I am creating payroll system for Indian government employee. I have Some problem in creating dynamic formula and also fetch its result.

Suppose we have basic salary = 5000 and gross salary is 20,000

So gross amount is divided in below category:

TA  = 10% of gross
HRA = Basic + gross * 20 /100
TA ON DA = 
CA = TA * 15 / 100
MA = Basic + TA
PPF = Gross * 5 /100

I want above categories (TA, DA< HRA) should be dynamic and their formula also should be dynamic and when i fetch the formula, it gave me value according to formula.

Note: I don't want to add more modules for category if there is change in future we could change this or add new more category dynamically

Is this should be possible or not ?

Thanks
