Specificity Calculator: Evaluate Test Performance Accurately

Calculate Your Test Specificity

The number of actual negatives correctly identified as negative.
The number of actual negatives incorrectly identified as positive.

Use our free Specificity Calculator to quickly determine the proportion of true negatives (TN) identified correctly by a diagnostic test or model. Understand your test's ability to avoid false positives (FP) and assess its performance in identifying individuals without the condition.

Formula:

Specificity = True Negatives / (True Negatives + False Positives)
Specificity = TN / (TN + FP)

Where:
TN = Number of True Negatives
FP = Number of False Positives
