Cost Breakdown
Tip: Include insurance and maintenance estimates for a more accurate comparison.
How to Use This Tool
Enter the car price, down payment, loan term, and interest rate for the buy option. For leasing, input the lease term, monthly payment, and estimated residual value. Set annual miles driven and select vehicle type and driving conditions for context. Click Calculate to see a side-by-side cost breakdown. Use Reset to clear all fields.
Formula and Logic
The buy cost is calculated as the down payment plus the total of monthly loan payments, using the standard amortization formula: Monthly Payment = Principal * (r(1+r)^n) / ((1+r)^n - 1), where r is the monthly interest rate and n is the loan term in months. Lease cost includes the down payment plus total monthly lease payments. Cost per mile is estimated by dividing total costs by the miles driven over the loan or lease period. The tool compares these totals to show which option is more economical.
Practical Notes
Driving conditions affect fuel efficiency and maintenance costs—city driving may increase wear, while highway driving can reduce it. Consider maintenance intervals; leased vehicles often require fewer out-of-pocket repairs during the term. Insurance factors may differ between leasing and buying, as leased cars sometimes need higher coverage. Depreciation curves favor buying long-term, as leased vehicles are returned, but buying allows equity build-up. For electric vehicles, factor in charging costs and incentives.
Why This Tool Is Useful
This tool helps you make a data-driven decision by highlighting the financial trade-offs between leasing and buying. It accounts for real-world variables like mileage and vehicle type, which impact total ownership costs. Whether you're a car owner, fleet manager, or enthusiast, it provides clarity on long-term expenses.
