A typical market basket of goods and services is used to figure out the Consumer Price Index (CPI). It compares how much they cost this month to how much they cost one month, one year, or ten years ago. The point in time in the past that is used to compare current prices to is called the “past period.”

When using the Net Present Value (NPV) method to judge a project, a positive PW(i) means that the project will likely lose money when the time value of money is considered. That is, more than the project’s future profits would be needed to cover the initial cost and the wanted return. Because of this, such a project would usually be turned down. Conversely, a negative PW(i) indicates a high likelihood of profitability and a return that meets or exceeds expectations. In this case, the project has a good chance of being approved.

It is also known as the required rate of return or the minimum attractive rate of return (MARR). They both mean the lowest return an investor is willing to take on an investment, taking into account the risk and other possible opportunities.

Over time, the net cash flow of an investment project can help us put it into a category. We specifically keep track of how many times the cash flow changes from negative (money spent) to positive (money gained) or from positive to negative (money gained). We do not count times when there is no cash flow. The project’s cash flow changes more and more as these switches happen.
