Calculate monthly car lease payments. Break down depreciation, finance charges, and taxes with money factor comparison, term analysis, and due-at-signing totals.
Leasing a car means paying for depreciation rather than the full purchase price, but the math can still be easy to misread. Unlike a loan, lease payments are driven by the money factor (interest), residual value (predicted future value), and the negotiated capitalized cost.
Your monthly lease payment has three components: depreciation (the difference between the negotiated price and residual value, divided by months), a finance charge (based on the money factor, which is essentially interest), and sales tax. The money factor looks tiny — 0.00150 seems like nothing — but multiply by 2400 to get the equivalent APR of 3.6%. That conversion is crucial for comparison shopping.
This calculator breaks down every cent of your lease payment, showing exactly how much goes to depreciation, finance charges, and tax. It compares different lease terms (24 to 48 months), different money factors (interest rates), and shows your total cost of leasing including the often-forgotten due-at-signing amount. Use it before walking into a dealership to know exactly what you should be paying.
Use this to separate lease payment components before you negotiate. It shows how price, residual value, money factor, and taxes interact so you can compare offers on the same terms.
Monthly Depreciation = (Net Cap Cost − Residual Value) ÷ Term Monthly Finance Charge = (Net Cap Cost + Residual Value) × Money Factor Monthly Payment = (Depreciation + Finance) × (1 + Tax Rate) Effective APR = Money Factor × 2400 Net Cap Cost = Negotiated Price + Fees − Down − Trade − Rebates Residual Value = MSRP × Residual %
Result: Monthly Payment: $586.61 — Total Cost: $24,118 — APR: 3.6%
Residual = $42,000 × 50% = $21,000. Net cap cost = $39,500 + $900 fees − $3,000 down = $37,400. Depreciation = ($37,400 − $21,000) ÷ 36 = $455.56/mo. Finance = ($37,400 + $21,000) × 0.00150 = $87.60/mo. Pre-tax = $543.16. Tax at 8% = $43.45. Total = $586.61/mo. Over 36 months that is about $21,118, and adding the $3,000 due at signing brings total outlay to about $24,118.
A small change in money factor or negotiated price can materially change the monthly payment over a 36-month term.
Compare offers using the same MSRP, residual percentage, fees, and tax assumptions so the results stay comparable.
A large down payment rarely improves lease economics and can increase risk if the vehicle is totaled or stolen early in the term.

This calculator builds a standard lease-payment worksheet from depreciation, rent charge, taxes, fees, and due-at-signing amounts. It also converts the money factor to an approximate APR so shoppers can compare the lease financing cost against a traditional loan.
The result is a planning estimate, not the dealer contract. Actual contracts can differ because of state taxes, acquisition fees, rebates, mileage terms, and lender-specific lease rules.
The money factor is the lease equivalent of an interest rate, expressed as a tiny decimal (like 0.00150). Multiply by 2400 to get the approximate APR: 0.00150 × 2400 = 3.6%. Dealers sometimes quote it as 1.5 (multiplied by 1000). Always ask for the actual money factor — dealers aren't required to disclose it in many states.
The predicted value of the car at lease end, expressed as a percentage of MSRP. A 50% residual on a $40,000 car means it's expected to be worth $20,000 after the lease. Higher residual = lower payment. Residuals are set by the bank, not the dealer, and aren't negotiable.
Generally NO. If the car is totaled or stolen, your insurance pays the bank — and your down payment is gone. Unlike a purchase, a lease down payment just pre-pays depreciation. Instead, negotiate a lower selling price to reduce the monthly payment without the risk.
You pay the excess mileage fee at lease return — typically $0.15-$0.30 per mile. Going 5,000 miles over at $0.25/mile = $1,250 penalty. If you expect higher mileage, negotiate a higher limit upfront (10,000 → 15,000 miles/year) — it's much cheaper than the penalty.
Leasing costs less per month but you never build equity. Over 10 years: leasing a new car every 3 years costs ~40-60% more than buying and keeping for 10 years. Leasing makes financial sense if you want a new car every 2-3 years anyway, need the tax deduction (business use), or want to minimize maintenance costs.
Absolutely. The negotiated price (capitalized cost) is the most important number in any lease. Negotiate it exactly like a purchase price — research invoice prices, get competing quotes, and aim for 4-8% below MSRP. Every $1,000 off the price saves roughly $28/month on a 36-month lease.
