Yes, but the fact that the Me-262 could own almost anything that was thrown at it certainly makes it worth the cost. And I'm not just on about speed. The book "Luftwaffe" (I forgot who wrote it) has graphs that show that the 262 had greater firepower then any other fighter plane shown. Including Mustangs, Me-109s, Spitfires, Hurricanes, etc.

The sheer amount of planes that Me-262s shot down, when heavily outnumbered, in the last year of war, shows that the Me-262 was worth almost any cost.
