Compound Interest
Project how savings grow over time · estimate the balance after compounding and build intuition for exponential growth
About Compound Interest
Compound Interest is a financial number-sense game · you estimate how a sum grows once interest compounds over time, building intuition for exponential growth.
How a round works. Read the principal, rate, and time, then pick the closest projected balance. The reveal shows the exact figure so you calibrate your mental model.
Part of Finance Lab. Compound Interest is both its own game and a tab inside the Finance Lab hub, so you can play it on its own or alongside the related games.
Still in beta. Compound Interest was just broken out into its own game, so you will find it in the Beta section of the library while its standalone landing is finished.
Part of PlayMemorize, a passion project from Christoffer De Geer. It runs entirely in your browser.
