Before you buy the car,
know the numbers.
Estimate how purchase price, rental demand, expenses and financing affect the profitability of a vehicle in your fleet. No account, download or spreadsheet required.
Updates as you change your assumptions
Scenario estimates. The same fixed expenses, loan terms and price assumptions apply.
What the numbers mean
Cash flow
Monthly revenue after cash operating costs and, when financed, your scheduled loan payment. It does not include income tax.
Economic return
Asset ROI estimates operating profit after depreciation, while cash-on-cash ROI compares cash flow with the cash initially invested.
Break-even
The minimum rental rate or utilization required to cover modeled operating cash costs and debt service at your other inputs.
Go beyond a quick estimate.
Our paid Investment Analyzer PRO workbook adds three-year projections, amortization schedules, scenario analysis, ownership equity and alternative-investment comparisons.
- Three-year vehicle ownership forecast

Are these figures a forecast of actual earnings?+
No. They are scenario estimates based on manual assumptions. Real demand, repairs, taxes and vehicle resale values can vary significantly.
Does the calculator save my financial numbers?+
No. Calculations run locally in your browser. Inputs are not uploaded or stored on our servers. Optional Google Analytics tracks site activity only after consent, not your financial field values.
How does the free calculator differ from the paid spreadsheet?+
The free tool offers a quick single-vehicle estimate. The Excel workbook includes additional scenarios, financing tables and three-year analysis.
Why can economic profit differ from cash flow?+
Cash flow includes scheduled loan principal payments, while simplified economic profit subtracts depreciation and estimated loan interest instead. They measure different things.
