About this calculator

This calculator estimates a healthy total weight gain range during pregnancy using the Institute of Medicine (IOM) guidelines, which set different recommended ranges depending on your pre-pregnancy BMI category — underweight, normal weight, overweight or obese.

Expecting mothers and the obstetric providers and midwives who monitor them use these ranges as a general guide, since gaining too little or too much has been linked to different pregnancy risks. Enter your height, pre-pregnancy weight and current week to see your BMI category, target range, and roughly how much you should have gained by now.
