Equity Return Calculator
Project the future value of a stock or ETF position with price growth, dividends, and optional reinvestment.
Best used for
Projects how a stock or ETF position may grow through price appreciation, dividends, and optional reinvestment.
Projection outlook
See how the modeled path evolves over time under the current assumptions.
Optimistic currently leads conservative by about $34,147.
How it works
The calculation, without the clutter
Each year, the model updates share price based on the annual growth assumption and applies your planned annual contribution.
Dividend income is calculated from the position value using the dividend yield.
If dividends are reinvested, the model converts that cash into additional shares at the current modeled price.
Where this tool is most useful
An investor holding 120 shares of an ETF at $210 per share can model how annual contributions, price appreciation, and dividend reinvestment may change the position over the next decade.
Key assumptions
What to sanity-check
- The model assumes one annual contribution and one annual dividend cycle for simplicity.
- Dividend yield is treated as stable across the projection horizon unless you adjust it manually.
- Price growth and dividends are smooth planning assumptions rather than a forecast of market volatility.

Common questions
Can I use this for ETFs too?
Yes. The model works for a single stock or ETF position as long as you enter the price, shares, yield, and annual contribution assumptions.
Does this pull live market data automatically?
It can optionally autofill share price and dividend yield from the market-data layer, but the model still works fully with manual inputs.
What if the company cuts its dividend?
Update the dividend yield assumption. The model is only as accurate as the payout assumption you enter.
Should I reinvest dividends automatically?
Reinvestment can accelerate share growth, but some investors may prefer cash income. This model lets you compare both paths.
