What Is a Money Factor on a Car Lease? How to Convert It to APR (and Negotiate It)

Short answer: A money factor is a small decimal, such as 0.00250, that many leasing companies use to calculate the rent charge in your lease payment. The rent charge is the lease version of interest. To compare it with a loan rate, multiply the money factor by 2,400 (0.00250 x 2,400 = about 6% APR). It's often at least partly negotiable, but the bigger lever is usually the vehicle's price. Ask for the money factor in writing, convert it, and compare full lease quotes, not just monthly payments.

What a money factor is

A lease payment has two main parts: depreciation (the car's expected loss in value over the lease) and the rent charge, which the Federal Reserve's consumer leasing guide describes as similar to interest on a loan. According to that guide, the rent charge is usually determined using a money factor, sometimes called a lease factor.

The Federal Reserve also notes the money factor "is not a lease rate and cannot be converted to a lease rate by moving the decimal point" (0.00250 doesn't mean 0.25%), and that it "typically is not disclosed to you." Your lease shows the rent charge in dollars, so if you want the factor, ask.

The lease terms that set your payment

Federal Regulation M, which implements the Consumer Leasing Act, requires a motor vehicle lease to show how the payment is calculated. These are the lines you'll see:

Regulation M also gives you the right to a separate written itemization of the gross capitalized cost, provided before you sign if you ask for it.

How the money factor sets the rent charge

The Federal Reserve gives the formula: the average monthly rent charge equals the money factor times the sum of the adjusted capitalized cost and the residual value.

Monthly rent charge = money factor x (adjusted capitalized cost + residual value)

Its example: money factor 0.00354, adjusted capitalized cost $18,800, residual value $12,350: 0.00354 x $31,150 = $110.27 a month.

So the rent charge grows with the money factor and with the capitalized cost. A higher price or add-ons rolled into the lease raise both rent charge and depreciation.

How to convert a money factor to APR

The common rule of thumb is simple:

• Money factor x 2,400 = approximate APR (%)
• APR (%) / 2,400 = approximate money factor

Consumer Reports gives the same conversion: 0.00166 x 2,400 is about a 4% rate, and an 8% rate is a money factor of about 0.00333.

Conversion table (math only, not typical or current rates):

Why 2,400? The formula applies the factor to the starting plus ending balance, about twice the average balance. A loan charges APR / 12 a month on its balance, so the equivalent factor is APR / 24, and expressing the rate as a percent (x 100) gives 2,400.

Treat the result as a yardstick, not a contract rate. The Federal Reserve notes there's no federal requirement to disclose a lease rate and no mandatory formula for one. Under Regulation M, a lessor that shows a percentage rate must add a notice that "this percentage may not measure the overall cost of financing this lease," and may not call it an "annual percentage rate." Use the converted number to compare quotes, or to compare against a loan rate.

Is the money factor negotiable?

Often, at least partly. The CFPB lists the "rental charge or money factor" among lease terms consumers commonly negotiate, along with the vehicle's cost, residual value, down payment, trade-in, mileage limit, and purchase option. Consumer Reports agrees.

The Federal Reserve adds a caveat: the rent charge is often set by the leasing company the lease is assigned to and may not be negotiable. The factor you're offered depends on your credit and the leasing company's programs, and the first number quoted may not be the lowest you qualify for. Ways to push it down:

1. Ask directly. "Is this the lowest money factor the leasing company offers for my credit tier?"
2. Compare quotes. The CFPB says comparing several lease offers can get you a better deal. Convert each money factor.
3. Check special lease offers. Some lessors subsidize the rent charge, per the Federal Reserve. Read the fine print.
4. Ask about security deposits. Where offered, paying a larger refundable security deposit may lower your rent charge, according to the Federal Reserve.
5. Compare to a loan. Consumer Reports suggests that if the lease rate is more expensive than a loan rate you could get, try another leasing company or dealer.

One caution from the Federal Reserve: a lower rent charge isn't automatically a better deal if the capitalized cost is higher or the residual value lower. Compare the whole quote. For buying instead of leasing, see whether the dealer's loan rate is negotiable.

Negotiate the price first

The agreed-upon value of the vehicle is the main part of the gross capitalized cost, so the lower it is, the lower your payment (Federal Reserve). Consumer Reports recommends settling the price before you discuss leasing, in writing. See MSRP vs. invoice vs. out-the-door price.

Then check what else is in the gross capitalized cost. Service contracts and other products paid over the lease add to both depreciation and rent charge, and the Federal Reserve notes such optional services can be declined or negotiated. Our guide to dealer add-ons you can refuse covers the common ones.

Worked example (illustrative)

Using the Federal Reserve's numbers above and an assumed 36-month term, before taxes and fees:

• Adjusted capitalized cost $18,800, residual value $12,350. Depreciation: ($18,800 - $12,350) / 36 = about $179.17 a month.
• At a money factor of 0.00354 (about 8.5% using x 2,400), the rent charge is $110.27 a month, for a base payment of about $289.44.
• At a money factor of 0.00250 (about 6.0%), the rent charge is 0.00250 x $31,150 = about $77.88 a month, for a base payment of about $257.04.

That's about $32 a month, or about $1,166 over 36 payments, for the same car at the same price. Your numbers will differ.

A short email to send

Hi, I'm interested in leasing the [Year Make Model Trim], stock #[number], for [36] months at [12,000] miles a year. Before I visit, could you send an itemized lease quote in writing: the agreed-upon value (selling price), any fees or products included in the capitalized cost, the capitalized cost reduction, the residual value, the money factor, the base monthly payment, taxes, the total due at signing, and the total of payments? Please also confirm whether that money factor is the lowest available for my credit tier and whether any rebates are included. I'm comparing quotes from a few dealers. Thanks, [First name]

Check the lease before you sign

• Agreed-upon value matches your written quote, with no products you didn't agree to.
• Rent charge matches the quoted money factor, using the formula above.
• Residual value, term, and mileage match the quote. The FTC notes most standard leases allow 15,000 miles a year or less, with a fee for going over.
• Total of payments, amount due at signing, and early termination terms (the FTC warns these charges can be substantial).

Lease rules, taxes, and fees vary by state. If the paperwork doesn't match what you were promised, don't sign until it's fixed.

FAQ

What is a money factor on a car lease?

A small decimal, such as 0.00250, that many leasing companies use to calculate the rent charge (the lease version of interest) in your monthly payment. It's typically not disclosed, so ask for it.

How do you convert a money factor to APR?

Multiply it by 2,400 for a rough APR equivalent: 0.00250 x 2,400 = 6.0%. To go the other way, divide the rate by 2,400. It's an approximation for comparison, not an official APR.

Is the money factor on a lease negotiable?

Often, at least partly. The CFPB lists it among commonly negotiated lease terms, though the Federal Reserve notes the rent charge is often set by the leasing company. Ask whether the quoted factor is the lowest for your credit, and compare several quotes.

Why doesn't my lease show an interest rate?

There's no federal requirement for lessors to disclose a lease rate. Instead, the federal lease disclosure shows the rent charge in dollars. Under Regulation M, if a lessor does show a percentage rate, it must add a notice that the percentage may not measure the overall cost of financing the lease, and it can't call it an annual percentage rate.

Does a bigger down payment lower the money factor?

No. A larger capitalized cost reduction lowers the rent charge in dollars, but not the factor, and the Federal Reserve notes that money is nonrefundable once paid. Where offered, extra refundable security deposits may lower the rent charge instead.
