Miscarriage Rates by Week Calculator



Facing a miscarriage is a challenging and emotional experience for many individuals. Understanding the likelihood of miscarriage at different weeks of pregnancy can provide valuable information and support. The Miscarriage Rates by Week Calculator serves as a tool to estimate the risk of miscarriage during various stages of pregnancy, offering insights for those navigating this sensitive journey.


The formula for calculating miscarriage rates is typically based on statistical data. It considers the number of reported miscarriages at a specific week divided by the total number of pregnancies during that period. The formula is:

Miscarriage Rate=Number of Miscarriages at a Specific Week Total Number of Pregnancies at that Week×100

It’s essential to note that individual circumstances can vary, and this calculator provides general statistical information.

How to Use?

  1. Enter Gestational Week: Input the specific gestational week you want to calculate the miscarriage rate for.
  2. Retrieve Data: Access reliable data sources or consult medical literature to obtain the number of reported miscarriages and total pregnancies for the chosen week.
  3. Apply the Formula: Utilize the formula to calculate the miscarriage rate for the selected week.


Let’s consider an example:

  • Gestational Week: 8
  • Number of Miscarriages at Week 8: 20
  • Total Pregnancies at Week 8: 500

Miscarriage Rate=20500×100=4%

So, the estimated miscarriage rate at week 8 is 4%.
