Calories computed from USDA per-100 g data (FDC 171688, SR Legacy). raw, with skin. The macro split uses general Atwater factors (protein and carbs ≈ 4 cal/g, fat ≈ 9 cal/g) and is approximate.
A medium apple comes to about 95 calories — built from USDA’s low 52 calories per 100 g across a 182 g fruit. That’s the number behind the apple’s reputation as a sensible snack: a whole, satisfying piece of fruit you can hold in one hand for under 100 calories. Most of that bulk is water and fiber, which is why an apple feels like more food than its calorie count suggests.
Where an apple’s calories come from
An apple is carbohydrate and water, and its calorie split says so: about 95% of the calories come from carbohydrate — natural sugar plus a healthy dose of fiber — with only a sliver from its trace protein and fat. There’s nothing else to it. That carbohydrate, though, arrives wrapped in about 4.4 g of fiber in a medium apple, much of it pectin, which slows digestion and is why an apple satisfies rather than spikes the way a sugary drink with the same calories would.
A low-density snack that fills you up
The apple’s real edge is calorie density, or rather the lack of it. At 52 calories per 100 g it’s one of the lighter fruits you can eat, so a medium apple delivers genuine volume, crunch, and sweetness for ~95 calories. That makes it a smart pick when you want to feel full without spending many calories — the textbook low-energy-density snack. The practical tip is simply to eat it whole, skin on: the skin holds much of the fiber, vitamin C, and antioxidants, and peeling it trims almost no calories while costing you the best part. An apple paired with a protein — string cheese, a few nuts, a spoon of peanut butter — becomes a balanced mini-meal for not many more calories.
For the macro flip side, see protein in apple — an apple is a fiber-rich carb, and that’s exactly the snack it’s meant to be.
Frequently Asked Questions
How many calories are in an apple?
About 95 calories in one medium apple with skin (182 g), based on USDA's 52 calories per 100 g (FDC 171688). A small apple is closer to 75 calories and a large one around 115 — but the everyday 'an apple is about 95 calories' figure is right for a medium one.
How many calories are in an apple per 100 g or per ounce?
52 calories per 100 g, which is about 15 calories per ounce (28 g). That's a low calorie density — an apple is mostly water and fiber — which is exactly why a whole medium one is filling for under 100 calories.
Where do the calories in an apple come from?
Almost all carbohydrate. Using standard Atwater factors, about 95% of an apple's calories come from carbs (natural sugar plus fiber), with only a couple of percent each from its trace protein and fat. An apple is essentially a carbohydrate-and-water snack.
Are apples good for weight loss?
They're one of the better snack choices for it. A medium apple is about 95 calories with roughly 4.4 g of fiber and a lot of water, so it's low in calorie density and genuinely filling — you get real chew and sweetness for the calorie cost. Eat it with the skin on to keep the fiber.
How many calories are in an apple without the skin?
Slightly fewer and less nutritious — peeling removes some fiber and antioxidants but barely changes the calories, which still sit around 90 for a medium apple. The calorie difference isn't worth losing the skin's fiber and vitamin C, so eat it whole when you can.
