How This Is Calculated
This calculator estimates a timeline for reaching a goal weight based on a steady weekly rate of change — useful for setting realistic expectations before you start.
The Formula
Weeks to goal = weight to change(kg) ÷ chosen weekly rate(kg/week). We then convert weeks to an approximate number of months.
Choosing a Realistic Rate
Faster rates of change are harder to sustain and more likely to affect muscle mass. A mild-to-moderate pace is generally easier to maintain long term.
A planning estimate, not a guarantee.
Actual progress varies with adherence, metabolism, and life circumstances. Use this as a rough timeline, not a fixed deadline.
