How to Use This Tool
Start by entering all relevant buy-side costs: the vehicle’s purchase price, any down payment, loan APR, loan term, how long you plan to own the car, estimated resale value, and annual recurring costs like maintenance, fuel, and insurance.
Next, fill in the lease-side details: lease term, monthly payment, any upfront down payment, acquisition and disposition fees, mileage allowance, your expected annual mileage, excess mileage fees, and recurring lease costs for maintenance, fuel, and insurance.
Click the Calculate Comparison button to see a detailed breakdown of total costs for both options. Use the Reset All button to clear all inputs and start over. You can copy results to your clipboard using the copy button in the results section.
Formula and Logic
Buy cost calculations use standard amortization logic for auto loans:
- Monthly loan payment = (Loan Principal * Monthly APR * (1 + Monthly APR)^Loan Term Months) / ((1 + Monthly APR)^Loan Term Months - 1)
- Loan Principal = Purchase Price - Buy Down Payment
- Monthly APR = Annual Loan APR / 12 / 100
Total buy costs include all loan payments made during the ownership period, down payment, total maintenance, fuel, and insurance costs for the ownership period, minus the estimated resale value of the vehicle at the end of the ownership period.
Lease cost calculations include:
- Total lease payments = Monthly Lease Payment * Lease Term (Months)
- Excess mileage costs = Max(0, (Expected Annual Mileage * Lease Years) - (Annual Mileage Allowance * Lease Years)) * Excess Mileage Fee per Mile
Total lease costs include all lease payments, upfront fees, excess mileage charges, and recurring maintenance, fuel, and insurance costs for the full lease term.
Practical Notes
Automotive-specific factors to consider when using this tool:
- Depreciation curves vary by vehicle: luxury cars and electric vehicles often lose value faster in the first 3 years than economy models.
- Lease agreements often include maintenance coverage for the first 2-3 years, so lease maintenance costs are typically lower than buy costs.
- Insurance rates are usually higher for leased vehicles, as lenders require full coverage including collision and comprehensive.
- Excess mileage fees can add up quickly: driving 3,000 extra miles per year at $0.25 per mile adds $750 per year to lease costs.
- Resale value estimates should account for vehicle condition, mileage, and market demand at the time of sale.
Why This Tool Is Useful
Most lease vs buy comparisons only look at monthly payments, ignoring long-term costs like maintenance, fuel, insurance, and resale value. This tool gives a complete financial picture for drivers, fleet managers, and auto enthusiasts making vehicle acquisition decisions.
It accounts for real-world variables like mileage overage fees and depreciation, helping you avoid unexpected costs. Fleet managers can use it to compare total cost of ownership for multiple vehicles, while individual drivers can test different scenarios (e.g., shorter ownership periods, higher mileage) to find the best option for their needs.
Frequently Asked Questions
Should I include sales tax in the purchase price?
Yes, enter the total out-the-door purchase price including sales tax, registration, and title fees in the Purchase Price field to get an accurate cost comparison.
What if I plan to lease multiple times instead of buying?
This tool compares a single lease term to a single buy period. For multiple consecutive leases, calculate the total cost of each lease over the same ownership period as the buy option and sum them for an accurate comparison.
How do I estimate resale value accurately?
Use resources like Kelley Blue Book or Edmunds to look up the current value of your vehicle, then apply an average annual depreciation rate of 15-20% for the first 5 years of ownership.
Additional Guidance
When comparing lease vs buy, also consider non-financial factors: leasing gives you access to newer vehicles with updated safety features every few years, while buying lets you modify the vehicle and drive without mileage restrictions.
For fleet managers, buying may be more cost-effective for high-mileage vehicles, as lease mileage allowances are often too low for commercial use. For drivers who want lower monthly payments and don't plan to keep the vehicle long, leasing is often the better choice.
Always get quotes for loan APR and lease terms from multiple lenders or dealerships before making a decision, as rates can vary significantly between providers.
