How to figure out calories?

hi everyone. i was wondering if any of you know if there is a way to figure out how many calories are in a serving of a sertain dish. Is there a website where i can enter all of the ingridients i used for the dish and then it will calculate me how many caloeries are in a serving??? thanks u!

I have watched shows where scientists figure out the calories in foods and it is a very involved process. I couldn't find a website. If you are using ingredients that have a nutrition label on them you can get a close number by calculating the approximate amount of an ingredient that may be in one serving. Keep adding up all of the amounts and you will have a rough number of calories.
