How many calories are in a shot of rum?

A standard 1.5-ounce shot of 80-proof rum contains roughly 96 calories. The total calorie content in a shot may vary depending on the brand and proof of the rum as well as whether it contains any added flavorings.

A standard 1.5-ounce shot of most coconut rum brands, such as Malibu, contains only 76.5 calories. This is because coconut rum usually has a lower alcohol proof of roughly 40, compared to traditional white or silver rums that weigh in at 80-proof. Flavored rums, like Bacardi O, often have a lower proof, but the calorie count is driven up by the ingredients used to flavor it. A 1.5-ounce shot of Bacardi O contains 100 calories.
