ABV calculator
Add your ingredients, choose your preparation method, and get ABV with and without dilution, grams of alcohol, and unit count. Enter your actual measured serve volume for the most accurate reading.
Ingredients
0 ml pre-dilution
Preparation method
I measured the actual serve volume
Actual volume after straining (ml)
Strain your finished drink into a jigger or weigh it (1 g ≈ 1 ml for cocktails). When filled in, this becomes the primary result — the estimated dilution moves to a reference row.
Primary result is driven by your measured volume

How it’s calculated
Base ABV
(∑ abv × vol) ÷ total vol
Weighted average across all ingredients.
Estimated dilution
Shaken ~35% • Stirred ~25%
Water added as % of pre-dilution volume. Anecdotal industry estimate — sources to be confirmed.
ABV (estimated)
alc ml ÷ (vol × (1 + dil%))
Same alcohol; larger total volume.
ABV (measured)
alc ml ÷ actual serve ml
Most accurate. Strain into a jigger or weigh the pour.
Grams of alcohol
pure alc ml × 0.789
Fixed regardless of dilution method.
Units
grams ÷ threshold
EU/NL 10g • UK 8g • US 14g per unit.
