What is the Cash Ratio and What Does It Measure?
When corporate treasurers and credit rating agencies evaluate what is a cash ratio, they are testing worst-case solvency. Unlike broader liquidity ratios that assume a business can smoothly collect customer invoices or sell merchandise in warehouse inventory, the cash ratio asks: if all sales halted today and all creditors demanded payment immediately, could the business survive? By isolating purely liquid assets, the formula cash ratio provides an unvarnished view of financial resilience.
| Liquidity Metric | Balance Sheet Formula | Assets Included in Numerator | Conservatism Level |
|---|---|---|---|
| Cash Ratio | (Cash & Equivalents + Marketable Securities) / Current Liabilities | Cash, bank deposits, Treasury bills, money market funds | Ultra-Strict (Zero operational assumptions) |
| Quick Ratio (Acid-Test) | (Cash + Marketable Securities + Receivables) / Current Liabilities | Cash assets plus trade accounts receivable | Moderate (Assumes customer invoices are paid on time) |
| Current Ratio | Total Current Assets / Total Current Liabilities | Cash, receivables, inventory, prepaid expenses, supplies | Broad (Assumes physical inventory can be fully sold at book value) |
