Media waste rarely appears as one obvious line in an advertising report. It accumulates through excess frequency, overlapping audiences, and invalid or low-quality traffic.
This calculator provides a directional estimate of avoidable spend. It is designed for budget triage and scenario planning, not as a substitute for an incrementality study or a platform audit.
Estimate avoidable media spend
Directional estimate only. Validate with platform, reach, placement, conversion-quality and incrementality data before changing budget.
How the estimate works
The model treats excess frequency, audience overlap, and low-quality traffic as partially overlapping sources of waste. It applies them sequentially rather than simply adding the percentages, which avoids counting the same impressions more than once.
How to use the result
Start with the largest estimated source of waste, validate it against reach and placement data, and run a controlled budget reallocation. The useful output is not the headline number but the next test it helps you prioritize.
