Unsure what the average weight gain during pregnancy is, or 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. 

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

First, enter your information (pre-pregnancy weight and height) into the calculator. You’ll also need to indicate if you are expecting twins as this affects the estimations. Weight gain estimations are then calculated for you. You can refer to the handy prediction table to view the recommended weight gain for every week of your pregnancy or hit recalculate to start again. It’s that simple!

Our Pregnancy Weight Gain Calculator tool takes into account your personal Body Mass Index (BMI) when making estimates. BMI is a measure that considers a person’s weight and height to determine if a person’s weight is healthy. BMI is not an indicator of someone’s health status, but it can be used by healthcare providers to help anticipate if someone’s weight will have an impact on their health.

The CDC recommends that pregnant women should track their weight at the beginning and regularly throughout their pregnancy. By comparing your progress to the recommended ranges of healthy weight gain you can stay informed and reassured that you’re on the right track.


Setting appropriate goals for weight gain and tracking your progress should always be done in consultation with your healthcare provider throughout your pregnancy, but the Pregnancy Weight Gain Calculator tool is an extra way to follow your progress week by week and in the comfort of your own home.

The Pregnancy Weight Gain Calculator is a useful guide to help you track your personal weight gain journey and reach an appropriate weight gain within a recommended range. Your results are generated based on the recommended weight gain during pregnancy, per week, for your pre-pregnancy BMI.


Each and every mom-to-be is unique, and there are always many factors to consider when looking at the rate and amount of weight gain during pregnancy. Your healthcare provider will keep a close eye on your overall health, including the amount of weight you gain, and is your best resource for advice and support.

Gaining the recommended amount of weight during pregnancy can support your baby’s well-being and healthy growth. A healthy pregnancy weight gain range is calculated using your pre-pregnancy body mass index (BMI). It is an estimated range of weight gain, with upper and lower limits, to suggest what a healthy weight gain might look like along your pregnancy.


The Pregnancy Weight Gain Calculator is a great way to track your progress in pregnancy, but you should regularly consult your healthcare provider to discuss, monitor, and support your pregnancy weight gain goals.

Falling within a recommended weight gain range helps keep you and your baby healthy and may reduce the risk of complications during your pregnancy and after. If you are falling outside of the weight gain estimation range, you can discuss this with your healthcare provider, since this might be normal for you and your pregnancy. There is often lots that can be done to support your weight gain goals, such as maintaining a healthy pregnancy diet and exercising during pregnancy, so be sure to consult with your provider.
