Estimated caffeine remaining over time
These figures apply CaffCalc’s exponential model to the adjusted 325 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 | 325 mg | 325 mg | 325 mg |
| 3 | 162.5 mg | 214.4 mg | 241.5 mg |
| 5 | 102.4 mg | 162.5 mg | 198.1 mg |
| 8 | 51.2 mg | 107.2 mg | 147.2 mg |
| 10 | 32.2 mg | 81.3 mg | 120.7 mg |
| 12 | 20.3 mg | 61.6 mg | 99.0 mg |
With the central five-hour model, the estimate falls below 25 mg after approximately 18.5 hours. The faster and slower columns show why one fixed clearance time should not be treated as a personal fact.
