Dividend Reinvestment Calculator

A DRIP — a dividend reinvestment plan — automatically uses each dividend to buy more shares instead of paying you cash. Those new shares pay their own dividends, which buy still more shares, so your share count and income compound together. The calculator steps month by month: it grows the share price and the dividend per share on their own schedules, pays a dividend on every payment date based on the shares you hold, and reinvests it into more shares (net of any tax or commission). On the default plan — 10,000 in a 50 stock at a 3% yield, growing 6% a year, with 100 added monthly for 20 years — reinvesting turns 34,000 of money in into about 124,148.

It depends mostly on how much the share price grows, because reinvested dividends buy shares that then appreciate, while cash dividends just sit there. On the default plan, reinvesting ends at about 124,148 versus roughly 100,051 if every dividend were taken as cash and set aside — an extra 24,097 created purely by the snowball of shares buying shares. The longer your horizon and the higher the price growth, the wider that gap becomes; with no price growth at all, a reinvested dividend is worth exactly the cash you gave up, so the advantage shrinks toward zero.

Yield on cost is your current annual dividend income divided by the money you originally put in — not by today's share price. It rises over time for two reasons that compound: the dividend per share keeps growing, and (with a DRIP) you keep owning more shares. On the default plan the stock still yields about 3% on its market price at the end, yet the income — about 3,724 a year — works out to roughly 11% of the 34,000 you invested. That growing yield on cost is the whole appeal of dividend-growth investing: a stake that quietly pays you back a larger and larger share of your original outlay every year.

Dividend tax is taken out of each payment as it is paid, so only the after-tax amount is reinvested or received — which means the tax also shrinks every future dividend that money would have earned. On a 10,000 lump sum with no extra contributions, a 20% dividend tax cuts the 20-year value from about 58,307 to 51,755; only 3,061 of that is tax actually paid, while the full drag, counting the compounding you lose, is about 6,552. The calculator models dividend tax only — it does not apply capital-gains tax on the eventual sale of your shares, so the ending value is a pre-sale figure. Holding dividend stocks in a tax-advantaged account is the simplest way to avoid the drag entirely.

They can, especially for smaller positions. With fractional shares on (the default), every cent of a dividend or contribution is put to work immediately. With whole shares only, a dividend that isn't quite enough to buy a full share leaves the remainder waiting as cash until it can, which slightly slows the compounding — the effect is largest early on, when each dividend is small relative to the share price. A brokerage commission is charged on every purchase, including each reinvestment, so on a stock paying many small dividends a percentage fee quietly skims the snowball. Many brokers now offer commission-free fractional DRIPs, which is the most efficient setup the calculator can model.

No. It assumes a steady dividend yield, a constant dividend growth rate and a constant share-price growth rate, which no real stock delivers — dividends get cut, prices fall in bear markets, and growth rates wander. Treat the projection as a disciplined illustration of how reinvestment compounds under your assumptions, not a forecast. Use it to compare choices you control — reinvesting versus taking cash, a higher- versus lower-growth dividend payer, or the cost of holding in a taxable versus a sheltered account — rather than as a promise of a specific future balance.
