Counting carrot slices? You're not alone. Raw carrots are a low-calorie snack, but the exact calories in a single slice vary with the carrot's size and how thickly you cut it. A medium raw carrot weighs about 61 grams and provides roughly 25 calories. Cut it into 15 even slices, and each slice comes to about 1.7 calories — enough to track when you're meal-prepping or logging a snack.
This calorie-per-slice calculator takes the guesswork out of portion math. Enter the weight of your carrot (or use the small/medium/large quick picks), tell the tool how many slices you cut, and it instantly returns total calories, calories per slice, grams per slice, and per-slice carbohydrates, fiber, sugar, and vitamin A. It's a handy companion for calorie tracking, diet planning, and healthy snack building.

How the Per-Slice Math Works
Raw carrots are about 88% water and 10% carbohydrate, with negligible fat and protein. The USDA FoodData Central lists raw carrot as roughly 41 kcal per 100 g. The calculator applies that calorie density to the carrot weight you enter:
Total carrot calories = (weight in grams ÷ 100) × 41
Calories per slice = total carrot calories ÷ number of slices
Grams per slice = weight in grams ÷ number of slices
For example, a 75 g carrot contains (75 ÷ 100) × 41 = 31 kcal. If you slice it into 15 pieces, each slice is 31 ÷ 15 ≈ 2.1 kcal. The same math powers the carb, fiber, and sugar estimates, using these per-100 g values for raw carrots: 9.6 g carbs, 2.8 g fiber, 4.7 g natural sugars, and about 835 µg RAE vitamin A (~93% of the Daily Value). All totals scale linearly with weight, so the formula remains accurate whether you use a baby carrot or a jumbo one.
Worked Examples
Example 1: Thin slices from a medium carrot. A 75 g carrot cut into 30 thin rounds. Total calories = 31 kcal. Per slice = 31 ÷ 30 ≈ 1.03 kcal, and each slice weighs about 2.5 g. A 10-slice snack would be about 10 kcal.
Example 2: Thick chunks for roasting. Take a 100 g carrot and cut it into 8 chunky coins. Total calories = 41 kcal. Per chunk = 41 ÷ 8 ≈ 5.1 kcal. A side of three thick slices is about 15 kcal before oil.
Example 3: Half a carrot. Suppose you weigh a half-carrot portion at 35 g and cut it into 12 small slices. Total = (35 ÷ 100) × 41 ≈ 14.4 kcal; per slice = 14.4 ÷ 12 ≈ 1.2 kcal. Weighing raw portions before slicing gives the most reliable result.
Reference Nutrition Table
Typical values per 100 g of raw carrot, based on USDA FoodData Central, are shown below. Use them as a benchmark when comparing your own slice sizes.
| Nutrient | Amount per 100 g | Approx. per 15 g (5–6 medium slices) |
|---|---|---|
| Calories | 41 kcal | 6.2 kcal |
| Carbohydrate | 9.6 g | 1.4 g |
| Fiber | 2.8 g | 0.4 g |
| Natural sugars | 4.7 g | 0.7 g |
| Protein | 0.9 g | 0.1 g |
| Fat | 0.2 g | 0.03 g |
| Vitamin A (RAE) | 835 µg (93% DV) | 125 µg (14% DV) |
DV = Daily Value based on a 2,000-calorie diet. Actual values vary slightly by carrot variety, growing conditions, and freshness.
Factors That Affect Accuracy
Calorie-per-slice estimates are as good as the assumptions behind them. Carrot size is the biggest variable: a 'medium' carrot can weigh anywhere from 50 to 75 g, and a 'large' one can exceed 100 g. If you rely only on visual size categories, your total can be off by 30% or more. Weighing the carrot on a kitchen scale removes most of the uncertainty.
Slice thickness changes how many slices a carrot produces and therefore changes per-slice calories. A 3 mm thin slice of a medium carrot weighs roughly 2–3 g, while a 12 mm thick coin can weigh 6–10 g. Peeled carrots lose a little fiber and volume, but the calorie difference is minor. Cooking carrots also removes some water and concentrates sugars slightly — roasted carrot chunks have a higher calorie density per gram than raw ones. For raw snacking, the numbers here are accurate; for cooked dishes, consider the added oil or butter, which contributes far more calories than the carrot itself.
Frequently Asked Questions
How many calories are in one baby carrot?
Baby-cut carrots are stamped from larger carrots and weigh about 10–15 g each. At 41 kcal per 100 g, one 12 g baby carrot has roughly 5 calories. The per-slice calculator works for any carrot shape if you use the actual weight.
Does peeling change the calories?
Not meaningfully. The skin contains a tiny amount of extra fiber and nutrients, but for calorie counting the difference is under 1 kcal per carrot.
Are cooked carrots higher in calories?
Per 100 g, cooked carrots (boiled) are similar to raw — around 35 kcal/100 g because water dilutes them. Roasted carrots can be slightly more concentrated, around 50–55 kcal/100 g. The bigger concern is added fat: a tablespoon of olive oil adds about 119 kcal, which dwarfs the carrot's own calories.
Can I use this for sliced carrot sticks or matchsticks?
Yes. Enter the total weight of the cut carrot and the number of sticks or strips. The tool divides the calories evenly, which is exactly what you want for portion tracking.

Tips for Tracking Carrot Slices
- Weigh before slicing. Raw weight is the most consistent baseline and matches USDA nutrition data.
- Use the same cutting rhythm. If you always cut at about the same thickness, your slices will be close enough for logging.
- Count slices in multiples. A 75 g carrot yields roughly 15 medium slices, so if you eat 5 slices that's about one-third of the carrot — approximately 10 calories.
- Don't forget dips. Hummus, ranch, and peanut sauce add most of the calories in a veggie snack. A 2-tablespoon hummus serving is about 80 kcal.
- Log cooked carrot dishes by weight too. If you're adding carrots to soup or stir-fry, weigh the raw pieces before they go in and use the raw density.
- Compare fruits and vegetables fairly. For another quick snack comparison, try the strawberry calorie calculator to see how a sweet fruit alternative stacks up.
