You may want to try this >> http://aqadvisor.com/AqAdvisorMarine.php but I feel that it is not perfect, just use as a rough gauge.

In reality there are a number of factors that the number of fishes that can be kept for instance,

• the size of fishes
  
• the number of inverterbates since they also contribute bioload
  
• is it a FOWLR or reef aquarium - FOWLR in general can keep more fishes than reef aquarium
  
• the effectiveness of equipments you have such as protein skimmer
  
• and of course how much effort you are willing to put in for water change, weekly, bi-weekly, etc.
