Cashews are a satisfying, nutrient-dense nut, but they contain more carbohydrates than many other varieties. This cashew net carbs calculator shows exactly how many digestible carbs are in any serving, whether you measure in grams, ounces, cups, or tablespoons.
Net carbs are calculated by subtracting dietary fiber from total carbohydrates, and any sugar alcohols you enter are subtracted too. Since fiber is not fully digested, it does not raise blood sugar the way other carbs do. This makes the result useful for keto, low-carb, and diabetic meal planning.
The tool uses standard USDA values for raw cashew kernels, so you get consistent, reliable numbers every time. It also shows a step-by-step breakdown so you can see exactly how the math works.

How the Net Carb Count Is Calculated
Net carbs are not a standard nutrient value found on food labels. Instead, they are an estimate of the carbohydrates your body actually absorbs and converts into glucose. The general formula is:
Fiber is subtracted because humans lack the enzymes needed to digest most forms of dietary fiber, so it passes through the gastrointestinal tract largely intact and does not raise blood sugar the way digestible carbs do. Sugar alcohols are partially absorbed, but many varieties have a minimal effect on blood sugar; subtracting the full gram weight is the common strict-keto approach, though some people subtract only half for sugar alcohols like maltitol. This calculator uses the USDA FoodData Central values for raw cashew kernels, which is the same standard reference most nutrition tracking apps rely on.
Step-by-Step Guide
- Enter the serving amount in the number box.
- Choose the matching unit: grams, ounces, cups, or tablespoons.
- Optionally enter the grams of sugar alcohols if your specific cashew product lists them. Plain raw or dry-roasted cashews usually contain none.
- Click Calculate Net Carbs to see total carbs, fiber, sugar alcohols, sugars, and the final net carb count.
- Use the quick-fill pills for common serving sizes like 1 oz (28 g), ¼ cup (30 g), or 100 g.
The calculator handles all unit conversions for you. One ounce equals 28.3495 grams, one cup of cashew kernels weighs about 130 grams, and one tablespoon weighs about 8.125 grams. These weights assume whole, raw cashew pieces, so finely ground cashew flour or meal will have a slightly different density and weight per cup.
Reference: Cashew Nutrition per 100 g
The values below are based on raw cashew nuts as listed in the USDA FoodData Central database.
| Nutrient | Amount |
|---|---|
| Total carbohydrate | 30.19 g |
| Dietary fiber | 3.3 g |
| Total sugars | 5.91 g |
| Net carbs (calculated) | 26.89 g |
| Fat | 43.85 g |
| Protein | 18.22 g |
| Calories | 553 kcal |
For comparison, most other tree nuts are lower in carbs: almonds contain about 21.6 g total carbs and 12.5 g fiber per 100 g (roughly 9 g net), pecans contain about 13.9 g total carbs and 9.6 g fiber, and walnuts about 13.7 g total carbs and 6.7 g fiber. Cashews sit at the higher end of the nut spectrum, which is why portion size matters more for them when you are tracking carbs.
Worked Examples
Question: How many net carbs are in a ¼-cup serving of raw cashews?
Answer: A ¼-cup serving weighs about 30 g. Total carbs = 30 × 30.19 / 100 = 9.06 g. Fiber = 30 × 3.3 / 100 = 0.99 g. Net carbs = 9.06 − 0.99 = 8.07 g. If your cashew product lists sugar alcohols, subtract those as well.
Question: How many net carbs are in a 1 oz (28 g) handful?
Answer: Total carbs = 28 × 30.19 / 100 = 8.45 g. Fiber = 28 × 3.3 / 100 = 0.92 g. Net carbs = 8.45 − 0.92 = 7.53 g. Since 1 oz is smaller than ¼ cup, the net carb difference is noticeable, which is why weighing your food gives the most accurate number.
Tips for Low-Carb and Keto Meal Planning
- Raw and dry-roasted plain cashews have similar carb counts; avoid honey-roasted, chocolate-covered, or yogurt-coated varieties, which add significant sugar.
- Portion control matters. A standard serving is about 18–20 whole cashew kernels, and it is easy to eat twice that in one sitting, which doubles the net carb load.
- Pair cashews with a protein or fat source like cheese, yogurt, or a few almonds to help balance the blood sugar response and increase satiety.
- Compare nutrition labels when shopping, because oils, coatings, spice blends, and added sweeteners all change the net carb total.
- Store cashews in an airtight container in a cool spot; rancid nuts taste bitter, and that bitterness often leads people to reach for higher-carb snacks instead.
Frequently Asked Questions
Yes, in moderation. A standard 28 g serving contains about 7.5 g net carbs, which fits into many low-carb and keto daily carbohydrate budgets. Larger handfuls add up quickly, so weighing is recommended. If you are tracking a strict 20 g net carb limit, budget a single serving for the day.
Carbohydrate counts can vary slightly because of crop differences, processing methods, and the rounding rules used on food labels. The USDA database provides a standardized reference, but the label on your specific package is generally the most accurate for that product. This calculator lets you adjust the sugar alcohol entry manually so it can match any label.
It depends on the type. Erythritol and monk fruit sweeteners have negligible digestible carbs and can be subtracted fully. Maltitol and sorbitol have a higher glycemic impact, so some people subtract only half of the labeled grams. When in doubt, check the sweetener type on the ingredient list and consult your healthcare provider or dietitian if you eat sweetened nuts regularly.
Dry-roasted, salted cashews have nearly identical carbohydrate values to raw kernels because roasting mainly affects moisture and fat content. Oil-roasted cashews may add a small amount of fat and calories but very little carbohydrate. Flavored varieties, however, can add 2–10 g of sugar per serving depending on the coating.
