What Is a Chance of Miscarriage Calculator?
A Chance of Miscarriage Calculator is an online risk estimation tool that evaluates pregnancy-related factors and provides an approximate miscarriage risk level.
It uses four main inputs:

How to Use the Chance of Miscarriage Calculator
Using this tool is simple and takes only a few seconds. Follow the steps below:
Step 1: Enter Mother’s Age
Input the age of the pregnant woman in years.
- Younger age (below 25) may show slightly lower risk
- Higher age (35+) may show increased risk
Step 2: Enter Pregnancy Weeks
Add the current stage of pregnancy in weeks.
- Early pregnancy (6–12 weeks) is considered more sensitive
- Later stages show comparatively lower risk impact
Step 3: Select Previous Miscarriage History
Choose whether there has been a previous miscarriage:
- Yes → increases calculated risk
- No → keeps risk lower
Step 4: Select Smoking Habit
Choose smoking status:
- Yes → increases risk score
- No → keeps risk stable
Step 5: Click “Calculate”
The tool will instantly display:
- Estimated miscarriage risk (%)
- Risk level (Low / Moderate / High)
Step 6: Review and Understand Results
Use the result for awareness only. If risk appears moderate or high, it is advisable to consult a healthcare professional.
How the Risk Is Estimated
The calculator evaluates multiple contributing factors:
Age Factor
- Below 25 → slightly lower risk
- 35–39 → increased risk
- 40+ → higher risk
Pregnancy Stage Factor
- 6–12 weeks → higher sensitivity period
- 13–20 weeks → moderate influence
- Beyond 20 weeks → lower influence
Medical History
A previous miscarriage increases risk weight in the calculation.
Smoking Habits
Smoking adds additional risk due to reduced oxygen supply and other health impacts.
The final result is categorized into:
- Low Risk (<15%)
- Moderate Risk (15–29%)
- High Risk (30%+)
