Minimum Bids and Budgets: How Much Do Reddit Ads Cost

How much do Reddit ads cost?

Anyone asking how much do Reddit ads cost hits the same wall on Reddit's own documentation: Reddit prices ads through a live auction and its current help center publishes no rate card, no minimum bid and no minimum daily budget. The only price Reddit commits to in writing is the one you set yourself. Its Budgets and Bidding article states the position plainly, that Reddit Ads is "an auction-based ads platform where your ads compete against others to reach redditors" and that "we don't guarantee your ad group will spend through its budget."

What Reddit does document precisely is the billing model: which user action turns into a charge, and which lever you pull to control the price of that action. Everything else you will read about Reddit ad costs, including every average CPM and average CPC figure, comes from someone else's account data.

What action does Reddit actually bill you for?

The campaign objective decides the billable action, and Reddit publishes the full mapping in its Campaign Objectives article.

Objective	Optimizes for	You pay for
Brand awareness and reach	Impressions	Cost per thousand impressions (CPM)
Traffic	Clicks	Cost per click (CPC)
Conversions	Conversions	oCPM on lowest cost, CPC on cost cap
Video views	Views	Cost per view (CPV)
App installs	App installs	oCPM on lowest cost, CPC on cost cap
Catalog sales	Catalog sales	Cost per click (CPC)
Lead generation	Clicks	Cost per click (CPC)

Two objectives change their billing model based on the bid strategy you pick, which is the detail most cost guides skip. Choose lowest cost on a conversions or app installs campaign and you are billed on optimized cost per mille, meaning you pay for impressions while Reddit optimizes toward the conversion. Choose cost cap on the same objective and you are billed per click instead.

What is the minimum bid on Reddit ads?

Reddit publishes no minimum bid today. The live Budgets and Bidding article, which still sits at the URL slug How-much-do-Reddit-Ads-cost, covers objectives, spend caps, budget types and bid strategies and contains no minimum figure of any kind.

Reddit did publish one. The version of that same article archived in December 2021 carried an explicit FAQ, and the numbers below are what it said. Treat them as history, not as a current rate:

Targeting	Minimum CPM	Minimum CPC	Minimum CPV
US, UK and Canada	$3.50	$0.10	$0.01
All other locations	$1.00	$0.05	$0.01

The $0.10 minimum CPC that shows up in agency roundups and in search result snippets traces back to that archived table and to nothing newer. The same is true of the frequent claim that Reddit runs a second price auction clearing at the second highest bid plus one cent. Reddit's live documentation describes an auction and says your bid, targeting and creative determine auction performance. It does not publish a clearing rule, so that description is unverified against the platform.

Is there a minimum daily budget for Reddit ads?

Not one that Reddit publishes now. The $5 per day figure repeated across the web is real and was Reddit's own, but it comes from pages Reddit retired. The archived 2021 cost article answered "Is there a minimum required budget?" with "Yes, we require a budget of at least $5.00/USD per day," and an older billing FAQ stated that "the minimum daily spend for an ad on our self-serve platform is $5." Neither sentence survives on any live Reddit help page.

What Reddit publishes instead is a recommendation pointing in the opposite direction. Its Standard Campaigns article, under advice on segmenting campaigns, tells advertisers: "Don't spread yourself too thin. Each ad group should have a daily budget of at least $50." That is guidance about getting usable data out of an ad group, not a floor the platform enforces, and the gap between $5 and $50 is the gap between what the system accepts and what Reddit thinks will work.

What else changes what you actually spend?

Five documented mechanics move real spend away from the number you typed into the budget field.

Your ad group can overspend. Reddit's note is unambiguous: "Since Reddit Ads relies on real-time, live auctions to deliver ads to users, your ad group may overspend its budget by up to 20%." Budget is a target with a published tolerance, not a ceiling.

Your ad group can also underspend. Reddit calls this under-delivery and refuses to guarantee that a budget will be spent, so a bid that loses too many auctions leaves part of the budget unspent.

Billable actions have a two hour window. Reddit states that "actions that occur within two hours of the ad being placed will be billed," which is the attribution window sitting behind your CPC line.

Budget edits are not instant. Reddit warns that "changes to budgets may take up to 60 minutes to take effect," so pausing a runaway ad group does not stop the meter immediately.

Ads do not run until a human clears them. Review "normally takes up to 48 business hours but may take a little longer," and ads submitted over the weekend are reviewed the following Monday.

None of those five is the ad itself. Reddit's documentation says bid, targeting and creative decide auction performance, so a cheaper click often comes from a better ad rather than a higher bid, and creator-made ad creative is one way to get one without booking a shoot.

When does Reddit charge your card?

Reddit bills against a rising billing threshold rather than on a fixed schedule. Its current billing article says the threshold "is automatically set to a small amount" when you start and is raised as you make successful payments, without naming any of the amounts. You are charged the first time your balance ever meets the threshold, once a day while your balance sits above it, at the end of the month for any outstanding balance, when you reach your credit limit, and whenever you pay manually.

Reddit used to publish the whole ladder. An archived version of the billing FAQ listed the thresholds as $20, $50, $100, $250, $500, $1,000, $2,000, $5,000, $10,000 and $50,000, moving up one step after a run of successful charges. That list is gone from the live documentation, and the current article points you to the Billing page in Ads Manager to read your own number instead.

Reddit's old billing threshold ladder

1

$20. Where the threshold started before any successful payments.

2

$100. A step reached after a run of successful charges.

3

$1,000. A mid-ladder threshold from the same archived list.

4

$10,000. Near the top of the published ladder.

5

$50,000. The highest threshold Reddit ever listed.

Which cost numbers should you not trust?

Any average CPM or average CPC figure you find is an aggregation of some agency's own client accounts. Reddit publishes no benchmark pricing, so those ranges describe that agency's targeting, creative and vertical, not the auction you will enter. They are unattributable, and they vary by an order of magnitude between sources.

One performance benchmark does come from Reddit, and it is about clicks rather than cost. The Standard Campaigns article tells advertisers to "aim for a performance of ~0.1% - 0.3% CTR" after setup. Pair that with your own conversion rate and you can back into what a click needs to be worth to you, which is a more useful exercise than hunting for someone else's CPC.

Is paid the cheapest way to reach Reddit?

Paid distribution has a documented price and organic distribution has a documented rulebook. A post that reads as an ad gets removed under community rules whatever it cost you to write, and each subreddit enforces its own version of Reddit's self-promotion rule. Getting the targeting right starts with picking the right subreddits rather than with a bid.

There is a third lane: answering the people already asking. RedReplier monitors Reddit, X, Bluesky, Facebook and Hacker News together, ranks mentions by buying intent, and explains why each thread was flagged, which turns a keyword list into a queue of conversations where someone is looking for what you sell. If you are weighing programmatic access instead, Reddit API pricing is a separate line item from ads, and running a business presence on Reddit covers the account side.

Frequently asked questions

Does Reddit publish a minimum bid for ads?

No. Reddit's current Budgets and Bidding article documents objectives, budget types, spend caps and bid strategies without stating any minimum bid. An archived 2021 version of the same article did publish minimums of $3.50 CPM, $0.10 CPC and $0.01 CPV for US, UK and Canada targeting, and $1.00 CPM, $0.05 CPC and $0.01 CPV elsewhere.

What is the minimum daily budget for a Reddit ad?

Reddit does not publish one on any live help page. Its archived cost article required "a budget of at least $5.00/USD per day," and its current Standard Campaigns article recommends that "each ad group should have a daily budget of at least $50," which is advice rather than an enforced minimum.

Can a Reddit campaign spend more than the budget I set?

Yes, by up to 20%. Reddit attributes this to real-time auction delivery and states the tolerance directly in its Budgets and Bidding article. To cap total exposure across a campaign's lifetime, set the optional campaign spend cap, which Reddit says campaigns are never billed beyond.

Do I pay per click or per impression on Reddit?

It depends on your objective. Brand awareness and reach bills on CPM, video views bills on CPV, and traffic, catalog sales and lead generation bill on CPC. Conversions and app installs bill on oCPM under the lowest cost strategy and on CPC under cost cap.

Why did Reddit charge my card before the end of the month?

Because your balance met your billing threshold. Reddit charges the first time your balance ever reaches that threshold, then once a day while the balance stays above it, and again at the end of the month for anything outstanding. The threshold starts small and rises as payments succeed.

How long before a Reddit ad starts spending?

Every ad goes through human review before it can serve, which Reddit says normally takes up to 48 business hours and can run longer depending on content. Ads submitted over the weekend are reviewed the following Monday, and continuous ads begin as soon as they are approved.

What does Reddit mean by ad group under-delivery?

Under-delivery is what Reddit calls a budget that never gets fully spent. Reddit refuses to guarantee that an ad group will spend through its budget, so a bid that loses too many auctions leaves part of it unspent.

How fast do budget changes apply on Reddit?

Not instantly. Reddit warns that changes to budgets may take up to 60 minutes to take effect, so pausing or cutting an ad group's budget will not stop spend right away.

What click-through rate should a Reddit ad get?

Reddit's own Standard Campaigns article gives one benchmark: aim for a CTR of roughly 0.1% to 0.3% once a campaign is set up. Pair that number with your own conversion rate to work out what a click needs to be worth to you, instead of hunting for someone else's CPC.

Does Reddit run a second-price auction?

Reddit doesn't say. The claim that Reddit clears bids at the second highest bid plus one cent shows up across agency posts, but Reddit's live documentation only says your bid, targeting and creative determine auction performance. It publishes no clearing rule, so the second-price claim stays unverified.
