GDP – depreciation = NDP
What’s depreciation (aka. consumption of fixed
capital)?
• Repairing, maintaining, and replacing capital

• Personal income minus personal income
tax = disposable income (DI)
IMPORTANT POINT TO
REMEMBER
• THIS IS IN YOUR BOOK!
• WAGES, INTEREST, RENT, AND PROFITS
ARE ALSO INCLUDED IN GDP
CALCULATIONS BUT NOT IN THE
EXPENDITURE APPROACH (C+Ig+G+Xn)
• THEY ARE COUNTED IN THE INCOME
APPROACH
• If you are calculating GDP, ignore types of
income and just focus on expenditures
