How to choose between leasing and buying a car using total cost of ownership
Deciding whether to lease or buy a car comes down to money, miles, and personal preferences. This guide walks you through a clear total cost of ownership approach so you can compare the real numbers over the period you plan to drive the vehicle.
Step 1: Define your time horizon
Choose a clear comparison period, such as 3, 4, or 5 years. Leasing contracts often run 24–48 months, while loans commonly last 36–72 months; pick the span that matches how long you expect to keep the vehicle to ensure apples-to-apples costs.

Step 2: Estimate purchase costs
If buying, list the purchase price, sales tax, registration fees, and any optional add-ons. Use the out-the-door price; for example, a $30,000 sticker price might become $31,800 with 6% tax and $600 in fees.

Step 3: Estimate lease costs
For a lease, note the capitalized cost, down payment, acquisition fee, monthly payment, and disposition fee. Multiply monthly payment by the lease term and add upfront and end charges; a $300/month lease for 36 months plus $2,000 down equals $12,800 total payments.

Step 4: Calculate financing expense
When buying with a loan, calculate total finance charges using the interest rate and loan term. For example, a $28,000 loan at 4% APR for 60 months yields about $2,400 in interest; include that in your ownership cost.

Step 5: Project depreciation and resale
Estimate how much value the car will lose over your time horizon and your expected resale or trade-in value. Use a typical depreciation rate of 15–25% year one then 10–15% later; for a $30,000 car, expect roughly $18,000–$22,500 resale after three years.

Step 6: Add operating and fixed costs
Estimate fuel, maintenance, insurance, and registration over the period. Use concrete numbers like 12,000 miles/year, 30 mpg, $3.50/gallon, and $800/year insurance to calculate totals; include scheduled maintenance and expected repairs (e.g., $500/year).

Step 7: Compare total cost of ownership
Sum all buying costs (purchase, finance, operating) and subtract resale value to get net cost. For leasing, sum lease payments, fees, fuel, insurance, and any excess mileage or damage charges. Compare annualized cost (total divided by years) and consider flexibility, mileage, and tax differences.

- Include opportunity cost of down payment; assume 2–5% annual return if invested.
- If you drive over lease limits, add $0.10–$0.35 per mile for excess mileage to your lease cost.
- Check manufacturer warranty coverage: leased cars often remain under warranty for full term, reducing repair risk.
- Use online trade-in tools and dealer quotes to refine resale estimates; get 2–3 offers.
- When buying, putting 10–20% down reduces interest paid and avoids negative equity.
- Use consistent mileage assumptions (e.g., 12,000–15,000 miles/year) for both scenarios to ensure fairness.
- Consider tax benefits: businesses may deduct lease payments differently than loan costs; consult a tax pro for specifics.
- Don’t ignore mileage caps on leases; frequent overage charges can exceed any monthly savings.
- Avoid counting on speculative high resale values; overestimate depreciation to be conservative.
- Be cautious with incentives that lower monthly payments but increase contract length or fees, which can raise total cost.
