Formulas
GDP = C + I + G + (X - M)
GDP (Gross Domestic Product) is the sum of consumption (C), investment (I), government spending (G), and net exports (X - M, where X is exports and M is imports). This formula calculates the overall economic output of a country.
Net Investment = Gross Investment - Depreciation
Net Investment measures the addition to capital stock, accounting for wear and tear (depreciation). Useful for assessing actual increases in productive capacity.
GNP = GDP + Net Factor Income from Abroad
Gross National Product (GNP) includes the total output produced by a country's factors of production, both domestic and abroad. It adjusts GDP to account for income from foreign investments.
NDP = GDP - Depreciation
Net Domestic Product (NDP) is the measure of the value of goods and services produced within a country after accounting for capital consumption. It reflects true economic output.
NNP = GNP - Depreciation
Net National Product (NNP) accounts for the total production by a country's factors of production and adjusts for capital depreciation, indicating the net income available.
National Income = NNP at Factor Cost
National Income represents the total income earned by a country's residents, including wages, rents, interests, and profits, reflecting the overall economic health.
Personal Income = National Income - Undistributed Profits - Corporate Taxes + Transfer Payments
Personal Income measures the income received by individuals and households, accounting for corporate taxes and undistributed profits not available to them.
Personal Disposable Income = Personal Income - Personal Taxes
Personal Disposable Income indicates the amount of income households have available for spending and saving after tax obligations.
Value Added = Output - Intermediate Goods
Value Added represents the contribution of each firm to the economy, calculated by subtracting the cost of intermediate goods from total output.
GDP Deflator = (Nominal GDP / Real GDP) × 100
The GDP Deflator is a measure of price inflation within the economy, comparing current market prices to constant prices to assess changes in goods and services output.
Equations
Net National Product (NNP) = Gross National Product (GNP) - Depreciation
NNP is derived by subtracting depreciation from GNP, reflecting the net output available to a nation's residents.
GDP = Sum of all final goods and services produced in a country during a year.
This defines GDP as the total monetary value of all final goods and services produced, used for assessing economic performance.
C + I + G + (X - M) = GDP
This equation encapsulates the expenditure approach to calculating GDP, encompassing consumption, investment, government spending, and net exports.
GNP = Σ(Wages + Rent + Interest + Profit)
This identity represents GNP as the sum of all incomes earned by residents from production, providing a comprehensive income measure.
Personal Disposable Income = Personal Income - Personal Taxes
This calculation reflects the amount individuals can devote to consumption or savings after tax deductions.
GDP Deflator = (Nominal GDP / Real GDP)
This equation quantifies the influence of price changes on GDP, serving as an essential tool for economic analysis.
NDP = GDP - Depreciation
NDP measures total output after accounting for capital wear and tear, giving a clearer indicator of effective production.
Net Factor Income from Abroad = Income received from abroad - Income paid to foreigners
This equation calculates the net income generated by a country's residents through overseas economic activity, vital for GNP determination.
National Income = NNP - Indirect Taxes + Subsidies
This adjustment to NNP gives the true income available to factors of production, factoring in government actions affecting income distribution.
Change in Inventories = Production - Sales
This equation determines how much inventory a firm has added or reduced in a fiscal period, indicating production versus sales dynamics.
