Fresh apricots may be small, but their calorie count varies depending on size and how you slice them. This apricot calories per slice calculator turns a whole fruit’s weight into a simple per-slice value, so you can log your snack, salad, or dessert without weighing every thin wedge.
All you need is the approximate weight of one apricot, how many fruits you are using, and how many slices you get from each fruit. The tool uses the standard USDA value of 48 calories per 100 g for raw apricots, but you can adjust that number if you are working with a different variety or a food label.
This is a practical companion for calorie tracking, meal prep, and portion control — whether you are counting macros, building a fruit tray, or just curious about what goes into your bowl.
🍑 Apricot & Slice Setup
Default is 48 kcal per 100 g for raw apricots. Adjust if using a different variety.
Step-by-Step Guide
- Choose a preset apricot size — small (30 g), medium (35 g), or large (45 g) — or type a custom weight in the weight field. If you have a kitchen scale, weighing the fruit is always the most accurate option.
- Enter the number of apricots you plan to slice. This lets the calculator add up calories for a whole batch, such as a fruit platter or a yogurt topping for the week.
- Enter how many slices you usually cut per apricot. The default is 6, which is about right for wedges on a cereal bowl; increase to 8–10 for thin salad slices.
- Leave the calorie value at 48 kcal per 100 g unless you have a specific reason to change it. Frozen or canned apricots can have slightly different labels, so use the number from the package when available.
- Press Calculate Calories. The result gives a per-slice value, per-apricot value, batch total, calories per gram, grams per slice, and a full breakdown of the math.
This workflow works equally well for a single afternoon snack and for meal prep portions.
How the Math Works
The calculator uses the energy density of raw apricots: about 48 kcal per 100 g. To find calories for any amount, convert the weight to a fraction of 100 g and multiply it by 48. If you enter your own calories per 100 g, the same formula applies:
Total weight = weight per apricot × number of apricots
Total calories = (total weight ÷ 100) × calories per 100 g
Calories per slice = total calories ÷ total slices
For example, one medium apricot at 35 g has (35 ÷ 100) × 48 = 16.8 kcal. If you slice it into 6 pieces, each slice is about 2.8 kcal. The math also tells you that a slice contains roughly 5.8 g of fruit, because grams are divided the same way: 35 g ÷ 6 = 5.8 g per slice.
Calories per gram matters for people who weigh portions rather than count slices. With raw apricot at 48 kcal per 100 g, that is 0.48 kcal per gram. Whether you track in grams, slices, or whole fruits, the energy is the same — the calculator simply expresses it in the unit you prefer.
Worked Examples
Example 1 — Small apricot, 6 slices: 30 g apricot, 1 fruit, 6 slices, 48 kcal/100 g. Total weight = 30 g. Total calories = 14.4 kcal. Calories per slice = 14.4 ÷ 6 = 2.4 kcal per slice.
Example 2 — Large apricot, 8 thin slices: 45 g apricot, 2 fruits, 8 slices each, 48 kcal/100 g. Total weight = 90 g. Total calories = (90 ÷ 100) × 48 = 43.2 kcal. Total slices = 16. Calories per slice = 43.2 ÷ 16 = 2.7 kcal per slice.
Notice that slicing the fruit more thinly does not change its calories — it just spreads the same energy across more slices. This is why per-slice numbers are only meaningful when you also know the slice count.
Standard Nutrition Reference
| Apricot size | Average weight | Calories per apricot | Calories per slice (6 slices) |
|---|---|---|---|
| Small | 30 g | 14.4 kcal | 2.4 kcal |
| Medium | 35 g | 16.8 kcal | 2.8 kcal |
| Large | 45 g | 21.6 kcal | 3.6 kcal |
| Per 100 g | 100 g | 48 kcal | — |
Weights are typical values for fresh raw apricots reported in USDA FoodData Central. Actual fruit size varies by variety and season, which is why the calculator lets you enter custom grams.
Tips for Accurate Tracking
- Weigh the apricot with the pit removed. The stone accounts for a meaningful portion of the whole fruit, and calorie databases report the edible flesh.
- Keep slice thickness fairly consistent. If you are mixing thick and thin pieces, the per-slice estimate becomes less reliable; weighing the batch and dividing by number of slices is more stable.
- Use the same slicing routine every time. If you normally slice an apricot into 5 chunks for yogurt, set slices per apricot to 5 rather than the default 6.
- Remember that dried apricots are a completely different food: dried fruit has about 241 kcal per 100 g because water is removed. Do not use this calorie value for dried slices.
- Pair this with the apricot net carbs calculator if you’re also tracking carbohydrate intake from the same fruit, and use the nutrition target calculator to see how apricot slices fit into your daily calorie goal.
Frequently Asked Questions
How many calories are in one slice of apricot?
For a typical medium apricot (35 g) cut into 6 slices, each slice contains about 2.8 kcal. Thin slices from a large apricot can be around 2.7 kcal; smaller apricots sliced into 6 give about 2.4 kcal per slice.
Does the number of slices change the calories?
No. Cutting a fruit into more pieces spreads the same total energy across more slices, so the per-slice number gets smaller. The total calories for the apricot remain unchanged. Always pair per-slice values with the slice count.
Can I use this for canned or frozen apricots?
Only if you adjust the calories per 100 g to match the product label. Canned apricots may be packed in syrup and can contain significantly more sugar and calories. Frozen unsweetened apricots are closer to raw, but check the package.
Is 48 kcal per 100 g always accurate?
It is the standard USDA value for raw apricots, but natural variation exists among varieties, ripeness, and growing conditions. For casual diet tracking the difference is tiny; for strict accuracy, weigh and check your specific food label or reference.
