Comprehensive Calculator Guide
This calculator shows how much weight you have lost, in kilograms and as a percentage of your starting weight. Going from 95 kg to 88 kg is a loss of 7 kg, or 7.4%. Percentages compare progress fairly between people and are what health guidance uses when describing benefits.
Why a percentage, and a sensible pace
Losing 7 kg from 95 kg is 7.4%, but from 60 kg it is 11.7%. Health guidance notes that losing 5–10% of body weight can improve blood pressure, blood sugar and cholesterol in people with excess weight.
A commonly recommended pace is about 0.5–1 kg a week. Weight swings from day to day with water and salt, so compare weekly averages.
