Alcohol Calorie Calculator
Alcohol is 7 calories per gram — second only to fat — and almost no nutrition apps log it correctly. This calculator gives you the real number for any drink, plus quick reference values for beer, wine, and common cocktails.
Calculate Your Drink
Beer ~5%, wine ~12%, vodka/whiskey/gin ~40%, light beer ~4%.
Tonic, juice, soda, syrup. Often more than the alcohol itself in cocktails.
Quick Reference: Common Drinks
- Light beer (12 oz, 4% ABV): ~95 kcal
- Regular beer (12 oz, 5% ABV): ~150 kcal
- IPA (12 oz, 7% ABV): ~200–230 kcal
- Red or white wine (5 oz, 12% ABV): ~120 kcal
- Champagne (5 oz, 12% ABV): ~95 kcal
- Vodka soda (1.5 oz vodka, 40% ABV, no calorie mixer): ~95 kcal
- Gin & tonic (1.5 oz gin + 4 oz tonic): ~190 kcal
- Margarita (typical bar pour): ~250–400 kcal
- Piña colada / frozen drinks: ~400–600 kcal
- Long Island iced tea: ~500–700 kcal
The hidden cost is usually the mixer. A vodka soda is one of the leanest drinks. The same vodka in a sugared cocktail can triple the calories.
What Alcohol Actually Does to Fat Loss
Alcohol doesn't directly "turn into fat" — that's an oversimplification. What it does is more interesting and more annoying for people in a deficit:
- Priority oxidation. The liver processes alcohol first. While it does, fat oxidation is suppressed — your body stops burning stored fat until the alcohol is cleared.
- Calorie displacement. Alcohol calories don't trigger satiety hormones like protein or fat do, so they stack on top of your normal intake instead of replacing it.
- Disinhibited eating. The well-documented effect of late-night drinking on food choices. The drinks themselves are rarely the worst part of a night out.
- Disrupted sleep. Even 1–2 drinks reduce REM and slow-wave sleep, which is when most muscle recovery and growth hormone release happens.
- Blunted muscle protein synthesis. Studies show heavy drinking after training can suppress MPS by 24–37% even when protein intake is adequate.
Moderate drinking (1–2 drinks, 1–2 nights per week) doesn't meaningfully derail well-built fat loss. Heavy or daily drinking does, and the cumulative effect is more than the calorie count alone suggests.
The Practical Takeaway
- Pick clear spirits + zero-calorie mixers if you drink during a cut. Vodka soda, gin & soda, tequila & soda all run ~95 kcal per drink.
- Wine and light beer are the best wine/beer options at ~95–120 kcal per serving.
- Avoid sugary cocktails. A margarita or piña colada can cost 3–5x a vodka soda.
- Drink earlier, not later. Reduces sleep impact and the post-drink food spiral.
- Hit your protein anyway. Drinking is a worse hit when total daily protein is low; the muscle preservation buffer matters most when other levers slip.
