The verdict in three sentences
For a chain of 6 gyms and 7,500 members, licence cost is not the real issue: the 4% monthly churn rate is what destroys value. A custom member app, connected to recurring ACH and card billing, class booking and turnstiles, spots members who are drifting away and re-engages them before they leave. A realistic 2026 budget sits between 45,000 and 80,000 USD, delivered in 4 to 6 months.
Off-the-shelf software or custom app
Club management software charges per location per month, with paid add-ons for a branded app, marketing and access integrations.
| Item (2026 order of magnitude) | Off-the-shelf software | Custom app |
|---|---|---|
| Licence | 300 to 550 USD per location per month | 0 USD |
| Annual cost for 6 locations | 21,600 to 39,600 USD | 0 USD |
| Initial development | 0 to 3,500 USD setup | 45,000 to 80,000 USD |
| Maintenance and hosting | included | 8,000 to 12,000 USD per year |
| Branded app | add-on, 175 to 350 USD per month | included, iOS and Android |
| Churn risk score | rarely available | native, based on attendance |
| Ownership of member data | limited export | full |
| Cumulative 4-year cost | 86,000 to 175,000 USD | 77,000 to 128,000 USD |
The gap on licences alone is modest. It becomes decisive once you add retention, personal training upsell and the freedom to evolve the tool.
The modules that cut churn
| Module | Function | Measurable effect |
|---|---|---|
| Memberships and recurring billing | ACH and card on file, billing cycles, failed payment retries | failed payments from 3% to 1% |
| Class booking | schedule, caps, waitlist, push reminders | class fill rate from 65% to 85% |
| Turnstile integration | QR code or NFC badge, multi-site access, hours by plan | access fraud near zero |
| Drift score | alert when a member drops from 3 visits to under 1 a week | churn from 4% to 3.2% a month |
| Upsell | personal training, class packs, online shop | 6 to 10% extra revenue |
| Chain dashboards | attendance by gym and hour, revenue, cancellations | staffing and hours decisions |
| Compliance | New York online cancellation rules, FTC click-to-cancel guidance, privacy | regulatory risk under control |
New York requires gyms to offer an easy cancellation path: design it to propose a freeze or plan change before final confirmation.
Timeline and budget by phase

| Member app and booking | 6 weeks | 13,500 to 25,000 USD |
| Access control and turnstiles | 3 weeks | 7,000 to 11,500 USD |

Mini case study
Marcus, founder of a 6-gym chain in New York, has 7,500 members paying 59 USD a month on average. At 4% churn he loses 300 members every month. The drift score and outreach bring that rate down to 3.2%, so 60 members kept each month. Over the year, 720 members stay on average 4 months longer: 720 x 4 x 59 = 169,920 USD. Add 30,000 USD of licences removed. Against 62,000 USD of development and 9,000 USD of maintenance, the net first-year gain reaches 128,920 USD.

FAQ
How much does a custom app for a gym chain cost?
Budget 45,000 to 80,000 USD for 3 to 10 locations, with memberships, recurring billing, booking, mobile app and access control. Maintenance runs 8,000 to 12,000 USD a year.
Are our current turnstiles compatible?
Most controllers on the market accept integration via API or relay, about 3 weeks and 7,000 to 11,500 USD. Hardware replacement costs roughly 4,500 to 9,000 USD per entrance.
How do we migrate existing payment methods?
Your payment processor can transfer stored cards and bank details securely to the new account, so the 7,500 members do not have to re-enter anything.
What does recurring billing cost?
With a payment processor, expect about 0.8% capped at 5 USD per ACH debit and around 2.9% + 0.30 USD per card charge.
Can members cancel online?
Yes, and New York rules push in that direction. The flow first offers a 1 to 3 month freeze, which retains 15 to 25% of requesters on average.
