How APY interacts with compounding frequency
Most HYSAs disclose an APY, which already includes the effect of compounding. For $10,000 at an unchanged 4.5% APY over five years, converting that APY for daily, monthly or annual periods produces approximately the same no-deposit result: $12,462.
Enter the disclosed APY once and do not compound it again as if it were a nominal APR. Provider crediting schedules, rate changes and balance tiers still determine the actual result.
