About Car Lease Calculator — Payment from Money Factor
A lease payment is two charges stapled together: DEPRECIATION — the slice of (negotiated price minus residual value) you consume each month — and the FINANCE charge, computed with the lease world's deliberately opaque 'money factor' on the SUM of net cap cost and residual (you pay to finance the whole car's value, not just the part you use, because the lessor's capital is tied up in all of it). At the defaults, the payment splits roughly 70/30 between depreciation and finance. Money factor is an APR wearing camouflage: multiply by 2400 and the costume falls off — 0.00275 is 6.6% APR. Dealers quote MF to four decimals precisely because 0.00275 sounds like nothing; ask for the money factor explicitly, convert it, and compare against your auto-loan offers. MF is also where marked-up profit hides: your credit tier qualifies for a 'buy rate' that dealers may quietly raise. Everything in a lease negotiates exactly like a purchase: the cap cost (price), the MF (rate) — only the residual is fixed by the leasing company. The residual percentage explains why some cars lease brilliantly and others terribly: a 58% three-year residual means you pay for 42% of the car; a luxury sedan with a 45% residual makes you pay for 55% of a pricier car — leasing favors slow depreciators. One contrarian warning baked into the math: large DOWN payments on leases are riskier than on purchases — if the car is totaled in month 6, gap coverage makes the lender whole but your cap-cost reduction is simply gone. Low-drive-off, slightly-higher-payment structures carry less of this risk.

Frequently asked questions
What's a good money factor?+
Convert to APR first (MF × 2400) and compare to current auto-loan rates for your credit tier — a lease should finance within ~0.5–1% of a loan. 0.00125 ≈ 3% APR is excellent; 0.00275 ≈ 6.6% is market-typical recently; 0.004+ ≈ 9.6% means a marked-up MF or rough credit — ask what the BUY RATE is and negotiate the markup. Captive lenders (the automaker's finance arm) often subsidize MF on models they want moved; that subsidy is the entire reason some leases beat buying.
Lease or buy — what does this math say?+
Leasing rationally wins when: the model holds value (high residual), the manufacturer subsidizes the MF, you genuinely replace cars every 2–3 years, or business use makes payments deductible. Buying wins for keepers — total cost of two consecutive 3-year leases almost always exceeds owning the same car six years. The honest comparison: this calculator's total lease cost vs (loan payments − resale value after the same months). Run both before the showroom, not in it.
What happens at the end of the lease?+
Three doors: return it (pay disposition fee ~$350–$500 plus excess wear/mileage — typically $0.15–$0.30 per mile over), BUY it at the residual stated in your contract (a bargain whenever used-market value exceeds the residual — check both numbers a month before turn-in), or roll into a new lease (where dealers love burying unpaid balances). The buyout comparison is the one that's free money when used prices spike: a contract residual is a price LOCK the market sometimes beats.
Why do lease ads say '$0 down' but $2,000 'due at signing'?+
Drive-off costs ≠ down payment: first month's payment, acquisition fee (~$650–$895), registration and doc fees are due regardless and are NOT cap-cost reduction. A true down payment (cap reduction) lowers the monthly by down ÷ term plus a little finance saving — $2,000 over 36 months is ~$58/month, so the advertised-low payment with big drive-off is the same money rearranged. Compare leases on TOTAL cost (this calculator's output), never the monthly alone.
