Estimated caffeine remaining over time
These figures apply CaffCalc’s exponential model to the adjusted 260.0 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 | 260.0 mg | 260.0 mg | 260.0 mg |
| 3 | 130.0 mg | 171.5 mg | 193.2 mg |
| 5 | 81.9 mg | 130.0 mg | 158.5 mg |
| 8 | 40.9 mg | 85.8 mg | 117.7 mg |
| 10 | 25.8 mg | 65.0 mg | 96.6 mg |
| 12 | 16.3 mg | 49.3 mg | 79.2 mg |
With the central five-hour model, the estimate falls below 25 mg after approximately 16.9 hours. The faster and slower columns show why one fixed clearance time should not be treated as a personal fact.
