What is Calories in Alcohol?
The Calories in Alcohol calculation tells you your calories from alcohol from a few simple inputs. The figure you are solving for here is the calories from alcohol.
The Calories in Alcohol formula
The core formula is:

- Alcohol by volume (ABV) — a percentage, such as an annual rate. Example: 5%.
How to calculate it step by step
- Write down the drink volume (for example, 500 ml).
- Write down the alcohol by volume (abv) (for example, 5%).
- Apply the formula above to get your calories from alcohol.
- Double-check the result with the Calories in Alcohol Calculator.

| Calories from alcohol | 69 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
- These figures are general estimates, not medical advice — check with a qualified professional before acting on them.
