Buy vs. Lease Car Calculator

What Buy Versus Lease Really Compares

Buying builds ownership value but usually requires a larger payment or longer commitment. Leasing can lower the monthly payment but usually ends with no owned vehicle unless you buy it out.

The calculator compares cash paid during the period and adjusts for expected equity or resale value when buying. For leasing, it includes lease payments and upfront lease costs. For example, a $500 monthly lease can look cheaper than a $600 loan payment, but $2,000 due at signing and no owned equity at lease end can narrow or reverse the advantage.

The comparison is strongest when the time period matches. A three-year lease should be compared with three years of ownership costs and estimated equity, not the full life of the car. If you plan to keep a purchased car for six years, run a second scenario beyond the lease term because the buy side may improve after the loan is paid down.

Lease Costs To Include

Lease payment is only part of leasing cost. Include acquisition fees, disposition fees, upfront payments, taxes, registration, and any amount due at signing. A $399 advertised lease can be much closer to $470 per month once a $2,500 upfront amount is spread across a 36-month term.

Mileage limits matter. If you drive more than the lease allows, excess mileage charges can erase the monthly-payment advantage. At 20 cents per extra mile, driving 4,000 miles over the allowance adds $800 before any wear charges.

Wear-and-tear charges can also matter. Leasing works best when you can return the car within the contract's condition and mileage rules.

Buying Costs To Include

Buying cost includes loan payments, down payment, taxes, fees, maintenance after warranty, and the car's value at the comparison date. If three years of loan payments cost $21,600 but the car still has $6,000 of equity, the net cost is very different from looking at payments alone.

A financed car may have equity if its market value is higher than the remaining loan balance. It may have negative equity if depreciation outpaces repayment. This is also where gap insurance can matter: if a financed or leased car is totaled while the payoff is higher than the insurance value, gap coverage may help cover that shortfall depending on the policy and lease terms.

Longer ownership often favors buying because transaction costs are spread over more years and the car may be driven after the loan is paid off.

Mileage And Flexibility

High-mileage drivers often need to be careful with leases. Buying may be safer when mileage is unpredictable or consistently above lease limits. A driver who expects 18,000 miles per year should not compare a 10,000-mile lease against a purchase without pricing the extra miles first.

Leasing can fit drivers who want a newer car every few years, predictable warranty coverage, and lower repair exposure. Buying can fit better when you want to keep the vehicle after the loan, drive irregular mileage, or avoid lease return inspections.

Buying can fit drivers who keep cars longer, customize vehicles, drive irregular mileage, or want the option to sell whenever they choose.

Buy Or Lease Mistakes To Avoid

Do not compare lease payment with loan payment alone. That ignores equity, fees, mileage charges, taxes, possible gap coverage, and what happens at the end of the term. A lower lease payment can still lose if the purchase builds meaningful equity or if the lease has large upfront costs.

Do not make a large down payment on a lease without understanding the risk. If the car is totaled early, upfront money may not be recovered the way buyers expect. Ask whether gap coverage is included in the lease and how insurance proceeds are handled before putting a large amount due at signing.

Do not overestimate resale value. A rosy resale assumption can make buying look better than it will be in the market.

Buy Vs. Lease Scenarios To Run

Run the comparison at the exact lease term first, such as 36 months. Then test a longer ownership period to see whether buying improves after the lease would have ended. For example, buying may look worse at 36 months but better at 60 months if the payment ends and resale value remains meaningful.

Run a high-mileage lease scenario if your driving varies. Add estimated excess mileage charges before choosing the lease. Also run a tax-and-fee scenario because some states tax leases and purchases differently, and business-use deductions can differ between buying and leasing.

Run a lower-resale scenario for buying. If buying only wins with a strong resale value, the decision depends heavily on the future used-car market.
