Short-term solvency, or liquidity, is the ability to meet obligations due in the near term without unacceptable disruption or financing cost. Current and quick ratios are useful starting points, but they must be combined with cash-flow timing, working-capital quality and access to finance.
A profitable business can still fail through poor liquidity.
Core liquidity measures
| Measure | Formula | What it indicates |
|---|---|---|
| Current ratio | Current assets ÷ Current liabilities | Broad short-term asset cover |
| Quick ratio | (Current assets − Inventory) ÷ Current liabilities | Cover without relying on inventory |
| Operating cash flow ratio | Operating cash flow ÷ Average current liabilities | Cash generated relative to obligations |
| Cash ratio | Cash and cash equivalents ÷ Current liabilities | Immediate liquid cover |
| Cash conversion cycle | Inventory days + Receivables days − Payables days | Time operating cash is tied up |
Current ratio
The current ratio compares assets expected to become cash within the operating cycle or one year with liabilities due in the near term.
A high ratio is not automatically strong because inventory may be obsolete and receivables overdue.
See the current ratio guide.
Quick ratio
The quick ratio removes inventory from current assets. It is useful where inventory is slow-moving or uncertain, but still depends on receivable collectability.
Review the quick ratio guide.
Worked ratio example
Current assets are cash 80,000 CU, receivables 220,000 CU and inventory 300,000 CU. Current liabilities are 400,000 CU.
- Current ratio: 600,000 ÷ 400,000 = 1.5
- Quick ratio: 300,000 ÷ 400,000 = 0.75
The company appears dependent on inventory conversion to meet short-term obligations.
Operating cycle
Liquidity depends on when inventory is bought, sold and collected, and when suppliers are paid. Ratios measured at one date can miss seasonal peaks and daily cash pressure.
Inventory quality
Analyse inventory ageing, turnover, damage and net realisable value. High inventory can improve the current ratio while weakening actual liquidity.
Use the inventory turnover days guide.
Receivables quality
Review ageing, disputes, concentrations, expected credit losses and post-year-end collections. Revenue growth funded by slow receivables can create cash strain.
See the receivables collection period guide.
Payables and supplier finance
Longer payment periods can preserve cash but may signal distress, lose discounts or damage supply. Identify overdue balances, payment plans and supplier-finance arrangements.
Compare with the payables turnover guide.
Cash conversion cycle
The cash conversion cycle combines inventory, receivable and payable days. A shorter cycle usually reduces funding need, but extremely low inventory can increase stock-out risk.
Review the cash conversion cycle guide.
Current liability composition
Tax, payroll, trade payables, short-term debt, lease liabilities and provisions have different timing and flexibility. A single current-liability total can hide concentrated maturities.
Cash forecasts
A rolling cash forecast is often more useful than a static ratio. Forecast receipts, payroll, taxes, debt service, capital expenditure and downside scenarios by week or month.
Bank facilities
Undrawn committed facilities can support liquidity, but review expiry, covenants, collateral, interest and conditions. Uncommitted overdrafts may be withdrawn and should not be treated as guaranteed funding.
Overtrading
Rapid growth can consume cash through inventory, receivables and staffing before collections occur. Signs include rising sales with falling liquidity, maximum borrowing and delayed supplier payments.
Seasonality and window dressing
Year-end ratios can be improved temporarily by delaying purchases, collecting receivables aggressively or repaying balances just before reporting. Use monthly averages and post-year-end evidence.
Going concern connection
Liquidity analysis supports going-concern assessment, but going concern considers a broader period, financing plans, forecasts, covenants and uncertainties.
Stress testing
Test delayed customer collections, lower sales, supplier term reductions, higher interest rates and loss of facilities. Measure the earliest cash shortfall and available management actions.
Restricted and trapped cash
Cash may be restricted by law, contracts, foreign-exchange controls or operational needs. Do not treat every cash balance as freely available for current liabilities.
Supplier finance arrangements
Extended payment programmes can affect liability classification, cash-flow presentation and liquidity interpretation. Review terms, concentration and whether the arrangement changes the nature of trade payables.
Improving liquidity
- strengthen credit approval and collection;
- reduce obsolete and excess inventory;
- align purchasing with realistic demand;
- negotiate sustainable supplier terms;
- refinance short-term debt appropriately;
- sell genuinely surplus assets;
- maintain forecast and covenant headroom.
Ratio interpretation
Acceptable liquidity varies by sector. Retailers can operate with low quick ratios because sales are mainly cash, while project businesses may need larger buffers.
Use the financial ratio analysis guide for integrated interpretation.
Liquidity controls checklist
- daily cash visibility and bank reconciliation;
- aged receivable and payable review;
- inventory ageing and count controls;
- weekly or monthly cash forecasts;
- facility and covenant monitoring;
- approval of major payments and commitments;
- stress testing of delayed collections and sales decline.
Common mistakes
- assuming a ratio above 1 is automatically safe;
- ignoring obsolete inventory and doubtful receivables;
- using a year-end balance for a seasonal business;
- treating uncommitted facilities as guaranteed cash;
- improving ratios by delaying essential payments;
- analysing profit without cash-flow timing;
- applying one benchmark to every industry.
Key takeaway
Short-term solvency depends on cash timing and working-capital quality, not one ratio. Combine current and quick ratios with turnover, forecasts, facilities, covenants and operational context.
