A cocktail ABV calculator determines the final alcohol by volume of a mixed drink based on its ingredients. Whether you are crafting a new recipe or checking how strong your favorite cocktail really is, knowing the exact ABV helps you drink responsibly and build balanced drinks every time.

How to Use the Cocktail ABV Calculator
Knowing the exact alcohol content of a mixed drink is important for responsible drinking, recipe development, and understanding how cocktail ratios affect strength. The Cocktail ABV Calculator does the math for you — just enter your ingredients, their volumes, and their individual ABV percentages, and the tool instantly computes the final alcohol by volume of the finished drink.
Step 1: Add your ingredients
Use the ingredient preset dropdown to quickly add common spirits like vodka, gin, rum, whiskey, or tequila at their standard ABV. You can also type a custom ingredient name and set any ABV percentage. Mixers like juice, soda, and simple syrup should be set to 0% ABV. Add up to 8 ingredients per drink.
Step 2: Enter volumes
Type the volume of each ingredient in fluid ounces. A standard cocktail might use 2 oz of spirit, 1 oz of liqueur, and 0.75 oz of citrus juice. The tool accepts decimal values, so you can be as precise as you need — quarter-ounce and half-ounce pours are common in bartending.
Step 3: Toggle ice dilution (optional)
When you shake or stir a cocktail with ice, the ice melts and adds roughly 25% more water to the drink. This dilution is an intentional part of cocktail making — it softens the alcohol burn and balances flavors. Enable the "Account for ice dilution" toggle to see the realistic ABV of the drink as it would be served, rather than just the pre-dilution strength.
Step 4: Read the results
After clicking Calculate ABV, you will see four key metrics: the final ABV percentage, total drink volume, pure alcohol content in ounces, and the number of standard drinks (based on the US definition of 0.6 oz pure alcohol per standard drink). The strength category — Light, Medium, Strong, or Very Strong — gives you a quick sense of how the drink compares to common beverages. The ingredient breakdown table shows exactly how much alcohol each component contributes, helping you understand which ingredient drives the drink's strength.
Understanding the strength categories
Drinks under 10% ABV are classified as Light — comparable to beer or a light spritzer. Medium drinks (10-20%) are in wine territory. Strong drinks (20-30%) include most classic cocktails like Margaritas and Manhattans. Very Strong drinks above 30% ABV are spirit-forward cocktails like Martinis and Negronis, approaching the strength of neat spirits.
FAQ
Is the Cocktail ABV Calculator free to use?
Yes, the Cocktail ABV Calculator is completely free. There is no signup, no account, and no download required. All calculations happen right in your browser.
Is my data private?
Yes. Everything runs locally in your browser. Your ingredient list and drink recipes are never sent to any server or stored anywhere outside your device.
How is the final ABV calculated?
The calculator multiplies each ingredient's volume by its ABV percentage to find the pure alcohol content. It then divides the total alcohol by the total liquid volume and multiplies by 100 to get the final ABV percentage. If ice dilution is enabled, 25% extra water volume is added before dividing.
What is a standard drink?
In the United States, one standard drink contains 0.6 fluid ounces (14 grams) of pure alcohol. This is roughly equivalent to 12 oz of beer at 5%, 5 oz of wine at 12%, or 1.5 oz of spirits at 40%. The calculator uses this definition to estimate standard drink equivalents.
Why does ice dilution affect ABV?
When a cocktail is shaken or stirred with ice, the ice melts and adds water to the drink — typically about 25% of the total volume. This extra water dilutes the alcohol, lowering the final ABV. Enabling the dilution toggle gives you a more realistic ABV for served cocktails.
What do the strength categories mean?
The tool classifies drinks into four categories based on final ABV: Light (under 10%, like a spritzer), Medium (10-20%, like most wine cocktails), Strong (20-30%, like a Margarita), and Very Strong (over 30%, like a Martini or Negroni). These categories help you gauge how potent your drink is.
Can I add custom ingredients with any ABV?
Yes. You can add up to 8 ingredients and set any ABV percentage from 0% to 100% for each one. Use the preset dropdown for common spirits, or type in any custom name and ABV. Mixers like juice and soda should be set to 0% ABV.
