Do not forget the Unlimited Apps option.
Monthly costs are 3 Apps for standard plan: 3*800 = 2400 euro, 3 times 500 users times 10 euro: 15000 euro. So a total of 17400 per month.
If you select the Unlimited Apps option: that is 2000 per month and 25 per user per month12500. Total is 14500 per month.
But you best talk to a sales representative of Mendix about this. Just go to https://www.mendix.com/contact-us/ and ask them.
