What is a money factor?

The money factor is the lease equivalent of an interest rate. Multiply the money factor by 2,400 to convert to approximate APR. Examples: money factor 0.0015 = 3.6% APR; 0.002 = 4.8% APR; 0.003 = 7.2% APR (high). Money factor is usually expressed as a decimal (0.00xx). Always ask the dealer for the money factor explicitly — they may not volunteer it. Dealers can mark up the money factor; ask "what's the buy rate from the manufacturer captive lender?" to identify markup.

What is residual value?

Residual value is the predicted value of the vehicle at lease end, expressed as a percentage of MSRP. Higher residual = lower depreciation cost = lower monthly payment. Residuals are set by the leasing lender based on historical depreciation data. Vehicles with strong resale value (Toyota, Honda, certain trucks) have higher residuals. Manufacturer-subsidized leases artificially inflate residuals to make luxury leases competitive. Typical 36-month residuals: 50-60% for mass-market vehicles, 55-65% for trucks/SUVs, 50-65% for luxury (often subsidized).

Should I put money down on a lease?

Generally no, beyond the first month's payment and required initial fees. If the car is totaled or stolen, insurance pays the leasing company directly and you lose any down payment. Down payments also don't build equity — you don't own the car. Exception: if you need a down payment to qualify for a subvented (manufacturer-subsidized) rate, the math may favor it. Otherwise, negotiate a lower cap cost or money factor rather than putting cash down.

Is leasing or buying cheaper?

Depends on time horizon and vehicle. Leasing is typically cheaper monthly for the first 36-48 months. Buying (especially financing) is typically cheaper long-term (5+ years) because you build equity and stop making payments after the loan is paid off. Heavy decision factors: how long you keep vehicles (lease wins for ≤3 years, buy wins for ≥5 years), tax deductibility (lease often better for business use), and whether the vehicle holds value (lease better for fast-depreciating luxury). Use lease-vs-buy calculator for head-to-head comparison.

What happens at the end of a car lease?

Three options: (1) Return the vehicle — pay disposition fee ($300-$500), excess mileage charges if over limit, and excess wear-and-tear charges. (2) Buy the vehicle at the residual value (plus sales tax) — sometimes a good deal if residual is below market value. (3) Lease another vehicle from the same brand — disposition fee often waived. The typical pattern: return the vehicle and start a new lease (locks you into the lease cycle indefinitely with no equity accumulation). Returning and buying used elsewhere is often more economical than serial leasing.

Car Lease Payment Calculator

Estimate your car lease payment by entering the MSRP, negotiated price, residual value percentage, and money factor. See the breakdown of depreciation, finance charges, and taxes in your monthly payment.

Car leasing is essentially a long-term rental: you pay for the vehicle's expected depreciation during the lease term, plus a finance charge (money factor) and taxes. At lease end, you return the vehicle or buy it out at the predetermined residual value. The structure makes leases monthly-payment-friendly compared to financing (you're paying for only a portion of the car), but typically more expensive over the long run because you never own anything.

Leases involve unfamiliar terminology that dealers can use to obscure the deal. Key terms: **capitalized cost** (the negotiated price), **cap cost reduction** (down payment that lowers the cap cost), **residual value** (predicted value at lease end, expressed as % of MSRP), **money factor** (the lease equivalent of interest rate — multiply by 2,400 for approximate APR), and **acquisition/disposition fees** (lender charges). All of these are negotiable to varying degrees. Most consumers don't realize the negotiated price (cap cost) is negotiable in leasing exactly as in purchasing, and dealers profit when buyers focus only on monthly payment.

This calculator computes the monthly lease payment given all the inputs, broken down into depreciation cost, finance charge, and taxes. Use it to: verify dealer-quoted lease numbers, model how negotiating each variable affects monthly payment, and compare leases across vehicles and lease structures. Leasing makes financial sense in narrow circumstances: short-term needs (1-3 years), heavy business-use vehicles where tax deductibility offsets cost, and luxury vehicles where lease residuals are subsidized by manufacturers. For most personal-use buyers planning to keep a vehicle 5+ years, buying (especially used) is meaningfully cheaper than the lease-trade-lease cycle.

Formula

Monthly lease payment formula: Monthly Payment = Depreciation Fee + Finance Fee + Tax Depreciation Fee = (Adjusted Cap Cost − Residual Value) / Lease Term Months Finance Fee = (Adjusted Cap Cost + Residual Value) × Money Factor Tax = (Depreciation Fee + Finance Fee) × Sales Tax Rate Where: Adjusted Cap Cost = Negotiated Price − Down Payment − Trade-In + Cap Cost Adders (acquisition fee, etc.) Residual Value = MSRP × Residual % Money Factor = Annual Interest Rate / 2,400 (so 6% APR = 0.0025 money factor) Example: $40,000 MSRP, $38,000 negotiated, $2,000 down, $0 trade-in, 55% residual, 0.002 money factor (4.8% APR equivalent), 36 months, 7% tax. Adjusted Cap Cost = $38,000 − $2,000 = $36,000 Residual Value = $40,000 × 0.55 = $22,000 Depreciation Fee = ($36,000 − $22,000) / 36 = $388.89/month Finance Fee = ($36,000 + $22,000) × 0.002 = $116.00/month Pre-tax payment = $504.89 Tax = $504.89 × 0.07 = $35.34 Total monthly payment = $540.23 Compare to financing the same $38,000: At 6% over 60 months: $735/month — much higher, but you own the car at end vs. returning it. At 6% over 36 months: $1,156/month — much higher but builds equity. Lease vs. buy economic comparison (long term, 36 months): Lease cost: $540 × 36 + $2,000 down = $21,440 + initial fees ($1,000-$2,000) = ~$22,500-$23,500 paid, no asset Finance cost (60 months at 6%, sold at month 36): Total paid by month 36: $735 × 36 + $5,000 down = $31,460 Estimated value at month 36: ~$22,000 (similar to residual) Remaining loan balance: ~$16,500 Net equity: $22,000 − $16,500 = $5,500 Net cost to month 36: $31,460 − $5,500 equity = $25,960 Lease is cheaper short-term (~$2,500 less) but leaves you with nothing. Buy is more expensive short-term but builds $5,500+ equity. Over 7-10 years of ownership (no more payments after loan paid off vs. another lease), buying is dramatically cheaper. Important fees often hidden: Acquisition fee: $500-$1,000 (lender charge to set up lease) Disposition fee: $300-$500 (charged at lease end unless buying out) Excess mileage charges: $0.15-$0.30 per mile over limit (often 10K-15K/year) Excess wear and tear: variable (often $200-$2K at lease end) Early termination penalty: substantial (often thousands) These add up: a 3-year lease may have $2K-$4K in fees beyond the monthly payment.

How to use this calculator

Get the MSRP (sticker price) and dealer-quoted negotiated price.
Enter cap cost reduction (down payment) — but consider whether putting money down is wise (see warnings below).
Enter trade-in value if applicable.
Look up residual value % for that vehicle/term combination — typically published in lease offers or available from leasing publications (e.g., RVI Group data). Higher residual = lower payment.
Look up the money factor for the offer — dealer should disclose, or you can ask "what's the money factor?" directly. Convert to APR by multiplying by 2,400 (so 0.002 = 4.8% APR equivalent).
Select lease term (36 months is most common; 24 and 39 also common).
Enter sales tax rate (varies by state — some states tax full purchase, some tax only the lease portion).
Review monthly payment breakdown.
Negotiate: cap cost (negotiated price) is most negotiable, money factor sometimes negotiable, residual value rarely negotiable (set by lender).
Verify the dealer's quoted payment matches your calculation. Discrepancies often reveal hidden fees or markups.

Worked examples

Standard 36-month lease

$40,000 MSRP Toyota RAV4, $38,000 negotiated, $0 down, 55% residual, 0.0015 money factor (3.6% APR), 36 months, 7% tax, 12K miles/year. Adjusted cap cost: $38,000 Residual: $22,000 Depreciation: ($38,000 − $22,000) / 36 = $444/month Finance fee: ($38,000 + $22,000) × 0.0015 = $90/month Pre-tax: $534. Tax: $37.38. Total: ~$571/month. Plus initial: ~$1,000 acquisition fee + first payment + DMV fees = $2,500-$3,000 due at signing. Total 3-year cost: $571 × 36 + $3,000 = $23,556. Vehicle returned at lease end (or buy out for $22K residual + sales tax).

Luxury lease with subsidized residual

$70,000 BMW 5-Series, $65,000 negotiated, $5,000 down, manufacturer-subsidized 62% residual (artificially high), 0.0008 money factor (1.9% APR — very low promotional rate), 36 months, 7% tax. Adjusted cap cost: $60,000 Residual: $43,400 (subsidized — actual market value at 3 years probably $32K-$36K) Depreciation: ($60,000 − $43,400) / 36 = $461/month Finance fee: ($60,000 + $43,400) × 0.0008 = $83/month Pre-tax: $544. Tax: $38. Total: ~$582/month. This is why luxury leases often look "cheap" compared to purchase — the manufacturer subsidizes through high residual and low money factor. Buying makes no sense (immediate $20K underwater); leasing is the financially correct choice for luxury cars driven 36 months and traded. Catch: buyout at lease end is unattractive because residual exceeds market value. Always return the vehicle, never buy out a luxury lease with subsidized residual.

Bad lease deal (high money factor)

$30,000 Honda Civic, $29,500 negotiated, $0 down, 48% residual (lower than fair), 0.0030 money factor (7.2% APR — bad), 36 months. Adjusted cap cost: $29,500 Residual: $14,400 Depreciation: ($29,500 − $14,400) / 36 = $419/month Finance fee: ($29,500 + $14,400) × 0.0030 = $132/month Pre-tax: $551. Tax: $39. Total: ~$590/month. Same car purchased at $29,500 with 6% financing over 60 months = $570/month — and at month 60, the buyer owns the car worth ~$14K. This is a bad lease. High money factor signals dealer or lender markup. Low residual signals an unfavorable vehicle to lease (Civics don't hold value as well as some competitors). Walk away or shop a different vehicle.

When to use this calculator

Use this calculator before signing any lease to verify quoted payments match the math, compare lease offers across vehicles, and assess whether each lease is competitive or contains hidden markups.

Pair with lease-vs-buy (head-to-head economic comparison) and car-affordability (general budgeting).

Important lease considerations:

1. **Negotiate the cap cost.** Many buyers don't realize the negotiated price is just as negotiable on a lease as on a purchase. Treat lease negotiation as purchase negotiation — get to a fair price first, then negotiate lease terms.

2. **Money factor is negotiable too.** Dealers can mark up the money factor (called "lease rate markup," similar to dealer reserve in financing). Always ask "what's the buy rate from the manufacturer captive lender?" Some captive lenders publish their rates publicly.

3. **Avoid large down payments on leases.** If the car is totaled or stolen, insurance pays the leasing company (not you) and your down payment is lost. Use down payments only to bring cap cost in line with vehicle value or to qualify for subvented rates. Otherwise, put nothing down beyond first-month payment.

4. **Watch the residual.** Subsidized residuals (artificially high) make leasing cheap and buying out at lease end unattractive. Low residuals (especially on traditionally low-residual vehicles) make leasing expensive. Compare residuals across competing vehicles in your category.

5. **Mileage limits matter.** Typical leases include 10K-15K miles/year. Excess miles are charged $0.15-$0.30 per mile at lease end. Driving 18K miles/year? You'll owe $2,500+ at lease end on a 36-month lease. Pay for higher mileage upfront ($0.10-$0.15/mile equivalent) if you know you'll exceed.

6. **Wear and tear standards are strict.** "Normal wear" is defined narrowly. Scratches, scuffs, interior wear, and minor dents can produce $500-$2,000 in end-of-lease charges. Consider lease-end inspection 60 days before return to address issues affordably.

7. **Early termination is brutal.** Breaking a lease typically requires paying remaining payments + early termination fee + difference between lease balance and vehicle value. Often $5,000-$15,000+ to exit early. Don't lease if uncertain about needing the vehicle for full term.

8. **Lease is most economical for short ownership.** If you actually plan to drive a vehicle 36-48 months and trade, leasing can be competitive with financing. If you plan to keep 5+ years, buying (especially used) is dramatically cheaper.

9. **GAP insurance matters.** Most leases include GAP coverage (covers difference between lease balance and insurance payout if vehicle is totaled). Verify it's included; if not, purchase separately.

10. **Disposition fee at end.** Most leases charge $300-$500 to return the vehicle at lease end. This fee is sometimes waived if you lease another vehicle from the same brand.

Common mistakes to avoid

Focusing only on monthly payment, not total lease cost. Dealers can hide markups in cap cost or money factor while showing attractive monthly numbers.
Putting large down payments on leases. If car is totaled or stolen, you lose the down payment. Lease minimum down.
Not negotiating the cap cost. The price is negotiable on leases exactly as on purchases. Get to fair price first.
Ignoring mileage and wear charges. End-of-lease excess mileage and wear-and-tear charges can total $2K-$4K. Estimate honestly upfront.
Leasing for too short a financial horizon. If you plan to keep a vehicle 5+ years, buying is dramatically cheaper than serial leasing.
Buying out a lease with subsidized residual. Luxury leases often have residuals above market value — always return, never buy out these leases.
