Sobering Time Calculator
Calculate When You'll Be Sober
Determine when you'll be sober enough for specific activities based on your current alcohol consumption and personal factors.
How Sobering Time Calculation Works
Current BAC Assessment
Calculate your current blood alcohol content using the Widmark formula and time elapsed since drinking.
Target BAC Level
Determine the required BAC level for your intended activity, from complete sobriety to legal limits.
Metabolism Rate
Apply the standard alcohol elimination rate of 0.015% BAC per hour to calculate sobering time.
Timeline Generation
Create a detailed timeline showing your BAC progression and when you'll reach your target level.
BAC Requirements for Different Activities
Driving
Complete sobriety is recommended for safe driving. Even legal BAC levels can impair reaction time and judgment.
Work/Professional
Most workplaces require complete sobriety. Any alcohol presence can affect performance and safety.
Legal Driving Limit
Legal limit in most jurisdictions, but impairment begins at lower levels. Not recommended for safe driving.
Light Activities
Suitable for light social activities where minimal impairment is acceptable. Avoid driving or important decisions.
Understanding Alcohol Elimination
Key Facts About Alcohol Elimination
- Fixed Rate: Your body eliminates alcohol at approximately 0.015% BAC per hour
- Cannot Be Accelerated: Coffee, cold showers, or exercise don't speed up elimination
- Individual Variation: Age, health, and genetics can affect elimination rates
- Time is the Only Cure: Only time allows your liver to process alcohol completely

Frequently Asked Questions
Can I speed up the sobering process?
No, there is no way to speed up alcohol elimination. Your liver processes alcohol at a fixed rate of about 0.015% BAC per hour. Coffee, cold showers, exercise, or other remedies don't accelerate this process - only time works.
How accurate are sobering time estimates?
Our calculator uses scientifically validated formulas and provides good estimates for most people. However, individual factors like age, health, medications, and genetics can affect actual elimination times. Always err on the side of caution.
Is it safe to drive at the legal BAC limit?
While 0.08% BAC is the legal limit in most places, impairment begins at much lower levels. For maximum safety, we recommend waiting until your BAC is 0.00% before driving. Even legal BAC levels can significantly impair reaction time and judgment.
What if I feel sober but still have alcohol in my system?
Feeling sober doesn't mean you are sober. Alcohol can impair judgment about your own impairment level. Always wait until your calculated BAC reaches your target level, and assess how you actually feel before proceeding with activities.
Should I eat food or drink coffee while sobering up?
Eating light, nutritious food and staying hydrated with water can help you feel better, but they don't speed up alcohol elimination. Coffee might make you feel more alert but doesn't reduce your BAC. Avoid heavy meals that might upset your stomach.
