Enter the price of a pod, disposable or bottle and how many you go through a week. We turn it into a yearly and ten-year total.
Then we show what investing that money instead could grow to — a simple way to weigh the habit against the alternative.
How it's worked out
Yearly cost = price × times per week × 52. The “if invested” figures assume you put the same amount in each year and it grows at the rate you set (default 7%) — an ordinary annuity. They're estimates to show scale, not guaranteed returns.
