How This DRIP Calculator Works

Each year, the shares pay a dividend equal to the yield times the current share price. With reinvestment, that cash buys new shares at the current price; without it, the cash is kept and the share count stays the same. In both cases the share price grows by the annual growth rate each year.

Worked example: 100 shares at $50 ($5,000), 4% dividend yield, 8% annual price growth, 10 years. With reinvestment you end with 148.02 shares at $107.95 = $15,978.68. Without it you keep 100 shares worth $10,794.62 plus $2,897.31 of cash dividends = $13,691.94. The DRIP advantage is $2,286.74.

Practical tips

The advantage grows with time.

Over 10 years the DRIP edge is about 17% here; over 30 years it roughly doubles the ending value. Reinvestment is a long-game strategy.

Yield and growth both compound.

A high yield with no price growth still compounds through share count; a high growth rate with no yield compounds through price. The combination is the strongest.

Reinvested dividends are still taxed.

In a taxable account, dividends are taxed in the year received — even when reinvested. Hold dividend stocks in a tax-advantaged account where possible.

DRIP does not fix a bad stock.

Reinvesting into a falling company buys more of a falling asset. The model assumes steady growth; check the business, not just the yield.
