Google changed how it spends your budget on June 1.
If your Google Ads spend looks higher this month and nobody touched anything, nobody did. The pacing model changed on June 1, and most accounts won’t get a heads-up about it.
I spent part of this week re-calibrating my own monitoring because of it, so let me save you the surprise.
Almost everyone treats their daily budget as a daily cap. It isn’t, and it never was. It’s an input into a monthly formula, and Google has always been allowed to spend more than your daily number on any given day, as long as the month evens out.
The old math went like this. On any single day, Google could spend up to twice your daily budget. Over a full month it capped things at your daily budget times 30.4 (that’s the average number of days in a month). So a €10/day campaign could hit €20 on a busy Tuesday, but it would never cross roughly €304 across the month.
The wrinkle was ad scheduling. If you ran a campaign on weekdays only, Google paced it over the active days, so that same €10/day campaign quietly landed around €220 for the month instead of €304. Twenty-two active days, roughly ten euros each. Predictable, once you knew to expect it.
That’s the part that changed
From June 1, the monthly ceiling becomes a flat 30.4 times your daily budget, no matter how many days the campaign actually runs. The weekday-only €10/day campaign that used to settle around €220 can now spend the full €304 across those same 22 days. Same budget number on the screen, about 38% more per active day.
The tighter your schedule, the bigger the jump. A campaign that only runs two days a week (a weekend promo, a short daypart) can see up to double the spend per active day it used to. Campaigns running all seven days won’t notice a thing, the formula was already the same for them.
None of this is a runaway, and it isn’t a bug. It’s a different pacing model, and the people who’ll feel it are the ones running schedules, which in lead-gen is most of us.
So, two things worth doing.
First, if you watch spend with any kind of alert, stop anchoring it on “today went over twice the daily budget.” After June 1 that check fires on every scheduled campaign for no real reason. Anchor on the rolling monthly number against your actual monthly cap instead, that’s the figure that still means something.
Second, if you’ve got clients on dayparted or weekday-only campaigns, tell them now, before the invoice does. “Google spent more and you changed nothing” is a fair thing for a client to be annoyed about when it lands as a surprise, and it’s a much easier conversation a week early than a week late.
The budget number you type in hasn’t changed. What Google does with it has. Worth a five-minute look at anything you’ve got on a schedule before the month really gets going.
