AI-Powered BAC Calculator

The AI BAC (Blood Alcohol Concentration) Calculator uses advanced artificial intelligence to provide a personalised and accurate prediction of how alcohol will affect you. By analysing factors like weight, gender, age, and alcohol consumption, our AI estimates your BAC and predicts the time it will take to sober up.

Why is AI more accurate than traditional BAC calculators?

  • Personalisation: Unlike traditional calculators that use generic formulas, our AI adapts to your specific biological factors.
  • Data-Driven Learning: The AI learns from vast datasets of real-world BAC measurements and physiological responses to continuously improve its accuracy.
  • Complex Variables: Our AI can incorporate additional factors like food intake, drinking pace, and physical activity for a more comprehensive analysis.
  • Context-Aware Recommendations: The AI provides more than just numbers; it offers guidance on safety, such as when it is safe to drive, based on your context.

Data used for calculations

Seven factors that determine your result

Weight
Body weight determines how alcohol distributes in the body — more weight means a lower blood alcohol concentration.
Sex
Men and women metabolise alcohol at different rates because of differences in body water content.
Age
Body water content declines with age, so the same amount of alcohol pushes peak BAC higher.
Amount
The amount of pure alcohol consumed is the main factor that determines your BAC result.
Strength
A higher strength (%) means more ethanol in the same drink serving.
Food
Food in your stomach slows alcohol absorption — drinking on an empty stomach can nearly double the peak BAC.
Time
The time of your first drink shows how BAC changes hour by hour and when you'll be sober again.

Drink Driving in Ireland

Drink-driving limits in Ireland (blood alcohol)

Experienced drivers
50mg/100ml
Moderate
Learner & professional drivers
20mg/100ml
Strict
The 20 mg/100ml limit (0.02% BAC) applies to learner permit holders, newly qualified drivers (first 2 years) and professional drivers (HGV, bus, taxi, public service vehicles). Penalties under the Road Traffic Act start at automatic disqualification — even a single drink can put you over the limit.

  • Fixed-charge penalty €200 (50–80 mg) or €400 (80–100 mg)
  • Automatic 3-month disqualification (50–80 mg) or 6 months (80–100 mg)
  • No court appearance if accepted
100+ mg/100 ml (court conviction)
  • Court fine up to €5,000 and/or 6 months imprisonment

Tips for Responsible Drinking

Practical tips for safer drinking

Pace yourself
Stick to the "one drink per hour" rule – your liver needs time to process alcohol.
Eat before and while drinking
A solid meal slows alcohol absorption – an empty stomach raises BAC faster.
Drink water
After each alcoholic drink, have a glass of water – it reduces dehydration and health risks.
Don't drive
Even small amounts of alcohol impair reaction time. If in doubt, call a taxi or stay overnight.
