What happens to npv when Cost of capital decreased?

When the cost of capital decreases, the net present value (NPV) of a project typically increases. This is because a lower cost of capital reduces the discount rate applied to future cash flows, making them more valuable in present terms. Consequently, projects that may have had a negative NPV at a higher discount rate could become positive, making them more attractive for investment. Overall, a decrease in the cost of capital enhances the potential profitability of investment opportunities.
