About the Lease or Buy Car Calculator

The Lease or Buy Car Calculator is a free tool that compares the true total cost of leasing versus buying a vehicle, including depreciation, opportunity cost, fees, and insurance differences that most calculators ignore. Enter the vehicle details and your financial situation to see an honest side-by-side comparison.

Why we built this

Most car cost calculators oversimplify the lease vs buy question. We built this to give people a complete picture of the real long-term costs before making one of the biggest financial decisions they will make.

Accuracy and limitations

Cost estimates are based on the inputs you provide and standard industry depreciation assumptions. Actual costs vary based on your specific vehicle, insurance rates, financing terms, and local taxes. Always consult a financial advisor before major vehicle purchases.
