Boat Cost of Ownership Calculator

The total cost of boat ownership typically ranges from 10% to 20% of the purchase price per year. For a $50,000 boat, expect $5,000–$10,000 annually covering insurance, marina fees, fuel, maintenance, and registration. Use our calculator above for a personalized estimate based on your specific boat, location, and usage.

Marina or dock fees are often the single largest ongoing expense, especially in coastal areas where wet-slip rates can exceed $30 per foot per month. For a 25-foot boat, that is $750/month or $9,000/year. Trailering and storing at home can eliminate this cost entirely.

Boat insurance typically costs 1% to 2% of the boat's value per year. A $50,000 boat might cost $750–$1,000 annually. High-performance boats and personal watercraft have higher rates, while sailboats and pontoons are often cheaper to insure.

Pontoon boats are generally cheaper to own. They have lower insurance rates, more fuel-efficient engines, and simpler maintenance. Center consoles with large outboards consume more fuel and cost more to maintain, but offer greater versatility for fishing and offshore use.

Fuel costs vary by engine size. A pontoon with a 115HP outboard burns about 6–8 gallons per hour ($25–35). A center console with twin 300HP outboards might burn 30–40 gallons per hour ($120–160). Sailboats under power use minimal fuel.

New boats typically depreciate 15–20% in the first year, then 5–10% per year through year five. After 10 years, depreciation slows to 2–3% annually. Well-maintained boats from brands like Boston Whaler and Grady-White hold their value better than average.

Financing makes sense if you can invest cash at a higher return than the loan rate. Marine loan rates typically range from 5% to 9%. Putting at least 20% down gets you better rates and helps avoid being underwater as the boat depreciates.

It depends on usage. A $50,000 boat costing $8,000/year works out to $80/hour at 100 hours/year, but only $32/hour at 250 hours. The more you use your boat, the lower the per-hour cost — a strong argument for buying a boat you will actually use often.
