Separate Monthly Principal and After-Tax Interest
Regular savings deposits earn interest over staggered deposit periods, so the result differs from a fixed deposit with the same principal total.
- Principal is monthly deposit multiplied by term.
- Earlier deposits earn interest for more months than later deposits.
- Tax mode changes the after-tax maturity amount.
