Olive oil basics
Olive Oil Calories: What a Real Serving Actually Costs You
Olive oil is pure fat, so its calorie count is fixed and grade does not change it. Here is the number per tablespoon, teaspoon and 100ml, and why extra virgin costs the same as any other bottle.
The short answer
One tablespoon of olive oil (about 13.5g) is roughly 119 kcal, and one teaspoon is about 40 kcal. That figure is the same for extra virgin, pure or light olive oil, because all three are close to 100% fat. The grade changes flavour and processing, never the calorie count.
Olive oil is calorie-dense because it is almost entirely fat, and fat carries more than double the calories of protein or carbohydrate, gram for gram. That single fact explains every number below.
The count does not move with the grade on the label. Extra virgin, pure and light olive oil are all close to 100% fat, so a tablespoon of any of them costs about the same.
How many calories are in a tablespoon?
A level tablespoon of olive oil is about 13.5g and comes to roughly 119 kcal, almost all of it fat. A teaspoon, at about 4.5g, is close to 40 kcal. These are standard figures for any pure vegetable oil, not something specific to one brand or bottle.
| Amount | Weight | Calories | Fat |
|---|---|---|---|
| 1 teaspoon | 4.5g | ~40 kcal | 4.5g |
| 1 tablespoon | 13.5g | ~119 kcal | 13.5g |
| 50ml | ~46g | ~405 kcal | 46g |
| 100ml | ~91g | ~805 kcal | 91g |
Does extra virgin have more calories than pure or light?
No. Extra virgin, pure and light olive oil are all essentially 100% fat by weight, so the calorie count per tablespoon is the same across all three. What changes between grades is how the oil was extracted and refined, which is a flavour and processing story, not a calorie one.
The word "light" on a bottle refers to colour and taste, not to calories. Extra light olive oil vs extra virgin olive oil covers what that grade actually changes.
How does it compare with other cooking oils?
Almost every liquid cooking oil sits in the same range, because they are all close to pure fat: canola, sunflower, corn and coconut oil all land around 120 kcal per tablespoon, give or take a few. Butter is lower per tablespoon because it carries some water and milk solids rather than being pure fat.
Choosing an oil for the calorie count alone rarely changes much. The bigger swing in a dish is usually how much oil is used, not which bottle it came from.
Does frying add more calories than a salad drizzle?
Yes, but the reason is portion, not the oil itself. A salad drizzle is usually a measured tablespoon or two. Shallow-frying can pull in far more, because food absorbs oil as it cooks, particularly anything breaded or porous like aubergine.
- A teaspoon drizzle on a finished dish adds about 40 kcal.
- A tablespoon in a dressing adds about 119 kcal to the whole bowl, not per portion.
- Shallow-frying can add well over 100 kcal per portion depending on how absorbent the food is.
- Wiping a pan with a paper towel dipped in oil for a non-stick coat adds only a small fraction of a tablespoon.
Is a higher calorie count a reason to avoid it?
Not on its own. Calorie density is a property of fat in general, not a mark against olive oil specifically, and the same tablespoon applies to any oil in the kitchen. What differs between oils is flavour, smoke point and what has been done to them during processing.
Olive oil is a food, not a diet plan. Anyone managing calorie intake for a medical reason should get portion guidance from a doctor or registered dietitian rather than a blog post.
How do you measure a serving accurately?
A free-pour from the bottle is usually more than a tablespoon, because the spout does not measure. A proper tablespoon or teaspoon measure, or a bottle with a built-in pourer, keeps a dressing or a drizzle at the amount actually intended.
For cooking rather than dressing, a light coating of a pan with a tablespoon is normally enough for two to three servings, which brings the added calories per portion down to well under 50 kcal.
What should you take from the number?
Use the tablespoon and teaspoon figures above to judge a real serving rather than guessing, and do not pick a lower grade expecting fewer calories, because the count will not move. If calories matter to your cooking, the lever that actually works is how much oil goes in the pan, not which bottle it comes from.
