Gross National Product (GNP) measures the total value of output/income attributable to a country's residents before accounting for the wearing out of capital equipment (machinery, buildings, vehicles) used up in producing that output.

Depreciation (also called consumption of fixed capital) is the estimated value of capital assets used up during the year. Because using up capital is a genuine cost of production — the capital stock must eventually be replaced — a net measure of income deducts it:

NNP=GNP−DepreciationNNP = GNP - \text{Depreciation}

NNP at Factor Cost is the technical definition of National Income. It is regarded as the most accurate single measure of the income genuinely available to a country's residents, because it neither overstates output by ignoring capital wear (as GNP does) nor includes indirect taxes that are not a factor's income (handled through the market-price/factor-cost distinction).

✓Final answer

NNP = GNP minus Depreciation; NNP at factor cost is the technical definition of National Income.
