Daily budget is the average amount a campaign or ad set can spend in a day. Platforms use that figure flexibly across days: they go over it on days they see opportunity and stay under it on weak days, pulling the average toward the target. That is why decisions are not made by looking at a single day's spend.
What really matters about the budget level is its relationship with the learning phase: if the ad set runs on a budget too low to produce enough weekly conversions, the algorithm cannot optimize and cost stays volatile. The practical calculation runs backwards; multiply the target cost per acquisition by the conversions needed per week and divide by seven. Sudden, large budget increases reset learning, while gradual increases preserve performance. The same money split across many sets almost always performs worse than concentrated in one.
Required daily budget ≈ (Weekly target conversions × Target CPA) ÷ 7
For 50 conversions a week at a 60 TL target cost per acquisition, the required daily budget is (50 × 60) ÷ 7 ≈ 430 TL.
