How much profit the business makes on each dollar invested in it. Higher is better.
What is left of each sale after the cost of making the product. A high number often means pricing power.
The cash the business earns for its owners, compared with the price of the whole company.
How fast sales grew each year over the last five years.
How many years of today's profit you pay for at today's price. Lower means cheaper.
How much the company owes compared with what it owns outright. Lower is safer.
