English gives you endless ways to praise someone, but few expressions confuse learners more than “Congratulations on” and “Congratulations for.”
Both sound right sometimes which makes things even trickier.
This guide breaks everything down in simple language. You’ll learn exactly when to use each phrase, why one is more common, and how meaning shifts with context so your congratulatory messages always sound natural.
Let’s dive in.
Most people don’t think about prepositions until one feels off.
Congratulatory phrases are a perfect example. You’ll hear:
- “Congratulations on your new job!”
- “Congratulations for helping the team!”
Both look similar. Both sound kind.
So why do native speakers prefer one over the other in certain situations?
Because “on” and “for” change the focus of the praise.
- “On” connects your congratulations to an achievement, milestone, or event.
- “For” connects your congratulations to an action, behavior, or reason that deserves praise.
Once you understand the difference, your English instantly sounds more natural.
Core Difference in Simple Terms
Here’s the difference in one line:
“Congratulations ON” = result or achievement
“Congratulations FOR” = reason or action
You use on when the outcome matters.
You use for when the behavior matters.
This one sentence will carry you through almost every example.
“Congratulations On”: Meaning and Correct Usage
What it means
“Congratulations on” celebrates a result, achievement, status, or important event.
This is why you hear it in formal settings like weddings, graduations, promotions, and awards.
When to use it
Use “congratulations on” when the subject achieved or reached something, such as:
- A life event
- A milestone
- A career achievement
- A status change
- A new possession
- A completed action
Examples
| Event / Achievement | Correct Phrase |
|---|---|
| Marriage | Congratulations on your wedding |
| Graduation | Congratulations on graduating |
| Job | Congratulations on your new job |
| Promotion | Congratulations on your promotion |
| Award | Congratulations on winning the award |
| New Home | Congratulations on your new house |
| Baby | Congratulations on the birth of your baby |
| Success | Congratulations on your success |
Notice that all of these focus on something achieved or completed.
Why “on” is standard
It links the praise to a specific point:
Congratulations on reaching this milestone.
The preposition “on” behaves like “on the occasion of,” which matches celebrations and achievements perfectly.
“Congratulations For”: Meaning and Correct Usage
What it means
“Congratulations for” praises a reason, action, or behavior that deserves recognition.
You’re appreciating what they did rather than what they achieved.
When to use it
Use it when you’re focusing on:
- Effort
- Good behavior
- Positive choices
- Courage
- Helping others
- Trying something difficult
Examples
| Action / Reason | Correct Phrase |
|---|---|
| Helping someone | Congratulations for helping your friend |
| Volunteering | Congratulations for volunteering this year |
| Good decision | Congratulations for making a brave choice |
| Hard work | Congratulations for working so hard |
| Dedication | Congratulations for your commitment |
| Leadership | Congratulations for leading the team well |
Notice how each example highlights behavior, not just the result.
Tone shift when using “for”
Using “for” feels more conversational, personal, and emotional because it highlights the person’s character.
Congratulations for being so dedicated.
That sentence praises who they are, not just what they achieved.
Side-by-Side Comparison (Clarity Table)
Here’s a quick table to remove any remaining confusion:
| Situation | Correct Choice | Why |
|---|---|---|
| Success or milestone | Congratulations on your success | Celebrates achievement |
| Graduation | Congratulations on graduating | Celebrates completed event |
| Good behavior | Congratulations for helping others | Praises action |
| Winning something | Congratulations on winning | Focus on achievement |
| Trying hard | Congratulations for working hard | Praise for behavior |
| Wedding | Congratulations on your wedding | Event or milestone |
| New baby | Congratulations on the baby | Milestone |
| Choosing well | Congratulations for making a wise decision | Represents action |
Nuances You Should Know
Sometimes both forms work, but they express slightly different feelings.
Nuance 1: Action vs Achievement
- Congratulations on finishing the marathon
- Congratulations for training so hard for the marathon
See the difference?
“On” praises the finish.
“For” praises the effort.
Nuance 2: Formal vs informal tone
- “On” feels formal and widely accepted.
- “For” feels emotional and personal.
Nuance 3: When both sound okay but aren’t identical
- On: Congratulations on winning the contest → Focus on result
- For: Congratulations for winning the contest → Sounds like you’re praising the act of winning
Native speakers prefer “on” in this case.
Nuance 4: Cultural perception
In most English-speaking countries:
- “Congratulations on” = Standard, safe, widely used
- “Congratulations for” = Used but less common
Always choose “on” if you’re not sure.

Even without data, you’ll easily notice:
“Congratulations on” is far more common.
It dominates:
- Formal writing
- Emails
- Social media

- Wedding invitations: “Congratulations on your marriage”
