Compound Interest Calculator — Annual Compounding
Annual compounding credits interest just once per year, so a full twelve months pass before any growth begins earning on itself. With one crediting period the effective annual yield equals the nominal rate exactly — 7% nominal stays 7% APY, with no frequency boost. This page pre-fills a single compounding period per year, which is the slower-growth baseline that monthly or daily crediting is measured against.
