You can use the 'onvalidation' callback: http://web2py.com/books/default/chapter/29/7#onvalidation
form.process(..., onvalidation=my_form_calculation) You can also define a custom validator for the field to calculate and return the transformed value -- see http://web2py.com/books/default/chapter/29/7#Custom-validators. Finally, if you want to do something with the submitted vars before validation, you can access the vars in request.vars.
