Weight Loss Calculator


This weight loss calculator is a great way to determine your daily calorie needs in order to lose the weight you want and reach your ideal weight.

This tool not only gives a recommended calorie intake, it is a goal calculator.

What this means is that it will estimate how long it will take you to lose the weight based on your activity level. Use the guide below when selecting the activity level.

How to Use the Calculator

To use the calculator, select your gender, enter age, current weight, goal weight, height and activity level. Click on calculate to find out how many calories to consume daily for maintaining weight, losing 1 pound a week or a 2 lb a week weight loss. Scroll down the page for help on determining your activity level.

This weight loss tool will not go below a 1,000 a day calorie diet recommendation. If the recommendation falls below this number, you will receive a caution instead of the calorie needs.

It estimates the time based on a 1 or 2 pound a week loss, not any more than that, as this is a sustainable weight loss goal. If you are determined to lose weight, and keep it off, then you want to do it at a pace that will allow you to keep it off for life.

Remember to come back to this page often as you lose weight and estimate how much longer it will take to reach your goal. Your calorie budget will change as your weight changes so be sure you are adjusting as you lose weight.

Activity Level Guide

Use the below information to determine your activity level to get the proper calorie needs for your weight loss goals.


A sedentary activity means little or no exercise in your daily routine. A person living a sedentary lifestyle is often sitting or lying down while engaged in an activity like working at a desk, reading, watching television and more. If this sounds like you and you get little to no exercises in your typical day, then select sedentary in the weight loss calculator.

Somewhat Active

Select "somewhat active" if your lifestyle includes light exercise one to three days a week. Light exercise might be a walk around the block with a friend, cleaning house, or low intense workouts. The rule of thumb is if you can sing a song while doing your workout, then this would be considered a light exercise.

Moderately Active

Use this selection if you do moderate exercise or sports three to five days a week. A moderate workout would be an exercise that quickens your breath, but you are not out of breath. You can carry on a conversation, but you would not be able to sing a song. The last way to tell is you would start to break out in a light sweat after about 10 minutes into your exercise.

Very Active

This selection would be used if you do hard exercise or sports six to seven days a week. You know you are doing an active workout if you start to break out in a sweat in just a few minutes. Talking will be difficult you will be breathing rapidly. These activities would include hiking, biking, swimming laps and jogging to name a few.

Extremely Active

An extremely active lifestyle would be if you did hard daily exercise or sports plus physical job or exercise two times a day. So if you do intense workouts once (or even twice) a day plus have a physical job, this is the category you would fall into for the weight loss calculator above.
