Try following formula, Hope it will help you.
Unfortunately, you cannot configure a calculated field as you described since calculated fields update their values on updating list items. Thus, the formula cannot include variables other than fields. You can configure a Flow of Workflow that updates a field value periodically in the beginning of each day.
In calculated columns we can refer to other columns, but not other rows. A common solution would be to create a master list that had the names and current number. (so each name would only exist once on this list.

=IF([Col1], 1, 0)
=IF([Col1]=TRUE, 1, 0)
Return the calculated field as Number.
