Common questions

How much does floor plan financing cost on a used car?
Roughly origination + (vehicle cost × annual rate × days held ÷ 365) + monthly fees. On a $15,000 car at 8% APR held 60 days with $75 origination + $20/month, that works out to about $312, or 2.1% of the vehicle. Every extra 30 days adds another ~$100 of interest on a typical unit.
What APR do floor plan providers actually charge?
Typical 2026 ranges: NextGear Capital 6.99–9.99%, AFC 6.5–10%, Westlake Floor Plan 7.99–12.99%, Manheim Floorplan 6.5–9%, OPENLANE 6.99–9.5%. Most providers layer curtailment payments on top (10% of principal at day 30, 10% at 60, payoff at 90–120).
Should I floor plan all my inventory or pay cash?
Cash maximizes per-unit profit but caps inventory at your bank balance. Floor planning scales you to 3–5× more units but skims $200–600 off each deal. Floor plan wins when you (a) turn under 60 days, (b) average gross above $2,500, and (c) inventory scale grows front-end gross faster than floor cost grows. Run the math per unit — that's what this calculator is for.
What are curtailment payments?
Curtailment = a required pay-down of principal at set intervals (typical: 10% at day 30, 10% at 60), with a full payoff demanded at day 90 or 120 if the unit hasn't sold. Miss a curtailment and the rate jumps or the unit gets demanded. This calculator shows interest on full principal, which slightly overstates total cost if you make every curtailment on time.
