Mug of coffee with whole milk (typically 250ml)

From this label you can see that if you add 25ml of milk to your coffee, this will be 17 calories. That is less than 1% of the Reference Intake (RI) for calories.

This is also just over 1% of the Reference Intake for sugars.

If you add a sprinkle of sugar, that’s an extra 16 calories for every teaspoon you stir in.
