Boat Loan Calculator
Monthly payment, total interest, and amortization for a US marine loan. Includes down payment, trade-in, sales tax, and dealer fees.
FINANCECalculate monthly payment, total interest, and full amortization for a boat loan in the United States. Marine lenders typically offer 10-20 year terms for new boats and 7-10 years for older or smaller craft. Includes down payment, trade-in, sales tax, dealer fees, and an affordability check against the 8-10% of pre-tax monthly income rule of thumb.
Boat loans use standard amortization math but with marine-specific terms: longer durations (15-20 years versus 5-7 for cars), higher APR (1-3% above auto loans), and stricter underwriting (often 700+ FICO required). Total interest on a 20-year boat loan can exceed the boat purchase price. Sales tax is collected by most states at standard rates; NC, RI, and AL have boat-specific caps. Total cost of ownership runs about 10% of purchase price annually for insurance, slip fee, fuel, and maintenance on top of the loan payment.

Marine industry rule of thumb: monthly boat payment + insurance + storage + fuel should not exceed 8-10% of pre-tax monthly income.
How Boat Loans Differ from Auto Loans
Boat loans share the amortization math of auto loans but have several quirks. Terms run much longer - 15-20 years for new boats versus 5-7 for cars - because boats are bigger purchases and the lower monthly payment is the selling point. The longer term means substantially more total interest paid: a 20-year boat loan can cost more in interest than the boat itself.
Marine lenders treat collateral risk seriously. Boats depreciate quickly (40-60% in first 5 years for new), and a boat in financial distress can sail away or sink. Expect higher down payment requirements (10-20% typical), higher APR (1-3% above comparable auto), stricter credit standards (often 700+ FICO), and shorter terms on older boats. Survey and marine insurance are usually required.
Total cost of ownership is much more than the loan. Annual rule of thumb: 10% of purchase price covers insurance ($500-2,000/yr), storage/slip ($1,000-6,000/yr), fuel, maintenance, and winterization. A $50,000 boat realistically costs $5,000+ per year to keep on the water on top of the loan. Many buyers underestimate this and end up "boat poor" within 2-3 years.
Estimate only. Actual boat loan offers depend on credit score, age of boat, lender type, and current marine lending rates. Always shop multiple lenders including credit unions and dedicated marine financiers (TridentFunding, Essex Credit).
