Cash Ratio Calculator
The cash ratio is the most conservative measure of a company's short-term liquidity. Unlike the current ratio or quick ratio, it considers only cash and cash equivalents (not inventory, receivables, or other current assets) as available to meet current liabilities. A high cash ratio provides a safety margin in stressed conditions; a very low ratio may mean the business relies on collecting receivables or selling inventory before it can meet obligations. Lenders, creditors, and investors use this ratio to assess downside liquidity risk.
Cash ratio formula
Cash Ratio = (Cash + Cash Equivalents) / Current Liabilities
Example: Cash $80,000 + Equivalents $20,000 = $100,000. Current Liabilities $100,000. Cash Ratio = $100,000 / $100,000 = 1.00.
Interpreting the cash ratio
- A ratio above 1.0: the business can cover all current liabilities with cash alone.
- A ratio of 0.5 to 1.0: adequate for most businesses, supplemented by receivable collections.
- A ratio below 0.2: the business must rely heavily on converting other assets or drawing on credit lines to pay bills.
- The ideal ratio depends on industry cash flow predictability. Service businesses with fast receivables collection can operate at lower ratios than manufacturers with long inventory cycles.
Frequently asked questions
What is the cash ratio?
The cash ratio is (Cash + Cash Equivalents) / Current Liabilities. It measures the ability to pay current liabilities using only cash and near-cash assets, without converting any other assets. It is the strictest of the three liquidity ratios.
What is the difference between current ratio, quick ratio, and cash ratio?
The current ratio includes all current assets. The quick ratio excludes inventory. The cash ratio includes only cash and cash equivalents. Each is progressively more conservative. The cash ratio is most relevant for extreme stress scenarios.
What is a good cash ratio?
A cash ratio above 1.0 means the business could pay all current liabilities immediately in cash. Most healthy businesses maintain a ratio between 0.5 and 1.0. Too high a ratio may signal underutilised cash that could be invested.
What counts as cash equivalents?
Cash equivalents are highly liquid investments with original maturities of three months or less: treasury bills, money market funds, and short-term commercial paper. They are distinguished from investments with longer maturities.
When is the cash ratio most useful?
The cash ratio is most useful in credit analysis, distress assessment, and during economic uncertainty. Lenders may use it to evaluate whether a business can weather a sudden loss of revenue without accessing credit lines.
