Is 400 ms a good number reaction time?
A 400 ms number reaction time lands squarely in the Fast tier — meaningfully above the typical adult. You are in the top quartile of test-takers and ahead of most people on their first attempt. 400 ms is one of the round-number search references queried about number reaction time scores. Against the standard benchmarks, your 400 ms score is 100 ms past the Elite cutoff (300 ms), 50 ms ahead of the Fast cutoff (450 ms), and 200 ms ahead of the Average cutoff (600 ms). The neighboring indexed buckets are 300 ms (Elite) and 450 ms (Fast). Take the Number Reaction Test to see how your live performance compares.

Frequently asked questions
Is 400 ms a good number reaction time?
Yes — 400 ms is in the Fast tier, comfortably above the average band (600 ms). Most untrained adults would not hit this on a typical attempt.
How does 400 ms compare to the average?
The Average threshold on the Number Reaction Test is 600 ms. Your 400 ms is in the Fast band relative to that. Elite performers cross 300 ms; Fast performers cross 450 ms.
How can someone push past 400 ms?
Consistent practice — same environment, same time of day, same input device — is the biggest lever. Take the Number Reaction Test a few times per week, sleep well, and watch how your score drifts toward the Fast (450 ms) and Elite (300 ms) thresholds over a few weeks.
