Quick answer: TikTok has hard budget minimums and a formula-driven way to calculate your starting spend. Know the numbers, respect the learning phase, and scale in 50% steps. Ignore those rules and your budget gets wasted fast.

Understanding TikTok's Budget Minimums and Requirements
TikTok's minimums are non-negotiable. Know them before you spend a dollar.
Campaign-level vs. ad group-level budgets
TikTok lets you set budgets at two levels: campaign and ad group. The campaign budget caps total spend across all ad groups inside it. The ad group budget controls spend on one specific targeting set.
Campaign-level minimum daily budget: $50 USD.
Ad group-level minimum daily budget: $20 USD.
Both floors are enforced. TikTok will not let a campaign go live below these thresholds. There is no workaround.
Minimum daily spend by region and campaign type
Region matters too. North America and EMEA advertisers running web conversion campaigns need at least $30 per day at the ad group level. APAC advertisers can start at $20.
Per TikTok Ads Manager guidance, these minimums exist to give the algorithm enough data to optimize. Running below them usually means no meaningful delivery at all. Your campaign launches but goes nowhere.
Daily budget vs. lifetime budget: which to choose
TikTok recommends daily budgets for most small businesses. Daily budgets give the algorithm more flexibility to shift spend toward high-performing windows. Lifetime budgets distribute spend proportionally across your entire campaign window. That sounds predictable, but it constrains optimization, especially in the early days when performance is still volatile.
Stick to daily budgets when you are starting out.

How to Calculate Your Initial Budget Using TikTok's Formula
Pick a number based on what you want to achieve, not on what feels comfortable.
Using your target CPA to estimate budget needs
Your target CPA (cost per acquisition) is the anchor for everything. Decide what one conversion is worth to your business. Then multiply it according to TikTok's formula to arrive at your minimum daily budget.
Guessing a budget without a CPA target almost always leads to underspending and a campaign that never exits the learning phase.
Multipliers for different optimization objectives
Per TikTok's Business Help Center, the multipliers break down like this:
- Shallow conversions (add to cart, page views, video views): 50x your target CPA, with a $100 floor
- Deep conversions (purchases, lead form submissions): 10x your target CPA, with a $200 floor
- App installs: 20x your target CPA, with a $200 floor
Practical example: your target cost per purchase is $15. Ten times $15 is $150. The $200 floor applies, so your minimum daily budget is $200.
Practical example: your target CPA for a shallow conversion is $2. Fifty times $2 equals $100. Budget minimum is $100 per day.
Run the math for your own numbers before you set anything live.
Getting out of the learning phase: the 50-conversion benchmark
Budget directly determines whether your campaign can exit the learning phase. Aim for at least 25 to 50 conversions within the first 7 days. That requires enough daily budget to generate real data fast. Underfund the campaign and it stays stuck in learning, with unstable results and no useful signal.

The Learning Phase and Why It Matters for Small Businesses
The learning phase is TikTok's algorithm figuring out who should see your ads.
What happens during the learning phase
The algorithm tests audiences, placements, and delivery times. Performance during this window is often inconsistent. Cost per result can swing widely. That is normal behavior, not a sign the campaign is broken. Your only job is to hold steady and let it run.
Timeline: 7 days or 25 campaign results
The learning phase typically lasts about 7 days or until your campaign records 25 results, whichever comes first. TikTok Ads Manager shows you learning phase status inside the campaign dashboard.
Do not judge performance numbers during learning. Pausing early means you paid for data and threw it away.
Why budget stability matters during learning phase
Budget changes can reset or delay the learning phase. Any significant edit, including pausing and resuming, can push you back toward day one. Keep your budget flat for the full 7-day window and resist the urge to tweak. Stability is the only thing protecting your investment during this period.

Scaling Your Budget: The 50% Rule and Beyond
Once your campaign exits the learning phase, you have earned the right to scale. Do it carefully.
The 50% safe scaling zone
TikTok recommends keeping budget increases within 50% of the previous budget. Increase by more and you risk triggering a fresh learning phase. That means volatile performance again and more wasted spend rebuilding what you already had.
Doubling your budget overnight is tempting. It almost always costs more than it gains.
Timing your adjustments: waiting 2-3 days between changes
Wait at least 2 days between any budget changes. If you are using Campaign Budget Optimization, wait 3 days or 50 conversions before touching the budget again. Each adjustment needs time to settle before you can read the results accurately.
Using Smart+ automation to scale without manual work
TikTok's Smart+ Goal-Based Budget Increase handles scaling automatically. When your campaign meets its ROAS or CPA target and spends 90% of the daily budget, Smart+ raises the budget by 20%. It can trigger up to 10 times per day.
Smart+ resets to the original budget the next day, so you are not locked into a higher number permanently. One important constraint: Smart+ only works with goal-based bidding strategies like Target ROAS or Cost Cap. It is not available with Maximum Delivery.

Common Budgeting Mistakes Small Businesses Make
Most small business TikTok campaigns fail for the same three reasons.
Starting too small and not reaching learning phase
Running $5 a day on a purchase-optimized campaign generates nothing useful. You will not hit enough conversions to exit the learning phase. The algorithm cannot optimize. ROAS stays low. You blame the platform when the real problem is the budget. Spend enough to let the system actually work.
Making too many budget adjustments too quickly
Every budget change mid-flight costs you data. Adjust too frequently and you are constantly resetting the learning phase. Set your budget, let it run, then make one deliberate adjustment at a time.
Using lifetime budgets instead of daily budgets
Lifetime budgets feel safer because the total is capped. But TikTok cannot shift spend toward better-performing days as freely. Daily budgets are more flexible, more responsive, and generally perform better for conversion campaigns. Save lifetime budgets for short, fixed-window promotions with a hard end date.

Frequently Asked Questions
What is the minimum daily budget for TikTok ads?
TikTok requires a minimum of $50 per day at the campaign level and $20 per day at the ad group level. For web conversion campaigns in North America and EMEA, the ad group minimum rises to $30 per day. These floors are enforced and your campaign will not go live below them.
How long does the TikTok ads learning phase last?
The learning phase lasts approximately 7 days or until your campaign records 25 results, whichever comes first. Avoid pausing campaigns, changing budgets, or editing targeting during this window. Any major change can reset the phase and cost you the data you already paid for.
How much should I increase my TikTok ad budget when scaling?
TikTok recommends staying within 50% of your previous budget when scaling. For example, if your daily budget is $100, do not jump above $150 in one step. Larger increases risk triggering a new learning phase. Also wait at least 2 days (or 3 days and 50 conversions when using Campaign Budget Optimization) between adjustments.
Should I use daily or lifetime budget for TikTok ads?
TikTok recommends daily budgets for most small businesses. Daily budgets give the algorithm more flexibility to optimize across different times of day. Lifetime budgets distribute spend proportionally and limit that flexibility. Save lifetime budgets for short promotions with a fixed end date.
