The main difference between 'How are you?', 'How's it going?', and 'What's up?' lies in their level of formality. 'How are you?' is the most versatile and can be used in formal situations, 'How's it going?' is a friendly and casual alternative, while 'What's up?' is a very informal slang greeting used between close friends.
Navigating common English greetings can feel like a minefield for beginners. You hear native speakers use these phrases interchangeably, but are they really the same? Understanding the subtle social rules behind each one is key to sounding natural and confident. This guide will explain the real difference between 'How are you?', 'How's it going?', and 'What's up?' so you can use each one perfectly.
What's the Real Difference Between 'How are you?', 'How's it going?', and 'What's up?'
While all three phrases are used to ask about someone's well-being or current state, their usage depends entirely on the context and your relationship with the person you are speaking to. Think of it as a spectrum from formal to very casual.
When Should I Use 'How are you?'?
'How are you?' is your safest and most versatile option. It's a standard, polite English greeting that fits almost any situation.
- Formality: Neutral to Formal.
- Who to Use It With: Anyone! This includes your boss, a new acquaintance, a shopkeeper, a doctor, an older person, or a friend.
- Typical Context: Professional settings (job interviews, meetings), formal events, or when meeting someone for the first time.
- Expected Answer: This question usually expects a short, polite answer. Most of the time, it's a form of 'hello' rather than a genuine inquiry into your life's details.
- Example 1 (Formal): In an office, you might say, "Good morning, Mr. Davis. How are you today?"
- Example 2 (Polite): To a cashier at the supermarket, you could say, "Hello, how are you?"
When is 'How's it going?' a Better Choice?
'How's it going?' is a step down in formality. It’s warmer and more relaxed than 'How are you?' and is extremely common in everyday conversation.
- Formality: Casual / Informal.
- Who to Use It With: Friends, colleagues you know well, classmates, and family.
- Typical Context: Relaxed social situations, like bumping into a friend at a coffee shop or starting a conversation with a coworker in the break room.
- Expected Answer: The response is still usually brief but can be slightly more personal than the reply to 'How are you?'.
- Example 1: Seeing a friend on the street: "Hey, Sarah! How's it going?"
- Example 2: To a classmate before class: "Hi, Tom. How's it going? Did you finish the homework?"
What Does 'What's up?' Really Mean?
'What's up?' is the most informal and casual of the three. It's often used less as a question and more as a simple acknowledgment or 'hello' among peers.
- Formality: Very Informal / Slang.
- Who to Use It With: Close friends, siblings, and peers in a very relaxed setting. Avoid using it with figures of authority or people you don't know well.
- Typical Context: Texting a friend, answering a call from a buddy, or meeting up with your social group.
- Expected Answer: The answer is often not about how you *feel*, but what you are *doing*. It's also very common to respond with 'What's up?' back.
- Example 1: Greeting a friend: "Yo, what's up?" Response: "Not much, just chilling. What's up with you?"
- Example 2: Answering the phone: "Hey, what's up?"

Frequently Asked Questions (FAQ)
Can I use 'what's up' in a formal email?
Absolutely not. 'What's up' is extremely informal slang and would be considered unprofessional and inappropriate in any formal communication, especially writing. Stick to 'How are you?' or simply begin with your main point.
Is 'how's it going' rude to say to a stranger?
It's not necessarily rude, but it can be seen as overly familiar. If you are speaking to an older person, a person in a position of authority, or a customer in a service role, 'How are you?' is the more polite and appropriate choice.
What is a good reply to 'How are you?' if I'm not feeling good?
While the standard response is positive, you can be honest without giving too much detail. Polite options include, "I've been better," or "A little under the weather, but I'll be okay." With close friends, you can be more direct.
Do native speakers always expect a real answer to these questions?
Most of the time, no. 'How are you?' and 'How's it going?' often function as a social ritual or a way of saying hello. A short, simple response is the norm. Only close friends or family are typically looking for a detailed, honest answer.
What's another formal way to say 'How are you?'
If you haven't seen someone in a while, a great formal or semi-formal alternative is "How have you been?". This invites a slightly more detailed answer about what has happened since you last met. For a general alternative, "How are things?" works well.
