Daily Budget

What is ?

A daily budget is the average amount you are willing to spend per day on an ad set or campaign. Meta may spend up to 25% more than your daily budget on high-opportunity days and less on slower days, but your weekly average will not exceed your daily budget multiplied by 7. Daily budgets offer flexibility and are recommended for ongoing campaigns where you want consistent daily delivery.

Formula

Weekly Spend Limit = Daily Budget × 7

Example

You set a $50/day daily budget on an ad set. On a high-performance Tuesday, Meta spends $62.50 (25% over). On a slow Sunday, it spends only $38. Over the full week, total spend does not exceed $350 ($50 × 7). This flexibility lets Meta capitalize on good opportunities.

Optimization Tips

  1. 1

    Set your daily budget to at least 10x your expected CPA to give Meta enough room to exit the learning phase within a week.

  2. 2

    Use daily budgets for always-on campaigns and switch to lifetime budgets only for time-limited promotions.

  3. 3

    When scaling, increase daily budgets by no more than 20% every 3–5 days to avoid resetting the learning phase.

  4. 4

    Monitor overspend days: Meta can spend up to 25% more than your daily budget on any given day.
