A typical serving of raisins (1 small box, 43 g) has about 129 calories. Per 100 g: 299 kcal, 3.3 g protein, 79.3 g carbs, 0.3 g fat. The same 100 g carries 4.5 g of fiber and 65.2 g of sugar. Most of the energy comes from carbohydrate.

Drying the grape concentrates everything; a small box equals a whole bunch. On the energy-density scale, 299 kcal per 100 g puts raisins at the high end. Fiber is the standout at 4.5 g per 100 g, which slows a portion down more than the calorie count suggests.

A typical serving (1 small box, 43 g) has about 129 calories, and 100 g has 299 kcal. Calories scale with weight, so double the portion means double the number.
There are 3.3 g of protein in 100 g of raisins, which works out to about 1.4 g per serving (1 small box). Treat it as an energy source rather than a protein source.
Sugar comes to 65.2 g per 100 g, so 1 small box (43 g) delivers roughly 28 g. That sugar is already counted inside the calorie figures on this page.
Every value on this page comes from USDA FoodData Central, entry 168165 (SR Legacy). Serving figures are converted from the per-100-g data, so rounding can shift a total by a calorie or two.
