Trade Snapshot
The Stock Profit Calculator lets you instantly compute the profit or loss on any stock trade. Enter your buy price, sell price, number of shares, and brokerage commissions to see your exact net gain, return on investment percentage, and per-share profit — all after fees are deducted. Perfect for individual traders, long-term investors, and anyone tracking portfolio performance.
Stock profit equals your total proceeds (shares × sell price, minus sell commission) minus your total cost basis (shares × buy price, plus buy commission). The return percentage is profit divided by total cost, expressed as a percentage.
Yes — commissions and fees directly reduce your net profit. A $4.95 buy and $4.95 sell commission on a small trade can meaningfully change your actual return. This calculator supports both flat-fee and percentage-based commission structures.
Fee drag is the difference between your gross profit (ignoring fees) and your net profit (after fees). It shows exactly how much of your potential gain is consumed by trading commissions, helping you evaluate whether a trade is worthwhile after costs.
Yes — the core math applies to any security traded at a per-unit price. Enter the per-share (or per-unit) buy and sell prices, the number of units, and any applicable commissions. The calculator will handle the rest.
