Dividend DRIP Calculator

How to use this dividend DRIP calculator

Enter your initial investment, your starting dividend yield, how fast dividends grow each year, how fast the stock price appreciates, and your time horizon. The calculator reinvests dividends annually and shows you the compounded result: final portfolio value, projected annual dividend income, and total dividends collected over the period.

Use the advanced options to add a monthly contribution or apply a dividend tax rate. Set the tax rate to 0% to model a Roth IRA or 401(k) where dividends compound tax-free. Use 15% to 20% to model a taxable brokerage account with qualified dividends.

What is a DRIP and why does it work?

A Dividend Reinvestment Plan (DRIP) uses each dividend payment to buy additional shares of the same investment instead of paying out cash. Those new shares generate their own dividends the following period, which are reinvested again. This is compounding applied to income: not just your returns growing on themselves, but your share count growing on itself.

Take the calculator's own defaults: $10,000 invested, a 3.5% yield, dividends growing 5% a year, the share price growing 7% a year, twenty years, no tax and nothing added along the way. Reinvested, that becomes $69,114, of which $16,466 is dividends that bought more shares. Take the dividends in cash instead and the holding is worth $38,697 with $11,573 collected along the way, so $50,270 in total. The gap is $18,844, and all of it comes from dividends that were themselves earning dividends.

The longer the time horizon, the wider the gap between DRIP and no-DRIP outcomes. Reinvestment does most of its work in the final years of a long holding period.

Reinvest or take the cash?

Reinvesting wins on total value, and the margin widens the longer the money is left alone. The figures below come from the calculator above, on its default settings: $10,000 invested, a 3.5% starting yield, dividends growing 5% a year, the share price growing 7% a year, no tax and no monthly contributions. The cash column counts both what the holding is worth and every dividend taken out of it.

At ten years reinvesting is ahead by about 12%. At thirty it is ahead by 70%. That shape is the whole argument for leaving a dividend portfolio alone, and it is also why the choice matters most early: the shares bought in year three are the ones still paying in year thirty.

What the tax field does, and what it cannot know

The tax rate you enter is applied to each dividend before it buys new shares, which is how a taxable account behaves: the broker withholds, and only what is left is reinvested. Set it to zero for an account where dividends are not taxed as they arrive, such as a Roth IRA in the United States or an ISA in the United Kingdom.

What it cannot do is model your jurisdiction. Withholding on foreign dividends, allowances, and the treatment of accumulating funds all vary by country and by year, and none of that is knowable from a single percentage. The figure is a straight haircut on each payment, useful for comparing scenarios and not a substitute for advice on your own return.

Dividend yield vs dividend growth rate

These are two separate inputs that are often confused. Dividend yield is the current annual payout as a percentage of the share price: a $50 stock paying $1.75 per year has a 3.5% yield. Dividend growth rate is how much that $1.75 increases per year, independent of the share price.

A company with a modest 2% yield but a consistent 8% annual dividend growth rate will pay more per share within ten years than one starting at 5% yield but growing dividends by only 2% per year. Over long periods, dividend growth often matters more than the starting yield.

Dividend Aristocrats, a group of S&P 500 companies that have raised dividends for 25 or more consecutive years, have historically averaged dividend growth rates between 5% and 8% per year. This calculator lets you test any combination to see which profile fits your goals best.
