Daily budgets significantly impact the success of Google Ads campaigns. This article delves into the mechanics of Google Ads daily budgets and provides insights on determining the ideal daily spend to achieve your advertising goals.
What is a Daily Budget in Google Ads?

A Google Ads daily budget is the average amount you’re willing to spend daily on a specific campaign. Google uses this budget to control ad spend and ensure you don’t exceed your monthly advertising budget.
How Does Your Google Ads Daily Budget Work?
Google Ads serves ads based on your daily budget, determining how often your ads appear throughout the day. Use this formula to calculate your Google Ads daily budget:

Daily Budget = Monthly Budget ÷ 30.4
Alternatively, some advertisers use this formula to determine their monthly budget:
Monthly Budget = Daily Budget × 30.4
For example, with a $10 daily budget, Google will show your ads until clicks or impressions consume $10. Once reached, ads typically stop showing for the remainder of the day.

Note that Google may exceed your daily budget by up to 20% on some days due to traffic fluctuations. However, Google guarantees not to exceed your monthly spending limit, which is the average number of days per month (30.4) multiplied by your average daily budget.
Why is Daily Budget Crucial?
