What interest rates are typical for boat loans?

Boat loan rates typically range from 6–12% depending on your credit score, loan amount, and whether the boat is new or used. New boats with excellent credit can qualify for rates near those of auto loans.

How long can I finance a boat?

Boat loan terms commonly range from 2 to 20 years. Smaller loans are typically 2–5 years, while larger loans over $50,000 can extend to 15–20 years.

Can I use a home equity loan for a boat?

Yes, and home equity loans often offer lower rates. However, your home serves as collateral, meaning you risk foreclosure if you default. Marine-specific financing keeps the risk separate.

Does this calculator include insurance or registration?

No. Boat insurance, registration fees, slip fees, and maintenance costs are not included. Budget an additional $1,500–$3,000+ per year for these ongoing costs.

Is boat loan interest tax deductible?

If the boat has a sleeping berth, a galley (kitchen), and a head (toilet), it may qualify as a second home, making the mortgage interest deductible. Consult a tax advisor for your specific situation.

💡 See it in action — a real example

A $45,000 boat with $10,000 down at 7.5% for 15 years: P = $35,000, r = 0.625%, n = 180. Monthly payment ≈ $324. Total interest ≈ $23,280.
