Does this include resale value?

No. The calculator focuses on cash outlay: down payment, fees, and monthly payments. To compare lifetime ownership costs, estimate a conservative resale value for the car at the end of your planned ownership period and subtract it from the buy total.

Yes. Fold sales tax and registration into the appropriate inputs based on how your region charges them. For example, if tax is applied to the vehicle price when buying, add it to the vehicle price or treat it as part of the down payment; if tax is applied to lease payments, increase the lease payment or include tax amounts in the lease fees.

Does this account for mileage limits and wear‑and‑tear fees on leases?

Not automatically. If you expect to pay mileage or wear fees at the end of the lease, add an estimate of those charges into the lease fees field so they are reflected in the total lease cost.

Which option is better for my credit score or future financing?

The calculator does not model credit score impacts or lender underwriting policies. Both leases and loans appear on your credit, and payment history, debt‑to‑income, and utilization all matter. Use this tool for cost comparisons and talk to a lender or advisor about credit implications.

Can I use this for used cars or certified pre‑owned deals?

Yes. As long as you have a vehicle price and loan or lease terms, you can plug them into the calculator. Just remember that used‑car leases and loans may have different residual values, maintenance expectations, and warranty coverage than new‑car deals, which are not modeled here.

Overview

Deciding whether to lease or buy a car is one of the biggest money questions in everyday personal finance. Lease ads emphasize low monthly payments and always driving something new, while finance offers focus on long‑term ownership and building equity. This lease vs buy car calculator pulls both deals onto the same footing so you can compare the monthly payment for a purchase against the total cost of a lease over its term.

It focuses on the cash you actually write checks for: down payment, fees, and monthly payments on each option. By entering the vehicle price, down payment, APR, and loan term for a purchase alongside the lease payment, term, and upfront due amounts, you can see which path keeps your monthly obligation lower and which one requires less total cash over the comparison window.

You can treat the results as a starting point for deeper analysis. If you tend to keep cars for a long time, you might layer in estimates of resale value or a post‑lease buyout; if you prefer always driving a newer vehicle, you might focus more on monthly affordability and the flexibility of rolling into another lease at the end of the term.

How to use this calculator

Gather the details for the purchase option: negotiated vehicle price, the cash you plan to put down, the offered APR, and the loan term in months.
Gather the details for the lease offer: monthly lease payment, lease term in months, cash due at signing, and any acquisition or disposition fees you expect to pay.
Enter the vehicle price, loan down payment, APR, and loan term into the buy side of the calculator.
Enter the lease monthly payment, lease term, due at signing, and fees into the lease side.
Review the buy monthly payment, total cost to buy, total lease cost, and the cost difference to see which path is cheaper over the comparison period and which offers a more comfortable monthly payment.
Adjust down payment, term length, APR, or lease terms to explore scenarios like longer loans, higher down payments, different lease specials, or zero‑down offers and see how the trade‑offs change.

Inputs explained

Vehicle price: The sticker or negotiated purchase price of the car before down payment. This is the starting point for the loan calculation; your down payment reduces how much of this price you actually finance.
Loan down payment: The cash you plan to put down when buying the car. The calculator subtracts this from the vehicle price to determine the financed amount for the loan.
Loan APR: The annual percentage rate on the auto loan if you buy. The calculator converts this into a monthly interest rate (APR ÷ 12) to compute the payment schedule.
Loan term (months): The length of the loan in months (for example, 36, 48, 60, or 72). Longer terms reduce the monthly payment but generally increase total interest paid.
Lease monthly payment: The advertised or quoted monthly payment for the lease. This payment is multiplied by the lease term and combined with due‑at‑signing cash and fees to find total lease cost.
Lease due at signing: The cash due when you sign the lease, such as first payment, down payment (cap cost reduction), and other required upfront amounts. Enter the total you expect to pay at signing.
Lease fees (acq/disposition): Any additional lease charges such as acquisition fees, disposition fees at the end of the lease, documentation fees, or other non‑monthly charges you expect to pay. You can combine them into a single estimated figure.
Lease term (months): The length of the lease in months (for example, 24, 36, or 39). The calculator multiplies the monthly lease payment by this term to compute the payment portion of total lease cost.

Outputs explained

Buy monthly payment: The estimated fixed monthly loan payment required to pay off the financed amount (vehicle price minus down payment) over the loan term at the specified APR.
Total cost to buy: Your total cash outlay for the purchase over the loan term, calculated as loan down payment plus monthly payment × loan term. This does not subtract any future resale value.
Total lease cost: Your total cash outlay for the lease over the lease term: lease due at signing + lease fees + monthly lease payment × lease term.
Lease − Buy cost: The difference between lease total cost and buy total cost. A positive number means leasing is more expensive than buying over the modeled period; a negative number means leasing is cheaper than buying for the same horizon.

How it works

The calculator first models the buy side as a standard auto loan. It subtracts your loan down payment from the vehicle price to determine the financed amount (principal) and converts the APR into a monthly interest rate by dividing by 12.

Using that monthly rate and the loan term in months, it applies the standard amortization formula to compute a fixed monthly payment that would fully pay off the principal and interest over the term.

Total buy cost over the term is then calculated as your loan down payment plus the monthly payment multiplied by the number of loan months. This represents the cash you will have paid to own the car outright at the end of the loan, before considering resale value.

On the lease side, the calculator adds your lease due at signing (cash you pay up front), any additional lease fees (such as acquisition or disposition fees), and the stream of lease monthly payments over the lease term to compute total lease cost.

Both totals are calculated over their own time frames: the buy total assumes you carry the loan to the end of its term, and the lease total assumes you complete the full lease term with the stated payment and fees.

The cost difference output is defined as Lease total cost − Buy total cost. A positive number means leasing costs more cash than buying over the modeled window; a negative number means leasing is cheaper than buying for the same comparison period.

Formula

Let:\n• P = vehicle price\n• d = loan down payment\n• APR = annual percentage rate for the loan (decimal)\n• r = APR ÷ 12 = monthly interest rate\n• n = loan term in months\n• Lp = lease monthly payment\n• Ld = lease due at signing\n• Lf = lease fees (acq/disposition, etc.)\n• Ln = lease term in months\n\nLoan principal = max(P − d, 0)\nIf r = 0: Buy payment = Principal ÷ n\nElse: Buy payment = Principal × [r × (1 + r)^n] ÷ [(1 + r)^n − 1]\n\nBuy total cost = d + (Buy payment × n)\nLease total cost = Ld + Lf + (Lp × Ln)\nCost difference (Lease − Buy) = Lease total cost − Buy total cost

When to use it

Comparing a dealer lease special against a standard financing offer from your bank or credit union to see which requires less total cash over the next few years.
Estimating cash needs upfront versus over time—for example, a low‑down‑payment lease with higher monthly payments versus a larger down payment and lower loan payment.
Running scenarios with higher or lower down payments to see when buying starts to beat leasing on both total cost and monthly payment.
Evaluating whether to lease an EV with manufacturer subsidies versus buying the same vehicle with available tax credits and standard financing.
Helping a friend, partner, or client visualize the trade‑offs between being payment‑focused (monthly amount) and cost‑focused (total outlay) when choosing between lease and buy.

Tips & cautions

Include taxes and registration where they apply. Some regions tax monthly payments while others tax the vehicle price or upfront costs—fold those amounts into the relevant inputs so the comparison reflects your real costs.
If you plan to keep the car long‑term, consider estimating a conservative resale value at the end of your ownership window and subtracting it from the buy total to approximate net ownership cost.
Remember that leases often have mileage limits and wear‑and‑tear fees. Heavy drivers or people who are hard on vehicles may find that these extra charges tilt the math toward buying.
Try multiple time horizons. A 36‑month lease compared to a 60‑month loan is not a perfect apples‑to‑apples comparison; think about how long you actually want to drive this car and whether you would sell or refinance sooner.
Don’t forget non‑financial factors: warranty coverage, how often you like having new technology or safety features, and your tolerance for future repair risk can matter just as much as the pure cost numbers.
Does not include insurance differences, maintenance, repair costs, or fuel costs, all of which can vary between vehicles and ownership patterns.
Assumes a fixed APR and fixed lease payment for the full term; it does not model variable APRs, changes in lease terms, or mid‑term renegotiations.
Does not automatically incorporate mileage penalties, excess wear charges, or disposition fees beyond what you manually include in the lease fees input.
Resale value and post‑lease buyout options are not modeled directly. To approximate lifetime ownership costs, you must estimate and subtract a resale or residual value yourself.
Treats both scenarios over their native terms; it does not automatically align them to a longer multi‑cycle horizon (for example, several back‑to‑back leases versus buying and keeping a car for 10+ years).

Worked examples

Example 1: $40k SUV vs promo lease

You’re considering a $40,000 SUV. The buy offer is $4,000 down, 5.25% APR, and a 60‑month term.
The lease offer is $3,000 due at signing, $1,000 in fees, and $489 per month for 36 months.
Enter these numbers into the calculator. The buy side shows a higher monthly payment but also a higher total cost over 60 months.
The lease side shows a lower total cost over 36 months, but you will not own the vehicle at the end of the lease and may need another car decision sooner.

Example 2: Entry EV purchase vs subsidized lease

An entry‑level EV can be financed at 4.5% APR for 72 months with modest rebates, or leased for 36 months with a heavily subsidized payment.
Plug in the EV’s price, down payment, APR, and 72‑month loan term on the buy side, and the lower lease payment, term, due at signing, and fees on the lease side.
The calculator reveals whether lease incentives are strong enough to make the lease cheaper than buying over the initial three‑year horizon, even before considering long‑term resale value.

Example 3: Testing higher down payments

Start with a baseline scenario where you put 10% down and compare lease vs buy.
Increase the loan down payment to 20% and rerun the calculator.
You’ll see the buy monthly payment drop and total buy cost change, which may shift the balance between lease and buy depending on how much cash you are comfortable tying up up front.

Deep dive

Use this lease vs buy car calculator to compare leasing versus financing the same vehicle by entering vehicle price, down payment, APR, and loan term alongside lease payment, term, due at signing, and fees. See your buy monthly payment, total cost to buy, total lease cost, and the cost difference in dollars.

It’s ideal for car shoppers weighing dealer lease promotions against finance offers without building a spreadsheet. Run quick what‑if scenarios, layer in your own assumptions about resale value, and use the results to have more informed conversations with dealers and lenders.
