grow your income with DRIP.

Field guide

Dividends, DRIP, and the power of compounding.

A dividend is a cash payment a company distributes to its shareholders, typically every quarter, from its profits. Dividend investing is one of the oldest and most straightforward paths to passive income: you buy shares, the company pays you a slice of its earnings, and you decide whether to spend that cash or put it back to work buying more shares.

What is dividend yield?

Dividend yield is the annual dividend payment expressed as a percentage of the current stock price. If a stock trades at $50 and pays $2 per share each year, its yield is 4%. Yield tells you the immediate cash return on your investment, ignoring any price appreciation.

Yields vary widely by sector. Utilities and real estate investment trusts (REITs) often yield 4–7%. Large consumer staples companies commonly yield 2–4%. High-growth technology companies frequently pay no dividend at all, preferring to reinvest profits.

What is a DRIP?

A Dividend Reinvestment Plan (DRIP) automatically uses each dividend payment to purchase additional shares of the same stock instead of paying you cash. Many brokerages and companies offer DRIP at no commission, and some even allow fractional shares, meaning every cent of every dividend goes back into buying stock.

The mechanics are simple: if you own 200 shares of a $50 stock paying a 4% annual yield, your quarterly dividend is $100. With DRIP enabled, those $100 buy 2 more shares at $50. Next quarter you earn dividends on 202 shares instead of 200. The quarter after, on 204+. Over 20 years, this compounding effect is dramatic.

The math behind the comparison

This calculator models two parallel scenarios for the same starting investment, stock price, and dividend yield:

• With DRIP: each dividend payment (monthly, quarterly, or annually) is reinvested by purchasing additional shares at the current stock price. The dividend-per-share figure grows at your chosen dividend growth rate each year. Because you now own more shares, the next dividend payment is larger, which buys more shares — a true compounding loop.
• Without DRIP: dividends are paid as cash and not reinvested. Your share count never grows from dividends. You still benefit from stock price appreciation and the rising dividend-per- share (if dividend growth rate > 0%), but you forgo the exponential share accumulation that DRIP creates.

The stock price growth rate you enter is applied to both scenarios equally — the only variable is whether dividends are reinvested. This isolates the pure impact of DRIP on your terminal portfolio value.

Why payment frequency matters

Reinvesting monthly rather than quarterly or annually means your new shares start compounding slightly sooner. The effect is modest compared to yield and growth rate, but over decades it adds up. At a 4% yield and 7% stock growth over 30 years, switching from annual to monthly DRIP typically adds an extra 1–2% to the final portfolio. This calculator lets you compare all three frequencies side by side.

Dividend growth rate: the hidden accelerator

Companies that consistently raise their dividends are known as Dividend Aristocrats (S&P 500 companies that have raised their dividend for 25+ consecutive years) or Dividend Kings (50+ years). A stock that starts with a 3% yield and raises it 7% per year doubles its dividend roughly every ten years. That means your yield-on-cost — the yield relative to what you originally paid — rises dramatically over time, even if the stock price also rises.

FIRE and dividend investing

The Financial Independence, Retire Early (FIRE) community often uses dividend income as a target for replacing earned income. The goal is to accumulate enough dividend-paying assets that passive income covers living expenses. The appeal is clear: unlike selling shares, dividends can be collected without shrinking your portfolio principal. DRIP accelerates the accumulation phase, while switching off DRIP at retirement converts the compounding engine into a reliable income stream.

Tips for using this calculator

• Be conservative with growth rates. Long-run US stock market returns average around 7% after inflation. Using 10% or higher will produce impressive numbers that are hard to replicate in practice.
• Dividend growth rate of 5–7% is consistent with historical Dividend Aristocrat averages. A 0% growth rate models a fixed-income-style holding.
• The stock price growth rate and dividend yield interact. If a stock's price rises 10% per year but dividends stay fixed, the yield falls each year. This model keeps dividend-per- share growing independently of price, which better reflects how real dividend-growth stocks behave.
• Taxes are not included. In taxable accounts, qualified dividends are taxed at long-term capital gains rates (0%, 15%, or 20% depending on income). Even with DRIP, you typically owe tax on dividends in the year they are paid. In tax-advantaged accounts (IRA, 401k), DRIP works without immediate tax drag.
