Auto Leasing
A money factor is the way auto leases express interest cost. Multiply the money factor by 2,400 to get the equivalent APR. This calculator converts in both directions so you can compare lease deals with loan rates.
Instead of quoting an APR, auto leases use a money factor — a small decimal (e.g. 0.00125) that represents the monthly interest component. The money factor is applied to the sum of the capitalised cost and residual value to determine the monthly rent charge.
Dealers sometimes quote money factors because the small decimal looks less intimidating than the equivalent APR. Converting to APR lets you compare lease costs with traditional loan financing on equal terms.
Simple multiplication to convert.
APR = Money Factor × 2,400
Reverse: Money Factor = APR / 2,400. A money factor of 0.00125 = 3% APR.
The ×2,400 conversion is an approximation that works well for standard lease structures. It does not account for fees, taxes, or non-standard lease terms. Always review the full lease disclosure for the total cost.
Frequently asked questions
The money factor is essentially a monthly interest rate divided by 2 (because it’s applied to the average of capitalised cost + residual). Multiplying by 2 converts to a monthly rate, then by 12 to annualise: 2 × 12 × 100 = 2,400.
A money factor equivalent to the prevailing new-car loan APR is competitive. As of 2024–2026, money factors around 0.001–0.002 (2.4%–4.8% APR) are typical for well-qualified lessees on mainstream brands.
Yes. The money factor is based on the lessee’s credit score and the lessor’s buy rate. You can negotiate a lower money factor just like you would negotiate a loan rate. Ask the dealer to disclose the money factor before signing.
