Boat ownership costs more than purchase price suggests. Mooring (2,000-5,000/year), maintenance (5-10% of boat value), insurance (300-1,500), and depreciation (5-15% annually) add up significantly.
40,000 boat + 3,000 mooring + 3,000 maintenance + 600 insurance + 3,000 depreciation × 8 years = 115,600 lifetime. Annualised 14,450 - roughly 36% of purchase price per year.
The 'boat rule of thumb' says annual ownership equals 10-20% of purchase price. Check specific boat category (sailing yachts more maintenance-heavy; small powerboats less mooring-intensive).
Quick example
With purchase price of 40,000 and annual mooring of 3,000 (plus annual maintenance of 3,000 and annual insurance of 600), the result is 14,600.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Purchase Price, Annual Mooring, Annual Maintenance, Annual Insurance, and Annual Depreciation. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
What's happening under the hood
Annualised = (purchase + running × years) / years. Running annual = mooring + maintenance + insurance + depreciation. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Why run the numbers before the purchase
Big purchases reward slow thinking. The calculation here is fast; the decision it informs isn't. Running this before you shop is the cheapest way to avoid the "seemed fine in the showroom" trap.
What this doesn't capture
Purchase decisions rarely come down to payback alone. Reliability, time saved, enjoyment, and alternatives outside the calculation all matter. The figure gives you the money side cleanly so you can weigh it against everything else honestly.
£40,000 £ boat + running × 8 yearsyrs = $14,600.00/yr.
