Water Intake Calculator

What is the Water Intake Calculator?

Wondering how much water you really need every day? Our Water Intake Calculator helps you set realistic hydration goals based on your body and lifestyle. Forget the old "eight glasses a day" rule—this tool gives you a personalized target so you can feel your best.

Staying hydrated is one of the easiest ways to improve your daily energy and focus. Every time you sweat or just go about your day, you lose fluids. This calculator takes your weight and workout routine into account to give you a clear, easy-to-follow number.

Keeping track of your water doesn't have to be complicated. With a quick check, you can figure out your ideal daily amount and grab your favorite bottle to get started. It's fast, completely private, and a great habit builder.

How to Use

1. Type your body weight in kilograms into the main box.
2. Enter how many minutes you exercise on an average day.
3. Hit calculate to run the numbers.
4. Check out your daily water goal in liters right on the screen.

Example

If you weigh 75 kg and work out for an hour, the calculator might suggest you drink around 2,800 ml of water. If you go for a long run on a hot day, you'll need even more to replace what you sweat out. Having this customized target helps you stay on track without overthinking it.

Benefits

Tips

• Keep a reusable bottle near your desk to make sipping easier.
