Project shares and holding value when annual cash dividends buy additional shares.
It makes the prices, cash flows, rates, time periods, weights, and model conventions explicit so you can inspect an entered scenario without hidden live-market assumptions.
Calculation structure
Follow the stated model and units
Each year: dividend cash = shares × dividend per share; new shares = cash ÷ current price; then price and dividend grow.

Read the estimate correctly
Use the result within its boundaries
100 shares at price 50 with a 2 annual dividend reinvest that year's 200 into four shares before the next annual growth step.
Dividends are assumed paid and reinvested once per year at the current modeled price; taxes, fees, fractional-share restrictions, and dividend cuts are excluded.
Quick guide
How to use this calculator
Enter the cash flows, values, rates, timing, or portfolio assumptions named in the fields.
Use one consistent period and currency convention throughout the scenario.
Read the calculator-specific model limits before interpreting the result.
