What Is Compounding?
Compounding is the process in which an asset’s earnings, from either capital gains or interest, are reinvested to generate additional earnings over time. This exponential growth occurs because the investment will generate earnings from both its initial principal and the accumulated earnings from preceding periods. This principle stands in contrast to linear growth, where only the principal earns interest each period.
