How this tool works

This calculator compares actual spend to the linear budget pace expected by the report date, then estimates remaining budget, daily pace needed, projected final spend, CPA, and ROAS where inputs are available.

Formula or template logic

totalDays = daysBetween(startDate, endDate) + 1; elapsedDays = clamped daysBetween(startDate, reportDate) + 1; plannedSpendToDate = totalBudget * elapsedDays / totalDays; pacingGap = spendToDate - plannedSpendToDate; remainingBudget = totalBudget - spendToDate; dailyBudgetRemaining = remainingBudget / remainingDays; projectedSpend = spendToDate / elapsedDays * totalDays; CPA = spendToDate / conversionsToDate when conversions are available; ROAS = revenueToDate / spendToDate when revenue and spend are available

Example use case

Use this while a campaign is live to see whether spend is ahead or behind the planned pace and how much budget should be spent per remaining day.

Frequently asked questions

What is budget pacing?

Budget pacing compares actual spend with the amount that should have been spent by a certain date to stay on plan.

Does this connect to ad platforms?

No. Enter the budget, spend, dates, conversions, and revenue from your own reports.

Why use linear pacing?

Linear pacing is a simple baseline. You can still adjust for launch ramp, weekends, sales cycles, or planned bursts.

What if spend is over pace?

Reduce daily spend, improve efficiency, or confirm that the campaign is intentionally front-loaded.

What if spend is under pace?

Increase daily spend carefully, check delivery limits, or extend the campaign if the remaining pace is unrealistic.
