Lease Calculator - Monthly Payment, Residual Value and Total Cost

Pick the price, set the residual, read your monthly payment

A lease splits the vehicle cost into two parts. Depreciation covers the value the car loses during the lease. The finance charge is interest on the average of what the car is worth now and what it will be worth at the end. Add them together, apply sales tax, and you get the monthly payment. This calculator does that arithmetic and shows where every dollar lands.

Example: $42,000 MSRP, 10% down, 55% residual, 4.8% APR, 36 months, 7% tax

$461/month

$298 depreciation + $131 finance charge + $32 tax

How to use this calculator - step by step

Vehicle price / MSRP ($) - the negotiated selling price. Always try to negotiate below sticker.
Down payment (%) - cash paid upfront that reduces the capitalized cost. 0-20% is typical. Zero-down leases exist but cost more monthly.
Lease term (months) - 24, 36, 39 or 48 months. 36 is the most common. Shorter = higher payment but less total cost.
Residual value (%) - what the car is worth at lease end, as a percentage of MSRP. Set by the lessor. Higher = lower payment.
Annual interest rate (%) - the APR equivalent. If you have a money factor (e.g. 0.00125), multiply by 2400 to convert (0.00125 x 2400 = 3.0%).
Sales tax (%) - state and local tax applied to each monthly payment. Set to 0% if tax is already included or not applicable.
Read the results - monthly payment (pre-tax and total), depreciation vs finance charge split, and total lease cost.

How residual value and term affect the payment

Reference: $40,000 vehicle, 10% down, 5% APR, 0% tax.

Term	Residual 45%	Residual 55%	Residual 65%
24 months	$581/mo	$381/mo	$181/mo
36 months	$430/mo	$319/mo	$208/mo
48 months	$363/mo	$288/mo	$213/mo

A 10-percentage-point increase in residual value drops the 36-month payment by roughly $111. The residual is the single biggest lever on your lease payment - bigger than the rate, bigger than the down payment.

Practical examples

$35,000 sedan, 0% down, 55% residual, 3.6% APR, 36 months, 6% tax - depreciation: $438/mo, finance: $91/mo, tax: $32/mo. Total payment: $560/mo. Total lease cost: $20,173. Zero-down leases are convenient but the full depreciation hits the monthly payment.

$48,000 SUV, 15% down, 50% residual, 5.5% APR, 36 months, 8% tax - cap cost: $40,800, depreciation: $467/mo, finance: $170/mo. Total payment: $688/mo. Total cost with down payment: $31,960. The 15% down keeps the monthly under $700 on a $48k vehicle.

$28,000 compact, 10% down, 60% residual, 2.4% APR, 24 months, 0% tax - depreciation: $420/mo, finance: $53/mo. Total payment: $473/mo. Total cost: $14,152. High residual and low rate make this a cheap way to drive a new car for 2 years.

$65,000 luxury, 10% down, 52% residual, 6.0% APR, 36 months, 9% tax - depreciation: $578/mo, finance: $249/mo. Total payment: $902/mo. Total cost: $38,958. On luxury vehicles the finance charge becomes a significant part of the payment.

$42,000 EV, 5% down, 48% residual, 4.2% APR, 48 months, 7% tax - depreciation: $388/mo, finance: $124/mo. Total payment: $548/mo. Total cost: $28,394. EVs often have lower residuals due to rapid technology changes, which pushes the payment up despite incentives.

FAQ - Frequently asked questions

What is a money factor and how do I convert it?

A money factor is the lease equivalent of an interest rate, expressed as a tiny decimal (e.g. 0.00125). Multiply by 2400 to get the equivalent APR: 0.00125 x 2400 = 3.0% APR. Dealers sometimes quote money factors to make the financing cost look small. Always convert to APR for comparison with loan rates.

Is it better to lease or buy?

Leasing is cheaper per month but you never own the car. Over 6 years: leasing two 3-year terms on a $40,000 car at 55% residual costs roughly $36,000 in total payments with nothing at the end. Buying the same car with a 6-year loan at 6% costs about $46,000 but you own a car worth $16,000-20,000. Net cost of buying: $26,000-30,000. Leasing wins on cash flow; buying wins on total cost if you keep the car.

Should I put money down on a lease?

A down payment lowers the monthly bill but does not reduce the total finance charge. Worse: if the car is totaled in month 3, insurance pays the current market value - you lose your down payment. Financial advisors generally recommend zero or minimal down on leases and paying the higher monthly instead. Use gap coverage if offered.

What is a good residual value?

For a 36-month lease: 55-65% is strong, 45-55% is average, below 45% means heavy depreciation and expensive monthly payments. Trucks and SUVs from Toyota, Lexus and Honda tend to have the highest residuals. Luxury sedans and EVs tend to depreciate faster. The residual is set by the lessor and is usually not negotiable.

What fees are not included in this calculator?

This calculator covers the core lease math: depreciation, finance charge and sales tax. Real-world leases may also include an acquisition fee ($595-995), disposition fee ($300-500 at lease end), excess mileage charges ($0.15-0.30/mile), wear-and-tear charges and early termination fees. Ask the dealer for the full cost breakdown before signing.

Can I buy the car at the end of the lease?

Yes - the buyout price is typically the residual value plus a purchase option fee ($200-500). If the car's market value exceeds the residual, buying out is a good deal. If it is worth less, return it and walk away. Check your contract for the exact buyout terms and any additional fees.
