A backyard swimming pool is one of the most expensive non-essential things you can add to a home. The installation is just the beginning — between chemicals, energy, repairs, insurance, and eventual resurfacing, a pool costs $3,000-$6,000+ per year to maintain. Over 20 years, the total ownership cost reaches $120,000-$220,000. Here’s every dollar, so you can decide if the cannonballs are worth it.

Common Mistakes
Mistake
Why It’s Costly
Underestimating ongoing costs
Maintenance is $4,000-$8,000/year — forever
Choosing cheapest installer
Poor construction = $10,000-$30,000 in early repairs
Not budgeting for a heater
An unheated pool in most of the US is usable only 3-5 months
