Small daily spending never feels like much. This calculator turns a daily habit — an iced coffee, an energy drink, a takeaway lunch, a rideshare — into what it could become if the same money were invested at an 8% average yearly return.
$5 a day is about $152 a month. Invested consistently from your teens, that is the raw material of a six-figure balance by middle age. The point isn't to never buy coffee — it's to see that tiny repeated amounts are what actually build wealth, and that teenagers have more time than almost anyone.
