What is Net Investment?
Net investment refers to the total amount businesses spend on acquiring new capital assets (such as machinery, buildings, or technology) after subtracting depreciation. It reflects the real increase in an economy’s productive capacity and is a key indicator of long-term growth.
Definition
Net investment is the value of gross investment minus depreciation, representing the actual addition to a company’s or country’s capital stock.
Key takeaways
- Measures capital growth: Shows whether productive capacity is increasing.
- Accounts for wear and tear: Subtracts depreciation from gross investment.
- Economic growth indicator: Higher net investment drives future output.
- Used in national accounts: Represents capital formation in GDP.
- Business performance signal: Indicates expansion or modernization.
Formula
Net Investment = Gross Investment – Depreciation
Example:
- Gross investment: P5,000,000
- Depreciation: P1,200,000
Net Investment = 5,000,000 – 1,200,000 = P3,800,000
