What Is Money Factor? The Hidden Number in Every Car Lease

What Is Money Factor?

Money factor is the financing charge built into every car lease. It works like an interest rate, but it is expressed as a tiny decimal number instead of a percentage. Dealerships and leasing companies use money factor rather than APR because the lease payment calculation is different from a traditional loan, but the two are directly related.

To convert a money factor to an equivalent APR, multiply it by 2,400. To go the other direction, divide the APR by 2,400.

• 0.00125 money factor = 3.0% APR
• 0.00083 money factor = roughly 2.0% APR
• 0.00042 money factor = roughly 1.0% APR
• 0.00001 money factor = roughly 0.024% APR (essentially zero-interest)

The number 2,400 comes from the fact that a standard lease payment formula effectively doubles the rate and then divides by 12 months, so 2 x 12 x 100 = 2,400.

How Money Factor Affects Your Monthly Payment

Every lease payment has two main components: the depreciation charge (the portion of the car's value you use up) and the finance charge (the cost of borrowing the money). The money factor controls the finance charge.

The finance charge each month is calculated as:

(Capitalized Cost + Residual Value) x Money Factor

Because the formula adds the full cap cost to the full residual, even a small change in the money factor can swing your payment by a meaningful amount. On a vehicle with a $40,000 cap cost and a $24,000 residual, the sum is $64,000. Every 0.0001 increase in money factor adds $6.40 per month -- roughly $230 over a 36-month lease.

A Real Calculation Example

Suppose you are leasing a vehicle with the following terms:

• MSRP: $42,000
• Negotiated price (capitalized cost): $40,000
• Residual value: $25,200 (60% of MSRP after 36 months)
• Money factor: 0.00125 (3.0% APR)
• Lease term: 36 months

Step 1 -- Depreciation charge

($40,000 - $25,200) / 36 = $411.11 per month

Step 2 -- Finance charge

($40,000 + $25,200) x 0.00125 = $81.50 per month

Step 3 -- Total base payment

$411.11 + $81.50 = $492.61 per month (before tax)

Now compare: if you qualified for a manufacturer-subsidized money factor of 0.00042 (about 1.0% APR) instead, the finance charge drops to just $27.38 per month. That is a savings of roughly $54 every month, or over $1,940 across the full lease -- without changing the sale price or residual at all.

What Counts as a Good Money Factor?

Money factor benchmarks shift with broader interest-rate conditions, but as a general guide:

• Excellent: 0.00042 or below (1.0% APR or less) -- usually a manufacturer-subsidized rate
• Good: 0.00083 to 0.00125 (2.0% to 3.0% APR) -- competitive for most credit tiers
• Average: 0.00125 to 0.00188 (3.0% to 4.5% APR)
• High: 0.00208 and above (5.0% APR+) -- worth pushing back or shopping around

Your credit score plays a big role. Tier-1 credit (typically 720+) qualifies for the best rates. If the dealer quotes a money factor well above the buy rate for your tier, there may be a markup baked in.

How to Find Out the Money Factor on a Deal

Dealerships are not required to disclose the money factor, and many lease worksheets show only the monthly payment. Here is how to uncover it:

• Ask directly. Request the money factor in writing. A reputable dealer will share it.
• Back-calculate it. If you know the cap cost, residual, and monthly payment, subtract the depreciation portion from the payment. The remainder is the finance charge. Divide that by (cap cost + residual) to get the money factor.
• Check forums and rate sheets. Sites like Edmunds forums often publish the current base (buy) money factors from each manufacturer's captive lender. Compare those to what the dealer offers.

If the dealer's money factor is higher than the published buy rate, the difference is a dealer markup on the rate -- and it is negotiable.

How to Negotiate a Lower Money Factor

Unlike the vehicle's sale price, the money factor is set by the leasing company (usually the manufacturer's captive finance arm), so the dealer has limited room to lower it below the buy rate. However, you can still take steps to get the best possible number (see our full guide on how to negotiate a car lease for more strategies):

• Know the buy rate before you visit. Research the current base money factor for the exact model, term, and mileage tier you want.
• Refuse dealer markup. If the quoted money factor exceeds the buy rate, ask the dealer to match the base rate. This is the single most common hidden profit center in a lease.
• Target manufacturer lease specials. Automakers frequently subsidize the money factor to move specific models. A subsidized rate can drop the effective APR to 1% or even 0%, saving you hundreds over the lease.
• Maintain strong credit. The best money factors are reserved for top credit tiers. Pull your credit report before shopping so there are no surprises.
• Compare across brands. If two vehicles meet your needs, the one with a lower subsidized money factor may cost significantly less to lease even if the sticker prices are similar.

Money Factor vs. APR -- Quick Reference

Keep this conversion handy when reviewing any lease offer:

• Money Factor x 2,400 = APR
• APR / 2,400 = Money Factor

Whenever you see a lease payment, ask what money factor was used. Converting it to APR instantly tells you whether the financing cost is reasonable compared to current auto-loan rates. Keep in mind that the money factor is only one piece of the total cost — our guide on advertised vs. actual lease payments explains what else can change the number you actually pay.
