Pace vs. budget

Enter values to calculate
Pace = actual spend to date ÷ expected spend at this point in the month (monthly budget × days elapsed ÷ days in month). 100% means you're exactly on pace; above 110% means you're overpacing and likely to exceed budget, below 90% means you're underpacing.

FAQ
Budget pacing calculator FAQ
What is budget pacing?
Budget pacing measures whether a campaign's spend is tracking evenly toward its monthly budget over the course of the month, rather than running out early or leaving budget unspent.
How is pacing calculated?
Pace = actual spend to date ÷ expected spend to date, where expected spend to date is the monthly budget multiplied by the fraction of the month that has elapsed (days elapsed ÷ days in month). 100% means spend is exactly on schedule.
What does overpacing mean?
Overpacing means a campaign is spending faster than its budget allows for the point reached in the month — it's projected to exhaust the monthly budget before the month ends unless spend slows down.
What does underpacing mean?
Underpacing means a campaign is spending slower than needed to use the full monthly budget by month-end — it's projected to leave budget unspent unless spend increases.
How is projected month-end spend calculated?
Projected month-end spend = (spend to date ÷ days elapsed) × days in month. It extrapolates the current daily spend rate across the rest of the month to estimate the final total.
