What's the Minimum Daily Budget for Reddit Ads in 2026?

Reddit's official minimum daily budget is $5/day per campaign, with a $10 lifetime campaign minimum. For Max Campaigns — Reddit's newer AI-optimized campaign format — the minimum rises to $20/day, or $620 for a lifetime budget. Neither figure is enough to actually optimize a campaign; that takes closer to $50-$100/day.

The gap between "allowed" and "workable"

Reddit will accept and serve a $5/day campaign without complaint. The catch is volume: at that spend level, a campaign typically generates only 2-7 clicks per day. Gathering enough data for Reddit's delivery system to identify which placements, audiences, or creative are working can take months at that pace — Reddit is still serving the ads, but neither you nor the algorithm is learning much from them in any reasonable timeframe.

Why Max Campaigns carry a higher floor

Max Campaigns use automated, AI-driven optimization across placements and bidding, which is a more data-hungry process than a standard manually-configured campaign. Reddit's $20/day minimum for this format reflects that the automation needs a larger baseline of activity to make its own placement and bid decisions — setting a Max Campaign at the bare $20/day minimum still leaves relatively thin margin for the system to test and learn.

What advertisers actually budget

• Bare minimum (technically live, rarely useful): $5/day standard campaigns, $20/day Max Campaigns
• Testing floor experts recommend: $50/day, enough to accumulate a meaningful number of clicks and early signal within a week or two
• Optimization-ready budget: $50-$100/day or more depending on the campaign objective — conversion campaigns generally need more volume than awareness or traffic campaigns to find a stable cost-per-result

Why this matters more on Reddit than on larger platforms

Reddit's ad inventory and auction dynamics are less mature than Google's or Meta's, and its audience is smaller and more niche per subreddit. That means the algorithm has less historical data to lean on when a new campaign launches, which raises the bar for how much fresh activity your own budget needs to generate before delivery stabilizes. A campaign that would comfortably learn on $30/day on a larger platform often needs more room on Reddit to reach the same confidence level.

Standard campaigns vs. Max Campaigns budgeting

The two formats aren't just priced differently at the minimum — they call for different budgeting logic entirely. A standard, manually-configured campaign lets you control targeting, placement, and bids directly, so a modest $30-$50/day budget can still be useful for narrowly-targeted subreddit tests where you're not relying on the algorithm to find an audience for you. Max Campaigns hand that targeting and bidding work over to Reddit's automation, which means the $20/day minimum is closer to a true floor rather than a starting point — the automated system needs enough daily volume to make its own placement and bid decisions, and underfunding it tends to produce inconsistent, hard-to-read results rather than a controlled, if smaller, test.

Bottom Line

Don't plan a Reddit Ads campaign around the $5/day (or $20/day for Max Campaigns) technical minimum — treat those as "the ad will run," not "the ad will optimize." Budget at least $50/day if you want enough data within a couple of weeks to judge whether the campaign is working.
