What is liquidity?
Liquidity is a business's ability to pay its short-term bills on time, using cash or assets that can quickly be turned into cash.
What liquidity means
Liquidity describes how quickly and easily a business can meet the payments it owes in the next few months: suppliers, wages, VAT, rent and loan repayments. Cash in the bank is the most liquid asset there is. Money owed by customers is close behind, because it should arrive within weeks. Stock is less liquid, since it has to be sold first, and equipment or property is the least liquid of all.
A business can be profitable and still run short of liquidity. Profit is measured over a year; liquidity is about whether the cash is there on the day a bill is due.
How to measure it
Two ratios are used most often, both taken from the balance sheet:
- Current ratio: current assets divided by current liabilities. Above 1 means short-term assets cover short-term debts.
- Quick ratio: current assets less stock, divided by current liabilities. It is a stricter test because stock may take time to sell.
Example
A London homeware shop has £8,000 in the bank, £4,000 owed by trade customers and £18,000 of stock. It owes £12,000 to suppliers and £6,000 in VAT and PAYE, so current liabilities are £18,000.
| Measure | Calculation | Result |
|---|---|---|
| Current ratio | £30,000 ÷ £18,000 | 1.67 |
| Quick ratio | £12,000 ÷ £18,000 | 0.67 |
The current ratio looks comfortable, but the quick ratio shows the shop depends on selling stock to pay its bills. A slow month could leave it unable to pay the VAT bill on time.
Why it matters for your business
Running out of cash, not running out of profit, is what usually closes small businesses. Watching liquidity tells you early when to chase debtors, slow down stock purchases, agree longer terms with suppliers or arrange an overdraft before you need it. Lenders and landlords also look at these ratios when deciding whether to offer credit.
Keeping an eye on working capital and a rolling cash flow forecast is the practical way to manage liquidity month to month.
Liquidity vs solvency
Liquidity is short term: can you pay what is due soon? Solvency is long term: do your total assets exceed your total liabilities? A company with valuable property but no cash may be solvent yet illiquid. Directors of a company that cannot pay its debts as they fall due must put creditors' interests first, so a liquidity problem is also a legal one.
Common questions
A current ratio between about 1.2 and 2 is generally seen as healthy for a small business, and a quick ratio of 1 or more means you can pay short-term bills without selling stock. What counts as good varies by sector: a café turns stock into cash daily, while a builder may wait months.
Invoice promptly and chase overdue payments, offer card or direct debit payment, hold less stock, negotiate longer supplier terms and avoid paying for equipment from cash when finance is cheaper. A cash flow forecast shows where the pinch points will be so you can act early.
