Key points
Use these in casual speech or self-talk to say that something has to be done, with the sense that not doing it would cause a problem. They are conversational: in polite or formal situations use ないといけません / なければなりません. なきゃ is a casual contraction of なければ, while なくちゃ is a casual contraction of なくては. The omitted ending can also be included, e.g. 行かなきゃいけない. These expressions are not used for prohibitions. In ないと, と retains its conditional meaning ('if'), but the negative consequence is left unstated, creating the sense of obligation.
