What is this calculator?
If the scales moved at a steady weekly pace, this tool sketches a calendar date. Real life is bumpier.

- We add the weeks onto today's date.
Common questions
What is the target weight date calculator?
It estimates when you might hit a goal if the weekly change stays constant.
Why 0.5 kg a week?
It is a common adult planning pace. Faster cuts are harder to keep and can be unwise.
What if I stall?
Recalculate. Sleep, stress and weekends often explain a pause.
Example scenarios
Marcus, slower cut
95 to 90 kg at 0.3 kg a week
About 17 weeks.
Jo, regain plan
52 to 57 kg at 0.25 kg a week
About 20 weeks.
Understanding your results
Treat the date as a sketch. If the pace feels grim, slow it down. A later date with a life you can keep is the better trade.
