The Caffeine Calculator helps estimate your daily caffeine intake by selecting different drinks and the number of servings consumed. Caffeine intake varies by drink type, and excessive consumption can lead to health issues such as insomnia, anxiety, and heart palpitations. This calculator provides an easy way to track caffeine intake and make informed decisions about consumption.
Formula
Instead of using a standard formula, this calculator references an estimated caffeine content table for each drink and multiplies it by the number of cups consumed.
Formula:
Total Caffeine Intake = Caffeine per Drink × Number of Cups
This is an approximation, and actual caffeine content may vary based on brand and preparation method.
How to Use
- Select a drink type from the dropdown menu.
- Enter the number of cups consumed.
- Click the "Calculate" button.
- The calculator will display the total caffeine intake in milligrams (mg).
Example
Suppose:
- Drink Type: Brewed Coffee (8 oz) – 95 mg per cup
- Number of Cups: 3
Using the formula:
Total Caffeine Intake = 95 × 3 = 285 mg
So, the total caffeine intake is 285 mg.
