What Is Reddit Karma? The Score Explained
Reddit karma is the public score next to your username that reflects the upvotes and downvotes your posts and comments have received. It can't be spent on anything, but many subreddits require a minimum amount of it before they let you post or comment.
Reddit's own help center describes karma as a reflection of your votes rather than an exact count, and notes that some communities gate posting behind it to prevent spam. That one sentence explains most of why the number matters. Here's the full picture: how it's calculated, the types, what it gates, and what it's actually worth.
How karma is calculated
When someone upvotes your post or comment, your karma goes up. When someone downvotes, it goes down. Your profile shows the running total across everything you've ever contributed.
The relationship isn't one-to-one. Reddit applies its own adjustments, so a post with 10,000 upvotes won't add exactly 10,000 karma. The official help page puts it plainly: karma is "just an approximate reflection of your votes." Votes that look suspicious, like bursts from brand-new or coordinated accounts, can be discounted before they ever count. The score is designed to measure genuine community approval, and Reddit actively defends that design.
Karma can also go negative. Enough downvotes on enough posts will drag your total below zero, and a negative score is a louder signal to communities than a zero one.
Post karma vs comment karma
| Type | Earned from | How it reads to others |
|---|---|---|
| Post karma | Upvotes on links and text posts you submit | Can spike overnight from one breakout post |
| Comment karma | Upvotes on your comments in threads | Builds slowly, signals consistent real participation |
| Awarder / other karma | Smaller categories tied to community recognition | Minor. Few people look at it |
Experienced redditors quietly weigh comment karma higher. One lucky post can inflate post karma in a day, but a healthy comment total usually means someone who shows up and contributes across many threads. Some automod filters check the two separately for the same reason.
How karma is earned in practice
There's no trick that beats the obvious answer: post and comment things a community actually wants to read, in the places they want to read them. Within that, a few approaches pay off faster than others.
- Comment early on rising posts. A useful comment near the top of a fast-growing thread gets seen by everyone who opens it. This is the single most efficient karma source for a new account.
- Answer real questions. Specific, helpful answers keep collecting upvotes long after you wrote them.
- Read the room first. Each subreddit rewards different things. Humor lands in one, expertise in another, and misjudging that earns downvotes instead.
- Post when the community is awake. Karma follows visibility, and visibility follows active voters. The mechanics behind that are covered in how Reddit's algorithm works.
- Skip reposts and low-effort filler. Communities downvote them fast, and negative karma is just as real as positive.
What karma actually gets you
Karma can't be cashed in, so newcomers tend to dismiss it. Then they hit the walls it controls.
Posting gates. Many subreddits set minimum karma requirements to post or comment. Reddit's help center confirms communities do this to keep spam out. Below the threshold, your posts get silently filtered no matter how good they are.
Rate limits. Low-karma accounts face stricter limits on how often they can post and comment. Established karma loosens them.
Credibility. People check karma and account age before trusting a recommendation, engaging with an AMA, or taking a claim seriously. A near-zero account reads as a possible bot or throwaway, and gets treated like one.
The useful mental model is a passport. It doesn't buy anything, but it determines which doors open.
The cold-start problem
New users hit a chicken-and-egg wall: you need karma to participate in the good communities, and you build karma by participating. That friction is deliberate. It's what keeps spam accounts from posting on day one.
The way through is sequencing. Start in large, open subreddits without strict minimums, earn your first comment karma there, and graduate into gated communities once you clear their thresholds. It usually takes a few weeks of light, genuine activity rather than months. Our guide to growing on Reddit lays out a realistic first-month sequence, and can you buy Reddit karma covers the paid shortcut question honestly, including what Reddit's rules say about it.

The short version
Karma is Reddit's reputation layer: a vote-driven public score that gates posting rights, rate limits, and how seriously people take you. Comment karma is worth more per point than post karma. There's no "good" number in the abstract, just the thresholds of the subreddits you care about. Earn it by being useful in open communities first, then move to the gated ones. The people with the most karma are generally the ones who stopped tracking it.
Two edge cases worth knowing
Does deleting a downvoted post restore my karma?
No. Deleting removes the post but the karma change stays. If something is collecting downvotes, deleting it stops the bleeding going forward but doesn't undo it.
Do upvotes on old content still add karma?
Yes. Votes count whenever they arrive, which is why a genuinely useful answer in a searchable thread can keep paying out for years. It's also why answering evergreen questions beats chasing trends if karma is your goal.
