How to figure calories in a meal made at home

Hello! I made chicken salad with light mayo, boneless skinless chicken breast and 3 hard boiled eggs. How do I figure out the serving size and calories per serving? When I was on wight watchers they had a reciept builder, are there any web sites out there that can help me with this?

Thanks in advance!
