Final and intermediate goods
A final good is purchased for final use in the period. Intermediate goods are inputs used to produce other goods. Count final output, or value added at every stage, to avoid double counting.

Core ideas
Key concepts
Domestic and national
Domestic aggregates are measured within the economic territory. National aggregates add residents’ factor income from abroad and subtract factor income earned domestically by non-residents.
Gross and net
Net aggregate = gross aggregate − consumption of fixed capital (depreciation). Depreciation is the estimated loss of value of fixed assets through normal use and obsolescence.
Market price and factor cost
Market price includes net indirect taxes. Factor cost reflects payments to factors. Net indirect taxes = indirect taxes − subsidies; factor cost = market price − net indirect taxes.
What national accounting measures
National income accounting records the value of production, income generated and expenditure on final output during a period, normally a year. In a simplified closed economy, production creates factor income and that income finances expenditure. The three views describe the same circular flow; differences in practice arise from data gaps and measurement conventions.
Product / value-added method
For each producing unit, value added = value of output − intermediate consumption. Sum domestic value added across sectors, then apply the required domestic/national, gross/net and market-price/factor-cost adjustments.
Income method
Add factor incomes generated by current production: compensation of employees, rent, interest, profit and mixed income of self-employed. Exclude transfer receipts because they are not payment for current production.
Expenditure method
GDP at market price = private final consumption + government final consumption + gross domestic capital formation + exports − imports. Imports are subtracted because they are included in spending but produced abroad.
Careful classification prevents errors
- Count only current production; exclude second-hand asset sales, but include the current service charge of an agent who arranges the sale.
- Exclude pure financial transactions such as buying shares; include brokerage services.
- Exclude transfer payments such as scholarships or pensions from current factor income, while counting the output purchased with recipients’ spending.
- Include change in inventories as investment; unsold output is still produced in the period.
- Imputed rent for owner-occupied housing is included where the national-accounting convention requires it.
Conversions among aggregates
NDPMP = GDPMP − depreciation
GDPFC = GDPMP − net indirect taxes
GNPMP = GDPMP + net factor income from abroad
NNPFC (traditional national income) = GNPMP − depreciation − net indirect taxes
GDPFC = GDPMP − net indirect taxes
GNPMP = GDPMP + net factor income from abroad
NNPFC (traditional national income) = GNPMP − depreciation − net indirect taxes
Use the exact aggregate requested. Move from domestic to national with net factor income from abroad; move from gross to net by subtracting depreciation; move between market price and factor cost by adjusting net indirect taxes.
Worked calculation
Suppose GDP at market price is ₹1,000 crore, depreciation ₹80 crore, net indirect taxes ₹60 crore and net factor income from abroad −₹10 crore.
- NDP at market price = 1,000 − 80 = ₹920 crore.
- GDP at factor cost = 1,000 − 60 = ₹940 crore.
- GNP at market price = 1,000 − 10 = ₹990 crore.
- NNP at factor cost = 990 − 80 − 60 = ₹850 crore.
Nominal GDP, real GDP and welfare
Nominal GDP values output at current prices; real GDP values it at base-year prices to isolate volume change. GDP deflator = (nominal GDP ÷ real GDP) × 100. A rise in nominal GDP can reflect prices, quantities or both. GDP per capita is an average, not a description of distribution; unpaid work, leisure, environmental costs and quality differences also limit GDP as a welfare measure.
Exam practice
Try these original questions
- Why is the value of intermediate goods not added separately when final output is counted?
- Calculate NNP at factor cost when GDP at market price is ₹2,400 crore, depreciation ₹150 crore, net indirect taxes ₹200 crore and NFIA ₹30 crore.
- Classify a pension transfer, a broker’s fee on a second-hand house sale, and an unsold finished product.
Review points
For the calculation: GNP at market price = 2,430; NNP at factor cost = 2,430 − 150 − 200 = ₹2,080 crore. A pension is a transfer; the broker fee is current service output; unsold output enters inventory investment.
