The Caffeine Limit Calculator is a simple yet powerful tool designed to help you understand how much caffeine you are consuming in a day. Many people drink coffee, tea, energy drinks, or espresso without realizing how quickly caffeine levels add up.

Practical Example
Let’s understand how this calculator works in real life.
Example Scenario:
A person consumes:
- 2 cups of coffee
- 1 cup of tea
- 1 energy drink
- 2 espresso shots
Calculation:
- Coffee: 2 × 95 = 190 mg
- Tea: 1 × 47 = 47 mg
- Energy Drink: 1 × 80 = 80 mg
- Espresso: 2 × 63 = 126 mg
Total Caffeine:
190 + 47 + 80 + 126 = 443 mg
Result:
- Total Intake: 443 mg
- Status: ⚠ Above Safe Limit
This shows the person is slightly over the recommended daily caffeine limit and may need to reduce intake.
