Quick Answer: Calories in One Apple
A medium apple (about 182 grams) contains approximately 95 calories.
But apples come in many sizes and types, which means calorie counts can vary more than most people realize.
Calories in Apples by Size & Weight
| Apple Size | Weight (Approx.) | Calories |
|---|---|---|
| Small | 149 g | ~77 calories |
| Medium | 182 g | ~95 calories |
| Large | 223 g | ~116 calories |
| Per 100 g | — | ~52 calories |
Why this matters: Most people underestimate apple size. A large apple can contain nearly 40 more calories than a small one.
Calories in Apples by Variety
Different apple varieties vary slightly in calories due to sugar content and density.
| Apple Variety | Calories (per medium apple) |

| Granny Smith | ~80–85 |
| Gala | ~90–95 |
| Red Delicious | ~95 |
| Fuji | ~100–105 |

Key insight: Sweeter apples tend to have slightly more calories, but the difference is modest.
Calories in Apples by Form & Preparation
Preparation dramatically changes calorie density.
| Apple Form | Serving Size | Calories |
|---|---|---|
| Raw apple | 1 medium | ~95 |
| Apple slices | 1 cup | ~65 |
