Break Even Load Factor Calculator

Break-even load factor is the percentage of airline seat capacity that must be sold for passenger revenue to cover operating cost.

Formula: BELF = Cost per ASM / Yield per RPM

CASM (cost per ASM)Yield (revenue per RPM)

If CASM is $0.08 and yield is $0.11, BELF is 72.7%. Airlines then compare this against forecast load factor.
