At roughly 4.99 a month, Amazon Prime is 60 a year, 599 over a decade and 1,198 over twenty years, at today's price and before increases. Here is the receipt and what the same money is in real things.
Maybe. That is not the point of the page. The point is that delivery and streaming subscriptions are priced to feel small per month, and 4.99 feels small. 599 over a decade does not. Both numbers are the same purchase; only the framing changes. If you use Amazon Prime every week, the decade price may be one of the best deals you have. If you opened it twice last month, you now know what "I'll cancel it eventually" costs per year: 60.
Today's price, no increases, no annual-plan discount, no shared family plan, no free months. Real ten-year cost is usually higher because prices rise; this is the floor. Currency is left generic on purpose: the figures are close enough in EUR, USD and GBP to use as they are, and you can edit any price in the full calculator.
Cancelling Amazon Prime for six months a year (most people binge in bursts) saves about 30 a year and 299 over ten years. Downgrading to a cheaper tier, sharing legitimately with a household, or rotating between services are all cheaper than the default of paying every month forever.
