Where the calories come from
Protein 7% Carbs 91% Fat 2%
Calories computed from USDA per-100 g data (FDC 169097, SR Legacy). raw. The macro split uses general Atwater factors (protein and carbs ≈ 4 cal/g, fat ≈ 9 cal/g) and is approximate.
A medium orange is about 62 calories — computed from USDA’s 47 calories per 100 g for a 131 g fruit. That makes the orange one of the lighter, more filling snacks in the fruit aisle: a whole piece of fruit, juicy and sweet, that covers a full day’s vitamin C for fewer calories than a single cookie. Most of its weight is water and fiber, so it eats like more food than the number implies.
Where an orange’s calories come from
An orange is a carbohydrate fruit, and its calorie split confirms it: about 91% of the calories come from carbohydrate — natural sugar plus fiber — with roughly 7% from its small amount of protein and a trace from fat. The headline nutrient, vitamin C, adds no calories at all; one medium orange just happens to deliver more than a full day’s worth alongside those ~62 carbohydrate-driven calories. So when you eat an orange, you’re spending calories almost entirely on sugar and fiber, and getting a load of vitamin C for free.
Low-calorie, and better whole than juiced
The orange’s calorie story has a practical twist: the whole fruit beats the juice. A medium orange is ~62 calories with about 3 g of fiber to slow digestion and keep you full; an 8 oz glass of orange juice runs closer to 110 calories with the fiber stripped out and the sugar of several oranges concentrated into a few quick sips. Same fruit, very different outcome. For weight management, eating the orange is the move — you get more fiber, more chew, and roughly half the calories of the equivalent juice. It’s a textbook low-energy-density snack, and peeling one by hand naturally paces you, too.
For the macro flip side, see protein in orange — an orange is vitamin C and carbohydrate, and that’s exactly the snack it’s built to be.
Frequently Asked Questions
How many calories are in an orange?
About 62 calories in one medium orange (131 g), based on USDA's 47 calories per 100 g (FDC 169097). A small orange is closer to 45 calories and a large navel can reach 80 — but a typical medium orange is right around 62.
How many calories are in an orange per 100 g or per ounce?
47 calories per 100 g, which is about 13 calories per ounce (28 g). That's a low calorie density — an orange is mostly water and fiber — so even a large one stays light, which is part of why it's such a satisfying low-calorie snack.
Where do the calories in an orange come from?
Almost entirely carbohydrate. Using standard Atwater factors, about 91% of an orange's calories come from carbs (natural sugar and fiber), around 7% from its small amount of protein, and a trace from fat. An orange is a carbohydrate-and-vitamin-C fruit through and through.
Are oranges good for weight loss?
Yes, as snacks go. A medium orange is only about 62 calories with roughly 3 g of fiber and a lot of water, so it's low in calorie density and filling — plus it covers a full day's vitamin C. Eating the whole fruit also slows you down compared with drinking the calories.
How many calories are in an orange versus a glass of orange juice?
A whole medium orange is about 62 calories and brings ~3 g of fiber; an 8 oz glass of orange juice is closer to 110 calories with almost no fiber, because juicing strips it out and concentrates the sugar of several oranges. For fewer calories and more fiber, eat the orange rather than drink it.
When was this data last verified?
2026-06-04, against USDA FoodData Central FDC 169097 (Oranges, raw, all commercial varieties; SR Legacy). We re-verify reference pages periodically and update when the underlying USDA entry changes.
