UNDERSTAND THE METHOD
How to use this calculator
Add drinks and edit each serving volume, alcohol percentage, carbohydrate, and serving count. Energy includes ethanol and carbohydrate. A drink with fat or protein can contain additional energy.
What the result can tell you
These results do not estimate blood alcohol concentration, sobriety, or time until it is safe to drive. Energy equivalents are arithmetic comparisons, not weight forecasts or exercise advice. Preset pours and ingredients vary.
Calories in common drinks, and how alcohol calories are counted
Quick answers from the calculator: a 1.5 fl oz (44 mL) shot of 80-proof (40%) tequila, vodka, gin, rum or whiskey is about 96 kcal, and a 25 mL shot about 55 kcal. At 100 proof (50%), the 1.5 fl oz shot is about 120 kcal. A 5 fl oz (148 mL) glass of 13.5% red wine is about 124 kcal, and a 750 mL bottle about 631 kcal. A 16 fl oz US pint of 5% regular beer is about 196 kcal, and a 568 mL UK pint about 236 kcal.
Alcohol calories come from two things: the alcohol itself (ethanol) and the carbohydrate in the drink. The calculator turns the pour into grams of ethanol (mL × alcohol by volume ÷ 100 × 0.789, the density of ethanol in g/mL), counts 6.93 kcal per gram of ethanol and 4 kcal per gram of carbohydrate, and adds them. For example, a 12 fl oz (355 mL) regular beer at 5% holds 14.00 g of ethanol, about 97 kcal, plus 12.6 g of carbohydrate, so about 147 kcal in all.
Calories in one serving of each preset drink
| Drink | Calories | Serving | Alcohol by volume | Carbs | Ethanol | US standard drinks |
|---|---|---|---|---|---|---|
| Regular beer | 147 kcal | 12 fl oz (355 mL) | 5% | 12.6 g | 14.00 g | 1.00 |
| Light beer | 105 kcal | 12 fl oz (355 mL) | 4.2% | 5.8 g | 11.76 g | 0.84 |
| Craft / IPA | 188 kcal | 12 fl oz (355 mL) | 6.8% | 14 g | 19.05 g | 1.36 |
| Red wine | 124 kcal | 5 fl oz (148 mL) | 13.5% | 3.8 g | 15.76 g | 1.13 |
| White wine | 116 kcal | 5 fl oz (148 mL) | 12.5% | 3.8 g | 14.60 g | 1.04 |
| Sparkling wine | 105 kcal | 5 fl oz (148 mL) | 12.2% | 1.6 g | 14.25 g | 1.02 |
| Dessert wine | 136 kcal | 3 fl oz (89 mL) | 18% | 12 g | 12.64 g | 0.90 |
| Spirits | 96 kcal | 1.5 fl oz (44 mL) | 40% | 0 g | 13.89 g | 0.99 |
| Mixed cocktail | 176 kcal | 1.5 fl oz spirit (44 mL) plus mixer | 40% (spirit) | 20 g | 13.89 g | 0.99 |
| Hard seltzer | 105 kcal | 12 fl oz (355 mL) | 5% | 2 g | 14.00 g | 1.00 |
The carbohydrate figures are the calculator's preset values, and the mixed cocktail counts one 1.5 fl oz shot of 40% spirit plus 20 g of carbohydrate from the mixer. Brands and pours vary, so enter the volume, alcohol by volume and carbohydrate from your own drink's label in the calculator above.
Calories from the alcohol alone, by strength
| Alcohol by volume | Ethanol per 100 mL | Per 100 mL | Per US fl oz |
|---|---|---|---|
| 4% | 3.16 g | 22 kcal | 6 kcal |
| 5% | 3.95 g | 27 kcal | 8 kcal |
| 6% | 4.73 g | 33 kcal | 10 kcal |
| 8% | 6.31 g | 44 kcal | 13 kcal |
| 10% | 7.89 g | 55 kcal | 16 kcal |
| 12% | 9.47 g | 66 kcal | 19 kcal |
| 13.5% | 10.65 g | 74 kcal | 22 kcal |
| 15% | 11.84 g | 82 kcal | 24 kcal |
| 20% | 15.78 g | 109 kcal | 32 kcal |
| 40% | 31.56 g | 219 kcal | 65 kcal |
This table leaves out carbohydrate, so a sweet drink has more calories than its row shows. Add the label's carbohydrate grams × 4 to get the total.
Calories in a shot of straight spirit, by pour and strength (US proof)
| Pour | 35% (70 proof) | 40% (80 proof) | 43% (86 proof) | 45% (90 proof) | 50% (100 proof) |
|---|---|---|---|---|---|
| 0.8 fl oz (25 mL) | 48 kcal | 55 kcal | 59 kcal | 62 kcal | 68 kcal |
| 1 fl oz (30 mL) | 57 kcal | 66 kcal | 71 kcal | 74 kcal | 82 kcal |
| 1.5 fl oz (44 mL) | 84 kcal | 96 kcal | 103 kcal | 108 kcal | 120 kcal |
| 2 fl oz (59 mL) | 113 kcal | 129 kcal | 139 kcal | 145 kcal | 161 kcal |
The type of straight spirit does not change the count: at the same strength and pour, tequila, vodka, gin, rum and whiskey give the same number here, and the MedlinePlus figures further down give one number for gin, rum, vodka and whiskey at each proof. Liqueurs, and many flavored spirits and mixers, can add sugar; check the label.
Calories in wine, by glass size and bottle
| Pour | Red wine (13.5%) | White wine (12.5%) | Sparkling wine (12.2%) |
|---|---|---|---|
| 125 mL (4.2 fl oz) | 105 kcal | 98 kcal | 89 kcal |
| 148 mL (5 fl oz) | 124 kcal | 116 kcal | 105 kcal |
| 175 mL (5.9 fl oz) | 147 kcal | 138 kcal | 124 kcal |
| 250 mL (8.5 fl oz) | 210 kcal | 197 kcal | 178 kcal |
| Bottle, 750 mL (25.4 fl oz) | 631 kcal | 590 kcal | 533 kcal |
Calories in beer and hard seltzer, by size
| Size | Light beer (4.2%) | Regular beer (5%) | Craft / IPA (6.8%) | Hard seltzer (5%) |
|---|---|---|---|---|
| 12 fl oz (355 mL) | 105 kcal | 147 kcal | 188 kcal | 105 kcal |
| US pint, 16 fl oz (473 mL) | 140 kcal | 196 kcal | 250 kcal | 140 kcal |
| UK pint, 568 mL (19.2 fl oz) | 168 kcal | 236 kcal | 301 kcal | 168 kcal |
| 24 fl oz (710 mL) | 209 kcal | 295 kcal | 376 kcal | 210 kcal |
The wine, beer and seltzer rows scale each preset's carbohydrate with the pour, so a 750 mL bottle counts 5.1 times the carbohydrate of a 148 mL glass. A sweeter wine or a stronger beer than the preset has more calories than its row.
For the same kinds of drink the calculator's presets give: 80-proof shot 96, regular beer 147, light beer 105, red wine 124 and white wine 116 kcal. The margarita has no matching preset. Small gaps are expected, because strength, carbohydrate and pour size differ a little between sources.
These mixed drink figures are MedlinePlus's, for its serving sizes, not results from this calculator. Recipes and glass sizes vary, so a larger glass or a sweeter mixer has more. Rum with Diet Coke has 85 fewer calories than rum with regular Coke in the same 8 fl oz glass. Cream and butter add fat, which the calculator does not count, so for a drink like a White Russian it shows less than the real total. For other drinks, enter each spirit or liqueur pour and the mixer's carbohydrate from its label in the calculator above.
Common questions
How are drink calories calculated?
Enter serving volume, alcohol by volume, carbohydrate, and servings. The calculator converts alcohol to ethanol grams, then adds energy from ethanol and carbohydrate.
Does this result show blood alcohol concentration or sobriety?
No. It shows energy, ethanol, and standard-drink comparisons. It does not estimate blood alcohol concentration, sobriety, or the time until it is safe to drive.
How many calories are in a beer, a glass of wine or a shot?
With this calculator's presets, a 12 fl oz regular beer at 5% is about 147 kcal, a 5 fl oz glass of red wine at 13.5% is about 124 kcal, and a 1.5 fl oz shot of 40% spirits is about 96 kcal. The beer and the shot each hold about one US standard drink (14 g of alcohol); the 13.5% wine holds about 1.1. Carbohydrate and pour size change the total, so check your drink's label.
How many calories are in a shot of tequila or vodka?
A 1.5 fl oz (44 mL) shot of 80-proof (40%) tequila or vodka is about 96 kcal with this calculator, and a 25 mL shot is about 55 kcal. A 1.5 fl oz shot at 100 proof (50%) is about 120 kcal. In this calculator, tequila, vodka, gin, rum and whiskey at the same strength and pour give the same number. Liqueurs, and many flavored spirits and mixers, can add sugar; check the label.
How many calories are in a bottle of wine?
A 750 mL bottle of 13.5% red wine is about 631 kcal with this calculator's preset carbohydrate, and a 12.5% white is about 590 kcal. A bottle holds just over five 5 fl oz (148 mL) glasses (about 124 kcal each for the red). Stronger or sweeter wine has more.
How many calories are in a pint of beer?
A 16 fl oz (473 mL) US pint of 5% regular beer is about 196 kcal with this calculator's presets, a 4.2% light beer about 140 kcal and a 6.8% craft beer or IPA about 250 kcal. A UK pint (568 mL) of 5% regular beer is about 236 kcal. Strength and carbohydrate vary by brand, so check the label.
How many calories are in a margarita?
MedlinePlus lists 168 calories for a 4 fl oz (120 mL) margarita. A bigger glass or a sweeter mix has more. The same MedlinePlus list gives 143 calories for a 6 fl oz mojito and 189 for a 7 fl oz vodka and tonic. To count your own, enter each spirit or liqueur pour and the mixer's carbohydrate in the calculator.
