DRIP Calculator
Work out what reinvesting a stock's dividends turns into over time — the shares accumulated, the income it ends up paying each month, and your yield on cost. Then see the same holding with dividends taken as cash, so the decision is visible rather than assumed.

Reinvesting vs taking the cash
The same holding, the same assumptions, run twice. This is the comparison the decision actually turns on, and it is the one most calculators leave you to imagine.
| Reinvested | Taken as cash | |
|---|---|---|
| Total value | $0 | $0 |
| Income next year | $0 | $0 |
| Yield on cost | 0% | 0% |
$0 is what reinvesting added over taking the dividends as cash.
The working
Year-by-year breakdown
Shares accumulating, the dividend per share rising, and yield on cost drifting upward as the payout grows against your original cost.
| Year | Shares | Dividend/share | Income | Reinvested | Value | Yield on cost |

This models one holding with a constant dividend growth rate, in nominal terms. To take the same money and model it as a blended total return — with inflation, fees, tax and an optional withdrawal phase — the compound interest calculator picks up from here with your figures already filled in.

Describe the holding
Amount invested, today's share price, and the current dividend yield. That alone gives you a working projection.
Set the two growth rates
Dividend growth and share price growth are different things. A stock can raise its payout every year while the price goes nowhere, and the result is very different.
Read the comparison
The reinvested column against the cash column. If the gap is small, reinvesting is not the important decision; if it is large, you know why.
Watch yield on cost
Follow it down the year-by-year table. A 3% starting yield growing at 6% a year becomes something quite different against your original cost after twenty years.
How dividend reinvestment is calculated
Each dividend buys more shares, and those shares earn the next dividend. That is ordinary compounding, with one twist: the amount being compounded grows on its own as the company raises the payout.
shares_next = shares + (shares × DPS ÷ 4 × (1 − tax)) ÷ price_at_payment
DPS is the annual dividend per share. Dividends are treated as quarterly, and each reinvestment buys at that quarter's share price rather than the price at the start of the year — ignoring that drift overstates how many shares accumulate.
How to calculate dividend yield
Dividend yield is the annual dividend per share divided by the current share price. A $2.00 annual dividend on a $50 share is a 4% yield. It moves inversely with the price, so a falling share price raises the quoted yield without the company having done anything — which is why a very high yield is often a warning rather than a bargain.
Yield on cost, and why it is not the same thing
Yield on cost divides the dividend you now receive by what you originally paid, rather than by today's price. On this page it is your whole forward annual dividend divided by your original investment, so with reinvestment switched on it captures two effects at once: the rising payout per share, and the extra shares you accumulated. Buy at $50 with a $1.50 dividend and you start at 3%. Take the dividends as cash and 6% annual growth lifts the payout to about $4.81 after twenty years — roughly 9.6% on cost. Reinvest instead and the same holding reaches about 19% on cost, because you now own roughly twice as many shares. The comparison table shows both figures side by side. Either way it measures how a long hold has developed; it says nothing about whether the shares are worth buying today, for which the current yield is the relevant number.
Why dividend growth and price growth are separate here
Most dividend calculators ask for one 'expected return' and apply it to everything. That conflates two independent things: how fast the company raises its payout, and what the market pays for the shares. A holding whose dividend grows 8% while the price grows 2% accumulates shares quickly at cheap prices; the reverse accumulates slowly at expensive ones. Same blended return, very different outcome — and the difference is invisible unless the inputs are separate.
Tax on dividends
In a taxable account, tax is deducted from each dividend before anything is reinvested, so it does not merely reduce your income — it permanently reduces the number of shares you accumulate, and those shares would have paid dividends of their own. The model applies one flat rate to every payment. It does not distinguish qualified from ordinary dividends, model withholding on foreign shares, or handle allowances. Set the rate to 0 for an IRA, 401(k) or ISA.
Whole shares or fractions?
Broker-run reinvestment usually buys fractional shares, so every cent goes back to work. Some company-operated plans buy whole shares only and hold the remainder as cash until it is enough. Turning that option on carries the leftover cash forward to the next payment rather than quietly dropping it, which would make DRIP look better than it is.
Why there is no ticker box
People search for a dividend calculator 'by ticker', and some competitors offer one. This site deliberately holds no live market data: nothing you type is sent anywhere, there is no account, and there is no price feed to go stale or wrong. The trade is that you enter the share price, yield and growth rate yourself — which also means you always know exactly which assumptions produced the answer. Current figures are on any broker page or in the company's latest report.
Worked examples
Each reproducible with the calculator above.
- $10,000 at $50 a share, 3% yield, 6% dividend growth, 4% price growth, 20 years. The reinvested column ends materially above the cash column, and the gap is what the reinvestment decision was worth.
- The same holding with price growth set to 0. Income keeps compounding even though the shares go nowhere — this is the scenario dividend investors actually have in mind.
- A 3% starting yield growing 6% a year. Yield on cost climbs to roughly three times the starting yield over two decades, visible year by year in the table.
- Add a 15% dividend tax. The final value falls by about 10% on these inputs — more than the tax bill alone, because the shares that tax would have bought would themselves have paid dividends for the rest of the term.
- Switch to whole-share reinvestment. Small holdings lose noticeably more to idle cash than large ones.
DRIP calculator FAQ
Dividend reinvestment, yield on cost, tax and what this calculator deliberately does not do.
DRIP basics
What is a DRIP?
A dividend reinvestment plan. Instead of paying dividends to you as cash, each payment automatically buys more shares of the same stock, which then earn dividends themselves. Most brokers offer it as a free toggle on any holding.
Is reinvesting dividends actually worth it?
That is exactly what the comparison table answers for your own numbers. Reinvesting compounds the position; taking the cash gives you income now and the option to spend or reinvest elsewhere. The gap between the two columns is the value of the decision — it is often large over decades and modest over a few years.
How is this different from a compound interest calculator?
A compound interest calculator applies one blended growth rate. This one tracks shares, dividend per share and price separately, so you can see how many shares you accumulate and what income the holding pays — figures a blended rate cannot produce.
Is this free? Do I need an account?
Free, no account, no ads. Everything runs in your browser and nothing you type is transmitted or stored.
Can it show monthly dividend income?
Yes. The headline shows both annual and monthly forward income — what the holding will pay over the coming year, divided by twelve. Note that most US stocks pay quarterly, so real income arrives in four lumps rather than evenly each month.
How often are dividends assumed to be paid?
Quarterly, which matches most US-listed companies. Each reinvestment buys at that quarter's share price rather than a single annual price, so share accumulation is not overstated.
Inputs
What share price should I enter?
Today's price, from your broker or any quote page. It sets how many shares your investment buys at the start, so it matters more than it looks.
What dividend yield should I use?
The current annual dividend divided by the current share price, which most quote pages show directly. Use the trailing figure unless the company has announced a change.
What dividend growth rate is realistic?
Check the company's own record over five and ten years — that history is the best available guide. Long-standing dividend growers have often managed 5-8% a year, but no rate is guaranteed and dividends can be cut.
Should price growth be the same as dividend growth?
Not necessarily, and forcing them to be equal is the assumption this calculator exists to avoid. Over very long periods a stable payout ratio implies they converge, but over any realistic holding period they diverge, and the divergence changes how cheaply your dividends buy shares.
What if I set price growth to zero?
You see the income effect in isolation: dividends still compound into more shares, and because the price is not rising, each dividend buys more of them. It is a useful way to check that a thesis rests on the payout rather than on the market re-rating the stock.
Can I model a falling share price?
Yes, enter a negative price growth rate. It is a worthwhile sanity check: reinvesting into a genuinely declining business buys more and more of something worth less, which the raw share count alone will not tell you.
What dividend tax rate should I enter?
For a tax-sheltered account, 0. For a taxable account, whatever rate applies to your dividends. The model uses one flat rate and does not distinguish qualified from ordinary dividends or handle allowances — it is a simplification, not tax advice.
Income and yield
What is yield on cost?
The current annual dividend divided by what you originally paid per share, rather than by today's price. It shows how a long hold has developed. A 3% yield growing 6% a year is close to 9.6% on cost after twenty years.
Is yield on cost a useful metric or a vanity one?
Both, depending on use. It is a fair measure of how a position has performed for you. It is not a reason to keep holding, because the money you have tied up is worth today's price, not what you paid — the relevant comparison for a new decision is always the current yield.
Why is income shown for the next year rather than the last one?
Because that is the figure you plan around. It is the share count you have accumulated multiplied by the dividend per share now in force.
What is the dividend yield formula?
Annual dividend per share divided by share price, expressed as a percentage. A $2.00 dividend on a $50 share is 4%. Yield on cost uses the same numerator with your original purchase price as the denominator.
Should I just pick the highest-yielding stock?
A very high yield usually means the market expects a cut, since yield rises automatically as the price falls. This calculator will happily project a 12% yield growing forever; reality frequently will not. Treat an unusually high yield as a question rather than an opportunity.
Limits
Can I enter a ticker instead of typing the numbers?
No, deliberately. The site holds no live market data at all — that keeps it fast, private and free of a price feed that could be wrong. You supply the price, yield and growth rate, which also means you always know which assumptions produced the result.
Does it model dividend cuts?
Not as an event. Growth is a constant rate, so you can model a permanently lower rate but not a suspension in year seven followed by a recovery. Dividend cuts are the main risk this kind of projection understates.
Does it account for share price volatility?
No. Price growth is constant. In reality, reinvesting during a decline buys more shares cheaply and can improve the outcome — an effect a smooth model cannot show in either direction.
Are commissions or plan fees included?
No. Most brokers now reinvest dividends free of charge, so the default assumption is zero cost. If your plan charges, the real result will be slightly below what is shown here.
Are the figures adjusted for inflation?
No — everything on this page is nominal. For an inflation-adjusted view, follow the link below the table into the compound interest calculator, which restates the balance in today's money.
Can I model a whole portfolio of dividend stocks?
Not in one run. Model each holding separately, or use a blended yield and growth rate as an approximation. A true portfolio view would need per-holding data the site does not store.
Why does my broker's projection differ?
Usually payment timing and the price used for reinvestment. This model uses quarterly payments reinvested at that quarter's drifting price; a broker may use annual figures, a single price, or include fees. The assumptions are stated above so you can line them up.

Method and limitations
Dividends are treated as quarterly. Each payment is the current share count multiplied by a quarter of the annual dividend per share; tax is deducted, and the remainder buys shares at that quarter's price, which drifts upward through the year in line with your price growth rate. Dividend per share and share price then each grow by their own annual rate. Yield on cost divides the forward annual dividend by the original amount invested. The comparison column runs the identical scenario with reinvestment switched off and dividends accumulated as cash.
Dividend growth and price growth are constant rates, so dividend cuts, suspensions and volatility are not modeled — and a cut is the main risk here. Figures are nominal, before inflation. Tax is a single flat rate with no distinction between qualified and ordinary dividends. Commissions are assumed to be zero. No live market data is used. Nothing here is investment or tax advice.
