Choose the Right ETG Calculator
Pick the tool that matches your question: main urine test estimate, cutoff timeline, half-life math, or elimination window.
Start with the tool that matches your test question
Use the main ETG calculator for a full urine test estimate. Use the chart for a visual cutoff timeline, and the smaller tools when you want to isolate one part of the model.
Need one answer?
Start with the full calculator. It combines drinking amount, time elapsed, cutoff level, and personal factors.
Need a timeline?
Use the chart to see when ETG crosses standard 500 ng/mL and strict 100 ng/mL cutoffs.
Need the math?
Use half-life and elimination tools to understand decay, clearance, and why estimates vary.
Choose the Right ETG Calculator
Full ETG Calculator
Best first stop for a urine test estimate with drink count, time elapsed, cutoff level, and personal factors.
Interactive Detection Chart
Best for seeing when ETG crosses 500 ng/mL and 100 ng/mL cutoffs across different drinking amounts.
Alcohol ETG Calculator
Best for a quick estimate based mainly on what and how much you drank.
ETG Half-Life Calculator
Best for understanding the decay curve and how cutoff thresholds change the risk window.
ETG Elimination Calculator
Best for estimating when ETG should fall below common testing thresholds.
