Inputs assumed in thousands (000) of chosen currency unless stated.

RASM / CASM / Yield Calculator

Quickly derive key airline unit metrics. Provide traffic and financial inputs to see RASM, PRASM, Yield, CASM, break-even load factor, operating margin and contribution. Use scenario sliders to explore how changes in load factor, yield and unit cost shape performance. Interactive charts visualize unit economics, revenue mix and margin sensitivity.

Base Inputs

ASMs (000)

RPMs (000)

Passenger Revenue (USD 000)

Ancillary Revenue (000)

Cargo + Other Revenue (000)

Operating Cost (000)

Passenger Taxes (000, optional)

Ready.

Break-even load factor ≈ CASM / Yield (if Yield > 0). Per-unit metrics shown in cents of selected currency (or minor unit). All revenue & cost inputs are in thousands.

Calculated Metrics

Scenario Sliders

Sliders override correlated fields (RPM, Passenger Revenue, Operating Cost, Ancillary). Adjust to explore impact; you can still manually edit base numbers afterward.
