Capital investing is measuring the returns from an investment in capital in terms of: - Time: How long do I get my money back? - Value of Return: How much money will I make overtime? Capital investing is important as it usually involves large amounts of money, so we want to make sure we are making the right decision for the business. Think about a big purchase you will make in your own life, such as your first car. 

Automatically, you're already thinking the following: 

• How much will it cost me? (Capital investment) 

• How long it will last? (Useful Life) 

• What benefits will I receive over time? (Value of return) 

For the last point, benefits are not the same as well, the return you will get will depreciate over time as the older the car, the more work it has to be done, less sex appeal of the car and other factors. Likewise, for a business, the cash benefits from machinery are likely to reduce overtime. For this section we explore two different capital investment tools: - Payback Period: Measure of return in terms of time - Net Present Value: Measure of returns in value.
