How do you calculate the domain pricing overpayment?

Pricing History:

• 24 February 2010 – Article 19A purportedly changed by Special Resolution using Weighted Voting, so that the power to change domain name prices moved from members to the board. If weighted voting breaks the law, then this change is likely void. So the ability to change domain name prices would never have moved from the membership and changes to prices made by the board would be invalid.

• 1st March 2016 – Base wholesale .uk price raised from £2.50 to £3.75 a year.
  
  £1.25 rise per multi year or a 50% increase.

• 13th January 2020 – Base wholesale .uk price raised from £3.75 to £3.90 a year.
  
  £1.40 total rise per multi year.

Over this timeframe, average number of .uk domains was around 11.1 million a year.

Overpayment Calculation

11.1 million domains times £1.40 = £15,540,000

Three years at that rate = £46,620,000

11.1 million domains times £1.25 = £13,875,000

Three year at that rate = £41,625,000

Total Overpayment in Past Six Years = £88,245,000

Ongoing Annual Overpayment = £15,540,000

Estimate Your Own Overpayment

Multiply your domains under management by £1.33

Then multiply by either 6 years or your length of membership

Your ongoing annual overpayment would be your Domains Under Management times £1.33
