The number of calories in a 10-piece KFC bargain bucket varies depending on the recipe and cuts of meat included in the bucket. The KFC website includes a nutrition calculator that allows calculation of specific calories. The calorie range for a 10-piece bucket ranges from 1,000 to 5,000.
According to the KFC nutrition calculator, the number of calories varies widely for different pieces of chicken.
