A recoup rate asks a simple question: when ad money leaves one channel, how much actually comes back to the same sellers somewhere else? In TV, it tracks how much spend leaving linear broadcast lands on broadcasters’ own streaming inventory rather than Google, Meta or Amazon.
That distinction matters because broadcasters have long argued that audience migration to on-demand is internal. But spend records tell a different story.
What recoup rate actually measures
No ad server reports it. The ratio comes from spend-tracking firms working off agency billing data. Guideline, which tracks roughly $200 billion in annual media investment across 65 countries, is the source of the published television figures.
The method is source-of-volume analysis: reconstructing a channel’s growth from the channels that funded it. A worked example of US out-of-home shows digital performance taking $104.84 million out of the pool while TV added $248.25 million, making a net gain possible. A recoup rate filters that same ledger to a single seller group and single origin channel.
In practice, the numerator is money arriving on broadcaster video on demand. The denominator is money confirmed as having left linear. Neither side yet has the standardised accreditation buyers expect elsewhere.
Why the UK number is a warning
Guideline data relayed on the Media Unfiltered podcast shows roughly 15p of every pound leaving the UK linear market is recouped on broadcaster streaming. The US recovers about twenty-five cents in the dollar, and Canada around twenty cents. Of the three, the UK recovers the least.
The price structure explains the gap. UK linear inventory clears at $4 to $5 CPM on Guideline’s dollar data, while UK broadcaster VOD sits near $22 to $25. That is a fivefold jump. YouTube pricing sits close to the linear band at around $5.
The result is what analyst Ian Whittaker calls cheap-tier retention. Linear is now the affordable tier where broadcasters compete with platforms on price. A switch-off removes that tier. The premium attached to broadcaster streaming makes it harder to sell at volume.
What media buyers should watch
The recoup rate becomes decisive when silos break. Nielsen’s 2026 Upfront Planning Guide quantified the mismatch: streaming took 66.7% of ad-supported TV time among adults 18 to 49, while linear still captured 67.5% of television ad spend. Once those budget lines merge, the recoup rate decides how much broadcasters keep.
Holding companies have their own incentive to merge lines. Principal media deals can carry higher margin than transparent agency buys, and linear sits closest to the agency model while CTV and programmatic sit closest to principal. Concentration amplifies this: Omnicom completed its Interpublic acquisition in late 2025, and WPP pools client spend to negotiate as a single buyer.
The stakes are specific in the UK. Liberty Sky estimates commercial public service media advertising of about £3.9 billion in 2026. If terrestrial continues, that drifts to £3.64 billion by 2034. If it ends, the figure falls below £3.1 billion—a roughly 16% decline and cumulative losses near £3.5 billion between 2028 and 2036.
What to do with it
Don’t mistake recoup rate for a fill rate, payback period or incrementality test. It is not about unsold inventory, time to recoup campaign spend, or causal lift. It asks only where the invoice went.
Smart performance teams can apply the same logic to their own budget:
- Map spend by destination, not just channel: linear, BVOD, YouTube, programmatic CTV.
- Benchmark effective CPMs across those lines so migration is a decision, not an assumption.
- Model what happens if silos merge or a channel is removed from the plan.
- Watch whether higher-priced broadcaster streaming really converts at the same volume as cheaper YouTube inventory.
There are limits. Source-of-volume models allocate flows by pattern, agency panels miss self-serve budgets, and price direction is contested. But the core lesson holds: audience migration does not guarantee budget migration. Recoup rate is the arithmetic test of that claim, and right now most of the money is not coming back.
