How This Calculator Works
Calculation methodology and assumptions
The true cost of boat ownership goes far beyond the purchase price. This calculator accounts for financing (standard amortization), insurance (typically 1-2% of boat value), marina/slip fees ($200-$600+/month depending on location), maintenance (industry rule of thumb: 10% of boat value per year), fuel costs, and winterization. The "10% rule" — spending about 10% of the boat's value annually on maintenance — is a widely accepted estimate.
Frequently Asked Questions
How much does it really cost to own a boat?
A common rule is that annual operating costs equal about 10-15% of the boat's purchase price. A $50,000 boat costs roughly $5,000-$7,500/year to maintain, plus loan payments, marina fees, insurance, and fuel — often totaling $15,000-$20,000/year.
What is the 10% rule for boats?
The 10% rule suggests budgeting about 10% of your boat's value per year for maintenance and repairs. A $50,000 boat would need about $5,000/year for routine maintenance, repairs, and unexpected issues.
Is boat insurance required?
Boat insurance is not legally required in most states, but marina operators and lenders typically require it. Coverage typically costs 1-2% of the boat's value per year.
