Reddit Karma Growth Calculator

1. Note your total karma today. It shows on your profile, with post karma and comment karma listed separately.
2. Enter an earlier reading and the number of days between the two. A screenshot or a note from last month works.
3. Add a target karma and the posts and comments you made in the period. Both are optional.

Reddit karma growth is the change in your karma over a set time. Karma itself is a score on your profile. Reddit Help describes it as a reflection of the upvotes and downvotes you receive on your posts and comments.

Reddit Help adds one caution: karma is an approximate reflection, and upvotes and karma do not have a 1:1 relationship. Ten upvotes do not always mean ten karma. Reddit does not publish the exact method.

Growth rate matters for practical reasons. Some communities require a certain amount of karma before a new member can post, which Reddit describes as a measure against spam. The Contributor Program also uses karma tiers: 100 to 4,999 total karma for a Contributor and 5,000 or more for a Top Contributor.

This page does not score your account or guess what Reddit will do. It measures the pace you have already set.

The calculator draws a straight line through your two karma readings.

1. It subtracts the earlier reading from the current one. That is the karma gained.
2. It divides the gain by the days between the readings.
3. It multiplies the daily rate by 7, 30 and 90 for the weekly, monthly and projected figures.
4. It divides the karma still needed by the daily rate to give days to the target.

No weights for community size, content type or posting hour are applied. Reddit publishes none, so any such number would be a guess.

Example values only. An account had 1,200 karma 30 days ago and has 1,560 today. The owner made 90 posts and comments in that time and wants to reach 5,000.

At the same pace the account passes 5,000 in about 287 days, or roughly 9.6 months. The figure moves as soon as the pace changes.

How Much You Contribute

More posts and comments give more chances to earn votes. The example account earned 4 karma per contribution. The same 360 karma from 45 contributions would be 8 each.

How Each Contribution Is Received

Reddit Help says upvotes show that people think content adds to a community. Downvotes lower karma, so the gain can be negative.

The Length of Your Window

One popular post inside a short window inflates the rate. In the example, the last 7 days alone might show 60 karma, or 8.57 per day, which moves the target to 402 days.

Community Rules

Each community sets its own rules, and moderators enforce them. Removed posts earn nothing.

The Approximate Count

Karma is not a 1:1 count of votes. Two periods with the same votes may show different karma changes.

Many karma tools print a growth score out of 100. The two approaches rest on different things.

A straight line is simple, and it is honest about what it knows. To compare how single posts were received, the Reddit post title calculator works on your own post data.

Meeting a Community Requirement

A new account at 85 karma, gaining 4.64 per day, reaches a 100 karma requirement in about 4 days. Count the days between two dates with the date calculator.

Tracking a Monthly Habit

Record your karma on the first of each month and compare rates. The percentage calculator shows the change between two months.

Checking Progress Toward a Program Tier

Reddit lists 100 total karma and 5,000 total karma as the two Contributor Program tier lines. Karma is one condition among several, so read the full eligibility rules on Reddit Help.

Reviewing Shared Content

Posts shared to more than one community can be compared with the Reddit crosspost impact calculator.

1. Counting One Karma per Upvote

Reddit states that upvotes and karma are not 1:1. Use the karma number on your profile, not a vote tally.

2. Measuring Over a Few Days

A short window swings with single posts. Thirty days or more gives a steadier rate.

3. Treating the Projection as a Promise

The line assumes your pace stays the same. It will not.

4. Trusting Best-Time and Best-Format Tables

Reddit publishes no posting hours or content-type multipliers. Tables that list them are third-party guesses.

5. Chasing Karma with Vote Tricks

Reddit prohibits vote manipulation. Its rules name multiple accounts, voting services, coordinated voting and automated means to manipulate karma.

6. Mixing Post Karma and Total Karma

Use the same figure for both readings. Total karma at the start and post karma at the end gives a false drop.

The arithmetic is exact for the numbers you enter. The projection is only as good as the idea that the future looks like the past.

Reddit does not publish a formula. Reddit Help says karma reflects the upvotes and downvotes on your posts and comments, and that upvotes and karma do not have a 1:1 relationship.

It depends on your own pace. Divide the karma you still need by your karma per day. An account at 85 karma gaining 4.64 per day needs about 4 days.

No official benchmark exists. Reddit publishes no average rate, so the useful comparison is your own rate this month against last month.

Yes. Downvotes on your posts and comments lower karma. A falling period shows here as a negative rate, with no date for the target.

Reddit Help says some communities require a certain amount of karma before you can post, as a measure against spam. Each community sets its own level.

Reddit lists at least 100 total karma among the eligibility criteria. A Contributor has 100 to 4,999 total karma and a Top Contributor has 5,000 or more. Other conditions also apply.

Both show on your profile and add to total karma. Reddit Help does not publish separate rules for each, so enter total karma for both readings.

Yes. Reddit prohibits vote cheating and manipulation, including coordinated voting, voting services, multiple accounts and automated means to manipulate karma.

Reddit publishes no weights for those. A tool that applies them is using guesses, so this page uses only your measured rate.

No. The maths runs in your browser and nothing is sent to us. Save keeps a result only in this browser.
