CALORIE CALCULATOR
← Tools
The Calorie Calculator can be used to estimate the number of calories a person needs to consume each day. This calculator can also provide some simple guidelines for gaining, maintaining or losing weight.

Note: These calculations are based on averages using the Harris-Benedict formula. They are appropriate for healthy, non-pregnant adults 18 and older. Consult with your physician or other health care professional before starting any new eating program to determine if it is right for your needs.

We do not recommend eating below 1000 calories if you are a woman or eating below 1500 calories if you are a man.
