About Smart+ Auto Budget Increase (Cost Cap/Minimum ROAS/Target ROAS)
The auto budget increase setting automatically raises your daily budget when certain conditions are met. This helps goal-based bidding campaigns (Target ROAS and Cost Cap) scale more efficiently, without requiring constant manual adjustments.
Note: The Auto Budget Toggle is not available to all advertisers at this time.
Benefits

You can toggle it off at anytime. - For existing campaigns, the toggle will be switched off by default. |
How it works
Your daily budget will increase when both of these conditions are met:
Performance condition
Cost Cap campaigns or ad groups: Actual Cost Per Acquisition (CPA) is within the Cost Cap bid.
Minimum ROAS or Target ROAS: Actual ROAS meets or exceeds the your ROAS bid.
Budget condition
At least 90% of the daily budget is spent.
Note: Low budgets may limit scaling and campaign delivery.
When both conditions are met, the system will automatically increase the daily budget by 20% of the original budget.
The budget can increase up to 10 times per day.
Each increment equals 20% of the original budget.
At the start of the next day, the budget resets to the last manual input.
If the conditions are met again, auto increases will continue.
Example:
Calculation | New Budget | ||
Day 1 | Original Budget | - | $50 |
1st increase | $50 + (20% * $50) | $60 | |
2nd increase | $60 + (20% * $50) | $70 | |
3rd increase | $70 + (20% * $50) | $80 | |
... | ... | ... | |
10th increase | $140 * (20% * $50) | $150 | |
Day 2 | Reset to Original Budget | - | $50 |
1st increase | $50 + (20% * $50) | $60 | |
