Open tool →What's in Silly Money Math?
Silly Money Math runs real numbers through ridiculous units. See your daily scrolling priced in pizzas, your coffee habit compared with your rent or your subscriptions turned into a guilt meter.
Under the jokes is simple arithmetic you can check: minutes × value × days, prices × frequency. Seeing a habit as a yearly number (or 400 pizzas) makes it easier to decide whether it is worth it — or to happily keep it.
