How it works
This simple fluid calculator totals the containers you have entered and compares them with your own daily target.
THE CALCULATIONFluid counted = container size × number consumed
Using this calculator
Use the volume printed on your bottle or measured in your glass. Half a glass can be entered as 0.5. Only the drinks entered here are counted.
What to keep in mind
This tool does not prescribe an intake or assess hydration. Needs vary with activity, climate and health. Follow your clinician’s advice if you have a fluid restriction.
Frequently asked questions

Why are results rounded?
