# Combining Formulas For Percent Complete Column

Options
✭✭✭

How can I combine two formulas together. The purpose of these formulas is to calculate the percent complete based on the start and finish date. If the start date is blank i want it to return 0% but if we have the start and finish date filled in then it will calculate that percentage.

First formula: =IF(ISBLANK([Estimated Start]@row), 0)

Second Formula: =(TODAY() - [Estimated Start]@row) / ([Estimated Finish]@row - [Estimated Start]@row)

Thank you in advance for any help.

You would drop the second formula into the 3rd position within the IF statement.

=IF(argument, value if true, value if false)
