You really have to be careful when using nutrition calculators to determine the number of calories (and other info) in a serving of a recipe. It's important how you enter the ingredients in a recipe.
For example, a recipe calls for '1 Lb. Ground Beef'. It's most likely the nutrition calculator will give you the number of calories in a pound of raw ground beef. What you really need to know is the number of calories after a pound of raw ground beef has been cooked! That will be a lot less after the fat and juices have been cooked off.
So now you need to know 'If I start with a pound of raw ground beef, how much will the cooked drained beef weigh?', so you can enter that amount into your recipe. That will work if you know the weight and your nutrition calculator has an item for '1 pound of raw ground beef, cooked and drained'.
The USDA has an online/downloadable Nutrition Database that helps you with this. It will give you info on a pound of raw ground beef by fat percentages, how much it will weigh after it's cooked, etc. Armed with this info, you can use cookbook software to give you what you need.
