Formula
Money Factor → APR: APR (%) = Money Factor × 2400
APR → Money Factor: Money Factor = APR (%) ÷ 2400
The factor 2400 comes from multiplying the monthly interest conversion factor (×12) by the percentage conversion (×100) and then by 2 (because the money factor represents average balance financing).
How it works
A money factor is a decimal used by lessors to express the financing cost in a lease, analogous to an interest rate. Multiplying the money factor by 2400 converts it to an approximate annual percentage rate (APR), because a money factor implicitly represents half the monthly interest rate as a decimal (money factor = APR/24/100).
This relationship allows lessees to compare lease financing costs directly against conventional loan APRs when shopping for vehicles.
Worked example
Converting a dealer-quoted money factor
- Dealer quotes a money factor of 0.00125.
- Multiply by 2400: 0.00125 × 2400 = 3.00.
- The equivalent APR is 3.00%.
A money factor of 0.00125 equals an APR of 3.00%.
Common mistakes to avoid
- Multiplying the money factor by 1200 instead of 2400 — the correct conversion is MF x 2400 to get APR, because a money factor is a monthly interest factor and there are 12 months and a factor of 2 in the standard conversion.
- Comparing a money factor from one dealership to an APR from another lender without converting to the same basis — they are measuring the same cost but are not directly comparable until both are expressed as APR.
- Treating the money factor as the only cost in a lease; the residual value, acquisition fee, and cap cost reductions also significantly affect the total lease cost.
Key terms
- What is a money factor?
- A small decimal (e.g., 0.00125) used in auto leases to calculate the finance charge component of a monthly lease payment, set by the lender.
- Why multiply by 2400?
- The money factor approximates one-half of the monthly interest rate as a decimal. Multiplying by 2 gives the monthly rate, multiplying by 12 annualizes it, and multiplying by 100 converts it to a percentage: 2 × 12 × 100 = 2400.
- Is the money factor negotiable?
- The base money factor (buy rate) is set by the manufacturer's captive finance arm and is generally not negotiable, but dealers may mark it up. Always ask for the buy-rate money factor.
- What is a good money factor?
- A lower money factor means lower financing costs. For reference, a money factor of 0.00125 equals 3% APR; 0.00208 equals about 5% APR.
Frequently asked questions
- Why do dealers quote a money factor instead of an APR?
- Money factors are less intuitive and harder to compare directly with loan APRs, which makes it easier for dealers to obscure the financing cost. Converting to APR gives consumers a standardized rate they can compare with other financing options.
- What is a typical money factor for a new car lease?
- Money factors vary by lender, vehicle, credit tier, and market conditions. A money factor of 0.00100 to 0.00200 is common, equivalent to roughly 2.4% to 4.8% APR. Luxury makes often have lower money factors due to captive lender promotions.
- Can I negotiate the money factor?
- Possibly. Captive lenders (manufacturer-owned finance companies) set money factors, and dealers generally cannot go below those. However, dealers can mark up the money factor above the buy rate and keep the difference. Knowing the base buy rate lets you resist markups.
