Formula and methodology
Formula: Weight-based scenario = body weight × selected sensitivity factor; planning limit = min(weight-based scenario, entered daily limit); planned caffeine = servings × caffeine per serving; remaining = planning limit − planned caffeine.
Coffee strength and serving sizes vary widely. This page does not assign a universal personal limit; it keeps the beverage label, a chosen scenario factor, and the visitor's comparison limit visible so the arithmetic can be checked or replaced.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Body weight — kg; minimum 0.1; maximum 500
- Sensitivity scenario — 4 choices
- Caffeine per serving — mg; minimum 0.001; maximum 2000
- Planned servings — servings; minimum 0; maximum 100
- Your comparison limit — mg/day; minimum 0.001; maximum 5000
Worked example
| Input | Value |
|---|---|
| Body weight | 70 |
| Sensitivity scenario | typical |
| Caffeine per serving | 95 |
| Planned servings | 3 |
| Your comparison limit | 400 |
The lower planning limit is 400 mg/day; three 95 mg servings total 285 mg, leaving 115 mg in this scenario.
Assumptions and limits
- Body weight and caffeine quantities use kilograms and milligrams as labeled.
- The sensitivity factor is a planning scenario, not a clinical dose rule or a diagnosis of tolerance.
- The entered daily limit is a visitor-supplied comparison value and may be changed for a product, policy, or professional instruction.
- Caffeine per serving should come from the actual package, café specification, or other current label source.
- Servings can represent coffee, tea, energy drinks, or another beverage if the caffeine value is entered consistently.
- Medication interactions, pregnancy, age, sleep, medical conditions, and individual responses are outside the arithmetic.
- A negative remaining result means the entered scenario has been exceeded; it is not a diagnosis of toxicity.
