Ad Spend Pacing Calculator
Use campaign budget, spend-to-date and elapsed campaign percentage to compare current spend with a straight-line pacing plan.
How to use this calculator
- Enter total campaign budget, spend to date, campaign elapsed (%) using the same measurement window and units.
- Check the result and intermediate values, then change one input at a time when comparing scenarios.
- Keep the stated scope and assumptions attached to any result you share.
Formula and method
Planned spend = total budget × elapsed percentage; pacing variance = actual spend − planned spend.
- Planned €2,000; actual spend is €150 below a straight-line pacing plan.
- This assumes an even spending schedule. Auctions, launch ramps, weekends and campaign strategy can make linear pacing inappropriate.
Worked examples
Worked example
A €5,000 budget is 40% through its run and €1,850 has been spent.
Planned €2,000; actual spend is €150 below a straight-line pacing plan.
Planned €2,000; actual spend is €150 below a straight-line pacing plan.
Understanding the result
Planned €2,000; actual spend is €150 below a straight-line pacing plan.
This assumes an even spending schedule. Auctions, launch ramps, weekends and campaign strategy can make linear pacing inappropriate.
Important notes
This assumes an even spending schedule. Auctions, launch ramps, weekends and campaign strategy can make linear pacing inappropriate.
Use measured inputs or documented assumptions, and validate important decisions with the appropriate source specifications or professional guidance.
Frequently asked questions
Does being under pace mean performance is good?
No. Compare spend with conversions, quality and delivery goals; underspend can mean insufficient reach.
Can campaigns intentionally use uneven pacing?
Yes. Replace the linear benchmark with your planned schedule when spend is seasonal or front-loaded.
