AUDIT-C is a standard, published 3-question brief screening tool for problem drinking, scoring frequency of drinking, typical quantity, and frequency of binge drinking, each 0-4, for a total 0-12 score. This calculator is for general reference and educational purposes only — it is not a medical diagnosis. Consult a doctor or qualified professional for an actual assessment.
How it works
Answer the 3 standard AUDIT-C questions using the dropdown options, and select your sex (the published risk threshold differs by sex). The tool sums your answers and compares against the published threshold.
- Enter sex.
- Enter how often do you have a drink containing alcohol?.
- Enter how many standard drinks do you have on a typical day when drinking?.
- Enter how often do you have 6 or more drinks on one occasion?.
- Click Calculate to see your results.
Examples
A man scoring 2 on each question
Total = 2+2+2 = 6, at or above the male threshold of 4 — positive screen, further evaluation suggested.
Who should use it
- Quick self-screening before a doctor visit to help guide the conversation.
- Research and public health screening programs.
Industry applications
- Primary care screening
- Public health and addiction medicine research
Advantages
- Quick — only 3 questions — while retaining good screening performance in published research.
- Widely used in primary care and research settings.
Limitations
- A brief screen, not as comprehensive as the full 10-question AUDIT.
- Self-reported answers may under- or over-estimate actual drinking patterns.
Common mistakes to avoid
- Answering based on an atypical period (e.g. a holiday) rather than typical, usual drinking habits.
- Treating a positive screen as a diagnosis rather than a signal to seek further evaluation.
Best practices
- Answer honestly based on your typical drinking pattern over the recent past for a meaningful score.
Tips
- If your score suggests further evaluation, bring it up directly with a doctor rather than self-diagnosing.
