Our Mission
"Drink 8 glasses a day" is easy to remember but not personalised — it ignores your body size, activity level, and climate. WaterIntakeCalculator.in gives you a personalised daily target and, just as importantly, a realistic schedule for actually drinking it throughout your day.
Our Methodology
Our formula (weight × 35ml, plus exercise and climate adjustments) reflects widely cited hydration guidance. Our drinking schedule distributes your target across roughly 10 natural drinking moments in your day, starting from your wake-up time.
Important: we are an informational tool, not a medical provider. Read our full Disclaimer before making health decisions based on any calculator result.
Editorial Standards
Our content is written to be genuinely useful, not padded for search engines — clear formulas, honest limitations, and practical, actionable guidance.
What We're Building Next
We're exploring push-notification style reminders and a printable schedule format, continuing the same standard: transparent math, no dark patterns, free forever.
