How it works
A lease-versus-buy calculator built from contract math shows which path truly costs less per year of driving. A lease finances only the vehicle's depreciation during the term - the drop from capitalized cost to residual value - plus a rent charge computed from the money factor on the average of those two figures. Buying finances the whole price, but ends with an asset you can sell. Because the two paths run different horizons, comparing monthly payments flatters the lease every time; the honest yardstick is total cost divided by years driven. This calculator reconstructs the lease payment from the quote's pieces - price, cap-cost reduction, residual percentage, money factor and fees - so you can check whether the dealer's number is fair, then sets it against a loan whose cost nets out the resale equity at payoff. On typical inputs buying wins on cost per year, because ownership ends with something worth selling; leasing wins mainly for drivers who always want a late-model car under warranty, stay well under the mileage allowance, and value predictability over equity. Multiply the money factor by 2,400 before signing anything: it exposes the lease's true interest rate against the loan's APR.Formula
Lease payment = depreciation + (cap cost + residual) x money factor | Buy net cost = down + payments - resale
Tips
- Compare cost per year, never the monthly payment - low payments are what leases are sold on.
- Multiply the money factor by 2,400 to reveal the lease APR and hold it against your loan offer.
- The residual percentage drives everything - high-residual models lease cheaply and depreciate slowly.
- Budget mileage honestly; excess bills run 15-25 cents a mile at return.
- Never roll negative equity or fees into a new lease - you pay depreciation on dead debt.
