Even at the undergraduate business school level, UC Berkeley Haas requires 1 full year (2 semesters) calculus for admissions. I never had to use it in my work environment. In business school, it was used to prove some complicated formula.
Many of the other competitive undergraduate business schools or business economics in the West Coast (USC, UCLA, UW) require 1 semester or 1 quarter of calculus (UCLA 2 qtrs.). The graduate business schools require the same.
