I have added more finance tutoring videos to the site! Check out my Store to select any videos you would like to purchase. I have videos on time value of money, showing how to calculate a basic stream of cash flows net present value, a typical investment or project net present value, the net present value of an annuity and the net present value of a perpetuity. There are other videos on a few key concepts in finance, including how to calculate the Weighted Average Cost of Capital and explaining with an example the Capital Asset Pricing Model. I will be adding more and more finance videos to help you learn finance concepts quickly and easily, and at a fraction of the cost of getting a tutor. All of the finance videos are $2 each, and once you purchase using Paypal you are able to immediately download and watch the video so you can get the help in finance you need right away. Take Me to the Store.
