Calories in Popular Coffee Drinks: What to Know

If you’re watching your calorie intake but still want your daily coffee fix, it pays to know exactly how many calories are hiding in your favorite drinks. From a plain shot of espresso to a sugary mocha, coffee beverages can vary dramatically in calorie content—some have almost none, while others pack in over 200 calories per serving. Here’s what you need to know before you order.

The lowest-calorie coffee option is plain black coffee or espresso: a typical 100g cup of black coffee has just 2.55 kcal, and a standard espresso (about 30ml) has around 117 kcal without milk or sugar. In contrast, a standard latte can contain up to 220 kcal, while a mocha may reach 235 kcal due to added chocolate. Cappuccinos fall in the middle with about 75 kcal, depending on milk type and portion.

1. Espresso & Moka Pot Coffee

Espresso—commonly made using a moka pot in Italy—is a concentrated coffee brewed under steam pressure. The hot steam forces water through finely-ground coffee, extracting intense flavor and leaving a thin layer of crema on top. This method delivers a bold, bitter cup with rich aroma thanks to the coffee oils that rise to the surface.

• Flavor intensity: High
• Calories (per shot, ~30ml): ~117 kcal
• Health & calorie rating: Low-calorie if taken black
• Taste score: ★★★★☆
• Health score: ★★★☆☆
• Weight gain risk (no sugar/milk): ★☆☆☆☆

Moka pots, invented in Italy, use steam pressure to push water through coffee grounds. The resulting brew shares characteristics with espresso—strong, rich, and topped with a small amount of crema. Though not a true espresso, it’s similar in concentration and calorie count when consumed without additions.

2. Black Coffee

Black coffee is simply brewed coffee with nothing added. It’s the lightest option by far. A 100g serving contains just 2.55 kcal. Even better for weight control, hot black coffee may slightly boost metabolism, and lighter roasts tend to have slightly more caffeine, aiding fat burning. Darker roasts, while richer in taste, usually contain less caffeine.

• Calories (per 100g): ~2.55 kcal
• Health & calorie rating: Very low
• Taste score: ★★★☆☆
• Health score: ★★★☆☆
• Weight gain risk: ★☆☆☆☆

3. Milk-Based Coffees

Latte

A latte consists of a single or double shot of espresso mixed with plenty of steamed milk and a small layer of milk foam. The drink is mostly milk—typically around 75% or more—which adds calories primarily from fat and carbohydrates. A standard latte can easily reach around 220 kcal, depending on the size and milk type (whole, skim, or plant-based).

• Calories: ~220 kcal
• Flavor profile: Creamy, mild coffee flavor
• Taste score: ★★★★★
• Health score: ★★★★☆
• Weight gain risk: ★★★☆☆

Cappuccino

A cappuccino is made with a shot of espresso and equal parts steamed milk and milk foam. The foam lightens the drink, but it still contains a significant amount of milk. Served traditionally in a 150–180ml cup, it typically contains around 75 kcal, though this can vary with milk choice.

• Calories: ~75 kcal
• Flavor profile: Balanced coffee and milk
• Taste score: ★★★★★
• Health score: ★★★★☆
• Weight gain risk: ★★★☆☆

Mocha

A mocha combines espresso, steamed milk, and chocolate syrup or powder—essentially a café-style hot chocolate with coffee. The added chocolate boosts both sweetness and calories, bringing the total to around 235 kcal for a standard version. It’s the most calorie-dense drink listed here and should be approached cautiously if you're limiting sugar or calories.

• Calories: ~235 kcal
• Flavor profile: Sweet, chocolatey, coffee-forward
• Taste score: ★★★★★
• Health score: ★★☆☆☆
• Weight gain risk: ★★★★★

4. Instant Coffee

Instant coffee varies widely in calorie content based on brand and whether it includes added ingredients. Most plain instant coffees are very low in calories, but flavored or packaged versions (especially those targeting cafes or ready-to-drink markets) can contain significantly more.

Frequently Asked Questions

Which coffee has the fewest calories?

Black coffee or espresso has the fewest calories, with as little as 2.55 kcal per 100g for black coffee and around 117 kcal for a standard 30ml espresso shot (without milk or sugar). Both are very low in calories if consumed plain.

How many calories are in a latte?

A standard latte contains approximately 220 calories, mainly from the milk. The exact count can vary based on portion size and whether whole, skim, or plant milk is used.

Why do some coffees have so many calories?

Coffees with added milk, sugar, syrups, or chocolate—like lattes, mochas, and flavored drinks—have higher calories due to the carbohydrates and fats in those ingredients. A mocha can reach 235 kcal largely because of the chocolate content.

Is cappuccino a low-calorie coffee option?

Yes, a cappuccino is relatively low in calories, with around 75 kcal per serving. It contains less milk than a latte, as it is made with equal parts espresso, steamed milk, and foam.

Are instant coffees high in calories?

Most plain instant coffees are very low in calories (around 2 kcal per serving), but flavored or pre-packaged instant coffees, especially those with added ingredients, can range from 42 kcal up to 139 kcal per serving.

Does espresso or black coffee help with weight loss?

Yes, black coffee is very low in calories and may slightly boost metabolism, especially when consumed hot. Lighter roasts often have slightly more caffeine, which can support fat burning. However, adding sugar or milk increases calories significantly.
