Butter is almost pure fat — about 80% fat by weight — which makes it calorie-dense but also simple to understand nutritionally. The numbers don't lie, they just surprise people who've been eyeballing tablespoons.

Butter calories by serving size
Butter is sold in sticks, tubs, and blocks — but we eat it in tablespoons, teaspoons, and casual swipes. Here's the full reference table:
| Serving | Weight | Calories | Total Fat | Saturated Fat |
|---|---|---|---|---|
| 1 pat / chip (restaurant portion) | 5g | 36 kcal | 4g | 2.5g |
| 1 teaspoon | 4.7g | 34 kcal | 3.8g | 2.4g |
| 1 tablespoon | 14.2g | 102 kcal | 11.5g | 7.3g |
| 2 tablespoons | 28.4g | 204 kcal | 23g | 14.6g |
| ¼ stick (2 tbsp) | 28g | 200 kcal | 22.7g | 14.4g |
| ½ stick (4 tbsp) | 56g | 405 kcal | 45.5g | 28.9g |
| 1 stick (8 tbsp) | 113g | 810 kcal | 92g | 58g |
| 100g | 100g | 717 kcal | 81g | 51g |
Butter macros — what's actually in it
Butter is essentially a concentrated dairy fat. Its macro profile is as simple as it gets: almost entirely fat, trace amounts of everything else.
| Nutrient | Per 100g | Per 1 tbsp (14.2g) |
|---|---|---|
| Calories | 717 kcal | 102 kcal |
| Total fat | 81.1g | 11.5g |
| — Saturated fat | 51.4g | 7.3g |
| — Monounsaturated fat | 21.0g | 3.0g |
| — Polyunsaturated fat | 3.0g | 0.4g |
| Protein | 0.6g | 0.1g |
| Carbohydrates | 0.1g | 0g |
| Cholesterol | 215mg | 31mg |
| Vitamin A | 684 µg (76% DV) | 97 µg (11% DV) |
| Vitamin D | 1.5 µg | 0.2 µg |
Butter has essentially zero carbohydrates, making it a staple in ketogenic diets. Its protein content is negligible — butter is churned from cream after most of the milk proteins and lactose have been separated off. What remains is fat, water (around 16–18%), and trace micronutrients, particularly vitamin A from the milk fat globules.
Salted vs unsalted butter — same calories, different sodium
One of the most common questions: is salted butter higher in calories than unsalted? The answer is no. The only meaningful difference between salted and unsalted butter is the sodium content.
| Type | Calories per tbsp | Fat per tbsp | Sodium per tbsp |
|---|---|---|---|
| Unsalted butter | 102 kcal | 11.5g | ~2mg |
| Salted butter | 102 kcal | 11.5g | ~90mg |
The salt added to salted butter is typically around 1.6–2% of total weight — enough to make a noticeable flavour difference but not enough to affect calorie count. For calorie tracking, use the same number regardless of which type you're using. If you're watching sodium intake, however, the difference adds up: using 3 tablespoons of salted butter in a recipe adds ~270mg of sodium from the butter alone.
Butter vs other fats — calories per tablespoon
Butter is often compared to other cooking fats for both calorie content and fat type. Here's how one tablespoon stacks up:
| Fat | Calories / tbsp | Total Fat | Primary Fat Type | Best For |
|---|---|---|---|---|
| Butter | 102 kcal | 11.5g | Saturated (63%) | Baking, flavour, finishing |
| Ghee (clarified butter) | 112 kcal | 12.7g | Saturated (65%) | High-heat cooking, South Asian cuisine |
| Olive oil (extra virgin) | 119 kcal | 13.5g | Monounsaturated (73%) | Dressings, low-heat sautéing |
| Coconut oil | 117 kcal | 13.6g | Saturated (87%) | Baking, medium-heat cooking |
| Vegetable oil (canola) | 124 kcal | 14g | Monounsaturated (62%) | High-heat frying, neutral flavour |
| Margarine (regular) | 102 kcal | 11.5g | Mixed (variable) | Spreading, baking substitute |
Interesting takeaway: butter is actually one of the lower calorie cooking fats per tablespoon because it contains 16–18% water, which adds weight without adding calories. Oils are pure fat by weight, so they pack more calories per gram. That said, the practical difference between fats in cooking is often negligible — the main consideration is the fat type (saturated vs. unsaturated) and smoke point.
How butter calories add up fast in real cooking scenarios
The reason butter is a common tracking blind spot: it goes into meals invisibly. You don't put a pat on your plate — it's already in the pan, in the sauce, spread on bread before you eat it. Here are realistic scenarios:
| Cooking scenario | Butter used | Calories added |
|---|---|---|
| Buttering 2 slices of toast (1 pat each) | 2 pats / 10g | 72 kcal |
| Sautéing vegetables (2 tbsp in pan) | 2 tbsp / 28g | 204 kcal |
| Scrambling 2 eggs (1 tsp) | 1 tsp / 4.7g | 34 kcal |
| Pan sauce (restaurant portion, ~1 tbsp) | 1 tbsp / 14g | 102 kcal |
| Mashed potatoes (2 tbsp per serving) | 2 tbsp / 28g | 204 kcal |
| Baking a cake (½ stick in recipe, 8 servings) | ~14g per slice | ~100 kcal per slice |
| Restaurant dinner roll with "a little butter" | ~1.5 tbsp estimated | ~153 kcal |
A typical breakfast (eggs in butter + buttered toast) can easily include 200–250 kcal from butter alone — before counting the eggs or the bread. This isn't a reason to avoid butter; it's a reason to measure it.
How to track butter accurately
Use a kitchen scale, not measuring spoons
A "tablespoon" of butter varies significantly depending on how firm the butter is and how you scoop it. Cold butter from the fridge in a tablespoon measure weighs about 14g. Soft, room-temperature butter mounded in a tablespoon can weigh 18–20g. That's a 40% calorie difference from the same spoon. Weighing on a scale takes 2 seconds and is far more accurate.
Account for butter left in the pan
Not all butter used in cooking is consumed. Some evaporates, some stays on the pan. A general rule: if you cook and then eat everything from the pan (like scrambled eggs), count all the butter. If you sauté vegetables and drain them, discount about 20–30% of the butter — some remains in the pan. For practical tracking, counting all of it is the safer approach and avoids under-logging.
Use the weight in grams, not tablespoons, in your app
Most calorie tracking apps let you enter the amount in grams rather than tablespoons. This is more accurate because the calorie database entries are based on exact weights. Search "butter" and select "100g serving," then type the actual grams you weighed. This avoids the tablespoon measurement ambiguity entirely.
Frequently asked questions
How many calories are in a tablespoon of butter?
One tablespoon of butter (14.2g) contains approximately 102 calories, 11.5g of fat (7.3g saturated fat), 0.1g of protein, and effectively zero carbohydrates. Salted and unsalted butter are identical in calorie content — the only difference is about 90mg of sodium per tablespoon in salted varieties.
How many calories are in a pat of butter?
A standard pat or chip of butter (5g) contains approximately 36 calories. Restaurant butter pats range from 5g to 7g, so they come in at 36–50 calories each. If you use two pats on bread before a meal, that's already 72–100 calories from butter alone before you start eating.
How many calories are in a stick of butter?
One US stick of butter (113g / 4 oz / 8 tablespoons) contains approximately 810 calories, 92g of total fat (58g saturated), and negligible protein and carbohydrates. Half a stick is around 405 calories. If a baking recipe calls for a full stick and makes 8 servings, each serving contains roughly 101 calories from the butter alone.
How many calories are in 100g of butter?
100g of butter contains approximately 717 calories, 81g of total fat (51g saturated fat), 0.6g of protein, and 0.1g of carbohydrates. It also provides around 215mg of cholesterol and is a good source of vitamin A (approximately 684 µg, or about 76% of the daily value).
Is butter worse than olive oil for calories?
Slightly the opposite — butter has fewer calories per tablespoon than olive oil. Butter = ~102 kcal/tbsp; olive oil = ~119 kcal/tbsp. The difference exists because butter contains 16–18% water, while oil is 100% fat. That said, the calorie difference is small enough to be nutritionally irrelevant for most people. The more important distinction is fat type: olive oil is predominantly monounsaturated (heart-healthier profile), while butter is predominantly saturated.
