Cashews are a rich source of heart-healthy monounsaturated fats, but they also pack a surprising number of calories per handful. If you are tracking fat grams for a ketogenic, low-carb, or calorie-controlled eating plan, knowing exactly how much fat is in your serving makes portioning much easier. This cashew fat calculator converts any amount — grams, ounces, cups, or individual cashews — into total fat, saturated fat, and calories from fat.
Raw, dry-roasted, and oil-roasted cashews differ noticeably in fat content, so the calculator uses separate nutrition profiles for each form. Simply choose your cashew type, enter your portion, and the tool gives an instant breakdown, including the share of your daily fat allowance. Designed for home cooks, meal-preppers, and macro trackers, this is a fast, practical way to keep portions honest.
Note: the numbers come from standard USDA reference data and are rounded estimates; actual values can vary by brand and seasoning.

How to Use This Calculator
Enter the amount of cashews you plan to eat in the first field. The calculator accepts four units: grams, ounces, cups, or whole cashews. If you are measuring with a kitchen scale, choose grams for the most precise result; if you are following a recipe that lists “1 cup” or “2 oz,” use those options instead. One whole cashew in the calculator is treated as 1.5 g, which is a reasonable average for standard kernel sizes.
After selecting the amount, choose the form of cashews: raw, dry roasted, or oil roasted. This matters because dry-roasted and especially oil-roasted cashews absorb or retain extra fat during processing. Press Calculate fat and the results panel updates with total fat, saturated fat, calories from fat, and the percentage of the Daily Value for fat. The step-by-step breakdown shows exactly how the number was derived, so you can verify the math or adjust your portion.
Use the quick-serving buttons for common portions: a 1 oz serving, a casual 30 g handful, a half cup, or a 100 g reference portion. These buttons fill in the amount field for you and set the unit to grams; you still choose your cashew form before calculating.
Fat Values Behind the Calculator
The calculator uses standard USDA nutrient data per 100 grams of cashews. For raw cashews, total fat is approximately 43.85 g; for dry roasted, 46.35 g; and for oil roasted, 47.78 g. The saturated fat values are roughly 7.78 g, 8.01 g, and 8.29 g, respectively. The calorie content per 100 g is also included so the calories-from-fat line can be compared with the total energy you would get from the portion.
Calories from fat = total fat (g) × 9
Fat Daily Value = total fat (g) ÷ 78 g × 100
If you are counting calories, note that fat provides 9 kcal per gram, while carbohydrate and protein provide only 4 kcal per gram. A typical 30 g handful of raw cashews contains about 13.2 g of fat, which is roughly 119 kcal from fat — much higher than the same weight of most fruit or cooked grains.
Worked Examples
Example 1: 1 oz (28 g) dry-roasted cashews
Weight: 28.0 g
Fat value: 46.35 g per 100 g
Total fat = 28.0 × 46.35 ÷ 100 = 13.0 g
Saturated fat = 28.0 × 8.01 ÷ 100 = 2.2 g
Calories from fat = 13.0 × 9 = 117 kcal
Fat Daily Value = 13.0 ÷ 78 × 100 = 16.7%
Example 2: 30 g raw cashews (about ¼ cup)
Weight: 30.0 g
Fat value: 43.85 g per 100 g
Total fat = 30.0 × 43.85 ÷ 100 = 13.2 g
Saturated fat = 30.0 × 7.78 ÷ 100 = 2.3 g
Calories from fat = 13.2 × 9 = 119 kcal
Fat Daily Value = 13.2 ÷ 78 × 100 = 16.9%
Per 100 g Reference Table
| Form | Calories | Total fat | Saturated fat | Carbs | Protein |
|---|---|---|---|---|---|
| Raw | 553 kcal | 43.85 g | 7.78 g | 30.2 g | 18.2 g |
| Dry roasted | 574 kcal | 46.35 g | 8.01 g | 29.3 g | 17.3 g |
| Oil roasted | 580 kcal | 47.78 g | 8.29 g | 29.7 g | 16.8 g |

Portioning Tips & Common Mistakes
A kitchen scale is the most reliable way to measure cashews. Volume measures like cups and handfuls vary depending on whether the nuts are whole, broken, or roasted. Whole cashews in a measuring cup leave air gaps; the same cup can hold roughly 110 to 125 g depending on how tightly it is packed. The calculator uses 120 g per cup as a practical middle-ground estimate.
- Weigh cashews before seasoning. Honey-roasted or chocolate-covered cashews have added sugar and fat that the plain-nut values here do not capture.
- Remember that a handful is not a standardized amount. If you use the 30 g preset, check it against your scale once or twice to calibrate your eye.
- No-salt labels do not mean lower fat. Sodium content is separate from fat, so unsalted and lightly salted cashews have nearly identical fat values.
- If you are tracking macros, count oil-roasted cashews carefully: the added oil can increase total fat by roughly 4 g per 100 g compared with raw nuts.
Frequently Asked Questions
Are cashew nuts a high-fat food? Yes. Around 44–48% of the weight of a plain cashew is fat. The good news is that most of it is monounsaturated and polyunsaturated fat, the kinds associated with healthier cholesterol profiles when eaten in moderation. Still, because the calories are dense, portion control matters.
Why do dry-roasted cashews have more fat than raw ones? Dry roasting removes moisture, so the same weight contains a slightly higher concentration of fat. Oil roasting adds even more fat, because the nuts absorb some of the frying oil. If you prefer a lower-fat option among plain nuts, raw cashews are the way to go.
Does this calculator work for salted, honey-roasted, or flavored cashews? No. It assumes plain raw, dry-roasted, or oil-roasted cashews without added flavorings. Flavored products can have considerably different fat and calorie profiles, and many contain added sugars or oils that change the macros.
