Estimate dollar and percent P/L from position size, entry, and exit, before fees, for long or short trades.

Use this to sanity-check a closed or planned trade: how much you make or lose in dollars and what that is as a percent of entry. It is a teaching tool, not tax or brokerage advice.

Works for any quoted instrument where you think in shares or units. For options or leveraged products, your broker may show different numbers because of multipliers and fees.
