1. What is Stock Return Calculation?

The stock return calculation measures the percentage gain or loss on an investment over a specific period, accounting for both price changes and dividend payments. It's a fundamental metric for evaluating investment performance.

2. How Does the Calculator Work?

The calculator uses the stock return formula:

\[ \text{Return} = \frac{\text{Final Price} - \text{Initial Price} + \text{Dividends}}{\text{Initial Price}} \times 100 \]

Where:

Final Price — Current or selling price of the stock
Initial Price — Original purchase price of the stock
Dividends — Total dividends received during holding period

Explanation: The formula calculates total return by considering both capital gains/losses and dividend income, expressed as a percentage of the original investment.

3. Importance of Return Calculation

Details: Calculating investment returns helps investors compare performance across different assets, assess investment strategies, and make informed decisions about portfolio allocation.

4. Using the Calculator

Tips: Enter all values in dollars. Initial Price must be greater than zero. Dividends can be zero if none were received during the holding period.

5. Frequently Asked Questions (FAQ)

Q1: Should I include brokerage fees in the calculation?
A: For precise personal returns, you could subtract fees from the final price or add them to the initial price, but this calculator uses the basic formula.

Q2: What time period does this calculate returns for?
A: The formula works for any time period - daily, monthly, or annual returns. The period is determined by your price inputs.

Q3: How does this differ from annualized return?
A: This calculates total return for the period. Annualized return adjusts for the holding period length to enable year-to-year comparisons.

Q4: Should dividends be reinvested or cash?
A: This calculation treats dividends as cash payments. For total return with reinvested dividends, you'd need to account for additional shares purchased.

Q5: Can this be used for other investments?
A: Yes, the same formula works for any asset where you can measure price changes and income (like mutual funds or ETFs).
