Yes, several advertisers have noticed unexpected spikes or overcharges in their Meta ad spend recently. This can happen due to a few common reasons:
- Auto-scaling budgets or bid strategy changes — If you're using "Highest Volume" or cost cap bidding, Meta may overspend slightly to hit performance goals.
- Campaign or ad duplication — Accidentally duplicating high-budget ads or leaving older campaigns active can stack spend.
- CBO (Campaign Budget Optimization) — Meta may shift more budget to top-performing ad sets, which can drive up spend if not closely monitored.
- Billing cycle lag — Sometimes charges catch up late, making it look like you've overspent in a short window.
- Currency or tax misalignment — Especially if your billing account is set up in a different currency than expected.
To confirm and troubleshoot, check:
- Ad Account spending limits
- Recent changes to campaigns or bid strategy
