Liquidity Ratios: Current, Quick and Cash
5 minutes
5 Questions
Liquidity ratios are core tools in the Certified Treasury Professional (CTP) body of knowledge for assessing a company's ability to meet short-term obligations as they come due. Treasury professionals use them to evaluate corporate liquidity, communicate with lenders and rating agencies, and monitor covenant compliance. The three principal ratios are the Current Ratio, the Quick Ratio, and the Cash Ratio, each applying a progressively stricter definition of liquid resources. 1. Current Ratio = Current Assets / Current Liabilities. This is the broadest measure, including cash, marketable securities, accounts receivable, inventory, and prepaid expenses. A ratio above 1.0 suggests the firm has more short-term assets than short-term obligations. However, it can overstate liquidity because inventory and prepaid items may not be quickly or fully convertible to cash. Industry norms vary widely; a manufacturer may require a higher ratio than a retailer with rapid cash turnover. 2. Quick Ratio (Acid-Test Ratio) = (Cash + Marketable Securities + Accounts Receivable) / Current Liabilities, or equivalently (Current Assets − Inventory − Prepaids) / Current Liabilities. By excluding inventory and prepaid expenses, it focuses on assets that can be converted to cash within roughly 90 days. It is a more conservative indicator and is particularly useful when inventory is slow-moving, obsolete, or difficult to liquidate. 3. Cash Ratio = (Cash + Marketable Securities) / Current Liabilities. This is the most stringent test, counting only cash and cash equivalents. It shows whether a firm could immediately pay all current liabilities without collecting receivables or selling inventory. A very low cash ratio may signal dependence on credit lines, while an excessively high ratio may indicate idle cash that could be invested or returned to shareholders. For the CTP, remember that these ratios are static balance-sheet snapshots. Treasury professionals supplement them with cash flow forecasting, working capital metrics (DSO, DIO, DPO), and analysis of available credit facilities to form a complete picture of liquidity and financial flexibility.

1. Why This Topic Matters
Liquidity is the lifeblood of treasury. A company can be profitable on paper and still fail because it cannot pay its obligations when they come due. The Certified Treasury Professional (CTP) exam places liquidity ratios inside the Corporate Liquidity Management domain because the treasurer is the executive ultimately responsible for ensuring the firm can meet short-term obligations. Liquidity ratios are the quickest, most widely understood way to measure that ability.
In practice, treasury professionals use these ratios to:
• Monitor the firm's own short-term financial health and report it to senior management and the board.
• Comply with loan covenants — banks frequently require a minimum current ratio or quick ratio, and a breach can trigger default.
• Evaluate counterparties such as customers (for credit limits), suppliers (for supply-chain risk) and banks or investment issuers.
• Support credit rating discussions and investor communications.
• Benchmark against industry peers and detect deteriorating trends before they become crises.
On the CTP exam, this is a high-yield topic: it is testable through direct calculation, through interpretation, and through transaction-effect questions (how does a given action change the ratio?). It also connects to working capital, the cash conversion cycle, short-term investing and short-term borrowing, so mastering it strengthens several other areas.
2. What Liquidity Ratios Are
Liquidity ratios compare a company's liquid resources (assets expected to convert to cash within one year or one operating cycle) to its current liabilities (obligations due within the same period). They are balance sheet ratios — snapshots at a point in time — and they answer the question: If all short-term obligations came due, how many dollars of near-cash resources exist for each dollar owed?
The three ratios form a hierarchy, moving from the broadest to the most conservative definition of liquid assets:
A. Current Ratio (Working Capital Ratio)
Current Ratio = Current Assets ÷ Current Liabilities
Current assets typically include cash, marketable securities (short-term investments), accounts receivable, inventory and prepaid expenses. Current liabilities include accounts payable, accrued expenses, short-term debt (notes payable, commercial paper, lines of credit), the current portion of long-term debt, taxes payable and other obligations due within a year.
Closely related: Net Working Capital = Current Assets − Current Liabilities. A current ratio above 1.0 means positive net working capital; below 1.0 means negative net working capital.
B. Quick Ratio (Acid-Test Ratio)
Quick Ratio = (Cash + Marketable Securities + Accounts Receivable) ÷ Current Liabilities
Equivalently: (Current Assets − Inventory − Prepaid Expenses) ÷ Current Liabilities
The quick ratio removes inventory (because it may be slow to sell, may sell below book value, or may be obsolete) and prepaid expenses (because they can never be converted to cash — they are consumed, not collected). It focuses on assets that can be converted to cash quickly without a sale of goods having to occur first. Some textbooks define the quick ratio simply as current assets minus inventory; if an exam question gives you prepaid expenses as a separate line, the safest CTP approach is to exclude them as well, because the AFP's Essentials of Treasury Management defines quick assets as cash, short-term investments and receivables.
C. Cash Ratio
Cash Ratio = (Cash + Marketable Securities) ÷ Current Liabilities
The cash ratio is the most conservative measure. It removes receivables as well, because collecting receivables depends on customers paying on time. It asks: Could the company pay its current liabilities today using only cash and near-cash investments? Cash ratios well below 1.0 are normal; a ratio near or above 1.0 is unusual and may actually signal idle cash that could be deployed more productively.
3. How the Ratios Work — Worked Example
Suppose a company has the following balance sheet data (in millions):
• Cash: $200
• Marketable securities: $100
• Accounts receivable: $300
• Inventory: $400
• Prepaid expenses: $50
• Total current assets: $1,050
• Accounts payable: $250
• Accrued expenses: $100
• Short-term notes payable: $150
• Total current liabilities: $500
Current Ratio = 1,050 ÷ 500 = 2.10
Quick Ratio = (200 + 100 + 300) ÷ 500 = 600 ÷ 500 = 1.20
Cash Ratio = (200 + 100) ÷ 500 = 300 ÷ 500 = 0.60
Interpretation: For every $1 of short-term obligations the firm has $2.10 of current assets, $1.20 of quick assets, and $0.60 of cash and equivalents. The large gap between the current ratio and the quick ratio ($450 of inventory and prepaids) tells an analyst the firm is inventory-heavy — its liquidity depends significantly on selling goods. Notice the ratios always descend: Current ≥ Quick ≥ Cash. If your answer violates that order, you have made an error.
Interpreting the Numbers
• Higher is safer, but not always better. A very high current ratio can indicate excess inventory, slow collections or cash sitting idle — all signs of inefficient asset use that lower return on assets. Treasury's goal is adequate liquidity, not maximum liquidity.
• Lower is riskier, but not always bad. Firms with fast, predictable cash inflows (grocery chains, restaurants, utilities, subscription businesses) can safely operate with current ratios below 1.0 because they collect cash from customers before they pay suppliers. Capital-intensive manufacturers with long production cycles usually need higher ratios.
• Industry benchmarks and trends matter more than absolute rules of thumb. The old guideline of a 2.0 current ratio and 1.0 quick ratio is a starting point, not a standard. Compare to peers and to the company's own history.
• Covenants define the binding constraint. If a credit agreement requires a current ratio of at least 1.25, then 1.25 is the number treasury watches, regardless of textbook norms.
Transaction Effects — The Most Tested Logic
Many exam items ask how a specific transaction changes a ratio. Use this reasoning framework:
Rule 1 — Equal change to numerator and denominator: If a ratio is above 1.0 and you subtract the same amount from both numerator and denominator, the ratio increases. If the ratio is below 1.0, the same action decreases it. Adding the same amount to both does the opposite.
Rule 2 — Reclassification within the numerator: Swapping one current asset for another of equal value leaves the current ratio unchanged but may change the quick or cash ratio.
Examples (assume current ratio starts above 1.0):
• Pay accounts payable with cash: Cash down, AP down equally. Current ratio and quick ratio increase; cash ratio also increases if above 1.0 and decreases if below 1.0 (usually decreases).
• Collect accounts receivable: Cash up, AR down. Current ratio unchanged, quick ratio unchanged, cash ratio increases.
• Buy inventory with cash: Cash down, inventory up. Current ratio unchanged, quick ratio decreases, cash ratio decreases.
• Buy inventory on credit: Inventory up, AP up. Current ratio decreases (if above 1.0); quick ratio and cash ratio decrease because only the denominator grew.
• Borrow long-term debt and hold the cash: Cash up, no change to current liabilities. All three ratios increase.
• Draw on a short-term line of credit and hold the cash: Cash up, short-term debt up equally. Current ratio decreases (if above 1.0), quick ratio decreases (if above 1.0), cash ratio moves toward 1.0.
• Long-term debt becomes due within 12 months: It reclassifies to the current portion of long-term debt. All three ratios decrease because current liabilities rise with no change in current assets.
• Sell inventory for cash at a profit: Inventory out at cost, cash in at a higher amount. Current ratio increases, quick and cash ratios increase.
• Write off obsolete inventory: Current ratio decreases; quick and cash ratios unchanged.
• Declare a cash dividend (not yet paid): Dividends payable (a current liability) increases. All three ratios decrease.
• Purchase equipment with cash: Cash becomes a fixed asset. All three ratios decrease.
Limitations Treasury Professionals Must Recognize
• Point-in-time snapshot: The balance sheet date may not represent typical conditions, especially for seasonal businesses.
• Window dressing: Management can temporarily improve ratios at period-end — paying down payables just before the date, delaying purchases, or accelerating collections. The treasurer should look at averages and intra-period data.
• Quality of assets ignored: Receivables from a weak customer and slow-moving inventory count at full book value.
• Static vs. dynamic liquidity: Ratios do not capture unused committed credit facilities, the ability to issue commercial paper, or expected operating cash flows. That is why treasury supplements ratios with the cash conversion cycle, cash flow forecasts, operating cash flow ratio and measures of available liquidity (cash plus undrawn committed lines).
• Accounting policy differences: Inventory valuation methods (FIFO, LIFO, weighted average) and receivable allowance policies alter the numbers and make cross-company comparisons imperfect.
Relationship to Other CTP Concepts
• Working capital management: Reducing days sales outstanding or days inventory outstanding frees cash and raises the quick and cash ratios.
• Cash conversion cycle (CCC): A shorter CCC generally means a firm can operate safely with lower liquidity ratios.
• Short-term investing: Marketable securities count as quick and cash assets only if they are truly short-term and liquid; treasury's investment policy affects reported liquidity.
• Short-term borrowing and covenants: Ratio covenants shape financing choices — for instance, borrowing long-term rather than short-term to protect the current ratio.
• Credit analysis: When extending trade credit, treasury or credit departments apply these same ratios to customers.
4. How to Answer Exam Questions on This Topic
Step 1 — Identify which ratio is being asked. Watch for synonyms: working capital ratio = current ratio; acid-test = quick ratio.
Step 2 — Classify every item given. Sort each balance into: cash and marketable securities, receivables, inventory, prepaids, other current assets, current liabilities, or non-current (ignore). Common traps: the current portion of long-term debt is a current liability; long-term debt, property, plant and equipment, goodwill and intangible assets are not current; restricted cash may need to be excluded if the question says so.
Step 3 — Apply the formula and check the hierarchy. Current ≥ Quick ≥ Cash, always. If your quick ratio exceeds your current ratio, you have misclassified something.
Step 4 — For transaction questions, write the before-and-after. Jot the numerator and denominator before the transaction, adjust each, and recompute. Then apply Rule 1 (equal change) or Rule 2 (reclassification) to confirm the direction.
Step 5 — For interpretation questions, think like a treasurer, not an accountant. The exam often rewards the answer that recognizes nuance: a higher ratio is not automatically better, industry context matters, and off-balance-sheet liquidity (credit lines) is not captured in the ratios.
Sample Question 1: A company has current assets of $800,000, including inventory of $300,000 and prepaid expenses of $20,000. Current liabilities are $400,000. What is the quick ratio?
Solution: Quick assets = 800,000 − 300,000 − 20,000 = 480,000. Quick ratio = 480,000 ÷ 400,000 = 1.20. (If the answer choices include 1.25, that is the trap for forgetting prepaids; if they include 2.00, that is the trap for computing the current ratio.)
Sample Question 2: A firm with a current ratio of 1.8 uses $50,000 of cash to pay down accounts payable. What happens to the current ratio and the quick ratio?
Solution: Numerator and denominator both fall by $50,000 and the ratio is above 1.0, so both the current ratio and the quick ratio increase.
Sample Question 3: Which action would improve a company's cash ratio but leave its quick ratio unchanged?
Solution: Collecting accounts receivable. Cash rises, receivables fall; quick assets are unchanged, but cash and equivalents increase.
Sample Question 4: A treasurer notes that the company's current ratio has risen from 1.5 to 3.0 over two years while sales have been flat. What is the most likely concern?
Solution: The firm may be accumulating slow-moving inventory, slow-paying receivables or idle cash — a sign of inefficient use of current assets rather than improved health. The best answer will not simply say liquidity has improved.
5. Exam Tips: Answering Questions on Liquidity Ratios: Current, Quick and Cash
1. Memorize the three formulas as a ladder. Current ratio uses everything current; quick ratio drops inventory and prepaids; cash ratio drops receivables too. Visualizing the ladder prevents mixing them up under time pressure.
2. Prepaid expenses are never quick assets. They cannot be converted to cash. If the problem lists them, exclude them from quick and cash ratios. Only if the question explicitly defines the quick ratio as current assets minus inventory should you leave them in.
3. Marketable securities count as cash equivalents. Short-term investments, treasury bills and money market funds belong in the numerator of all three ratios.
4. Watch the current portion of long-term debt. It is a classic distractor. It belongs in current liabilities. Conversely, do not include the long-term portion.
5. Use the above-1.0 / below-1.0 rule for transaction questions. When the same amount is removed from both top and bottom, a ratio above 1.0 rises and a ratio below 1.0 falls. Adding the same amount to both does the reverse. This single rule solves most transaction-effect items in seconds.
6. Reclassifications inside current assets do not move the current ratio. Collecting receivables or buying inventory with cash leaves the current ratio flat but shifts the quick and cash ratios. Expect at least one question built on this distinction.
7. Check the ordering of your answers. If the question asks for all three ratios, confirm Current ≥ Quick ≥ Cash. A violation means a classification error.
8. Do not assume higher is better. The CTP exam frequently tests the idea that excess liquidity signals poor asset utilization and lower returns. The treasurer's objective is optimal, not maximum, liquidity.
9. Think about industry when interpreting. Retailers, restaurants and utilities commonly run low ratios; manufacturers, distributors and project-based firms run higher ones. An answer that applies a universal 2.0 benchmark is usually wrong.
10. Remember what ratios miss. Undrawn committed credit facilities, commercial paper capacity and forecast operating cash flows are real liquidity sources that do not appear in the ratios. Questions about the limitations of liquidity ratios want you to mention these, along with window dressing and the point-in-time nature of the balance sheet.
11. Link to covenants. If a scenario mentions a loan agreement, the ratio threshold in the covenant becomes the key number. Consider how a proposed financing (short-term vs. long-term borrowing) affects compliance.
12. Show your arithmetic on scratch paper. Write numerator, denominator and result for each ratio. Most calculation errors come from adding the wrong items, not from division. Round only at the final step.
13. Read for the word 'most' or 'best'. Interpretation questions often have several partially correct choices; the credited answer is the one that reflects treasury judgment — adequate liquidity, efficient asset use, and awareness of ratio limitations.
Summary
The current, quick and cash ratios measure a company's ability to meet short-term obligations with progressively stricter definitions of liquid assets. For the CTP candidate, success depends on precise classification of balance sheet items, fluency with the three formulas, mastery of the transaction-effect logic, and the judgment to interpret results in context — recognizing that too much liquidity is a cost, too little is a risk, and the ratios themselves are only one piece of a complete liquidity management picture.
