How is nnp calculated?

Net National Product (NNP) is calculated by taking the Gross National Product (GNP) and subtracting depreciation (the loss of value of capital goods over time). GNP measures the total value of goods and services produced by a nation's residents, regardless of where the production occurs. Depreciation accounts for the wear and tear on capital assets, providing a more accurate reflection of a nation's economic performance. The formula can be expressed as NNP = GNP - Depreciation.
