将来のキャッシュフローの正味現在価値を計算し、投資の妥当性を評価します。
In finance, a dollar today is worth more than a dollar tomorrow. This is the 'Time Value of Money' principle. When evaluating a long-term project or investment that will pay out over several years, you cannot simply add up the future cash flows; you must 'discount' them back to their value in today's dollars. Net Present Value (NPV) is the gold standard for this calculation. Our NPV Calculator allows you to input an initial investment and a series of future returns, applying a discount rate to show you if the project will actually create value after accounting for the cost of capital.
使い方
The tool takes each future cash flow and divides it by (1 + r)^t, where 'r' is the discount rate and 't' is the time period. It sums these 'Present Values' and subtracts the initial cost to arrive at the Net Present Value.
計算式
NPV = Σ [ CF_t / (1 + r)^t ] - Initial_Investment
Calculation Examples
1. **Project**: Invest $10,000 today. Get $4,000 for 3 years at a 10% discount rate. NPV = **-$53.34**. (Slightly losing money after accounting for time value).
Why use this tool in your daily life?
Think like a CEO. This professional-grade tool helps you evaluate long-term projects with the same rigor used by major corporations, ensuring you only commit resources to investments that truly build wealth.
