How the calculation works
This calculator estimates the caffeine in soda by using a typical caffeine value for the selected category. Caffeine in soda varies by brand and serving, so the result is an estimate rather than a guarantee.
Diet cola generally has more caffeine than regular cola in the listed typical values. Most lemon-lime and orange sodas are listed as having no caffeine.
The total uses your serving volume and number of servings, so you can account for a container that differs from the source's 355 mL standard serving.
Total caffeine = (category caffeine mg ÷ 355 mL) × serving volume × servings This is general information, not medical advice. A single estimate is not a diagnosis; a clinician decides how caffeine may relate to your health. The FDA says up to 400 mg per day is not generally associated with negative effects for healthy adults, but individual circumstances differ.
