What it means
Under a reinvestment plan the cash dividend never reaches the investor's bank account. It is applied to the purchase of additional shares, often including fractional shares, at the market price on or around the payment date.
This matters because most of the long-run return from dividend-paying shares comes from reinvestment rather than from the dividends themselves. Each reinvested payment buys shares that then earn their own dividends, so the number of shares owned grows on a compounding basis rather than a straight line.
Company-operated plans sometimes add a sweetener, offering shares at a small discount to the market price and charging no dealing commission. Broker-operated plans rarely offer a discount but are easier to set up, cover a wide range of shares and can usually be switched on or off with a single setting.
There is an important tax point that surprises people. In most jurisdictions a reinvested dividend is still taxable income in the year it is declared, even though the investor never saw the cash, so a taxable account holder may owe tax with no corresponding cash inflow to pay it.
Record keeping is the other practical burden. Every reinvestment creates a new purchase at a new price, so the cost base of the holding is built from dozens of small lots, and an investor who has not tracked them properly will overstate the eventual capital gain on sale.
Reinvestment is not automatically right for everyone. An investor who needs income now, or who already holds far too much of one company, is better served taking the cash and deciding deliberately where it should go.
A plan of this kind is a convenience, not a substitute for thinking about asset allocation.
In practice
Real-world examples.
Example
A schoolteacher building a retirement pot switches on reinvestment across her whole portfolio at age thirty. Over the following decades the share count roughly doubles from reinvested dividends alone, which she treats as an automatic savings habit she never has to think about.
Example
A retiree does the opposite and turns reinvestment off at sixty-five, directing dividends into a cash account to cover living costs. The holding stops growing but the income becomes spendable, which is what he now needs.
Example
A listed water company offers a company-operated plan at a 3% discount to market price to encourage retail holders to stay invested. Around 40% of its small shareholders enrol, which reduces the cash the company has to pay out each quarter.
Think of it
“DRIP is the abbreviation for dividend reinvestment plan-dividends automatically buy shares.
Formula
Calculation
Formula: Shares purchased = Dividend received / Reinvestment price per share. New holding = Previous shares + Shares purchased.
Worked example. An investor holds 1,000 shares in a utility that pays a quarterly dividend of $0.75 per share, so the first payment is 1,000 x $0.75 = $750. With the share price at $60.00, the plan buys $750 / $60.00 = 12.5 shares, taking the holding to 1,012.5 shares. The next quarter the same $0.75 per share is paid on 1,012.5 shares, giving 1,012.5 x $0.75 = $759.38. At a price of $62.50 that buys $759.38 / $62.50 = 12.15 shares, so the holding reaches 1,024.65 shares. The dividend income has risen by $9.38 a quarter with no new money invested.Case study
Seen in the real world.
This is an illustrative, fictional story. Marlow Grange Foods, an invented listed grocery supplier, had paid a steady quarterly dividend for fifteen years and offered a reinvestment plan through its registrar at a 2% discount. One of its long-standing shareholders, a fictional retired engineer, had held 1,000 shares since the plan launched and had never once taken the cash.
By the fifteenth year his holding had grown to just over 1,900 shares purely through reinvestment and a modest rising dividend, and his quarterly income had almost doubled without a single additional deposit. What he had not done was keep a record of the sixty individual purchase prices.
When he decided to sell part of the holding to fund a house renovation, his accountant had to reconstruct fifteen years of cost base from registrar statements. The illustrative lesson was not that the plan was a bad idea, but that automatic reinvestment still needs a manual filing habit alongside it.
Watch out
Common mistakes.
- Assuming reinvested dividends are not taxable because no cash was received, when in most cases they are taxed as income in the year they are declared.
- Failing to record each reinvestment purchase, which inflates the reported capital gain when the shares are eventually sold.
- Believing a reinvestment plan protects against a falling share price, when it simply buys more of an asset that may keep declining.
Questions
People also ask.
Can I turn a DRIP on and off?
Yes, reinvestment is an instruction rather than a lock-in, and most brokers let you switch it per holding at any time.
Do all DRIPs buy shares at a discount?
No, discounts are a feature of some company-operated plans; broker plans usually reinvest at the prevailing market price with no discount.
Does a DRIP work inside a tax-sheltered account?
It works particularly well there, because the reinvested dividend is not taxed on the way in and the compounding is not interrupted.
