Google Ads Spending More Than Your Daily Budget? What Changed on June 1, 2026

Why This Post

Over the past few days, several clients have contacted me with the same question: “My daily budget is 20 euros, but Google Ads is suddenly spending 30 or even 40 euros per day. Is this a bug?”

The short answer: no, it is not a bug. On June 1, 2026, Google changed the logic it uses to distribute daily budgets across the month. The change primarily affects campaigns with ad scheduling, meaning campaigns that only run on certain days or at certain hours. The change is official, well documented, and affects a large number of accounts. In this post I explain exactly what happened, show the impact using real numbers from a client account, and give concrete recommendations for setting your budgets going forward.

The Daily Budget Was Never a Hard Limit

For context: the daily budget in Google Ads has always been an average, not a daily cap. Two rules have applied for years and continue to apply:

On individual days, Google may spend up to twice your daily budget. With a 20 euro daily budget, days of up to 40 euros are possible.
Per billing month, Google may charge at most 30.4 times your daily budget. With 20 euros, that is 608 euros. If delivery exceeds that, Google automatically credits the difference as overdelivery costs.

Neither of these two caps has changed. What changed is how aggressively Google uses them.

What Changed on June 1, 2026

Until the end of May, Google paced spending based on the days your ads actually ran. An example: a campaign with a 20 euro daily budget that runs weekdays only via ad scheduling had around 22 active days per month. Google spread the budget across those 22 days, so monthly spend landed at roughly 440 euros.

Since June 1, 2026, Google paces toward the full monthly cap regardless of how many days the campaign is active. The same campaign now targets 20 euros × 30.4 = 608 euros per month, compressed into just 22 active days. That averages out to roughly 27.60 euros per weekday, and noticeably more on strong days. Ads still run exclusively within the scheduled windows. But within those windows, spending is significantly higher.

Google announced the change in February 2026, originally planned it for March 1, and then postponed it to June 1. The rollout is gradual, and affected advertisers were notified in their accounts. Google Ads Liaison Ginny Marvin confirmed the change publicly:

“Spend will still be driven by campaign objectives and no campaign will exceed existing billing caps.” (Ginny Marvin, Google Ads Liaison)

Search Engine Land summed up the shift well: budget pacing is becoming less about when ads run and more about ensuring the full budget gets spent.

What This Looks Like in a Real Account

Numbers from a client account I manage show the break exactly on the effective date. The campaign has a 20 euro daily budget and runs Monday through Friday only via ad scheduling:

Period	Daily spend
May 28 and 29	19.14 € and 19.21 €, cleanly under budget
June 1 to 10	22.20 € / 29.58 € / 29.10 € / 17.85 € / 29.54 € / 36.39 € / 28.44 € / 28.49 €

Before June 1, every day stayed under 20 euros. Since June 1, almost every weekday is above it, averaging 27.70 euros. Projected across 22 weekdays, that is around 609 euros per month, almost exactly the monthly cap of 608 euros. Google is not roughly approaching the new quota, it is hitting it precisely.

Who Is Affected

All campaigns using ad scheduling are affected, meaning campaigns that do not run around the clock on all days. The stronger the restriction, the bigger the effect: a weekend-only campaign can nearly double its monthly spend. Campaigns without a schedule behave as before. The effect is most pronounced for campaigns flagged as “Limited by budget” and for uncapped Smart Bidding strategies like Maximize Conversions, because these use every opportunity to spend the available quota.

Best Practices: How to Proceed

1. Recalculate your daily budget. This is the most important step. Stop calculating with active days and use this formula instead: desired monthly budget divided by 30.4. Example: you want to spend 20 euros on each of 22 weekdays, so 440 euros per month. Set 440 ÷ 30.4 = roughly 14.50 euros as your daily budget. Individual days will still fluctuate, but the monthly total lands on target. This calculation also matches the approach confirmed by Google.

2. Use total budgets for hard caps. In early 2026, Google expanded fixed total budgets for periods of 3 to 90 days. Unlike the daily budget, they are a hard limit that cannot be exceeded. For promotions, test runs, or accounts with a fixed monthly budget, they are the more reliable control.

3. Set up automated rules and alerts. Create rules in your account that notify you when you reach, for example, 75 and 90 percent of your monthly target. That way you catch deviations before they get expensive. I advise against daily pause rules, however, as they interfere with Smart Bidding.

4. Watch the monthly total, not individual days. The relevant control metric is your billing summary, not a single day. As long as the month stays below 30.4 times the daily budget, everything is within the rules. If it exceeds that, the difference is credited automatically.

5. Review budget-limited campaigns. Campaigns flagged as “Limited by budget” exploit the new quota the most. Check first whether the budget matches your actual goals, and adjust it using the formula from point 1.

Conclusion

The confusion is justified, because Google fundamentally changed how daily budgets behave after many years. It is not a bug, and you will still never be billed more than 30.4 times your daily budget per month. But if you use ad scheduling and have been calculating your budget per active day, you have been spending more real money since June 1, 2026 than before. The fix is unspectacular: recalculate your daily budget once, set up alerts, and keep an eye on the monthly total.

If you are unsure how the change affects your account, I am happy to take a look. As a Google Ads freelancer, I manage accounts from small local budgets to five-figure monthly spends. And if you are weighing paid ads against organic visibility, I compared the two in Google Ads or SEO.
