Return on Security Calculator
When you invest in a security—like stocks, bonds, or ETFs—you want to know how well your investment has performed over time. That's where the Return on Security Calculator becomes an essential tool. This calculator helps you evaluate how profitable your investment has been by taking into account not just the capital gains, but also dividends or other income received during the holding period.
Whether you're a long-term investor or a short-term trader, knowing your annualized return can help you make smarter financial decisions and compare investment options more effectively.
Formula
To calculate the Return on Security, use the following formula:
Annualized Return (%) = [(Final Price + Dividends) ÷ Initial Price] ^ (1 ÷ Years Held) - 1 × 100
Where:
- Initial Price is the amount paid to purchase the security.
- Final Price is the amount for which the security was sold.
- Dividends are the total income received while holding the security.
- Years Held is the length of time the security was held before selling.
This formula gives you the compound annual growth rate (CAGR) of your investment.
How to Use
- Enter Initial Price: Input the amount you originally paid for the security.
- Enter Final Price: Enter the price at which you sold (or the current market value).
- Enter Dividends: Input the total income earned while holding the investment.
- Enter Time Held: Indicate how many years you held the security.
- Click Calculate: The calculator will show your annualized return on the security.
This result shows your average yearly return, factoring in both appreciation and income.
Example
Let’s say you bought a stock for $1,000, earned $100 in dividends, and sold it for $1,500 after 3 years.
Using the formula:
Annualized Return (%) = [(1500 + 100) ÷ 1000] ^ (1 ÷ 3) - 1 × 100
= (1.6)^(1/3) - 1 × 100 ≈ 17.65%
So your return on security is approximately 17.65% per year.
