The Mathematics of Credit Card Compound Interest
Credit card issuers calculate daily finance charges using the Average Daily Balance method:
Daily Periodic Rate = Annual Percentage Rate (APR) / 365
Because interest compounds daily, minimum payments barely erode the principal balance during the first several years. Committing to a constant fixed monthly payment accelerates principal reduction rapidly through an inverse compounding curve.
