Capital Gains Yield Calculator

The calculation relies on two fundamental steps: finding the absolute dollar increase in value, and then expressing that increase as a fraction of the initial purchase price. First, you subtract the initial purchase price from the current market price to find the total capital gains: capital_gains = current_price - bought_price. Next, you divide those capital gains by the bought price to find the yield: capital_gains_yield = capital_gains / bought_price. Multiplying the final decimal by 100 converts the result into a standard percentage.

Imagine you purchase shares of a technology company for an initial bought price of $50 per share. Over the course of two years, market demand surges, and the current price climbs to $65 per share. To find the capital gains, subtract the purchase price from the current price: $65 - $50 = $15 gain per share. Next, divide that $15 gain by the original bought price of $50: $15 / $50 = 0.30. Converting this decimal to a percentage yields a capital gains yield of 30%, demonstrating robust asset appreciation over the holding period.

Always remember that capital gains yield measures unrealized or realized price growth alone and does not account for dividends, interest payments, or transaction fees. When evaluating investments for tax purposes, distinguish carefully between short-term capital gains (assets held for one year or less) and long-term capital gains, as tax rates often vary significantly between the two holding periods. Finally, use this metric alongside total return calculators to get a comprehensive picture of your overall investment performance.
