Determining Value
Let's say that you want to start a business, and you decide to open a restaurant. You go out and buy a building, buy all the kitchen equipment, tables and chairs that you need, buy your supplies and hire your cooks, servers, etc. You advertise and open your doors.
Let's say that:
* You spend $500,000 buying the building and the equipment.
* In the first year, you spend $250,000 on supplies, food and the payroll for your employees.
* At the end of your first year, you add up all of the money you have received from customers and find that your total income is $300,000.
Since you have made $300,000 and paid out the $250,000 for expenses, your net profit is:
$300,000 (income) - $250,000 (expense) = $50,000 (profit)
At the end of the second year, you bring in $325,000 and your expenses remain the same, for a net profit of $75,000. At this point, you decide that you want to sell the business. What is it worth?

One way to look at it is to say that the business is "worth" $500,000. If you close the restaurant, you can sell the building, the equipment and everything else and get $500,000. This is a simplification, of course -- the building probably went up in value, and the equipment went down because it is now used. Let's just say that things balance out to $500,000. This is the asset value, or book value, of the business -- the value of all of the business's assets if you sold them outright today.
