Stock Market Calculators
Read a stock by its numbers: valuation ratios like P/E, dividend yield, and the risk and return behind a whole portfolio.
Sort by
- Stock Profit / Loss Calculator Calculate real profit or loss on a stock trade after brokerage, charges, and capital-gains tax. Enter buy price, sell price, and quantity to see net profit, return, breakeven sell price, annualized return, and target-price needs.
- Stock Return Calculator Calculate total and annualized stock return from buy price, sell or current price, and holding period. Add dividends, taxes, inflation, and a benchmark to see net return, real return, CAGR, and whether you beat the market.
- Stock Average Calculator Find your weighted-average cost after buying a stock at different prices. Add each purchase price and quantity to see average cost, total shares, total invested, unrealized profit or loss, and shares needed to reach a target average.
- Portfolio Return Calculator Measure total portfolio return across holdings. Enter invested amount and current value for each position to see total gain, return, annualized CAGR, holding weights, contribution to return, benchmark comparison, and allocation chart.
- P/E Ratio Calculator Calculate a stock’s P/E ratio from price and EPS, or market cap and net income. See earnings yield, forward P/E, PEG, and comparison with an industry average to judge whether valuation looks rich or cheap.
- PEG Ratio Calculator Calculate the PEG ratio by dividing P/E by earnings growth. Enter P/E or price and EPS, add growth rate and optional dividend yield for PEGY, then test how sensitive the valuation is to growth assumptions.
- Price-to-Book Ratio Calculator Calculate price-to-book from stock price and book value per share, or market cap and total equity. Add intangibles to get price-to-tangible-book and compare market value with the company’s accounting net worth.
- Price-to-Sales Ratio Calculator Calculate price-to-sales for companies where revenue matters more than earnings. Enter market cap and sales, or price and sales per share, then add debt and cash for EV/Sales and growth to see how the multiple changes.
- Earnings Per Share (EPS) Calculator Calculate basic and diluted earnings per share from net income, preferred dividends, shares outstanding, and dilutive securities. See how much profit belongs to each share and the more conservative EPS used in valuation.
- Market Cap Calculator Calculate market capitalization from share price and shares outstanding. See the company size category, enterprise value after debt and cash, float-adjusted cap, fully diluted cap, and compare multiple companies side by side.
- Dividend Yield Calculator Calculate dividend yield from dividend per share and stock price. Add purchase price for yield on cost, dividend growth for forward yield, tax for net yield, and payout frequency to annualize quarterly or half-yearly dividends.
- Dividend Income Calculator Estimate dividend income from shares owned and dividend per share. See annual and monthly income, project dividend growth over time, model reinvestment with DRIP, or work backwards from a target income to the shares or capital needed.
- Dividend Reinvestment Calculator Compare reinvesting dividends with taking them as cash. Enter starting shares, dividend yield, growth, price appreciation, tax, fees, and contributions to see the extra value DRIP compounding can create over time.
- Dividend Discount Model Calculator Value a dividend-paying stock from the present value of future dividends. Use the Gordon Growth model for steady growth or a two-stage model for faster growth now and slower growth later, then compare intrinsic value with market price.
- Beta Calculator Calculate a stock’s beta, its movement relative to the market. Paste stock and market returns to compute beta as the regression slope, with alpha and R², or enter covariance and market variance directly.
- Alpha Calculator Calculate Jensen’s alpha: the return earned above what CAPM predicts for the risk taken. Enter actual return, risk-free rate, beta, and market return — or expected return directly — to see whether a stock, fund, or portfolio outperformed its benchmark.
- CAPM Calculator Use CAPM to estimate expected return or cost of equity from the risk-free rate, beta, and market return. See the risk premium, Security Market Line position, and alpha if you add the actual return.
- Sharpe Ratio Calculator Calculate Sharpe ratio to compare risk-adjusted returns. Enter return, risk-free rate, and volatility, compare multiple portfolios, or paste return data to compute mean return, volatility, Sharpe ratio, and Sortino ratio.
- Sortino Ratio Calculator Calculate Sortino ratio, a risk-adjusted return measure that counts only downside volatility. Enter return, target return, and downside deviation, paste a returns series, or compare portfolios with the Sharpe ratio shown alongside.
- Volatility Calculator Measure investment volatility from returns or prices. Paste a return series, or prices to derive returns, and see periodic and annualized volatility, variance, downside deviation, and the inputs used for Sharpe and Sortino ratios.
- Portfolio Allocation Calculator Set a target portfolio allocation across assets or holdings. Enter total investment and target weights to see how much goes into each, then add current values to find gaps and what to top up.
- Portfolio Rebalancing Calculator Rebalance a drifted portfolio back to target weights. Enter current values and target allocations to see the buys and sells required, or use contribution-only mode to direct new money toward underweight holdings.
Profit & returns 4
- Portfolio Return Calculator Measure total portfolio return across holdings. Enter invested amount and current value for each position to see total gain, return, annualized CAGR, holding weights, contribution to return, benchmark comparison, and allocation chart.
