Quick Answer: What does a DRIP do?
A dividend reinvestment plan uses dividends to buy additional shares instead of paying them out as cash, changing share count and basis. Future dividends and prices determine the result, so a projection cannot promise a return. In a US taxable account, reinvested dividends can still be reportable income.
Try it: compare the calculator’s default example
The DRIP calculator opens with $10,000, 4% annual yield, $0 added each year, 5% assumed annual price growth, and quarterly dividends. Note the default investment period and projected value. Change only the payment frequency to monthly and recalculate. Write which assumption changed and why neither result is a forecast. The model does not subtract US dividend tax, fees, or inflation.

How DRIP Works: When you reinvest dividends, each payment is used to buy more shares. Those additional shares generate their own dividends, which buy even more shares. Over time this creates an accelerating compounding effect. Enter your details above to see the numbers.
Educational content only. Projections assume constant dividend yield, price appreciation, payment frequency and contribution amounts. They do not account for taxes, dividend cuts, brokerage fees, inflation, currency effects or variable market returns. Use as a planning guide only.
$10,000 invested with a 4% dividend yield, 5% price appreciation, quarterly DRIP and a 10 year horizon grows to about $24,252, with $6,364 of that coming from reinvested dividends. DRIP turns each dividend payment into additional shares, which then earn their own dividends. Over long horizons, the compounding on share count materially boosts total return.

How to use the DRIP calculator
Project reinvested-dividend growth in three steps.
1
Enter initial investment and yield
Starting dollar amount and current annual dividend yield. Use trailing twelve month yield from the issuer factsheet.
2
Set price appreciation and frequency
Annual price growth (5% is common). Pick dividend payment frequency (most US payers are quarterly).
3
Read the final portfolio value, dividends earned and total return
The result panel shows three big cards (Final Portfolio Value, Total Dividends Earned, Total Return %) and a detailed projection table (initial investment, total contributions, total invested capital, dividends reinvested, price appreciation gains, final portfolio value, total gain). The Total Return % captures both reinvested-dividend compounding and price appreciation in a single comparable number.

Why use this DRIP calculator
Specific outcomes, not generic claims.
🔄
See the compounding effect
Cash dividends grow income linearly. DRIP grows shares which grow income which buys more shares. The curve bends.
⏱️
Compare frequencies
Monthly DRIP compounds faster than quarterly which compounds faster than annual. Test the difference on long horizons.
📈
Total return view
Most calculators show price OR income. DRIP shows the combined effect: price appreciation plus reinvested dividend compounding.
The math behind the projection
Most calculators hide the formula. We show it because understanding the math is the point.
📐 Formula
Each period: collect dividend, buy more shares, apply price appreciation, optionally add contribution. Repeat across the period count.
Per period: Balance += Balance × (Yield/Freq), then Balance ×= (1 + Growth/Freq), then + Contribution
Balance current portfolio value in dollars · Yield annual dividend yield as a decimal · Freq dividend payment frequency per year (4 quarterly, 12 monthly) · Growth annual price appreciation as a decimal · Contribution annual contribution divided by Freq for per period addDRIP is iterative, not closed form. The calculator runs the loop period by period, collecting and reinvesting dividends, applying price growth, and optionally adding contributions. More frequent payments compound slightly faster because dividends start earning their own dividends sooner.
What this calculator assumes vs reality
The projection is a mathematical model, not a forecast. Six assumptions baked into the math, plus what real outcomes look like.
⚠️ Six assumptions to know about
Each card pairs an assumption the calculator makes with what real world investing actually looks like.
Yield constant
Reality: Real yields change as price moves. A price drop raises yield (reinvested shares get cheaper).
Price growth constant
Reality: Real prices are volatile. The smooth 5% path is an average, not a sequence.
Dividend never cut
Reality: Companies cut in recessions. DRIP into a falling dividend stock can be a value trap.
No tax
Reality: Dividends are taxable income in most accounts even when reinvested.
No fees
Reality: Some DRIP programs charge per transaction fees, especially for fractional shares.
Fractional shares allowed
Reality: Most modern brokers handle fractional shares; older programs may round.
Account and tax context: Tax treatment depends on the account. In a US taxable account, a dividend can be taxable when paid even if it is reinvested. US tax-advantaged accounts follow different rules; this calculator does not calculate tax.
How small input changes shift the result
Start with $10,000, a 4% yield, 5% annual price growth, quarterly reinvestment and 10 years. Change one input at a time; these are modeled outcomes, not forecasts.
| Scenario | Yield | Period | Final value | Final value vs base |
|---|---|---|---|---|
| Base case | 4% | 10y | $24,252 (+142.5%) | Base |
| Half yield | 2% | 10y | $19,885 (98.9% return) | -18% |
| Double yield | 8% | 10y | $35,967 (259.7% return) | +48.3% |
| 20 year horizon | 4% | 20y | $58,816 (488.2% return) | Different horizon |
| Add $1k/yr contribution | 4% | 10y | $39,637 (98.2% return) | Adds $10,000 |
| Lower price growth (2%) | 4% | 10y | $18,149 (81.5% return) | -25.2% |
The last column compares final balances for otherwise matching scenarios. A longer horizon or new contributions also changes time or money invested, so no percentage comparison is shown for those rows.
The pattern: In this calculator, extending the horizon gives reinvested dividends more time to buy shares. Change one input at a time to see how the modeled outcome responds. These smooth scenarios are illustrations, not historical return predictions.
DRIP vs cash dividends over time
The calculator assumes smooth price growth and a steady dividend yield. Historical market returns vary year to year, so compare matching dates and methods before using them as context.
| Comparison | What it measures | What to check |
|---|---|---|
| Price return | Change in the index level without reinvested dividends | Use the same dates and index version when comparing returns |
| Total return | Price changes plus dividends reinvested | Check whether the historical series already includes dividends |
| Cash dividends | Distributions retained outside the position | Count the portfolio value and cash received together |
| Dividend reinvestment | Distributions used to buy additional shares | Consider tax, fees, dividend changes and variable prices |
The key insight: Reinvestment changes the share count and the path of compounding. A historical total-return series already includes dividends; adding a separate dividend yield to that same series would count them twice. Past index returns do not forecast an individual holding.
Dividend reinvestment, everything you need to know
DRIP (Dividend Reinvestment Plan) automatically uses each dividend payment to buy more shares of the same security. Over time the share count grows, which means future dividends are larger, which buys more shares, which generates more dividends. The compounding effect is the entire point.
Most modern brokers offer DRIP for free on most US stocks and ETFs, including fractional shares. Some companies operate their own DRIP programs with discounted reinvestment prices, though these have become less common as broker DRIPs have grown.
The difference between reinvesting and retaining cash can grow over time in a steady-input model. The actual outcome depends on changing prices, dividends, taxes, fees and what happens to cash that is not reinvested.
How to set your assumed return rate
Use trailing twelve month yield as the input. For ETFs and most stocks this is on the issuer or broker page.
Treat price growth as a scenario input, not a forecast. Try several rates, including zero or negative growth, and compare how much the result changes.
Common mistakes
- DRIP into a value trap. A high yield from a falling price can mean dividends about to be cut.
- Forgetting tax in a taxable account. You owe tax on the dividend even when reinvested.
- Ignoring fees on small DRIP transactions. Per transaction fees can drag returns on small positions.
- Confusing total return with income. DRIP grows portfolio value, not cash income.
- Assuming uniform growth. Real prices are volatile; the smooth projection hides volatility.
- Ignoring account tax rules. Reinvested dividends can still be taxable in a US taxable account; account type and personal circumstances matter.
How to interpret your result
Read three numbers: final portfolio value, total dividends reinvested, and total return percentage. The dividend total shows how much was reinvested under the assumed yield; it is not a clean attribution of the final gain between dividends and price.
Compare with vs without DRIP for the same inputs. The gap shows the value of the reinvestment decision over your horizon.
S&P 500 price versus total return — updated through 2025
The index provider’s December 2025 report, page 2 supplies these four calendar-year returns (checked October 8, 2026). Price return excludes dividends. Total return includes their reinvestment. This compares two versions of the same index, not two stocks or a promised personal DRIP outcome.
| Year | Price return | Total return |
|---|---|---|
| 2022 | -19.44% | -18.11% |
| 2023 | 24.23% | 26.29% |
| 2024 | 23.31% | 25.02% |
| 2025 | 16.39% | 17.88% |
In 2025, the total-return advantage was 17.88 − 16.39 = 1.49 percentage points. An assumed $1,000 at the start of that year becomes $1,163.90 using price return or $1,178.80 using total return, a $14.90 difference.
To show compounding across 2022–2025, assume $1,000 at the start of 2022 and no added contributions or withdrawals. Price-only: $1,000 × 0.8056 × 1.2423 × 1.2331 × 1.1639 = $1,436.35. With index dividend reinvestment: $1,000 × 0.8189 × 1.2629 × 1.2502 × 1.1788 = $1,524.12. The approximate difference is $87.77, calculated from rounded annual inputs rather than a personal account statement.
Reinvested dividends did not prevent a loss in 2022. An index total-return calculation assumes reinvestment before investor fees and taxes. A broker’s DRIP timing, purchase price, fractional-share policy, costs and taxes can change actual results. An index cannot be bought directly; a tracking fund can differ. Use the existing calculator to test assumptions, keeping its projected figures separate from this historical table.
Key takeaways
- Price return omits dividends; total return includes reinvestment.
- Compound each annual growth factor instead of adding annual percentages.
- Reinvestment does not remove loss risk or an investor’s costs and taxes.

High yield REIT 20 year
Income focused investor uses DRIP to compound a REIT position over decades.
Result: Final $149,465. Reinvested dividends $83,214. Total return roughly 498%. Most of the gain came from dividend compounding, not price appreciation.
Aristocrat long hold no contributions
Buy and hold Aristocrat compounder with quality dividend growth and moderate price appreciation.
Result: Final $431,086. Reinvested dividends $122,499. Total return roughly 762%. DRIP adds materially even though current yield is modest.
Cash vs DRIP comparison
This separate comparison counts both the ending share value and cash dividends received. It excludes tax and fees.
Result: Cash version: portfolio $16,288.95 + $5,124.53 dividends collected = $21,413.48 total. DRIP version: $24,252.02. Difference in this model: $2,838.54 over 10 years.
Frequently asked questions
The questions users most often ask about calculator output.
Is the DRIP Calculator free?
Yes. free to use. Your inputs are not stored or shared.
Should I always DRIP?
Not automatically. Compare your cash needs, concentration, fees, account rules, and tax treatment. Reinvestment buys more of the same investment but does not guarantee a higher return.
How often does DRIP happen?
On each dividend payment date. Most US dividend payers are quarterly. Some ETFs are monthly. Pick the matching frequency in the calculator.
Does DRIP work with fractional shares?
Modern brokers (Schwab, Fidelity, Vanguard, Robinhood and similar) reinvest into fractional shares automatically. Older company sponsored DRIPs may round to whole shares.
Is DRIP taxed?
Yes in a taxable account. You owe tax on the dividend even when reinvested. The reinvested amount adds to your cost basis to avoid double tax on eventual sale.
Does the calculator include US dividend tax?
No. This projection does not subtract tax. IRS Publication 550 explains that reinvested dividends can still be taxable in a US taxable account.
Why is monthly slightly better than quarterly?
In this model, more frequent payments can change the projection when all other assumptions stay fixed. Actual payment schedules, prices, fees, and dividend decisions vary.
What if the dividend is cut?
DRIP keeps reinvesting whatever dividend the company pays. If a cut happens, future reinvestments are smaller. The calculator assumes the dividend never cuts.
