Lychee Calories Per Serving Calculator

Fresh lychees are a sweet tropical treat that are dangerously easy to eat by the handful. This serving-size calorie calculator turns your lychee portion into calories and macronutrients, whether you count individual fruits, weigh them in grams or ounces, or measure a cup. It uses standard nutrition data for raw lychee so you can estimate total calories, carbohydrates, protein, fat, sugar, and fiber in seconds.

Choose your amount, pick the unit that matches how you eat lychees — individual lychees, grams, ounces, or cups — and press Calculate. The result panel shows the nutrition breakdown plus a simple step-by-step explanation so you can see how each number is derived. You can also use the quick-fill buttons for common serving sizes like 1 lychee or 100 g.

This calculator is ideal for calorie counters, macro trackers, and fruit lovers who want a reliable portion-based estimate without pulling up a nutrition database every time.

How to Use This Tool

Start by entering an amount in the input field. The default unit is individual lychees, which is the easiest choice when you are eating from a bowl. If you have a kitchen scale, switch to grams or ounces for a more accurate measurement. For recipes, cups are convenient, but be consistent — the calculator assumes a cup holds about 190 g of peeled lychee flesh, which can vary depending on how tightly the fruit is packed.

The tool assumes one average lychee weighs about 10 g after removing the skin and seed. If your fruit is significantly larger or smaller, weigh a few lychees and use the gram unit instead for a better estimate. The nutrition data is based on raw lychee from the USDA FoodData Central database: roughly 66 calories, 16.5 g carbohydrates, 15.2 g sugar, 1.3 g fiber, 0.83 g protein and 0.44 g fat per 100 g of edible flesh.

Quick tip: The preset buttons set the amount and unit in one click. After choosing a preset, press Calculate to refresh the results. This works well for comparing a single lychee, a small handful, and a full 100 g serving.

Formula Explained

The calculator performs a two-step conversion. First, it converts your chosen serving size into grams of edible lychee flesh:

Grams = Number of lychees × 10
Grams = Ounces × 28.3495
Grams = Cups × 190

Then it applies the per-100g nutrient values:

Nutrient value = (Grams ÷ 100) × value per 100 g

For example, to find the calories in 150 g of lychees: (150 ÷ 100) × 66 = 99 kcal. The same calculation works for carbohydrates, protein, fat, sugar, and fiber.

Example: If you enter 5 lychees, the calculator converts 5 × 10 = 50 g. Calories = (50 ÷ 100) × 66 = 33 kcal. Carbs = (50 ÷ 100) × 16.5 = 8.25 g.

If you track portions by ounce, the conversion to grams happens before any nutrient math, so the result is always based on weight. The step-by-step breakdown shown below the results helps you follow along.

Worked Examples

Example 1 — A snack of 12 lychees:
Weight: 12 × 10 = 120 g
Calories: (120 ÷ 100) × 66 = 79 kcal
Carbohydrates: (120 ÷ 100) × 16.5 = 19.8 g
Sugar: 18.2 g; Protein: 1.0 g; Fat: 0.5 g

Example 2 — 150 g on a food scale:
Calories: (150 ÷ 100) × 66 = 99 kcal
Carbs: (150 ÷ 100) × 16.5 = 24.8 g
Protein: 1.2 g; Fat: 0.7 g

Example 3 — 1 cup (190 g) in a fruit salad:
Calories: (190 ÷ 100) × 66 = 125 kcal
Carbs: 31.4 g; Sugar: 28.9 g; Fiber: 2.5 g

As these examples show, lychees are mostly carbohydrate and water, so their calorie density is fairly low. But the sugar content adds up quickly when portions grow.

Tips for Accurate Tracking

Weigh without skin and seed. Lychee shells and seeds are inedible, so weigh only the peeled flesh. A whole lychee with peel and seed can weigh 20 g or more, which would roughly double the calorie estimate.

Check the variation. Lychee fruit size varies by variety and growing season. Some average 8 g, while large varieties reach 12 g. If accuracy matters, weigh 5 fruits and divide by 5 to find your personal average.

Avoid canned lychee confusion. Lychees canned in syrup contain significantly more sugar and calories than fresh fruit. This calculator is only for fresh, raw lychees. Check the label if you are using canned or dried lychee.

Frequently Asked Questions

How many calories are in one lychee? A typical 10 g lychee has about 6.6 calories. If your lychees are larger, use the gram or ounce unit for a more precise number.

Are lychees high in sugar? Yes, lychees contain about 15 g of sugar per 100 g. The sugar content is high relative to other fruits, but the portion size is usually small. A 10-fruit serving provides roughly 15 g of sugar.

Can I use this calculator for frozen lychees? Frozen lychees without added sugar are nutritionally similar to fresh. If the package lists any added syrup or sugar, use the label values instead.

How does this compare with other fruits? Lychees are more sugar-dense than berries or melons but similar to grapes. If you are comparing fruit options, the fruit carbs per 100g calculator may help.

For ounce-based serving sizes, the lychee calories per ounce calculator lets you check small portions quickly.
