I am stumped on my last question which is using the discounted cash flow formula.... what effect will increase the required rate of return on the present value. I'm getting that it will be increased. Is this right?

Yes, your understanding is correct. Increasing the required rate of return will have a direct effect on the present value when using the discounted cash flow formula.

To understand why, let's briefly go over the discounted cash flow formula. The formula calculates the present value of future cash flows by discounting them back to the present using a discount rate, also known as the required rate of return. The discount rate represents the opportunity cost of investing in a particular project or investment. It reflects the return an investor could expect to earn if they invested their money elsewhere with similar risk.

When the required rate of return increases, it means that the investor's expectations for returns have become higher. As a result, the present value of future cash flows decreases because the higher discount rate reduces the value of those future cash flows. In other words, the higher the required rate of return, the less valuable future cash flows are in the present.

Conversely, if the required rate of return decreases, the present value of future cash flows will increase because the lower discount rate increases the value of those cash flows, reflecting the investor's lower return expectations.

So, in summary, an increase in the required rate of return will decrease the present value of future cash flows when using the discounted cash flow formula.
