Pears are one of the most popular fall and winter fruits, but they are not a no-carb food. A medium raw pear with skin contains about 27 grams of carbohydrate, roughly 5.5 grams of fiber, and 17 grams of naturally occurring sugar. If you track macros, follow a low-carb meal plan, or manage diabetes, knowing exactly how many carbs are in your pear serving makes planning easier.
This Pear Carbs Calculator turns a simple weight or fruit size into a full carb and calorie breakdown in seconds. Choose a small, medium, or large pear, or enter a custom weight in grams, then set the number of pears or servings. The tool instantly calculates total carbohydrates, net carbs, fiber, sugar, and calories using standard USDA nutrition reference values.
The optional net carbs view subtracts fiber from total carbs, which is a popular approach in low-carb and keto diet planning. Whether you are logging food in an app, adjusting insulin ratios, or building a balanced snack plate, this calculator gives you the numbers you need quickly and consistently.
🍐 Pear Carbs Calculator
Estimate total carbs, net carbs, fiber, sugar, and calories in pears based on weight.
How to Use This Tool
Start by choosing a pear size that matches what you are eating. The small, medium, and large presets use typical raw pear weights with skin: about 148 g, 178 g, and 222 g. If you have a food scale, pick Custom weight and enter the exact grams of the edible portion. Then type the number of pears or servings you plan to eat. For example, enter 0.5 for half a pear or 2 for two medium pears.
The calculator applies USDA standard reference values for raw pears: approximately 15.2 g of carbohydrate, 3.1 g of fiber, 9.8 g of sugar, and 57 kcal per 100 g. After you click Calculate Carbs, the result card shows total carbs, net carbs, fiber, sugars, and calories for your exact serving. If you prefer net carbs, leave the checkbox enabled; otherwise, uncheck it to see total carbohydrates as the headline number.
How Carb Counts Are Calculated
All estimates are built from USDA FoodData Central values for raw pears. The formula is straightforward:
Total carbs = (weight in grams ÷ 100) × 15.23 g
Fiber = (weight in grams ÷ 100) × 3.1 g
Net carbs = total carbs − fiber
Sugars = (weight in grams ÷ 100) × 9.75 g
Calories = (weight in grams ÷ 100) × 57 kcal
Net carbs are commonly used in low-carb and keto meal planning because fiber is not fully digested and does not raise blood glucose the way most other carbohydrates do. The USDA data are averages, so a particular pear can differ slightly depending on variety, ripeness, and water content. The tool rounds displayed values to the nearest tenth of a gram for readability.
Worked Examples
Example 1 — one small pear: A small pear weighs about 148 g. Total carbs = 1.48 × 15.23 = 22.5 g. Fiber = 1.48 × 3.1 = 4.6 g. Net carbs = 22.5 − 4.6 = 17.9 g. Sugars = 1.48 × 9.75 = 14.4 g. Calories = 1.48 × 57 = 84 kcal.
Example 2 — two medium pears: Two medium pears weigh about 356 g. Total carbs = 3.56 × 15.23 = 54.2 g. Fiber = 3.56 × 3.1 = 11.0 g. Net carbs = 54.2 − 11.0 = 43.2 g. Calories = 3.56 × 57 = 203 kcal.
Example 3 — 100 g of pear: This is a typical snack-size reference portion. Total carbs = 15.2 g, net carbs = 12.1 g, sugar = 9.8 g, fiber = 3.1 g, and calories = 57 kcal.
Pear Nutrition Reference Table
The table below shows approximate values for common pear portions using USDA data. Use these as a quick reference when a scale is not available.
| Serving | Weight (g) | Total Carbs (g) | Fiber (g) | Net Carbs (g) | Sugars (g) | Calories |
|---|---|---|---|---|---|---|
| 100 g (about ½ medium pear) | 100 | 15.2 | 3.1 | 12.1 | 9.8 | 57 |
| Small pear | 148 | 22.5 | 4.6 | 17.9 | 14.4 | 84 |
| Medium pear | 178 | 27.1 | 5.5 | 21.6 | 17.4 | 102 |
| Large pear | 222 | 33.8 | 6.9 | 26.9 | 21.7 | 127 |
| 1 cup sliced pear | 140 | 21.3 | 4.3 | 17.0 | 13.7 | 80 |
Serving weights are approximations. If a pear looks unusually large or small, use the custom weight option for a more precise estimate.
Tips for Tracking Pear Carbs Wisely
- Weigh before you peel. The nutrition facts in this calculator refer to pears eaten with the skin. If you peel the pear, total carbs stay similar, but fiber may drop slightly. Remove the core before weighing the edible flesh.
- Decide on net vs total carbs first. If you follow a keto or very low-carb diet, net carbs are often the number you track. If you manage diabetes with insulin or carb counting, many dietitians recommend using total carbohydrates unless your care team tells you otherwise.
- Be careful with dried pears. Drying removes water and concentrates sugars, so a small handful of dried pear can contain far more carbohydrate than the same weight of fresh pear. Do not use this calculator for dried pear products.
- Pair pears with protein or fat. Adding a few almonds, a spoon of peanut butter, or a piece of cheese can slow digestion and make a pear snack more balanced. You can estimate the extra carbs with other food calculators on this site, such as the Whole Carbs Calculator.
Frequently Asked Questions
Are most pear carbs from sugar? Yes. A medium pear has about 17.4 g of naturally occurring sugar and roughly 4.6 g of other carbohydrate from starch and organic acids. Pear sugar is mostly fructose and glucose, but it still counts toward your daily carbohydrate total.
Why does my nutrition app show different numbers? Apps use different database entries and serving sizes. Some list pears with skin, some without, and some use larger or smaller serving weights. The values here are based on USDA standard reference data, which is a reliable baseline.
Should I subtract fiber for diabetes management? Not automatically. Some people use net carbs, but medical nutrition therapy for diabetes usually emphasizes total carbohydrates for mealtime insulin and blood sugar management. Always follow the guidance of your healthcare provider. To help connect pear sugars with daily added sugar goals, try the Added Sugar Limit Calculator.
