The short answer
- Reddit's minimum budget is $5 a day. Reddit recommends at least $50 a day per ad group.
- Billing follows the objective: CPM for awareness and consideration, CPC for traffic and sales, CPV for video views.
- Typical US costs in 2026 are about $4-$10 CPM and $0.50-$2.00 per click.
- A realistic first test is $1,000-$1,500 over a month on one or two ad groups.
- Community targeting is what you pay for: reaching people inside the subreddits where your category is discussed.
Reddit's minimum budget and how budgets work
Reddit's ads help center sets the floor at $5 a day. For reliable optimization it advises a daily budget of at least five times your average cost per action, and at least twice your average CPA for each ad group when one campaign runs several. The minimum lets you launch; the CPA multiple is what gives the auction enough room to learn.
- Daily or lifetime. Each ad group takes either a daily budget (the most to spend each day it runs) or a lifetime budget (the most over its whole run).
- Overspend. Because delivery runs on live auctions, an ad group can overspend its budget by up to 20%.
- Under-spend. Reddit does not guarantee an ad group spends its budget. Weak auction performance means it delivers less. If that is happening, see Reddit ads not spending.
How Reddit bidding works: CPM, CPC and CPV
Reddit sells ads in an auction. Your campaign objective decides what you can be billed for, and your bid strategy decides which of those billing events applies.
| Objective | How you are billed |
|---|---|
| Awareness and consideration | Per 1,000 impressions (CPM) |
| Traffic | Per 1,000 impressions (oCPM) on lowest cost, or per click (CPC) on cost cap |
| Video views | Per view (CPV) |
The bid strategy is the switch: the same traffic campaign is billed on impressions under lowest cost and on clicks under cost cap.
Bid strategies
- Lowest cost gets as many results as possible for the budget, with no cost target. Use it to find your baseline.
- Cost cap aims for as many results as possible within a target cost per action. It may not spend the full budget.
- Manual bidding sets one bid for every auction in the ad group.
Start on lowest cost, read two weeks of results, then set a cost cap a little above the cost per result you actually saw.
Reddit ads cost in 2026: typical US ranges
These are typical ranges, not quotes. Community, creative and objective move them a lot.
| Metric | Typical US range (2026) | What moves it |
|---|---|---|
| CPM | $4-$10 | Community size and demand, season, objective |
| CPC | $0.50-$2.00 | CPM and how native the ad reads |
| Click-through rate | 0.3%-0.8% | Headline, relevance to the community |
| Ad group daily budget | $5 minimum; 5x your average CPA for optimization | How many results you need to judge |
| Monthly test budget | $1,000-$1,500 | One or two ad groups for four weeks |

Community targeting and why it changes the price
Reddit's distinct lever is community targeting: you can put ads in front of people active in specific subreddits, alongside interest and other audience targeting. That is what you pay for on Reddit. An ad for a mechanical keyboard in a keyboard enthusiast community reaches people who already care.
Three things follow for cost:
- Small communities cost more per impression and run out of fresh people quickly. Group related communities into one ad group so it has room to deliver.
- Relevance drives clicks. Redditors skip ads that read like ads. A plain headline that speaks the community's language earns a better CTR, which lowers cost per click on CPM objectives.
- Comments are part of the ad. Promoted posts can collect replies. Answering questions in the comments helps the ad; ignoring them hurts it.
A practical way to pick communities: list the subreddits where people ask for recommendations in your category, check that they are active this month, and sort them into two or three themed ad groups. A brand selling espresso grinders might run one ad group for espresso and home barista communities and a second for broader coffee and kitchen communities, then compare cost per purchase between them after two weeks.
Before you buy, read how the communities talk about your category. The guide on when Reddit ads are worth testing for ecommerce brands covers which products fit.
Worked example: $50 a day for a niche ecommerce brand
A US coffee equipment brand runs one sales ad group at $50 a day, targeting coffee and espresso communities. Assume a $6 CPM, a 0.5% CTR and a 2% conversion rate.
| Step | Monthly (30 days) |
|---|---|
| Budget | $1,500 |
| Impressions ($1,500 / $6 x 1,000) | 250,000 |
| Clicks (0.5% CTR) | 1,250 |
| Cost per click | $1.20 |
| Purchases (2% conversion rate) | 25 |
| Cost per purchase | $60 |
With an average order of $180 and a 50% gross margin, each order earns $90, so a $60 purchase is profitable on the first sale. At a $40 average order the same result loses money, which is why Reddit tends to suit considered purchases more than impulse buys.
Note the budget ceiling too: at up to 20% overspend, a $50-a-day ad group can spend $60 on a given day. Plan cash flow on the higher figure.
Reddit vs Meta and Google on cost
Reddit is rarely the cheapest channel per purchase on day one, and it is rarely the first channel a brand should fund. It earns a place for specific reasons.
| Channel | Strength | When it is the better buy |
|---|---|---|
| Reaching people inside topic communities | Considered purchases people research and debate: software, gear, hobbies, niche products | |
| Meta | Scale, creative-led prospecting, mature conversion optimization | Impulse and visual products, broad consumer audiences |
| Google Search | Capturing people already searching | Any product with existing search demand |
If your product sells on a single image and an impulse, Meta will usually beat Reddit on cost per purchase. If buyers ask strangers for recommendations before they buy, Reddit puts you in that conversation, and its lower CPMs give a test budget more reach. Compare the channels on cost per purchase or per qualified lead after four weeks, not on CPM.
Budget by goal
- Awareness in a few communities: $20-$50 a day on CPM. Judge it on reach, engagement and branded search lift.
- Traffic to content or a product page: $50 a day on CPC. Judge it on cost per engaged visit.
- Sales or sign-ups: $50-$100 a day per ad group with the pixel installed. Judge it on cost per purchase after at least 20-30 conversions.
Below those levels, Reddit can still deliver, but the results will be too thin to tell a good ad from a lucky week.
How to lower Reddit ads cost
- Write like a member, not a brand. Plain titles, specific claims, no hype. Redditors reward candor.
- Group communities by theme so each ad group has a big enough audience to deliver.
- Start on lowest cost, then add a cost cap once you know your real cost per result.
- Keep ad groups near $50 a day instead of spreading $5 across many.
- Answer comments on promoted posts within a day.
- Install the Reddit Pixel or Conversions API before running a sales objective, so bidding learns from purchases.
- Refresh creative when CTR falls; tight communities see the same ad often.
