How does budget auto-rollover work?

Last updated: October 7, 2026

If a campaign underspends during its ramp-up, auto-rollover carries part of the unspent budget over to the following week. This gives the campaign a chance to catch up on spend without you changing its budget.

How it works

  • A campaign must underspend by more than 10% to earn rollover. Small differences don't trigger it.

  • Rollover is capped at 20% of the monthly budget per week and doesn't add up across weeks.

  • If a campaign catches up (reaches 90% or more of its weekly target), its rollover resets to zero the following Tuesday.

  • Editing a campaign's monthly budget resets its rollover to zero. The new amount becomes the baseline.

The change takes effect immediately. If your campaigns underspent the previous week, you'll see the higher budgets within seconds.

A budget increase on a live campaign with Cross-channel or Image display ads can put it into re-learning. Your ads keep delivering. See How does campaign Learning work?

Where you see it

On the Campaigns page, campaigns with rollover show their original monthly budget plus a green (+amount) badge. Hover over the badge to see the breakdown. In the campaign settings, a banner below the Monthly budget field reads: "Auto-rollover active: Original $X + $Y rollover = $Z effective."
