Trading & Investing Calculators
Free, practical calculators for studying the markets — size a position by risk, weigh risk against reward, tally a trade's profit or loss, gauge dividend yield, and project compounding and returns.
Position Size Calculator
Work out how many shares a fixed-fractional risk model implies from your account balance, risk-per-trade percentage, entry, and stop-loss — with the dollar risk, per-share risk, and position value
Risk/Reward Ratio Calculator
Turn an entry, stop-loss, and target price into a reward-to-risk ratio, and see the break-even win rate that ratio would need over many trades — pure arithmetic, no signals
Stock Profit Calculator
Work out the profit or loss on a share trade from the share count, buy price, sell price, and an optional flat fee — total cost, total proceeds, net profit, and percentage return
Dividend Yield Calculator
Compute a stock's dividend yield from its annual dividend per share and price, and project the annual income for a given number of shares — a like-for-like income comparison
Compound Interest Calculator
Project the future value of a lump sum plus optional regular contributions from a rate, term, and compounding frequency — the future value, total contributed, and interest earned
ROI Calculator
Measure the return on an investment from its initial cost and final value — net profit and total ROI, plus the annualized (CAGR) return when you add a holding period
