Why the headline attendance number is the wrong starting point
A festival programmer rings us in February and asks for a quote on 50,000 cups for a 50,000-capacity weekend. It feels intuitive: one cup per ticket. It is also wrong in both directions. Without a wash loop you will run dry by Saturday lunchtime. With a deposit-return scheme working properly, you can serve the whole crowd on a tenth of that volume. The right number depends on three things: drinks served per head, how many cups rotate back through wash, and your tolerance for running out.
The base formula
Across the events we supply, drinks per attendee per day shakes out at four to seven, with the lower end for family-orientated festivals and the upper end for music weekenders with multiple bar zones. Multiply attendance by drinks per head by event days. That is your gross drink volume.
If every drink uses a fresh cup with no wash loop, that gross figure is also your cup order. For a 20,000-cap, three-day festival serving five drinks per head per day, that is 300,000 cups. Most organisers cannot store, transport or budget for that volume on a one-trip basis, which is where deposit-return earns its keep.
Worked examples
- 5,000-cap one-dayer, four drinks per head, no wash: 20,000 cups. Order 22,000 to cover breakage and souvenir loss (10%).
- 20,000-cap three-day festival, five drinks per head per day, on-site wash with two-cycle rotation: drink count is 300,000, but with cups cycling twice a day plus a 1.3 buffer for wash queueing, you need around 60,000 in circulation. Order 65,000 to allow for shrinkage.
- 50,000-cap weekend, six drinks per head per day, deposit-return scheme with three-cycle rotation: drink count is 900,000, circulating pool needed is roughly 130,000. Order 140,000 to absorb loss and souvenir take-home.
That 130,000 figure for a 50k weekender is the eye-opener. It is well under three cups per ticket, despite serving 18 drinks across the run, because each cup gets used six or seven times.
The deposit-return maths that fund the cup buy
Charge £2 per cup as a deposit. Industry redemption sits between 60% and 75% on a well-signposted scheme. Plenty of guests will keep the cup as a souvenir. That retained deposit is yours. Run the numbers on a 20,000-cap weekend with a printed cup at, say, £0.55 per unit. Cup cost is around £36,000 across a 65,000-cup order. With 35% non-redemption on the £2 deposit and a circulating pool of 60,000, retained deposits land near £42,000. The cups have paid for themselves with margin to spare, and you still own the inventory for next year. The deposit-return piece walks through this in detail.
What changes the rotation rate
Three operational decisions move the rotation number more than anything else. First, the wash facility itself. A trailer-mounted commercial dishwasher line can clean 5,000 to 10,000 cups an hour. Hand-washing kills the whole model. Second, deposit value. Below £1 redemption drops sharply because people cannot be bothered. £2 is the sweet spot we see, £3 maximises return but lengthens redemption queues. Third, the redemption process itself. Self-service token machines beat staffed bars for throughput by a wide margin.
Lead time, ordering windows and contingency
For Eco Saver tier pricing (our cheapest), you need 25 working days from artwork sign-off, so a midsummer event needs artwork signed off in April at the latest. Standard tier runs on 10 working days, useful for late additions. Plain UKCA-marked unbranded stock ships in 5 working days, so it works as your insurance buffer if attendance forecasts move up in the last fortnight. Most experienced festival teams place 90% of their order on Eco Saver early and hold a 10% buffer on unbranded stock for late top-ups.
Where to start
Send us your attendance forecast, days, drink projection and whether you have wash on-site. We can model the rotation in 10 minutes and quote both a single-trip and a deposit-return version so you can see the cost delta. Use the cup range to pick the format, or call 01642 615757 for a full plan.
