Set a budget for your campaign

If you've ever planned a holiday, you know the importance of setting a limit for how much you can spend while allowing for the unexpected. In the same way, AdWords lets you set daily budgets for your campaigns with the flexibility to change them at any time.

Decide how much to spend

With AdWords, you choose a daily budget for each campaign based on your advertising goals and the general amount that you're comfortable spending each day.


Let's say that your cost-per-click is £0.10 on average, and you'd like around 100 clicks per day. You might budget £10 per day.

Using this example, here's how you'd work out your daily budget:

£0.10 x 100 = £10 per day (Cost-per-click x Clicks per day = Daily budget)

If you're used to working with a monthly advertising budget, you can calculate the amount that you might budget per day by dividing your monthly budget by 30.4 – the average number of days per month.


Let's say that you normally spend £304 per month on advertising. To work out your daily budget, you'd divide £304 by 30.4 and would get a daily budget of £10.

Using this example, here's how you'd work out your daily budget:

304 / 30.4 = £10 per day (Monthly budget / Average number of days per month = Daily budget)

You can also create shared budgets, which let you allocate budget across multiple campaigns.

Set your daily budget

Your daily budget applies to a single campaign, not all campaigns in your account. Here's how to set your daily budget for a new campaign:

  1. Sign in to your AdWords account at
  2. Click the Campaigns tab.
  3. Click + Campaign and select the campaign type that you'd like to create:
    • "Search Network with Display Select"
    • "Search Network only"
    • "Display Network only"
  4. On the "Select campaign settings" page, scroll to the "Budget" section and enter an individual daily budget or use a shared budget. Set a budget
  5. Finish (or skip) choosing your other campaign settings and click Save and continue.


  • Get a recommendation. AdWords shows recommended budgets for campaigns that repeatedly meet their daily budget but have the potential to earn more clicks and impressions. Learn how to find your recommended daily budget.
  • Don't set and forget. Check your account regularly to look for campaigns that are limited by budget or have leftover pounds. A limited budget could mean fewer clicks and impressions than you might have otherwise earned, whereas a bloated budget may actually increase the cost per click of your ads if you're using automatic bidding. You can check the Status column on your Campaigns tab to see whether any of your campaigns show a "Limited by budget" status.

How budget changes take effect

When you change your daily campaign budget you'll see these adjustments immediately in your account. Based on when you edit your budget, the way that your campaign consumes your budget can vary. Here's what happens to your budget based on the time or frequency of your change:


Campaigns will typically spend around 50% of their budget in the day's first half and the remainder in the day's second half. However, if demand for your ads happens to be greatest early in the day, you might spend 70% of your daily budget in the morning.

If you made a budget change around noon, you might spend an additional 50% of your new daily budget in the afternoon, which could result in a total spend for the day which is slightly greater than either of the daily budgets which were in effect that day. This results from the fact that the system is designed to make up for low traffic days by slightly exceeding your daily budget on higher traffic days, as long we never exceed your monthly charging limit.

If you've lowered your daily budget significantly, it's also possible that your ad distribution will slow significantly for the rest of the day.

Multiple times a day

You'll be charged based on the highest daily budget that you chose for that day.


You'll be charged for the month no more than the new budget multiplied by the number of days that remain in the month plus the total amount spent for the campaign before the budget change.

For example, if on 24 November your daily budget is £5, and you've already spent £113 this month, and on the same day you change your daily budget to £10, you'd be charged no more than as follows:

£113 spent so far + (£10/day X 7 days remaining) = £183

Multiple times a month

The same calculation applies as the one for changing your budget mid-month.


Even if you don't deliberately change your daily campaign budget, the following actions are considered budget changes (for computing the maximum amount that you'll be charged within a calendar month):
  • Changing your campaign end date.
  • Changing your delivery mode (standard delivery or accelerated delivery).
  • Choosing a different time zone for your AdWords account.
