GE9X price, GE90 value, Trent XWB cost, LEAP, CFM56 — and what drives engine asset values for lessors, MROs, and investors
Top 10 Most Valuable Aircraft Engines — 2026
Aircraft engines are among the most valuable assets in commercial aviation. A single powerplant can cost more than a private jet, and in today's market, some engine types are worth more than the aircraft they power. With sustained MRO backlogs, supply chain constraints, and delayed new aircraft production, engine values and lease rates have remained elevated across the market.
This ranking of the top 10 most valuable aircraft engines in service is based on current market values, lease rates, and strategic importance to the global fleet. Data is drawn from IBA's Engine Value and Lease Rate Update (H1 2026), industry reports, and manufacturer announcements.
Methodology: How We Ranked the Most Valuable Engines
Ranking aircraft engines by value requires a multi-dimensional approach. Our methodology is based on the following criteria:
Ranking Criteria
- Full-Life Market Value: The estimated market value of a serviceable engine with full remaining life
- Half-Life / Mid-Life Value: Market value with approximately 50% of life remaining
- Lease Rates: Current monthly spot lease rates for serviceable engines
- Installed Fleet Size: Number of aircraft currently powered by the engine type
- Market Demand: Current demand relative to available supply
- MRO Economics: Cost and complexity of maintenance, overhaul intervals, and LLP replacement
- OEM Support: Availability of parts, technical support, and future production plans
Values are indicative and reflect the commercial engine market as of mid-2026. Military engines are excluded from this ranking, as they serve a distinct market with different valuation dynamics.
The Ranking: Most Valuable Aircraft Engines in 2026
General Electric GE9X
The GE9X is the world's largest and most powerful commercial jet engine, with a front fan diameter of 134 inches — larger than a Boeing 737 fuselage. Its list price of $42–45 million per engine exceeds the list price of many private jets. With 4,000+ hours of flight testing, the GE9X is set to enter service on the Boeing 777X with Lufthansa as the launch operator. The engine's value is underpinned by its exclusivity, advanced technology, and the 777X program's strategic importance.
General Electric GE90-115BL
The GE90-115BL powers the Boeing 777-300ER and has seen extraordinary value growth. Full-Life values have surpassed $32 million, with Half-Life Market Values increasing by 60% since 2023. Serviceable engines trade above $20 million, and long-term lease extensions are being observed at spot lease rates of $170,000–$185,000 per month. The GE90's value is underpinned by constrained widebody production and ongoing delays to the 777X program. Source: IBA Engine Value and Lease Rate Update, H1 2026.
Rolls-Royce Trent XWB
The Trent XWB is the exclusive engine for the Airbus A350 family and one of the most efficient large turbofans in service. Valued at approximately $25 million per unit, its worth reflects its advanced materials, 70% composite airframe integration, and the A350's strong market position. With over 1,400 A350 orders, the Trent XWB remains a highly strategic and valuable engine program.
General Electric GEnx-2B
The GEnx-2B powers the Boeing 747-8 and offers 15% better fuel efficiency than legacy 747-400 engines. New engines list at $25–30 million, while mid-life used examples trade at $12–18 million. The 747-8's role as a cargo specialist, combined with the engine's efficiency advantage, has helped maintain its value despite the 747's phase-out from passenger service.
Rolls-Royce Trent 700
The Trent 700 has seen the sharpest value increases in the A330ceo market, with overhauled examples now reaching $18 million. The engine benefits from a large installed base and a significant MRO backlog. Rolls-Royce has expanded its MRO network, including a new joint venture facility in China (BASEL) and a partnership with Sanad Aerotech, to support the growing fleet.
CFM International LEAP-1A / -1B
The LEAP engine family has been the most successful new product introduction in CFM's 50-year history, surpassing 70 million flight hours in nine years. It delivers 15% better fuel efficiency and 15% lower CO₂ emissions than the CFM56, with 99.95% departure reliability. However, the LEAP has faced durability challenges, including fuel nozzle carbonisation and accelerated wear in harsh operating environments. As more engines reach maturity, the availability of used serviceable materials (USM) is expected to ease cost pressures. Source: CFM International.
IAE V2500-A5
The V2500-A5 remains in strong demand, with Non-Select examples trading between $11 million and $13 million for engines fresh from overhaul including new Life Limited Part replacements. The engine's uniform 20,000-cycle LLP limit requires larger shop visit scopes rather than modular repairs, pushing demand for engines with decent life remaining. A shortage of available Select engines further keeps Non-Select values inflated. Source: IBA Engine Value and Lease Rate Update, H1 2026.
Pratt & Whitney PW1100G (GTF)
The PW1100G Geared Turbofan is the most sought-after engine in the narrowbody market due to a perfect storm of demand and scarcity. A 2023 manufacturing defect triggered widespread inspections and grounded over 600 A320neo-family aircraft worldwide. Working GTF engines are now so scarce that a pair can be leased for about $400,000 a month — often more than leasing the entire aircraft. Pratt & Whitney reports improving material readiness and is introducing the GTF Advantage engine from mid-2026, along with a Hot Section+ package. Source: Business Insider Africa, May 2026.
CFM56-5B / -7B
The CFM56 is the gold standard for time-on-wing reliability, with many engines flying over 14,000 hours and 10,000 flights before a first shop visit, and some approaching 30,000 hours. Values have levelled off after 18 months of increases, indicating the market may be reaching a plateau. Demand for serviceable engines remains high, particularly where operators are seeking to avoid costly and time-intensive maintenance events. Source: CFM International.
Rolls-Royce Trent 1000
The Trent 1000 powers the Boeing 787 Dreamliner and has been a significant value driver for Rolls-Royce. Following years of durability challenges and MRO backlogs, the engine has stabilised with enhanced design upgrades. Its value is supported by the 787's strong market position, with over 1,900 deliveries and a substantial backlog. The engine's lease rates and values are recovering as MRO capacity expands and reliability improves.

What Determines Aircraft Engine Value?
For aviation finance professionals, lessors, and investors, understanding the drivers of engine value is essential. Key factors include:
Key Value Drivers
- Remaining LLP Life: Life-Limited Parts (LLPs) such as turbine disks and fan blades have finite cycles. Engines with more remaining LLP life command higher values
- Time Since Overhaul: Engines fresh from overhaul (or "green time") are significantly more valuable than those approaching their next shop visit
- Engine Configuration: Select vs. Non-Select, thrust rating, and specific options affect market value
- MRO Status: Maintenance history, compliance with ADs/SBs, and service bulletin incorporation
- Fleet Demand: The number of aircraft in service and projected demand for the engine type
- USM Availability: Used Serviceable Material availability affects new part demand and engine values
- OEM Support: Availability of parts, technical support, and future production plans
- Emissions Compliance: Compliance with current and future emissions regulations (e.g., ICAO, EASA)
The GE90 market illustrates these dynamics perfectly. With constrained widebody production and delays to the 777X, GE90-115BL Full-Life values have surged past $32 million — a 60% increase since 2023.
