IQ Percentile Calculator – See How You Compare

Curious about where your IQ score places you among the population? Use our free IQ Percentile Calculator to find out your relative intelligence level based on your IQ test result. Discover how your score compares to the general population using standard deviation and bell curve analysis.

How It Works:
Your IQ score typically follows a bell-shaped curve, with the average set at 100 and a standard deviation of 15. This tool uses that statistical model to estimate your percentile – the percentage of people with an IQ below yours.

Instructions:

  1. Enter your IQ score.

  2. The calculator will estimate what percentile you’re in.

  3. Find out if you’re above or below average!

The bell curve above represents the normal distribution of IQ scores. The average IQ is 100, and most people fall between 85 and 115.

What Is an IQ Percentile?

An IQ percentile indicates how your IQ score compares to the rest of the population. For example, if you're in the 90th percentile, your score is higher than 90% of people. IQ scores are normally distributed, with an average (mean) of 100 and a standard deviation of 15.

How Is IQ Percentile Calculated?

IQ percentile is based on a statistical model known as the bell curve. Using your IQ score, we calculate how far you are from the mean and determine what percentage of people scored lower. This gives you a percentile rank.

What’s a “Good” IQ Score?

The average IQ is between 85 and 115. A score above 130 is considered very high and places you in the top 2%. A score below 70 may indicate a need for additional cognitive support. However, remember that IQ is just one measure of intelligence and doesn’t reflect creativity, emotional intelligence, or other important skills.

IQ Score Ranges

  • 130 and above: Very Superior
  • 120–129: Superior
  • 110–119: High Average
  • 90–109: Average
  • 80–89: Low Average
  • 70–79: Borderline
  • Below 70: Extremely Low
