So, fees will be reduced, given all this new income?  

The existing 7500 ISP customers fees are unchanged.  For the more than 8000 end-users customers, the fee structure change means they will now pay the same fees as ISPs (which is proportional to the total IPv4 and IPv6 number resources held.)  The prior end-user fees were a flat fee per number of address blocks regardless of size of each block, and this change results in all ARIN registry customers paying the same fees for the same services. 

The change will result in 4,800 of them paying more annually – although the majority of these will see an increase of $200 or less. (Larger organizations that have very significant IPv4 number resources bear the brunt of the increase, as the fee structure change putting them in parity with ISPs of similar resources means that some see rather substantial increase.) 

The remaining 3,200 end-user customers changing to the RSP fee schedule will pay less than they presently pay under the present end-user fee schedule as noted above. (Organizations that choose - for whatever reason - to maintain multiple relations with ARIN pay based on the total resources held under each, and that is indeed likely to be more than would result with consolidation.)   More details on the fee schedule are here - https://www.arin.net/announcements/20210712/
