When you create an ad campaign or an ad group, you can choose how you want to pay for it by choosing your budget preferences. Your budget is the total amount of money you want to spend to run your ads. While bidding options help you control the cost per result at the ad level, your budget determines the overall cost for your campaigns and ad groups.

You can set a budget for your ad campaigns and ad groups. There are two types of budgets you can choose:

• Lifetime budget: Choose the maximum amount you are willing to spend on a campaign or ad group during its entire run time. Learn more about lifetime budgets.

• Daily budget: Choose the maximum amount you are willing to spend on a campaign or ad group per day. Learn more about daily budgets.

Minimum budgets

A minimum budget is required for both lifetime budgets and daily budgets in order to ensure the continuous delivery of your ad. You can set a minimum budget at the campaign or ad group level:

• Campaign level minimum budget: For campaigns, both daily budgets and total budgets must exceed 50 USD.

• Ad group level minimum budget: For ad groups, daily budgets must exceed 20 USD. Lifetime budgets will be calculated as the minimum daily budget (20 USD) × scheduled days.

For example: If delivery is scheduled for 31 days, the minimum budget for the ad group would be 20 USD × 31 days = 620 USD.
