Throughout Mexico, Wilma's damage was estimated at $4.8 billion (MXN, US$454 million), mostly in Quintana Roo, where it was the state's costliest natural disaster. The hurricane resulted in $13.9 billion (US$1.3 billion) in lost economic output and earnings, 95% of which was related to lost tourism revenue.
