Understanding your auto lease results
Money factors vary with credit tier and manufacturer promotions. The table converts common money factors to APR so the financing cost can be compared with loan rates.
| Money factor | Implied APR | Context |
|---|---|---|
| 0.00042 | ≈1% | Subsidized promotional rate from a captive lender |
| 0.0025 | 6% | Worked-example rate — mid-range market pricing |
| 0.0042 | ≈10% | Higher-rate pricing, often weaker credit tiers or non-promoted models |
- The payment shown excludes sales tax, acquisition and disposition fees, registration, and charges for excess mileage or wear — all standard in real leases and disclosed under Regulation M.
- A large down payment on a lease carries a specific risk the FTC notes: if the car is totaled or stolen early, that up-front money is generally not recovered (gap coverage protects the loan/lease balance, not the down payment).
- The residual is contractual: if the market value at lease end is below the residual, returning the car makes the lessor bear the loss; if above, the buyout can be attractive.
- Educational estimate only — the lessor's Regulation M disclosure shows the binding figures.
What is an auto lease?
An auto lease is a contract to use a vehicle for a set term — commonly 24 to 39 months — paying for the depreciation the car undergoes plus a finance charge, then returning it or buying it at the pre-agreed residual value. The Federal Reserve's consumer guide to vehicle leasing and the FTC's leasing guidance both describe the payment as depreciation plus a 'rent charge' computed from the money factor.
The capitalized cost is the lease's equivalent of a purchase price and is negotiable; a down payment (formally a capitalized cost reduction) lowers it directly. The residual value is set by the lessor as a percentage of MSRP based on projected market value — around 50–60% is typical for a 36-month lease of a vehicle with average value retention, though it varies widely by model.
The money factor is the interest rate in disguise: multiplying it by 2400 gives the approximate APR. A money factor of 0.0025 corresponds to 6% APR. Dealers quote money factors in different formats (0.0025 vs '2.5'), so converting to APR is the reliable way to compare a lease's financing cost against a loan rate.
How to use this auto lease calculator
- Enter the vehicle's negotiated price / MSRP — the gross capitalized cost before reductions.
- Enter any down payment or trade-in credit (capitalized cost reduction); this can be zero.
- Enter the residual percentage from the lease quote — the projected lease-end value as a share of MSRP.
- Enter the term in months and the money factor from the quote (multiply by 2400 to check the APR).
- Read the monthly payment, the implied APR, the dollar residual value, and the total lease cost including the down payment.
- Worked example: a $30,000 vehicle with no down payment, a 60% residual ($18,000), 36 months, and a 0.0025 money factor (6% APR) costs $333.33 in depreciation plus $120.00 in rent charge — $453.33 per month and $16,320 in total.
The formula behind an auto lease payment
The net capitalized cost is the vehicle price minus the down payment. Depreciation spreads the difference between the net cap cost and the residual value over the term. The rent charge multiplies the sum of the net cap cost and residual by the money factor — the standard construction that charges the monthly rate on the average balance outstanding.
The implied APR is the money factor times 2400. Total lease cost adds the down payment back to the sum of all monthly payments, so up-front money is not hidden from the comparison.
Common mistakes
- Judging a lease by monthly payment alone — a longer term or bigger down payment lowers the payment without lowering the total cost.
- Not converting the money factor to APR (× 2400); a factor of 0.0035 sounds small but is an 8.4% financing rate.
- Putting a large down payment on a lease, which is at risk if the vehicle is totaled early and does not build equity as it would on a purchase.
- Ignoring the mileage allowance; excess-mileage charges of $0.15–$0.30 per mile can add thousands at turn-in.
- Negotiating only the payment rather than the capitalized cost — the cap cost is negotiable like a purchase price and drives the depreciation portion directly.
Häufig gestellte Fragen
How is a car lease payment calculated?
The payment is depreciation plus rent charge. Depreciation is the net capitalized cost (vehicle price minus down payment) minus the residual value, divided by the term in months. The rent charge is the net cap cost plus the residual, multiplied by the money factor. For a $30,000 car with a 60% residual over 36 months at a 0.0025 money factor: $333.33 + $120.00 = $453.33 per month before taxes and fees.
What is a good money factor?
Compare it as an APR: multiply the money factor by 2400. A factor of 0.0025 equals 6% APR, competitive with mid-range auto loan rates; factors near 0.001 (2.4% APR) reflect promotional subvention, while factors above 0.004 (9.6%+) are expensive financing. The money factor offered depends on credit tier and whether the manufacturer's captive lender is subsidizing the model.
What is the residual value on a car lease?
The residual value is the lessor's contractual estimate of the vehicle's worth at lease end, expressed as a percentage of MSRP — 60% on a $30,000 MSRP is $18,000. It determines the depreciation you pay (higher residual, lower payment) and is usually the price at which you may buy the car at lease end. Vehicles that hold value well lease more cheaply because their residuals are higher.
Is it better to put money down on a lease?
A down payment (capitalized cost reduction) lowers the monthly payment roughly proportionally, but it does not reduce the total cost much and carries a risk the FTC highlights: if the car is totaled or stolen early in the lease, the up-front money is generally not refunded. Many consumer guides therefore favor minimal down payments on leases, keeping the comparison focused on total lease cost.
Should I lease or buy a car?
Leasing pays for the vehicle's depreciation and returns it with no ownership; buying costs more per month but ends in an owned asset. Leasing tends to suit drivers who want a new vehicle every few years, drive within mileage limits, and value predictable costs; buying tends to win financially for those who keep vehicles long after the loan ends. This calculator quantifies the lease side; a loan calculator quantifies the purchase side for comparison.
What fees does a real lease add to this payment?
Typical additions include an acquisition fee at signing (often several hundred dollars), a disposition fee at turn-in, sales tax (applied per-payment or up-front depending on the state), registration, and potential charges for excess mileage or wear. The Consumer Leasing Act (Regulation M) requires these to be itemized in the lease disclosure before signing.
