Calculate capital gains yield and investment returns

About the Capital Gains Yield Calculator

The Capital Gains Yield (CGY) Calculator is an essential tool for investors and financial analysts who need to isolate the price appreciation component of an investment's total return. Unlike total return, which combines capital growth with income streams like dividends or interest, the capital gains yield focuses strictly on the change in the market value of an asset relative to its original purchase price. This metric is particularly useful when evaluating growth stocks that do not pay dividends, or when comparing the price volatility of various assets within a portfolio.

Using this tool allows you to determine how much profit or loss you have generated based solely on market movements. It is a fundamental calculation used in the Dividend Discount Model (DDM) and capital budgeting to forecast future returns or assess historical performance. Whether you are tracking real estate, stocks, or collectible commodities, understanding the CGY helps in making informed decisions about whether to hold, sell, or rebalance your positions based on price performance alone.

Formula

Capital Gains Yield = ((Current Price - Purchase Price) / Purchase Price) * 100

The formula calculates the percentage change in the market price of an investment. 'Current Price' represents the market value at the time of calculation or the sale price, while 'Purchase Price' is the original cost basis (acquisition cost) of the asset. The result is expressed as a percentage to show the relative growth or decline of the principal investment.

Worked examples

Example 1: An investor purchases 100 shares of a company at $80 per share and the price later rises to $100 per share.

Step 1: Subtract purchase price from current price ($100 - $80 = $20).
Step 2: Divide the gain by the purchase price ($20 / $80 = 0.25).
Step 3: Multiply by 100 to get the percentage (0.25 * 100 = 25%).

Result: 25% capital gains yield. The investor earned a quarter of their initial investment through price appreciation.

Example 2: A trader buys a cryptocurrency for $50,000, but the market value drops to $45,000.

Step 1: Subtract purchase price from current price ($45,000 - $50,000 = -$5,000).
Step 2: Divide the loss by the purchase price (-$5,000 / $50,000 = -0.10).
Step 3: Multiply by 100 to get the percentage (-0.10 * 100 = -10%).

Result: -10% capital gains yield. This indicates a capital loss on the principal investment.

Common use cases

Evaluating the performance of a non-dividend paying technology stock over a fiscal quarter.
Determining the percentage increase in the value of a residential property since its purchase date.
Comparing the price appreciation of gold versus silver over a specific market cycle.
Calculating one of the two components required to find the total expected return in the Gordon Growth Model.

Pitfalls and limitations

The calculation does not account for brokerage fees or commissions paid during the buy and sell process.
It ignores the impact of inflation, which can erode the real purchasing power of the gains.
Capital gains yield does not reflect the tax liabilities incurred upon the sale of the asset.
Solely relying on CGY might lead to ignoring high-dividend yield stocks that offer better total returns despite lower price growth.

Frequently asked questions

can capital gains yield be negative

Yes, capital gains yield can be negative if the current price or sale price of the asset is lower than the amount you originally paid for it, representing a capital loss.

difference between capital gains yield and total return

Capital gains yield only measures the price appreciation of the asset, while total return includes both the price change and any income generated, such as dividends or interest.

does capital gains yield include dividends

Dividends are excluded from the capital gains yield calculation because it specifically isolates the profit or loss resulting solely from market price fluctuations.

is capital gains yield the same as stock growth rate

While related to the growth rate in the Gordon Growth Model, CGY specifically looks at historical or expected price changes, whereas dividend yield looks at the cash flow return relative to price.

how to calculate annualized capital gains yield for multi year investments

To calculate the annual CGY for an asset held over several years, you should find the total percentage change and then use the geometric mean or CAGR formula to annualize the return.
