Marketing Budget Pacing Calculator
Check whether a campaign is on pace to spend its budget on schedule, and find the daily spend required to finish on target.
Formula & Date Convention
Start and end dates are inclusive. A campaign running from January 1 to January 10 is 10 days long, not 9 — both the start day and end day count as full spending days. The as-of date is treated the same way: it's counted as a day that has already fully elapsed.
- Total Campaign Days = (End Date − Start Date), inclusive
- Days Elapsed = (As-Of Date − Start Date), inclusive, clamped between 0 and the total days
- Expected Spend to Date = Total Budget × (Days Elapsed ÷ Total Days)
- Pacing Difference = Actual Spend − Expected Spend to Date
- Remaining Budget = Total Budget − Actual Spend
- Required Daily Spend = Remaining Budget ÷ Days Remaining
If the as-of date is before the start date, the campaign hasn't started and expected spend is $0. If it's after the end date, the campaign is complete, there are no remaining days, and required daily spend isn't applicable.
Worked Example
A campaign runs from January 1 to January 10 (10 days) with a $1,000 budget. Checking pacing on January 5 (5 days elapsed), expected spend to date is $1,000 × (5 ÷ 10) = $500. If actual spend is $600, that's $100 ahead of pace, with $400 remaining budget over the 5 remaining days — a required daily spend of $80 per day to finish exactly on budget.
