Ratings Central and Zermelo are not free. Ratings Central uses a pay-what-you-think-is-fair fee system. The cost for Zermelo depends on whether you are using it in conjunction with Ratings Central.
Different people use Ratings Central in different ways. Some directors have only a few players, a few matches, and an occasional event. Others have many players, many matches, and many events and tournaments. Some directors and clubs are independent. Others are part of larger organizations. Some clubs and organizations have many directors. Others have only one. Some use Cantor and Zermelo. Others use some other method of submitting results. Some grab data from the website for download or redisplay.
Rather than try to accommodate all the different ways that people use Ratings Central in a fee schedule, Ratings Central uses a pay-what-you-think-is-fair fee system: Each year that you, an event director, submit events to Ratings Central, you should pay what you think is fair, taking into account how you, your players, and your club or organization use Ratings Central.
For purposes of determining what you owe, “submit events to Ratings Central” means submit events that were not already in the system. So, if all you do during the year is resubmit events (e.g., to make corrections) that were already submitted in a previous year, then you do not owe anything for that year.
If you are part of a club, organization, or some other entity that has multiple event directors, then you (the event directors) can pay as a group. If you think that your players should contribute, then you should collect the money from them. That is, directors should handle the payments, but directors can decide how they raise the money within their club, organization, or tournament.
What you should pay should include what you think is fair for the use of all aspects of Ratings Central, including the ratings, website, Cantor, Zermelo, the API, notification emails, etc.
Please pay in January for the previous calendar year. When paying, please tell us the calendar year, director IDs, and club IDs that you are paying for.

We are not going to tell you how much you should pay each year to use Ratings Central (where “you” includes the clubs and organizations that you represent). If you are not sure how to determine what is fair, the following may help: What is the most that you would pay to avoid the alternative of not using Ratings Central? You should not pay more than that. On the other hand, that is probably more than you feel comfortable paying. So, come up with an amount that you feel is reasonable and fair. You should be able to say to yourself, “I’m getting a good deal. I’d be willing to pay 50% or 100% more for what I get.” But, if you can say, “Wow. I’m only paying 5% of what I’d be willing to pay”, then do you think that is fair?
If you think that it is fair to pay nothing, then apparently Ratings Central is of no value to you, so you should not be using it.
