Excel formula with lookup tables for field calculation

The challenge I have is to calculate a new value for one of the field columns of the attribute table of a normal polygon layer.
Precondition: use a formula from an Excel spredsheet which works utilizing lookup tables (data for the formula).

Any ideas for the easiest approach? Maybe do all the calculations outside ARcGIS in a database and then feed the field with the new value?

Thanks,

Sergio
