Ctc Break-up In Ms-excel - Xls Download

I am working on subject in order to revise the existing CTC structure. In doing so, the special allowance which balances the CTC fitment is a figure which is a component of Monthly Gross Salary and on which Employer ESIC Contribution is dependent. I need to work out a formula
\"@IF(....)\" for the Special Allowance cell to complete this fitment appropriately.
Please assist.
