You get karma on Reddit by posting and commenting on things that other redditors upvote. There is no legitimate shortcut. Reddit's own advice is to be a good contributor and let karma follow, and farming or buying karma risks a ban. The reliable way to build it is to genuinely participate in communities you care about.
Karma matters because it is a trust signal, and some communities require a minimum before they will let you post. Here is how to build it the right way, and what to avoid.
How karma is earned
Reddit explains it directly: "You can earn karma by participating in communities that you have an interest in and making posts and comments people enjoy and upvote. The more upvotes you get, the more karma you'll receive." One nuance to expect: karma is not a one-to-one count of upvotes. Reddit notes that "since it's just an approximate reflection, upvotes and karma don't have a 1:1 relationship," so do not try to reverse-engineer a formula.
Practical ways to build karma
The fastest honest way to build karma is to be genuinely useful where people are already talking:
- Comment first. Helpful, specific answers in active discussions earn comment karma quickly and are far harder to get removed than posts.
- Post things people actually want. Share something useful, interesting, or well-timed in a community where it belongs, and make it valuable on its own.
- Start in welcoming communities. Reddit points new users to help: "If you need help building up some karma, check out r/NewToReddit's list of communities that are especially welcoming." Note that r/NewToReddit is a community-run help space, not an official Reddit one.
- Be consistent. A steady history of small contributions builds a genuine account faster than one viral attempt.
What not to do
Reddit's guidance on mindset is blunt: "Don't set out to accumulate karma; just set out to be a good contributor, and let your karma simply be a reflection of your legacy." The shortcuts people reach for all backfire. Buying karma, farming it with reposts, running multiple accounts, or soliciting votes are forms of manipulation. Reddit's Disrupting Communities policy is direct: "Do not manipulate votes, evade enforcement, or otherwise disrupt Reddit communities," and it names "automated means to manipulate karma" specifically. The consequence is real: manipulation can lead to a temporary or permanent ban.
Why you need karma in the first place
Karma gates access. Reddit is explicit that a new account's first post might not show up because "some communities require a certain amount of karma before allowing you to post there. This measure is taken to prevent spamming within the community." There is no sitewide number that unlocks Reddit; these minimums are set per community by its moderators.

Frequently asked questions
How do you get karma on Reddit fast?
There is no legitimate fast track. The quickest honest route is leaving helpful comments in active discussions, since comment karma accrues as people upvote genuinely useful replies. Reddit warns against chasing karma directly, and manipulation to speed it up risks a ban.
How much karma do you need to post on Reddit?
There is no sitewide requirement. Some communities set a minimum karma or account-age threshold to prevent spam, and it varies by subreddit. Build a genuine history in relevant communities before you plan to post where you want to be seen.
Can you buy Reddit karma?
You should not. Buying or farming karma relies on manipulation and multiple accounts, which Reddit's rules prohibit and enforce with temporary or permanent bans. It also produces an account with no real standing in the communities that matter.
Can Reddit karma go negative?
Yes. Because karma reflects downvotes as well as upvotes, heavily downvoted content can push it below zero. Reddit does not publish a specific negative floor, so any exact limit you see elsewhere is unverified.
