What this calculator estimates

Compare the net cost of leasing a vehicle with buying and retaining equity. The calculation runs locally in your browser and is intended for planning and comparison.

How to use it

Enter the requested values, select Calculate, review the headline result and supporting figures, then change one input at a time to compare another scenario.

How the calculation works

Lease cost adds upfront, monthly and lease-end charges. Buy cost adds down payment and payments, then subtracts estimated ending equity.

Input checklist

The Lease vs Buy Car Calculator uses the values shown in its form. Before calculating, check each input independently so an incorrect unit or time period does not carry through to the final result.

• Lease upfront cost ($): verify that this value uses the unit, period, and definition shown by the calculator.
• Lease monthly payment ($): verify that this value uses the unit, period, and definition shown by the calculator.
• Comparison months: verify that this value uses the unit, period, and definition shown by the calculator.
• Lease-end fees ($): verify that this value uses the unit, period, and definition shown by the calculator.
• Buy down payment and fees ($): verify that this value uses the unit, period, and definition shown by the calculator.
• Buy monthly payment ($): verify that this value uses the unit, period, and definition shown by the calculator.
• Estimated vehicle equity at end ($): verify that this value uses the unit, period, and definition shown by the calculator.

Practical interpretation

Use the Lease vs Buy Car Calculator result as the answer to the specific inputs entered, not as a universal value. The calculation currently described on this page is: Lease cost adds upfront, monthly and lease-end charges. Buy cost adds down payment and payments, then subtracts estimated ending equity. Change one important input at a time when comparing scenarios so you can see which assumption actually drives the difference.

Checks before relying on the result

The result depends on the values and units entered. Recheck the inputs and compare the estimate with the real-world source or rule that applies to your situation. Recalculate when a key value changes, and keep the original inputs with the result if you need to reproduce or compare the calculation later.

Important limitations

Mileage charges, maintenance, taxes, financing differences and resale uncertainty may materially change the comparison.
