Daily Budget Calculator
A Daily Budget Calculator helps you determine how much you should spend per day based on your total monthly advertising budget.
This method is simple and practical for Google Ads campaign planning.
Daily Budget Formula
Daily Budget = Monthly Budget ÷ 30.5
(30.5 represents the average number of days in a month.)
Example Calculation
If:
Monthly Budget = $3,050
Then:
Daily Budget = 3,050 ÷ 30.5
Daily Budget = $100
This means you should set your Google Ads daily budget to $100.
Why Use 30.5 Days?
Months vary between 28–31 days.
Using 30.5 gives you a balanced daily budget across the entire year and prevents overspending.
Why This Matters in Google Ads
Google Ads may spend slightly more than your daily budget on certain days but balances it over the month.
Setting the correct daily budget ensures:
• You stay within your monthly spending limit
• Campaigns run consistently
• Budget pacing remains stable
