Boat Insurance Cost Calculator

What drives the cost of boat insurance

Boat insurance is not legally required in most states the way auto insurance is, but marinas, lenders, and lakefront communities commonly require proof of liability coverage before you can dock or finance a boat.

Pricing depends heavily on where you keep the boat and how much it is worth, the two factors this calculator uses. According to Progressive's own published rate data, covering the 2023-2024 policy period and weighted by how many policies it holds in each state, the national spread runs from a $301 average in the cheapest states to $657 in the most expensive.

Location is the bigger structural factor. Progressive groups states into three cost tiers rather than publishing a rate for every state individually: a low-cost tier averaging $301 a year (largely inland, lower-hurricane-risk states like Wisconsin, Minnesota, and Iowa), a medium tier averaging $400, and a high-cost tier averaging $657 that includes Florida, Louisiana, and most of the Gulf and Atlantic coastal states along with a handful of others.

Storm exposure, the length of the boating season, and regional theft and claims rates all feed into that spread.

Boat value is the other major lever. Multiple independent boat insurance sources describe pricing as roughly 1% to 5% of the boat's current market value per year, similar in spirit to how homeowners insurance scales with a home's replacement cost.

This calculator applies an estimated 1.5% of value per year, in the middle of that commonly-cited range, scaled by your state's cost tier relative to the national average across all three tiers.

No single source publishes a state-by-state value curve, so this scaling is applied uniformly and disclosed as an estimate rather than presented as state-specific precision.

A few things this calculator cannot price in: boat type (a personal watercraft, bass boat, sailboat, and cabin cruiser all carry different risk profiles), the boat's age and horsepower, your boating safety course completion, and your claims history.

All of these move an actual quote up or down from this estimate, sometimes substantially, which is why insurers require a real application rather than pricing purely off value and location.

Even a very low-value boat rarely insures for less than around $200 a year, since insurers have fixed costs to underwrite and service any policy regardless of how small the risk is. This calculator applies that floor so a cheap, small boat does not produce an unrealistically tiny number.
