One big sweet potato in your hand. A calorie app open on your phone. You search for how many calories in a large sweet potato has and get three different answers.
Here is the one that holds up.
A large sweet potato (about 180 g, or 6.3 oz) has 162 calories when baked with the skin on.
- Boiled and peeled, it has about 137 calories.
- Raw, it has about 155.
That answers the question of how many calories are in a large sweet potato. The rest of this guide explains why the numbers differ, how to get your own potato right, and how to make it work for your goal instead of against it.
Shakarkandi, kumara, or camote, the potato changes its name but not its math.

How Many Calories In A Large Sweet Potato? Why Do You See Three Answers
Nobody regulates the word “large” on a produce shelf.
The USDA values are listed per 100 g, so “large” is a label each website picks for itself. Most calorie sites settle on about 180 g, and this guide does too.
Four things change how many calories in a large sweet potato you actually get:
- The weight. A 150 g potato and a 300 g potato are both “large” to somebody.
- The cooking method. Raw, baked, and boiled, each carries its own calories per gram.
- The state you weigh it in. A potato loses water in the oven, so raw grams and baked grams are not the same potato.
- What goes on top. We will get to the butter.
The 162 Trap
Several popular pages that answer how many calories are in a large sweet potato say a 180 g raw one has 162 calories.
The arithmetic says otherwise.
The number 162 is 180 g multiplied by the baked value of 0.9 calories per gram. Raw sweet potato is 86 calories per 100 g, so 180 g raw comes to about 155.
Seven calories is a small gap. It still shows how easily raw and cooked numbers get mixed, and that is where most tracking errors start.
How Many Calories In a Large Sweet Potato By Cooking Method?
| Version | Calories per 100 g | Calories per gram | Calories in 180 g |
|---|---|---|---|
| Raw | 86 | 0.86 | 155 |
| Baked in skin | 90 | 0.90 | 162 |
| Boiled, no skin | 76 | 0.76 | 137 |
The per-100-gram values come from USDA data for sweet potato baked with skin, USDA data for sweet potato boiled without skin, and the raw value of 86 per 100 g. I multiplied them up to 180 g and rounded.
A Size Ruler: How Many Calories In A Large Sweet Potato At Any Weight
Your potato will not weigh exactly 180 g, so how many calories in a large sweet potato depends on your own scale.
So here is the ruler. Find the weight closest to yours and read across.
| Weight | Raw | Baked in skin | Boiled, no skin |
|---|---|---|---|
| 100 g | 86 | 90 | 76 |
| 114 g (medium) | 98 | 103 | 87 |
| 150 g | 129 | 135 | 114 |
| 180 g (large) | 155 | 162 | 137 |
| 250 g (extra large) | 215 | 225 | 190 |
| 300 g | 258 | 270 | 228 |
Look at the gap between 180 g and 250 g.
That is 63 calories for the same word, “large,” on the same shelf.
A kitchen scale settles it in ten seconds.
1 kg Sweet Potato Calories
A kilogram of raw sweet potato has about 860 calories.
Baked, it has about 900.
Boiled without skin, about 760.
One kilogram is roughly five and a half large potatoes, which makes it a handy number for meal prep or for checking a bulk bag against a week of eating.
How Much Sweet Potato is 200 Calories?
About 222 g if it is baked, which is 7.8 oz.
That is a little more than one large baked sweet potato. The math is simple: grams equal calories divided by calories per gram, so 200 divided by 0.9 gives 222.
Here is the same idea for other targets.
| Calorie target | Raw | Baked in skin | Boiled, no skin |
|---|---|---|---|
| 100 calories | 116 g | 111 g | 132 g |
| 200 calories | 233 g | 222 g | 263 g |
| 300 calories | 349 g | 333 g | 395 g |
| 400 calories | 465 g | 444 g | 526 g |
How Many Calories In a Large Sweet Potato With Skin, Without Skin, Baked, or Boiled?
Four searches, one potato. Here is how each one lands.
How many calories in a large sweet potato with skin?
Baked with the skin on, a large sweet potato has about 162 calories.
The fiber is 5.9 g, the highest of the versions in this guide.
How many calories in a large sweet potato with no skin?
Boiled and peeled, the same 180 g has about 137 calories.
That is 25 calories lower. Most of the gap probably comes from the cooking method, not the peel. Baking drives water out of the flesh, and boiling leaves it wetter, so each gram holds fewer calories.
The skin is a thin layer. Peeling it saves almost no energy and costs you some fiber: 5.9 g in the baked large potato against 4.5 g in the boiled, peeled one. The cooking method plays a part in that difference too.
How many calories in a large sweet potato baked
About 162 calories if you weighed 180 g of baked flesh.
If you weighed the potato raw and then baked it, expect closer to 155, because the raw weight belongs with the raw value of 86 per 100 g.
The rule that keeps your tracking honest is simple. Use the cooked value for cooked weight and the raw value for raw weight. Do not switch halfway through the week.
1 boiled sweet potato calories
A boiled, peeled sweet potato of 150 g comes to about 114 calories.
A large 180 g one comes to about 137.
Boiling is the lowest-calorie way to cook a sweet potato, which is why it suits people who eat it plain.
How Many Calories in a Large Sweet Potato With Butter
The potato is the quiet part of this meal.
The butter is the loud part.
A tablespoon of butter has 102 calories and 11.5 g of fat. A teaspoon is a third of that, around 34 calories.
The large baked potato underneath has only about 0.3 g of fat.
| Topping on a large baked sweet potato | Added calories | Total calories |
|---|---|---|
| Plain | 0 | 162 |
| 1 teaspoon of butter | 34 | 196 |
| 1 pat of butter | 36 | 198 |
| 1 tablespoon of butter | 102 | 264 |
| 2 tablespoons of butter | 204 | 366 |
Read the last row twice.
Two spoons of butter are more than double the calories of the potato itself.
A single tablespoon adds about 63% to what the potato brings. The extra calories are almost all fat, since butter carries next to no carbs or protein.
If you love the butter, keep it. Just measure it with a spoon instead of the eye, and count it in your app as its own line.
How Many Carbs Are in a Large Sweet Potato, and How Much Protein?
Before the macros, remember that how many calories in a large sweet potato (162 baked) comes down to carbs: about 90% of its calories come from them.
Protein is where it is weak.
| Per large sweet potato (180 g) | Baked with skin | Boiled, no skin |
|---|---|---|
| Calories | 162 | 137 |
| Carbohydrate | 37 g | 32 g |
| Net carbs (carbs minus fiber) | 31 g | 27 g |
| Fiber | 5.9 g | 4.5 g |
| Natural sugar | 11.7 g | 10.3 g |
| Protein | 3.6 g | 2.5 g |
| Fat | 0.3 g | 0.2 g |
These values are the USDA per-100-gram figures from the sources below, scaled to 180 g.
What this means for your plate
The carbs are real, so count them if you track carbs.
The fiber is real too, and it is the reason the potato feels more filling than its calories suggest.
The protein is small. A large sweet potato gives about 3.6 g, which is around 9% of its calories.
So do not expect it to carry your protein for the meal. Build the protein around it, and the next section shows how.
How Many Calories In a Chicken Breast, And The Plate That Fixes the Protein?
Chicken is the classic partner, so let us put real numbers on it.
According to a chicken breast calorie breakdown, cooked skinless breast has 165 calories and 31 g of protein per 100 g. Raw, skinless breast is lower per gram, around 110 to 120 calories per 100 g, because it still holds its water. USDA data for raw skinless breast lists 110.
| Chicken breast, per 100 g | Calories | Protein | Fat |
|---|---|---|---|
| Cooked, skinless | 165 | 31 g | 3.6 g |
| Cooked, with skin | 197 | 30 g | 7.8 g |
| Raw, skinless | 110 to 120 | 23 g | 2 to 2.6 g |
A whole cooked breast of 174 g has about 284 calories. A 170 g (6 oz) cooked portion has about 279 calories and 53 g of protein.
Now the comparison that matters.
A large baked sweet potato has 162 calories and 3.6 g of protein. A 100 g portion of cooked chicken has 165 calories and 31 g of protein.
The calories match. The protein is not even close.
Three plates, with the math done for you
| Plate (all weights cooked) | Calories | Protein |
|---|---|---|
| Large boiled sweet potato + 100 g chicken | 302 | 34 g |
| Large baked sweet potato + 100 g chicken | 327 | 35 g |
| Large baked sweet potato + 170 g chicken | 441 | 57 g |
Add a teaspoon of butter to any plate, and it grows by about 34 calories.
The second plate is 327 calories, which is about 16% of a 2,000-calorie reference day, with 35 g of protein. That is a meal that fills you up without drama.
How Many Calories in A Large Sweet Potato, And How Does It Compare
A baked russet potato, flesh and skin, has 95 calories per 100 g. It also has 2.6 g of protein, 21.4 g of carbs, and 2.3 g of fiber per 100 g.
At the same 180 g as our large sweet potato, that is about 171 calories, 4.7 g of protein, 38.5 g of carbs, and 4.1 g of fiber.
The chart shows how many calories in a large sweet potato compare with a russet and with chicken.
The sweet potato is about 9 calories lighter than the russet, with more fiber (5.9 g against 4.1 g). The russet has a little more protein.
Neither one is a trick. Pick the one you enjoy and weigh it.
The real jump on the chart is the chicken. Same weight, nearly double the calories, and about fifteen times the protein. That is why potato and chicken work as a pair.
Is sweet potato OK for weight loss?
Yes, with one condition.
The condition is that the potato stays a potato and does not turn into a dessert.
Fiber and water make a sweet potato filling for its calories, which may help you eat less across the day. Healthline’s review of the evidence says the same, and it adds the honest part: weight loss still comes from a calorie deficit, and big portions, added fat, or sugary sides can push a sweet potato meal into weight gain territory.
My read is that the potato is rarely the problem.
The 264-calorie butter version is the problem. So is the marshmallow casserole.
A plain baked or boiled potato next to a lean protein is an easy swap for something far denser.
How to make it work, step by step
- Weigh it. The answer to how many calories are in a large sweet potato starts with real grams, so use the size ruler above.
- Boil it or bake it. Both are low-calorie, and boiling is the lowest at about 137 calories for a large one.
- Eat the skin if you like it. It keeps the fiber up.
- Put protein next to it, such as 100 g of cooked chicken breast for 35 g of protein on the plate.
- Measure the butter with a teaspoon, and log it as its own line.
Is it Okay to Eat One Large Sweet Potato?
For most people, yes.
At 162 calories, one large baked sweet potato is about 8% of a 2,000-calorie reference day. It also brings 5.9 g of fiber with it.
If you manage diabetes, count its 37 g of carbohydrates like any other carb serving, and ask your dietitian how it fits your plan.
If you have any medical condition that limits your food choices, check with your doctor or dietitian first. This guide shares nutrition data, and it does not replace their advice.
5 Mistakes That Change How Many Calories In a Large Sweet Potato You Log
Most people do not miscount by a lot. They miscount a little, every day.
- Mixing raw and cooked. Logging 180 g of raw potato against the baked entry adds 7 calories. Across a kilogram, it adds about 40.
- Trusting the word “large”. A 250 g baked potato is 225 calories, and a 180 g one is 162. The label hides a 63-calorie gap.
- Forgetting the butter. One tablespoon is 102 calories, which is 63% on top of the potato.
- Picking the wrong database entry. A frozen baked sweet potato is listed at 100 calories per 100 g, against 90 for a fresh baked one. Check that the entry matches what is on your plate.
- Judging potatoes by calories alone. A sweet potato and a russet land within 9 calories of each other, so the deciding factors are fiber, taste, and what you pair them with.
Weigh your own potato once, write the grams on a sticky note, and multiply by 0.9 if it is baked.
That one habit answers how many calories in a large sweet potato better than any size label on a supermarket shelf.
