The Equation that Exposes Subscriptions

In this video, we explore how calculus can be applied to business to help us determine the true cost of subscription services over a lifetime. With inflation data, an exponential decay curve, and some calculus, we can estimate the future value of subscription costs. Learn about exponential decay and its relevance to subscription services, followed by a detailed explanation of how calculus can be used to find the lifetime cost of a subscription service. We also demonstrate how to use average monthly inflation data as the rate of decay in the integral, which provides an adequate estimation of the future value of subscription costs. Stay tuned to learn the true cost of popular subscription services such as Netflix, Spotify, and Amazon Prime. You may be spending more than you think!.
