Impact of creating calculated fields in Workday

what is the impact of making calculated fields in Workday Will it make Workday slower, if this is slower how we are able to keep away from to make a few modifications particularly for integration ?

Is it higher to have a record based totally calculated fields. If sure, then will it impact on the document only ?

Is Workday doesn’t calculated field OR they have got any special recommendation in this ? https://goo.gl/z1dfCJ
