A small apple has about 15–20 grams of carbs , depending on its exact size and variety.

Quick Scoop

For a typical small raw apple with skin (about 2.5" diameter, roughly 4 per pound):

  • Total carbs: around 15 g per small apple.
  • Some nutrition databases list up to ~20 g carbs for a “small apple” depending on weight (often closer to 120 g instead of 100 g).
  • Net carbs (carbs minus fiber) generally land around 12–17 g for a small apple.

So if you just need a practical answer for tracking:

Count ~15–20 g carbs for one small apple with the skin on.

If you’re on a strict low-carb or keto plan aiming for under ~30 g per day, a small apple can fit, but it will use up a big chunk of your daily carb budget.
