Net Present Value (NPV) is a financial metric used to evaluate the profitability of a project or investment by calculating the present value of expected future cash flows. In business decision-making, NPV helps clients determine whether an investment is worthwhile by comparing its potential returns to the cost of the investment. The Internal Rate of Return (IRR) is another important metric that calculates the rate at which the NPV becomes zero. IRR indicates the rate at which the project's profitability grows and can help clients make informed decisions about investments. By combining these metrics, businesses can make data-driven decisions about whether to invest in a particular project or opportunity.
