A small box of raisins (about 43 g) provides roughly 130 calories and 2 g of fiber, per USDA FoodData Central. Drying removes water, so raisins are far more calorie-dense per bite than grapes. A small box is one serving — easy to overeat from a big bag. Use them as a natural sweetener in oatmeal or trail mix rather than eating by the handful.

Key facts:

  • Small box (43 g): ~130 kcal
