Key Takeaways
Option A
Auto Loan Payment
You're paying to own — principal plus interest across the full vehicle value.
Best for: Drivers who want to build equity, have no mileage restrictions, and plan to keep the vehicle long-term.
Option B
Lease Payment
You're paying for depreciation only — the portion of the car you actually use.
Best for: Drivers who prefer lower monthly outlays, change vehicles frequently, and stay within set mileage limits.
If you drive more than 15,000 miles per year
Auto Loan Payment
Lease agreements impose per-mile overage charges — commonly $0.15–$0.25 per mile — that can eliminate any payment advantage and produce a large bill at turn-in.
If you prioritize the lowest possible monthly cash outflow
Lease Payment
Because you're financing only depreciation rather than the full purchase price, lease payments are typically 20–30% lower than a comparable loan payment for the same vehicle.
If you plan to keep the vehicle beyond five years
Auto Loan Payment
Once the loan is paid off, your monthly transportation cost drops to insurance and maintenance. A lease cycle restarts costs every two to three years indefinitely.
If you want to customize or modify the vehicle
Auto Loan Payment
Leased vehicles must be returned in near-original condition. Modifications are generally prohibited or must be reversed at your expense before turn-in.
If you value a predictable, warranty-covered payment period every few years
Lease Payment
Lease terms typically align with the manufacturer warranty window, meaning most mechanical repairs fall under warranty coverage throughout the agreement.
How a Loan Payment Is Calculated
An auto loan payment is built on a straightforward amortization formula. The lender finances the full purchase price of the vehicle — minus any down payment or trade-in credit — and then spreads principal repayment plus interest across the loan term.
The core variables are: loan amount (capitalized cost minus down payment), annual percentage rate (APR), and loan term in months. The standard amortization formula produces a fixed monthly payment where early payments are interest-heavy and later payments are increasingly principal-heavy.
For example, a $35,000 loan at 6.5% APR over 60 months produces a monthly payment of roughly $685. By the final payment, the borrower has paid approximately $6,100 in interest in addition to the principal. Every payment builds equity — the gap between what you owe and what the vehicle is worth.
Understanding the short-term versus long-term value tension is essential here: higher loan payments feel costlier month-to-month but produce an asset you own outright.
| Criterion | Auto Loan Payment | Lease Payment |
|---|---|---|
| What you're financing | Full vehicle price | Depreciation only |
| Key rate variable | APR (e.g., 6.5%) | Money factor (e.g., 0.00150) |
| Residual value role | Not applicable | Central — directly lowers payment |
| Typical monthly cost | Higher (full amortization) | Lower (20–30% less on average) |
| Equity built | Yes — increases each month | None |
| Mileage restrictions | None | Yes — overage fees apply |
| End-of-term outcome | You own the vehicle outright | Return or purchase at residual |
| Negotiable price component | Yes — selling price | Yes — cap cost and money factor |
How a Lease Payment Is Calculated
A lease payment is structurally different because you are not financing the full vehicle — you are financing its projected depreciation during the lease term, plus a finance charge on the outstanding balance.
Three numbers define the calculation:
- Capitalized cost: The negotiated selling price of the vehicle (and yes, this is negotiable on most leases).
- Residual value: The vehicle's projected worth at lease end, expressed as a percentage of MSRP set by the leasing company. A $40,000 vehicle with a 55% residual has a $22,000 residual value.
- Money factor: The lease equivalent of an interest rate, expressed as a small decimal (e.g., 0.00125). Multiply by 2,400 to convert to an approximate APR equivalent — so 0.00125 equals roughly 3% APR.
The monthly depreciation charge is simply: (Capitalized Cost − Residual Value) ÷ Lease Term. The finance charge is: (Capitalized Cost + Residual Value) × Money Factor. These two figures added together produce the base monthly payment before taxes and fees.
Using the same $40,000 vehicle with a 55% residual, a 36-month term, and a money factor of 0.00150: depreciation = ($40,000 − $22,000) ÷ 36 = $500/month; finance charge = ($40,000 + $22,000) × 0.00150 = $93/month. Base payment: $593 — meaningfully lower than a comparable loan.
Hidden fees in lease agreements — acquisition charges, disposition fees, and excess wear costs — can erode this payment advantage significantly.

Average monthly payment gap (lease vs. loan)
Experian's State of the Automotive Finance Market data has historically shown lease payments running roughly $100–$150/month lower than loan payments for comparable vehicles.
55–65%
Typical residual value range for popular vehicles
Residual percentages vary by vehicle segment; trucks and SUVs with strong resale history tend to carry higher residuals, directly reducing lease payments.

Money factor conversion multiplier to approximate APR
Multiplying the money factor by 2,400 gives a useful approximation of the equivalent annual percentage rate for comparison with loan offers.
What the Formulas Reveal About Long-Term Cost
The math exposes a trade-off that's easy to miss in a showroom. Leases offer lower monthly payments because the residual value acts as a large deferred balance you never pay — instead, you return the vehicle. That residual represents value you don't capture.
Over a 10-year period, someone who continuously leases 36-month terms will have paid for roughly 3.3 vehicles while owning none of them. A buyer who loans a vehicle for 60 months and keeps it for 10 years pays it off, then drives payment-free for five years — a period with substantial cash flow relief.
The full financial picture of buying vs leasing explores this 10-year comparison in greater depth, including how maintenance costs and depreciation curves shift the outcome.
Your driving behavior also reshapes the math materially. How driving habits affect the leasing vs buying calculation shows that high-mileage drivers can face thousands in overage charges that effectively close the payment gap entirely.
The Residual Is Set by the Lessor, Not the Market
Residual values in a lease are determined by the leasing company (often the automaker's captive finance arm) based on proprietary depreciation models — not live market data. A higher residual reduces your monthly payment but does not guarantee the vehicle will actually be worth that much at turn-in. If the market value falls below the residual, you have no financial stake in the difference because you don't own the vehicle. If it exceeds the residual, you have the option to purchase at the contracted price, which can occasionally represent favorable terms — though this is not guaranteed.
