Definition (canonical)
Liquidity is a company's ability to pay its obligations on time. A liquid business converts assets to cash fast enough to cover invoices, salaries and taxes as they fall due. Losing liquidity — not losing profitability — is the immediate trigger of most bankruptcies.
The three ratios
| Ratio | Formula | Typical safe zone |
|---|---|---|
| Current ratio | current assets ÷ current liabilities | ~1.2–2.0 |
| Quick ratio | (current assets − inventory) ÷ current liabilities | ~1.0 |
| Cash ratio | cash + equivalents ÷ current liabilities | ~0.1–0.2 |
Each strips away less-liquid assets: the current ratio trusts everything short-term, the quick ratio drops inventory (which may take months to sell), the cash ratio counts only money in hand. Read them as a set — a high current ratio with a collapsing quick ratio screams "warehouse full, bank account empty."
Benchmarks are directional, not law
Safe zones vary by model: a supermarket with daily cash sales runs safely below 1.0; a manufacturer with long production cycles needs more. Two better questions than "is my ratio textbook-correct": is the trend deteriorating quarter over quarter, and how do I compare with my industry's median? Persistent decline warns earlier than any single value — and links directly to working capital mechanics.
Improving liquidity, in order of speed
Fastest: accelerate receivables (immediate invoicing, shorter terms, factoring for instant cash). Next: trim inventory to demand. Then: renegotiate supplier terms and convert short-term debt into longer maturities. Last resort, structural: equity injection. Cost-cutting helps profit first and liquidity only later — a common sequencing mistake in a cash crunch. Track a 13-week cash flow forecast so the crunch never surprises you.
FAQ
Can a profitable company lose liquidity? Routinely — profit sits in unpaid invoices and stock while bills are due in cash. That gap is the classic path to insolvency.
How often should I check the ratios? Monthly at minimum; weekly cash forecasting in tight periods.
Is very high liquidity good? Above ~3.0 usually means idle assets earning nothing — safety bought at the price of efficiency.
What is the difference between liquidity and solvency? Liquidity is short-term: can you pay this month's bills. Solvency is structural: do total assets exceed total debts. A firm can be solvent yet illiquid (rich in assets, out of cash) — and that combination still ends in court if bills go unpaid.
