How this calculator works

Payment = (P − B ÷ (1 + r)^n) × r ÷ (1 − (1 + r)^−n). P is the amount financed, B is any balloon due at the end, r is the APR divided by 12, and n is the number of monthly payments. At 0% APR the payment is simply (P − B) ÷ n. This is the standard amortization formula for a fixed-rate loan with monthly payments.

Amount financed = price − down payment − trade-in, plus sales tax and fees if you roll them into the loan. How trade-ins and sales tax work on a truck purchase depends on your state, so enter your own rate and check the box that matches your state's rule.

Total cost of the truck = cash at signing + trade-in value + every payment + the balloon. The difference between that and the price is what financing costs you.

Lease vs buy adds up everything you'd pay over the loan term both ways. On the buy side that's the loan cost plus maintenance, minus what the truck is worth at the end. On the lease side it's the money due at signing, lease payments, and maintenance. If you buy the truck out at the end, it also adds the buyout and subtracts the resale value. These are plain totals. They don't count interest you could earn on cash or the tax treatment, which differs between leases and loans.
