Stock Return Calculator
Calculate the total percentage return on a stock position by combining capital gains and dividends received. Use it to evaluate how well a specific investment has performed.
About this calculator
Total stock return captures both the price appreciation of your shares and any dividend income received. The formula is: Total Return (%) = ((currentPrice − purchasePrice) × shares + dividends) / (purchasePrice × shares) × 100. The numerator represents your total profit: capital gain per share times the number of shares, plus all dividends collected. The denominator is your total cost basis — what you originally paid. Expressing the result as a percentage lets you compare returns across investments of different sizes. Note that this formula does not annualize the return; to compare investments held for different lengths of time, you would also want to calculate the compound annual growth rate (CAGR).
How to use
You buy 50 shares at $40 each and later they trade at $55. During the holding period you received $150 in total dividends. Cost basis = 50 × $40 = $2,000. Capital gain = (55 − 40) × 50 = $750. Total profit = $750 + $150 = $900. Total Return = $900 / $2,000 × 100 = 45%. Your investment of $2,000 generated a 45% total return. Without the dividends, capital-gains-only return would have been 37.5%, showing how dividends meaningfully boost overall performance.
Frequently asked questions
What is the difference between total return and capital gains return on a stock?
Capital gains return measures only the price change of a stock — how much the share price rose or fell relative to your purchase price. Total return adds dividend income on top of that, giving a more complete picture of investment performance. For income-focused stocks like utilities or REITs, dividends can represent the majority of total return, so ignoring them would severely understate how well the investment performed.
How do dividends affect the total return percentage on a stock investment?
Dividends increase your total return because they represent cash received in addition to any price appreciation. In this calculator they are added directly to your capital gain in the numerator. Over long holding periods, reinvested dividends have historically accounted for a large portion of total equity market returns — some studies suggest over 40% of S&P 500 total return since 1930 came from dividends. Even modest dividend yields significantly compound your wealth if reinvested.
Why doesn't total return tell me everything I need to know about a stock investment?
Total return ignores the time dimension — a 45% return over 10 years is far less impressive than the same return over 2 years. It also doesn't account for inflation, taxes on dividends and capital gains, or the opportunity cost of capital. To compare investments fairly, you should also calculate the annualized return (CAGR) and consider after-tax returns. Additionally, total return doesn't measure risk, so a high-return investment that was extremely volatile may not have been the best choice for your portfolio.
