What are advantages of using annual equivalent rate as a mean for evaluating saving products?

The Annual Equivalent Rate (AER) provides a standardized way to compare different savings products by expressing interest rates on an annual basis, regardless of compounding frequency. This allows consumers to easily assess and compare the true returns of various accounts. Additionally, AER accounts for the effects of compounding, giving a more accurate picture of potential earnings over time. Overall, using AER helps consumers make informed decisions about where to allocate their savings.
