About This Dividend Reinvestment Calculator
This dividend reinvestment calculator models how reinvested dividends can increase your share count over time. Enter your starting shares, current share price, annual dividend per share, projection length, reinvestment percentage, growth assumptions, and optional annual contributions.
The result compares a reinvestment scenario with a cash-dividend scenario using the same price, dividend, and contribution assumptions. That makes it easier to see how much of the projected ending value comes from buying additional shares with dividends rather than simply holding the original position.
The calculator is deliberately assumption-led. It does not fetch live prices, select investments, forecast company payouts, model tax, or account for broker fees. Use it as a planning model for understanding DRIP mechanics, not as an investment recommendation.
How the dividend reinvestment model works
For each projection year, the calculator estimates dividends by multiplying the share count by the annual dividend per share.
The reinvested portion of those dividends is divided by the current share price to estimate how many additional shares are bought.
The model then applies your dividend-growth and price-growth assumptions for the next year. This repeats until the final projection year.
DRIP compared with taking cash dividends
The cash-dividend comparison uses the same starting holding, price growth, dividend growth, and contributions, but it does not use dividends to buy more shares.
The difference between the two ending portfolio values shows the estimated value created by reinvested dividends under your assumptions.
Cash dividends are not automatically worse. If you need income, or if fees, tax, diversification, or valuation make reinvestment unattractive, taking cash can still be a rational choice.
Dividend reinvestment example
Suppose you start with 250 shares priced at GBP 20, each paying GBP 0.80 per year. A full reinvestment plan uses every dividend payment to buy more shares, while an annual contribution adds extra shares on top.
If dividends and share price both grow, the later years often contribute more to the ending value because the share count is larger and each share may be paying a higher dividend.
Changing the reinvestment percentage is useful for modelling a partial-income approach, where some dividends are spent and the rest are reinvested.
Important limits of a DRIP projection
The calculator does not fetch live share prices, verify dividend histories, or predict whether a dividend will be maintained.
It excludes tax, withholding tax, platform fees, foreign exchange, bid-ask spreads, fractional-share restrictions, and account-specific reinvestment rules.
Because dividends and prices can fall as well as rise, test weaker growth assumptions before treating any projection as a realistic plan.

It projects share accumulation, dividends, and ending value from entered assumptions. It does not fetch live market prices, recommend investments, calculate dividend tax, or verify company payout sustainability.
How to Use This Calculator
- 1
Enter your starting holding
Add the number of shares you own, the current share price, and the current annual dividend per share.
- 2
Set growth assumptions
Enter assumed dividend growth and share price growth. Use conservative values if you want a stress-test style projection.
- 3
Choose reinvestment rate
Set the percentage of dividends reinvested. Use 100% for a full DRIP, 0% for cash dividends, or a partial rate if you plan to spend some income.
- 4
Compare outcomes
Review ending shares, ending value, total dividends, reinvested dividends, and the difference versus taking dividends as cash.
Frequently Asked Questions
What is dividend reinvestment?
Dividend reinvestment means using dividend payments to buy more shares instead of taking the dividends as cash. Those extra shares can then earn future dividends, creating a compounding effect.
Does this calculate dividend tax?
No. The calculator is gross before tax and does not include tax allowances, account wrappers, withholding tax, or jurisdiction-specific dividend rules.
Does it use live share prices?
No. You enter the share price and growth assumption manually. The calculator does not fetch market data or verify company dividend history.
Why compare with cash dividends?
The comparison helps separate normal investment growth from the extra share accumulation caused by reinvesting dividends. It uses the same assumptions so the two scenarios remain consistent.
Is this a DRIP return calculator?
It projects shares, dividends, and ending value under reinvestment assumptions, but it is not a total-return guarantee. Real results depend on market prices, dividends, fees, tax, and timing.
Can dividends be partly reinvested?
Yes. Set the reinvested percentage below 100% to model taking some dividend income as cash while reinvesting the rest.
Why include annual contributions?
Many investors reinvest dividends and also add new money. The contribution field lets you include those extra purchases while still seeing the separate total of reinvested dividends.
