Boat Loan Calculator

Boat loan rates in 2025 ranged from approximately 6.5% to 12% depending on loan size, vessel age, your credit score, and lender type. New boats financed for over $100,000 often qualify for rates of 6.5 to 8% from dedicated marine lenders. Smaller or used boats typically attract 8 to 12%. Borrowers with credit scores above 720 access the lowest available rates. Credit unions frequently beat banks by 0.5 to 1.5 percentage points.

Boat loan terms range from 2 years for small used vessels up to 20 years for large or luxury new boats over $100,000. Most marine lenders follow a sliding scale: boats under $25,000 get up to 10 years; $25,000 to $75,000 get up to 15 years; over $75,000 may qualify for 20 years. A longer term lowers the monthly payment but significantly increases total interest paid over the life of the loan.

Most marine lenders require 10 to 20% down on a boat loan. A 10% down payment is the common minimum for qualified borrowers, while 20% typically unlocks the best available rates and terms. For a $50,000 boat, that means $5,000 to $10,000 down. Some lenders offer zero-down financing for new boats at promotional rates, but these often require excellent credit and come with restrictions.

Yes, but the rate will be significantly higher. Borrowers with scores below 620 typically pay 12 to 18% or more, which can nearly double the total cost of the loan compared to a borrower at 720 or above. On a $40,000 loan over 10 years, the difference between 8% and 15% is over $25,000 in total interest. If your credit score is below 650, improving it before applying can save thousands of dollars.

Yes, in many cases. The IRS allows interest on a boat loan to be deducted as mortgage interest if the boat qualifies as a second home, meaning it has sleeping quarters, a galley (kitchen), and a head (toilet). This deduction applies to loans secured by the vessel. Consult a tax advisor to confirm eligibility based on your specific situation and the boat's configuration.

A secured boat loan uses the vessel itself as collateral, similar to a car loan or mortgage. This allows lenders to offer lower rates and longer terms because they can repossess the boat if you default. An unsecured personal loan for a boat purchase carries higher rates because there is no collateral. Most borrowers use secured marine loans for vessels over $10,000, while unsecured personal loans may work for smaller boats or dinghies.

A shorter term costs significantly less in total interest but requires a higher monthly payment. On a $75,000 boat at 8%, a 10-year term costs about $36,600 in interest while a 20-year term costs about $83,600. The 20-year term cuts the monthly payment roughly in half but costs $47,000 more in interest. Most financial advisors recommend the shortest term that fits your monthly budget comfortably, typically 10 to 15 years for mid-size boats.

Beyond the monthly loan payment, boat ownership typically adds annual costs of 10 to 15% of the purchase price. These include marine insurance (1 to 1.5% of boat value), storage or marina fees ($1,500 to $10,000 per year depending on region), fuel, routine maintenance (engine service, bottom paint, electronics), and registration fees. A $60,000 boat can easily cost $8,000 to $12,000 per year in ownership expenses beyond the loan.

Use the Loan Comparison mode on this calculator. Enter the same loan amount for both offers, set the rate and term for Loan A and Loan B, and review the side-by-side table. Focus on total paid rather than monthly payment alone. A dealer offering 9.5% for 15 years may have a lower monthly payment than a bank at 7.5% for 10 years, but the dealer offer can cost tens of thousands more in total interest. The comparison table makes this immediately visible.

GAP (Guaranteed Asset Protection) coverage for marine loans pays the difference between the outstanding loan balance and the actual cash value of the boat if it is totaled, sunk, or stolen. Boats can depreciate 10 to 20% in the first year, and if you financed 90% or more of the purchase price, your loan balance can exceed the insurance payout early in the loan term. GAP coverage typically costs $300 to $600 as a one-time add-on and is generally worth it for new boat purchases with less than 20% down.

Yes. Boat loan refinancing works similarly to auto refinancing. If your credit score has improved since the original loan, or if market rates have fallen, refinancing can meaningfully lower your rate and total interest. Marine lenders and credit unions often offer refinance products with minimal fees. Use the Loan Comparison mode to compare your current loan terms against a hypothetical refinance offer to see the total savings before deciding.

Typical boat loan applications require proof of income (pay stubs or tax returns), a credit check, the boat's make, model, year, and hull identification number (HIN), a current survey or appraisal for used boats, and proof of marine insurance or a commitment to insure. Larger loans above $50,000 may also require a sea trial and an ABYC-certified marine survey. Having these documents ready speeds the approval process significantly.
