What percentage of a meteor would burn up as it passes through the Earth's atmosphere?

[Matthew]

If, hypothetically, a mile wide meteor was passing through the Earth's atmosphere, what percentage of it would actually reach the ground? I know that the meteors the size of houses are disintegrated to small rocks, which would mean that more than 90% of the meteor would disintegrate, but does the percentage decrease substantially as the size increases? The Chickxulub Crater, the one that is believed to wipe out the dinosaurs is approximately 110 miles in diamter. But I've researched that the the size of the meteor is generally one twentieth of the size of the crater due to the force and speed of the meteor at impact. If that is true, that would mean that the meteor is approximately 5.5 miles in diameter. But what would the size be as it travels in space? I'm just curious because I am in the process of writing a trilogy.

Thanks to everyone who takes the time out to answer my question.
