How to Calculate Return Rate Percentage
Understanding how to calculate your return rate percentage (often referred to as Rate of Return or RoR) is fundamental to evaluating the success of any investment, business venture, or asset appreciation. It converts absolute dollar gains into a standardized percentage, allowing you to compare investments of different sizes.
The calculation determines the percentage change in value of the investment from the beginning of the period to the end, accounting for any additional income generated (such as dividends, interest, or rent).
The Return Rate Formula
The standard formula for calculating the simple rate of return is:
RoR = [(Final Value – Initial Value + Income) / Initial Value] × 100
Where:
- Final Value: The current market value of the investment or the price at which it was sold.
- Initial Value: The original cost or purchase price of the investment.
- Income: Any cash flow received during the holding period (dividends, distributions, interest).
Example Calculation
Let's say you purchased a stock for $1,000. After 3 years, the stock price rises, and your holdings are worth $1,250. During those 3 years, you also received $50 in dividends.
- Calculate Total Gain: $1,250 (Final) – $1,000 (Initial) + $50 (Income) = $300 Profit.
- Divide by Initial: $300 / $1,000 = 0.30.
- Convert to Percentage: 0.30 × 100 = 30%.
Your total Rate of Return is 30%.
Annualized Return (CAGR)
If you held the investment for multiple years, the total return rate doesn't tell the whole story. A 30% return over 10 years is much worse than a 30% return over 1 year. To solve this, we calculate the Annualized Return, often called the Compound Annual Growth Rate (CAGR).
Annualized Return = [( (Final Value + Income) / Initial Value ) ^ (1 / Years)] – 1
Using the example above (holding for 3 years), the annualized return would be approximately 9.14% per year, compounding to reach the total 30% growth.
