How Many Calories Are In 100G Potato? | Clear Nutrition Facts

Calories In 100 Grams Of Potato: Raw Vs Cooked

Let’s pin down the numbers first. Per 100 grams, plain potato sits around three tight bands: raw ~77 kcal, boiled without salt ~86 kcal, and baked with the skin ~93 kcal. These figures come from lab-based datasets and reflect potatoes cooked without added fats. The moment oil, butter, or cheese enter the pan, the energy per bite climbs fast.

Why The Numbers Shift With Heat

Water leaves during dry-heat cooking. That concentrates starch and nudges calories per 100 g upward. Moist-heat methods like boiling add no fat and often hold more water, so the same weight carries a touch fewer calories than dry-cooked spuds. Keep seasonings simple if you want the scale to match the tables below.

Quick Nutrition Snapshot Per 100 Grams

The table below compresses the most asked-about data into one place. Values are rounded so you can eyeball a meal without a calculator.

Preparation	Kcal Per 100 g	Macro Snapshot
Raw (flesh + skin)	~77	~17.7 g carbs, ~2.1 g protein, ~0.1 g fat
Boiled (no skin, no salt)	~86	~20.2 g carbs, ~1.7 g protein, ~0.1 g fat
Baked (with skin, no salt)	~93	~21.4 g carbs, ~2.5 g protein, ~0.1 g fat

How These Values Were Calculated

Each row is anchored to public nutrient datasets. On the raw entry, the base listing reports 58 kcal for a 75 g half-cup; scaled to 100 g that yields about 77 kcal. On the boiled entry, the same dataset shows 67 kcal for 78 g; scaled to 100 g that’s roughly 86 kcal. For baking, a 173 g medium potato sits near 161 kcal; scaled to 100 g it’s close to 93 kcal. You’ll see slight swings across varieties, but these anchors are reliable for home planning (raw reference • boiled reference • baked reference).

Peel, Cut, And Water Content

Skins add fiber and a little protein for minimal calories. Leaving them on nudges satiation, which helps you feel full on fewer bites. That’s why many dietitians pair potatoes with skins and lean toppings. Public guidance also places potatoes in the starchy carbohydrate group and suggests leaving skins for more fiber, as shown in the Eatwell Guide.

Portion Sense Without Overthinking

You don’t need a scale every night. Once you learn a few visual cues, you can estimate 100 grams within a small margin. The quick guide below maps common pieces to grams and calories. Season with herbs and a pinch of salt, and you’ll stay close to plan.

Potatoes slide into a balanced plate once you’ve set your daily calorie needs; then it’s just portion and prep.

Handy Visual Equivalents

Use these conversions when you don’t have a scale. They’re meant to keep weeknight meals simple and steady.

Serving	Approx. Weight (g)	Approx. Kcal
Half cup diced (raw)	~75	~58
Half cup boiled pieces	~78	~67
Medium baked with skin	~173	~161

Make The Numbers Work At The Table

Keep Cooking Fat Under Control

Oil contributes ~119 kcal per tablespoon. Brush, spray, or toss with a teaspoon and you’ll shave big calories off roast potatoes. Preheat the pan, space the pieces, and use a light, high-heat oil to get a crisp edge without a heavy pour.

Smart Pairings That Fill You Up

Spuds feel extra filling next to lean protein and non-starchy veg. Try baked potato with tuna and a sharp salad, or boiled mini potatoes tossed with yogurt-mustard dressing and chives. Fiber from the skin plus protein from the plate turns a small portion into a satisfying meal.

Sodium, Potassium, And Balance

Plain potatoes are naturally low in sodium and a source of potassium. You can season boldly with herbs, pepper, garlic, and vinegar while staying light on salt. For baseline carbohydrate guidance and starchy food placement on a healthy plate, refer to official pages like the NHS overview on starchy foods.

Variations You’ll See In The Wild

Different Types, Small Swings

White, red, and russet potatoes sit near each other calorie-wise per 100 g. Texture differs more than energy. Waxy types hold shape when boiled; floury types bake fluffy. Pick the cooking style first, then choose the variety that suits it.

Cut Size Changes Intake

Smaller pieces expose more surface area, which invites more oil during roasting. If you want crisp edges without a big calorie bump, parboil wedges, steam-dry, then roast on a hot tray with a light spray. Flip once. Pull when edges brown.

What About Mash?

Mash is as lean as the mix-ins. Start with boiled potatoes and add warm milk and a pat of butter, not a stick. Whisk in yogurt for creaminess, or olive oil for a softer finish. The base potatoes are still near ~86 kcal per 100 g; toppings set the rest.

Putting It Into Practice Tonight

A Simple Boiled-Then-Roast Method

1) Cut potatoes into chunks. 2) Boil in salted water until just tender. 3) Drain and shake the pot to rough the edges. 4) Spread on a hot tray, mist with a teaspoon or two of oil in total, and roast at high heat. 5) Season with herbs and lemon. Crisp outside, soft inside, and calories stay honest.

When You Need Speed

Microwave whole potatoes (pierced) until nearly done, then finish in a skillet with a splash of water and a light oil spray. You’ll get stovetop browning in minutes without soaking up fat.

Frequently Checked Facts, In Plain English

Are Potatoes “Good” Or “Bad” For A Diet?

They’re a flexible starch. Keep portions near 100–150 g cooked per person at dinner, match with lean protein, and choose moist-heat or dry-heat with minimal added fat. That pattern fits most calorie targets and keeps meals satisfying.

Do Skins Matter?

Yes—skins carry fiber for almost no energy cost. Leave them on when you can. It helps with fullness and adds texture. That’s why you’ll see public diet guides suggest keeping skins where possible.

How To Read Labels And Databases Quickly

Scan serving size, then scale to 100 g if needed. Databases often show a half-cup or medium potato by default; switch the serving to 100 g or use the math shown above. Authoritative datasets such as USDA FoodData Central and curated summaries like MyFoodData list raw, boiled, and baked entries separately so you can match your method.

Field Notes For Cooks Who Log Calories

Batch Cooking Without Guesswork

Weigh the raw batch, cook it, then weigh the cooked batch. Divide cooked weight by portions and log per-portion grams against the tables. If you added oil, log the exact amount and split across servings. That’s the surest way to stay consistent through the week.

Seasonings That Don’t Tip The Scale

Lemon juice, vinegar, mustard, chili flakes, garlic, thyme, rosemary, and smoked paprika bring punch without oil or cheese. Finish with chopped parsley and a squeeze of lemon for brightness.

One More Look At The Numbers

Here’s a final mini-recap linking cooking style with energy density. Use it to set sides that fit your day’s target.

Cooking Style	Per 100 g	What It Means
Boiled, drained	~86 kcal	Leanest cooked option; great for salads and mash
Baked, skin on	~93 kcal	Dry heat concentrates; still low for how filling it is
Roasted with oil	Varies	Every Tbsp oil adds ~119 kcal to the pan total

Wrap-Up You Can Use Tonight

Count on ~77 kcal per 100 g raw, ~86 kcal when boiled, and ~93 kcal when baked with the skin. Keep fats light, keep portions steady, and round flavors with herbs and acid. That’s how you enjoy potatoes and still hit your target.
