Google is quietly increasing your monthly budget

How it used to work, and why you trusted it

When you use Google Ads, you set a daily budget. That daily budget is the amount Google is allowed to spend per day. However, Google has been honest about one thing for years: on busy days, it can spend up to twice your daily budget if there's a reason for it. The promise was that this would balance out over the course of the month.

To guarantee this, Google used a monthly cap. This cap protected you from unlimited overspending. And the calculation was simple: the number of days in the month that your ads actually ran, multiplied by your daily budget. If you use ad scheduling and only run on weekdays, Google only counted those active days. So you were protected by your own settings.

For many tradespeople, that was a conscious choice. A painter who doesn't answer their phone at the weekend also doesn't want to attract customers on Saturdays. So you set your adverts to a weekday schedule. Smart, well organised. And you knew what the maximum monthly cost could be.

What's on 1 June changed

On 1 June 2026, Google adjusted the calculation of the monthly cap. From that date, the monthly cap will always be 30.4 times your daily budget, regardless of how many days your ads actually run. Whether you advertise 5 days a week, 3 days a week, or even just on Tuesday mornings.

This might sound technical, but the consequences are very concrete. Google acknowledges in its own documentation that your daily budget is designed to average out over time. However, the protection you had through scheduling is now different. The monthly cap no longer depends on your active days, but on the fixed factor 30.4. This is the average number of days in a calendar month.

In practice, this means that if you advertise only a few days a week, your monthly budget limit is now higher than you would expect based on your schedule. And if Google decides to spend significantly more on those active days (which it is allowed to do, up to twice your daily budget), then there is suddenly much more room to do so than before.

The sum that hurts

Let's make it concrete with an example that many of TheSEO's clients will recognise. You're a handyman in Tilburg. You're running Google Ads with a daily budget of €100. You only advertise on weekdays, as you don't want to take calls at the weekend.

In a 30-day month, there are on average 22 working days. Your monthly ceiling was therefore £100 x 22 = £2,200. You knew this, you had factored it in, and this allowed you to forecast your monthly marketing costs to your accountant.

From 1 June 2026, your monthly cap will be €100 × 30.4 = €3,040. That's €840 more than was previously possible. And if Google spends €200 per day on your busiest days (which falls within the daily limits), that cap will fill up faster than you expect.

This doesn't mean that Google will actually spend €3,040. If there's low search volume, it will spend less. But the ceiling has now definitely been raised. And in a busy month, with good search volume, that gap can close without you even noticing.

• Old ceiling (Weekdays, €100/day): €2,200 per month
• New ceiling (always 30.4x, €100/day): €3,040 per month
• Difference£840 per month extra possible

For a gardener with a tight seasonal budget or a painter closely monitoring costs, that's not a small difference. It's an extra week of advertising per month that has suddenly become possible.

Who does this concrete comes into contact

Not every advertiser will notice this change. If you advertise daily, seven days a week, your monthly cap was already 30.4 times your daily budget. In theory, nothing changes for you.

However, for most local tradespeople we know, it looks different. A plumber only advertises on weekdays because they are unavailable on weekends. A paving contractor runs their campaign in winter when it's freezing. A roofer uses time scheduling to only run between 08:00 and 17:00. All those settings used to mean a lower monthly ceiling. Not anymore.

Specifically, the most affected situations are:

• You are using an ad schedule that is not active 7 days per week
• You have set schedules per day, for example only mornings
• You regularly pause campaigns but haven't set a fixed monthly limit through a budget strategy

If one of those points applies to you, it's worth laying out your current settings and your invoices from the last two months side by side. Not to panic, but to understand what the change means for your specific situation.

What you are now must do

The first step is simply to be aware of the situation. You're already doing that by reading this article. But awareness alone won't put a stop to your spending. Here are the steps you can take now.

Check your invoices for May and June. Compare the monthly expenses and see if there is an upward trend. If you spend noticeably more in June than in May while your campaign settings have not changed, budget pacing could be the cause.

Consider a shared monthly budget limit. Google Ads offers the ability to set a hard limit at the account or per-campaign level via campaign budgets with monthly caps. This is an explicit brake on top of the automatically calculated ceiling. If you want to be absolutely certain, set a hard limit.

Adjust your daily budget if you deem it necessary. If you still want to advertise on weekdays and limit your monthly budget to a certain amount, the simplest solution is to adjust your daily budget downwards. Do you want to spend a maximum of €2,200 per month? Then set your daily budget to €72 (€2,200 / 30.4). It's inconvenient that this is necessary, but it's the most reliable brake.

Take this with you on your next Google Ads check. Whether you manage your campaigns yourself or outsource them, this is a change that belongs in your periodic review. We are happy to help you review your current settings.
