Raspberries are a favorite for low-carb and keto dieters, but their carbohydrate content can vary depending on whether you measure fresh, frozen, or pureed berries. This calculator helps you determine the exact carbohydrate content per 100 grams of raspberries, including total carbs, net carbs, and fiber. Whether you're tracking macros, managing blood sugar, or simply curious about the nutritional profile, this tool gives you quick, accurate numbers.
Simply enter the weight of your raspberries (in grams or ounces) and choose the form (fresh, frozen, or pureed). The calculator will instantly show you the total carbohydrates, dietary fiber, and net carbs per 100g, along with a breakdown for your specific portion. Perfect for meal planning, recipe scaling, and nutrition logging.

How to Use This Tool
Using the Raspberry Carbs Per 100g Calculator is straightforward. Enter the weight of your raspberries in grams or ounces, select the form (fresh, frozen, or pureed), and click "Calculate." The tool instantly displays the carbohydrate content per 100 grams, along with the fiber and net carbs. It also calculates the total carbs and net carbs for your specific portion, making it easy to log your intake accurately.
For quick reference, use the preset buttons to fill in common amounts like 100 g, 150 g, or 1 oz. If you're using a recipe that calls for a cup of raspberries, the "1 cup" preset automatically enters 123 grams, which is the average weight of a cup of fresh raspberries. This saves time and ensures consistency.
How It Works
The calculator uses standard nutritional data for raspberries. For fresh raspberries, the USDA FoodData Central lists approximately 11.94 grams of total carbohydrates and 6.5 grams of dietary fiber per 100 grams. Frozen raspberries have slightly higher values—about 12.04 grams of carbs and 6.6 grams of fiber—because freezing can concentrate the fruit's solids. Pureed raspberries, which are often used in sauces and smoothies, have a slightly lower fiber content due to processing, averaging around 11 grams of carbs and 5 grams of fiber per 100 grams.
Net carbs are calculated by subtracting fiber from total carbohydrates, since fiber is not digested and does not raise blood sugar. This is a key metric for low-carb and ketogenic diets. The formula is simple: Net Carbs = Total Carbs − Fiber. For your portion, the calculator multiplies the per-100g values by your weight and divides by 100.
Worked Examples
Example 1: You eat 150 grams of fresh raspberries. Total carbs = 11.94 × 150 / 100 = 17.91 g. Fiber = 6.5 × 150 / 100 = 9.75 g. Net carbs = 17.91 − 9.75 = 8.16 g.
Example 2: You use 1 cup (123 g) of frozen raspberries in a smoothie. Total carbs = 12.04 × 123 / 100 = 14.81 g. Fiber = 6.6 × 123 / 100 = 8.12 g. Net carbs = 14.81 − 8.12 = 6.69 g.
Tips & Best Practices
- Always weigh your raspberries for the most accurate carb count, especially if you're tracking macros strictly.
- If you're using a food scale, remember that 1 cup of fresh raspberries typically weighs about 123 grams, but this can vary slightly based on berry size and packing.
- For frozen raspberries, measure them while still frozen to avoid water weight from thawing.
- When logging in an app, check whether the entry is for fresh or frozen—values differ slightly.
Factors Affecting Accuracy
The nutritional values used are averages from the USDA. Actual carb content can vary by variety, ripeness, and growing conditions. For example, some raspberry varieties may have slightly higher sugar content. Additionally, if you add sweeteners or other ingredients, those will add carbs. The calculator assumes plain raspberries with no added sugar.
Frequently Asked Questions
Are raspberries keto-friendly?
Yes, raspberries are one of the lower-carb fruits. With about 5.4 grams of net carbs per 100 grams, they can fit into a ketogenic diet in moderation. A typical serving of 100 grams provides only about 5.4 grams of net carbs.
What is the difference between total carbs and net carbs?
Total carbs include all carbohydrates, including fiber. Net carbs subtract fiber because fiber is not digested and doesn't raise blood sugar. For low-carb diets, net carbs are often the more relevant number.
Can I use this calculator for other berries?
No, this calculator is specifically for raspberries. Other berries like blueberries or strawberries have different carb profiles. You can use our blueberry calorie calculator for blueberries, or check our fruit fiber calculator for a broader comparison.
