Lease vs. Buy Calculator

Compare the estimated cost of leasing vs. buying a vehicle.

Compare a financed vehicle purchase with a lease over the same period. Adjust the loan rate, resale value, residual value, money factor, taxes, fees and upfront payments to explore different scenarios.

The comparison uses the lease term as the period for evaluating both options.

Cost Comparison

Compare buying and leasing over the same period

The purchase calculation subtracts estimated vehicle equity at the end of the comparison period.

Key Assumptions

Small changes can materially affect the comparison

Resale value, lease residual and financing terms are especially important.

Estimated resale value $0 Estimated value of the purchased vehicle after the comparison period.
Lease residual value $0 Contractual estimated value used in the lease calculation.
Purchase interest paid $0 Estimated auto-loan interest paid during the comparison period.
Lease rent charge $0 Estimated financing component of the lease before taxes.
Understanding Lease vs. Buy

Leasing and buying work very differently

Buying with an auto loan means you are financing ownership of the vehicle. As the loan balance declines, you may build equity if the vehicle is worth more than the remaining debt.

Leasing generally means paying for the vehicle's expected depreciation during the lease period, plus a financing charge, taxes and applicable fees.

Why resale value matters when buying

At the end of the comparison period, a purchased vehicle still has value. This calculator subtracts estimated vehicle equity from the amount you have spent so the buy side is not treated as though the vehicle were worth zero.

What is a lease residual?

The residual value is the estimated vehicle value used by the leasing company at the end of the lease. It is commonly expressed as a percentage of MSRP.

What is a money factor?

A money factor is used to calculate the financing portion of a lease. Multiplying the money factor by approximately 2,400 gives a rough APR equivalent for easier comparison, although the two are not identical.

Mileage and wear can matter

Lease contracts can include mileage limits and charges for excess wear. Those potential costs are not automatically included in this calculator because they depend on the individual lease and how the vehicle is used.

How this comparison works

Buy net cost ≈ down payment + payments made − estimated vehicle equity
✓ Negotiated purchase price and vehicle MSRP
✓ Purchase APR, down payment, term, tax and fees
✓ Remaining purchase loan balance after the comparison period
✓ Estimated resale value and purchase equity
✓ Lease residual percentage
✓ Lease money factor and capitalized-cost reduction
✓ Lease acquisition and financed fees
✓ Estimated monthly tax on the lease payment

Actual lease taxation, acquisition fees, disposition fees, incentives, mileage charges and purchase-option terms vary by contract and location.

Lease vs. Buy Calculator FAQ

Frequently asked questions

How does this calculator compare leasing with buying?

The calculator compares estimated costs over the same number of months. On the purchase side, it accounts for loan payments and estimated vehicle equity. On the lease side, it estimates depreciation, rent charge, taxes, fees and upfront capitalized-cost reduction.

Why is estimated resale value included when buying?

A purchased vehicle is an asset that may still have value at the end of the comparison period. Subtracting estimated equity gives a more meaningful cost comparison than counting payments alone.

What is the residual value on a lease?

Residual value is the estimated value assigned to the vehicle at the end of the lease. It is commonly expressed as a percentage of MSRP and affects the depreciation portion of the lease payment.

What is a lease money factor?

The money factor is used to determine the financing or rent charge on a lease. Multiplying the money factor by approximately 2,400 provides a rough APR-style equivalent for comparison.

Does this calculator include excess-mileage charges?

No. Mileage allowances and excess-mileage rates vary by lease. Add any expected mileage or wear charges separately when evaluating a specific offer.

Does the calculator include a lease disposition fee?

Not automatically. Some leases charge a fee when the vehicle is returned. Review the lease offer and include any known additional costs when comparing options.

Why can a lease have a lower monthly payment?

A lease payment is generally based largely on the estimated depreciation during the lease term plus financing charges, rather than financing the entire vehicle purchase price for ownership.

Does a lower monthly payment mean a lease costs less overall?

Not necessarily. Monthly payment is only one component. Upfront cash, vehicle equity, resale value, mileage charges, fees and what happens at the end of the term can all change the comparison.
