Month Limit will show you a forecast for the month's expenses and the spending rate recommended. To do it, it uses your data and also automatically determines the current day and the number of days in the current month.
After you create a record in the table, you will only have to specify data for the current day. It is quite easy to do it. Double-click the corresponding record in the table, type the new value and press Enter. You do not have to select this field, the current value is automatically selected in the dialog box and the new value replaces the old one when you start entering it.
