How Dividend Reinvestment Works

1

Company Pays Dividend

Each quarter or half-year, the company distributes a portion of profits as a dividend β€” typically expressed as a percentage of the share price (the yield).

2

Dividends Buy More Shares

Instead of receiving cash, the DRIP automatically uses each dividend payment to purchase additional shares β€” often without brokerage commission and sometimes at a small discount.

3

Compounding Accelerates Growth

More shares produce more dividends, which buy even more shares. This compounding snowball, combined with price appreciation, can dramatically increase long-term portfolio value.

The Calculation Method

This calculator runs a month-by-month simulation. Each month the portfolio grows by the monthly equivalent of the annual appreciation rate, earns a dividend based on the monthly yield, deducts any tax on the dividend, then adds the net dividend and any additional contribution back to the balance.

  • Monthly appreciation factor: (1 + appreciation% / 100)1/12 − 1
  • Monthly dividend yield: annual yield% / 100 / 12
  • Net dividend: gross dividend × (1 − tax rate / 100)
  • Tax rate of 0% reflects a fully tax-sheltered account (ISA, TFSA, Roth IRA, superannuation)
