Car Lease Calculator

Leasing a $40,000 car you negotiate down to $37,000, with a 57% residual, a 0.0025 money factor, $2,000 down and 7% tax on a 36-month term, works out to about $517 per month. Of that, roughly $339 is depreciation, $145 is the finance (rent) charge, and $34 is sales tax. Over the full lease you would pay about $18,620 in payments, or $20,620 once you count the down payment. This car lease calculator breaks every dollar into those parts so you can see exactly what you are paying for - and where you can negotiate.

How a lease payment is calculated

Unlike a loan, a lease only charges you for the portion of the car you actually use - the depreciation - plus rent on the money. The monthly payment is the sum of three pieces:

where:

The finance charge surprises people because it is based on the cap cost plus the residual, not just the amount you are using. That is because you are paying rent on the full value of the car the bank is holding for you. The money factor is just interest in disguise: multiply it by 2,400 to get the APR, so 0.0025 is a 6% APR.

A worked example, step by step

Using the default numbers above:

• Residual = $40,000 × 57% = $22,800.
• Adjusted cap cost = $37,000 − $2,000 down − $0 trade = $35,000.
• Depreciation = ($35,000 − $22,800) ÷ 36 = $338.89/mo.
• Finance charge = ($35,000 + $22,800) × 0.0025 = $144.50/mo.
• Base payment = $338.89 + $144.50 = $483.39/mo.
• Sales tax = $483.39 × 7% = $33.84/mo, for a total of $517.23/mo.

That is the entire math behind your lease. Every figure the dealer quotes you traces back to one of these inputs, which is exactly why knowing them gives you leverage.

How to use this car lease calculator

You only need the numbers from a lease worksheet to get a realistic estimate. Work through the fields in order:

1. MSRP: the sticker price. The residual percentage is applied to this number, so use the full window-sticker MSRP, not the discounted price.
2. Negotiated price: the selling price you agree to (also called the gross cap cost). This is the most negotiable input.
3. Residual value (%): the bank's predicted end-of-lease value as a percent of MSRP. Ask the dealer or check the manufacturer's lease program.
4. Money factor: the lease interest rate. The calculator shows the equivalent APR next to it (money factor × 2,400).
5. Lease term: 24, 36, 39 or 48 months. 36 months is the most common.
6. Down payment & trade-in: any cap-cost reduction lowers the adjusted cap cost, and therefore both depreciation and the finance charge.
7. Sales tax (%): your state or local rate. The calculator taxes the monthly payment, the most common US method.

Press Calculate and read the monthly payment at the top, then scroll the breakdown to see depreciation, finance charge and tax both per month and across the whole term.

Who this calculator is for

• Shoppers comparing lease deals who want to check a dealer's quoted payment against the underlying math.
• Negotiators testing how much a lower price, a base money factor, or a stronger residual would save each month.
• Lease-vs-buy deciders who want a clean monthly number to set against an Auto Loan Calculator estimate.
• Budgeters who need the true monthly cost - including tax - before they sign.
• Anyone handed a confusing lease worksheet full of unfamiliar terms like cap cost, residual and money factor.

Key lease terms explained

• Capitalized (cap) cost: the price being financed in the lease - basically the negotiated vehicle price.
• Cap-cost reduction: anything that lowers the cap cost up front - your down payment, trade-in equity or a rebate.
• Adjusted (net) cap cost: the cap cost after those reductions; the number the payment is actually built on.
• Residual value: the predicted end-of-lease value, set by the bank as a percent of MSRP. Higher is better for you.
• Money factor: the lease interest rate; multiply by 2,400 for the APR.
• Depreciation: the value the car loses while you drive it - the biggest part of most payments.
• Buyout / purchase option: the price to buy the car at lease end, usually the residual plus a fee.

Scenario A: lease with zero down

Take a $35,000 car negotiated to $33,000, a 55% residual, a lower 0.0020 money factor (about a 4.8% APR), 36 months, nothing down and 6% tax. The residual is $19,250 and, with no cap-cost reduction, the adjusted cap cost stays at $33,000. Depreciation is about $381.94/mo, the finance charge about $104.50/mo, and after tax the payment lands near $515.63/mo - roughly $18,563 over the full term with no cash up front. This shows how a stronger residual and a lower money factor can offset a higher selling price.

Scenario B: a pricier car with money down

Now a $50,000 vehicle negotiated to $47,000, a 60% residual, a 0.0030 money factor (about a 7.2% APR), 36 months, $3,000 down and 8% tax. The residual is $30,000 and the adjusted cap cost drops to $44,000. Depreciation is about $388.89/mo, the finance charge about $222/mo, and the after-tax payment is roughly $659.76/mo. Counting the $3,000 down, the total lease cost is around $26,751. The high money factor alone adds nearly $8,000 in rent over three years - which is why shaving the money factor matters as much as the price.

What changes the lease payment the most

If you adjust the inputs and watch the payment move, a few levers dominate:

• Negotiated price: the most controllable lever - it lowers both depreciation and the finance charge.
• Residual value: a higher residual means less depreciation; even a few points changes the payment a lot.
• Money factor: directly sets the finance charge; ask for the bank's base rate, not a marked-up one.
• Term length: a longer lease spreads depreciation over more months but adds finance charges.
• Down payment & trade-in: lower the monthly payment but tie up cash you can lose if the car is totaled early.
• Sales tax rate: small per month but compounds across the term and varies widely by state.

Tips to get a lower lease payment

• Negotiate the cap cost first, before mentioning that you want to lease - treat it like a cash purchase.
• Ask for the base money factor; dealers can mark it up, and a 0.0005 difference is real money over three years.
• Choose a car with a high residual - models that hold value lease cheaply even when their price is high.
• Put little or nothing down and pay slightly more per month rather than risk losing a large up-front sum.
• Match the mileage allowance to how you drive; do not overpay for miles you will not use.
• Stack manufacturer lease incentives, which act as cap-cost reductions or subsidized money factors.

Lease vs. buy, in one paragraph

A lease almost always has a lower monthly payment than financing the same car, because you only pay for the depreciation during your term rather than the whole vehicle. The trade-off is that you build no equity, you face mileage limits and end-of-lease fees, and you start over when the lease ends. Buying costs more each month but the car is yours - and once a loan is paid off you can drive for years with no payment. If your priority is the lowest payment and always having a newer car, leasing wins; if it is the lowest total cost over many years, buying and keeping the car usually wins. Run both with our Auto Loan Calculator and Car Payment Calculator before deciding.

Limitations and assumptions

This calculator is a planning estimate, not a lease quote. Keep these in mind:

• It taxes the monthly payment, which is the most common US method, but some states tax the full price or the down payment up front.
• It excludes acquisition (bank) fees, disposition fees, registration and the first payment typically due at signing.
• It does not model excess-mileage or wear-and-tear charges, which are settled when you return the car.
• It shows the payment during the lease, not the residual buyout if you choose to purchase the car at the end.
• Your actual money factor and residual depend on the lender, your credit and the specific program - confirm them on the dealer's worksheet.

How it compares to related calculators

This page answers "what is my monthly lease payment?" If your question is different, a sister tool fits better:

• To finance a car you intend to own, use the Auto Loan Calculator or the Car Payment Calculator.
• For any fixed-rate borrowing, use the general Loan Calculator.
• To compare unsecured borrowing, use the Personal Loan Calculator.
• To plan paying down balances, use the Credit Card Payoff or Debt Payoff calculators.

Lease vs. finance: a side-by-side cost comparison

The fairest way to judge a lease is to price the exact same car as a loan and compare the cash that leaves your account. Take the $37,000 negotiated car from the default example. Lease it for 36 months at a 0.0025 money factor with $2,000 down and you pay about $517/month, or roughly $20,620 in cash over three years - but at the end you own nothing and hand the keys back. Finance the same $35,000 (after the same $2,000 down) over 60 months at a 6.5% APR on our Auto Loan Calculator and the payment is about $685/month. That loan looks more expensive month to month, but after 36 months you have paid down a large slice of the balance and you keep an asset worth roughly the residual ($22,800) when the lease would have ended.

That equity is the crux of the decision. With a lease, every dollar is consumed - you rent the depreciation and walk away. With a loan, part of each payment buys ownership you can later sell, trade, or drive payment-free once the note is retired. The break-even depends on how long you keep the car: drivers who swap vehicles every two to three years usually come out ahead leasing because they never reach the payment-free years, while drivers who keep a car for 8-10 years almost always pay less by buying. Mileage habits matter too - a heavy commuter who would blow past a 12,000-mile lease allowance and rack up overage fees is often better off owning, where miles only affect resale value, not a per-mile penalty. Run the same vehicle through both this page and the Car Payment Calculator before you commit; the right answer is the one that fits your time horizon and driving, not the lowest sticker payment.

Reading a dealer lease worksheet

When a dealer hands you a lease worksheet, the numbers on it map directly onto this calculator's inputs - they are just labelled in industry shorthand. The gross capitalized cost is your negotiated price; the capitalized cost reduction lumps together your down payment, trade-in equity and any rebates; subtract one from the other and you have the adjusted (net) capitalized cost the payment is built on. The residual may be shown as a dollar figure rather than a percent - divide it by the MSRP to recover the percentage this tool uses. The money factor is sometimes hidden or quoted as a "lease rate"; if you only see an APR, divide it by 2,400 to get the money factor, and if you only see a money factor, multiply by 2,400 to sanity-check the rate. Watch for a money factor that has been marked up above the bank's buy rate, and for fees - the acquisition (bank) fee and disposition fee - quietly rolled into the cap cost, because rolling a fee into the cap cost means you also pay rent charge on it. If a worksheet's monthly payment does not match what this calculator shows for the same inputs, the gap is almost always one of those buried fees or a marked-up money factor, which is exactly the kind of thing worth questioning before you sign.
