How Many Calories Are In A Cashew? | Quick Nut Facts

One raw cashew has about 9 calories; one ounce (roughly 18 pieces) of cashews has about 157 calories.

Cashew Calories Explained

Cashews are buttery seeds that deliver energy in a tiny package. The calorie number you’ll see most often comes from lab averages: one ounce of raw cashew kernels (28 grams, about 18 pieces) provides about 157 calories, with roughly 12.5 grams fat, 8.6 grams carbs, and 5.2 grams protein. Those figures are listed in MyFoodData and sourced directly from USDA FoodData Central.

So what about a single piece? Raw cashews average around 1.5–1.7 grams each. Using the 553 kcal per 100 grams baseline for raw cashews, one piece lands near nine calories. Grab a quick five and you’re around 45 calories. Double that handful and you’re in snack territory.

Calories In Cashews By Portion And Style

Here’s a quick reference you can scan before you pour a bowl. It sticks to common portions and the most typical styles you’ll meet on labels.

Cashew Item Portion Calories
Raw kernels 1 oz (28 g) ~157 kcal
Dry-roasted, unsalted 1 oz (28 g) ~157–163 kcal
Oil-roasted, unsalted 1 oz (28 g) ~164–170 kcal
Raw kernels 100 g ~553 kcal
Cashew butter 1 tbsp (16 g) ~94–100 kcal
Cashew milk (unsweetened) 1 cup (240 ml) ~25–40 kcal

You’ll see small swings between brands. Oil-roasted batches pick up a little extra energy from the added fat. Dry-roasted lots tend to match raw kernels. For raw values and minerals, the best reference is USDA FoodData Central, which lists raw cashews at about 553 kcal per 100 grams.

Snacks fit better once you set your daily calorie needs and place cashews with intent—say, 100–200 snack calories beside lunch.

How Many Calories Are In A Cashew Per Piece?

Count one raw piece at about nine calories. That estimate comes from the 553 kcal per 100 grams baseline divided by typical kernel weight. Cashews aren’t uniform, so you’ll hit a range. Small pieces near 1.2 grams fall closer to seven calories. Large whole kernels near two grams can climb to eleven calories.

Want a quick trick without a scale? Weigh ten pieces once, note the grams, and keep that number. Multiply grams by 5.53 to get calories. It’s fast and consistent across a bag from the same brand.

Raw Vs. Roasted: What Changes?

Roasting shifts moisture and flavor. Dry-roasted cashews usually stay close to raw for calories per ounce. Oil-roasted versions soak up surface oil, which bumps calories by a few digits per ounce. Salt doesn’t add energy, but it can nudge you to eat more. If you like roast, portion a ramekin before you snack.

Micros stay friendly either way. Per ounce, raw cashews provide about 83 mg of magnesium and 0.62 mg of copper along with potassium and phosphorus—numbers you can cross-check on the MyFoodData cashew page. That mineral mix is why small servings satisfy many eaters.

Cashew Calories By Count

Use this table when you’re building a snack plate or topping oatmeal. Counts reflect average raw kernels.

Cashews Approx. Grams Approx. Calories
5 pieces ~8 g ~44 kcal
10 pieces ~16 g ~88 kcal
15 pieces ~24 g ~132 kcal
18 pieces (about 1 oz) ~28 g ~157 kcal
20 pieces ~32 g ~177 kcal
30 pieces ~48 g ~265 kcal

Portions That Work In A Day

Think in snack bands. Around 50–100 calories works when you only want a crunch between meals. That’s six to twelve raw pieces. A classic one-ounce handful lands near 150–170 calories, which fits many lunch plates. If you’re cooking, cashews in stir-fries, creamy sauces, or pesto can move calories fast. Measure the nuts before blending so the sauce doesn’t outrun your plan.

Smart Add-Ins And Traps

Plain cashews pair with fruit, dark chocolate, and yogurt. Sweet glazes and trail mixes stack sugar and oils along with the nuts. Scan labels and watch serving size. A teaspoon of honey adds about 21 calories; a tablespoon of chocolate chips adds around 70. These tiny extras double a small snack before you notice.

How To Weigh And Store Cashews

For repeatable counts, use a small digital scale and a dish. Pour to 28 grams for the classic serving, or build a custom snack in five-gram steps. Store kernels in an airtight jar in a cool cupboard. For longer stretches, keep them in the fridge or freezer to protect the delicate fats from going stale.

Are Cashew Calories Worth It?

Cashews carry mostly unsaturated fats and a touch of plant protein. They’re calorie dense, so portion control matters, but the mix of fat, fiber, and minerals helps a small serving feel steady. USDA-based numbers show the profile: about 12.5 g fat, 8.6 g carbs, and 5.2 g protein per ounce, plus magnesium, copper, and zinc. If sodium is a concern, pick unsalted and season your bowl yourself.

Building Meals With Cashews

Use a tablespoon or two to add crunch to salads or grain bowls. Blend a half cup with water and a pinch of salt for a quick sauce that coats vegetables or noodles. For desserts, toasted cashews pair with sliced mango, berries, or cocoa powder. Small amounts go a long way in both texture and calories.

The Keyword Question, Answered Cleanly

If you came here asking how many calories are in a cashew, here’s the tidy answer again: one piece is about nine calories, and one ounce—roughly eighteen pieces—lands around 157 calories when raw, a tick higher if oil-roasted. That line comes from USDA FoodData Central and aligns with the MyFoodData summary.
