Trampoline Park Card Fees: $1.14 a Visit, $72,000 a Year
A family books a 90-minute pass at Altitude Arlington online. The ticket lists at $19.99. A flat-rate processor keeps $0.88 of it, which is 2.9 percent of the price plus a fixed 30 cents per transaction. The park sold a ticket at full price, yet 4.4 percent of the sale never reaches the ledger.
Card processing is the quietest cost line in a trampoline park P&L. Rent gets a row in every pro forma. Labor gets several. Insurance got an entire trade-association program. Payment fees usually sit buried inside a merchant-services or bank-charges line, reviewed once a year when the statement arrives.
They deserve better, because the fee has a structure that rewards attention. It is not a flat percentage. It is a percentage plus a fixed charge per transaction, and at typical park ticket sizes the fixed charge is between a quarter and a third of the total fee. That single fact drives almost every optimization in this article.
This article prices the line using published, checkable rates: Stripe and Square US pricing, the Helcim fee disclosure, the Federal Reserve debit interchange cap, and the European Union interchange regulation. The reference box is the one used throughout this series: 31,512 sq ft (2,928 m²) at 2.0 visits per sq ft, which is 63,024 admissions a year. All figures are in US dollars unless marked otherwise.
1. Anatomy of a Flat-Rate Card Fee
Two US processors publish their consumer rates openly, which makes them useful anchors even though no park is obligated to use them. Stripe charges 2.9 percent plus $0.30 for a domestic card payment made online. Square charges the same online and 2.6 percent plus $0.10 when a card is tapped or dipped in person. Helcim, an interchange-plus processor, adds a smaller markup on top of the raw network cost instead of a blended rate.
The fixed component is what people misjudge. On a $19.99 ticket, the 30 cents is 1.5 percent of the sale by itself and 34.1 percent of the total fee. On the $29.08 average check-in derived below, it is 26.2 percent of the fee. On a $349.99 party it barely matters. Small transactions subsidize the fixed charge; large ones dilute it.
| Rail | Published rate | Notes |
|---|---|---|
| Stripe, online card (US) | 2.9% + $0.30 | Domestic cards; +0.5% keyed-in; +1.5% international |
| Stripe, ACH bank debit | 0.8%, $5.00 cap | Capped fee, so large invoices cost $5.00 flat |
| Stripe, dispute | $15.00 each | Returned if you win |
| Square, in-person card | 2.6% + $0.10 | Tap, dip or swipe |
| Square, online card | 2.9% + $0.30 | Invoices price at 3.3% + $0.30 |
| Square, card on file | 3.5% + $0.15 | Applies to saved-card recurring billing |
| Square, ACH (invoice) | 1%, $1 min, $10 cap | Bank transfer on invoices |
| Square, Afterpay (BNPL) | 6% + $0.30 | Merchant paid in full up front |
| Helcim, online card | Interchange + 0.50% + $0.25 | Base tier below $50k monthly volume |
| Helcim, ACH | 0.5% + $0.25, $6 cap | No monthly fees |
| Helcim, chargeback | $15.00 | Refunded when the merchant wins |
These are list prices as published and accessed in October 2026. Processors negotiate below them at volume, and venue-management platforms bundle processing differently. Treat the table as the visible ceiling of the market, not the floor.
2. The Product Ladder: Where the Fee Percentage Peaks
Apply the flat online rate, 2.9 percent plus $0.30, across the product ladder a park actually sells. The anchor prices come from published pages: the $19.99 90-minute pass and $24.99 120-minute pass on the Altitude Arlington location site, the $11.99 weekday junior session at the same park, the $349.99 ten-guest birthday package on the Urban Air Port Richey party page, and the $4.99 grip sock price used in our grip sock revenue analysis. The $29.08 average check-in is derived from the Lelantos Holdings monthly disclosure: $243,079.27 in total revenue divided by 8,360 check-ins at the McAlester park in July 2026.
| Product line | Price | Fee at 2.9% + $0.30 | Fee as share of line |
|---|---|---|---|
| Grip socks, sold alone | $4.99 | $0.44 | 8.9% |
| Weekday junior session | $11.99 | $0.65 | 5.4% |
| 90-minute pass | $19.99 | $0.88 | 4.4% |
| 120-minute pass | $24.99 | $1.02 | 4.1% |
| Average check-in (derived) | $29.08 | $1.14 | 3.9% |
| 10-guest birthday package | $349.99 | $10.45 | 3.0% |
| Same package on invoice | $349.99 | $11.85 | 3.4% |
Read the table from top to bottom and the pattern is clear: the percentage cost of accepting payment is highest exactly where the park earns least. A standalone sock sale hands over nearly 9 cents of every dollar. The party booking, the park’s highest-value transaction, loses only 3 percent.
One structural fix follows immediately. If the sock is added to the same cart as the ticket, the transaction is $24.98 and the fee is $1.02. Sold as two separate transactions, the fees are $0.88 plus $0.44, or $1.32. Bundling saves the second fixed charge, 30 cents, on every guest who would otherwise split the purchase. At 63,024 visits, the theoretical maximum of that one rule is $18,907 a year, though real-world attach rates make the attainable figure smaller.
Why this line matters: card fees scale with revenue, so they hide inside percentage thinking. Converting them to dollars per admission, $1.14 on the average check-in, makes them comparable with labor and rent, which are also per-visit costs.
3. The Annual Line: $72,000 at Reference Scale
Now run the number annually. The reference box does 63,024 admissions at the derived $29.08 average check-in, which is $1,832,738 of card volume if every visit is card-paid. Split the flat fee into its two components and compute each one separately:
Fee per visit = $29.08 x 2.9% + $0.30 = $0.84 + $0.30 = $1.14 Annual variable component = $1,832,738 x 2.9% = $53,149 Annual fixed component = 63,024 x $0.30 = $18,907 Annual total = $53,149 + $18,907 = $72,056
Call it $72,000 a year, or $1.14 per admission. For scale, that is almost exactly the annual cost of one supervision post at BLS wage rates, which we calculated at $72,389 in the labor cost per square foot analysis. A park that recruits hard to control headcount is simultaneously donating a second invisible post to its processor.
| Item | Formula | Result |
|---|---|---|
| Annual card volume | 63,024 visits x $29.08 | $1,832,738 |
| Flat-rate fee, variable | $1,832,738 x 2.9% | $53,149 |
| Flat-rate fee, fixed | 63,024 x $0.30 | $18,907 |
| Flat-rate fee, total | Sum of both | $72,056 |
| Fee per admission | $72,056 ÷ 63,024 | $1.14 |
| Interchange-plus, total | $1,832,738 x 2.31% + 63,024 x $0.25 | $58,092 |
| Annual saving, IC+ vs flat | $72,056 − $58,092 | $13,965 |
Every point of cash or alternative settlement that the published rate does not cover changes this total proportionally. If 20 percent of visits settle by a cheaper rail, the line drops by roughly $14,400. If the park is busier than the reference box, it scales up the same way. The formula, not the absolute figure, is the deliverable.
4. Flat Rate vs Interchange-Plus: The Volume Crossover
Flat-rate pricing buys simplicity: one number, no statement archaeology, no monthly fee. Interchange-plus pricing buys transparency: the merchant pays the raw network interchange plus a published markup, and the markup falls as volume grows. Helcim discloses both its markup tiers and a blended average of 2.31 percent plus $0.25 per online transaction, which is the figure used in the table above.
At reference scale the comparison is one-sided. The park processing $152,728 of card volume per month ($1,832,738 ÷ 12) sits comfortably inside Helcim’s $100k-to-$500k tier, where the online markup falls to 0.35 percent plus $0.20. Our saving estimate of $13,965 uses the more expensive base-tier markup, so it is conservative.
The honest caveat cuts the other way too. The 2.31 percent average depends on card mix. A park full of rewards credit cards pays more interchange than one full of basic debit, and interchange-plus passes that cost through without a cap. Flat rates do the opposite: they overcharge simple cards and absorb the cost of premium ones. Below roughly $25,000 of monthly card volume, the flat-rate premium is small in dollars and the simplicity is defensible. Above that, the spread between 2.9 percent and roughly 2.3 percent is real money and worth a quote.
Two processor features worth asking for by name: automatic volume discounts that reprice the markup tier without renegotiation, and Level 2/3 interchange optimization for business-card payments, which Helcim prices at 30 percent of the savings generated. Corporate and school cards are exactly where group bookings land, and their default interchange is among the highest in the network.
5. The ACH Lever for Group and Party Bookings
Bank-transfer rails are the least-used cost lever in this industry, because walk-in guests never choose them. That is fine: walk-ins are not the target. School field trips, corporate team events and sports-club bookings are invoiced transactions of $1,000 to $5,000, and they are the ones where the card rail hurts. A capped-fee ACH product turns the fee curve flat at a few dollars.
| Invoice size | Card at 2.9% + $0.30 | Stripe ACH (0.8%, $5 cap) | Square ACH (1%, $10 cap) |
|---|---|---|---|
| $200 deposit | $6.10 | $1.60 | $2.00 |
| $2,000 school group | $58.30 | $5.00 | $10.00 |
| $5,000 corporate event | $145.30 | $5.00 | $10.00 |
On a $2,000 booking, ACH saves $53.30 per transaction, a 91 percent reduction. On $5,000, the saving is $140.30. Set against the party economics we published in the party revenue per guest analysis, where an average booking already carries a host, room and cleanup cost, the payment rail is one of the few costs a group coordinator can change with an email.
The trade-offs are real and should be stated. ACH settlement takes one to three business days, so the cash arrives later than a card authorization. Consumers rarely adopt it voluntarily for small purchases, which is why this lever belongs on the invoiced, contracted side of the business. And failed debits generate their own return fees, so customer bank details must be verified before the booking is confirmed.
6. The Expensive Rails: BNPL, Card-on-File and Chargebacks
Three rails cost more than the standard online card fee, and each is growing in exactly the segment parks care about.
Buy now, pay later Square prices Afterpay acceptance at 6 percent plus $0.30. On a $19.99 ticket that is $1.50, or 7.5 percent of the sale, which is 1.7 times the standard card fee. On a $349.99 party it is $21.30. None of this means BNPL should be refused; it converts fence-sitters on large party deposits and it pays the merchant in full up front. It means the incremental volume it produces should be judged against a 6 percent marketing cost, not mistaken for a free payment option.
Saved-card recurring billing Memberships bill from a card on file, and Square prices that rail at 3.5 percent plus $0.15, higher than either the in-person or online rate. A $25 monthly membership costs $1.03 per billing cycle, 4.1 percent of the line. Five hundred members generate $6,150 a year in fees on that rail alone. Our membership pricing analysis showed members are the cash-flow backbone of a park; the billing rail they ride on deserves its own line item. Processors price dedicated membership billing more competitively than the generic card-on-file rate, so it is worth an explicit quote.
Chargebacks Both Stripe and Helcim charge $15 per dispute. That is the fee revenue of 17 walk-in ticket transactions, and the merchant also loses the ticket price unless the dispute is won. Helcim refunds its fee when the merchant wins; Stripe returns it too. The operational defense is documentation: signed waivers, timestamped check-ins and camera coverage, which parks maintain for safety reasons anyway. The $15 is small; the pattern of disputes is what triggers processor scrutiny and, eventually, higher rates.
7. Jurisdiction: Surcharging Rules and the US-EU Interchange Split
Whether the park can push any of this cost onto the guest depends on where the park stands.
In the United States, Visa caps a credit card surcharge at the lesser of 3 percent or the merchant’s actual cost of acceptance; Mastercard’s cap is 4 percent. Debit surcharging is banned outright under the Durbin Amendment. State law then layers on top: Connecticut, Massachusetts, Maine and Puerto Rico prohibit surcharges; Colorado and Oklahoma cap them at 2 percent; New York requires the full card-inclusive price to be posted before checkout. The Texas ban was struck down in federal court. The statutes move often enough that a park should confirm its own state with counsel before switching a surcharge on.
On the cost side, US debit interchange from large issuers is capped by Federal Reserve Regulation II at $0.21 plus 0.05 percent of the transaction plus a $0.01 fraud adjustment. On a $19.99 ticket that computes to $0.23, but only for issuers with more than $10 billion in assets; smaller issuers are exempt and charge more. Consumer credit interchange in the US is unregulated, which is why premium rewards cards cost so much to accept.
The European Union took the opposite route. Regulation (EU) 2015/751 caps consumer debit interchange at 0.2 percent and consumer credit at 0.3 percent, so the interchange on a €19.99 credit ticket is about €0.06. But the same framework, together with PSD2, prohibits surcharges on consumer cards across the EU and UK. The result is a mirror image: a US park pays more and may pass part of it on; a European park pays less and may pass on none of it. An EU operator’s fee optimization has to come from the processor negotiation, not from the guest.
Note the boundary of this comparison. Interchange is one component of the fee, not the whole; scheme fees and acquirer margins sit on top in every market. The caps constrain one layer, and the caps are what regulators actually publish.
Surcharges belong in the same per-ticket conversation as sales tax, which we computed city by city in the sales tax per ticket analysis. Both are small percentages that decide the real net price of a $19.99 ticket.
8. What the Data Does and Does Not Show
This analysis has visible seams, and they should be listed rather than papered over.
The rates are list prices. Stripe, Square and Helcim publish standard rates. A park on a venue-management platform, or one processing above $250,000 a year, can negotiate below them. Every dollar figure here is therefore an upper bound, not a quote.
The card mix is unknown. The interchange-plus comparison leans on Helcim’s own published average of 2.31 percent plus $0.25 online. Real parks will land above or below it depending on how many rewards credit cards walk through the door. No public dataset splits trampoline-park traffic by card type, and we will not invent one.
The 100 percent card-share assumption is convenient, not observed. Cash share at family entertainment centers is believed to be small and falling, but no operator publishes it. Each point of cash or alternative settlement reduces the fee line roughly proportionally.
The reference box is a convention. The 2.0 visits per sq ft on a 31,512 sq ft floor produced the 63,024-admission year used here. A quieter park scales down linearly; a party-heavy park scales up and pays less per dollar because the fixed fee dilutes.
Operators do not disclose this line. The most granular public park-level disclosure in the industry, the Lelantos monthly breakdown, reports six revenue categories and leaves 11.7 percent of revenue unattributed. Processing fees live somewhere inside residuals like that, which is precisely why nobody benchmarks them. Nothing in this article claims that fee levels cause revenue outcomes; the claim is only that the fee line is computable from public rates and larger than most budgets assume.
9. The Decision Rules
No forecasts here, just rules a park can apply to its own numbers.
1. Compute the line before negotiating it. Annual card volume times the blended rate, plus visit count times the fixed fee. If the total is under $10,000 a year, a flat rate is fine. If it crosses $30,000, request interchange-plus quotes with the tier schedule in writing.
2. Route invoiced groups through ACH. School, corporate and club bookings above roughly $1,000 cost $5 to $10 on capped ACH versus $29 to $145 on card. State the settlement delay in the booking terms and move on.
3. Bundle at checkout. Every split transaction pays another fixed fee. Socks, passes and add-ons belong in one cart; the difference is 30 cents per guest who would otherwise split the purchase.
4. Treat BNPL as marketing, not payments. At 6 percent plus $0.30 it is 1.7 times the card fee, and it should earn its place the way any promotion does.
5. Check the statute before surcharging. Allowed at up to 3 percent in most US states with disclosure, banned in a handful, capped at 2 percent in two, and prohibited across the EU and UK. Never on debit, anywhere.
6. Ask for Level 2/3 optimization on business cards. Corporate and school cards carry the highest interchange in the network, and the optimization exists precisely for them.
Planning a new park means pricing every recurring line before opening day, and payment processing is one of the few that a supplier conversation never covers. Our getting-started guide walks through the full budget stack from equipment to opening.
FAQ
How much does a trampoline park pay in card fees per ticket?
At the published flat rate of 2.9 percent plus $0.30, a $19.99 ticket costs $0.88 to accept, which is 4.4 percent of the sale. A $29.08 average check-in costs $1.14, or 3.9 percent. The percentage falls as the transaction grows because the fixed 30 cents is spread across a larger base.
What is interchange-plus pricing and when is it cheaper for a park?
Interchange-plus passes the raw card-network fee to the merchant and adds a fixed markup, such as Helcim’s published 0.50 percent plus $0.25 for online transactions. On its disclosed blended average of 2.31 percent plus $0.25, a park processing $1.83 million a year pays about $58,092 instead of $72,056, a saving of roughly $14,000 or 19 percent. Below about $25,000 of monthly card volume, the simplicity of a flat rate can be worth the difference.
Can a trampoline park charge customers a card surcharge?
In most US states, yes, up to 3 percent under Visa rules, with disclosure at entry, at the register and on the receipt. Connecticut, Massachusetts, Maine and Puerto Rico prohibit it; Colorado and Oklahoma cap it at 2 percent; New York requires the full card-inclusive price to be displayed. Debit surcharging is banned federally. In the EU and UK, surcharges on consumer cards are prohibited, so European parks recover costs through processor negotiation instead.
How can a park cut fees on large group bookings?
Invoice them on an ACH bank-transfer rail. A $2,000 school booking costs $5.00 through a capped ACH product versus $58.30 on card, a 91 percent reduction, and a $5,000 corporate event costs $5.00 to $10.00 versus $145.30. The trade-off is settlement time of one to three business days, which belongs in the booking terms.
Do chargebacks cost a trampoline park more than the processing fee?
Yes. Processors charge $15 per dispute, the fee revenue of about 17 walk-in ticket transactions, and the merchant also forfeits the ticket price unless the dispute is won. Signed waivers, timestamped check-ins and camera coverage are the practical defense, and some processors refund the fee when the merchant wins.
