π Stock Return Calculator
What your trade actually earned, dividends included.
Total profit
Estimates for planning only, not financial advice.
Buy 100 shares at $50, sell at $75 three years later, and collect $200 in dividends: your profit is $2,700, a 54 percent total return, which annualizes to 15.48 percent a year. The price chart shows a 50 percent gain; the dividends and the time it took are what turn a good trade into a measured return.
How to Use This Calculator
Enter buy and sell prices, share count, total dividends received while holding, and the holding period in years. The calculator gives profit, total return, and the annualized (compounded) return that lets you compare this trade against anything else.
Enter the actual buy and sell prices per share, after any splits. Your brokerage cost-basis statement has these.
Add all dividends received. Investors routinely forget these and understate returns by 1 to 2 percent a year.
Enter the holding period and compare the annualized figure, not the total, against your other options.
The Formula
Total return answers "how much did I make." Annualized answers "how fast," using geometric compounding, the same math as CAGR. A 54 percent gain over 3 years is not 18 percent a year; it is 15.48 percent, because compounding works in reverse too. This calculator ignores commissions and taxes for clarity; subtract both for your true net, and note that dividends were taxed along the way even if you reinvested them.
Worked Example
100 shares bought at $50 ($5,000 cost), sold at $75 ($7,500), $200 in dividends, held 3 years. Profit: (75 - 50) x 100 + 200 = $2,700. Total return: 2,700 / 5,000 = 54.0 percent. Annualized: (7,700 / 5,000)^(1/3) - 1 = 1.54^0.333 - 1 = 15.48 percent per year. Without the dividends the annualized return would be 14.47 percent, a full point lower. That point is the dividend yield doing its quiet work.
Why Annualized Beats Total Return
Total return cannot compare trades of different lengths. A 40 percent gain in 2 years (18.3 percent annualized) beats a 60 percent gain in 5 years (9.9 percent annualized), and the total-return ranking gets it backwards. Annualized return is the common denominator: it converts every trade into a per-year speed. Compare it against the S&P 500's long-run ~10 percent, against your mortgage rate if you are choosing between investing and prepaying, and against the compound interest math of just holding an index fund.
Dividends: The Forgotten Half (Well, Third)
Price charts lie by omission: they exclude dividends. Over the last century, dividends and their reinvestment supplied roughly a third of the US stock market's total return. A stock that went "nowhere" from $50 to $52 over five years while paying a 4 percent yield actually returned about 22 percent total. Always compute total return, price plus dividends, or you will systematically underrate boring dividend payers and overrate glamorous non-payers. Our ROI calculator handles the same math for non-stock investments.
Taxes Change the Ranking
Hold over a year and gains are long-term, taxed at 0, 15, or 20 percent for most taxpayers versus ordinary rates on short-term trades. Qualified dividends get the same favorable rates. A 15.48 percent pre-tax annualized return held long-term at a 15 percent capital gains rate is about 13.2 percent after tax; the same trade flipped in 11 months could keep barely 10 percent after tax at a 32 percent marginal rate. The holding period field is not just for math, it is a tax decision.
Reading a Stock Quote
A quote is a dashboard, not just a price. The bid and ask show what buyers and sellers are offering right now; the spread between them is your round-trip transaction cost, tiny for Apple, wide for thinly traded small caps. Volume tells you whether the price move means anything: a 5 percent jump on triple average volume is conviction, on half average volume is noise. Market cap (price times shares outstanding) sorts the universe: mega cap above $200 billion, large cap $10-200 billion, mid cap $2-10 billion, small cap below $2 billion.
The valuation cluster sits beside the price: P/E (price per dollar of earnings), forward P/E (per dollar of expected earnings), and dividend yield. A P/E of 25 means you pay $25 for each $1 of annual earnings, or equivalently expect a 4 percent earnings yield. None of these numbers is a buy signal alone; together they answer three questions: what does it cost to trade, how seriously should I take the move, and what am I paying for the earnings stream.
Price Is What You Pay, Value Is the Question
A stock calculator tells you what a return was; it cannot tell you what it will be. Use the math here to measure past performance honestly, after taxes and inflation, then apply the harder judgment of whether the business behind the ticker deserves your next dollar. The investors who compound for decades share one habit: they check the price daily and the business quarterly, never the reverse.

Frequently Asked Questions
How do I calculate profit on a stock trade?
Subtract: (sell price minus buy price) times shares, plus dividends received. Buying 100 shares at $50 and selling at $75 with $200 in dividends gives (75-50) x 100 + 200 = $2,700 profit. Subtract commissions and account for taxes for the true net figure.
What is the difference between total return and annualized return?
Total return is profit divided by cost, the whole gain. Annualized return converts it to a per-year compounded rate: (proceeds/cost)^(1/years) - 1. A 54 percent total gain over 3 years annualizes to 15.48 percent, not 18 percent, because of compounding.
Should dividends be included in stock returns?
Always. Total return means price appreciation plus dividends, and dividends have supplied roughly a third of long-run US market returns. Price-only charts understate real performance, especially for high-yield stocks held for years. When comparing two investments, compare total returns over identical periods with dividends reinvested, or the higher yielder will look unfairly worse.
What is a good annualized stock return?
The S&P 500 has returned about 10 percent annualized before inflation over long periods, roughly 7 percent after inflation. Beating 10 percent over a decade is genuinely good; doing it over one lucky year is noise. Compare against the index over the same period, not against headlines.
How do stock splits affect my return calculation?
They do not, as long as you adjust. In a 4-for-1 split, divide your buy price by 4 and multiply shares by 4; cost basis is unchanged. Brokerage statements usually adjust automatically. Our stock split calculator does the conversion if your records predate the split.
Do I subtract commissions from stock profit?
Yes for your true net. Commissions are small at most modern brokerages but not zero everywhere, and bid-ask spreads cost a little on every trade. Frequent traders should also weigh how turnover drags the annualized figure down. For tax purposes, commissions add to your cost basis (reducing taxable gain), while spreads are simply lost to the market and never recoverable.
How are stock profits taxed?
Gains on shares held over a year are long-term, taxed at 0, 15, or 20 percent for most taxpayers. Gains on shorter holds are taxed as ordinary income. Qualified dividends get the long-term rates. State taxes apply on top in most states.
What is CAGR and is it the same as annualized return?
Yes. CAGR (compound annual growth rate) is exactly this annualized formula: (end/start)^(1/years) - 1. It smooths a bumpy ride into one steady yearly rate, which is useful for comparison but hides the volatility you lived through. Two investments can share a 10 percent CAGR while one never dropped and the other fell 40 percent twice; always check maximum drawdown alongside CAGR.
Can annualized return be negative?
Yes, when proceeds are below cost. Losing 20 percent over 2 years annualizes to about -10.6 percent per year, which is worse than -10 percent per year sounds because the math is geometric. The calculator handles losses the same way as gains.
Why does holding period matter so much?
Because compounding needs time, and because tax treatment changes at one year. A 15 percent gain in 6 months annualizes to 32 percent; the same gain over 5 years is under 3 percent a year. Always annualize before comparing two investments.
