About this calculator
What this calculator measures
See how your daily caffeine intake compares with a relevant reference population. The comparison uses the reference population and evidence identified on this page.
How to interpret your result
A percentile describes the approximate percentage of the stated reference population with a lower value. When a source supports only categories, medians, or averages, Humanlytic shows that broader comparison instead of inventing an exact percentile.
