Goal timeline calculator
“How long will it take?” deserves a real answer — a date on the calendar, not a shrug. Enter where you are, where you’re going, and the weekly pace you can live with, and this calculator gives you the date you arrive.

I can put a calendar date on your goal weight. Three things — where you are, where you're going, and how fast you want to move.

First — pounds and inches, or kilos and centimeters?
Common questions
- What's a sustainable rate of weight change?
- A common working range is 0.5% to 1% of your bodyweight per week for fat loss, and considerably slower for muscle gain. This calculator flags anything above 1% per week — faster is possible, but it gets harder to hold and more of the loss tends to be muscle.
- Will I actually lose weight at a steady rate?
- Rarely. Real progress comes in stretches and stalls — water shifts, plateaus, life. The date here assumes your average weekly rate holds, so treat it as a realistic midpoint, not a promise.
- Why does the calculator warn me about my rate?
- Because the rate is the part people get wrong. An aggressive rate makes the date look great and the diet unlivable. The warning fires when your chosen rate exceeds 1% of your bodyweight per week.
