Stock Profit Calculator: Calculate Gains & Losses

Knowing your actual profit on a stock trade sounds simple — buy price minus sell price. But fees, stamp duty, currency conversion, and dividend income all affect your real return.

This calculator handles the full picture: purchase cost, sale proceeds, trading fees on both sides, and optional currency conversion for international stocks. It shows your absolute profit, percentage return, and annualised performance.

Use it before selling to model different exit prices, or after selling to record your actual return for tax reporting.
