At a glance
Pacing check, comparing actual TikTok spend in the period against the configured budget cap, expressed as a percentage. Especially important on TikTok, because Campaign Budget Optimisation (CBO) treats daily budgets as targets rather than hard ceilings and can overshoot 20, 30% on viral creative. The card fires when you’ve burned >90% of the budget before 80% of the period elapsed.
Calculation
Calculated automatically from your TikTok Ads data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.Worked example
A US Gen-Z DTC athleisure brand running a 30-day TikTok push tied to a product-launch flight 02 Apr 26 to 01 May 26. Account currency USD. Configured monthly budget cap (Billing > Spending Limit): 1,300 / day target.
What’s happening:
- Days 14, 21 saw a creative go viral. Cold-prospect In-Feed creative #4 (a UGC-style “first-impression unboxing”) hit a 4.8% CTR on day 13, up from 1.2% baseline. CBO responded by allocating 70% of daily budget to that single ad. Daily spend ran at 2,200 (vs $1,300 target) for 7 consecutive days.
- By day 23 the alert fires. 40,000 monthly cap = 95.5% used; 23 of 30 days elapsed = 77% of period. Classic >90%-before-80% trigger.
- Three options at this point:
- Pause and replan. Saves $1,800 but kills momentum on a winning creative; CTR will drop when re-launched as the algorithm re-learns. Cost: 7, 14 days of re-learn.
- Raise the monthly cap. Quick decision; the unit economics on this creative are solid (ROAS 4.6x, well above the 2.5x business floor). Going from 50k preserves momentum and captures the rest of the viral window.
- Tighten the per-campaign daily budget. Cap CBO’s overshoot ability. Less responsive to viral signal but predictable.
- Most-common right answer: option 2 (raise the cap). Viral creative on TikTok is rare; budget caps should be elastic when ROAS is well above floor. The monthly-cap discipline matters when ROAS is below floor, not above it.
- Avoid going lifetime budget mode mid-flight. Switching
BUDGET_MODE_DAILYtoBUDGET_MODE_TOTALon a campaign mid-period resets the optimiser’s pacing logic and drops delivery for 24, 48 hours. Don’t reach for this lever in the middle of a winning flight.
- 80% used at 80% of period = on pace, healthy.
- 95% used at 70% of period = aggressive pacing, decide whether to raise cap or throttle.
- 50% used at 80% of period = under-pacing, why? Often a delivery throttle (creative rejected, audience too narrow) rather than a savings.
- 100% used at 50% of period = budget runaway, almost always a CBO overshoot on viral creative. Decide quickly.
- 100% used at 100% of period = perfect pacing, rare in practice on TikTok.

Reconciling against the vendor’s own dashboard
Where to look in TikTok Ads Manager: TikTok Ads Manager > Campaign > Budget column + Cost column. Sum the campaign budgets and divide cost. For account-level cap pacing, Billing > Spending Limit shows the configured monthly cap and progress bar. Other Ads Manager views:- Pacing Insights (per-campaign). TikTok’s own per-campaign pacing forecast. Useful for predicting whether the campaign will deliver in full by end-date.
- Delivery > Learning Phase. Adsets in Learning often spend without delivering against budget targets. Different cause, similar pacing read.

Known limitations / merchant FAQs
Why does TikTok overshoot my daily budget? Campaign Budget Optimisation (CBO) treats daily budgets as targets, not hard ceilings. When the algorithm finds a winning creative, it overspends 20, 30% in a single day to capture the auction window. Lifetime budgets are honoured strictly; daily caps are pacing guidance. If you need a hard ceiling, use a lifetime budget on a date-bounded campaign or set a daily account-level cap in Billing > Spending Limit. TikTok says I’m at 95% used at 70% of period; should I pause or raise the cap? Decision tree:- Check ROAS first. ROAS above your business floor (typically 2.5x for DTC after COGS) and well above 1.0x: raise the cap, capture the rest of the viral window.
- ROAS below floor: pause. The overshoot is not earning out, you’re feeding a bad spend curve.
- ROAS at floor: cap and re-plan. Don’t add fuel; don’t kill momentum either.
- Raise the limit in Billing > Spending Limit (instant, but takes 5, 30 minutes for campaigns to resume serving).
- Investigate the overshoot before re-launching. Was it CBO viral response (good problem) or auction inflation (bad)? Check Spend Anomaly and CPC Trend.
- Re-pace going forward. After a budget hit, the algorithm goes back into a mini-Learning Phase as it re-balances. Expect 24, 48 hours of slightly lower delivery efficiency.
- Creative rejected. Some creatives get content-flagged 24, 72h after launch (not on submission). When that happens, delivery drops, pacing falls.
- Audience too narrow. Lookalikes <1% or interest-based audiences with <500k reach often hit a delivery ceiling.
- CPC inflated past the bid cap. If CPC rises past your bid cap, TikTok will scale delivery down rather than overshoot the bid.
