Formal:

Informal:
* चलना होगा (chalna hoga): This is a more casual way of saying "I have to go" and is commonly used with friends and family.
* मुझे जाना पड़ेगा (mujhe jaana padega): This means "I will have to go" and suggests that the speaker is reluctantly leaving.

The best translation will depend on the specific context and the relationship between the speaker and the listener.
It's also important to note that "gotta go" often implies a sense of urgency, as if the speaker has something else they need to do. When translating, you can add the word "अभी" (abhi) meaning "now" to convey this urgency, like in "अब जाना होगा" (ab jaana hoga).
