google just changed how scheduled campaigns pace budget.
most people missed it.
previously, google paced your daily budget against active scheduled days.
a $100/day campaign running mon–fri spent roughly $2,200/month.
after march 1 (june 1 for the next wave): google now paces toward 30.4 × your daily budget - regardless of how many days your schedule runs.
that same mon–fri campaign now targets $3,040/month.
same budget. same schedule. 38%.
the math:
- weekends only, $100/day → up to $1,600/month ( 100%)
- mon–fri, $100/day → up to $3,040/month ( 38%)
- seasonal/flighted campaigns → some accounts seeing 50–100% overspend
one concrete case: a $3,550/day mon–fri campaign expected $74,550 in may.
under the new pacing, google targets $107,920.
that's $33,370 unplanned.
why it compounds:
- maximize conversions and maximize conversion value now have more headroom to spend toward
- mid-month overspend creates a dead zone in the final 7–10 days where impression share collapses
the fix: new daily budget = intended monthly spend ÷ 30.4
$2,200/month ÷ 30.4 = $72.37/day
$800/month ÷ 30.4 = $26.32/day
what to do now:
- audit every campaign with a custom ad schedule
- recalculate daily budgets using the formula above
- switch maximize conversions/value to tCPA or tROAS
- monitor budget pacing panel weekly through june
the passive protection of limited schedules is gone.
what used to manage itself now requires active recalibration.
