The Boeing 747-400 is one of commercial aviation’s most recognized aircraft, as it is an icon that, as of 2026, sits at the intersection of nostalgia, hard economics, and a surprisingly complex secondhand market. If one is interested in answering the question of how much a 747-400 costs, one will get bogged down in different side cases, struggling to find a clean number. There is no current new aircraft price tag to help anchor expectations, and every airframe has pretty much lived a long and unique individual life. Jets have traveled across various operators, endured different types of maintenance, and have distinct engine histories. Everything from different storage conditions to mission histories can vary significantly and have a significant impact on the actual secondary retail value of the jet. In practice, the cost of aBoeing 747-400 is actually a bundle of prices, starting with the headline acquisition figure, which the buyer will need to pay directly for the aircraft itself.
