A sponsor renewal rate definition that survives a board meeting

The sponsorship deck for the board says renewal is 67 per cent, up four points. Somebody from finance asks whether that includes the title sponsor who left. It does. They ask what share of last year's sponsorship revenue came back. Nobody has that number in the room, and the meeting moves on with everyone quietly discounting the 67.

A sponsor renewal rate definition is worth arguing about precisely because the arithmetic is trivial and the answer moves by twenty points depending on what you divide by. CEIR's B2B Exhibition Sponsorship Playbook, Part 1, published in October 2019 from more than 200 organiser executives and 728 exhibitors, put sponsorship at almost 20 per cent of B2B exhibition gross revenues. On a show turning over eight million, that is a line item large enough that a twenty point swing in how you describe its retention is a governance problem.

Three denominators, four answers

Take one edition. Eighteen sponsors last year, twelve of them back this year. Total sponsorship revenue last year was 640,000 dollars, and the six who left carried 290,000 of it.

Logo retention is 12 divided by 18, which is 66.7 per cent, call it 67.

Gross value retention takes the prior-edition spend of the sponsors who returned and divides by total prior-edition spend. The twelve returners carried 640,000 minus 290,000, which is 350,000. So 350,000 divided by 640,000 is 54.7 per cent, call it 55.

Net value retention counts what the returners are actually paying this year. If those twelve have grown to 395,000 between them, then 395,000 divided by 640,000 is 61.7 per cent. That figure can exceed 100 per cent in a good year, which is exactly why it is useful and exactly why it needs a label.

Asset line retention counts contract lines instead of companies. If the eighteen sponsors held 47 asset lines last edition and 34 of those same lines are sold again this year, that is 72.3 per cent.

Sixty-seven, fifty-five, sixty-two, seventy-two. One edition, four honest numbers, and the only dishonest act available is to quote whichever is highest without saying which one it is.

What counts as a sponsor at all?

Before any denominator works, decide who is in the population.

A company that bought a 3,000 dollar coffee break and a company that bought a 180,000 dollar title package are one unit each in a logo count. Most rate cards run from a few hundred dollars to six figures, so an organiser who sells forty small on-site items has a completely different-looking renewal rate from one who sells eight large packages, with identical revenue and identical commercial health.

Set a threshold. Any threshold is arguable, which is an argument for documenting it, holding it across editions and restating history when you change it. A defensible approach is to set the floor where the sales process changes, because below a certain value the asset is bought on a form and above it somebody has a conversation. That line is real in your own operation and you can find it by looking at which items ever get discounted.

Then decide the harder cases in advance and write them down.

Media partners taking barter. If no cash moved, do they count? Whichever way you answer, apply it to both the numerator and the denominator, and value the barter consistently, which is its own valuation question.

Exhibitors who also sponsor. An exhibitor buying a 900 dollar listing upgrade is usually not a sponsor for this purpose. An exhibitor buying a hall entrance branding package usually is. The threshold decides it, and that is a point in favour of having one.

Group entities. If a parent renews through a different subsidiary, the logo returned and the account identifier did not. Match on the ultimate parent and record that you did.

The window problem, and shows that are not annual

Renewal implies a previous edition and a next one, which is straightforward for an annual show and awkward for everything else.

CEIR's 2019 playbook asked exhibitors about sponsorship investment across a two-year window and found 83 per cent had invested in sponsorships within the prior two years, spending an average of nearly 14 per cent of their B2B exhibiting marketing budget on them. A two-year lookback is a reasonable way to think about buyer behaviour and a bad way to run a renewal rate, because it converts a skipped edition into a renewal and hides a real gap in the cash.

For an annual show, use consecutive editions and report a separate lapsed-and-returned count for sponsors who missed one. For a biennial show, consecutive editions are two years apart and the rate is genuinely comparable to an annual show's two-year figure, which is worth stating so nobody benchmarks you against the wrong thing.

The other window question is when you measure. A renewal rate calculated the Monday after the show closes and one calculated in March are different numbers, and both are legitimate. Pick a fixed measurement point, expressed as days before the next edition opens or days after the previous one closed, and use the same point every year. Sixty days after close is a common choice because the on-site renewals have landed and the slow ones have not yet been chased. What matters more than the choice is that the point does not drift, since a rate measured at day 60 one year and day 140 the next is a comparison of your sales calendar rather than your retention.

Which definition should you publish?

Publish two, with the rule attached to each.

The count figure and the gross value figure, side by side, in that order. The count tells you how many relationships survived and is the one your sales team can act on. The gross value figure tells you how much of last year's sponsorship money came back and is the one the board is actually asking about. Publishing only the first is how a show loses its title sponsor and reports an improvement.

Net value retention is worth adding once you have two clean years of it, because it is the only one of the four that captures growth inside the base. A show at 55 per cent gross value retention and 62 per cent net value retention is retaining less than it should and growing what it keeps, which is a different management problem from a show at 55 and 55.

Skip asset line retention as a headline. It is a useful operational diagnostic, and it moves for reasons that have nothing to do with sponsor sentiment, such as one package being restructured from six lines into three.

ANA and MASB, in their July 2018 report on sponsorship accountability metrics, found that 37 per cent of the 182 marketers they surveyed had a standardised process for measuring return on sponsorship at all. Read from the seller's side, that means the majority of your sponsors cannot tell you in a defensible way whether last year worked. Your renewal rate is therefore measuring their internal budget politics as much as their satisfaction, which is a reason to keep the definition simple enough that both sides can compute it.

Writing the definition down

One paragraph, kept with the report, restated every time the number is quoted.

Name the population and the threshold. Name the unit being counted. Name the two editions being compared and the measurement date. Name the treatment of barter, subsidiaries and multi-year contracts. State whether a sponsor who reduced spend by 80 per cent counts as retained, because someone will ask.

Multi-year deals deserve a specific sentence. A three-year contract signed two years ago is not a renewal decision this year, and including it in the numerator inflates the rate while the underlying sales work shrinks. Report contracted-forward sponsors separately, so the rate reflects decisions actually made in the period. When those contracts expire in the same year, the rate will drop for reasons everyone can see in advance, and the separate count is what lets you say so before it happens rather than afterwards.

The definition is also what makes the rest of the analysis possible. You cannot ask which signals predict renewal until you have a label to predict, and a label that changes meaning between editions produces a model that learns your reporting conventions. The same holds for splitting the rate by tenure and for reading how much of the returning revenue sits with a handful of accounts, both of which need this settled first.

Where this stops

A renewal rate is a lagging summary of decisions that were mostly made months earlier, and it compresses a portfolio of very different relationships into one fraction.

It also says nothing about replacement. A show that retains 55 per cent by value and sells 400,000 dollars of new sponsorship is in better shape than one retaining 80 per cent and selling 60,000, and the renewal rate ranks them the wrong way round. Report new business alongside it or the number will drive the wrong behaviour, which is sales effort pushed at the accounts easiest to keep.

The deeper limit is that the rate treats every non-renewal as a failure. Some are. Some are a sponsor whose category strategy changed, some are a contact who left, and some are you declining to sell to a company you would rather not have on the entrance banner. Retention analysis inside the wider exhibitor and sponsor picture only becomes useful when the non-renewals carry a reason code that a human entered at the time, because reconstructing the reason in February from an empty contract line is guesswork with a percentage attached.

This week, take last edition's sponsor list, add a column for prior-edition spend, and compute the count figure and the gross value figure. If they differ by more than ten points, the smaller one is the story, and it is better told by you than found by someone else in a board meeting.
