About
Caffeine Calculator is a simple tool to estimate daily caffeine intake from common drinks like coffee, tea, and energy drinks.
The goal is to provide a quick, practical answer — helping you understand your intake and stay within commonly recommended limits.
What this tool does
The calculator uses average caffeine values and lets you adjust drink type, amount, serving size, and strength. It translates your total into a clear estimate with straightforward guidance.
Who this is for
For anyone who wants a quick sense of their caffeine intake — whether to improve sleep, reduce jitters, or stay within a personal limit.
How estimates are built
Estimates are based on published average ranges. Actual caffeine varies by roast, brew method, brand, and serving size.
This tool is designed to be directionally useful, not exact.
Principles
Simple, transparent, and practical. Detailed information stays optional — the main result remains easy to read at a glance.
