Dividend Reinvestment Calculator — DRIP Growth

Dividend reinvestment is the practice of automatically using cash dividends to purchase additional shares of the same stock or fund, rather than receiving that cash and doing something else with it. Many brokerages and companies offer this as a formal DRIP, or dividend reinvestment plan, but you can achieve the same effect manually by simply buying more shares yourself every time a dividend lands in your account.

The reason a dividend compounding calculator is worth using rather than eyeballing the math is that reinvestment creates a snowball effect that is easy to underestimate. Your first dividend buys a few extra shares. Those extra shares then earn their own dividend the following year, which buys still more shares, which earn dividends of their own, and so on. Over a decade or two, this compounding can meaningfully outgrow simply spending each dividend as it arrives — even before accounting for any price appreciation in the underlying stock.

This calculator combines both engines of return in one simulation: price growth (the stock or fund becoming more valuable on its own) and dividend reinvestment (income being plowed back in to buy more of that growing asset). You can check current dividend-paying stocks and their yields on our stock data platform and bring those figures directly into the calculator above.

This calculator has two modes, depending on whether you need to account for tax withholding on your dividends.

Standard DRIP

Use this mode for a typical U.S. domestic stock held in a standard or tax-advantaged account with no withholding. Enter your initial investment, the stock's annual dividend yield, an expected annual price growth rate, and the number of years to project. The calculator simulates each year in turn: the balance grows by the price growth rate, then that year's dividend is calculated and immediately reinvested into the balance.

With Tax Withholding

Use this mode for foreign stocks (many countries withhold tax on dividends paid to non-resident investors) or any situation where a known percentage of each dividend is withheld before you can reinvest it. This mode adds a Tax Withholding field — each year's dividend is reduced by that percentage before it is added back into the balance, so the compounding happens on the smaller, after-withholding amount.

In both modes, keep the number of years to 50 or fewer — this keeps the year-by-year simulation fast and the projection within a realistic investing horizon.

Unlike a single-step formula, dividend reinvestment does not have one closed-form equation because the dividend amount changes every year as the balance grows. Instead, the calculator runs a loop, one iteration per year:

Step 1 — Price growth: Value = Value × (1 + Annual Price Growth %)

Step 2 — Dividend: Dividend = Value × Annual Dividend Yield % (in the tax withholding mode, this is further multiplied by (1 − Withholding %))

Step 3 — Reinvest: Value = Value + Dividend

This three-step loop repeats once per year for the number of years you enter, with each year's starting balance being the prior year's ending balance. After the loop finishes, the calculator also reports an effective annualized return using the same logic as a CAGR: (Final Value / Initial Value)^(1 / Years) − 1, so you have a single comparable percentage alongside the raw dollar totals.

To see this in miniature: starting with $10,000 at a 4% dividend yield and 5% price growth, year one grows the balance to $10,000 × 1.05 = $10,500, then adds a dividend of $10,500 × 4% = $420, ending the year at $10,920. Year two repeats the process on that new $10,920 balance, and so on — each year's dividend is calculated on an ever-larger base.

Example 1: A 3-Year Hand-Checkable Walkthrough

Start with $10,000, a 4% dividend yield, and 5% annual price growth, over 3 years. Year 1: balance grows to $10,500, then a $420 dividend is reinvested, ending at $10,920. Year 2: balance grows to $11,466, then a $458.64 dividend is reinvested, ending at $11,924.64. Year 3: balance grows to $12,520.87, then a $500.83 dividend is reinvested, ending at $13,021.71. Over the three years, a total of $1,379.47 in dividends was reinvested, and the effective annualized return works out to 9.20% — higher than either the yield or the price growth rate alone, because each is compounding on top of the other.

Example 2: A 10-Year Standard DRIP Projection

Start with $10,000, a 3% dividend yield, and 6% annual price growth, over 10 years. Running the same year-by-year loop for the full period, the balance reaches $24,067.50, with $4,873.05 of that total coming from reinvested dividends along the way. The effective annualized return is 9.18% — again higher than the 6% price growth alone, because the reinvested dividends are themselves participating in that same 6% price growth every subsequent year.

Example 3: The Same 10 Years, With 15% Tax Withholding

Using the identical starting balance, yield, and growth rate as Example 2, but switching to the withholding mode with a 15% tax withholding rate, the final balance is $23,036.44, with $4,048.89 in net (after-withholding) dividends reinvested. The effective annualized return drops to 8.70%. The roughly $1,031 gap between this result and Example 2 is the compounding cost of losing 15% of every dividend to withholding, year after year — a cost that itself compounds because it is not just the withheld cash you lose, but every future dividend and price gain that cash would have earned had it stayed invested.

Yield and Growth Rate Are Assumptions, Not Guarantees

This calculator projects forward using a constant dividend yield and a constant price growth rate for every year of the simulation. Real stocks cut, raise, or suspend dividends, and their prices rarely rise in a straight line. Treat the output as a "what if this assumption holds" projection, not a forecast, and consider running the calculator multiple times with conservative, moderate, and optimistic assumptions.

Dividend Growth Isn't Modeled Separately

Many healthy dividend-paying companies raise their dividend per share every year, independent of the stock price. This calculator folds that effect into your single dividend yield assumption rather than modeling dividend growth separately from price growth — if you expect meaningful dividend growth on top of price growth, consider using a somewhat higher yield assumption to approximate that combined effect.

Check Whether Your Account Type Withholds Tax

Whether you should use the standard mode or the tax withholding mode depends on your specific stock and account type — U.S. stocks held in a standard U.S. brokerage account typically have no withholding, while many foreign stocks and ADRs do. Confirm your actual withholding rate (commonly found on your brokerage statement or the relevant tax treaty) rather than guessing.

Pair This With a Contribution Calculator If You're Also Adding Cash

This calculator only models the compounding of reinvested dividends and price growth on a lump sum — it does not add new outside contributions during the projection period. If you are also depositing fresh money on a regular schedule in addition to reinvesting dividends, our monthly contributions calculator handles that recurring-deposit scenario.
