Definition of Annual Rate of Return

Under Canada Revenue Agency (CRA) guidelines, the annual rate of return is crucial for portfolio management, retirement planning, and tax reporting.

For example, if a Toronto investor buys a stock for $10,000 and sells it for $11,500 after one year, the annual rate of return is 15%.

Purpose of the Annual Rate of Return in Investing

Investors and businesses use the annual rate of return to:

1. Measure Investment Performance – Assess the profitability of stocks, bonds, and real estate.
2. Compare Different Investments – Evaluate returns across asset classes like stocks vs. GICs.
3. Track Portfolio Growth – Determine whether investments are meeting financial goals.
4. Assess Risk vs. Return – Higher returns often come with greater volatility.
5. Calculate Taxable Gains – Ensuring compliance with CRA capital gains tax rules.

How to Calculate the Annual Rate of Return

The formula for the annual rate of return is:

Annual Rate of Return = (Ending Value − Beginning Value + Income Received / Beginning Value) × 100

Example Calculation

A Canadian investor purchases a mutual fund for $20,000 and sells it one year later for $23,000, receiving $500 in dividends.

Annual Rate of Return = (23,000 − 20,000 + 500 / 20,000) × 100 = (3,500 / 20,000) × 100 = 17.5%

Considering both price appreciation and dividends, the investor’s annual return is 17.5%.

Types of Annual Rate of Return

1. Nominal vs. Real Rate of Return

• Nominal Return – The raw percentage return before inflation adjustment.
• Real Return – The return adjusted for inflation to reflect actual purchasing power.

Example: If a stock earns 8% annually, but inflation is 2%, the real return is 6%.

2. Compound Annual Growth Rate (CAGR)

CAGR measures the average annual return over multiple years, smoothing out volatility.

Formula:

CAGR = (Beginning Value / Ending Value)^(1/n) - 1

Where n is the number of years.

Example: A $10,000 investment grows to $15,000 in 5 years.

CAGR = (15,000 / 10,000)^(⅕) − 1 = 8.45%

3. Expected vs. Historical Return

• Expected Return – A projected future return based on historical performance and market conditions.
• Historical Return – The actual past performance of an investment.

Example: The S&P/TSX Composite Index has a historical annual return of ~7% over the past 50 years.

Annual Rate of Return vs. Annual Percentage Yield (APY)

Category	Annual Rate of Return	Annual Percentage Yield (APY)
Definition	Measures investment gains/losses	Measures compound interest earned
Used For	Stocks, bonds, real estate	Savings accounts, GICs, and fixed income
Includes Compounding?	No	Yes

For example, a savings account offers a 5% APY, meaning interest compounds over time, while a stock's return is based on price changes and dividends.
