Calculator guide
How this calculator works
How to use this calculator
Enter your current weight, target weight, and expected weekly weight change. The calculator estimates how many weeks it may take and the target date.
Formula used
Weeks to Target = |Current Weight − Target Weight| ÷ Weekly Weight Change. Target Date = Today + Estimated Days.
Example calculation
If current weight is 80, target weight is 72, and expected weekly change is 0.5, the estimated time is 16 weeks.
What the result means
The result is a simple timeline estimate. Real weight change is rarely perfectly linear.

Yes. It works whether the target weight is higher or lower than the current weight.
