Tea is a commonplace drink consumed by two-thirds of the world’s population.
It’s made from Camellia sinensis, also known as the tea plant, cultivated for thousands of years for its taste and medicinal properties.
Although plainly brewed tea contains virtually no calories, numerous ready-to-drink, and flavored tea shop choices are loaded with added sugars and fats.
This article examines how many calories are in various types of tea and provides tips on reducing your tea’s calorie count.
Plain tea is calorie-free
Tea is a minimally processed drink generally prepared by pouring hot water over the leaves, buds, or stems of the Camellia sinensis plant, resulting in an aromatic infusion.
Since those parts of the plant contain only trace amounts of carbs, tea is virtually a calorie-free beverage.
For example, an 8-ounce cup (240 ml) of freshly brewed black tea offers barely 2 calories, which is considered negligible. The same goes for most infusions.
As such, plain tea makes an excellent substitute for sugar-sweetened beverages.
Its caffeine and polyphenol antioxidants also provide numerous health benefits, including aiding weight loss, improving heart health, and reducing your risk of chronic disease.
Summary: Plain tea is minimally processed and provides roughly 2 calories per cup (240 ml), which makes it nearly calorie-free.
Calories in different types of tea
Although tea has almost no calories, popularly added ingredients like milk and sugar may considerably increase its calorie count.
Here are some widely consumed teas and their estimated number of calories.
Green, black, oolong, and white teas
These four teas come from the Camellia sinensis plant, with their main being the extent to which their leaves are fermented.
Green tea is non-fermented, while oolong and black teas are partly and fully fermented. White tea is considered a variety of green tea, as it’s minimally fermented.
When prepared only with hot water, their calorie count is as low as 2–3 calories per 8-ounce (240-ml) cup.
Yet, as sugar and honey are the most common ways to sweeten these teas, sprinkling in just 1 teaspoon (4 grams) of sugar adds 16 calories to your drink, while 1 tablespoon (21 grams) of honey adds 64 calories.
Herbal teas are infusions made by brewing herbs, dried fruit, leaves, flowers, or buds from plants other than Camellia sinensis.
Some popular herbal teas, which are renowned for their therapeutic properties, include chamomile, peppermint, lavender, rooibos, peppermint, lavender, rooibos, and hibiscus.
Like traditional teas, their calorie contents are considered insignificant. Some, such as hibiscus tea, even boast no calories at all.
Still, if you add sweeteners or dairy, the number of calories increases.
Milk tea is prepared with a 1:1 ratio of tea to milk — usually whole milk for extra creaminess. It’s typically sweetened with sugar or honey; some recipes include spices like salt, cinnamon, and cardamom.
While black tea is most commonly used, you can use any type of tea to prepare milk tea.
If you use 4 ounces (120 ml) of whole milk for an 8-ounce (240-ml) beverage, it will pack 75 calories from the milk alone. However, switching to skim milk can reduce the count to 42 calories.
Remember to consider your choice of sweetener, as some sugar substitutes can be used to sweeten without adding extra calories.

A tea latte is a variation of milk tea prepared at a 1:3 ratio of tea to milk. Therefore, its higher milk content packs more calories.
It has become very popular in tea shops and coffee chains, which tend to add flavored syrups as well. These additives further increase the calorie content of your drink.
For example, Starbucks’ 12-ounce (355-ml) London Fog Tea Latte combines Earl Grey tea with reduced-fat milk and vanilla syrup for 140 calories.
Bubble tea, also known as boba or pearl milk tea, is a Taiwanese drink with small, chewy tapioca balls. It’s usually made from black tea, sweetened condensed milk, syrup or honey, and tapioca pearls.
Sweetened condensed milk is full-fat cow’s milk that has been partly evaporated and sweetened with sugar, resulting in a thick, high-calorie dairy product. Just 1 ounce (30 ml) packs 122 calories.
As boba tea has gained popularity, some shops have also started adding jelly, egg pudding, and fruit juice.
Its calorie content varies greatly, as you can add ingredients to your liking. All the same, it’s estimated that 16 ounces (480 ml) of bubble tea packs 200–450 calories.
Iced and sweet teas
Iced and sweet teas are cold versions of black tea, usually flavored with lemon, peach, or mint. Their main difference is their added sugar content.
While they’re both American staples, sweet tea is more common in Southern states, while unsweetened iced tea is typically served in the North.
As its name suggests, sweet tea is sweetened with sugar — and its calorie content depends on the amount added. In contrast, unsweetened iced tea is consumed without it and therefore doesn’t contain calories.
Remember that every teaspoon (4 grams) of sugar adds 16 calories to your tea.

Nonetheless, some popular brands don’t differentiate between iced and sweet tea and may sell their iced teas sweetened. In those cases, the total number of calories significantly increases. Therefore, it’s essential to read the label to check for added sugar.
For example, Snapple’s 16-ounce (475-ml) Lemon Tea packs 150 calories, and the same serving size of AriZona Iced Tea with Lemon Flavor boasts 140 calories.
Thai tea is another version of milk tea popular in Southeast Asia.
Served either hot or cold, it mixes black tea, sugar, and sweetened condensed milk and is topped with coconut or whole milk.
These heavy ingredients give a single 8-ounce (240-ml) serving 160 calories.
Chai tea is also called masala chai, meaning “spiced tea.”
This flavorful milky beverage is made from black tea, heavy cream, sugar, and a mix of spices — usually cardamom, ginger, cinnamon, pepper, and cloves.
Heavy cream is exceptionally high in fat. It boasts 100 calories per ounce (30 ml).
Chai tea may also be served hot or cold. Unlike regular milk tea brewed in water first, chai is brewed directly in milk.
As chai recipes vary, so does the drink’s calorie content.
For reference, Starbucks’ 16-ounce (480-ml) Chai Tea Latte prepared with reduced-fat milk offers 240 calories.
Summary: The calorie content of tea and tea-based drinks ranges from 0–450, depending on the ingredients used. The addition of sugar, as well as various dairy products, may raise the number of calories drastically.
How to reduce your tea’s calorie count
There are multiple ways to reduce the calorie content of your favorite tea. Here are a few tips:
- Avoid sugary ingredients. These include sugar, honey, syrups, and sweetened condensed milk. If you’re still craving the extra sweetness, try a sugar substitute or a sugar-free alternative.
- Opt for low-fat or skim milk. You’ll consume fewer calories by switching from whole milk or heavy cream to low-fat or skim milk.
- Try milk substitutes. Unsweetened non-dairy milk, such as almond or soy milk, contain fewer calories than whole milk or coconut milk.
- Reduce your intake of bottled teas. Sweetened, bottled, ready-to-drink teas tend to load you with calories due to their high sugar content. Try to stick to freshly brewed teas or choose unsweetened versions of ready-to-drink teas without any extra ingredients.
As tea is easy to make at home, you can exercise control over what added ingredients you use — if any.
Summary: You can quickly turn a high-calorie tea into a low-calorie or even calorie-free one by swapping out a few ingredients. You’ll have more control if you make your tea at home or choose lower fat, lower sugar options when purchasing tea in a shop or off the shelf.
Plain teas, such as green, black, oolong, and white, as well as herbal teas, are virtually calorie-free.
However, other popular varieties may include milk, sugar, syrup, and other high-calorie ingredients. Just 16 ounces (480 ml) of bubble tea can pack up to 450 calories.
Still, you can lower your tea’s calorie content by swapping out some ingredients or simply drinking it plain.
