You have two "proper" choices:To enter transaction as a ReinvDiv, providing the Dividend $ amount and the number of shares and letting Quicken calculate the price/share, orTo enter a DivInc transaction for the dividend $ amount, followed by a Buy Shares amount where you again supply the number of shares and the dividend dollar amount. Both ways are equally right and both ways will lead to a valid calculation of Average Annual Return. The two methods will yield somewhat different values for ROI (Return on Investment) since the ReinvDiv approach does not include the dividend received as shares in the Amount Invested. The price per share should never be treated a zero. The above comments apply without regard to the type of the account - taxable, retirement, IRA, 401k, Roth, regular, 529, etc.
