How the boat loan calculator works

The loan amount is the boat price minus the down payment and trade-in, plus anything owed on the trade-in and, if you choose, the sales tax and fees. The payment uses the standard installment formula with the rate divided by 12.

Boat loans often run longer than car loans, 10 to 20 years for bigger boats, which lowers the payment but adds a lot of interest. Lenders usually expect 10% to 20% down.
