What is a Car Lease vs Buy Calculator?
A Car Lease vs Buy Calculator is a comprehensive financial analysis tool that compares the total cost of ownership between leasing and purchasing a vehicle. This calculator evaluates monthly payments, down payments, depreciation, maintenance costs, insurance, and opportunity costs to determine which option provides better financial value based on your specific situation and driving habits.
The decision between leasing and buying a car involves multiple financial factors beyond just monthly payments. This calculator helps you understand the true total cost of ownership (TCO) for both options, including hidden costs like excess mileage fees, wear-and-tear charges, maintenance differences, and the opportunity cost of your down payment investment.
Car Lease vs Buy Calculation Formulas
Car lease vs buy calculations involve complex financial analysis comparing total costs, opportunity costs, and residual values over the ownership period.
Total Cost of Leasing Formula
Total Lease Cost = (Monthly Payment × Lease Term) + Down Payment + Fees + Excess Costs
Total Cost of Buying Formula
Total Buy Cost = Purchase Price + Interest + Insurance + Maintenance - Resale Value
Opportunity Cost Analysis
Net Buy Cost = Total Buy Cost - (Down Payment × Investment Return Rate)
Example: $30,000 car, 3-year comparison:
Lease: $350/month × 36 months + $3,000 down = $15,600 total
Buy: $30,000 - $18,000 resale + $2,000 interest + $1,500 maintenance = $15,500 total
Difference: Leasing costs $100 more over 3 years
How to Calculate Lease vs Buy Decisions
Financial Factor Analysis
Leasing Advantages
- Lower monthly payments: Typically 30-50% lower than financing
- Lower down payment: Often $0-$3,000 vs $5,000+ for buying
- Warranty coverage: Most repairs covered during lease term
- Latest technology: Access to newest features every few years
Buying Advantages
- Ownership equity: Build value instead of renting
- No mileage restrictions: Drive unlimited miles without penalties
- Modification freedom: Customize vehicle as desired
- Long-term savings: No payments after loan payoff
Break-Even Analysis Example
Scenario: $35,000 sedan, 5-year analysis
Leasing (3-year lease + 2-year lease)
- First lease: $389/month × 36 months + $2,500 down = $16,504
- Second lease: $420/month × 24 months + $2,500 down = $12,580
- Total 5-year cost: $29,084
Buying (5-year financing)
- Monthly payment: $550/month × 60 months = $33,000
- Down payment: $5,000
- Total payments: $38,000
- Minus resale value: -$15,000
- Net 5-year cost: $23,000
Result: Buying saves $6,084 over 5 years

Frequently Asked Questions
Is it better to lease or buy a car for total cost ownership?
Buying is typically cheaper long-term if you keep the car for many years, while leasing can be more cost-effective if you prefer newer cars with latest features and don't drive excessive miles. The break-even point is usually around 4-6 years of ownership.
What factors make leasing more attractive than buying?
Leasing is better when you want lower monthly payments, prefer driving newer cars with warranties, drive less than 12,000-15,000 miles annually, can deduct vehicle expenses for business, or want predictable costs without major repair worries.
How do mileage restrictions affect lease vs buy decisions?
Lease mileage limits (typically 10,000-15,000 miles/year) with penalties of $0.15-$0.30 per excess mile make buying better for high-mileage drivers. If you drive more than 15,000 miles annually, buying usually provides better value.
What hidden costs should I consider in lease vs buy analysis?
Leasing hidden costs include acquisition fees, disposition fees, excess wear charges, and gap insurance. Buying hidden costs include maintenance after warranty, depreciation, sales tax on full price, and opportunity cost of larger down payment.
How does car depreciation affect the lease vs buy decision?
Cars depreciate 20-30% in the first year and 60% over five years. Leasing protects you from depreciation risk since you return the car, while buying exposes you to depreciation but allows you to benefit if the car holds value better than expected.
