Unsure if you’re gaining weight too quickly or slowly, or wondering what your recommended weight gain* should be? Our Pregnancy Weight Gain Calculator tool uses your personal Body Mass Index (BMI) to help you understand what changes to expect over the entire timeline of your pregnancy.

In our Pregnancy Weight Gain Calculator, estimations are made based on the U.S. Institute of Medicine’s recommendations for weight gain in pregnancy. The table estimates recommended weight gain by week, so your actual weight gain may be slightly different from these values.


For more information, check out the CDC (Centers for Disease Control) website. If you have any questions or concerns, don’t hesitate to consult your healthcare provider.

*Recommended weight gain is only an estimate. Contact your healthcare provider to monitor your weight during pregnancy.
