Ways to Say

60+ Ways to Say Good Luck With 200+ Example Sentences

"Good luck" is said before an event, never after it, and it fits any person at any level. That is why the other ways to say good luck matter: each one adds warmth, confidence, or humour that the two plain words do not have. "Break a leg" belongs to the stage, "you’ve got this" belongs to a friend, and "I wish you every success" belongs to a formal email. The everyday wishes come first.

These six wishes fit a neighbour, a classmate, a colleague, or a stranger, and each one works in speech and in writing.

  • I applied this morning, so fingers crossed!

Say "good luck" when the person has work to do and "fingers crossed" when the result depends on someone else.

Casual Ways to Say Good Luck to Friends

Casual wishes are for close friends and family, and each one sounds like a push of confidence rather than a polite formula.

You’ve got this: the most common friendly wish today, and it means "you are ready, so go and do it". It fits a text, a hug at the door, or a call the night before.

  • Go get ’em, tiger!
  • Big game tonight? Go get ’em.

Formal Ways to Say Good Luck at Work

Formal wishes fit a manager, a client, a candidate, or a colleague you do not joke with, and each one names success rather than luck.

The one casual wish that reaches formal emails by mistake is "knock ’em dead".

  • Knock ’em dead at the board meeting, Ms Adams. ❌

"Knock ’em dead" is slang for a stage or a pub, so a senior colleague gets "best of luck" with the name of the event.

  • Best of luck at the board meeting, Ms Adams. ✅

Ways to Say Good Luck in an Email

In an email the wish names the event, and it goes in the last line before the sign-off.

Good luck with the launch: the standard email wish for a colleague, and the noun after "with" changes with the event: the launch, the audit, the exam, the move.

  • Good luck with the launch on Tuesday, the whole team has worked hard for it.
  • Good luck with the exam, Ravi, and enjoy the break afterwards.

  • I hope everything goes smoothly with the handover on Friday.
  • I hope everything goes smoothly at the hospital next week.
  • I hope everything goes smoothly, and please shout if you need anything from us.

  • Good luck on Thursday, and let me know how it goes.
  • Best of luck with the interview, let me know how it goes!
  • Fingers crossed for the results, let me know how it goes.

Put "good luck with" plus the event in the last line of the email, and add "let me know how it goes" when you want a reply.

Ways to Say Good Luck in a Card

A card wish is kept and read again, so it is longer than a spoken wish and it names the future.

  • Wishing you the best of luck in your exams, love from Gran.
  • Wishing you the best of luck on the big day.

"Best wishes" also fits a card, and it has a page of its own, so this page keeps to the luck wishes.

Write "wishing you the best of luck" at the top of a card and add one line about the person under it.

Ways to Say Good Luck in a Text

A text wish is short, and exclamation marks and capital letters do the work of your voice.

Good luck!!: the plain wish with two marks, and the extra mark makes it warm instead of flat. Three marks read as shouting with joy.

  • Good luck!! You’re going to be brilliant.
  • Good luck!! Text me after.
  • Saw your post, good luck!!

GL: the two-letter form of "good luck", common in gaming chats and quick messages between friends. Keep it out of any message a teacher or a manager will read.

  • GL on the boss fight, I’m off to bed.
  • GL tomorrow, don’t stay up too late!

Keep a text wish under six words, and let the exclamation mark do the warmth.

Ways to Say Good Luck Before an Exam

An exam wish names the test, and each one either wishes luck or asks for effort.

Good luck on your exam: the American form, and British English says "good luck in your exam". Both are correct, so match the person you are speaking to.

  • Good luck on your exam tomorrow, Ethan, get some sleep.

  • Ace it, Lily, then we’re going for ice cream.
  • You’ll ace it, you always do.
  • Go and ace it, and stop worrying.

Nail it: slang for "do it perfectly", used for an exam, a driving test, or a speech.

  • Nail it tomorrow, Ben, you know this stuff.
  • I know you’ll nail it.
  • Nail it, and then sleep for a week.

Do your best: a wish that asks for effort rather than a top mark, and it fits a parent or a teacher who wants to take the pressure off.

  • Do your best, Hana, that’s all anyone can ask.
  • Just do your best and read every question twice.
  • Do your best tomorrow, and we’ll talk about the rest later.

Say "good luck on your exam" in American English, "good luck in your exam" in British English, and "do your best" when the person is nervous.

Ways to Say Good Luck Before an Interview

An interview wish gives confidence, and it goes in a text the night before or a call in the morning.

Good luck with the interview: the neutral wish, and it fits a colleague, a friend, or a family member. "Good luck at the interview" is also correct.

  • Good luck with the interview, Priya, they’d be lucky to have you.
  • Good luck with the interview tomorrow, what time is it?
  • Good luck at the interview, and remember to ask about the team.

  • Knock it out of the park tomorrow, Jay.
  • You’re going to knock it out of the park.
  • Knock it out of the park, and then call me.

Text "you’ll do great" the night before, and say "good luck with the interview" on the morning itself.

Ways to Say Good Luck Before a Performance

In a theatre "good luck" is bad luck, so a performer gets a wish that means the opposite.

Break a leg: the standard wish for an actor, a dancer, a musician, or a speaker, and it comes from a stage superstition that a direct wish brings bad luck. It fits friends and strangers backstage, and the reply is "thanks".

  • Break a leg tonight, Mia, we’re in the third row.
  • Break a leg, everyone, and enjoy the show.
  • I can’t be there, but break a leg!

Have a great show: the plain wish for a performer, and it fits a parent, a friend, or a stage manager who prefers to skip the idiom.

  • Have a great show, love, we’ll be at the stage door after.
  • Have a great show, Tom, the house is full.
  • Have a great show, and don’t forget your cue in the second act.

Toi toi toi: the wish that opera singers and classical musicians say instead of "good luck", said quickly three times. It stays backstage and sounds odd anywhere else.

  • Toi toi toi, Elena, you sound wonderful in the second aria.
  • Toi toi toi to the whole cast.
  • Toi toi toi, and see you at the party afterwards.

Enjoy it out there: a wish that asks the performer to have fun rather than to be perfect, and it fits a nervous first-timer.

  • Enjoy it out there, Ravi, the crowd is on your side.
  • Forget the judges and enjoy it out there.
  • Enjoy it out there, you’ve earned this.

A direct "good luck" to an actor is the one wish to avoid.

  • Good luck tonight, Mia, we’re in the third row. (to an actor before the show) ❌

Actors treat "good luck" as a curse before a show, so the wish is "break a leg" or "have a great show".

  • Break a leg tonight, Mia, we’re in the third row. ✅

Say "break a leg" to any performer, and keep "toi toi toi" for singers and orchestras.

Ways to Say Good Luck Before a Match or Race

A sports wish is short and loud, and it fits a player, a runner, or a whole team.

  • Play well out there, lads.
  • Play well today, and enjoy the final.

Bring it home: a wish that means "win it for us", and it fits a team in a final or a runner in the last leg of a relay.

  • Bring it home, girls, the whole school is watching.
  • One more set, bring it home!
  • Bring it home tonight, Rovers.

Give it everything: a wish that asks for full effort, and it fits a race or a match where the result is uncertain.

  • Give it everything today, Leo, and leave nothing on the track.
  • Give it everything, and we’re proud of you whatever the score.
  • Give it everything in the second half.

Say "play well" to one person, and "bring it home" to a team.

Ways to Say Good Luck Before a Trip or a Move

A travel wish names safety rather than luck, and a move wish names the new home.

Safe travels: the most common wish for a journey, and it fits a colleague flying to a conference, a friend going home, or a parent driving in the dark.

  • Safe travels, Amir, and message me when you land.
  • Safe travels back to Manchester.
  • Safe travels tomorrow, the roads are icy.

Bon voyage: the French wish for a journey, used in English for a long trip by sea, by air, or by road, and it fits a card or a farewell party.

  • Bon voyage, you two, enjoy every minute of the cruise.
  • Bon voyage! Send us photos from Lisbon.
  • Bon voyage, Dr Malik, and thank you for a wonderful year.

Good luck with the move: the wish for someone changing house, city, or country, and it fits a text, a card, or a goodbye by the van.

  • Good luck with the move, Jess, and shout if you need boxes.
  • Good luck with the move to Berlin, I’ll visit in the spring.
  • Good luck with the move on Saturday, I hope it stays dry.

Say "safe travels" for any journey, "bon voyage" for a holiday, and "godspeed" for a journey with real risk.

Funny Ways to Say Good Luck

Funny wishes are for friends who share your jokes, and each one plays on a film line or a mock threat.

May the Force be with you: a line from a space film, said as a joke wish before an exam or a match. It fits friends and family who know the film.

  • May the Force be with you in the chemistry exam.
  • May the Force be with you, young one.
  • Big day? May the Force be with you.

May the odds be ever in your favour: a line from a book and film about a deadly contest. It works as a joke before a task with many rivals: an interview, a ticket sale, or a job lottery.

  • Two hundred people applied? May the odds be ever in your favour.
  • May the odds be ever in your favour in the seat lottery.
  • May the odds be ever in your favour, and take snacks.

Don’t mess it up: a mock threat that means "good luck", said with a grin to a close friend or a sibling.

  • Don’t mess it up, little brother, I’ve told everyone you’re a genius.
  • Good luck, and don’t mess it up!

Good luck, you’ll need it: a tease that means "this is hard", and it fits friends who joke about each other. To a stranger it sounds unkind.

  • Driving with Dad again? Good luck, you’ll need it.
  • Good luck, you’ll need it, that professor never gives an A.
  • You’re cooking for her parents? Good luck, you’ll need it.

"Good luck with that" is the trap among the funny wishes, because with a flat voice it means "that will never work".

  • Good luck with that. (flat voice, to a friend who wants to pass the driving test) ❌

Said flatly, "good luck with that" is sarcasm, so a sincere wish takes a name and the event.

  • Good luck with the test, Ben, you’ll pass this time. ✅

Save the joke wishes for people who will laugh, and say "good luck with the test" when you mean it.

How Do You Reply When Someone Says Good Luck?

The reply to a good luck wish thanks the speaker first, and then it adds one short line about the event or about the other person.

Thanks, I’ll need it: the most common reply, and it makes a small joke about the task being hard.

  • Good luck with the exam! Thanks, I’ll need it.
  • Best of luck tomorrow. Thanks, I’ll need it, the panel is huge.
  • Good luck on your first day. Thanks, I’ll need it!

Thank you, fingers crossed: a reply that agrees the result is uncertain, and it fits a visa, a job reply, or a medical result.

  • Good luck with the visa. Thank you, fingers crossed.
  • I hope it goes well. Thank you, fingers crossed, we hear on Monday.
  • Fingers crossed for you! Thank you, fingers crossed.

Cheers, I’ll let you know: a casual reply that promises news later, and it fits friends and colleagues.

  • Good luck with the interview. Cheers, I’ll let you know.
  • Best of luck, mate. Cheers, I’ll let you know how it goes.
  • Smash it tomorrow. Cheers, I’ll let you know!

Thanks, you too: the reply when both of you face the same test, match, or first day. When the other person has no event, it sounds wrong.

  • Good luck in the exam. Thanks, you too.
  • Good luck today, we’re all nervous. Thanks, you too, see you after.
  • Best of luck, everyone. Thanks, you too.

Thanks: the full reply to "break a leg", because a performer never returns the wish to someone in the audience.

  • Break a leg tonight! Thanks, see you after.
  • Break a leg, Mia. Thanks, I’m terrified.
  • Toi toi toi. Thanks, you too (to another singer).

"You too" is the reply that goes wrong most.

  • Good luck with the surgery tomorrow. (reply) You too. ❌

"You too" returns the wish, and the other person is not having surgery, so the reply is "thanks" plus a line.

  • Good luck with the surgery tomorrow. (reply) Thanks, I’ll be glad when it’s over. ✅

Answer a good luck wish with "thanks" and one short line, and say "you too" only when the other person faces the same event.

More Everyday English Phrases

FAQs

Q1. How do you say good luck in a professional way?

"I wish you every success" is the most formal wish, and "best of luck with" plus the name of the event is the most natural one in an office. "Wishing you success" and "all the best in your new role" fit a card or a farewell email. Slang such as "knock ’em dead" and "smash it" stays out of professional writing.

Q2. Is it OK to say good luck?

Yes, "good luck" is polite at every level, from a friend to a client, and it never sounds rude. The two exceptions are a theatre, where performers say "break a leg" instead, and a flat "good luck with that", which sounds sarcastic. Add a name or the event to keep the wish warm.

Q3. Why is saying good luck bad luck?

The idea comes from the theatre, where actors believe that a direct wish for luck brings the opposite result. The wish for a performer is "break a leg", and opera singers say "toi toi toi". Outside a theatre "good luck" is a normal, kind wish with no bad luck attached.

Q4. What can you say instead of good luck?

"Best of luck", "all the best", and "you’ve got this" are the three most common replacements, and "fingers crossed" fits a result the person cannot control. Before a performance the replacement is "break a leg", before a journey it is "safe travels", and in a formal email it is "I wish you every success".

Q5. What is a synonym for best of luck?

"Good luck" and "all the best" mean the same as "best of luck", and "I wish you the best of luck" is the full formal form. "Wishing you the best of luck" is the version for a card. In a text between friends "you’ve got this" replaces all of them.

Q6. Can break a leg be used professionally?

No, unless the professional setting is a stage, a concert hall, or a film set, where "break a leg" is the standard wish. In an office it sounds like a joke, so a colleague giving a presentation gets "best of luck with the presentation". Between friends who work together it passes as humour.

Q7. When do you say good luck to someone?

Say "good luck" before the event, never after it, and only when the person has something to do or to wait for: a test, an interview, a match, a trip, a move, or a result. After the event the line changes to "well done" or "congratulations" if it went well, and "bad luck" or "never mind" if it did not.

Q8. What do you say when someone says good luck to you?

Say "thanks" first, then add a short line: "thanks, I’ll need it", "thank you, fingers crossed", or "cheers, I’ll let you know". "Thanks, you too" fits only when the other person faces the same event. A performer replies to "break a leg" with "thanks" and never with "you too".
