Leasing and buying each have real financial tradeoffs. This calculator breaks down every monthly cost so you can make the right choice for your situation.
Understanding the Core Cost Difference
The lease-versus-buy decision hinges on one fundamental question: Do you want to own an asset or pay for temporary use? These aren’t just different financing options—they’re entirely different relationships with a vehicle.
When you buy a car, you’re making a long-term investment. You pay a down payment, take out a loan (or pay cash), and own the vehicle outright once the loan is paid off. You’re responsible for all maintenance, repairs, insurance, registration, and taxes. But after the loan ends, you have a paid-off asset that can be driven for years with only routine maintenance costs.
When you lease a car, you’re essentially renting it for 2–4 years. You make monthly payments to use the vehicle, but you never own it. The manufacturer covers most major repairs and maintenance through the warranty. You pay a capitalized cost (similar to a down payment), monthly payments, insurance, and a disposition fee at the end. Mileage limits apply—usually 10,000–15,000 miles per year—and excessive wear charges can add up.
The right choice depends on your driving habits, how long you keep cars, and whether predictable payments matter more to you than long-term ownership costs.
Building Your Month-by-Month Cost Spreadsheet
To compare leasing and buying fairly, you need to track every cost for 36, 48, or 60 months—the typical lease term or loan length. Don’t just look at monthly payments; missing other costs is where most people get blindsided.
For buying, include: Down payment (spread across the loan term), monthly loan payment, comprehensive and collision insurance, property tax (varies by state), registration and renewal fees, maintenance (oil changes, brakes, tires), and repairs. Create a separate row for each month, because maintenance and repair costs aren’t evenly distributed. Major repairs often hit years 3–5, so your true monthly average can be misleading if you only look at year one.
For leasing, include: Down payment (capitalized cost reduction), monthly lease payment, comprehensive and collision insurance, registration (usually included in the lease but verify), and the disposition fee at lease end (typically $300–$500). Maintenance is covered, but track it as $0 to make the comparison clean. Many leases bundle registration, so read the contract carefully. Also factor in overage charges for mileage beyond your allowance—calculate this as excess mileage multiplied by the lease’s per-mile charge (usually $0.25–$0.30).
Use a simple spreadsheet: columns for month, purchase costs, lease costs, and running total. After 36 or 48 months, divide the total by the number of months to get your true average monthly cost. That’s your apples-to-apples comparison number.
Key Variables That Shift the Equation
Annual mileage is the single biggest wildcard. If you drive 5,000 miles per year, leasing often wins—you’ll stay well under lease limits and avoid the depreciation hit that high-mileage cars take. If you drive 20,000 miles per year, leasing becomes expensive fast. At $0.25 per excess mile, you’ll pay $1,500 per year over a 15,000-mile limit. Buying suddenly looks much smarter.
Vehicle choice matters too. Luxury cars and new models with advanced technology often favor leasing. A $60,000 luxury sedan depreciates 50–60% over five years; a lease caps your exposure at monthly payments plus overage fees. By contrast, a Toyota Corolla or Honda Civic holds value better, making purchase more attractive financially. Calculate depreciation as: (purchase price − projected resale value) ÷ months. For a $25,000 car worth $15,000 after 60 months, that’s $167 per month in depreciation—cheap compared to many lease payments.
Insurance rates vary dramatically by car, age, and region. A new luxury sedan might cost $150–$200 per month to insure, while a 3-year-old practical sedan could be $80–$120. Call your insurer for quotes on both the leased and purchased vehicles you’re considering—don’t guess. This can swing the decision by hundreds of dollars annually.
Maintenance costs escalate with age. Year one might cost $200 (oil changes, air filters). By year five, major repairs like transmission issues, suspension work, or engine problems can hit $2,000–$5,000 in a single month. Leases avoid this entirely because the vehicle is under warranty. If you’re risk-averse and want predictable costs, that peace of mind has real value.
Real Numbers: Three Scenarios
Scenario 1: The Low-Mileage City Driver You drive 6,000 miles per year, mostly short trips, and prefer always having a new car with no surprises. You’re eyeing a $32,000 midsize sedan with a lease at $350/month (36 months). Down payment: $3,000. Insurance: $110/month. Registration included. Total: $3,000 + (36 × $460) = $19,560 over three years, or $544/month.
If you bought that same car: $5,000 down, $550/month loan, $130/month insurance, $100/month maintenance (average), $50/month registration and taxes. Total: $5,000 + (36 × $830) = $34,880 over three years, or $969/month. Add $10,000 in depreciation (conservative for a well-maintained car), and you’re around $45,000 total. Leasing saves you roughly $25,000 over three years in this scenario.
Scenario 2: The High-Mileage Commuter You drive 18,000 miles per year, need something reliable, and plan to keep it 7 years. That $32,000 sedan as a lease: $3,000 down, $350/month payment, but you’re 3,000 miles over annually = $900/year × 7 years = $6,300 in overage charges. Plus insurance, fees. Total: roughly $3,000 + (84 × $460) + $6,300 = $43,440. If you leased a different car or shopped for better overage terms, you might reduce this slightly, but high mileage crushes lease economics.
Buying: $5,000 down, $550/month loan, $130/month insurance, $150/month maintenance (higher for heavy use), $60/month registration/taxes. Over 84 months: $5,000 + (84 × $890) = $79,760. After 7 years, sell for ~$8,000–$12,000 (high-mileage cars depreciate more). Net cost: ~$68,000–$72,000, or $810/month. Buying is modestly cheaper here, and you own an asset at the end.
Scenario 3: The Practical Budget Buyer You want the cheapest total cost over 5 years. You buy a $18,000 used 3-year-old Toyota Corolla outright with cash. Insurance: $85/month. Maintenance: $75/month (used cars need more attention but are simpler to repair). Registration/taxes: $40/month. Over 60 months: $0 down + (60 × $200) = $12,000 in operating costs. Sell it for $8,000–$10,000. Net: $2,000–$4,000, or $33–$67/month. Leasing can’t compete financially in this scenario.
How to Use the Numbers to Decide
Calculate your true monthly cost for both options using actual quotes, not averages. Plug in your expected annual mileage, local insurance rates, and anticipated maintenance or overage charges. Whichever number is lower over your planned ownership or lease term is the financially superior choice.
But money isn’t everything. If predictable payments and zero repair risk are worth thousands of dollars to you, leasing is rational even if buying is slightly cheaper. If you love driving new cars and don’t want depreciation exposure, lease. If you drive a lot, keep cars long-term, or want to eventually own something free and clear, buying usually wins mathematically—and you’ll sleep better knowing the car is yours.
Get real quotes from dealers and lenders, build your spreadsheet, and compare the total costs. The answer will be clear.
