About BoatMath

BoatMath is built around a simple question: you can afford the boat, but can you afford owning it? BoatMath helps boat shoppers explore the costs that sit beyond the purchase price.

Our downloadable spreadsheet bundle brings financing, fuel, storage, insurance, maintenance, and repair reserves into one place. Compare two boats and keep cash expenses separate from optional depreciation using your own estimates.

BoatMath is a budgeting tool, not personalized financial advice or a model-specific service manual. There are no live fuel prices or marina-rate databases; the assumptions stay in your hands.
