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.

Alcohol distillers are not required to label their products with nutrition facts in the same way food manufacturers do, though the federal government has created a voluntary labeling program for beer, wine and liquor companies. In some cases, rum manufacturers may list the calorie contents of their products online.
