Google changed how daily budgets pace. What it means for your monthly spend.
TL;DR
Google changed how it paces daily budgets on 1 June 2026. Scheduled campaigns now pace toward the full monthly limit, so monthly spend can rise unless you lower your daily budgets. Here's the maths to hold your number.
On 1 June 2026, Google changed the way Google Ads paces daily budgets. The daily and monthly caps are the same as before. What changed is how hard Google pushes to spend, and for campaigns on an ad schedule it can mean a noticeably bigger monthly total.
If you run your campaigns every day at a steady budget, the effect is small. If you use ad scheduling, running only on weekdays, or only during office hours, this one is worth ten minutes of your time.
What actually changed
Google Ads has always worked to two limits: it won't spend more than twice your daily budget on any single day, and it won't spend more than 30.4 times your daily budget in a month. Those limits still hold.
The change is in the pacing between them. Before 1 June, if your ads were only eligible to run on certain days, Google paced your spend across those days. A weekday-only campaign aimed to spend its daily budget across roughly 22 weekdays, not the full month. After 1 June, Google paces toward the full monthly amount, 30.4 times your daily budget, regardless of how many days your schedule allows. On the days your ads do run, it spends harder to reach that monthly figure.
So the daily budget number on your screen now implies a higher monthly total than it used to, if you run anything other than an all-day, every-day schedule.
What it does to your spend
Take a campaign set at £100 a day, scheduled for weekdays only. Under the old pacing, that came out around £2,100 across a month. Under the new pacing it works toward the full monthly limit, closer to £3,040. The setting you chose hasn't changed. The amount it spends has.
For a single small campaign that might be a welcome bit of extra reach. Across an account with several scheduled campaigns and a fixed monthly budget, it adds up to an overshoot you didn't plan for.
How to hold your monthly number
If your goal is a set monthly spend, the fix is to bring daily budgets down so the new pacing lands where you want it.
For a clean start, Google's own arithmetic is the simplest version: new daily budget = your current daily budget, times the days you actually run per month, divided by 30.4. A £100 weekday-only budget comes down to about £72 to hold the same monthly total.
Partway through a month, when some of the budget is already spent, a run-rate calculation is more accurate:
- Start with your monthly target.
- Subtract what you've already spent this month, at campaign level, using verified figures rather than estimates.
- Divide what's left by the days remaining. That's your required daily run-rate.
- Compare it to the sum of your current daily budgets. If the current total is higher, you're on course to overshoot.
- Bring each campaign's daily budget down in proportion to how it's been spending, so the cut falls where the money is actually going.
A worked example. Say you're targeting £16,000 for the month. Nine days in, you've spent £4,574, which leaves £11,425 across the 21 remaining days, a run-rate of £544 a day. If your current daily budgets sum to £633 a day, you're tracking to roughly £17,900 by month end, about £1,900 over. Lowering daily budgets to hit the £544 run-rate, weighted by each campaign's recent spend, brings the month back to target.
Scheduled campaigns need handling separately. They're the ones the June change affects, so they're usually where the heaviest reductions belong. A campaign that runs all day, every day, needs little adjustment. A weekday-only or office-hours campaign needs more.
Monthly control is now ongoing work
The pacing change is permanent, so monthly spend is something to manage through the month rather than set once and forget. A daily budget that produces the monthly total you want, revisited as spend comes in, is the steady-state habit.
For an account with several scheduled campaigns, that recalculation is the fiddly part. It's the work Addy does: it reads your verified campaign-level spend, works out the run-rate to your target across the days left, and proposes new per-campaign budgets, with the full working shown before anything changes.
How far Google takes this is the open question. Pacing has been moving toward fuller budget use, and monthly control increasingly sits with the advertiser rather than the platform's defaults. For this month, the practical step is to look at any campaign on a schedule and check where its spend is now heading.
