What This Lease Calculator Does
This calculator estimates a monthly lease payment for an asset using four inputs: value, residual value, money factor, and term. It is useful for comparing simplified equipment, vehicle, or asset-lease scenarios before you review a full contract.
Core Lease Formula
Where:
- — asset value or capitalized cost
- — residual value
- — lease term in months
- — money factor
- — monthly depreciation
- — monthly finance charge
The equivalent APR shown in the result is a comparison shortcut:
Worked Example
For an asset worth 30,000, residual value 15,000, money factor 0.003, and term 36 months:
| Component | Calculation | Result |
|---|---|---|
| Monthly depreciation | (30,000 - 15,000) ÷ 36 | 416.67 |
| Monthly finance charge | (30,000 + 15,000) × 0.003 | 135.00 |
| Monthly lease payment | 416.67 + 135.00 | 551.67 |
A higher residual value reduces depreciation, while a higher money factor increases the finance charge.
What This Simplified Estimate Leaves Out
Real lease contracts may include taxes, fees, maintenance obligations, insurance, service packages, deposits, purchase options, and early-termination rules. Some leases also structure payments differently from this simple comparison model.
Use the result as a planning estimate, then read the contract language before making a decision.
How to Read the Result
If the depreciation share is large, the asset is losing much of its value during the lease. If the finance charge share is large, the money factor is doing most of the work. Compare those two pieces before focusing on the monthly payment alone.
Frequently asked questions
What does residual value mean in a lease?
Residual value is the asset value expected to remain at the end of the lease. A higher residual value lowers the depreciation portion of the payment because less value is being used up during the contract.
What is a money factor?
A money factor is the lease finance charge input. Multiplying it by 2,400 gives a rough APR comparison, which helps when you want to compare one lease offer with another.
Why can two leases with the same asset value have different payments?
Because the payment depends on more than the starting value. A different residual value, money factor, term, or fee structure can change the monthly cost materially.
When should I use a loan calculator instead?
Use a loan calculator when you are financing ownership rather than temporary use. Loans amortize the financed balance toward zero, while a lease usually ends with a residual value still remaining.
