How fast should you lose weight?

Most health authorities suggest losing about 1 to 2 pounds (0.5 to 1 kg) per week as a sustainable pace. This calculator draws a straight-line projection from your current weight to your goal at whatever steady rate you choose, so you can see the target date and the milestones along the way. If the rate you enter — or the rate a target date demands — is faster than roughly one percent of your body weight each week, the tool flags it, because very aggressive deficits are harder to sustain and more likely to cost muscle rather than fat.

Why real-world loss isn't a straight line

Actual weight loss rarely tracks a perfect line. Water weight swings from day to day, progress often slows as you get lighter (a smaller body burns fewer calories), and plateaus are normal. Treat the projected date as a planning target rather than a promise, and pair this with the Body Measurement Tracker to watch your real trend over time, or the Body Fat Calculator to check composition.

Frequently Asked Questions

How does the weight loss timeline work?
You enter your current and goal weight, then either a weekly loss rate or a target date. From the amount to lose and the rate, the calculator projects when you will reach your goal (or, from a target date, the weekly rate you would need). It assumes a steady, constant rate, so the timeline is a planning estimate rather than a guarantee.
What is a safe rate of weight loss?
A commonly recommended pace is about 1 to 2 pounds, or 0.5 to 1 kilogram, per week. This tool flags any rate faster than roughly one percent of your current body weight per week, since more aggressive deficits are harder to sustain and can cost muscle. Talk to a healthcare professional before starting an aggressive plan.
Does the calculator store my weight?
No. Everything is computed live in your browser and nothing is saved or uploaded — there is no account and no stored history. Reloading the page clears the numbers. If you want to record measurements over time, use the Body Measurement Tracker instead.
Can I switch between pounds and kilograms?
Yes. The Metric / Imperial toggle relabels the inputs and results. Because the math only compares your weights and rate in the same unit, switching units simply reinterprets the numbers you typed in the new unit rather than converting them, so re-enter values if you change units mid-way.
