How Much Does a Boat Cost Per Month? Full Breakdown by Size (2026)
The short answer: expect to spend $400-$800 per month for an 18-foot boat, $700-$1,300 for a 22-footer, $1,000-$1,800 for a 26-footer, and $1,500-$3,000+ for a 30-foot or larger boat. Those numbers include the loan payment, insurance, storage, fuel, maintenance, and registration — everything it actually costs to own and operate a boat on a monthly basis.
The longer answer depends on a dozen variables: what size boat you buy, how much you put down, where you keep it, how often you use it, and whether you’re in salt water or fresh. This guide breaks down every recurring cost line by line, with real dollar ranges by boat size, so you can budget accurately before you buy.

The Seven Monthly Costs of Boat Ownership
Every boat owner pays some combination of these seven categories. Some are fixed (you pay them whether you use the boat or not), and some are variable (they scale with how much you run it). We’ll break down each one, then put it all together at the end.
1. Loan Payment
For most buyers, the loan payment is the single largest monthly expense. Boat loan rates in 2026 typically range from 6.5% APR (excellent credit, 740+) to 10-12% APR (fair credit, 640-680). Terms run from 10 to 20 years depending on the loan amount, with 12-15 year terms being the most common.
Here’s what monthly payments look like at current rates, assuming 15% down and a 12-year term at 8% APR:
| Purchase Price | Down Payment (15%) | Loan Amount | Monthly Payment |
|---|---|---|---|
| $18,000 | $2,700 | $15,300 | $166 |
| $30,000 | $4,500 | $25,500 | $276 |
| $50,000 | $7,500 | $42,500 | $460 |
| $75,000 | $11,250 | $63,750 | $690 |
| $100,000 | $15,000 | $85,000 | $920 |
| $150,000 | $22,500 | $127,500 | $1,380 |
Ways to lower your payment: Put more money down, improve your credit score before applying, shop multiple lenders (credit unions often beat marine lenders by 0.5-1.0%), or extend the term to 15 years. A 15-year term on a $42,500 loan at 8% drops the payment from $460 to about $406 — but you’ll pay roughly $15,000 more in total interest over the life of the loan.
Pro tip: If you’re buying a used boat in the $20,000-$40,000 range from a dealer, you can often finance through the dealer’s lending partners at competitive rates. Browse boats for sale on FindABoat to see what’s available from verified dealers.
2. Insurance
Boat insurance is cheaper than most people expect. A standard comprehensive policy (covering damage, theft, liability, and medical payments) costs roughly 1-2% of the boat’s value per year. That means:
| Boat Value | Annual Premium | Monthly Cost |
|---|---|---|
| $15,000-$25,000 | $250-$450 | $21-$38 |
| $25,000-$50,000 | $450-$800 | $38-$67 |
| $50,000-$100,000 | $800-$1,400 | $67-$117 |
| $100,000-$200,000 | $1,400-$2,500 | $117-$208 |
Factors that affect your rate: boat type (performance boats and sailboats cost more), where you boat (coastal and hurricane zones are higher), your boating experience, whether you’ve completed a boating safety course, and your claims history.
Saltwater vs. freshwater matters. A 22-foot center console kept in coastal Florida may cost $600-$900/year to insure. The same boat used exclusively on an inland lake in Tennessee might run $350-$500/year.

3. Marina Slip or Storage
Storage is the expense that surprises most first-time boat owners. It varies enormously by region and method:
Storage Options and Costs
- Trailer at home — $0/month (if you have driveway or yard space). You’ll want a quality cover ($300-$600) but that’s a one-time cost. This is the cheapest option by far and the most common for boats under 24 feet.
- Outdoor dry storage — $75-$200/month. The boat sits on its trailer in a fenced lot. Affordable but no protection from weather.
- Covered or indoor rack storage — $150-$400/month. Better protection, and some facilities offer launch-and-retrieve service so you don’t need a tow vehicle.
- Wet slip (marina) — $200-$800+/month. Pricing depends heavily on location. A slip for a 22-foot boat might cost $200/month at an inland lake marina but $500-$700/month in South Florida, San Diego, or the Chesapeake Bay.
Regional examples for a 22-foot boat:
- Lake of the Ozarks, MO: wet slip $175-$300/month
- Tampa Bay, FL: wet slip $350-$500/month
- Fort Lauderdale, FL: wet slip $500-$700/month
- Lake Lanier, GA: covered dock $150-$250/month
- Outer Banks, NC: wet slip $300-$450/month
If you can trailer your boat and keep it at home, you’ll save $2,000-$8,000 per year compared to a marina slip. For many boat owners, this is the single biggest factor in keeping monthly costs manageable.
4. Fuel
Fuel costs depend on three things: engine size, how often you run the boat, and how hard you run it. Here’s a realistic breakdown:
Fuel Burn Rates by Engine Size
| Engine HP | Cruise GPH | WOT GPH |
|---|---|---|
| 75 HP | 4-5 | 7-8 |
| 115 HP | 5-7 | 9-12 |
| 150 HP | 7-9 | 12-16 |
| 200 HP | 8-11 | 15-20 |
| 250 HP | 10-14 | 18-24 |
| Twin 150 HP | 14-18 | 24-32 |
Now assume you boat 12-20 times per season (once or twice a month from April to October in northern climates, year-round in the South), with each trip averaging 3-4 hours of runtime at mixed speeds:
| Scenario | Hours/Season | GPH (avg) | Gallons/Season | Cost at $4.50/gal | Monthly (12 mo) |
|---|---|---|---|---|---|
| Light use, small engine | 40 hrs | 5 | 200 | $900 | $75 |
| Moderate use, mid engine | 60 hrs | 8 | 480 | $2,160 | $180 |
| Heavy use, large engine | 100 hrs | 12 | 1,200 | $5,400 | $450 |
| Heavy use, twin engines | 100 hrs | 16 | 1,600 | $7,200 | $600 |
Most recreational boaters fall in the moderate range: roughly $100-$250/month when annualized. Freshwater lake boaters with smaller engines tend to be at the low end. Offshore anglers running 30+ miles to the fishing grounds and back will be much higher.
5. Maintenance
Boat maintenance is not optional. Deferred maintenance leads to engine failure, hull damage, and expensive emergency repairs. Budget for these recurring items:
Annual Maintenance Costs by Boat Size
| Item | 18 ft | 22 ft | 26 ft | 30 ft+ |
|---|---|---|---|---|
| Engine oil and filter | $75-$100 | $80-$120 | $100-$150 | $150-$250 |
| Lower unit service | $75-$100 | $80-$120 | $100-$140 | $120-$200 |
| Impeller (every 2-3 yr) | $60-$90 | $75-$120 | $100-$150 | $130-$200 |
| Zinc anodes (saltwater) | $40-$60 | $50-$80 | $60-$100 | $80-$150 |
| Battery replacement (every 3 yr) | $100-$150 | $150-$250 | $200-$350 | $300-$500 |
| Hull cleaning/wax | $100-$200 | $150-$300 | $200-$400 | $300-$600 |
| Misc parts and touch-up | $100-$200 | $150-$300 | $200-$400 | $300-$600 |
| Annual Total | $500-$900 | $700-$1,300 | $950-$1,700 | $1,400-$2,500 |
| Monthly | $42-$75 | $58-$108 | $79-$142 | $117-$208 |
These are routine costs. Budget a separate emergency/repair fund of $500-$1,000/year for the unexpected: a prop strike, a dead battery, a failed bilge pump, or a gel coat repair. On older boats, increase that reserve.

6. Registration, Taxes, and Fees
Every state requires boat registration, but costs vary widely:
- Registration fees: $25-$300/year depending on the state and boat size. Florida charges around $30-$85. Texas ranges from $32-$150. States like California and New York can run $100-$300+.
- Personal property tax: Some states (Virginia, Connecticut, others) levy annual personal property tax on boats, which can add $200-$1,000+ per year depending on boat value.
- Sales/use tax: This is a one-time cost at purchase, not monthly, but it affects your total financing amount. Rates range from 0% (Oregon, Montana) to 8-10% (California, Tennessee).
Monthly impact: typically $5-$50/month depending on your state.
7. Winterization (Seasonal Climates)
If you’re in a region with freezing winters, winterization is a non-negotiable annual expense. Water left in the engine, lines, or plumbing will freeze and crack components.
| Service | Cost |
|---|---|
| Engine fogging and fuel stabilization | $100-$200 |
| Lower unit fluid change | $50-$100 |
| Cooling system flush and antifreeze | $50-$100 |
| Battery removal and trickle charge | $25-$50 |
| Shrink wrap | $10-$15 per foot ($180-$450 for 18-30 ft) |
| Total | $300-$800 |
Many marinas offer all-inclusive winterization packages for $400-$700 depending on boat size. Annualized, that adds $25-$65/month to your costs.
If you boat in Florida, the Gulf Coast, or Southern California, you can skip winterization entirely — one of the significant cost advantages of boating in warm climates.
Total Monthly Cost by Boat Size
Here’s the full picture — every cost category combined, assuming a financed purchase with 15% down, 8% APR, 12-year term. Storage assumes a mix of trailer-at-home (small boats) and marina/rack storage (larger boats). Fuel assumes moderate use (50-70 hours/season).

How to Cut Your Monthly Boat Costs
If those numbers feel high, there are concrete ways to bring them down:
Buy used in the $20K-$40K range
The single biggest lever you have is purchase price. A 3-5 year old boat that originally sold for $55,000 might be available for $32,000-$38,000 today. That cuts your loan payment by 30-40% and reduces insurance costs proportionally. The boat still has years of life ahead of it, and the steepest depreciation has already happened.
FindABoat has thousands of used boats from verified dealers in the $20K-$40K range. Most come with engine service records and can be surveyed before purchase.
Trailer and store at home
Switching from a $400/month marina slip to trailer storage at home saves $4,800/year — or $400/month. For boats under 24 feet, this is the most practical way to keep costs down. You’ll need a suitable tow vehicle and somewhere to park, but the savings are enormous.
Reduce engine size
Over-engining is one of the most common mistakes in boating. A 22-foot center console runs perfectly well with a 150 HP outboard for cruising, fishing, and tubing. Stepping up to 200 HP adds $3,000-$6,000 to the purchase price and increases fuel costs by 15-25%. Unless you’re running offshore in rough conditions, the smaller engine does the job at lower cost.
Buy in the off-season
Dealers are most motivated to negotiate from October through February. Boat show season (January-March) also produces competitive pricing as dealers compete for floor traffic. You can save 8-15% off MSRP by timing your purchase right. See our guide on the best time to buy a boat for more detail.
Do your own maintenance
Engine oil changes, impeller swaps, and basic winterization are all within reach of a moderately handy boat owner. YouTube walkthroughs exist for virtually every engine model. Doing your own maintenance can save $300-$600 per year compared to paying a marina or mechanic.
Frequently Asked Questions
Is it cheaper to own a boat or rent one?
At 20+ outings per year, owning is almost always cheaper per trip. A half-day pontoon rental runs $300-$600 in most markets. If you own a pontoon with a total monthly cost of $600, your cost per outing at 20 trips/year is about $360 — and it drops further the more you use the boat. The breakeven point is typically 12-15 uses per year, depending on boat size and rental rates in your area.
What’s the cheapest type of boat to own?
Aluminum fishing boats (16-18 feet) with a single outboard in the 40-90 HP range are the least expensive to buy, insure, fuel, and maintain. A used Tracker or Lund in the $8,000-$15,000 range can bring total monthly ownership costs under $200.
Do boat costs go down over time?
Yes, once the loan is paid off. A paid-off boat typically costs $200-$500/month in ongoing expenses (storage, fuel, maintenance, insurance). That’s why many experienced boaters buy used with a shorter loan term — they’re optimizing for the long-term cost of ownership, not the monthly payment.
Does the purchase price include everything?
No. Budget for sales tax (varies by state), registration, a pre-purchase marine survey ($15-$25/foot), delivery or transport costs, and any immediate upgrades (electronics, cover, safety gear). These can add 8-15% on top of the sticker price.
The Bottom Line
A reasonable monthly budget for boat ownership in 2026:
| Boat Size | Budget Monthly Range |
|---|---|
| 18 ft (entry-level) | $400-$700 |
| 22 ft (mid-range) | $700-$1,300 |
| 26 ft (larger) | $1,100-$2,200 |
| 30 ft+ (premium) | $1,900-$4,300 |
The key to keeping costs manageable: buy a used boat in the sweet spot ($20K-$50K), store it at home if possible, right-size your engine, and maintain it yourself where you can. Boating doesn’t have to break the bank — it just requires planning.
