Programmatic Dollar Tracer
Enter your monthly budget and your supply-chain take-rates, and watch the dollar travel: how much survives the ad-tech tax, the made-for-advertising waste, and the non-viewable inventory — and how much of the leak you can get back without spending more.
Only about a third of a programmatic dollar reaches a real, viewable person — the rest is taken by fees, lost to MFA and fraud, or served where no human saw it. This tracer runs your budget through three stages in sequence (fees, then MFA, then non-viewable) to compute your working media, your true effective CPM (you pay for the whole budget but only the working part performs), the single biggest leak, and what a best-practice chain would recover. Nearly all of the leak is recoverable.

How to use this calculator
- Enter your monthly budgetUse your real monthly programmatic media spend before any fees or waste. This is the dollar the tool will trace from the top of the supply chain to the viewable impression at the bottom.
- Set the ad-tech taxEnter the total fees taken by the DSP, exchanges, SSPs, and data vendors. The ANA and ISBA/PwC studies put this near a quarter to a third of spend; the default is calibrated to those findings.
- Set MFA & fraud wasteEnter the share lost to made-for-advertising sites and invalid traffic. This is the slice that buys impressions on junk inventory built only to harvest ad dollars.
- Set non-viewable / unmeasuredEnter the share of impressions a human never actually saw — served below the fold, unmeasured, or out of view. The tool applies it to what survives the first two stages.
- Read working media and the biggest leakThe big number is your working media; the subs show the share reaching a person and your true effective CPM. The footline names the biggest leak to fix first and the money a clean chain recovers.
RGM Expert Says
We built this because the headline CPM on a programmatic invoice is a fiction until you subtract the tax and the waste. Two big audits — the ANA in the US and ISBA/PwC in the UK — traced real spend and landed in the same uncomfortable place: only about a third of a programmatic dollar reaches a real, viewable person. The point is not to abandon programmatic. It is to stop running it on autopilot, because nearly all of the leak is recoverable.
The discipline the tracer enforces is fixing the largest hole first. Marketers tend to chase the loudest vendor or the newest tactic; the model insists on the biggest leak instead. Raise the fees and it points at supply-path optimization; raise the MFA share and it points at blocklists and fraud filters. That ordering is the whole game — the next dollar of savings lives where the leak is widest, not where the conversation is loudest.
Because the model is transparent, the plan it produces is one you can defend to a board, not a number you take on faith. The dollar passes through three stages in sequence and the math is in the open: working media is budget times one-minus-fees, times one-minus-MFA, times one-minus-non-viewable. When a client wants the version that runs on their real log-level data — and the program to act on it — that is what an engagement with RGM is for.
How it works
No black box. The dollar passes through three stages in sequence: the ad-tech tax takes its fees, then a share of what is left is lost to MFA and fraud, then a share of the remainder is non-viewable or unmeasured.
- Ad-tech tax — fees stacked across the DSP, exchanges, SSPs, and data vendors.
- MFA & fraud — spend on made-for-advertising sites and invalid traffic.
- Non-viewable — impressions served where no human saw them.
- Recoverable — the gap between your working media and a best-practice chain (fees 15%, MFA 5%, non-viewable 12%).
Worked example: a $100,000 budget at a 29% tax, 25% MFA waste, and 30% non-viewable leaves about $37,000 of working media — roughly 37% reaching a person, a 2.7× true effective CPM. The biggest leak is the ad-tech tax at $29,000, so supply-path optimization is the first fix; a clean chain recovers about $34,000 a month. Defaults are calibrated to the ANA and ISBA/PwC findings; every figure is a transparent planning assumption (RGM analysis).
Why most of the dollar leaks
Two big audits — the ANA in the US and ISBA/PwC in the UK — traced real programmatic spend and reached the same conclusion: only about a third of a programmatic dollar reaches a real, viewable person. Roughly a quarter to a third is taken by ad-tech fees across a long supply chain, and another large slice evaporates in made-for-advertising sites, fraud, and non-viewable impressions. You buy a dollar of media and a third of it shows up.
Most media calculators report impressions and CPMs at face value — the exact numbers that hide the leak. This one assumes what the audits proved: that the headline CPM is a fiction until you subtract the tax and the waste. It surfaces the true effective CPM, names the biggest leak so you know what to fix first, and quantifies the recoverable money so transparency becomes a budget line, not a virtue.
The fixes are concrete and ordered by size. The ad-tech tax falls to supply-path optimization — buying through fewer, shorter, authorized paths so you stop paying duplicate tolls. MFA and fraud fall to blocklists and pre-bid filters. Non-viewable inventory falls to viewability floors and attentive placements. Trace the dollar, fix the largest hole first, then re-trace and fix the next one.
What the audits found
Defaults in this tool are calibrated to the major programmatic-supply-chain studies. Your real numbers depend on your supply paths and inventory; treat these as directional planning anchors, not guarantees.
| Leak | Typical share | Fix |
|---|---|---|
| Ad-tech tax (fees) | ~25–33% of spend | Supply-path optimization |
| MFA & fraud | large variable slice | Blocklists, pre-bid fraud filters |
| Non-viewable / unmeasured | large variable slice | Viewability floors, attentive media |
| Reaches a person | ~one-third of the dollar | Clean the chain, re-trace |
What the supply-chain studies say
Roughly a third of a programmatic dollar reaches the consumer; the rest is consumed by an opaque supply chain of fees and unidentifiable spend.
Only about half of advertiser spend reached the publisher, with an unattributable share that no party could explain.
