How position sizing works

Position sizing answers one question: how many shares can I buy so that if my stop loss hits, I only lose what I planned to lose? The formula is shares = account risk ($) ÷ stop size ($/share), where stop size is the distance between your entry price and your stop price. Risking 0.5% of a $10,000 account ($50) on a trade with a $2 stop size means a 25-share position — no matter how expensive the stock is.

What this tool does

Enter a ticker and Risk Calc streams the live price with a 1-minute candle chart, so you can watch momentum while entering orders at the open. Lock your stop to the low of day and both the stop and your position sizes update in real time as the low moves. Results always show 0.25%, 0.5%, and 1% account-risk tiers side by side, for as many accounts as you trade — name them ("IRA", "Webull"), and sign in with Google to keep balances synced across devices. Free, and works without an account.
