An equity rollforward shows how the equity accounts changed from one month end to the other. So on a workbook sheet at top row put the titles of your equity accounts - usually common stock, surplus, retained earnings, other comprehensive income.
Next row down enter the prior month balances.
For this example we follow the retained earnings account. So you would have a row labeled "net income" and there you put the income for the month in the column that holds "retained earnings" Now in a lower row you show the sum of last months retained earnings balance plus this months net income. The total should equal the current month's retained earnings. And that is a rollforward. Now just do the same for all the other elements of your equity and you are there!. To get fancy add a column showing the number of common shares and how that number changes if you add or retire common stock.
Good luck!
