FinanceEstimate future value and interest earned from principal, rate, time, and compounding frequency.
- What will my savings be worth?
- How much interest will I earn?
Compare leasing and buying over the same horizon, including payments, mileage, financing, depreciation, and equity.
Change the inputs that matter to your decision. Optional assumptions stay collapsed until you need them.
Compare both paths or focus the inputs on one side of the decision.
Enter the payment, term, upfront amount, and mileage assumptions.
Model financing, ownership duration, and vehicle value.
Apply mileage, insurance, and maintenance assumptions to the comparison.
Buy has lower monthly cost. Lease is $524.00 per month in this model; buy is $324.34 after modeled equity.
This is a scenario comparison, not a recommendation. Change the term, mileage, financing, and value assumptions to test the decision's sensitivity.
Planning estimate. Depreciation is a simplified heuristic; taxes, fees, registration, incentives, residual value, and end-of-lease charges may change the actual result.
Practical notes about the inputs, assumptions, and result.
Not necessarily. Monthly cost is one comparison. Mileage limits, flexibility, ownership equity, taxes, fees, maintenance, and your expected time with the vehicle also matter.
This model uses a simplified depreciation heuristic to show remaining vehicle value. Use a vehicle-specific residual or resale estimate for a more precise scenario.
