About this habit
Impulse online shopping is the subscription nobody signed up for. One-click checkout and same-day delivery make small unplanned purchases almost invisible, and a just-sixty-dollars-this-month habit repeats twelve times a year and then keeps going. Modeled over five, ten and twenty years, those scattered buys add up to a figure large enough to reframe how you think about the cart. This page lets you enter your realistic monthly impulse spend and projects the cumulative total, with an inflation-adjusted option. A short waiting-period rule, leaving items in the cart for a day or two, tends to cut the number meaningfully. And because the spending is so easy to lose track of, the cancel-vs-invest comparison is often the most surprising view: the same money, invested steadily instead, builds a balance that makes the impulse purchases feel a lot more expensive in hindsight.
