A green tea matcha latte can range from 70 to over 400 calories depending on ingredients like milk, sweeteners, and serving size. Choosing unsweetened plant-based milk and skipping added sugar can keep your drink low-cal while still delivering matcha’s powerful antioxidants and calm energy boost.
If you’ve ever stood in line at a trendy café, eyeing the menu board with a mix of curiosity and confusion, you’re not alone. Matcha lattes have taken the wellness world by storm—creamy, vibrant green, and promising a smooth caffeine lift without the jitters. But as delicious as they look, many people wonder: How many calories in green tea matcha latte? The answer isn’t one-size-fits-all. It depends on where you get it, how it’s made, and what goes into your cup.
Unlike plain green tea, which is virtually calorie-free, a matcha latte combines finely ground green tea powder with milk—and often sweeteners—creating a drink that’s more like a dessert than a simple brew. While matcha itself is packed with health benefits, including antioxidants and amino acids that support mental clarity, the additions can quickly turn this healthy habit into a calorie bomb. Whether you’re watching your weight, managing blood sugar, or just curious about what you’re sipping, understanding the calorie breakdown is essential.
Key Takeaways
- Calorie count varies widely: A homemade matcha latte with unsweetened almond milk may have only 70–100 calories, while a sweetened café version can exceed 400.
- Milk choice matters: Whole milk and oat milk add more calories than almond, coconut, or skim milk—opt for low-cal options to reduce intake.
- Sweeteners are the hidden calorie culprit: Syrups, sugar, and flavored powders can double the calorie count—use natural alternatives like stevia or monk fruit.
- Matcha itself is low in calories: Pure matcha powder contains only about 10–15 calories per teaspoon, so the bulk of calories come from added ingredients.
- Size and preparation impact nutrition: A large 16-oz (475ml) latte typically has more calories than an 8-oz serving—portion control is key.
- Health benefits remain intact: Even with added milk, matcha lattes retain antioxidants, L-theanine for focus, and metabolism-supporting compounds.
- DIY is best for control: Making your own matcha latte at home lets you customize ingredients and keep calories in check.

What Is a Green Tea Matcha Latte?
A green tea matcha latte is a creamy, frothy beverage made by whisking high-quality matcha powder into hot water and then mixing it with steamed milk. Unlike traditional green tea, where leaves are steeped and discarded, matcha involves consuming the entire ground tea leaf, which means you get a more concentrated dose of nutrients, caffeine, and flavor.
The drink originated in Japan, where matcha has been used in tea ceremonies for centuries. Today, it’s a global favorite, served hot or iced, sweetened or unsweetened, and often customized with flavors like vanilla, honey, or even chocolate. But while the base ingredient—matcha—is naturally low in calories and rich in health-promoting compounds, the final calorie count of your latte depends heavily on how it’s prepared.
Key Ingredients That Affect Calories
To understand how many calories in green tea matcha latte, let’s break down the main components:
– Matcha powder: About 10–15 calories per teaspoon (2 grams). This is the star of the show and contributes minimal calories.
– Milk: This is where calories add up. Whole milk (about 150 calories per cup), oat milk (120–130 calories per cup), and coconut milk (45–50 calories per cup, but often used in smaller amounts) all vary significantly.
– Sweeteners: Sugar, honey, agave, or flavored syrups can add 50–150 calories or more per serving.
– Flavorings: Vanilla extract, cinnamon, or cocoa powder usually add negligible calories, but pre-made syrups can be loaded with sugar.
Because matcha is so potent, you only need a small amount—typically half to one teaspoon—per drink. That means the milk and sweeteners are the real calorie drivers.
Calorie Breakdown: Homemade vs. Café Matcha Lattes
The biggest difference in calorie count comes from where and how your matcha latte is made. Let’s compare a few common scenarios.
Homemade Matcha Latte (Low-Cal Version)
If you make your matcha latte at home using unsweetened almond milk and no added sugar, you’re looking at a very lean drink. Here’s a typical recipe:
– 1 tsp matcha powder (12 calories)
– 1 cup unsweetened almond milk (30–40 calories)
– Optional: a dash of cinnamon or vanilla extract (0 calories)
Total: ~50–60 calories
This version gives you all the benefits of matcha—antioxidants, L-theanine for calm focus, and a gentle caffeine boost—without the extra sugar or fat. It’s perfect for weight management, fasting windows (if you’re not strict about zero calories), or anyone who wants a clean energy drink.
Café-Style Matcha Latte (Higher-Cal Version)
Now, let’s look at what you might get at a popular coffee shop. A standard 16-oz (475ml) matcha latte often includes:
– 1–2 tsp matcha powder (12–24 calories)
– 1.5 cups whole milk (225 calories)
– 2–3 pumps of vanilla or matcha syrup (100–150 calories)
Total: 337–400+ calories
That’s more than a can of soda and nearly as much as a small meal! And if you add whipped cream or a flavored drizzle, the count climbs even higher. While delicious, these versions can sabotage your daily calorie goals if consumed regularly.
Iced Matcha Latte: Cold Doesn’t Mean Low-Cal
Don’t be fooled by the refreshing chill of an iced matcha latte. Many iced versions use the same high-calorie ingredients as their hot counterparts. In fact, some iced drinks include even more syrup to compensate for dilution from melting ice. Always ask for “unsweetened” or “lightly sweetened” when ordering, or better yet, make your own at home.
How Milk Choice Affects Calories
One of the easiest ways to cut calories in your matcha latte is by choosing the right milk. Here’s a quick comparison of common milk options per 1 cup (240ml):
- Unsweetened almond milk: 30–40 calories, 2.5g fat, 1g protein
- Unsweetened oat milk: 80–120 calories, 1.5g fat, 3g protein (higher in carbs)
- Skim milk: 80–90 calories, 0g fat, 8g protein
- Whole milk: 150 calories, 8g fat, 8g protein
- Coconut milk (canned, light): 45–70 calories, 4–7g fat, 0g protein (use sparingly)
For the lowest calorie option, unsweetened almond or skim milk are your best bets. Oat milk is creamier and tastes great, but it’s higher in calories and carbohydrates, so it may not suit low-carb or calorie-restricted diets. Coconut milk adds a tropical twist but is high in saturated fat—best used in moderation.
Plant-Based vs. Dairy: Which Is Better?
Both plant-based and dairy milks have pros and cons. Dairy milk offers more protein and calcium, which can be beneficial for bone health and satiety. Plant-based milks are often lower in calories and suitable for vegans or those with lactose intolerance. The key is choosing unsweetened versions to avoid hidden sugars.
Sweeteners: The Hidden Calorie Culprit
Even if you choose a low-calorie milk, sweeteners can undo all your efforts. Many café matcha lattes come pre-sweetened with flavored syrups that pack a sugary punch. A single pump of vanilla syrup can add 20–30 calories and 5–7 grams of sugar.
Healthier Sweetener Alternatives
If you like your latte a little sweet, consider these lower-calorie options:
– Stevia: Zero calories, naturally derived, doesn’t spike blood sugar.
– Monk fruit extract: Zero calories, sweet taste, great for keto diets.
– Honey or maple syrup (in moderation): While natural, these still add calories—use sparingly (1 tsp = ~20 calories).
– Cinnamon or nutmeg: Adds warmth and sweetness without calories.
Pro tip: Gradually reduce the amount of sweetener you use. Your taste buds will adapt, and you’ll enjoy the natural earthy flavor of matcha more.
Does Matcha Latte Fit Into a Healthy Diet?
Absolutely—when made wisely. A well-prepared green tea matcha latte can be part of a balanced diet. Matcha is rich in catechins, especially EGCG, a powerful antioxidant linked to reduced inflammation, improved brain function, and even fat burning. It also contains L-theanine, an amino acid that promotes relaxation without drowsiness, creating a calm, focused energy.
Matcha vs. Coffee: A Calmer Energy Boost
Unlike coffee, which can cause jitters and crashes, matcha provides a smoother, more sustained release of caffeine. This is due to the combination of caffeine and L-theanine, which work together to enhance alertness while reducing anxiety. For this reason, many people prefer matcha for mental clarity and productivity.

Can You Drink Matcha Latte While Fasting?
This depends on your fasting goals. If you’re doing intermittent fasting for weight loss, even 50–60 calories might break your fast, depending on your protocol. However, some people tolerate small amounts of matcha with unsweetened almond milk during fasting windows, especially if they’re focused on autophagy or metabolic health.

Tips for Making a Low-Calorie Matcha Latte at Home
Making your own matcha latte is simple, cost-effective, and gives you full control over ingredients. Here’s how to do it right:
1. Use high-quality matcha: Look for ceremonial-grade matcha for the best flavor and color. Culinary-grade is fine for lattes but may taste more bitter.
2. Sift the powder: This prevents clumps and ensures a smooth texture.
3. Whisk with hot (not boiling) water: About 175°F (80°C) is ideal. Boiling water can make matcha taste bitter.
4. Choose unsweetened milk: Almond, oat, or skim milk work well. Steam or heat gently.
5. Add flavor naturally: A pinch of cinnamon, vanilla extract, or a drop of stevia can enhance taste without calories.
6. Serve immediately: Matcha lattes taste best fresh.
