Weight Loss Timeline Calculator

See how long it will take to reach your goal weight and the daily calorie deficit you'll need to get there. Free, instant, no signup.

How the timeline works

Roughly 3,500 calories equals one pound of fat, so a 500-calorie daily deficit yields about a pound a week. Your real rate will vary as your weight and metabolism change, so treat the date as a motivating target, not a guarantee.

Hit the deficit without guessing

A timeline only works if you actually hit the daily deficit — and that means knowing what you eat. MyDietJourney estimates the calories in your meals from a photo, so you can stay on pace without weighing food or logging by hand.
