Pregnancy Weight Gain Calculator

The Pregnancy Weight Gain Calculator will help you determine the recommended weight gain that will promote a healthy pregnancy.

What are the benefits of gaining a healthy amount of weight during pregnancy?

Gaining a healthy amount of weight during pregnancy can:

  • help your baby have a healthy start;
  • reduce your risk of complications in pregnancy and at delivery; and
  • improve your long-term health.

Recommended weight gain is based on a woman's Body Mass Index before pregnancy (her pre-pregnancy BMI).
