How many carbs are in an apple?
A medium apple (182 g) of an apple has about 25.1 g of carbohydrate, of which roughly 20.7 g is net carbs (total minus 4.4 g of fiber). Per 100 g, an apple has 13.8 g of carbohydrate. About 4 g of that is fiber, most of it in the skin, and roughly 19 g is natural sugar. The fiber slows how quickly the sugar reaches your blood, which is why a whole apple behaves very differently from apple juice.

The carbs in an apple, in context
The skin is doing quiet work. Peeling an apple removes much of the 4 g of fiber, which is exactly the part that blunts the sugar spike, so a peeled apple is a faster carbohydrate than a whole one. Juice takes this further: it strips the fiber entirely and concentrates the sugar, so a glass of apple juice hits blood sugar far harder than the fruit it came from. At roughly 21 g of net carbs, a medium apple is too much for strict keto but a reasonable choice on most lower-carb plans.
Carbs by portion
Grocery apples run large. A small apple (149 g) has about 21 g of carbohydrate, a medium (182 g) about 25 g, and a large Honeycrisp (223 g) about 31 g. A cup of slices is roughly 15 g, which is an easy way to take a smaller carbohydrate portion.
| Portion | Weight | Net carbs |
|---|---|---|
| Small (149 g) | 149 g | 17 g |
| Medium (182 g) | 182 g | 20.7 g |
| Large (223 g) | 223 g | 25.4 g |
Logging an apple with Forkd tracks the carbs per meal from a photo, so hitting your target is something you can see rather than estimate.
Apple carbs: common questions
How many net carbs are in an apple?
A medium apple has about 25 g of total carbohydrate and 4 g of fiber, leaving roughly 21 g of net carbs.
Are apples good for a low-carb diet?
On a moderate low-carb diet, yes, in sensible portions. At about 21 g of net carbs a medium apple is too much for strict keto, but the fiber makes it a better carbohydrate than most processed snacks.
How many carbs are in an apple per 100g?
Apple with skin has about 13.8 g of carbohydrate per 100 g, including 2.4 g of fiber and 10.4 g of natural sugar.
Does apple juice have more carbs than an apple?
Per calorie it hits harder. Juice removes the fiber and concentrates the sugar, so it raises blood sugar much faster than a whole apple even at a similar carbohydrate count.
