Google is rolling out a significant update to how average daily budgets pace in campaigns that use ad scheduling — and it could materially change monthly spend totals.
What’s happening. Starting March 1, 2026, Google Ads will begin proactively pacing budgets to spend up to the full 30.4x monthly limit, even if campaigns only run on specific days via ad scheduling.
How it works:
- The 2x daily overspend rule stays in place.
- The 30.4x average daily budget monthly cap remains unchanged.
- Campaigns will not run outside scheduled hours.
- But Google will now attempt to hit the full monthly ceiling within the allowed schedule.
Why we care. Until now, advertisers running limited schedules — like weekends only — effectively spent less per month because Google paced against active days. Campaigns using ad scheduling may start spending significantly more per month — even though daily budgets and billing caps haven’t changed.
Google will now push harder to hit the full 30.4x monthly limit within scheduled days, which could double spend for weekend-only or limited-hour campaigns. Without adjusting daily budgets, marketers risk unintentionally overshooting their intended monthly targets.
Example. A campaign set to weekends only with a $100 daily budget previously spent about $800/month (roughly eight weekend days).
Under the new pacing logic, it could spend up to $1,600/month — hitting $200 (2x daily budget) on each scheduled day.
What Google says. According to Google Ads Liaison Ginny Marvin, the goal is to better align pacing behavior with advertisers’ expectations around monthly spend limits. Spend will still be driven by campaign objectives like conversions or conversion value, and no campaign will exceed the existing billing caps.
Ginny also clarified that only advertisers who received notifications about this update will be affected and the change will be slowly rolled out.
Between the lines. This is less about raising limits — and more about how aggressively Google uses existing ones. For advertisers relying on ad scheduling to naturally suppress spend, this could lead to unexpected increases unless daily budgets are recalibrated.
What to do now:
- Review campaigns using ad scheduling.
- Recalculate daily budgets based on true monthly goals.
- Lower daily budgets if you want to maintain previous monthly spend levels.
The bottom line. Google isn’t changing how much you can spend — it’s changing how quickly you will spend it. Flighted and part-time campaigns should adjust before March 2026.
