Matcha powder contains roughly 3 calories per gram. A standard whisked bowl — 2 grams of powder and hot water — is about 6 calories, which rounds to nothing. Every matcha drink with a meaningful calorie count gets there through milk and sweetener, not the tea. That makes matcha calories unusually easy to control once you know what each component adds. Here are the numbers.
Plain matcha: 3 calories per gram
Dry matcha powder runs about 3 to 3.5 kcal per gram — it's ground tea leaf, mostly fiber, protein, and trace carbohydrates. In practice:
- Usucha (thin matcha, 2 g powder + 70 ml water): about 6 calories.
- Single-teaspoon serving (1 g): about 3 calories.
- Koicha (thick matcha, 4 g): about 12 calories.
- Iced matcha with water only: same as hot — about 6 calories.
For anyone tracking in kilojoules or asking about 'matcha kcal': 6 kcal is about 25 kJ. Functionally zero. Plain matcha is one of the lowest-calorie caffeinated drinks that exists, alongside black coffee and plain tea.
Matcha latte calories: it's all in the milk
A matcha latte is 1 to 2 grams of matcha (3 to 6 calories) plus roughly 240 ml (8 oz) of milk. So the latte's calorie count is essentially the milk's calorie count, plus whatever you sweeten it with. Per 240 ml of milk:
- Whole dairy milk: about 150 calories.
- 2% dairy milk: about 120 calories.
- Skim milk: about 80 calories.
- Oat milk: 120 to 160 calories — barista blends sit at the high end because of added oil.
- Soy milk: 80 to 110 calories.
- Unsweetened almond milk: 30 to 40 calories — the lightest realistic latte base.
- Coconut milk beverage (carton, not canned): 45 to 70 calories.
Sweetener adds on top: a tablespoon of honey is about 64 calories, a tablespoon of maple syrup about 52, a typical café pump of vanilla syrup about 20 — and most cafés use three to four pumps in a medium drink.
So a homemade unsweetened matcha latte with almond milk is around 40 calories; with whole milk, around 155; with oat milk and a tablespoon of maple, around 200. Same matcha in all three glasses.
Café and Starbucks matcha latte calories
Starbucks' grande (16 oz) matcha latte with 2% milk is listed at about 240 calories with 32 grams of sugar. The catch most people miss: Starbucks' matcha powder is a pre-sweetened blend — sugar is its first ingredient — so you can't order the drink unsweetened. Asking for fewer scoops lowers both caffeine and sugar together. Independent cafés using real matcha plus syrup give you more control: ask for it unsweetened or half-sweet and the same 16 oz drink can drop to 130 to 180 calories depending on the milk.
Calorie counts for popular matcha drinks
Realistic home-recipe estimates, per serving:
- Plain hot or iced matcha (2 g, water only): about 6 calories.
- Iced matcha latte, unsweetened almond milk: 40 to 50 calories.
- Iced matcha latte, oat milk + 1 tbsp syrup: 180 to 220 calories.
- Hot matcha latte, whole milk, unsweetened: about 155 calories.
- Strawberry matcha (fruit purée + milk + matcha): 180 to 230 calories.
- Matcha lemonade (lemon, simple syrup, water): 80 to 110 calories.
- Matcha frappuccino-style blended drink: 250 to 350 calories with whipped cream.
- Matcha einspanner (sweetened matcha + cream cap): 220 to 280 calories.
Does matcha burn calories?
Honest answer: a little, and less than the supplement marketing implies. Green tea catechins (especially EGCG) combined with caffeine have been shown in controlled studies to nudge energy expenditure up — typically by around 3 to 4 percent for a few hours, which works out to tens of calories, not hundreds. Matcha is a reasonable swap into a diet because it replaces higher-calorie drinks and delivers steady energy, not because it meaningfully burns fat on its own. Any article promising otherwise is selling something.
Frequently asked
How many calories are in matcha powder?
About 3 to 3.5 calories per gram. A standard 2-gram serving is roughly 6 calories; a heaping teaspoon (about 2 g) the same. The powder is ground whole tea leaf — mostly fiber and protein with trace carbs.
How many calories in a matcha latte?
Anywhere from 40 to 240+, decided almost entirely by the milk and sweetener. Unsweetened almond milk: about 40. Whole milk, no sugar: about 155. Oat milk with syrup: about 200. A Starbucks grande with its pre-sweetened powder: about 240.
How many calories in a matcha green tea latte from Starbucks?
About 240 calories for a grande (16 oz) with 2% milk, including 32 g of sugar from the pre-sweetened matcha blend. A tall is about 190; switching to almond milk drops a grande to about 160.
Is matcha good for weight loss?
It can help as a swap, not as a fat burner. Plain matcha is a 6-calorie drink with enough caffeine and L-theanine to be satisfying, so replacing a 250-calorie sweetened latte habit with it removes real calories. The metabolic boost from catechins is real but small — on the order of tens of calories a day.
Does matcha with water have calories?
About 6 calories per 2-gram bowl — close enough to zero that most tracking apps log it as a free drink. Unlike steeped tea, you do consume the whole leaf, which is where those few calories come from.
