Budget pacing glossary
31 terms paid media, marketing operations and finance teams use when they keep ad spend on plan, with the Google Ads, Microsoft Advertising and LinkedIn Ads rules behind them.
In short
Budget pacing compares what a campaign has spent with what it should have spent by now. Pace is spend to date divided by expected spend to date; expected spend is the budget times the time elapsed over the time in the period; the daily budget to hit is the budget left over the time left.
Every other term on this page refines one of those three numbers.
A
- Accelerated pacing
- A delivery option that spends a budget as quickly as possible. LinkedIn’s Marketing API describes ACCELERATED pacing for events; Microsoft Advertising lists an accelerated daily budget type. LinkedIn Ads budget pacing
- Accrual (ad spend accrual)
- Ad spend recorded in the month it was incurred, before the platform invoice arrives, so the books close on time. Pacing data per campaign is the usual source of the accrual figure. Ad spend accruals at month end
- Ad schedule (day-of-week)
- A setting that turns a campaign off on some days or hours. Since June 1, 2026, Google paces campaigns whose schedule turns whole days off to up to 30.4 times the average daily budget per month. Google’s June 2026 ad schedule pacing change
- Average daily budget
- Google Ads’ budget unit: what a campaign should spend on an average day. A campaign can spend up to 2 times it on a day and up to 30.4 times it in a month. Google Ads budget pacing
B
- Budget left
- Monthly budget minus spend to date. Negative budget left means the period is already overspent.
- Budget pacing
- Comparing what a campaign has spent with what it should have spent by now, then adjusting the daily budget so the period lands on plan. What is ad budget pacing?
- Budget phasing
- Splitting an annual or quarterly budget into monthly targets: evenly, by business days, by last year’s shape or loaded toward launches. January budget reset
- Burn-up chart
- A chart of cumulative spend against the cumulative plan through the month. The gap between the lines is the drift to fix.
C
- Campaign total budget
- A Google Ads budget type that sets one amount for a campaign’s whole run (3 to 90 days for most types). Google adjusts daily spending to use it; it is only available for new campaigns. PPC budget automation
- Cut-to-date pacing
- Pacing that counts today’s hours up to the moment spend was pulled, so a morning check is not compared with a full day of budget. Cut-to-date pacing for enterprise
D
- Daily budget to hit
- Budget left divided by the active days left: the daily spend that lands the period exactly. Each platform needs it translated into its own setting. PPC budget pacing calculator
E
- Expected spend to date
- Monthly budget x time elapsed / time in the period: what a campaign should have spent by now. Budget pacing formulas for Excel and Sheets
F
- Flight (flight dates)
- The start and end dates of a campaign that does not run the whole month, such as a webinar push or an event. Pace a flight against its own dates, not the calendar month.
G
- Guardrail
- A limit on automated or manual budget changes: a floor, a cap, a maximum change per run, or an approval threshold above which a person must approve. PPC budget automation
L
- Lifetime budget
- A total amount for a campaign’s whole run, used by LinkedIn Ads among others. LinkedIn recommends lifetime budgets with lifetime pacing. LinkedIn Ads budget pacing
- Lifetime pacing
- LinkedIn’s pacing that predicts platform activity over one week and distributes spend across the campaign’s life to match.
- Limited by budget
- A campaign that would get more traffic with a larger budget. Only these campaigns can use a budget increase; others are limited by bids, audience or demand.
M
- Month-end forecast
- Where spend lands at the end of the period if nothing changes: spend to date / time elapsed x time in the period, ideally with a range. How to forecast month-end ad spend
- Monthly spending limit
- The most a campaign can be charged in a month. In Google Ads it is 30.4 times the average daily budget for most campaigns; in Microsoft Advertising, the daily budget times the days in the month. Google Ads and Microsoft Ads in one view
O
- Overdelivery
- A platform spending more than the daily budget on a given day. Google allows up to 2 times the average daily budget; Microsoft says it usually keeps overspend under 100% above the daily limit. Why Google Ads goes over the daily budget
- Overpacing
- Spending faster than plan: pace above the tolerance band, for example above 110%.
P
- Pace
- Spend to date divided by expected spend to date. 100% is on plan, 115% is 15% ahead, 85% is 15% behind. PPC budget pacing calculator
- Pacing alert
- A notice that a campaign is off pace. The useful ones combine a percent band with a dollar floor, plus alerts for daily spikes, spend with no budget and stale data. Budget pacing alert thresholds
- Pacing report
- A table of every campaign’s budget, spend to date, pace, forecast and the daily budget to set, sorted by the money at stake. What a budget pacing report should show
R
- Reallocation
- Moving budget from campaigns that cannot spend it well to campaigns that can. A pipeline decision as much as a pacing one. The cost of ad budget underspend
- Run rate
- Average spend per elapsed day (or hour). Multiplied by the days in the period, it gives the straight-line month-end forecast.
S
- Stale data
- Spend figures that have not updated since the last expected refresh. Pace judged on stale data is wrong, so it deserves its own alert.
T
- Tolerance band
- The range around 100% pace treated as on plan, for example 90% to 110%. Wider for new, small or weekday-only campaigns.
U
- Underpacing
- Spending slower than plan: pace below the tolerance band, for example below 90%.
- Underspend
- Budget approved for the period that is not spent by its end. Approved pipeline that was never created, and often a smaller budget next quarter. The cost of ad budget underspend

Questions
Budget pacing terms, answered
What does pacing mean in advertising?
Pacing is comparing what a campaign has spent with what it should have spent by now, and adjusting the daily budget so the month, quarter or flight lands on plan.
What is the difference between pace and run rate?
Pace compares spend to date with expected spend to date (100% is on plan). Run rate is average spend per elapsed day; multiplied by the days in the period it gives the month-end forecast.
What is cut-to-date pacing?
Pacing that counts today’s hours up to the moment spend was pulled, so a morning check is not compared with a full day of budget. It removes false underpacing in the morning and false overpacing at night.
What is overdelivery in Google Ads?
Spending more than the average daily budget on a given day. Google allows up to 2 times the average daily budget on a day, within a monthly limit of 30.4 times it for most campaigns.
