Compounding Frequency: Why Monthly Beats Annual on the Same Rate

Two accounts quoting the same headline rate do not pay the same money if they compound on different schedules. Interest credited monthly starts earning interest itself eleven months earlier than interest credited once a year, so the effective annual yield sits slightly above the nominal rate. The gap widens with the rate and with the time horizon: it is negligible over one year on a small balance, and meaningful over a decade on a retirement account. When comparing products, read the effective annual rate rather than the nominal one, and check whether contributions are added at the start or the end of each period — start-of-period deposits earn one extra period of growth each time.
