This calculator assumes the dollar amount you enter as your original cost basis per share is valid and does not compare that dollar amount with the range of market prices that existed on the date you purchased your shares. This calculator purely serves to help you determine your adjusted original cost basis per share, for the major events affecting your stock, using the dollar amount you entered as your unadjusted original basis per share.
