Estimate kilograms and percent change from a start weight to a current weight.
| Change | – |
| Change (%) | – |
Use this calculator for change = now − start and percent = 100 × (now − start) ÷ start. A negative result is loss. BMI-weight-loss clones that only wrap this ratio are merged here. This is not a body-composition scan.
Start and current weight can be entered in kilograms (kg) or pounds (lb); the calculator converts both to kilograms before the formula. The kilogram change is shown in kg or lb.
Start: Weight at the start of the period, in kg or lb.
Now: Weight now, in kg or lb.
Change: Absolute change, now minus start.
Change (%): Percent change from start.
