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.
