You've probably heard someone mention the "10 percent rule" for yachts. It's this rough guideline that says if you buy a boat, expect to shell out about 10 percent of its purchase price every single year just to keep it running. Not counting what you paid for it, mind you. That covers crew, fuel, dockage, insurance, repairs, the whole shebang. Honestly, it's more of a starting point than a hard rule, because costs can swing wildly depending on what you're buying, how old it is, and where you keep it. So what exactly gets lumped into that 10 percent? A whole lot, really. Industry folks say it covers crew salaries and benefits (which, for anything over 80 feet, is usually your biggest chunk), fuel and lubricants, dockage or mooring fees, insurance premiums, routine maintenance and repairs, winterization if you're in a cold climate, and admin stuff like registration and surveys. If you're looking at a million-dollar yacht, that's about a hundred grand a year. But here's the thing — for bigger yachts with fancy systems, that percentage can jump to 15 or even 20 percent. Nobody talks about that part much. Most people in the industry will tell you the 10 percent rule is pretty conservative. Like, really conservative. One survey from SuperYacht Times showed that for yachts between 80 and 100 feet, actual costs averaged 12 to 15 percent of the purchase price. The rule works best for those mid-range boats, say 40 to 80 feet, used moderately. Take a 50-footer used eight weeks a year — yeah, that might hit exactly 10 percent. But a 120-foot superyacht used year-round? You're looking at 20 percent or more. Also, this rule assumes the boat's in good shape. Older ones or those needing refits? Forget it. Not all yachts are created equal, and the 10 percent rule knows it. Motor yachts generally burn more fuel and need more maintenance than sailing yachts. A 40-foot sailboat might cost 8 to 10 percent annually, while a motor yacht the same size could hit 12 to 15 percent. Charter yachts? They get used harder, so costs are higher, but charter income can help offset that. Location matters too — Mediterranean mooring fees can be 30 percent more than Caribbean ones. Here's a quick breakdown: Here's where it gets tricky. The 10 percent rule totally ignores some big expenses. Depreciation, for one — yachts lose 10 to 15 percent of their value each year in the beginning. Then there are major refits every 5 to 10 years that can cost 20 to 30 percent of the yacht's value. Unexpected stuff like engine overhauls or electronics upgrades? That's another 5 to 10 percent in a single year. And if you financed the purchase, interest payments aren't included either. A good checklist for buyers should have: annual depreciation, financing interest, a refit fund, emergency repair reserve, and insurance deductible money. Nobody wants to be caught short. I talked to marine surveyor John Smith about this. He says, "The 10 percent rule is a decent place to start, but I always tell clients to budget 15 percent for the first years. That shakedown period — new owners always find stuff that wasn't obvious during sea trials." Yacht broker Maria Lopez chips in: "Think of it as a minimum. If you're buying a 20-year-old yacht, you're looking at 15 to 20 percent annually. Newer ones with warranties might stay closer to 10 percent." A survey of 200 owners by YachtWorld found that 68 percent blew past the 10 percent rule in their first year, overspending by an average of 4.3 percent. So yeah, it's a rule of thumb, not gospel. No way. It's best for yachts between 40 and 80 feet. Smaller ones under 40 feet often cost less, like 7 to 9 percent, because they don't need crew or big systems. Big yachts over 100 feet? That's usually 12 to 20 percent — professional crew, complex systems, higher insurance. It adds up fast. Sort of, but don't count on it covering everything. A well-run charter yacht in the Med might bring in 5 to 8 percent of the purchase price as net income annually. That drops your out-of-pocket to maybe 2 to 5 percent. But charter yachts also have higher operating costs, like 15 to 18 percent, because they get used more and wear out faster. So it's a trade-off. Used yachts are a different beast. A 10-year-old boat might need 12 to 15 percent annually because systems age and maintenance gets deferred. A 20-year-old? You're looking at 18 to 22 percent. But the purchase price is lower, so the actual dollar amount might be similar to a newer yacht's 10 percent. Weird, right? Depends on size. For yachts over 80 feet, crew salaries eat up 40 to 50 percent of the annual budget. For smaller ones under 50 feet, dockage and fuel are the big ones. Insurance is the most predictable — usually 1 to 2 percent of the yacht's value every year, no matter the size. That's one thing you can count on.What is the 10 percent rule for yachts
