What it measures
A Google Ads budget is the monthly and daily spend required to buy a target number of clicks at your average cost per click.
Formula
Monthly budget = Target clicks × CPC · Daily budget = Monthly budget ÷ 30.4
Worked example
To get 1,500 clicks a month at a $2.50 CPC, you need a $3,750 monthly budget, or about $123.36 per day.
Typical benchmarks
- Days used per month
- 30.4
- Daily overspend cap
- Up to 2×
- Typical SMB monthly budget
- $1,000-$10,000
How this calculator works
Monthly budget = target clicks × CPC. Daily budget = monthly budget ÷ 30.4. Google may spend up to 2× your daily budget on high-traffic days but won't exceed your monthly equivalent.
Frequently asked questions
How do I set a Google Ads budget? +
Work backwards from your goals: estimate the clicks you need to hit your conversion target, multiply by CPC, and divide by 30.4 for a daily cap.
Can Google overspend my daily budget? +
On a given day it can spend up to twice your daily cap, but over a month it won't exceed your daily budget × 30.4.
Should I use a daily or monthly budget in Google Ads? +
You set a daily average budget per campaign; Google multiplies it by 30.4 to derive your monthly spending limit. Shared and campaign-total budgets are also available for certain campaign types.
How do I split my budget across campaigns? +
Allocate more to your highest-intent, best-converting campaigns and cap experimental or broad-reach campaigns. A common starting split is 70% proven, 20% scaling, 10% testing.
Can I change my Google Ads budget at any time? +
Yes. Budgets can be edited anytime and take effect immediately, though Smart Bidding may briefly re-enter a learning period after large changes.
