How accurate is this IQ calculator by age?

This calculator provides an estimate based on the standard IQ formula (Mental Age / Chronological Age × 100). For a precise IQ assessment, consult a licensed psychologist who can administer a comprehensive intelligence test.

What is considered an average IQ score?

The average IQ score is 100, with most people (about 68%) scoring between 85 and 115. Scores above 130 are considered gifted, while scores below 70 may indicate intellectual disability.

Can I use this calculator for children?

Yes, the calculator works for all ages. For children, the mental age concept in the IQ formula is particularly relevant as it compares a child's cognitive development to their chronological age.

Does IQ change with age?

While IQ scores tend to remain relatively stable throughout adulthood, they can fluctuate slightly. Crystallized intelligence (knowledge and skills) often increases with age, while fluid intelligence (problem-solving) may decline slightly.
