Alcohol calculator Alcohol calculator

Online alcohol elimination time calculator

The calculation uses a simplified Widmark model: alcohol amount, body weight, distribution ratio and an average alcohol elimination rate.

The result is reference only. It does not account for health conditions, medication, food, individual metabolism, exact drink content or legal thresholds.

Use the calculator to turn input values into a clear, repeatable result.
Keep units and assumptions visible so the calculation can be checked later.
Copy the result or key numbers for reports, messages or spreadsheets.
Reset to defaults when you want to compare another scenario from a clean state.
Calculators run in the browser and are useful for quick estimates before formal checks.
For finance, health, engineering or legal decisions, verify important results with a specialist or official source.
