The mean plasma elimination half-life of Xanax is reported to be 11.2 hours. The full range is from 6.3 to 26.9 hours in healthy adults.

For a drug to be totally eliminated from your system it takes 5.5 times the half life.

If we take the maximum time of 26.9 hours times 5.5, it will be in your system for approximately 148 hours i.e. 6 days, after your final dose.

It depends on a variety of factors. Suzanne's answer is accurate for healthy adults. You can always add 12-18 hours to that. Hope this helps.
