Pontoon Boat Loan Calculator
Calculate the monthly payment and amortization on a pontoon boat loan. Marine loans run longer than auto loans, which lowers the payment but raises total interest.
For reference, the U.S. Prime Rate is 7.00% per annum in the Federal Reserve H.15 release as of 2026-10-13, which describes Prime as one of several base rates used by banks to price short-term business loans. Enter the actual rate your lender offered. Prime is context only, not your rate, and is never used in the calculation.

How this estimate is built
The model
Figures assume a fixed rate and equal monthly payments; sales tax and trade-in are optional and adjust the financed amount. Some pontoon boat loans use balloon, seasonal or simple-interest structures this tool doesn’t model. The interest rate is the one you enter from your lender, not a figure we set. Confirm any offer with the lender.
