Check the color
Look at the avocado's color. Avocados that aren't yet ripe are pale to dark green. Ripe avocados are dark green to greenish-brown, and an avocado that is dark brown to black is rotten.
Pull out the stem
Determine if an avocado is rotten by prying the stem from the top of the avocado. If the bottom of the stem is mushy, black, or mildewed, the avocado is probably rotten.
Feel the avocado
Pick up the avocado. If it is hard and unyielding, it isn't ripe yet. If it's overly soft and mushy, it's rotten.
Cut it open
Cut open the avocado with a knife. If it's dark green near the skin and pale green near the stone, it's ripe. But if the meat is separated, stringy, and brown or black, it's rotten. If the meat of a ripe avocado is exposed to air, it'll brown quickly, but you can skim off the top layer and still use the avocado.
