For reference, the U.S. Prime Rate is currently 6.75% (source: Federal Reserve H.15, as of 2026-08-13). Lenders price pontoon boat loans as Prime plus a margin set by your credit and term, so the rate you are quoted will usually sit above this. Enter the actual rate a lender offered. This benchmark is context only and never enters the calculation.

How long can you finance a pontoon boat?

Commonly 10 to 15 years depending on the amount; smaller loans finance for shorter terms.

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.
