When leasing a vehicle, one of the most confusing yet important terms you will encounter is the money factor. It’s essentially the leasing equivalent of an interest rate and directly affects your monthly payments. Understanding how the money factor works — and how to calculate it — can save you a significant amount of money over the lease term.
Lease Money Factor Calculator
What is the Lease Money Factor?
The money factor is a small decimal number that represents the financing charge on your lease. While it works similarly to an interest rate in a car loan, it’s expressed differently.
To convert a money factor to an annual percentage rate (APR), you multiply it by 2400. For example:
- Money Factor: 0.0025
- APR = 0.0025 × 2400 = 6%
A lower money factor means you’ll pay less in interest charges over the life of your lease.
How to Use the Lease Money Factor Calculator
Using our Lease Money Factor Calculator is straightforward. Here’s a step-by-step guide:
- Enter the monthly payment amount
Input your expected or quoted monthly lease payment. - Enter the lease term (in months)
Provide the total duration of the lease (e.g., 24, 36, or 48 months). - Enter the capitalized cost
This is the agreed-upon value of the car plus any additional fees. - Enter the residual value
The estimated value of the car at the end of the lease term. - Enter any down payment or trade-in value
This reduces the amount being financed. - Calculate
The tool will display your money factor, equivalent APR, and interest charges.
Formula for Lease Money Factor
The Lease Money Factor can be calculated using the formula:
Money Factor = (Monthly Payment – Depreciation Portion) ÷ (Net Cap Cost + Residual Value)
Where:
- Depreciation Portion = (Net Cap Cost – Residual Value) ÷ Lease Term
- Net Cap Cost = Capitalized Cost – Down Payment/Trade-In
Example Calculation
Let’s say:
- Monthly Payment = $350
- Lease Term = 36 months
- Capitalized Cost = $25,000
- Residual Value = $15,000
- Down Payment = $2,000
Step 1: Net Cap Cost = $25,000 – $2,000 = $23,000
Step 2: Depreciation Portion = ($23,000 – $15,000) ÷ 36 = $222.22
Step 3: Interest Portion = $350 – $222.22 = $127.78
Step 4: Money Factor = $127.78 ÷ ($23,000 + $15,000) = 0.00295
Step 5: Equivalent APR = 0.00295 × 2400 = 7.08%
Result: Money Factor = 0.00295 (7.08% APR)
Why the Money Factor Matters
The money factor may seem small, but even slight changes can significantly impact your monthly payment and total lease cost. For example, lowering the money factor from 0.0025 to 0.0015 on a $30,000 car could save you thousands over the lease term.
Tips to Get a Better Money Factor

- Shop around – Compare offers from multiple dealerships and leasing companies.
- Negotiate – The money factor can be negotiated just like the car’s price.
- Lease during promotions – Manufacturers often offer lower rates during sales events.

Common Mistakes When Calculating the Money Factor
- Forgetting to subtract the down payment from the capitalized cost.
- Using the wrong residual value from the lease agreement.
- Confusing APR and money factor without conversion.
- Ignoring fees that may affect the cap cost.
