Personal income = Net domestic product at factor cost + Net factor income from abroad + (Interest received by households – Interest paid by households) + Transfer income – Corporate tax – Undisbursed profit.
Therefore, – PI = 8000 + 200 + (1500 – 1200) + 300 – 500 -1000
= 8000 + 200 + 300+300-500-1000
= 7300
Personal Disposable Income = Personal Income – Personal Tax Therefore PDI
= 7300 – 500
= 6800.
