Why is APY significant for investors?

APY, or Annual Percentage Yield, is significant for investors because it accurately reflects the true return on an investment after accounting for the effects of compounding interest. When comparing various investment options or savings accounts, APY provides a clearer picture of potential earnings than nominal interest rates, as it incorporates how often interest is applied to the principal balance. This allows investors to better assess the profitability of different financial products over a year, making it easier to make informed decisions regarding where to allocate their funds. By understanding APY, investors can strategically plan for their financial goals, as it highlights the impact of compounding on overall returns.
