Costa Americano (UK Price & Calories 2026)
When I first tried the Costa Americano, the thing that stood out immediately was how clean and strong the coffee tasted. It doesn’t have the creaminess of a latte, but that’s exactly the point. You mostly taste the espresso itself, slightly diluted with hot water. If you drink it black, it’s surprisingly light in calories but still feels like a proper coffee.
If you’re used to milk-based drinks like lattes or cappuccinos, the Americano will usually taste stronger and more direct.

Costa Americano sizes and price breakdown
Costa keeps the Americano pricing fairly simple. The small cup is usually around £3.45 for about 260 ml, the medium sits near £3.85 with roughly 340 ml, and the large goes up to around £4.25 for about 450 ml. Most people pick the medium size because it offers a good balance between coffee strength and volume.
How many calories are in a Costa Americano?
One reason people choose an Americano is how low the calories are. Even the largest 450 ml cup only contains around 23 kcal, which is extremely small compared to most milk-based coffee drinks. Sugar, fat, and salt levels are also very low, especially when the drink is ordered black without milk or syrups.
| Size | Portion (ml) | Energy (kcal) | Energy (kJ) | Sugar (g) | Fat (g) | Saturates (g) | Carbs (g) | Protein (g) | Salt (g) |
| Small | 260 | 12 | 48.7 | 0.1 | 0.1 | 0.1 | 1.9 | 0.8 | 0.06 |
| Medium | 340 | 18 | 74.2 | 0.1 | 0.2 | 0.1 | 3 | 1.2 | 0.08 |
| Large | 450 | 23 | 97.4 | 0.1 | 0.2 | 0.1 | 3.7 | 1.6 | 0.12 |
Extras and syrups you can add to an Americano
Although the Americano itself is very low in calories, Costa allows you to customise it with extras and syrups. For example, an extra espresso shot usually costs about +£0.80, while toppings like marshmallows or whipped cream can add around +£0.50 to +£0.60. Flavoured syrups such as caramel, vanilla, or hazelnut are also available, including some sugar-free options. Just keep in mind that these additions increase both the price and the calories of the drink.
Simple tips when ordering a Costa Americano
- Choose the small size if you want the lowest calories and the cheapest option.
- The medium size is usually the most popular because it balances strength and volume well.
- Drinking it black keeps the calories extremely low compared to milk-based drinks.
- If you prefer stronger coffee, adding an extra espresso shot can give it a stronger kick.
