Have a good one

You use this phrase at the very end of a conversation. It replaces Goodbye or See you later. You usually say it as you are physically leaving. You can say it to a cashier after buying coffee. You can say it to a coworker as you walk out of the office. It sounds natural and relaxed. Just make sure you are actually leaving when you say it. Saying it and then standing there is a bit awkward!

Use it in almost any daily situation. It is perfect for service workers like waiters or bus drivers. It works great with friends you see often. Use it at the end of a phone call with your bank. Use it when you finish a quick chat with a neighbor. It is especially useful when you aren't sure if it's still morning or already afternoon. It saves you from checking your watch!

Avoid this phrase in very solemn or sad situations. Do not say it at a funeral or after someone shares bad news. It is too cheerful for those moments. Also, avoid it in extremely high-level formal settings. If you are meeting a head of state or a CEO for the first time, stick to It was a pleasure meeting you. It can also feel a bit lazy if used with a very close romantic partner. They might want something more personal than a generic one!

This phrase became a staple of American English in the 1970s and 1980s. It reflects the casual, friendly nature of Western culture. It moved from the service industry into everyday speech. It shows that the speaker wants to be polite but brief. In some cultures, goodbyes are long and complex. In English-speaking countries, we often prefer this quick, positive burst of energy. It’s about leaving the interaction on a high note.

You will hear people say Have a good'un in some rural areas or the UK. Others might say Have a great one to add more energy. Some people shorten it even further to just Have a good 'un. In Australia, you might hear Have a goodie. However, the standard Have a good one is understood everywhere from London to Los Angeles. It is a safe bet for any traveler.
