The four cost items
- Licence per month: a fixed price, a price per member or a price per member band.
- Fee per debit or online payment: in the Netherlands usually between € 0.25 and € 0.50 per transaction.
- Setup and switching: sometimes free, sometimes a fixed amount or hours at an hourly rate.
- Add-ons: an own app in the app stores, access gates, extra staff or a till.
What the market charges
In October 2026 we put the pricing pages of five Dutch packages side by side. Entry plans for small studios start around €39 to €99 a month. Packages with everything in cost €150 to €600 a month. One big package only gives a price after a quote. Per debit or online payment they charge € 0.25 to € 0.50, and yearly contracts occur.
The overview per package, with source and date, is on compare gym software.
The maths: 100, 200, 400 and 800 members
The formula is always: monthly price + number of debits × fee per debit + add-ons. For Hiigym, with one debit per member per month:
| Members | Plan | Mollie | Total per month | Per member |
|---|---|---|---|---|
| 100 | Studio €99 | €35 | €134 | €1.34 |
| 200 | Studio €99 | €70 | €169 | €0.85 |
| 400 | Gym €149 | €140 | €289 | €0.72 |
| 800 | Club €299 | €280 | €579 | €0.72 |
If a package charges € 0.50 per debit instead of € 0.35, you pay €30 a month more at 200 members, apart from the licence.
Ask about the costs you do not see
- Is there a fee on every debit, on top of the payment provider?
- Does the price go up with every member or per band?
- Does an app in your own brand cost extra?
- What does the switch cost, and who does it?
- Do you sign for a year, or can you stop monthly?
- Do you pay per extra staff member?
