Pregnancy weight gain is a gradual and important process that reflects your baby’s development and your body’s preparation for childbirth. Many women wonder how much weight they should gain each week and whether their progress is on track.
Our Pregnancy Weight Gain Calculator is specifically designed to estimate ideal weight gain by week and trimester. It gives more detailed progress tracking compared to a general pregnancy weight tool.

Calculation Logic

0.4 kg per week after first trimester.
Expected Gain Formula:ExpectedGain=FirstTrimesterGain+(Weeksafter13×WeeklyRate)
