Thinking of buying a boat? Use our calculator to find out how much you might owe based on your loan amount, term and interest rate. This can help you compare offers to find the best deal for you.

Key takeaways

  • Boat loan interest rates typically start between 4% and 6%, with the lowest rates reserved for borrowers with high incomes and excellent credit — ideally a score of at least 700.
  • Boat loan terms are longer than typical personal loans, averaging 7 to 15 years and sometimes stretching to 20 years, reflecting the higher purchase prices involved.
  • Use the calculator before you apply — entering your loan amount, term and APR gives you both your estimated monthly payment and total interest paid, which lets you compare lender offers on an apples-to-apples basis.
  • Even a small difference in APR adds up significantly over a long term — on a $30,000 loan over 10 years, the gap between a 5% and an 8% rate amounts to thousands of dollars in extra interest.
