How many calories are in a shot of rum?
A 1.5 fl oz shot of rum is 42 g and 97 calories. Straight rum runs 231 calories per 100 g, and every one of those calories comes from alcohol: zero carbs, zero sugar, zero fat, zero protein. The number on your glass depends on two things only, how much you pour and what you pour it into.
You'd need to walk about 19 minutes to burn the 97 calories in one shot (42 g).

Rum quick facts
The numbers below come from the FoodData Central record FNDDS 2710703, "Rum", which is standard 80 proof rum as it is poured. It is the only entry for plain rum that carries American household measures, shot, jigger and drink, so it matches what a person is actually holding. The older SR Legacy record 174817 lists the same 231 calories per 100 g for 80 proof rum but gives no such pours, so it is a cross-check rather than the source.
The main column is a 1.5 fl oz shot, the pour a bartender measures with a jigger and the one most home recipes assume.
| Nutrient | Per 100 g | Per 1 shot (42 g) | % Daily Value |
|---|---|---|---|
| Calories | 231 | 97 | — |
| Total fat | 0 g | 0 g | 0% |
| Saturated fat | 0 g | 0 g | 0% |
| Carbohydrate | 0 g | 0 g | 0% |
| Dietary fiber | 0 g | 0 g | 0% |
| Total sugars | 0 g | 0 g | — |
| Protein | 0 g | 0 g | 0% |

Verified nutrition data
Numbers on this page come from USDA FoodData Central, the U.S. Department of Agriculture’s food composition database, and from manufacturer labels where a branded product is named. Last verified September 2026. How we verify our data →
Two rows that appear on a packaged food label are missing here on purpose. USDA does not publish added sugars or trans fat for this record, so nothing is guessed in their place, and for a distilled spirit both would read zero anyway. Cholesterol is 0 mg. Potassium is 2 mg per 100 g, which works out to 1 mg in a shot, a rounding error against the 4,700 mg Daily Value.
That leaves a nutrition table that is almost entirely zeros with one line doing all the work. Ethanol carries about 7 calories per gram, and it is the only thing in the glass besides water. The FDA Daily Value reference has no entry for alcohol, which is why the %DV column stays flat at 0% no matter how large the pour gets.
US pours from one ounce to a double
| Serving | Weight | Calories |
|---|---|---|
| 1 fl oz, no ice | 28 g | 65 kcal |
| 1 shot or jigger, 1.5 fl oz | 42 g | 97 kcal |
| 1 drink as poured at home | 63 g | 146 kcal |
| 2 shots, a double | 84 g | 194 kcal |
| Per 100 g | 100 g | 231 kcal |
The first three lines are USDA household measures attached to the record itself. The double is our own arithmetic from the USDA 100 g figure, not a USDA serving: two 42 g shots come to 84 g and 194 calories. An ounce by weight, 28.4 g, is our own scaling from the same USDA 100 g figure and lands on the same 65 calories as the fluid ounce, because rum is slightly lighter than water and the two measures nearly cancel out.
Notice the gap between the shot and the drink. A jigger is 42 g, but the "1 drink" measure USDA records for rum is 63 g, half again as much, and that is closer to what a free pour looks like when nobody is measuring. If you log shots and pour drinks, you are 49 calories short every glass.
What the mixer adds
| Version | Per 100 g | Typical glass | Calories |
|---|---|---|---|
| Rum and cola | 89 kcal | 1 drink (225 g) | 200 kcal |
| Rum and diet cola | 60 kcal | 1 drink (225 g) | 135 kcal |
| Hot buttered rum | 160 kcal | 1 drink (90 g) | 144 kcal |
Per 100 g a rum and cola looks light at 89 calories, less than half of straight rum. That is dilution, not virtue. The glass is 225 g instead of 42 g, so the finished drink lands at 200 calories, roughly double a shot.
Swapping to diet cola takes the same glass to 135. The 65-calorie difference is the sugar in the soda and nothing else, and it is the single cheapest edit on this page. Rum and cola also carries 7.8 g of carbohydrate per 100 g, about 17.6 g in the glass, nearly all of it sugar; the rum contributed none of it.
Hot buttered rum is the outlier. At 160 calories per 100 g it is the densest drink in this table, and a small 90 g mug is 144 calories with 4.47 g of fat and 2.52 g of saturated fat per 100 g. That saturated fat comes from the butter, not the spirit. Two mugs put you near a quarter of the 20 g saturated fat Daily Value, from a drink most people file mentally under "just a rum."
Proof moves the number more than the brand
Proof is alcohol by volume doubled, and it is the only spec on the bottle that changes the calorie count. USDA publishes distilled spirits at four strengths, and rum sits inside every one of them.
| Strength | Per 100 g | 1 shot (42 g) |
|---|---|---|
| 80 proof, 40% ABV | 231 kcal | 97 kcal |
| 86 proof, 43% ABV | 250 kcal | 105 kcal |
| 90 proof, 45% ABV | 263 kcal | 110 kcal |
| 100 proof, 50% ABV | 295 kcal | 124 kcal |
An overproof bottle costs you 27 calories on the same 1.5 fl oz pour, a 28% jump for a shot that looks identical in the glass. Navy strength and cask strength rums sit at or above that 100 proof line, so check the label before assuming the standard number.
Spiced rum is the common question here, and the honest answer is that USDA publishes no separate record for it, so this page will not put a number on it. Most spiced bottles are sold at 70 to 80 proof, which puts them at or slightly below the 231 calories per 100 g of standard rum, but any sugar or vanilla added after distillation would not show up in a USDA distilled spirits record at all.
Zero carbs and what the bottle does not tell you
Spirits bottles do not carry a Nutrition Facts panel. Distilled alcohol is regulated by the Alcohol and Tobacco Tax and Trade Bureau rather than by FDA food labeling rules, which is why USDA's branded food database contains no rum bottles at all. Every American branded match for "rum" is a rum-flavored food instead: rum cake, rum buns, rum raisin chocolate, spiced rum barbecue sauce. Those run between 129 and 672 calories per 100 g and have nothing to do with what is in your glass.
So the zeros are real. Plain rum has 0 g of carbohydrate and 0 g of sugar, which is why it clears a low-carb or keto carb budget on the spirit alone. It has 0 g of protein too, meaning none of those 97 calories does anything for fullness. That is the trade: 97 calories that leave the appetite exactly where they found it.
For context on how many of these add up in a week, the CDC's guidance on moderate alcohol use defines a standard drink as 1.5 fl oz of 80 proof spirits, the same 42 g shot in the table above, and the Dietary Guidelines for Americans treat alcohol calories as calories that displace food rather than add nutrients. If you are tracking, log the pour before the mixer; it is the part people forget.
How does rum compare?
| Spirit | Per 100 g | US serving | Calories |
|---|---|---|---|
| Rum | 231 kcal | 1 fl oz, no ice (28 g) | 65 kcal |
| Vodka | 231 kcal | 1 fl oz, no ice (28 g) | 65 kcal |
| Whiskey | 231 kcal | 1 fl oz, no ice (28 g) | 65 kcal |
| Tequila | 231 kcal | 1 fl oz, no ice (28 g) | 65 kcal |
Our take: at 80 proof all four spirits are the same number, 231 calories per 100 g, right down to the decimal. Anyone telling you vodka is the diet choice over rum is repeating a myth the data does not support. Switching spirits saves nothing; switching the mixer saves 65 calories a glass, and pouring a 42 g shot instead of a 63 g drink saves another 49. Pick the rum you like and fix the glass around it.
Rum FAQs
How many calories are in a shot of rum?
97 calories for a standard 1.5 fl oz shot, which weighs 42 g, at 231 calories per 100 g. That is 80 proof rum, straight, before any mixer or ice. A double, two shots at 84 g, comes to 194 calories.
How many calories are in a rum and Coke?
200 calories for a 225 g drink, which is 89 calories per 100 g. The glass also carries 7.8 g of carbohydrate per 100 g, about 17.6 g in total, and nearly all of it is sugar from the soda. The rum itself contributes none of those carbs.
Does rum have carbs or sugar?
Zero of both: USDA lists plain rum at 0 g of carbohydrate, 0 g of total sugars, 0 g of fat and 0 g of protein per 100 g. Distillation leaves only ethanol and water, so all 231 calories per 100 g come from the alcohol.
Is rum keto-friendly?
Rum has 0 g of carbohydrate, so a 42 g shot adds 97 calories and nothing to a carb budget. The mixer is what breaks it: rum and cola brings 7.8 g of carbohydrate per 100 g, roughly 17.6 g in a 225 g glass, while diet cola keeps it near zero.
Which has fewer calories, rum or vodka?
Neither: both are 231 calories per 100 g at 80 proof, and so are whiskey and tequila, which makes a 1 fl oz pour 65 calories in every case. Proof is what separates spirits: 100 proof rum is 295 calories per 100 g, not the label on the bottle.
How many calories are in 100 proof rum?
295 calories per 100 g, which makes a 1.5 fl oz shot 124 calories instead of 97. That is 27 extra calories for an identical-looking pour, a 28% increase. The steps between are 86 proof at 250 calories per 100 g and 90 proof at 263.
How many calories are in rum and Diet Coke?
135 calories for a 225 g glass, at 60 calories per 100 g. The same drink made with regular cola is 200 calories, so the swap saves 65 calories, all of it sugar. It is the largest single saving available on a rum drink.
Does spiced rum have more calories than white rum?
At 80 proof any rum is 231 calories per 100 g and 97 per shot, and USDA publishes no separate record for spiced rum, so no exact figure exists for it here. What can be said is that proof drives the number, and most spiced bottles are bottled at 70 to 80 proof.
