CASK Benchmarking Calculator

Unit cost is the single number that decides whether a route makes money. This calculator works out your CASK — cost per available seat-kilometre — and shows it against JK's competitive target and the African cost context. Runs entirely on your device.

Your inputs

All-in operating cost across the network, last 12 months.
ASK = seats × average stage length (km) × annual sectors. Don't have it precisely? Seats flown × average sector length is close enough.
Configurable. JK's competitive short/medium-haul target is ≤ 9 US¢/ASK (USD 0.09).
Approximate shares of your total operating cost — used to estimate your fuel-specific unit cost below.

CASK = total operating cost ÷ available seat-kilometres.

Context: African carriers' unit costs run close to double the rest of the world (IATA, Cost Disadvantage of African Airlines, 2025), driven by fuel (~40% of cost), thin scale and high financing and airport charges. The ≤ 9 US¢ target reflects a competitive position, not the regional average.

Indicative estimate only, for orientation. CASK is sensitive to stage length, gauge and accounting treatment, so peer comparison needs care. No data leaves your browser.
