Concert Sell-Through Rate: The Denominator Matters

Sell-through is the number a promoter checks first in the morning and the number a publicist quotes when the show is over. Between those two uses it changes meaning, and the change is almost always in the denominator. This page fixes the definition, shows the arithmetic on an illustrative manifest, and is explicit about the thing most sell-through discussions imply and never demonstrate: that some level is normal.

Definition

Sell-through is paid tickets over sellable inventory. Paid means tickets for which the box office received money; comps are excluded, because a comp is distributed but not paid. Sellable means the inventory the public could actually buy: capacity less kills, operational and accessible inventory, and holds, as the inventory page sets out. The figure is time-stamped. Sell-through at 21 days out and sell-through at the door are different observations of the same show, and a figure quoted without a date is half a figure.

The denominator problem

The calculator on this page starts from 4,000 paid tickets, 4,400 sellable seats and 5,000 capacity at 21 days out; every input is illustrative. On sellable inventory the show is 90.9 percent sold. On capacity it is 80.0 percent sold. Nothing about the show changed between the two sentences. The 600 seats that separate them were killed by the production, reserved for operations and accessible seating, or held by the parties, and none of them was ever offered to the public. A sell-through computed on capacity therefore measures the show against tickets that did not exist, and a claim of the form "the venue was only X percent full" made from a capacity figure is a claim about the building, not about demand.

The reverse error is also common. Because holds release back to sale, sellable inventory grows as the show approaches, and a sell-through that looked strong against an early manifest can fall against a late one without a single ticket being refunded. That is a bookkeeping effect, not a demand signal, and a pacing analysis that does not hold the denominator constant will misread it. The pacing page deals with that comparison.

The measurement moment

Sell-through is a snapshot, and the snapshot has a date. The same show has a sell-through at the close of the artist presale, one at the end of the first on-sale week, one on the day of show and a final figure at settlement, and these are different numbers that answer different questions. A mid-campaign figure feeds the velocity projection and the pacing comparison; the final figure is what the settlement is computed on. Comparing one show’s final sell-through with another’s three weeks out is not a comparison. The denominator can also move between snapshots, as production holds are released or kills are confirmed, and refunds and exchanges after a measurement can lower a figure that was already reported. Any sell-through stated on Live Index therefore carries its measurement moment, and any figure encountered elsewhere without one should be treated as undated.

There is no benchmark

Search traffic to this topic is dominated by one question: what is a good sell-through rate? The public record contains no answer. No statistical programme collects per-show sales against sellable inventory, promoters do not publish it, and trade reporting of grosses does not carry a denominator. The figures that circulate are either anecdote or derived from capacity, and the previous section explains why the latter measures the wrong thing. Live Index therefore states no typical, healthy or break-even sell-through. What a show needs to sell is a function of its own guarantee, expenses and scale, and the break-even page shows how to compute that number for a specific deal rather than borrow one.

Sold out is a sell-through claim, not a financial one

A sell-out is 100 percent sell-through against whatever inventory the seller has defined, and the definition is the seller's. A show can be announced as sold out while holds remain unreleased, while accessible seats are legitimately retained under federal guidance, or while a later production release is planned. None of that is improper; it is why the phrase is a statement about inventory status, not about how many people will be in the room. Nor does it say anything about money. Live Index's festival research on why a sold-out event can still be a bad business makes the longer version of that argument, and the settlement guide shows the arithmetic: a full house at a scale that does not cover the guarantee and the nut is a full house that lost money.

Reading a sell-through claim

• Which denominator: sellable inventory or capacity? If the answer is not stated, assume capacity and treat the figure as a lower bound on the number that matters.
• Which numerator: paid tickets, or tickets distributed including comps?
• Which date: at announcement, at some days-out marker, or at the door?
• Which manifest: were holds released or production seats added between the figure's date and the show?

A figure that answers all four is an observation. A figure that answers none is a mood.
