About this habit
Bottled water is the clearest example of frequency cost. Each bottle is cheap, a dollar or two, which is exactly why nobody tracks it. Buy one a day, though, and you are spending hundreds of dollars a year on something that flows nearly free from a tap. Over a decade the total is enough for a high-end laptop or a weekend trip, all in single-dollar increments you never noticed. A reusable bottle and a basic filter usually pay for themselves within weeks and then keep paying you back. This page lets you model your own bottled-water habit at whatever price and frequency matches your routine, see the cumulative total over time, and compare it against investing the same money. It is a small swap with an outsized long-term number, the kind of thing that is easy to fix once you can actually see it.
