What's the Minimum Budget for TikTok Ads in 2026?

TikTok's official minimum ad budget in 2026 is $50 at the campaign level and $20 per day at the ad group level, according to TikTok Ads Manager's own budget guidelines. Those are the platform's hard technical floors — the smallest amount TikTok will let an advertiser launch with — not a realistic working budget for actually running a campaign.

Campaign-level vs. ad group-level minimums

TikTok Ads Manager lets advertisers set a budget at either the campaign level or the ad group level, and each has its own floor. A campaign budget, which caps total spend across every ad group inside it, has a $50 minimum. An individual ad group budget, whether set as a daily budget or a lifetime budget, has a $20-per-day minimum. An advertiser running several ad groups under one campaign needs to clear both floors — the campaign total and each ad group's own minimum — for the campaign to go live.

Why the official minimum isn't a working budget

TikTok's ad-delivery algorithm needs a meaningful volume of conversion events to optimize delivery — the platform generally can't exit the learning phase for an ad group with fewer than roughly 50 conversion events in a week. At a $25 cost per action, hitting that 50-conversion threshold requires spending around $1,250 in a week, or about $179 a day per ad group — nearly nine times the platform's stated $20 daily minimum. An ad group funded only at the technical minimum will typically stay stuck in the learning phase, where delivery is unstable and costs run higher than they will once the algorithm has enough data.

Daily budget vs. lifetime budget

TikTok offers both budget types at the ad group level. A daily budget sets the average amount TikTok will spend per day, which can fluctuate day to day as the algorithm looks for opportunities, while a lifetime budget sets a fixed total to be spent across the whole flight of the campaign, which TikTok then paces automatically. Neither budget type changes the $20-per-day minimum — it applies whether the advertiser is setting a strict daily cap or letting TikTok pace a lifetime total.

What to budget instead

Rather than starting from TikTok's $50/$20 floors, work backward from the target cost per action and the roughly-50-conversions-per-week threshold: multiply the expected CPA by 50, then divide by 7 to get a realistic daily ad group budget that gives the algorithm a real chance to optimize. A campaign testing multiple ad groups should expect to fund each one at that higher level, not split the platform's minimum across several ad groups at once — spreading a small budget too thin across ad groups is one of the more common reasons a new TikTok account never leaves the learning phase.

Bottom Line

Treat TikTok's $50-campaign / $20-daily-ad-group minimums as what's required to launch, not what's required to succeed — budget for roughly 50 conversions per ad group per week if the goal is a campaign that actually exits the learning phase and delivers stable results.
