Cost percentage
Cost percentage := this is a percentage of the median monthly cost of living. E.g. if a fee is defined as 10% cost percentage and the current monthly median cost of living is 1'000 units, then the actual fee to be paid is 100 units. And if next month, the monthly median cost of living will be 1'030, then the actual fee will be 103 units. The StableState uses cost percentages to define all kinds of monetary amounts that must adapt to inflation or deflation. (Although, the StableState has rules in place to minimize inflation, it cannot be totally avoided)
