📈Stock Profit Calculator

About this tool

Enter the number of shares, buy and sell prices, commissions on each side, and the dates you bought and sold. You'll see the profit or loss, the percentage return, the annualised return over the holding period, the break-even price after costs and the sell price needed to hit a target return.

Working out a trade's real return

Profit is what you received from selling minus everything it cost to buy: (shares × sell price − selling commission) − (shares × buy price + buying commission). The return is that profit divided by the total cost. For example, buying 100 shares at 42.50 with a 5 commission costs 4,255. Selling at 51.20 with another 5 commission brings in 5,115, a profit of 860 and a 20.21% return. Comparing returns over different lengths of time needs an annualised figure. 20.21% over 462 days is equivalent to about 15.65% a year, calculated as (proceeds ÷ cost)^(365 ÷ days) − 1. The break-even price, 42.60 here, is the sell price that exactly recovers the purchase and both commissions. The target price shows where to set a limit order for the return you want: 53.24 for 25%. The same arithmetic works for ETFs, funds and crypto in any currency. Honest limits: dividends you received, currency conversion costs, stamp duty or transaction taxes and capital gains tax aren't included, and past performance doesn't predict future returns. This isn't investment advice. The stock average calculator, the capital gains tax calculator and the dividend calculator are related.
