Opportunity cost is the value of the next best alternative that is forgone when making a decision. For example, if a company uses cash (a current asset) to purchase inventory instead of investing it in a savings account, the opportunity cost is the interest income that could have been earned from the savings account.
Turnover ratios measure how efficiently a company uses its assets. Examples include:
1. **Inventory Turnover Ratio**: Indicates how many times inventory is sold and replaced over a period.
2. **Accounts Receivable Turnover Ratio**: Measures how effectively a company collects its receivables.
3. **Current Asset Turnover Ratio**: Shows how efficiently a company generates sales from its current assets.
