Spending Leak Detector

Spending Leak Calculator

The Spending Leak Detector puts a real price on the small recurring habit you barely notice. You enter what you spend each time, how often it happens, an investment return, and a time horizon, and it returns what that habit costs you over the years if the same dollars were invested instead. Use it when a daily or weekly expense feels harmless and you want to see its true long-term cost. A modest amount repeated week after week and given time to compound grows into a number large enough to change your mind, or to confirm the spending is worth it to you. Either way you decide with the full picture in front of you.
