Yearly cost calculator
Replace the sample numbers with your own.
The costs people forget
- Insurance, which most marinas and many HOAs require
- Registration and, in some states, personal property tax
- Winterization and spring commissioning
- Battery replacement, fuel stabilizer, and shrink wrap
- Repairs from sitting: seals, fuel systems, and trailer tires
Depreciation
A boat that sits usually loses value faster than one that is used and maintained. Every season it waits is a season of wear without use.
Where the money goes, by storage type
- Home driveway: insurance, registration, maintenance, and possible HOA issues
- Outdoor storage lot: monthly rent plus the above
- Indoor or dry stack: higher monthly rent
- Marina slip: slip fees, electricity, bottom cleaning, and haul-outs
The cost of waiting
Every season a boat sits, its value usually drops while the costs keep coming. The calculator shows the cash side; the hidden cost is depreciation.
Using your total
Compare your yearly total with what the boat might sell for. If carrying it for one more year costs a large share of its value, it may be time to decide.
Questions
Are these numbers typical?
The defaults are placeholders. Replace them with your own bills for an accurate total.
Does storing at home avoid most of these costs?
It removes storage fees, but insurance, registration, and maintenance continue, and many HOAs restrict boats in driveways.
What happens to these costs if I donate?
They stop once the boat is transferred. Fees owed up to the transfer date stay with you.
Does insurance drop if the boat is laid up?
Some insurers offer lay-up discounts. Ask yours.
Should I include loan payments?
If you are still paying a loan, yes. It is part of what the boat costs you.
