## Efficiency ratios - use and calculation

### Use of the ratios

The individual ratio for a single year is of limited value. What are important are trends over time and comparisons with other firms in the same industry. These ratios are very industry specific.

As always, you need sets of ratios for a series of years, plus the corresponding information for the competition to really get value from the exercise.

### Improving the ratios

Remember, there is little point in improving ratios as such. It is the business that is being improved, and the ratio values will reflect this improvement.

**Asset turnover**: Get sales up, assets down, or a combination of both.**Stock turnover**: Get sales up, stock down, or a combination of both.**Debtor days**: Get debtors down, sales up, or a combination of both.

Remember, ratios are like symptoms of a disease (or of health). You get nowhere treating symptoms; you must get to the root of the problem.
