INVESTING BASICS
Dividend reinvestment: how DRIPs add shares over time
When a company pays a dividend, you can receive the cash or use it to buy more shares. A dividend reinvestment plan—often called a DRIP—models the second option. It can be useful for exploring long-term scenarios, but it is not a promise of future income or returns.
The basic idea
A dividend is a payment a company may make to shareholders. If it is reinvested, the payment purchases additional shares at the assumed share price. Those new shares may then be eligible for later dividends. This is the compounding effect a DRIP calculator is illustrating.
Simplified reinvestment math
New shares = dividend cash received ÷ assumed share price
For an estimate, you need a starting investment, an annual dividend per share, a payout frequency, an assumed share-price change, and a time period. Real-world dividends and stock prices can change at any time.
A simplified quarterly example
Suppose you own 100 shares, each company payment is $0.50 per share, and the stock price is assumed to be $50.
At the next payment, the estimate starts with 101 shares instead of 100. A calculator repeats this process according to the selected payout frequency, alongside any assumptions you set for contribution amounts, taxes, dividend growth, and share-price growth.
Taking cash versus reinvesting dividends
Reinvestment means the dividend stays invested and buys more shares. Taking cash means the payout is kept outside the investment. Neither is automatically better: the appropriate choice depends on your goals, taxes, account type, spending needs, and the investments available to you.
In a taxable account, dividends can create a tax obligation even when they are automatically reinvested. The tax settings in a calculator are simplified illustrations, not tax advice.
What this kind of estimate cannot know
Companies may reduce, suspend, or eliminate dividends. Share prices may fall. Payout dates, tax treatment, fractional-share availability, fees, and reinvestment prices differ by broker and account. Use projections to compare assumptions—not as a forecast.
