Peanuts are a popular snack and ingredient, but their carbohydrate content can vary depending on preparation and serving size. This calculator helps you determine the net carbs, total carbs, and fiber in peanuts per 100 grams, making it easier to track your macronutrients for keto, low-carb, or general healthy eating plans.
Whether you’re meal prepping, counting macros, or just curious about the nutritional profile of raw, roasted, or boiled peanuts, this tool provides instant, accurate results. Simply select the type of peanut and enter the weight to see a full breakdown of carbs, fiber, and net carbs.
🥜 Peanut Carbs Per 100g Calculator
How to Use This Tool
Using the Peanut Carbs Per 100g Calculator is straightforward. Start by selecting the type of peanut you have — raw, dry roasted, boiled, or oil roasted — from the dropdown menu. Then enter the weight in grams (the default is 100 g, but you can adjust it to match your portion). Optionally, choose whether to include fiber in the displayed results. Click "Calculate" to see the total carbs, fiber, and net carbs for your specific serving. Use the "Reset" button to clear the results and start over.
Formula Explained
The calculation is based on standard USDA nutritional data per 100 grams of peanuts. The tool multiplies the per-100g values by your entered weight divided by 100. Net carbs are calculated as total carbohydrates minus dietary fiber. The formulas are:
- Total Carbs (adjusted) = (Total Carbs per 100g) × (Weight / 100)
- Fiber (adjusted) = (Fiber per 100g) × (Weight / 100)
- Net Carbs = Total Carbs (adjusted) − Fiber (adjusted)
These values are based on data from the USDA FoodData Central database, which provides reliable macronutrient profiles for a wide range of foods.
Worked Examples
Factors Affecting Accuracy
The accuracy of this calculator depends on the precision of the input weight and the consistency of the peanut type. Different brands or preparation methods (e.g., added oils, salt, or flavorings) can slightly alter the carbohydrate content. The values used are averages from the USDA and may not reflect every product on the market. For the most accurate tracking, always check the nutrition label on your specific peanut product.
Frequently Asked Questions
Are peanuts keto-friendly? Yes, peanuts are relatively low in net carbs (about 7-8 g per 100 g for raw peanuts) and can fit into a keto diet in moderation. However, they are calorie-dense, so portion control is important.
Why do boiled peanuts have higher carbs than raw? Boiling peanuts can concentrate the carbohydrates because water is absorbed and the weight changes, but the carb content per 100 g is similar to roasted varieties. The USDA data shows boiled peanuts have 21.3 g total carbs per 100 g, which is higher than raw due to the cooking process.
Can I use this calculator for peanut butter? This tool is designed for whole peanuts. Peanut butter has a different nutritional profile (often with added fats and sugars). For peanut butter, use a dedicated calculator or check the label.
What is net carbs and why does it matter? Net carbs are the carbohydrates that your body can digest and use for energy. Fiber is not digested, so it is subtracted from total carbs. Many low-carb and keto diets track net carbs to manage blood sugar and ketosis.
Real-World Applications
