Dividend Calculator
Estimate your annual, quarterly, and monthly dividend income — and project how reinvesting dividends (DRIP) grows your portfolio over time.
Understanding the Dividend Calculator
This tool estimates the income a dividend-paying portfolio generates and projects how reinvesting those dividends (a DRIP, or dividend reinvestment plan) can compound holdings over time. It is built for income-focused and long-term investors who want to see annual payouts, yield on cost, and the snowball effect of buying more shares with each distribution. You can model a one-time investment plus a chosen dividend yield, growth rate, and reinvestment setting. Outputs are educational estimates and assume the inputs hold steady; real dividends can be cut, raised, or suspended.
How it works
Enter your investment amount (or share count and price), the annual dividend yield, expected annual dividend growth, and the number of years. With reinvestment on, each payout buys additional shares, which then earn dividends themselves, compounding the base. The calculator multiplies your balance by the yield to find annual income, optionally grows the per-share dividend each year, and rolls payouts back into the position when DRIP is enabled. Read the results as projected annual income and ending balance. It assumes a constant yield and reinvestment at the same price unless you specify share-price growth.
Worked example
Invest $20,000 in stocks yielding 4% with no growth. Year one income is 20,000 x 0.04 = $800. With DRIP on, that $800 buys more shares, so year two earns on $20,800, paying about $832. Over 10 years of reinvesting at a steady 4% yield, the position compounds to roughly $29,600, producing about $1,184 in annual dividends by the final year, versus a flat $800 a year without reinvestment.
Tips & common mistakes
- Yield on cost rises over time if a company keeps raising its dividend, even when current yield looks flat.
- Very high yields (above 8 to 10%) can signal risk of a dividend cut, not a bargain.
- Reinvestment compounds only if the company sustains payouts; model a haircut to stress-test.
- Taxes and brokerage fees on dividends reduce real reinvestment; this estimate ignores them.
- A constant-yield assumption oversimplifies; share prices and payout ratios change in practice.

Frequently Asked Questions
How is dividend income calculated?
Annual income = investment amount × dividend yield. We then divide by 4 for quarterly and 12 for monthly estimates.
What is DRIP?
A Dividend Reinvestment Plan automatically uses your dividends to buy more shares, so your income compounds over time. Toggle "Reinvest dividends" to model this growth.
Are dividends guaranteed?
No. Companies can cut or suspend dividends, and yields change with share price. This tool shows estimates based on a fixed yield you enter.
