When I first started paying attention to what I eat, butter was one of those foods that surprised me with its calorie content. A simple pat of butter on toast seemed harmless until I learned it packed around 36 calories in that tiny portion. Understanding the caloric content of butter is important for anyone managing their diet, whether you're trying to lose weight, maintain your current weight, or just make better food choices.
Butter is a staple in many kitchens worldwide, but its high calorie density means that small amounts can quickly add up. In this comprehensive guide, we'll break down exactly how many calories are in different serving sizes of butter, compare it to other fats, and help you make informed decisions about including butter in your diet.
Calories in Butter by Serving Size
How Many Calories Are in a Teaspoon or Tablespoon of Butter?
The calorie content of butter varies slightly depending on the brand and type, but here are the standard measurements you need to know:
1 teaspoon (5 g): ~34–36 kcal
A single teaspoon of butter contains about 34 to 36 calories. This might not seem like much, but when you consider that many people use multiple teaspoons throughout the day, these calories can accumulate quickly.
1 tablespoon (14 g): ~100–102 kcal
One tablespoon of butter contains approximately 100 to 102 calories. This is the most commonly used measurement in cooking and baking. I've found that most recipes calling for butter use tablespoon measurements, so this number becomes quite important when calculating the total calories in your homemade dishes.
1 pat (~5 g): ~36 kcal
A standard butter pat, like those served at restaurants, contains about 36 calories. These small portions might seem insignificant, but they're roughly equivalent to a teaspoon of butter.
How Many Calories Are in 100 Grams of Butter?
100 g of butter: ~717 kcal
One hundred grams of butter contains approximately 717 calories, making it one of the most calorie-dense foods in the average kitchen. To put this in perspective, 100 grams is roughly equivalent to 7 tablespoons of butter.

Does Melted Butter Have Different Calories?
Many people wonder whether melting butter changes its caloric content. The answer is no – melted butter has the same caloric density as solid butter. When butter melts, only its physical state changes, not its energy content.
However, there's an important practical consideration: melted butter can be easier to measure inaccurately. When I melt butter for cooking, I often find myself using more than I intended because liquid butter spreads differently than solid butter. The volume might appear different, but the calories per gram remain constant at about 7.2 calories per gram.
Macronutrients & Full Nutrition Breakdown
Fat, Saturated Fat, and Cholesterol
Butter is almost entirely fat, which explains its high calorie content. Here's what you'll find in one tablespoon of butter:
~12 g total fat/tbsp, ~7 g saturated fat
Each tablespoon of butter contains approximately 12 grams of total fat, with about 7 grams being saturated fat. This means that roughly 58% of butter's fat content is saturated, which is significant when considering daily saturated fat limits.
Cholesterol ~31 mg/tbsp
Butter also contains about 31 milligrams of cholesterol per tablespoon. For context, dietary guidelines suggest limiting cholesterol intake to less than 300 mg per day for healthy adults.
Vitamin A, D, E, K – contributions and %DV
Despite its high calorie and fat content, butter does provide some nutritional benefits. It's a good source of fat-soluble vitamins:
- Vitamin A: One tablespoon provides about 11% of the daily value
- Vitamin D: Small amounts, roughly 1-2% of daily value
- Vitamin E: Minimal amounts
- Vitamin K: About 1% of daily value
These vitamins are essential for various body functions, including immune system support, bone health, and blood clotting.
Sodium and Salt Content
Do Unsalted and Salted Butter Have Different Calorie Counts?
The calorie difference between salted and unsalted butter is negligible – both contain essentially the same number of calories per serving. However, the sodium content varies dramatically:
- Unsalted butter: Less than 5 mg sodium per tablespoon
- Salted butter: 80-90 mg sodium per tablespoon
From my experience cooking with both types, I prefer unsalted butter for baking because it gives me better control over the final taste and sodium content of my dishes. The calorie count remains the same regardless of which type you choose.
Butter vs Other Fats – Calorie Comparisons
Calories in Margarine vs Dairy Butter
Margarine: ~85 kcal/tbsp
Dairy butter: ~102 kcal/tbsp
Which Has Fewer Calories: Butter or Margarine?
Margarine typically contains fewer calories than butter, with about 85 calories per tablespoon compared to butter's 102 calories. This 17-calorie difference might seem small, but it can add up over time, especially if you use these fats frequently in cooking or baking.
However, calories aren't the only consideration. Margarine often contains trans fats or highly processed oils, while butter is a more natural product. The choice between them depends on your individual health goals and dietary preferences.
Is Butter Higher in Calories Than Olive Oil?
Olive oil: ~119 kcal/tbsp
Butter: ~102 kcal/tbsp
Interestingly, olive oil contains more calories per tablespoon than butter – about 119 calories compared to butter's 102 calories. This surprised me when I first learned it, as olive oil is often considered the healthier option.
The key difference lies not in the calorie content but in the types of fats. Olive oil contains primarily monounsaturated fats, which are considered heart-healthy, while butter is high in saturated fats. Both are calorie-dense, so portion control matters regardless of which you choose.
Does Butter or Peanut Butter Have More Calories?
Peanut butter: ~94–100 kcal/tbsp
Peanut butter and regular butter have surprisingly similar calorie contents, with peanut butter containing about 94-100 calories per tablespoon. However, their nutritional profiles are quite different:
- Butter is slightly higher in total fat content
- Peanut butter provides more protein (about 4 grams per tablespoon)
- Peanut butter contains fiber, while butter contains none
- Peanut butter offers more vitamins and minerals, including niacin, magnesium, and phosphorus
Calories in Clarified, Organic, and Plant-Based Butter
Does Clarified Butter (Ghee) Have More Calories?
Ghee: ~112 kcal/tbsp – slightly more than regular butter
Clarified butter, or ghee, contains slightly more calories than regular butter at about 112 calories per tablespoon. This increase occurs because ghee has had its water and milk solids removed, concentrating the fat content.
I've been using ghee more frequently in my cooking because it has a higher smoke point and longer shelf life than regular butter. While it does contain more calories, the difference is relatively small, and ghee offers some unique benefits for high-heat cooking.
Does Organic Butter Have Fewer Calories Than Regular Butter?
There's no significant difference in calorie content between organic and conventional butter. Both contain approximately the same amount of fat and calories per serving. The main differences lie in production methods and potentially in micronutrient content.
Organic butter may contain slightly higher levels of certain beneficial compounds like conjugated linoleic acid (CLA) and omega-3 fatty acids, but these differences don't significantly impact the calorie count.
Is Plant-Based Butter Lower in Calories Than Dairy Butter?
Usually slightly lower (~80–90 kcal/tbsp); varies by brand
Most plant-based butter alternatives contain fewer calories than dairy butter, typically ranging from 80 to 90 calories per tablespoon. However, this varies significantly by brand and formulation.
Some plant-based butters achieve lower calorie counts by incorporating more water or air into their products. Others use different oil blends that may result in slightly different caloric densities. Always check the nutrition label, as some premium plant-based butters can have calorie counts similar to dairy butter.
Impact of Butter Calories on Diet and Health
Does Butter Contribute to Weight Gain?
Yes, butter can contribute to weight gain if consumed in excess, primarily because it's high in calories and saturated fat. Weight gain occurs when you consistently consume more calories than you burn, and butter's calorie density makes it easy to create a caloric surplus without realizing it.
However, butter itself doesn't directly cause weight gain – overconsumption of calories from any source will lead to weight gain. The key is understanding portion sizes and accounting for butter's calories in your daily intake.
Can I Eat Butter While on a Diet?
Absolutely – you can include butter in your diet while trying to lose weight. The key is moderation and ensuring it fits within your daily calorie and macronutrient goals.
I've successfully included small amounts of butter in my diet during weight loss phases by being mindful of portions and balancing it with other nutrients. One tablespoon of butter can add richness and satisfaction to a meal, potentially helping you feel more satisfied and less likely to need more food later.
Are Butter Calories Healthy?
Butter calories come with both benefits and drawbacks. While butter is nutritionally dense and provides fat-soluble vitamins, it's also high in saturated fat, which can raise cholesterol levels in some people.
Butter contains several beneficial compounds:
- Fat-soluble vitamins (A, D, E, K)
- Conjugated linoleic acid (CLA), which may have anti-inflammatory properties
- Short-chain fatty acids that can benefit gut health
- Natural antioxidants like beta-carotene (especially in grass-fed butter)
However, the high saturated fat content means butter should be consumed in moderation as part of a balanced diet.
Does Eating Butter in the Morning Affect Energy Levels?
Eating butter in the morning can provide sustained energy because fat slows digestion and provides a steady source of fuel. However, for the best energy effects, I recommend pairing butter with protein and fiber.
For example, butter on whole grain toast with eggs provides a more balanced energy release than butter alone. The fat in butter helps slow the absorption of carbohydrates, preventing rapid blood sugar spikes and crashes.
How Much Butter Is Reasonable to Eat in a Day?
According to dietary guidelines, saturated fat should make up less than 10% of your total daily calories. For someone eating 2,000 calories per day, this means limiting saturated fat to about 22 grams daily.
Since one tablespoon of butter contains about 7 grams of saturated fat, consuming around one tablespoon per day (or slightly less) fits within these guidelines for most people. This amount provides about 100 calories and represents roughly one-third of the recommended daily saturated fat limit.
However, this recommendation should be personalized based on:
- Individual health conditions (heart disease, high cholesterol)
- Overall diet quality and other sources of saturated fat
- Personal fitness goals and activity levels
- Individual tolerance and preferences
Which Type of Butter Has the Least Calories?
Among traditional butter types (fresh, unsalted, salted), the calorie differences are minimal – all contain roughly the same number of calories per gram.
Whipped or light butter has the lowest calories per tablespoon, containing about 47–70 kcal. These products achieve lower calorie counts by incorporating air or water into the butter, effectively reducing the amount of actual butter in each serving.
Light butter products can be a good option if you want the butter flavor with fewer calories, though they may not perform the same way in baking due to their altered composition.
Best Low-Calorie Substitutes for Butter
If you're looking to reduce butter calories, here are some effective alternatives:
Plant-based spreads (avocado, olive oil blends)
Many plant-based spreads contain 60-80 calories per tablespoon, offering modest calorie savings while providing different nutritional profiles.
Greek yogurt, unsweetened applesauce (in baking)
These substitutes work particularly well in baking, often reducing calories by 50% or more while adding protein (Greek yogurt) or fiber (applesauce).
Light margarine, nut-based spreads (with less fat)
Light margarines typically contain 45-60 calories per tablespoon. Some nut-based spreads offer similar calorie counts with additional protein and nutrients.
Coconut oil (comparable calories, different fat profile)
While coconut oil has similar calories to butter (about 117 per tablespoon), it offers a different fat composition with medium-chain triglycerides that some people find beneficial.
From my experience, the best substitute depends on how you plan to use it. For spreading on toast, I like avocado-based spreads. For baking, Greek yogurt or applesauce often work well. For high-heat cooking, coconut oil or ghee are my preferred choices.
