Calories in cheddar cheese.
403 kcal per 100 g.
Cheddar is about a third fat by weight, so it lands around 400 kcal per 100 g — one ounce (28 g), roughly a thick slice, is about 115 kcal. It also carries 23 g of protein per 100 g, which is why cheese is not empty calories, just dense ones.

Energy comes from USDA nutrient 1008. Salt is calculated as sodium × 2.5, with unit conversion to grams. It is not a separately measured salt value.
Preparation
Cheddar is 403 kcal per 100 g with 33.3 g of fat, and melting changes none of it — a cup of melted cheddar is 244 g and 983 kcal because it packs denser, not because it gained anything. Grilling or grating alters the volume a great deal and the density not at all, which is exactly why cheese is the food most often underestimated by eye.
Logging this food
The units diverge wildly: a cup shredded is 113 g and 455 kcal, a cup diced 132 g and 532, a cup melted 244 g and 983. A slice or an ounce is 28 g and about 114. Weigh cheese, or count slices — a cup measurement of cheddar can mean anything between 455 and 983 kcal depending on its state.
Swaps and alternatives
Mozzarella is 299 kcal per 100 g against cheddar's 403, and feta 265 — both save real calories on a sandwich or a pizza. Parmesan is 420, higher per gram, but so strongly flavoured that 5 g does what 20 g of cheddar would, which makes it the better trade in practice.
