Narrowbody commercial engines A CFM LEAP 1-B engine that powers the Boeing 737 MAX family costs $15 million. Similarly, the list price of the PW1100G engine that powers the Airbus A320neo is approximately $12 million.

In 2026, the cost of a new engine for an Airbus A320neo family aircraft is approximately $12 million to $15 million USD. There are two primary options: the CFM International LEAP-1A and the Pratt & Whitney PW1100G-JM (Geared Turbofan). The "sticker price" for a pair of these engines often accounts for nearly 25% to 30% of the total cost of a new $110 million aircraft. However, most airlines don't buy engines outright; they enter into "Power by the Hour" maintenance agreements where they pay a set fee per flight hour to the manufacturer. In 2026, Pratt & Whitney engines are facing a "market divergence" due to ongoing durability issues with the geared turbofan system, leading some airlines to favor the CFM LEAP engines for their higher reliability and lower near-term maintenance exposure. For an older A320ceo (classic), a used or overhauled CFM56-5 engine might cost between $3 million and $6 million on the secondary market.
