Pacing result
Day 12 of 30: ideal spend is 1,600 but actual is 1,350 — 84% of pace. Remaining 2,650 over 18 days means 147 a day to finish on budget.
How the Ad Budget Pacing Calculator works
- Enter the total budget for the period and how far through it you are.
- Add the spend to date from the ad platform, not your invoice.
- Adjust the daily cap toward the required figure gradually — a sudden jump disrupts delivery.
The method
Pacing compares what you have spent with what an even burn would have spent by now, then divides the remainder over the days that are left.
pace % = spend to date / (budget x days elapsed / total days); required daily = (budget - spend) / days remaining
At 1,350 spent of a 4,000 budget on day 12 of 30, ideal is 1,600, so pace is 84% and the remaining 18 days need 147 a day.
FAQ
Is underpacing always bad?
No. It can mean cheap conversions and a limited audience, or it can mean your bids are too low to enter auctions. Check impression share before raising budgets to fix a pacing number.
Why does spend spike at the end of a month?
Because someone corrects an underpaced campaign in the final days. Spending the remainder in a week buys the worst inventory of the month; smooth adjustments are cheaper.
Should daily caps be adjusted every day?
No. Platforms need days to stabilise delivery after a change. Adjust weekly unless pacing is badly off.
