Dividend Reinvestment Growth Projection Calculator
Project shares, market value, dividend income, contributions, reinvestment, and yield on invested cash.
Shares and income dual-growth map
Share count staircase, market-value curve, and annual dividend-income rail
The visual separates share accumulation from market repricing and dividend growth.
Live decision table
Share, value, and income checkpoints
Review shares, price, market value, dividends, and invested cash each year.

How to use
Separate share growth from income growth
- Use current account or security documents.
- Keep rates, timing, taxes, and cash flows explicit.
- Change one assumption at a time.
- Compare the result with a practical liquidity need.
Calculation logic
Price and dividend per share are independent drivers
Contributions buy fewer shares as price rises, while dividend growth can still raise income per share.
The live table preserves intermediate values instead of reducing the decision to one headline number.
Calculation method
Simulate share purchases, dividend reinvestment, and changing price and dividend per share
Monthly contributions and after-tax dividends buy shares at the projected price. Dividend per share grows independently from market price.

Decision audit
Check constraints the arithmetic cannot guarantee
- Confirm contractual dates and penalties.
- Stress rates and reinvestment assumptions.
- Separate taxable and protected accounts.
- Preserve emergency liquidity.
Decision anatomy
What creates ending income
The diagnostic cards isolate the drivers most likely to change the decision.
Shares owned
—Opening shares plus contribution and DRIP purchases.
Annual income
—Ending shares times projected dividend per share.
Yield on cost
—Ending dividend income relative to invested cash.
Decision takeaway: Review share count, income, and valuation together.
Practical applications
Decisions this calculator is designed to support
Long-term DRIP plan
Monthly contributions and dividends both buy shares.
What the result clarifies: The dual map reveals which source drives share growth.
Dividend growth above price growth
Income per share grows faster than price.
What the result clarifies: Yield dynamics differ from a constant-yield shortcut.

This deterministic projection does not model volatility, dividend cuts, fees, trading dates, withholding, or sequence effects.
Dividend Reinvestment Growth Projection Calculator FAQ
Why project price and dividend growth separately?
They affect share purchases and income differently.
Does the model include fractional shares?
Yes.
Is yield on cost a current market yield?
No. It compares projected income with invested cash.
