💵 Dividend Yield Simulator
How the Dividend Yield Simulator Works
The Dividend Yield Simulator estimates dividend income and total portfolio value over time based on user-defined assumptions. It supports annual, quarterly, and monthly dividend frequencies and allows optional dividend reinvestment to illustrate the long-term impact of compounding.
Purpose of This Calculator
Dividend-focused investing is commonly used to generate cash flow or to build long-term wealth through reinvestment. This calculator helps users understand how dividend frequency, taxation, price growth, and reinvestment decisions mathematically affect portfolio outcomes.
Input Variables Explained
- Number of Shares: Initial quantity of shares owned.
- Stock Price: Starting market price per share.
- Dividend per Share (Annual): Total annual dividend paid per share.
- Investment Period: Holding duration expressed in years.
- Annual Price Growth: Expected average annual stock price appreciation.
- Dividend Tax Rate: Percentage of dividend income deducted as tax.
- Dividend Frequency: Number of dividend payments per year (12 / 4 / 1).
Dividend Frequency Conversion
The calculator converts the annual dividend into periodic payments based on the selected frequency:
Dividend per Period = Annual Dividend ÷ Frequency
For example, with quarterly dividends, one-fourth of the annual dividend is distributed each quarter.
Dividend Income Calculation
For each payment period, dividend income is calculated as:
Dividend Income = Shares × Dividend per Period After-Tax Dividend = Dividend Income × (1 − Tax Rate)
Taxes are applied immediately to dividend income before any reinvestment decisions.
Dividend Reinvestment Logic
When the reinvestment option is enabled, after-tax dividends are used to purchase additional shares at the current stock price:
Additional Shares = After-Tax Dividend ÷ Current Stock Price New Share Count = Previous Shares + Additional Shares
This process increases the share count over time, allowing future dividends to be earned on a growing base—an example of dividend compounding.
Stock Price Growth Assumption
Stock price growth is applied incrementally based on the dividend frequency:
Periodic Price Growth = (1 + Annual Growth Rate)^(1 / Frequency) − 1
This allows price appreciation to align consistently with the dividend payment schedule.
Portfolio Value Tracking
- No Reinvestment: Portfolio value equals share value plus accumulated cash dividends.
- With Reinvestment: Portfolio value equals total shares multiplied by current stock price.
Both scenarios are tracked simultaneously to highlight the long-term difference caused by reinvesting dividends.
Chart Interpretation
- Reinvest Line: Shows compounded growth from reinvested dividends.
- No Reinvest Line: Reflects linear dividend accumulation plus price appreciation.
- Gap Between Lines: Represents the compounding advantage of reinvestment.
Data Sources and Methodology
This calculator does not pull live market or dividend data. All results are generated using user-provided assumptions and standard dividend and compound growth formulas widely used in financial modeling and portfolio analysis.
Limitations
- Assumes stable dividend payments and payout policies
- Assumes constant growth rates over time
- Does not include brokerage fees or transaction costs
- Does not account for dividend cuts, suspensions, or market shocks
