About this calculator
This calculator estimates your daily caffeine intake based on common coffee types. Actual caffeine content can vary by brand, roast, preparation method, and serving size. For most healthy adults, up to 400 mg of caffeine per day is generally considered safe. During pregnancy or while breastfeeding, many guidelines suggest limiting intake to about 200 mg per day. Individual sensitivity varies—if you have health concerns or symptoms like jitteriness, palpitations, or sleep issues, consider reducing intake and consult a healthcare professional.
