> Quick answer: TikTok requires a $50/day minimum at campaign level and $20/day at ad group level. Lifetime budgets follow one formula: $20 × scheduled days. Set your first real budget to 10× your target CPA to exit the learning phase faster.
TikTok enforces hard budget floors. Fall below them and your campaign won't go live. Here's every number you need and how to apply them.
Campaign-Level Budget Minimum
What is the $50 campaign minimum
Per TikTok's Business Help Center, every campaign requires a minimum daily budget of $50 USD. This is a hard floor. TikTok blocks any campaign submitted below this amount before it even reaches review.
The $50 represents total campaign spend per day. It acts as a ceiling that distributes across all ad groups underneath it.
When it applies and what it covers
The campaign minimum applies whether you use Campaign Budget Optimization (CBO) or not. With CBO on, all ad groups share the $50 pool. TikTok's algorithm allocates spend across ad groups automatically based on performance signals.
Without CBO, each ad group controls its own budget. The campaign minimum still applies as an overarching cap on total daily spend.
Ad Group-Level Budget Minimum
The $20 daily ad group floor
Every ad group requires a daily budget above $20 USD. Per TikTok Ads Manager documentation, this is a strict minimum. A $20.01 budget clears the threshold. A flat $20.00 does not.
Regional variations for conversion campaigns
Web conversion campaigns carry a higher recommended floor in some markets. TikTok's Budget and Bidding FAQ states $30/day for North America and EMEA brands. APAC brands stay at the $20 floor. Check your account's billing region to confirm which applies to you.
Calculating Lifetime Budget Minimums
Formula: $20 × scheduled days
Lifetime budgets follow a straightforward formula. Take the $20 daily minimum and multiply by the total number of days your campaign runs.
Minimum lifetime budget = $20 × scheduled days
Example: 31-day campaign lifetime budget
A full-month campaign needs at least $620. That's $20 × 31. TikTok rejects any lifetime budget below this calculated floor at submission. Always run the formula before setting a fixed total.
Daily vs. Lifetime Budget: Which to Use
TikTok's recommendation for daily budgets
TikTok's budget best practices documentation recommends daily budgets for ad groups. Daily budgets give the algorithm more flexibility to optimize delivery day over day. They also make it easier to adjust spend without disrupting campaign performance.
When lifetime budgets make sense
Lifetime budgets fit time-bound promotions with a fixed total spend. A 7-day product launch where you need hard cost control is a good fit. Outside of fixed-window scenarios, daily budgets give you more room to react and optimize.
Setting Your Initial Budget Beyond the Minimum
10x CPA rule for learning phase success
The minimums get your campaign live. They don't guarantee the algorithm learns fast enough to perform. Per TikTok's bidding best practices, set your daily budget to 10× your average daily CPA from the prior 7 days. This gives TikTok enough conversion data to exit the learning phase and stabilize delivery.
Safe budget increase guidelines
Once your campaign is live, increase spend carefully. TikTok's documentation states: raise your daily budget by no more than 40% per adjustment. Larger jumps reset the learning phase and spike your CPA while the algorithm recalibrates.

Frequently Asked Questions
What happens if I set a TikTok ad budget below the minimum?
TikTok blocks the campaign at submission. You'll see an error and the campaign won't go live until you raise the budget to at least $50 at campaign level and $20 at ad group level.
How do I calculate a minimum lifetime budget for TikTok ads?
Multiply $20 by the number of days your campaign is scheduled to run. A 14-day campaign needs at least $280. A 31-day campaign needs at least $620.
Can I change my TikTok ad budget after a campaign is already live?
Yes. You can edit a live campaign or ad group budget. Keep increases to 40% or less per adjustment to avoid resetting the learning phase and spiking your CPA.
Does the $20 ad group minimum apply to all campaign types?
The $20/day floor applies broadly. For web conversion campaigns, TikTok recommends raising that to $30/day if you're targeting audiences in North America or EMEA.
