Enter the price and how many soft drinks you have a week to see the yearly and ten-year cost.
Then compare it with the invested alternative to weigh the habit against the long run.
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.
