Miscarriage Risk Calculator

This user-friendly calculator is designed to provide expectant parents with insights into the probability of miscarriage and the chance of a successful ongoing pregnancy, based on the gestational age.

How It Works

The calculator uses a comprehensive set of data points that indicate the probability of miscarriage for each day from 3 weeks up to 20 weeks of pregnancy. This data reflects a gradual decrease in miscarriage risk as the pregnancy progresses.

Features of the Calculator

  1. Gestational Age Calculation: By entering the due date, the calculator computes the current gestational age in weeks and days.
  2. Miscarriage Probability: It provides the percentage chance of miscarriage based on the specific gestational age.
  3. Live Birth Probability: Alongside the miscarriage risk, it also displays the probability of a successful ongoing pregnancy (live birth chance).
  4. Daily Updates: Unlike many tools that provide weekly estimates, our calculator breaks down the risk by each day, offering a more nuanced view.

Using the Calculator

  • Input the Due Date: Simply enter the due date of your pregnancy.
  • Instant Results: The calculator immediately displays your current gestational age and the corresponding probabilities.

Behind the Scenes

The calculator functions through a well-researched algorithm that assigns a specific miscarriage risk to each day of pregnancy. This risk decreases as the pregnancy progresses, reflecting medical research findings.


While our calculator is based on statistical data, it's important to remember that it is a general guide and not a medical diagnosis. Every pregnancy is unique, and we strongly advise regular consultation with healthcare providers.

Our Miscarriage Risk Calculator offers a valuable perspective for expectant parents, empowering them with knowledge about their pregnancy's progression. We believe this tool will provide reassurance and understanding during the remarkable journey of pregnancy.
