How to get comment karma on Reddit

Comment karma is the half of your karma that shows people how you talk.

It is also a number a subreddit can check on its own, and even count only inside its own walls.

Here is why it matters, where it comes from and how long it takes, in 4 parts, with 3 things you can copy. If you want the whole karma picture first, start with how to get karma on Reddit.

Save this. It is the slow, reliable half of karma.

Short answer

You get comment karma when people upvote your comments. The comments that earn it answer a real question early in a thread, in a subreddit small enough that people read the new posts, from someone who knows the topic. Most comments earn little or nothing, and a few earn most of it, so steady volume in the right rooms matters more than any one comment. Track what lands, and do more of that.

Key takeaways

• A subreddit can check comment karma on its own, and it can count only the comment karma you earned in that room.
• Rankhog treats an account as established at 50 total karma with at least 20 from comments.
• New threads in small rooms are where comments get seen.
• Reddit hides vote counts for the first hours, so don't judge a comment too early.
• Most comments earn nothing. Log yours for a few weeks and you will see which rooms reward you.

1. Why does comment karma matter more than post karma?

Because many subreddits check it on its own. AutoModerator can compare your comment karma with a minimum, separately from post karma, and it can count only the comment karma you earned in that subreddit. An account full of post karma from a lucky meme can still fail a comment minimum.

Reddit's full AutoModerator documentation lists comment karma, post karma and total karma as separate checks, plus the same three counted only inside the subreddit. Each room picks which ones it uses.

Here is a real one. r/GrowthHacking's published rules, as Rankhog's guide last checked them on 29 September 2026, ask for at least 100 karma earned in that community before you share your own blog post or product. That is community karma, and only comments and posts in r/GrowthHacking count toward it.

Rankhog's own warm-up draws its line the same way. It treats an account with at least 50 total karma and at least 20 comment karma as established. An account with 500 post karma and 5 comment karma isn't.

To see where your account stands, run it through the free Reddit karma checker. It shows the split and which published minimums the account clears.

That split is why I warm accounts up with comments first. Rankhog warms up accounts you own, slowly, in your own browser.

2. Where do comments actually earn karma?

In new threads, in small rooms, on questions you can really answer. A comment early in a thread is seen by most of the people who will ever read it. A comment in a small subreddit is read by people who care about the topic. A comment that answers the question gives them a reason to vote. Miss any of the three and the comment mostly sits there.

Here is the check I run before I write a comment. Copy it.

1. The thread is new, ideally hours old, not days.
2. The subreddit is small enough that people read the new posts.
3. The question has no good answer yet.
4. I know the answer from doing it, not from guessing.
5. The rules of the room allow what I'm about to say.

If a thread fails two of those, I skip it. There is always another one.

Two places people forget.

Replies to replies. When someone answers your comment, a short, friendly reply is the easiest upvote on Reddit. It also shows mods you hold a conversation, not just a position.

Your own threads. When you post a question, answer the people who reply. Those comments count too.

And one place to skip: giant threads hours after they hit the front page. Your comment lands under hundreds of others, and almost nobody scrolls that far.

3. How long does it take to get comment karma?

Longer than people expect, and unevenly. Most comments earn nothing, and a handful earn most of your total. You can't tell in advance which ones those will be, so the only lever you control is volume in the right rooms. Two or three good comments a day in small subreddits is a pace that adds up over weeks.

I learned the uneven part the hard way. When I audited 130 comments from Rankhog's warm-up accounts in October, the median one never moved past the point it started with, and three comments carried more than half of all the karma. Karma farming vs warming up your account has the rest of that story.

Two more things slow the count down, and both are normal.

Reddit hides vote counts at first. Its help page on hidden vote counts says votes aren't displayed for the first few hours to prevent vote manipulation, and some communities hide them for a short time too.

And karma isn't one point per vote. Reddit's karma page calls it an approximate reflection of your votes.

So measure something you control. Rankhog's warm-up moves an account on after 10 comments are still up 24 hours later and 7 days pass with no removal, whatever they scored. I would use the same yardstick by hand.

Here is the log I would keep for the first few weeks. Copy it into a spreadsheet.

After two weeks, sort it by subreddit. The rooms where your comments stay up and get replies are your rooms. Spend more time there and less everywhere else.

4. What costs you comment karma?

Downvotes take it away, and a few habits attract them: arguing to win, jokes in serious threads, links nobody asked for, and the same comment pasted in several places. A removed comment earns nothing at all, because nobody sees it. The fix is simple: write fewer, better comments in rooms you understand.

Karma reflects downvotes as well as upvotes, according to Reddit's karma page. Reddit's AutoModerator documentation also notes that comment karma won't go below minus 100, so even a bad week has a floor.

Removed comments are the quiet cost. If a comment breaks a room's rules, AutoModerator or a mod can remove it, and you may not get a message. Why AutoModerator removed your Reddit post shows how to check. Comments that keep vanishing earn you nothing, however good they are.

Here is the weekly small-room routine I would run alongside the log. Copy it.

1. Monday: pick three small subreddits for the week, one from your job, one from a hobby and one where you're learning.
2. Every day: run the five-point check, then comment two or three times.
3. Every day: reply to anyone who replied to you.
4. Friday: open the week's comments in a private window and fill in the log.
5. Sunday: drop the room that gave you nothing, and try a new one next week.

If your account is brand new, how to warm up a Reddit account puts this inside a day-by-day plan.

What I don't know yet

• Reddit doesn't publish how it turns votes into karma, so I can't tell you how many upvotes a point takes.
• My audit came from a handful of big general subreddits. Small hobby rooms may reward comments very differently.
• I don't know how many subreddits check comment karma rather than total karma. Most keep their AutoModerator rules private.

Who this is not for

If you already have a few hundred comment karma from years of normal use, you're done. Spend the time on the rooms you want to post in.

If you need a subreddit that asks for a high number this week, comment karma won't arrive in time. Post somewhere your account already qualifies.

What to do next

Today, in this order:

1. Check your karma split with the karma checker.
2. Pick three small subreddits for this week.
3. Write two comments that pass the five-point check.
4. Start the log.
5. Come back tomorrow and reply to anyone who replied.

Check. Pick. Comment. Log. Reply.

Thanks for reading. If you'd rather not keep the log yourself, that is the job I built Rankhog for. Rankhog warms up accounts you own, slowly, in your own browser.
