What Are Activity Ratios?
Activity ratios are financial ratios that measure how efficiently a company uses assets, inventory, receivables, payables, or working capital to generate sales. They are sometimes called efficiency ratios or turnover ratios.
These ratios help readers move beyond profit alone. A company can report rising sales while tying up too much cash in inventory, collecting receivables slowly, or using assets inefficiently.
Key Takeaways
- Activity ratios measure operating efficiency and asset use.
- Common examples include inventory turnover, receivables turnover, payables turnover, and asset turnover.
- They are most useful when compared with industry peers and the company's own history.
- Higher is not always better; very high turnover can signal underinvestment or supply strain.
- Activity ratios should be read with margins, cash flow, and working-capital trends.
Common Activity Ratios
Ratio | What it shows |
|---|---|
Inventory turnover | How quickly inventory is sold or used. |
Receivables turnover | How quickly customers pay. |
Payables turnover | How quickly the company pays suppliers. |
Asset turnover | How much revenue is generated per dollar of assets. |
Working-capital turnover | How efficiently working capital supports sales. |
How to Read Them
Activity ratios are diagnostic. A falling receivables turnover ratio may suggest slower collections, looser credit terms, customer stress, or a change in sales mix. A falling inventory turnover ratio may point to weaker demand, obsolete stock, or intentional inventory buildup.
Context decides the interpretation. Grocery retailers naturally have high inventory turnover. Heavy manufacturers and utilities may have lower asset turnover because they require large fixed assets.
Example
If a company has $10 million in annual sales and average total assets of $5 million, its asset turnover ratio is 2.0. That means the company generated $2 of sales for each $1 of average assets. Whether that is strong depends on the industry and capital intensity.
Where They Can Mislead
Activity ratios can improve for unhealthy reasons. A company may boost inventory turnover by carrying too little stock, leading to lost sales. It may stretch payables to conserve cash, damaging supplier relationships. It may sell assets to improve turnover while weakening future capacity.
The Bottom Line
Activity ratios show how efficiently a company turns operating resources into sales. They are most powerful when they are tracked over time, compared with peers, and interpreted alongside cash flow and profitability.
