating costs | $80,000 |
| Operating profit | $182,308 |
| Operating margin | 52.1% |
| Profit per mile (150,000 mi) | $1.215 |
Example only — your costs will differ. Run your own numbers in the calculator.
FAQ
Is truck payment principal a business expense?
For profit purposes, principal is debt repayment, not an operating expense; depreciation is how equipment cost is usually recognized for taxes. Ask a tax professional how this applies to you. Cash flow still needs to cover principal.
Should I include empty miles?
Yes. Per-mile profit and cost should use total miles driven, because fuel and wear happen on empty miles too. Revenue per loaded mile is useful as a separate number.
