Ever seen a number like "0.00125" on a lease quote and wondered what it means? That's the money factor—basically the interest rate on your lease, just written in a confusing way.
Why so confusing? Some say it's designed that way. The result: most people have no idea if they're getting a good deal—and that confusion can cost you $1,500 or more.
Quick Summary (TL;DR)
- • Money factor is the interest rate on a lease, expressed as a small decimal
- • Multiply by 2,400 to convert to APR
- • A "good" money factor in 2025 is typically 0.00100-0.00180 (2.4%-4.3% APR)
- • Dealers legally mark up money factor without disclosure—costing you $500-$1,500+
💰 Real Example: How Much You Could Save
2025 BMW X3 xDrive30i — MSRP $52,000, 36-month lease:
At Dealer's Rate (0.00225 = 5.4% APR)
$649/mo
At Base Rate (0.00125 = 3.0% APR)
$598/mo
Savings: $51/month × 36 months = $1,836 — just by knowing the base rate.
1Money Factor Explained Simply
Money factor (MF) is a way to express the financing cost of a lease. While traditional auto loans use an interest rate like "5.9% APR," leases use a money factor like "0.00125."
Why the weird format? Some say it was designed to make it harder for consumers to compare lease rates to loan rates. Others say it's just a quirk of how lease calculations evolved. Either way, the result is the same: most people have no idea if they're getting a good rate.
Here's what a money factor represents:
The "Rent Charge" Portion of Your Lease Payment
Your monthly lease payment has two main parts: depreciation (the value the car loses) and the rent charge (basically interest). The money factor determines the rent charge. The higher the money factor, the more you pay in financing costs every month.
2How to Convert Money Factor to APR
The magic number is 2,400. To convert any money factor to an equivalent APR, simply multiply by 2,400.
The Formula
Examples:
| Money Factor | Calculation | Equivalent APR |
|---|---|---|
| 0.00100 | 0.00100 × 2,400 | 2.4% |
| 0.00175 | 0.00175 × 2,400 | 4.2% |
| 0.00250 | 0.00250 × 2,400 | 6.0% |
| 0.00350 | 0.00350 × 2,400 | 8.4% |
Now you can compare a lease's money factor directly to a traditional auto loan rate. If a dealer offers you a money factor of 0.00250 (6% APR) but you could get a loan at 4.5%, you know you're overpaying.
3What's a Good Money Factor in 2025?
A "good" money factor depends on current market conditions and the manufacturer. With interest rates stabilizing in 2025, here's an updated guide:
Excellent
0.00001 - 0.00125
0% - 3.0% APR
Special programs, loyalty offers, EVs
Average (2025)
0.00125 - 0.00220
3.0% - 5.3% APR
Standard manufacturer base rates
High (Marked Up)
0.00220+
5.3%+ APR
Likely includes dealer profit margin
📊 2025 Base Rates by Brand (Examples)
Toyota/Lexus
~0.00125
BMW/Mercedes
~0.00150
Honda/Acura
~0.00140
EVs (Incentivized)
~0.00083
* Rates vary by model, term, and credit tier. Always verify with manufacturer lease programs.
Key insight: The best benchmark is the manufacturer's "base" or "buy rate" money factor. This is what the manufacturer's captive finance company (like Toyota Financial, BMW Financial Services, etc.) charges. Anything above that is dealer profit.
4How Dealers Mark Up Money Factor
The Dirty Secret
Dealers can mark up your money factor without telling you—and they get to keep the difference. Unlike loan APR, there's no federal requirement to disclose the base rate or the markup on a lease.
Here's how it works:
- 1. Manufacturer sets a base rate: Let's say BMW's base money factor for a 3 Series is 0.00125 (3.0% APR).
- 2. Dealer marks it up: The dealer adds 0.0005 to make it 0.00175 (4.2% APR).
- 3. You never know: The dealer just quotes you "the money factor is 0.00175" without mentioning the base rate.
- 4. Dealer profits: On a $50,000 lease, that 0.0005 markup earns the dealer roughly $800-1,200 in extra profit.
This is 100% legal, and many dealers consider it standard practice. The only way to fight back is to know the base rate before you negotiate.
5How to Find Manufacturer Base Rates
Finding the actual base money factor takes some effort, but it's worth it. Here are your options:
📊 Edmunds Forums
The Edmunds "Prices Paid" forums often have users sharing current base rates. Search for your specific vehicle and current month.
🚗 Leasehackr
The Leasehackr community tracks money factors for most brands. Their "calculator" and forums are excellent resources.
📞 Call the Captive Lender
You can call BMW Financial Services, Toyota Financial, etc. directly and ask for current base rates on specific vehicles.

Using money factor to your advantage
Money factor is deliberately confusing—but now you know the truth. When leasing:
- 1. Always ask for the money factor (many dealers won't volunteer it)
- 2. Multiply by 2,400 to see the real APR
- 3. Research the base rate before negotiating
- 4. Demand the base rate or walk away
The money factor is one number, but it accounts for a large fraction of total lease cost. Knowing the buy rate before you sit down is the most useful thing you can do.
