Topple rate is a name of a ratio of speed at which firms lose their leadership positions. It was believed that it was originally created by Jack Percival following losing his job. The Wall Street Journal article that appeared on September 9, 2007 attributes authorship to Patrick Viguerie, a McKinsey & Co. consultant.

For example, the minicomputer industry began, grew up, got big, profitable, smug, senile and died in 20 years from 1975 to 1995. Digital Equipment Corporation is a prime exemplar. In this case the topple rate of the minicomputer industry was 20 years.

A high topple rate is especially frequently used as a saying in fields of technological business.
