CommishCalc 1.0 - CommishCalc calculates commissions on the purchase or sale of stocks or options made through the Charles Schwab brokerage firm. The commissions calculated are based upon a chart published by Charles Schwab Co. on May 21, 1991 and was still current as of December 20, 1993. Much effort has been made to make the calculations accurate but neither the author of this application nor Charles Schwab Co. will be held responsible for miscalculations of commissions.
