AppleCare+ (similar for iPhone and iPad, each incident of accidental damage) for Mac will carry its own price tag. Screen damage or “external enclosure damage” will run $99 per incident, while other damage, including water damage, will run $299. Users receive coverage of two incidents under AppleCare+, and after the two incidents have been used up, out-of-warranty replacement rates will apply

Probably more than the keyboard, most likely the entire logic board. Leave it off, drain liquid out but do not try to dry it out with rice.

If your system is 2012 or 2011, you can remove the SSD or HD to extract data from the drive later. But be sure you know where your backups are.

Call 1-800-MY-APPLE to find out how to send it in for review. Cost depends on actual damage.
