A car lease vs buy calculator helps you see the true total cost of each financing option over the same ownership period — not just the monthly payment. Leasing often has a lower sticker payment, but buying builds equity and can be cheaper long-term. Enter your numbers below to find out which option wins for your situation.

How to Use the Car Lease vs Buy Calculator
Deciding whether to lease or buy a car is one of the biggest financial decisions most people make regularly. The monthly payment is the most visible number, but it tells only part of the story. A lease with a $300 monthly payment can cost more in total than a purchase with a $450 monthly payment, depending on how long you keep the vehicle and what it is worth when you stop using it. This car lease vs buy calculator computes the complete picture over your expected ownership period, so you can compare real total costs — not just monthly obligations.
Step 1: Enter Your Buying Scenario
Start with the vehicle price (the amount you will pay or finance, after any negotiation). Enter your planned down payment, the loan interest rate (APR) your lender is offering, and the loan term in months. Then set how many years you plan to own the car and your expected annual mileage. The calculator uses mileage to estimate depreciation and resale value — cars driven fewer miles per year hold their value better.
Step 2: Enter Your Leasing Scenario
Enter the monthly lease payment quoted by the dealer. Add any upfront cost (cap cost reduction or lease down payment). Set the lease term (most leases run 24, 36, or 48 months). The residual value percentage is the estimated worth of the car at lease end as a percentage of the original vehicle price — your dealer will provide this number. Finally, set the mileage allowance included in the lease and the per-mile fee for going over that limit.
Step 3: Understand the Results
The calculator projects costs over your full ownership period. For buying, this means all loan payments plus estimated insurance and maintenance, minus the car's resale value when you sell or trade it. For leasing, it means all lease payments across sequential lease cycles (if your ownership period is longer than one lease term), plus typical acquisition and disposition fees, plus any excess mileage charges based on the gap between your expected annual mileage and the lease allowance. The result is a side-by-side table with a clear total for each option.
Break-Even Point
The break-even point is the number of years at which cumulative buy costs equal cumulative lease costs. If you plan to keep the car beyond the break-even point, buying becomes more economical. If you prefer switching vehicles frequently or value the simplicity of a fixed-term commitment, leasing may be a better lifestyle fit even if buying is mathematically cheaper. The calculator shows you exactly where that crossover happens so you can make the decision on your own terms.
Tips for a Better Comparison
Get real quotes from lenders and dealers before entering numbers — the difference between a 5% and 7% loan rate can shift the result significantly. For residual value, check Kelley Blue Book or Edmunds estimates for your specific model and mileage, or ask the dealer to show you the residual percentage written into the lease contract. Remember that leasing always means returning the car, so factor in whether you would be happy repeating the process every 2–4 years. Buying is usually better for high-mileage drivers and people who prefer to own their assets outright.
Frequently Asked Questions
Is it better to lease or buy a car?
It depends on your situation. Leasing usually offers lower monthly payments and the ability to drive a new car every few years, but you build no equity and face mileage limits. Buying costs more upfront but the car becomes yours — an asset you can sell or keep. This calculator shows you the true total cost over your ownership period so you can make an informed decision.
What costs does the lease vs buy calculator include?
For buying: total loan payments (principal + interest), plus estimated insurance and maintenance costs, minus the projected resale value at the end of your ownership period. For leasing: all lease payments over the lease term, acquisition and disposition fees, and an excess mileage risk buffer if your expected annual mileage exceeds typical limits. This gives you a realistic apples-to-apples comparison.
What is a residual value in a car lease?
The residual value is the estimated worth of the car at the end of the lease term, expressed as a percentage of the original MSRP. For example, a 55% residual on a $30,000 car means the dealer expects the car to be worth $16,500 after 36 months. A higher residual value generally means lower monthly lease payments, because you are financing a smaller portion of the car's depreciation.
How is the break-even point calculated?
The break-even point is the number of years at which the cumulative cost of buying equals the cumulative cost of leasing. Before that point, leasing is cheaper in total; after it, buying becomes the more economical choice. If you plan to keep the car beyond the break-even point, buying is typically better. If you prefer shorter commitments or plan to switch cars sooner, leasing may win.
Does this calculator account for sales tax?
The calculator focuses on the core financial comparison — loan payments, lease payments, and residual value — without applying a specific tax rate, since sales tax varies widely by state and country and can apply differently to leases vs purchases. For a precise local comparison, add your estimated sales tax to the inputs or consult your dealer for a full out-the-door cost breakdown.
