How do you say 'i am good' in German?

Answer 1

If you mean "Good" in the sense of "healthy" then it is "Ich fuehle mich gut" or "Mir geht es gut". If you mean good in the sense of "not bad/evil" it is "Ich bin gut"

Answer 2

"Ich bin gut."

If you are referring to the reply you give after someone asks "How are you?" (wie geht es Dir?) then the translation is mir geht's gut
