Estimated caffeine remaining over time
These figures apply CaffCalc’s exponential model to the adjusted 60 mg starting value. They are calculations, not measurements of caffeine in a particular person.
| Hours elapsed | 3-hour half-life | 5-hour half-life | 7-hour half-life |
|---|---|---|---|
| 0 | 60 mg | 60 mg | 60 mg |
| 3 | 30 mg | 39.6 mg | 44.6 mg |
| 5 | 18.9 mg | 30 mg | 36.6 mg |
| 8 | 9.4 mg | 19.8 mg | 27.2 mg |
| 10 | 6.0 mg | 15 mg | 22.3 mg |
| 12 | 3.8 mg | 11.4 mg | 18.3 mg |
With the central five-hour model, the estimate falls below 25 mg after approximately 6.3 hours. The faster and slower columns show why one fixed clearance time shouldn’t be treated as a personal fact.
