An increasing Sales to Administrative Expenses ratio is generally a positive sign, showing the company is more able to generate sales using its Sales General and Administration Expenses. Rarely does a company's performance suffer from administrative expenses being too small.
Hiring based on sales forecasts that turn out to be lower than expected, corporate mergers, and rapid growth phases tend to leave the company with a disproportionately high percentage of administrative expenses - often primarily consisting of salaries and benefits of the administrative staff.
Too much administrative overhead can indicate an overly complex managerial structure, redundant departments, and slow reaction to market changes. Keeping track of this ratio over time will yield a clearer picture of how the company keeps control of its administrative expenses, and comparing this ratio to competing companies provides even more insight.
