Alcohol calories = volume (mL) × ABV% ÷ 100 × 0.789 g/mL × 7 kcal/g, plus 4 kcal per gram of residual sugar or carbohydrate. Sanity check: a 355 mL beer at 5% ABV contains 14.0 g of ethanol — exactly one US standard drink — which is 98 kcal before its 12.6 g of carbohydrate takes it to about 148 kcal.

What that adds up to

A year of weeks like this is about 82,535 kcal, which at the classic 3,500 kcal per pound is roughly 23.6 lb (10.7 kg) of energy — assuming you do not eat any less to make room for it.

That is 21.9 UK units and 12.5 standard drinks on the definition you picked. The UK Chief Medical Officers advise no more than 14 units a week, spread over three or more days; US guidance suggests at most 2 drinks a day for men and 1 for women; Australia advises no more than 10 standard drinks a week.

Estimates only, not medical advice. Alcohol labels round their ABV, pours at home are famously bigger than the measures used here, and the residual sugar in wine, cider and cocktails varies enormously between products — a dry white and a dessert wine at the same ABV can be 60 kcal apart per glass. The calorie arithmetic also says nothing about alcohol's other health effects. If you are worried about your drinking, speak to a doctor or a service such as Drinkline, SAMHSA's helpline or your local equivalent.

What is the Alcohol Calories Calculator?

Calories from alcohol equal the drink's volume in millilitres × ABV percentage ÷ 100 × 0.789 g/mL × 7 kcal per gram, plus 4 kcal for every gram of residual sugar or carbohydrate.

  • Seventeen presets covering beer, cider, wine, spirits, seltzers and cocktails
  • Separates calories from alcohol and calories from residual sugar or carbohydrate
  • Standard drink counting for the US, UK, Australia, Canada, Germany and the WHO definition
  • Weekly and yearly totals, with the equivalent in pounds and kilograms of stored energy
  • Millilitre and US fluid ounce entry, converted for you when you switch
  • Fully offline in your browser — nothing about your drinking is uploaded

How to use the Alcohol Calories Calculator

  1. 1

    Choose whether to enter volumes in millilitres or US fluid ounces, and pick the standard drink definition for your country.

  2. 2

    For each drink, select a preset — the volume, ABV and carbohydrate figures fill in automatically — or leave it on Custom.

  3. 3

    Adjust the volume, ABV and carbohydrate grams to match what you actually drink, and rename the row if you like.

  4. 4

    Set how many of each drink you have in a typical week, and use Add drink for anything missing.

  5. 5

    Read the per-drink calories under each row, then the weekly totals, the breakdown table and the yearly summary.

About the Alcohol Calories Calculator

The ByteTools Alcohol Calories Calculator works out what a week of drinking is actually worth in calories. Pick from seventeen common drink presets or enter your own volume, ABV and carbohydrate figure, say how many you have in a typical week, and it shows the calories per drink and the weekly total split between alcohol and sugar.

It counts standard drinks too, on whichever definition you use — 14 g in the United States, an 8 g UK unit, 10 g in Australia and for the WHO, 13.45 g in Canada or 12 g in Germany. Changing that setting never changes the calorie figures, only how the same ethanol is counted, which is exactly why the same pint reads as different numbers of drinks in different countries.

Everything is computed locally in your browser and nothing is uploaded or stored. These are estimates, not medical advice: labels round their ABV, home pours are usually larger than the measures used here, and residual sugar varies enormously between products.

Frequently asked questions

How many calories are in a beer?

A standard 12 fl oz (355 mL) beer at 5% ABV contains 14 g of ethanol, which is 98 kcal, plus about 12.6 g of carbohydrate at 4 kcal per gram — roughly 148 to 155 kcal in total. A light beer at 4.2% with far less residual sugar comes in nearer 100 kcal.

How do you calculate calories from alcohol?

Multiply the volume in millilitres by the ABV percentage divided by 100 to get the millilitres of pure ethanol, multiply by 0.789 to convert to grams, then multiply by 7 kcal per gram. Anything left over as sugar or carbohydrate adds 4 kcal per gram on top.

Why is alcohol 7 calories per gram?

Ethanol sits between carbohydrate and protein at 4 kcal per gram and fat at 9. Your body oxidises it for energy but cannot store it, so it takes metabolic priority — which is part of why alcohol calories are often described as displacing fat burning rather than simply adding up.

How many units is a pint of beer?

A 568 mL UK pint at 4% ABV contains about 17.9 g of ethanol, which is roughly 2.2 UK units at 8 g per unit. The same pint counts as about 1.3 US standard drinks or 1.8 Australian ones — same drink, different definitions.

Does wine have fewer calories than beer?

Per glass, usually yes, but per unit of alcohol usually not. A 148 mL glass of 13.5% red wine is about 125 kcal against a 355 mL beer's 150, but the wine contains slightly more ethanol. Beer's extra calories come from carbohydrate; wine's come almost entirely from the alcohol itself.

Are my drink entries saved anywhere?

No. The calculator runs entirely in your browser using JavaScript. Nothing you type is uploaded, logged or retained, and the page works with no network connection at all.
