Buying is usually cheaper over the full life of the car, because you eventually own an asset and stop making payments. Leasing is usually cheaper month to month and over very short horizons, because you only pay for the depreciation during the term instead of the whole vehicle. The crossover typically arrives somewhere between years four and six of ownership. This calculator finds the crossover for your actual numbers rather than an average.
Add up every dollar that leaves your account over the same period, then subtract what you still own at the end. For buying: down payment, trade-in, all loan payments made, insurance, maintenance, plus any loan balance still outstanding, minus the car’s resale value. For leasing: due at signing, every lease payment, acquisition and disposition fees, sales tax, insurance, maintenance, and excess-mileage charges — with nothing subtracted at the end, because you own nothing. The lower total is the cheaper option.
A down payment lowers the amount financed and therefore the interest you pay, but it is still your cash and still counts in the total. It changes the monthly payment far more than it changes the true cost. Putting a large amount down on a lease is riskier still: if the car is totalled or stolen early, that money is generally not returned to you.
Residual value is the amount the leasing company predicts the car will be worth when the lease ends, usually written as a percentage of MSRP. A 52% residual on a $45,000 car means they expect it to be worth about $23,400 at turn-in. You pay for the difference between the capitalized cost and the residual, so a higher residual means a lower monthly payment. It is the single most powerful number in a lease quote.
The money factor is the lease equivalent of an interest rate, quoted as a small decimal such as 0.0021. Multiply it by 2,400 to get the approximate APR: 0.0021 × 2,400 = 5.04% APR. Comparing the converted APR against the loan APR you were offered tells you whether the lease financing is actually competitive.
A typical new car loses roughly 20% of its value in the first year and about 15% of its remaining value in each following year, leaving it worth around 40–55% of its purchase price after five years. Depreciation is the largest single cost of owning a new car — usually larger than fuel, insurance, interest, or maintenance — even though no bill ever arrives for it.
Use both, in their proper places. MSRP is the reference point lease residuals are quoted from, so enter it as the sticker price. The negotiated price is what actually drives your cost, so enter the number you can genuinely get — it determines the loan amount when buying and the capitalized cost when leasing. Negotiating the price down helps a lease just as much as it helps a purchase, which many shoppers do not realise.
Enter your honest annual mileage, not the lease allowance. The US average is about 13,500 miles per year, while standard leases allow 10,000 or 12,000. If you drive more than the allowance, the calculator charges the overage at your excess-mileage rate — typically $0.15 to $0.30 per mile — which is where leases quietly become expensive for high-mileage drivers.
Generally no. Excess-mileage charges are the most common way a cheap-looking lease turns expensive. At $0.25 per mile, driving 18,000 miles a year on a 12,000-mile allowance costs $1,500 per year, or $4,500 over a three-year lease. High-mileage drivers usually do better buying, where extra miles reduce resale value but are never billed directly.
You return the car, pay a disposition fee of typically $350 to $500, and settle any charges for excess mileage or wear beyond the contract’s definition of normal. You then have no vehicle and no equity. Alternatively you can buy the car for the residual value stated in your contract, which is worth doing only when the residual is below the car’s real market value.
Yes. The monthly cost divides the estimated total cost by the number of months being compared, and that total includes insurance, maintenance, taxes, fees, financing, and — on the buy side — the resale value you get back. It is deliberately higher than a payment quote, because a payment quote is not what the car costs you.
