8.00 is a placeholder, not an offer or a typical rate.

Figure payments over more years than the term and the balance left at the end is a balloon.

Tax, fees and insurance
Rates and caps come from each state's tax agency; local add-ons are not included. See the table.
Use your agent's quote. Lenders require hull coverage naming them as loss payee.

Illustration only, not an offer: the starting values are examples, and your APR, term and payment will differ. Estimates come from the numbers you enter. Your lender's disclosures control.

Before you sign

  1. Compare what lenders publish

    Terms, loan sizes, age limits and credit rules as nine lenders publish them on their own pages, each dated.

  2. Check your state's boat sales tax

    Florida caps state tax at $18,000 and North Carolina at $1,500, so the state you buy in can change the bill by thousands of dollars.

  3. Set the down payment

    Pricing can hinge on loan-to-value: M&T's bottom-of-range boat APR needs a loan of 80% of value or less.

  4. Decide on a balloon, or not

    A lower payment figured over more years leaves a lump sum due at the end, and you need a plan for it.

  5. Book the marine survey

    Navy Federal requires a survey on every used boat, and the value in the report sets your loan-to-value.

  6. Sort out documentation or title

    Boats of five net tons or more can be Coast Guard documented and carry a preferred ship mortgage.

Yacht.Loans is a calculator and a set of reference pages for people buying a boat in roughly the $100,000 to $3 million range with a loan. It’s built for the stretch between finding the boat and signing the purchase agreement, when you’re comparing lenders and need the real monthly cost, not a teaser figure.

The calculator does a few things most boat loan calculators skip. It lets you set the term and the payment schedule separately, so you can see the balloon a shorter term leaves behind. It applies the state sales tax rate and the cap for the states we’ve confirmed, so a $600,000 boat in Florida shows $18,000 of state tax rather than $36,000. It adds closing costs and your insurance premium, and it draws the loan balance year by year so you can see what you’d owe if you sold early.

Where the numbers come from

Every figure on this site comes from a primary source: a lender’s own boat loan page, the Code of Federal Regulations, the U.S. Code, the Coast Guard’s National Vessel Documentation Center, IRS Publication 936, or a state statute or tax agency. Each one is linked and dated with the day we read it, October 24, 2026 for the current set. Where a source didn’t say something, we leave it out. You won’t find typical survey costs, insurance premiums or “average” boat loan rates here, because we haven’t found a primary source for any of them. The Federal Reserve’s consumer credit release, for instance, publishes no boat loan rate series.

Lender terms change, sometimes daily. Treat the lender terms page as a record of what each lender published on that date, and check the lender’s current disclosure before you rely on it.

The calculator’s 8.00% APR is a placeholder so the arithmetic has something to work with. It isn’t an offer or a typical rate. Put in the APR from your own quote. For a real rate, ask lenders for written quotes. If you have a question about your numbers, send them to us and a person will reply by email. Yacht.Loans isn’t a lender and no lender pays it; the disclosures say more.

Questions people ask

What APR should I put in the calculator?

The one from your own written quote. The 8.00% preset is a placeholder for the arithmetic, not an offer or a typical rate.

How long can you finance a boat?

Of the lender pages we read on October 24, 2026, the longest published term was 240 months, from Truist's marine loan, M&T Bank and Southeast Financial. Navy Federal and DuPage Credit Union publish 180 months. Each lender's published APR range, where it gives one, is beside its terms on the lender terms page.

How much down payment do boat lenders want?

The National Marine Lenders Association says its members' down payments are typically in the 10 to 20 percent range. Navy Federal advertises options with no down payment.

Is Yacht.Loans a lender?

No. Yacht.Loans doesn't make loans or credit decisions. If you send us your numbers, a person replies by email; nothing is passed to a lender. No lender pays Yacht.Loans.

Does the calculator include local sales tax?

No. It applies the state-level rate and cap for the states listed. County and city taxes can be extra; enter your own combined rate if you know it.

Have a question about your numbers?
