I want to calculate an interest on a fee, that is if a client has not paid full amount of fee before the 15th of the month an interest of 10% should added to the amount to be paid
my cells are Amount payable Column B Amount paid Column c upstanding amount Column D Date for payment Column E penalty to be Paid 10% Column
How do i calculate this ?
i tried the below formula and had Err:509
=IF(E2=TODAY()>15, "Overdue" "B2*10/100",)
what i was trying to accomplish is .If today is on the 15th or the date is pass 15th of the month and there is upstanding amount to be paid attract a penalty of 10%
