About the Boat Loan Calculator
This calculator estimates monthly boat payments, total loan amount, sales tax, upfront payment, total interest, total cost, and an amortization schedule. It supports the common inputs used for marine financing: boat price, down payment, trade-in value, sales tax, fees, loan term, and interest rate.
Amount financed
Boat price plus tax and financed fees, less down payment and trade-in value.
Upfront payment
Cash down, trade-in value, and fees that are not rolled into the loan.
Amortization
Each payment is split between interest and principal. Early payments usually include more interest.
How to use this calculator
Enter the boat price, down payment, trade-in, taxes, fees, loan term, and APR. Choose whether fees are included in the loan, then review the monthly payment, total interest, total cost, and schedule.
