Sales growth shows the percentage increase in sales over the last year.
Sales growth is important because, as an investor, you want to know that the demand for a company's products or services will be increasing in the future.
It is important to distinguish however between organic sales growth and acquisitive growth. Growth rates differ by industry and company size. Sales growth of 5-10% is usually considered good for large-cap companies, while for mid-cap and small-cap companies, sales growth of over 10% is more achievable.
