Currently only half supported. By this I mean we can do math on fields and aggregate them per bucket. Basically sum(div(sold_products,products)), assuming products and sold_products exist on each document. What we can't do yet is do math on aggregations: div(sum(sold_products),sum(products)) If the former works for you, simply place that in a facet block within a parent facet (like your range facet). http://yonik.com/solr-facet-functions/ -Yonik
