Money factor is the interest rate on a lease. It is written as a small decimal, like 0.00150, which makes it hard to judge at a glance. That is the only reason it feels complicated.
Converting it to an interest rate
Multiply the money factor by 2,400:
- 0.00050 x 2400 = 1.2% APR
- 0.00150 x 2400 = 3.6% APR
- 0.00250 x 2400 = 6.0% APR
- 0.00400 x 2400 = 9.6% APR
The 2,400 is not arbitrary. It comes from the way the finance charge is built inside the lease payment formula, and it works for every lease.
Once you have the APR, you can compare a lease against a loan honestly, which is the whole point.
What counts as a good money factor
It depends on two things: your credit tier and whether the manufacturer is subsidising the lease.
Lenders publish a "buy rate" money factor for each credit tier. Strong credit gets the lowest one. As your tier drops, the money factor rises, and it can rise a lot. The difference between a top tier and a middling one is often worth more per month than a hard round of price negotiation.
Separately, manufacturers sometimes subsidise leases on specific models to move them. A subsidised money factor can be far below any normal rate, occasionally near zero. These are model and month specific, which is why the same credit profile can get very different rates on two cars in the same showroom.
The markup nobody mentions
A dealer is allowed to mark up the money factor above the lender's buy rate and keep the difference. This is legal and common, and it does not show up anywhere on a payment quote.
A markup of 0.00050 does not look like much. On the example lease in our payment breakdown, it adds about $29 a month, which is a little over $1,000 across a 36 month term.
So the useful question is not "what is the money factor?" It is "what is the buy rate, and is this marked up?"
How to check yours
You can work backwards from a quote. If you know the payment, the cap cost, the residual, and the term, the money factor is the only unknown left:
- Depreciation charge = (cap cost - residual) / term
- Finance charge = monthly payment - depreciation charge
- Money factor = finance charge / (cap cost + residual)
If the number that falls out is meaningfully higher than the published buy rate for your credit tier, you are looking at a markup.
What moves it in your favour
Your credit. This is the big one. Moving up a tier changes the rate you are offered on every car, not just one. If you are close to a tier boundary, a few points can be worth real money.
Shopping more than one lender. Different lenders assign tiers differently and subsidise different models. The same person can be a tier 1 with one bank and a tier 2 with another in the same week.
Asking directly. A quote that lists the money factor alongside the price and residual is a quote you can check. One that does not is a quote you have to take on faith.
That comparison across lenders is the part we handle. If you want to see what your profile actually qualifies for rather than what one dealership offers, send us the car you are after.
