The True Cost of Bottled Water

Bottled water is one of the most expensive ways to stay hydrated. A typical 16-ounce bottle costs 1 to 2 dollars, which works out to about 5 to 10 dollars per gallon — roughly 1,000 times the cost of tap water. For a family of two buying 14 bottles per week, that adds up to over 2,000 dollars per year.

Cost comparison (per gallon):
Tap water: ~$0.005
Filtered water (pitcher): ~$0.10-0.30
Bottled water: ~$5-10

Environmental Impact

  • Producing a year's worth of bottled water for one person uses ~17 million barrels of oil globally.
  • Only 20-30% of plastic water bottles are recycled.
  • Plastic bottles take 400-1,000 years to decompose.
  • Many bottled waters are simply packaged tap water.

A reusable stainless steel bottle and a quality water filter can save you thousands of dollars over 5-10 years while dramatically reducing plastic waste. See our guides to water quality and water filters for choosing a filter.
