How much is bottled water actually costing you?

Slide in what your household drinks, what you pay, and which RO tier you'd install. The math updates live. No email gate, no "schedule a consultation to see your savings" trick.

Bottled gallons per week

gal

Household average for a family of four is roughly 5–15 gallons per week if bottled is the main drinking source.

Cost per gallon

$/gal

Default is the US retail average ($1.22/gal). Walmart and Costco multipacks usually run cheaper; convenience-store single bottles run much higher. Use the number on your last receipt.

System tier

Based on your inputs, the projection is

Bottled water costs you: $52.87 / month
An RO system pays back in: 42.6 months
5-year projected savings: $777

5-year total cost, side by side

Bottled water$3,172

RO system (Water Filtration 1 under-sink RO)$2,395

Includes the one-time install plus 5 years of filter replacement at $100/year. Annualized RO cost: $479.

On the non-financial side: at this rate you'd avoid roughly 19,500 single-serve 16oz plastic bottles over 5 years. Worth knowing — not the only reason to switch.

RO is the right answer for dissolved solids, PFAS, lead, and bottled-water replacement. It is not the right answer for hard water alone — a softener does that job better and cheaper. A free test tells you which one (or both) your home actually needs.

Where the default numbers come from

$1.22/gal bottled water: Beverage Marketing Corporation, US Bottled Water Statistics 2023, summarized at bottledwater.org. Your actual price will differ by package size and retailer.
$1,895 RO install: Water Filtration 1’s confirmed price for a professionally installed under-sink reverse-osmosis system — see the under-sink RO page. This is the price we quote, not an estimate.
$80–$150/yr filter replacement (national estimate, not a WF1 quote): Family Handyman RO cost guide. Sediment + carbon yearly; RO membrane every ~2 years.
7.5 bottles/gal: 128 fl oz per US gallon ÷ 16 fl oz per bottle ≈ 8; we use 7.5 to account for 16.9oz half-litre single-serves common in US retail. Disposal context: EPA plastics data.

A few honest caveats

It's a projection, not a promise. The result is just your inputs, multiplied out. If your bottled spend or filter prices change, so does the answer.
RO is for drinking water. It does not soften hard water for showers, dishwashers, or tankless heaters. If you have scale on faucets, you probably want a softener too (or instead).
Wells need a test first. If you're on a private well, sediment and iron will kill a standard RO membrane fast. A pre-filter or full pretreatment changes the math. We'll tell you straight if RO isn't the right play for your water.
