It would be nice if a calculated field updated immediately as data is entered in a screen layout. For example, I created a field for 'standard hours of work per week' and a field for 'wage'. I then created a calculated field that multiplied the two fields and multiplied this by 52 to get an annual income.
The 'annual income' field only updates after I move to another contact. It would be great if it updated in real time so the user can confirm the correct amount.
