What is liquidity?

Definition
Liquidity is how quickly and easily a business can turn its assets into cash, and so how readily it can pay its debts when they fall due. Money in the bank is the most liquid asset. Amounts customers owe and stock take longer to become cash, and equipment or property usually takes longer still.
Liquidity is about timing rather than size. A business can own plenty and still be unable to pay a supplier this week if most of what it owns is stock on the shelves, invoices customers have not paid or equipment it needs to keep trading.
Working capital and liquidity are related but not the same. Working capital is current assets minus current liabilities, a single amount. Liquidity looks at what those current assets are made of. In the table below, both businesses have the same working capital, but business A could meet its current liabilities from cash and customer payments without selling any stock, and business B could not.
A common check is to compare current assets with current liabilities, then make the same comparison again with stock left out, because stock is usually the slowest current asset to turn into cash. Looking at when each debt is due, not just the totals, gives a clearer picture still.
In Australia
business.gov.au's glossary defines liquidity as how quickly you can convert assets into cash. Its balance sheet guidance describes business liquidity in terms of how quickly you could pay your current debts, and says a balance sheet can help you work it out.
Its guide to the warning signs of financial trouble says a business that is always short of the cash it needs may be under financial strain, and suggests selling old or surplus stock, or collecting what customers owe, when debts are mounting. Its cash flow guide adds that difficulty paying bills, leaning on credit and paying suppliers late can all be signs of pressure on cash flow.
Worked example
| Item | Business A (AUD) | Business B (AUD) |
|---|---|---|
| Cash at bank | 9,000.00 | 1,500.00 |
| Accounts receivable | 3,000.00 | 3,500.00 |
| Inventory | 2,000.00 | 9,000.00 |
| Total current assets | 14,000.00 | 14,000.00 |
| Total current liabilities | 8,000.00 | 8,000.00 |
| Working capital | 6,000.00 | 6,000.00 |

Common mistakes
- Confusing liquidity with liquidation, which is the process of winding up a company.
- Counting stock as if it could be turned into cash straight away.
- Looking at balance sheet totals without checking when each bill actually falls due.
- Treating an unused overdraft limit as cash the business already holds.
