Calories in Beer, Wine & Spirits Calculator
Ethyl alcohol (ethanol) delivers 7 kcal per gram — nearly twice the energy of carbohydrates or protein (4 kcal/g) and approaching that of fat (9 kcal/g). The standard international formula multiplies volume (ml) by ABV, by ethanol density (0.789 g/ml), by 7 kcal/g, then adds residual carbohydrate calories that differ by drink type. Enter your drink type, volume, and ABV to get an accurate calorie count.
Alcohol delivers 7 kcal per gram of ethanol. A 12 oz (354 ml) regular beer at 5% ABV has about 145 kcal; a 5 oz (150 ml) glass of dry red wine at 12.5% has ~125 kcal; a 1.5 oz (45 ml) spirit shot at 40% ABV has ~105 kcal; a 2 oz (60 ml) shot of Fernet at 39% has ~138 kcal. Formula: kcal = volume_ml × (ABV/100) × 0.789 × 7 + residual carb calories.
When to use this calculator
- Tracking calories during a weight-loss diet and want to know what a Friday night adds up to.
- Fitness enthusiasts wanting to account for weekend drinks in their weekly calorie budget.
- Comparing calorie counts before choosing between a craft IPA and a light lager.
- Logging accurate drink calories in a nutrition app alongside food.
Example: 12 oz regular beer at 5% ABV
- Drink type: Regular beer
- Volume: 354 ml
- ABV: 5%
- Ethanol grams: 354 × 0.05 × 0.789 = 13.97 g
- Calories from alcohol: 13.97 × 7 = 98 kcal
- Residual carbs: 354 ml × 3.6 g/100 ml × 4 kcal/g = 51 kcal
- Total: 98 + 51 = 149 kcal ≈ 145 kcal
How it works
2 min readHow it's calculated
The standard formula used by nutritionists and health agencies worldwide:
1. Ethanol grams = volume_ml × (ABV% / 100) × 0.789
(0.789 = density of ethanol in g/ml at room temperature)
2. Calories from alcohol = ethanol_grams × 7
3. Residual carbs (g) = volume_ml × carb_g_per_100ml / 100
4. Calories from carbs = residual_carbs_g × 4
5. Total calories = calories_alcohol + calories_carbsResidual carbohydrates vary by drink type:

Frequently asked questions
How many calories are in a 12 oz (354 ml) regular beer at 5% ABV?
About 145 kcal: approximately 98 kcal from ethanol (354 × 0.05 × 0.789 × 7) plus 51 kcal from residual malt carbohydrates (~3.6 g/100 ml). A pint (500 ml) rises to about 210 kcal.
How many calories in a 5 oz (150 ml) glass of wine at 12.5% ABV?
Around 125 kcal: ~111 kcal from alcohol (150 × 0.125 × 0.789 × 7) plus ~15 kcal from residual sugars in dry wine (~2.5 g/100 ml). Dry white wine is very similar at 118–122 kcal.
How many calories are in a shot of Fernet (60 ml, 39% ABV)?
About 138 kcal: ~128 kcal from ethanol (60 × 0.39 × 0.789 × 7) plus ~29 kcal from the herbal extracts and added sugars (~8 g/100 ml). Mixed with 7 oz of regular cola, the drink adds ~84 kcal more, reaching ~220 kcal total.
How many calories in a 1.5 oz (45 ml) spirit shot at 40% ABV?
About 99–105 kcal, coming entirely from ethanol. Pure spirits (vodka, gin, whiskey, rum) have zero residual carbohydrates. The hidden calories typically come from mixers — regular tonic or soda can add 80–120 kcal per 7 oz.
Why does alcohol have so many calories if it's not a macronutrient?
Ethanol yields 7 kcal per gram — nearly double carbohydrates or protein (4 kcal/g) and close to fat (9 kcal/g). On top of that, your liver prioritizes metabolizing alcohol, effectively pausing fat oxidation for several hours after drinking.
What is the 0.789 constant in the calorie formula?
0.789 g/ml is the density of pure ethanol at room temperature. It converts the volume of alcohol in a drink (derived from the ABV percentage) into mass in grams, so you can then multiply by 7 kcal/g to get calorie content.
Do craft beers have more calories than regular lagers?
Yes, usually significantly more. Higher ABV (6–7%+ vs. 4–5%) and more residual malt extract (~5.5 g/100 ml) both add calories. A 500 ml craft IPA at 6.5% ABV can have 280–320 kcal versus ~210 kcal for a standard 5% pint.
What are the lowest-calorie alcoholic drinks?
Light beer (~85–90 kcal per 12 oz), brut sparkling wine or champagne (~95–100 kcal per 5 oz glass), and pure spirits with zero-calorie mixers (~99–105 kcal per 1.5 oz shot). Hard seltzers (~100 kcal) are also among the lowest.
Can I lose weight while drinking alcohol?
It's possible but harder. Alcohol adds calories without nutrition and slows fat metabolism while it's being processed. Practical strategies: choose lower-ABV drinks, watch serving sizes, avoid sugary mixers, and count drink calories in your daily total just like food.
Does alcohol affect weight loss beyond just its calories?
Yes. Beyond the calorie content, alcohol temporarily suppresses fat oxidation (your body burns it first), can impair sleep quality affecting recovery and hunger hormones, and often leads to increased appetite and less mindful eating choices afterward.
