How much does a boat loan cost per month?

Figures on this page are illustrative examples based on typical market conditions and an assumed 6.5 percent rate. They are not offers. Your terms are set by your lender.

A boat loan payment is what you pay each month to repay principal plus interest. For a typical marine loan, about $370 to $660 per month for every $50,000 borrowed, depending on term and rate. In one sentence: a $100,000 loan over 15 years at an assumed 6.5% rate runs about $871 a month. The two inputs you control most are your down payment and the loan term.

A boat loan typically costs between $370 and $660 per month for every $50,000 borrowed, depending on the term length and your interest rate. A $100,000 loan over 15 years at a 6.5 percent rate comes to about $871 per month.

Your exact payment depends on four inputs: the purchase price, your down payment, the loan term, and the rate your lender offers. Model your own numbers with the boat loan calculator below.

Key points
  • Roughly $370–$660 per month per $50,000 borrowed.
  • Four inputs drive it: price, down payment, term, and rate.
  • Longer terms cut the monthly payment but raise total interest.
  • A $100,000 loan, 15 years, 6.5%: about $871 per month.

The four inputs that set your payment

Purchase priceThe starting point. Everything else works from here.
Down paymentMost marine lenders look for 10 to 20 percent down. Older vessels and larger loans often require more.
Loan termMarine loans run longer than auto loans. Loans above $50,000 commonly support 15 to 20 year terms. A longer term lowers the monthly payment and raises the total interest paid.
Interest rateSet by your lender based on the loan size, the vessel, and your credit profile. The calculator on this page uses an assumed rate of 6.5 percent. Your actual rate is set by your lender.

What the term does to a $100,000 loan at 6.5 percent

TermMonthly paymentTotal interestTotal paid
10 years$1,135.48$36,257.57$136,257.57
15 years$871.11$56,799.33$156,799.33
20 years$745.57$78,937.55$178,937.55

The pattern is simple. Ten years costs $390 more per month than twenty, and saves you about $42,680 in interest over the life of the loan.

Costs the loan payment does not cover

The loan is not the whole monthly picture. Budget separately for insurance, dockage, fuel, and maintenance. Unlike a mortgage, none of these are escrowed into your payment. If you need insurance, you can apply for it on YachtWay via MasterCover. For pre-owned vessels, plan for a marine survey before closing. Your lender will require one.

Takeaways

  • Cost scales with the amount borrowed. Reduce it with a larger down payment.
  • Stretching the term lowers the payment but you pay more interest overall.
  • Rate matters, but term usually swings the monthly number more.
  • Model price, down payment, term, and rate together before you shop.

Frequently asked questions

Expect roughly $370 to $660 per month for every $50,000 borrowed, depending on the term and rate. As an example, a $100,000 loan over 15 years at an assumed 6.5 percent rate comes to about $871 per month.

$50,000. Purchases below that amount are typically financed through personal loans, which carry shorter terms and higher rates.

Most marine loans use fixed rates, so your payment stays the same for the life of the loan.

Yes. Older vessels typically face shorter maximum terms and higher rates, both of which raise the monthly payment.

No. Auto loans rarely run past 7 years. Marine loans commonly run 10 to 20 years, which changes the math significantly.
