Working-Media Calculator
In programmatic you do not buy ads; you buy a supply chain. Enter your spend and pick your channel, and this tool shows how much of every dollar actually reaches a real, viewable person — and how much disappears into fees and waste before it ever gets there.
Working media is the share of a programmatic budget that reaches a real, viewable person, after the ad-tech take rate (DSP, exchange, SSP, and data fees) and impressions that are non-viewable, fraudulent, or unmeasured. Industry audits put it near a third of the dollar. This tool combines your spend, a channel-based fee benchmark you can edit, and your verified viewable-and-valid rate to show working media in dollars and percent, your true effective CPM, and the spend you could recover by cleaning the supply path.
Working-Media Calculator inputs and result
How to use this calculator
- Enter your monthly spendUse total programmatic budget for the month so the recovery figure is monthly too.
- Pick your primary channelThe dropdown loads benchmark fee and viewability rates for that channel. CTV and PMP run cleaner; open-exchange display runs the dirtiest.
- Replace the benchmarks with your dataPut in your real ad-tech take rate and your verified viewable-and-valid rate from DV or IAS. Your numbers beat any benchmark.
- Read working media and true CPMThe headline is the share of budget reaching a real person; the sub-metrics show the dollars, your true effective CPM, and what cleanup could recover.
- Act on the supply path, then exportIf working media is low, consolidate supply paths, block MFA, and set a viewability floor. Copy a share link or export the CSV for the media review.
RGM Expert Says
The first number we pull on any programmatic account is working media, because it reframes every other metric. A campaign with a respectable CPM and CTR can still be sending two-thirds of its budget to fees and unviewable junk, and no amount of bid tuning fixes that. Working media tells us whether the problem is the media plan or the supply chain underneath it.
Most of the recoverable money hides in the supply path. The same impression is often sold through a dozen routes, each adding a fee, and the open exchange is where made-for-advertising sites and invalid traffic concentrate. Consolidating to authorized, direct paths and curated inventory routinely lifts working media by double digits without touching reach — it just stops paying for waste.
We hold programmatic to outcomes, never impressions. Once working media is healthy, we judge the channel on incremental lift through geo and holdout tests, not the platform's self-reported conversions. Trace the dollar, prune the path, block the junk, and measure what is real — in that order — and the same budget quietly starts reaching far more of the people it was meant to.
How it works
The calculation is two sequential haircuts on the budget. The ad-tech take rate is removed first, then the remaining media is reduced by the share of impressions that are not viewable or not valid. What survives both is working media. Because you still paid the full budget, the true effective CPM is one divided by the working-media share.
- Ad-tech take rate — the combined fees of the DSP, exchanges, SSPs, and data before the publisher is paid.
- Viewable & valid rate — the share of impressions that are viewable, non-fraudulent, and measured.
- Working media — budget that reaches a real, viewable person.
- True effective CPM — what you really pay per thousand reaching people, versus the invoice rate.
Best-practice recovery assumes a cleaned chain of ~15% fees and ~78% viewable-and-valid; figures vary by inventory. See RGM’s programmatic field guide.
Why working media is the only programmatic number that matters first
Industry audits keep landing in the same place: only about a third of a programmatic dollar reaches a real, viewable person. The ANA found roughly 36 cents on the dollar after fees and waste, and the ISBA studies found a stubborn slice of spend that could not even be traced. Average CPMs and click metrics look fine while most of the budget never reaches a human, which is why working media has to be the first thing you measure.
The waste is unusually fixable because it is a hygiene problem, not a strategy problem. Made-for-advertising sites, invalid traffic, and non-viewable placements are removed with blocklists, fraud filters, and viewability floors; duplicate fees are removed with supply-path optimization. Both routinely return double-digit percentages of a budget that was buying nothing, which is why disciplined buyers treat the supply chain itself as the thing they manage.
Used well, working media turns a vague sense that programmatic is wasteful into a number you can act on and a target you can hold a partner to. It exposes the true cost of a cheap CPM, quantifies the prize of cleaning the chain, and keeps the focus on the only thing that ever mattered: budget that actually reaches the people you are trying to influence.
Working-media and viewability by channel
Typical fee load and viewability vary widely by channel. Treat these as orientation; your verification data is the real input.
| Channel | Typical viewable & valid | Note |
|---|---|---|
| Open-exchange display | ~45% to 55% | Cheapest, dirtiest; MFA and IVT concentrate here |
| Online video | ~60% to 70% | Higher engagement, watch for auto-play and fraud |
| Connected TV (CTV) | ~85% to 95% | Premium and viewable, but verify real CTV inventory |
| PMP / curated | ~70% to 85% | Vetted inventory at negotiated terms |
What the experts say
We have a media supply chain that is murky at best and fraudulent at worst. We need to clean it up.
