APY vs headline rate: why 4.9% needs context

A large number in a headline can look simple, but the label next to that number matters. APY attempts to express annualized yield with compounding, while a plain interest rate may describe only one part of the calculation.

When reading a 4.9% message, look for whether it says APY, whether the APY is variable, and whether the calculation assumes money stays in place for a full year.

Read the sentence around the rate

The safest habit is to read the full sentence, footnote, and eligibility block before comparing two options.
