When selling stock, Stock Calculator can determine the net profit amount and total return percentage, or the per share selling price.

Stock Calculator can optionally include flat rate, percentage, per share, or custom commissions in the calculations. The custom option allows advanced flexibility in defining commission rates. User-defined taxes on the net profit can also be deducted.

Calculations can be saved as documents and multiple calculation windows can be open simultaneously. An optional details area is available to show the calculation line items and subtotals, and can be printed for future reference.

Old-style stock fraction calculations are also supported.
