Compound Growth
Dividend Reinvestment Calculator: DRIP vs. Cash Payout
Reinvesting dividends buys more shares, so each future payout is larger. A $10,000 position with 7% price growth and a 3% dividend yield grows to $69,890.81 over 20 years when dividends are reinvested, versus $51,856.40 taking them as cash — reinvesting is worth $18,034.41 more.

Reinvesting a 3% dividend on $10,000 at 7% annual price growth turns $18,830 of payouts into $18,034 of extra value over 20 years, versus taking them as cash.

The dividend you can see, and the one you cannot
A dividend is the most tangible piece of investing: cash appears, quarter after quarter, and you choose what to do with it. The instinct is to treat it as income. The reinvestment plan is the quieter option — the payout is used to buy more of the same position, so the cash you never touch is the cash that keeps working.
The calculator above makes that choice explicit. Both paths start from the same principal and appreciate at the same annual rate. The only difference is what happens to each dividend: one path reinvests it, the other banks it as cash. The spread between the two lines is therefore nothing more than the compounding effect of reinvestment — no different rate, no timing trick.
The formula
Both paths grow by the same price factor each year. The reinvested path then adds the dividend back into the position:
Where g is the annual price growth as a decimal and y is the annual
dividend yield. The cash path grows the position by (1 + g) alone and sets
each year’s P_t y payout aside uninvested. The reinvested path’s advantage is
the (1 + y) factor compounding each year — the payout becomes principal for
the next payout.
The default example, line by line
The loaded scenario — $10,000, 7% price growth, a 3% yield, 20 years — ends with $69,890.81 reinvested and $51,856.40 in the cash path. The $18,034.41 difference is not a different return; it is the same return compounded through $18,829.53 of reinvested dividends. Nearly a fifth of the final reinvested balance exists only because earlier dividends were put back to work.
That effect is invisible in year one. After a single year the two paths tie at $11,021.00, because the first dividend has not yet had time to earn its own dividend. By year five the reinvested path is only $387.91 ahead. It is only in the back half of the horizon that the compounding overtakes the arithmetic, and the gap becomes the headline.
The growth rate does the heavy lifting
The dividend reinvestment edge depends entirely on price growth staying positive. Here is the same $10,000 over 20 years at a 3% yield, across growth assumptions:
| Price growth | Reinvested balance | Cash balance | Reinvesting edge |
|---|---|---|---|
| 0% | $18,061.11 | $16,000.00 | $2,061.11 |
| 5% | $47,921.51 | $36,948.75 | $10,972.76 |
| 7% | $69,890.81 | $51,856.40 | $18,034.41 |
| 10% | $121,506.13 | $86,175.75 | $35,330.38 |
At 0% growth, reinvesting still wins — dividends are added to a flat position, and the cash path simply accumulates the payouts without earning anything on them. The edge grows with growth, but so does the gap between the two paths in absolute dollars, which is the point: the longer and faster a position grows, the more reinvesting dividends matters.
When reinvesting hurts
Reinvesting is not a universal win. If price growth turns negative, every
reinvested dividend is used to buy shares that then decline. The (1 + y)
factor that compounded the gains now compounds the loss, and the reinvested
path ends below the cash path. Drag the growth input negative in the calculator
and the “Extra From Reinvesting” figure flips sign — the honest behavior the
headline does not assume.
This is the reason dividend reinvestment is framed as a long-horizon default rather than a rule: the strategy works precisely when you expect the position to appreciate, which is also when you should already be holding it.
How to use this comparison
Set the price growth to your honest expectation, keep the yield at the position’s current dividend, and read the “Extra From Reinvesting” figure as the compounding premium of choosing DRIP. If the position is a broad index fund held for decades, the reinvested path is the appropriate default; if it is a single stock you are already planning to exit, taking the cash may be the sounder use of the payout.
Then run the same inputs through the compound interest calculator. That tool adds monthly contributions to the picture; this one isolates the dividend decision. The two together answer the full question of what a position becomes — the contributions you add, and the payouts you let compound.
The assumptions
The calculator assumes a single fixed dividend yield paid once per year, a constant price-growth rate, no fees, and no taxes. Dividends are reinvested at the year-end price. Both paths are pre-tax; in reality a taxable account taxes dividends the same whether you reinvest them or take cash, so the tax drag cancels out of this comparison even though it would lower both final balances.
Frequently asked questions
What is a dividend reinvestment plan (DRIP)?
A DRIP automatically uses each cash dividend to buy more shares of the same investment instead of depositing the cash. Because the new shares earn the next dividend, the position grows faster than it would if you took every payout as cash. The reinvestment is usually commission-free and buys fractional shares, so even small dividends are put back to work.
Does reinvesting dividends always beat taking them as cash?
No. Reinvesting beats cash only while the position is growing; it compounds a loss when the position is falling, because each reinvested dividend is used to buy shares that then decline too. In this calculator, dragging price growth negative makes the reinvested path end below the cash path — the difference flips sign exactly when growth turns negative.
Why does the reinvested balance outgrow the cash balance at the same price growth?
Both paths appreciate at the same rate, but the reinvested path adds each dividend to the position, buying shares that then pay the next dividend. The cash path keeps those payouts uninvested, so they do not grow. The gap between the two is therefore the compounding effect of the reinvested dividends themselves, not a higher rate of return.
Does this calculator account for taxes on dividends?
No. It shows pre-tax growth. Dividends in a taxable account are generally taxed in the year they are paid whether you reinvest them or take cash, so the tax drag is the same either way and drops out of the comparison. The calculator isolates the compounding effect of reinvestment and assumes no fees and a constant yield.
