How to Calculate Capital Gains from a Brokerage Statement

Capital gains are just proceeds minus cost basis per lot — but only once your trades are in columns. Here's how to turn a PDF statement into a gains calculation.

Get proceeds and cost basis into rows

Convert the statement so each sale is a row with quantity, proceeds, and cost basis. Once it's tabular, realized gain per lot is a single subtraction, and totals are a sum.

Separate short-term and long-term

With trade dates in a column, you can split holdings by holding period to distinguish short-term from long-term gains — the split that drives your tax rate.

Reconcile across accounts and currencies

Convert statements from every broker into the same layout, including foreign and multi-currency accounts where the currency is preserved, so your total gains picture is complete.

Do it faster with Pro

Pro's batch conversion and Excel output turn a year of statements into one workbook, and the TXF/1099 export takes you from calculation straight to filing.
