Set a budget for your campaign
AdWords uses daily budgets—if you’re working with a monthly budget, just divide that figure by 30.4 (the average number of days in a month). AdWords aims to show your ads until your daily budget is met (except in cases of overdelivery), and you pay only when someone clicks your ad. Learn more about Charges and your daily budget.
