The following is my view on what the ministerial salary revision should look like and is calculated by using the table above as the base (the table is found HERE).
The MPs monthly salary should be calculated by averaging:
1 - 10th of Employed Household by Decile: $1400
41 - 50th of Employed Household by Decile: $5888
91 - 100th of Employed Household by Decile: $23684
(1400+5888+23684)/3 = $10324
Annual income: $10324 X 13 months = $134,212
The monthly salary for Ministers and Senior Parliamentary Secretaries should be calculated by multiplying $10324 (salary for MPs) by the average of real annual change in percentages for the:
1 - 10th of Employed Household by Decile: 4.9%
41 - 50th of Employed Household by Decile: 7.1%
91 - 100th of Employed Household by Decile: 4.1%
4.9+7.1+4.1 = 5.4%
10324 X 5.4 = $55750
Annual income: $55750 X 13 months = $724,750
The monthly salary for Administrative officers at SR9 superscale grade should be calculated by dividing 5.4% by 3 = 1.8%, and multiplying it by $10,324 = $18,583.
Annual income for AOs at SR9 grade: $18583 X 13 = $241,579
The monthly salary for the Prime Minister should be calculated as such:
(1.8 X 2) +5.4 = 9%
$10324 X 9 = $92,916
Annual income for the Prime Minister: $92916 X 13 = $1,207,908
The monthly salary for the President should be calculated as follows:
($92916 X 14)/13 = $100,063
Annual income for the President: $1,300,819
On top of this the MPs, AOs, Ministers, PM and President should also receive bonuses that are not higher than 3 times their monthly salary, reflecting the strength of the economy, as well as the performance and prospects of the nation in GDP, productivity growth, consumer price index and other relevant indicators.
