The Multi-Channel Ad Budget Pacing Playbook.

Why the budget spreadsheet breaks

Almost every team running multi-channel ad spend manages it from a spreadsheet one person built. It works until it doesn't: it's a single point of failure, it looks backward instead of forward, it has no memory of what changed, and month-end becomes a manual rebuild. Good pacing isn't a prettier spreadsheet — it's a discipline that works in any tool.

"I ran seven channels and about $1.7M a year off a sheet only I understood. It worked until the week I took off — then it stopped. The method below is what I wish I'd written down on day one." — Drew Washington, founder of Caeros

The pacing method, in six steps

1. 1

   Compare expected pace to actual spend

   Take the share of the month elapsed and apply it to the budget — that's where you'd expect to be today. Divide actual spend by that expected figure: over 100% means you're burning faster than a straight line to month-end.

2. 2

   Project where you'll land

   Extend today's run-rate to the full month: spent ÷ days-elapsed × days-in-month. This projected end-of-month number is the one that matters — react to the projection, not daily noise.

3. 3

   Set a real, cadence-aware daily floor

   Not every channel runs seven days. Pace each against the days it actually spends, and take planned dark days (holidays, freezes) out of the expected pace. Adjusted daily floor = remaining budget ÷ remaining active days.

4. 4

   Run weekly targets that self-correct

   Translate month-to-date pacing into weekly targets (W1–W5). Re-adjust each week based on what actually landed, so an early underspend automatically raises later targets to still finish on budget.

5. 5

   Catch overspend with a 10% trip-wire

   When a channel's projected end-of-month runs more than 10% over budget, flag it. Ease its daily floor early — a small mid-month correction beats a hard stop, or a line in the recap.

6. 6

   Reconcile and recover surplus

   At month-end, lock the month, compare budget to actuals, and decide deliberately what to do with underspend — roll it forward or reallocate it, instead of letting it vanish. Record every change as a new ledger line so the history is always explainable.
