The marketer's guide to budget pacing

Budget pacing is the practice of tracking actual spend against planned spend throughout a period — daily, weekly, or monthly — so you can adjust before it is too late. It sounds simple. In practice, most marketing teams only discover pacing problems at month-end reconciliation.

Why pacing matters

Over-pacing means you blow through budget early, leaving days or weeks with no active media. Under-pacing means unspent budget that could have driven pipeline. Both cost you revenue.

The gap between "on track" and "off track" compounds quickly. A 5% daily overspend becomes 15% by week three. By the time a manual spreadsheet catches it, the damage is done.

The pacing formula

At its core, budget pacing compares two numbers:

• Expected spend to date = (monthly budget / days in month) * days elapsed
• Actual spend to date = sum of all channel spend reported so far

The variance (actual minus expected, as a percentage) tells you whether to accelerate, hold, or pull back.

Common pacing mistakes

• Checking pacing weekly instead of daily when spend is volatile.
• Ignoring channel-level breakdowns — total spend can look fine while one channel is 40% over.
• Using platform-reported spend without accounting for reporting lag (most platforms lag 24-72 hours).
• Not setting up alerts for threshold breaches (over 10% variance should trigger a review).
