What Is an IQ Calculator?
An IQ Calculator estimates Intelligence Quotient (IQ) using the standard formula:
IQ = (Mental Age ÷ Chronological Age) × 100
It measures how a person’s intellectual performance compares to their actual age.
Required Inputs
1. Chronological Age
Your actual age in years.
2. Mental Age
The age level at which you perform intellectually, typically determined by standardized testing.
Calculation Formula
IQ = (Mental Age / Chronological Age) × 100
Example:
- Mental Age: 12
- Chronological Age: 10
IQ = (12 ÷ 10) × 100 = 120

IQ Score Interpretation

Practical Example
If a 15-year-old performs at an 18-year-old level:
IQ = (18 ÷ 15) × 100 = 120
This places the individual in the superior range.
