Weight Loss Calculator

This weight loss calculator will show you how long it will take to reach your target weight (gaining or losing), based on different levels of calorie intake. Determine how to lose weight fast, in few days, or a longer period of time. When selecting your activity level use:

  • Sedentary (little or no exercise)
  • Lightly active (light exercise/sports 1-3 days/week)
  • Moderatetely active (moderate exercise/sports 3-5 days/week)
  • Very active (hard exercise/sports 6-7 days a week)
  • Extremely active (very hard exercise/sports & physical job or 2x training)
The starting date is the date that you will begin your weight loss process, if that is now put in today's date, if you are starting this weekend or the beginning of the month then put in those dates. Your desired weight is the goal that you want to achieve. The calculator will then show you healthy levels of calorie changes to lose the weight, along with a goal date, the date you will reach your weight loss goal. Now you know how many calories you should eat to lose weight, this is referred to as calorie intake. Or, exercise and do activities to burn more calories, or a combination of both. If you are currently at a low level of activity and are deciding to increase the calories you burn, do that for a couple of weeks, then come back to this page and redo your numbers with your new activity level. Higher levels of activity increase your metabolism throughout the day, so basically you burn more calories the more active you are even during the times you are not exercising.

I am tracking calories in and calories burned (biking, lifting and walking). Should I use the net calorie as my base to compare with your weight loss table?

Hi! The calculated daily calorie intake (which factors in exercise) should be labeled as TDEE (total daily energy expenditure). It is currently labeled as BMR, which is inaccurate. Thanks for the calculator!

Most of the world dose not put the month first when entering dates. On Metric you should use the standard date format of dd/mm/yyyy. This would help un-confuse many of your web visitors outside of the USA (most of the world).
