Primary Percentage Sold
Also known as: Percent sold, Primary sell-through, % sold
Primary percentage sold is the share of an event's capacity already sold on the primary market, calculated as capacity minus primary tickets still available, divided by capacity.
It puts events of different sizes on the same scale: 2,000 tickets left means little in a stadium and a lot in a club. Events above 90% sold early in the sale are the classic sell-out candidates.
It's the primary-market version of the sell-through rate and is built on venue capacity and primary availability.
How primary percentage sold is calculated
Primary percentage sold = (capacity − primary tickets available) ÷ capacity × 100. Both inputs need to describe the same thing: the capacity of this show's configuration, and the primary tickets — not resale — still on sale on the official site.
Because capacity minus availability includes every seat that isn't on sale, the result really measures the share of the venue no longer available from the organiser. Most of that is sold tickets; some of it is holds and production kills that haven't been released yet.
Worked example: an arena and a club on one scale
A 15,000-capacity arena has 1,350 primary tickets left. Primary percentage sold = (15,000 − 1,350) ÷ 15,000 = 13,650 ÷ 15,000 = 91%.
A 1,500-capacity club with 600 primary tickets left is (1,500 − 600) ÷ 1,500 = 60% sold. In raw numbers the arena has more than twice as many tickets left; in proportion it is much closer to selling out. That is the point of the percentage: it puts both events on one scale.
Using primary percentage sold to find sell-out candidates
Screening by primary percentage sold is a quick way to narrow a long list of events. A practical approach:
- Filter for events above a threshold — say 85% sold — with the date still weeks away.
- Check sales velocity: a high percentage plus steady daily sales means the rest will go.
- Look at section availability: the remaining stock may all sit in one poor section.
- Compare with resale prices: a high percentage sold with a get-in price still near face value suggests the market hasn't priced in the sell-out yet.
Primary percentage sold vs sell-through rate
Both measure how far through its supply an event is. The sell-through rate divides by the tickets released so far (sold plus available); primary percentage sold divides by capacity. Before holds are released, primary percentage sold reads higher, because unreleased seats count as gone. Late in the sale, when nearly everything has been released, the two numbers converge.
Pitfalls when using primary percentage sold
The formula is simple; the inputs are where it goes wrong:
- Wrong capacity: using the venue's headline maximum instead of this layout makes events look less sold than they are.
- Early in the sale: holds and unreleased tiers inflate the percentage before most tickets have actually sold.
- Releases lower it: a restock of held seats can drop the figure by several points overnight.
- Resale mixed in: if resale stock is counted as available, the percentage reads too low.

Frequently asked questions
How do you calculate the percentage of tickets sold?
Subtract the primary tickets still available from the event's capacity, divide by capacity and multiply by 100. With a capacity of 8,000 and 1,200 tickets left, (8,000 − 1,200) ÷ 8,000 = 85% sold.
What percentage sold means an event will sell out?
There is no fixed line, but events above about 90% with weeks to go and steady sales usually sell out. Timing matters more than the number: 90% the day after the on-sale is far stronger than 90% the night before the show.
Why can primary percentage sold go down?
Because primary availability went up. Released holds, cancelled orders, an added standing area or a new price tier all add primary stock and lower the percentage, without anyone returning a ticket. A sudden drop is usually a restock worth checking.
Can I filter events by percentage sold?
Eventory's MarketTIQ lets you filter events by primary percentage sold and by primary and secondary availability, and the Ticketmaster venue map shows the sold percentage, capacity and availability for every section of the venue.
