About this tool
Mixing spirits with juice or soda lowers the alcohol percentage, and this calculator finds the final strength from the spirit volume, its ABV, and the mixer volume. It assumes the volumes add together, which is close enough for home drinks. Drink responsibly and never drive after drinking.
Frequently asked questions
Does ice change the ABV?
Yes, as ice melts it adds water and dilutes the drink further, so the served strength falls over time.
What counts as one standard drink?
It varies by country. Check your local guidance rather than assuming one glass equals one standard drink.
