Figuring out how many calories are in vodka all depends on the amount you are drinking. If you are drinking in a 1.5 ounce shot glass and the vodka is 80 proof then that has about 60 calories per shot. If you are drinking in a 1.5 ounce glass and the vodka is 100 proof then that will have about 70 calories. These numbers can vary depending on the type of vodka and if it is flavored. Some of the flavored vodka has more sugar which means more calories.
