The idea

Small spends, big numbers

A daily expense looks trivial, but multiplied over years it becomes a number that stings. This tool projects what a habit adds up to — smoking, food delivery, the daily coffee — and compares it to what it could have returned if invested.

The point isn't guilt: it's to size the opportunity cost, the money that could have grown instead of disappearing.

FAQ

What you're wondering

Yes. We offer examples (cigarettes, food delivery, coffee), but you can enter any daily spend.
