What Is DRIP? Dividend Reinvestment Explained
The short answer
DRIP — a dividend reinvestment plan — automatically uses your dividends to buy more shares instead of paying them to you as cash. Those extra shares then earn dividends themselves, so your income can grow without you adding new money. Most brokers offer DRIP as a free account setting, and many allow fractional shares so every cent is invested.
The snowball effect
In the early years the effect looks trivial: a small dividend buys a fraction of a share. The compounding happens because the share count, not just the price, grows every payment. Over decades, reinvested dividends can account for a large share of a portfolio's total value — which is why our DRIP calculator shows the share count year by year, not just the final value.
The tax catch
In many countries, including the US, reinvested dividends are taxed in the year they are paid even though you never received cash. Non-US investors may also have withholding tax deducted before reinvestment, so the amount actually reinvested is the net figure. Neither changes whether DRIP is worthwhile, but both change the honest projection.
When not to reinvest
If you are using dividends to pay living costs, reinvestment defeats the purpose. Some investors also pause DRIP when they plan to rebalance into other assets, preferring to direct cash manually. DRIP is a tool for the accumulation phase, not a rule for life.
