Summer spending has a unique problem: seasonal items get used for only 3-5 months per year, which means their cost per use is inherently higher than things you use year-round. A $500 grill used 20 times over a summer has a very different cost per use than a $500 appliance used daily. And yet, the warm-weather excitement and "summer is short, enjoy it" mentality lead millions of people to overspend on outdoor gear they barely use.
This guide breaks down the real cost per use of the most common summer purchases so you can decide what is worth buying, what to rent, and what to skip entirely.
Above-Ground Pools: The Math Is Brutal (Unless You Commit)
Above-ground pools are one of the most impulse-purchased summer items, and they have some of the worst cost per use numbers in the seasonal category.
Inflatable Pool: $30-80
- Typical lifespan: 1-2 summers (punctures, UV degradation, mold)
- Realistic uses per summer: 15-25 times
- Total uses: 15-50
- Cost per use: $0.60-$5.33
At the low end, a $30 inflatable pool used 50 times over two summers costs $0.60 per use -- acceptable for casual backyard fun. But many inflatable pools get used fewer than 10 times before developing leaks or being abandoned. A $60 pool used 8 times costs $7.50 per use. That is more expensive than a day at the public pool.
Mid-Range Above-Ground Pool (12-15 ft frame): $300-600
- Typical lifespan: 3-5 summers with maintenance
- Setup and maintenance costs: $100-200 per year (chemicals, filters, cover, winterizing)
- Realistic uses per summer: 30-50 times (if the family is committed)
- Total cost over 4 years: $700-1,400
- Total uses over 4 years: 120-200
- Cost per use: $3.50-$11.67
This is where the math gets uncomfortable. Even with heavy use, a mid-range above-ground pool costs $3.50-$12 per swim when you factor in setup, chemicals, and maintenance. A family pool membership often costs $300-500 for the entire summer, and someone else handles the maintenance, cleaning, and water chemistry.
When a Pool Is Worth It
An above-ground pool makes financial sense only if:
- You have multiple family members who will use it frequently (30+ times per summer)
- You maintain it properly to maximize lifespan
- The nearest public pool is far away or expensive
- You factor in the convenience value of not driving to a pool
BBQ Grills: A Wide Range of Value
Grills vary enormously in both price and usage patterns, making them one of the most interesting cost per use calculations.
Budget Charcoal Grill: $40-80
- Lifespan: 2-4 summers
- Charcoal cost per use: $2-5
- Realistic uses per summer: 15-25 times
- Total uses: 30-100
- Equipment cost per use: $0.40-$2.67
- Total cost per use (including charcoal): $2.40-$7.67
Budget charcoal grills offer surprisingly good value if you use them regularly. The main downside is the recurring cost of charcoal and lighter fluid, which adds $2-5 per session.
Mid-Range Gas Grill: $250-500
- Lifespan: 5-8 years
- Propane cost per use: $1-2
- Realistic uses per summer: 20-40 times
- Total uses: 100-320
- Equipment cost per use: $0.78-$5.00
- Total cost per use (including propane): $1.78-$7.00
A mid-range gas grill is one of the better summer investments -- if you grill regularly. The convenience of gas (no charcoal prep, consistent heat, quick startup) means you are more likely to actually use it, which drives down cost per use.
Premium Gas or Pellet Grill: $800-1,500
- Lifespan: 8-15 years
- Fuel cost per use: $1-3
- Realistic uses per summer: 25-50 times
- Total uses: 200-750
- Equipment cost per use: $1.07-$7.50
- Total cost per use (including fuel): $2.07-$10.50
Premium grills can achieve excellent cost per use over their lifespan, but only for dedicated grillers. If you grill 40+ times per summer and the grill lasts a decade, the cost per use is very reasonable. If you are a casual griller who fires it up 10 times a year, a $1,200 grill is an expensive luxury.
The Grill Verdict
| Grill Type | Best For | Worst For |
|---|---|---|
| Budget charcoal ($50) | Occasional grillers, renters | Anyone who grills more than once a week |
| Mid-range gas ($350) | Regular grillers, families | People who grill fewer than 10 times per summer |
| Premium ($1,000+) | Dedicated grillers, entertainers | Casual or infrequent grillers |
Patio Furniture: The Seasonal Penalty
Outdoor furniture carries what you might call the "seasonal penalty" -- it depreciates from weather exposure whether you use it or not. Sun fades fabrics, rain warps wood, and winter storage adds wear.
Budget Patio Set (4 chairs + table): $150-300
- Lifespan: 2-3 summers
- Uses per summer: 30-60 sits (dinner, morning coffee, relaxation)
- Total uses: 60-180
- Cost per use: $0.83-$5.00
Budget patio furniture often looks acceptable the first summer and deteriorates quickly after that. Plastic fades, cheap metal rusts, and thin cushions flatten. The cost per use is acceptable only if you use the set frequently.
Mid-Range Patio Set: $500-1,000
- Lifespan: 5-8 summers with care
- Uses per summer: 40-80
- Total uses: 200-640
- Cost per use: $0.78-$5.00
Mid-range patio furniture hits the sweet spot for most families. Better materials (powder-coated aluminum, woven resin, Sunbrella fabrics) withstand weather better and look good for years. The cost per use drops below $1 with regular use over 5+ years.
Premium Patio Set: $2,000-5,000
- Lifespan: 10-20 years
- Uses per summer: 50-100
- Total uses: 500-2,000
- Cost per use: $1.00-$10.00
Premium outdoor furniture made from teak, high-grade aluminum, or marine-grade materials can last decades. But the cost per use only becomes competitive with mid-range options if you use it very frequently over many years. For most households, the mid-range tier offers the best value.

Other Summer Items: Quick Cost Per Use Calculations
Paddleboard: $300-800
- Uses per summer: 10-20 (realistically)
- Lifespan: 5-8 years with proper storage
- Total uses: 50-160
- Cost per use: $1.88-$16.00
Paddleboard rental typically costs $20-40 per session. If you paddle fewer than 20 times per year, renting is cheaper. If you go 30+ times per year, buying makes sense.
Kayak: $250-600
- Uses per summer: 10-20
- Lifespan: 8-15 years
- Total uses: 80-300
- Cost per use: $0.83-$7.50
Kayaks have better cost per use than paddleboards because they last longer and are more comfortable for extended use, which means you are more likely to actually go out. Storage is the main hidden cost -- if you need to rent storage space, factor that in.
Lawn Mower: $200-500 (push) or $1,500-3,500 (riding)
- Uses per summer: 15-20 mows (roughly weekly)
- Lifespan: 8-15 years
- Total uses: 120-300
- Cost per use: $0.67-$29.17
A push mower at $300 used for 10 years is one of the best cost per use summer items at under $1 per mow. Riding mowers only make cost per use sense for large properties where the alternative (hiring a lawn service at $40-80 per visit) would cost more.
Outdoor Projector Setup: $150-400
- Uses per summer: 5-15 movie nights
- Lifespan: 3-5 years
- Total uses: 15-75
- Cost per use: $2.00-$26.67
Outdoor movie nights are wonderful in theory. In practice, most families do them 5-10 times per summer at most. At $300 for a projector, screen, and speakers, you need consistent use over several years to justify the cost.
Kiddie Splash Pad: $30-60
- Uses per summer: 20-40
- Lifespan: 1-2 summers
- Total uses: 20-80
- Cost per use: $0.38-$3.00
One of the better summer impulse buys for families with young children. Kids use these frequently, they are cheap, and even at the low end of usage they offer decent cost per use.
How to Decide: Buy, Rent, or Skip
Buy If:
- The cost per use over 3+ years is below $2 for frequently used items
- You have proper storage space
- The item replaces an ongoing expense (like grill vs. eating out)
- Multiple family members will use it regularly
Rent If:
- You plan to use the item fewer than 10 times per season
- You are trying the activity for the first time
- Storage is limited or costly
- The rental cost per use is comparable to the ownership cost per use
Skip If:
- You are buying based on a fantasy of how your summer will look rather than how your summers actually go
- The item requires significant maintenance you are unlikely to perform
- You bought a similar item in the past and barely used it
- The cost per use, even with optimistic estimates, is poor
The Bottom Line
Summer gear has a built-in cost per use disadvantage: seasonal items sit unused for 7-8 months of the year. That does not make them bad purchases -- it makes honest usage estimates essential. Before buying any summer item, look back at last summer. How many times did you actually grill? How many times did you sit on the patio? How many days did the kids swim? Base your purchase decisions on your real behavior, not your idealized summer plans. The cost per use never lies.
