Money Factor Calculator
Convert lease money factor to APR interest rate and vice versa. Calculate monthly financing costs and total interest for auto leases.
Convert Lease Money Factor to APR Interest Rate
The Money Factor Calculator translates auto lease money factors into annual percentage rate (APR) interest rates and vice versa. Car dealerships frequently express auto lease financing charges as a small decimal known as a money factor (for example, 0.0025). Converting this number to an equivalent APR allows car shoppers to compare lease interest rates directly with traditional auto loan rates.
Money Factor Conversion Formulas
The mathematical relationship between a lease money factor and an annual percentage rate is straightforward:
- Money Factor to APR: $\text{APR (\%)} = \text{Money Factor} \times 2400$
- APR to Money Factor: $\text{Money Factor} = \frac{\text{APR (\%)}}{2400}$
- Monthly Rent (Finance) Charge: $\text{Monthly Rent} = (\text{Capitalized Cost} + \text{Residual Value}) \times \text{Money Factor}$
How to Use the Calculator
- Select whether you want to convert Money Factor to APR or APR to Money Factor.
- Enter the lease money factor (e.g. 0.0025) or interest rate (e.g. 6.0%).
- Optionally enter vehicle capitalized cost, residual value, and lease term in months to estimate monthly finance fees and total lease costs.
- Review the equivalent APR interest rate, monthly rent charge, and estimated monthly lease payment in real time.
Frequently Asked Questions
Why do lease companies multiply money factor by 2400 to get APR?
The factor of 2400 combines converting a monthly rate to an annual rate (multiply by 12) and converting a decimal fraction to a percentage (multiply by 100), divided by 2 to average the beginning capitalized cost and ending residual value ($12 \times 100 \times 2 = 2400$).
What is considered a good money factor for a car lease?
A money factor equivalent to prevailing prime auto loan rates (e.g., 0.0015 to 0.0025, corresponding to 3.6% to 6.0% APR) is generally considered good for borrowers with excellent credit scores.
Is money factor negotiable when leasing a car?
Yes, while leasing companies set a buy rate base money factor, dealerships can mark up the money factor for additional profit. Negotiating the money factor down to the buy rate can significantly lower your monthly payment.
