Liquidity Ratios
Liquidity and Working Capital Health
This lesson reads Current Ratio, Working Capital, Quick Ratio, and Cash Ratio together to judge short-term payment comfort and cash trapped in operations.
Concept First
Learn It Step By Step
Start with the business meaning, then move into the formula.
How should I read Current Ratio?
Current Ratio asks whether short-term assets cover short-term obligations. If Company A has current assets of Rs. 200 and current liabilities of Rs. 100, its ratio is 2.0x. Company B has current assets of Rs. 120 and current liabilities of Rs. 100, so its ratio is 1.2x. A is more comfortable on the surface. But higher is not always better: if A's Rs. 200 is mostly old inventory, while B's Rs. 120 is mostly cash and fresh receivables, B may actually be safer.
How should I read Working Capital?
Working Capital is the rupee cushion, not a percentage. If a textile trader has current assets of Rs. 500 and current liabilities of Rs. 350, working capital is Rs. 150. Positive working capital usually gives breathing room, but very high working capital can mean money is stuck in stock or customers. The better company is not the one with maximum working capital; it is the one that keeps operations smooth with minimum cash blocked.
How should I read Quick Ratio?
Quick Ratio removes inventory because inventory may take time to sell and may need discounts. Suppose two distributors both have current assets of Rs. 300 and current liabilities of Rs. 150. Company A has inventory of Rs. 60, so quick assets are Rs. 240 and Quick Ratio is 1.6x. Company B has inventory of Rs. 180, so quick assets are Rs. 120 and Quick Ratio is 0.8x. A is better placed to pay bills without depending heavily on selling stock.
How should I read Cash Ratio?
Cash Ratio is the strictest liquidity test. If current liabilities are Rs. 200 and cash is Rs. 40, Cash Ratio is 0.2x. If cash is Rs. 120, it is 0.6x. Higher cash ratio gives more immediate safety, but too much idle cash may reduce returns. A normal operating business does not need to keep every rupee of liabilities in cash if receivables collect on time and inventory moves well.
Which liquidity ratio is best?
None is best alone. Current Ratio tells broad cover. Working Capital tells the rupee cushion. Quick Ratio tests whether cover remains after excluding inventory. Cash Ratio tests immediate stress liquidity. A finance professor would read all four together and then ask: are receivables collectible, is inventory saleable, are suppliers being stretched, and is operating cash flow healthy?
Formula Lab
Understand the Formula
Read the formula like a business sentence before calculating it.
Formula 1
Current Ratio = Current Assets / Current Liabilities
Formula 2
Working Capital = Current Assets - Current Liabilities
Formula 3
Quick Ratio = (Current Assets - Inventory) / Current Liabilities
Formula 4
Cash Ratio = Cash and Cash Equivalents / Current Liabilities
Solved Case Study
Read the Numbers Like an Analyst
Work through one business case slowly: understand the situation, calculate the ratios, then interpret what the numbers are really saying.
Case context
A Pune distributor has current assets of Rs. 900L, inventory of Rs. 270L, cash of Rs. 90L, and current liabilities of Rs. 450L. Current Ratio is 2.0x, Working Capital is Rs. 450L, Quick Ratio is 1.4x, and Cash Ratio is 0.2x. The cover looks comfortable, but cash is modest and part of liquidity depends on collecting receivables and selling inventory.
Case: Two distributors with the same sales
Company A and Company B both sell Rs. 1,000L a year. A has current assets of Rs. 500L, inventory of Rs. 100L, cash of Rs. 80L, and current liabilities of Rs. 250L. B has current assets of Rs. 500L, inventory of Rs. 300L, cash of Rs. 30L, and current liabilities of Rs. 250L.
The headline current ratio is the same for both, but the quality of liquidity is different.
Calculate the broad cover
Current Ratio and Working Capital first tell us whether short-term assets cover short-term obligations.
On these two measures, both companies look equally comfortable.
Test the quality of liquidity
Now remove inventory and then look only at cash. This shows whether the company can pay bills without first selling stock.
A has stronger liquidity quality. B depends much more on selling inventory before it can comfortably pay short-term obligations.
Read the business conclusion
Higher Current Ratio is not the final answer. The professor's reading is: first check cover, then check whether the cover is cash, fresh receivables, or inventory. A is better because the same working-capital cushion is less dependent on stock conversion.
Interpretation
What This Means In Practice
Read the result as a business signal, not as a standalone number.
Liquidity is about usable cash, not just a ratio
Liquidity analysis starts with a simple question: can the company meet near-term obligations without distress? Current Ratio gives broad cover, Working Capital gives the rupee cushion, Quick Ratio removes inventory because it may not become cash quickly, and Cash Ratio is the strictest stress test. The ratios should be read together, not mechanically. A comfortable number is useful only if receivables are collectible, inventory can move, and cash is available before liabilities fall due.
What to check next
Management uses it to plan working capital, vendor payments, bank limits, and cash buffers for the operating cycle. Read this with debtor days, inventory days, payable pressure, and operating cash flow. A strong liquidity ratio with poor cash conversion is not truly comfortable.
Key Takeaway
Good liquidity is not the highest current ratio. It is enough short-term cover, good asset quality, timely collections, saleable inventory, and no hidden pressure in payables or statutory dues.
