The Jaccard / Tanimoto coefficient is one of the metrics used to compare the similarity and diversity of sample sets. It uses the ratio of the intersecting set to the union set as the measure of similarity. Thus it equals to zero if there are no intersecting elements and equals to one if all elements intersect.

The equation for the Jaccard / Tanimoto coefficient is
N_a – number of elements in set А
N_b – number of elements in set B
N_c – number of elements in intersecting set

How to use it – enter the elements, separated by a comma, and the calculator outputs the coefficient and intersecting set (for reference)
