How Many Calories in Olive Oil?
Olive oil is the most energy-dense thing in most kitchens, so the amount you pour matters far more than the bottle you buy. The calculator below turns any pour into real numbers.

Pick a measure or drag the slider to see what a pour really costs — in calories, kilojoules and grams of fat.
Heads-up: a tablespoon isn’t one fixed size. A US/metric tablespoon is 15 ml (~120 kcal), but an Australian tablespoon is 20 ml (~160 kcal). Values are approximate.

Pure fat, pure energy
Olive oil is essentially 100% fat, so it carries no carbohydrate, sugar or protein — just energy. At roughly 8 calories per millilitre, a teaspoon lands near 40 calories and a tablespoon near 120. That density is the same for every cooking oil and for butter, because all pure fat releases about 9 calories per gram.
The catch is the untracked “glug.” Free-pouring to coat a pan can quietly add 200–300 calories to a meal you thought was light. A teaspoon or tablespoon measure is the simplest way to keep that honest — and remember an Australian tablespoon (20 ml) is a third bigger than the US one (15 ml).
“Light” olive oil is not lighter
This trips a lot of people up: extra virgin, virgin and “light” olive oils all have the same calories. “Light” describes a milder flavour, paler colour and higher smoke point produced by extra refining — not a reduction in fat or energy. If anything, refining strips away some of the antioxidants that make extra virgin worth buying.
Why nutritionists still love it
Calorie-dense does not mean unhealthy. Around 73% of olive oil’s fat is monounsaturated oleic acid, which is linked to lower “bad” LDL cholesterol and reduced inflammation. Extra virgin oil, cold-pressed without solvents, also keeps antioxidants such as oleocanthal — a compound with anti-inflammatory effects often compared to ibuprofen — plus vitamins E and K.
It is the centrepiece of the Mediterranean diet for good reason. The goal isn’t to fear it, but to use it deliberately: enough to get the flavour and the benefits, measured rather than poured by eye.
