Fresh raspberries are one of the lower-carb berries, but the net carb count is not the same as the total carb number on a label. Because raspberries are packed with fiber, a serving can look higher in carbs than it really is from a digestible-energy standpoint. This calculator turns your serving size — grams, ounces, US cups, or individual berries — into estimated net carbs using standard USDA nutrition values.
Net carbs are calculated as total carbohydrates minus dietary fiber and sugar alcohols. The tool uses 11.94 g of total carbs and 6.5 g of fiber per 100 g of raw raspberries by default, and you can open the custom values section to match a specific package or recipe. Ideal for keto tracking, low-carb meal planning, and anyone who wants a clearer picture of how many digestible carbs a bowl of berries actually contains.

Estimate the digestible, net carbohydrate content of fresh raspberries for your exact serving size.
How Net Carbs Are Calculated
Net carbs are the grams of carbohydrate your body actually digests into glucose. Dietary fiber is largely resistant to digestion, and sugar alcohols are only partially absorbed, so both are commonly subtracted when estimating digestible carbohydrates. The general formula is:
For fresh raspberries, the calculator starts with USDA FoodData Central averages: 11.94 g total carbs, 6.5 g fiber, and 0 g sugar alcohols per 100 g. That gives roughly 5.44 g net carbs per 100 g of raw fruit. When you choose a different serving, the calculator multiplies these per-100 g figures by the equivalent weight of your serving.
Worked Examples
These examples assume whole, raw raspberries with no added sugar, and values are rounded to one decimal place.
Raspberry Nutrition Reference
| Serving | Weight | Total carbs | Fiber | Net carbs |
|---|---|---|---|---|
| 100 g | 100 g | 11.94 g | 6.5 g | 5.44 g |
| 1 US cup | 123 g | 14.69 g | 8.0 g | 6.69 g |
| 1 oz | 28.35 g | 3.38 g | 1.84 g | 1.54 g |
| 10 berries ≈ 20 g | 20 g | 2.39 g | 1.30 g | 1.09 g |

Limitations & Accuracy Notes
Net carbs is a practical concept rather than a precise lab measurement. The FDA does not define net carbs on Nutrition Facts labels, so different apps and diet plans handle fiber and sugar alcohols differently. Some subtract all fiber; others only subtract fiber when it is above a threshold; a few subtract half the sugar alcohols. Because raspberries contain no meaningful sugar alcohols, the main variable is simply how much fiber you choose to subtract.
Serving size also matters. Cups are convenient but less precise than grams, since berries settle and vary in size. If you are tracking strict macros, weighing raspberries on a kitchen scale is the most accurate approach. Frozen unsweetened raspberries generally have similar carbohydrates to fresh, but sweetened or juice-packed raspberry products will be much higher in sugar and net carbs.
Frequently Asked Questions
How many net carbs are in a cup of raspberries?
Using the USDA defaults, one US cup of raw raspberries (123 g) contains about 6.7 g net carbs: 14.7 g total carbs minus 8.0 g fiber. This makes raspberries one of the most keto-friendly common berries in reasonable portions.
Can I eat raspberries on a keto diet?
Yes. A modest serving of roughly half to one cup fits easily into a standard 20 g daily net-carb budget, especially if you pair them with plain yogurt, cottage cheese, or nuts. Just measure carefully if you are new to tracking.
Do frozen raspberries have the same net carbs?
Unsweetened frozen raspberries are very close to fresh in carbohydrate content because freezing does not add or remove carbs. Check the label for added sugar or syrup, which can raise net carbs considerably. Dried raspberries, by contrast, are concentrated and much higher in net carbs per gram.
