Calculate capital gains yield from purchase price and current market price.
Capital Gains Yield Calculator
Free online capital gains yield calculator to measure the price-only return earned on an investment from purchase price to current market price. This calculator is useful for investors, students, portfolio reviewers, and anyone who wants a fast way to separate price appreciation from income return. Capital gains yield focuses only on the increase or decrease in price. That makes it useful when analyzing stocks, funds, or other assets where you want to understand how much of the return came from price movement alone rather than dividends, interest, or other cash distributions.
This page uses two market-price inputs. Purchase price means the price at which the security or asset was originally bought. Current price means the present market price. Once those values are entered, the calculator shows capital gains yield, gain per share, price growth multiple, and current value per $100 purchase price. These outputs make the result easier to read because some users want the percentage return, others want the actual price gain, and others want a simple multiple or normalized current value measure for comparison across securities.
The formula of capital gains yield
Gain per share = Current price – Purchase price
Capital gains yield = (Current price – Purchase price) / Purchase price
Price growth multiple = Current price / Purchase price
Current value per $100 purchase price = Price growth multiple x 100
Here purchase price means the original acquisition price, current price means the latest market value used for the comparison, gain per share means the price increase or decrease in money terms, capital gains yield means the percentage price return relative to the purchase price, price growth multiple means how many times the original price became, and current value per $100 purchase price shows what each $100 of original price is worth now.
Solved Example
Example 1: Find the capital gains yield if the purchase price is $100 and the current price is $125.
Solve: Gain per share = 125 – 100 = $25
Capital gains yield = 25 / 100 = 0.25 = 25%
Price growth multiple = 125 / 100 = 1.25
Current value per $100 purchase price = 1.25 x 100 = $125
Example 2: Find the result if the purchase price is $48 and the current price is $60.
Solve: Gain per share = 60 – 48 = $12
Capital gains yield = 12 / 48 = 0.25 = 25%
Price growth multiple = 60 / 48 = 1.25
Current value per $100 purchase price = 1.25 x 100 = $125
Example 3: Find the result if the purchase price is $80 and the current price is $68.
Solve: Gain per share = 68 – 80 = -$12
Capital gains yield = -12 / 80 = -0.15 = -15%
Price growth multiple = 68 / 80 = 0.85
Current value per $100 purchase price = 0.85 x 100 = $85

How to use this capital gains yield calculator
Enter the purchase price in the proper input field. After that, enter the current market price of the same investment or asset. Then click the calculate button. The calculator will show capital gains yield, gain per share, price growth multiple, and current value per $100 purchase price in the result box.
This calculator is useful when you want to isolate the price-change portion of return. For example, a stock may produce total return from both dividends and price appreciation, but capital gains yield shows only the price side. That makes it helpful for comparing growth-oriented investments, reviewing trading outcomes, and separating market-price performance from income return. Looking at gain per share beside the yield also makes the result easier to explain in both percentage and money terms.
When using the result, remember that capital gains yield does not include dividends, interest, or other distributions. It is therefore not the same as total return. It also does not account for taxes, trading costs, or the time period between purchase and current price. Even so, capital gains yield remains one of the clearest quick measures of price-only investment performance. This calculator gives a fast numerical view that supports portfolio review, stock comparison, return analysis, and finance learning.
