What is a good working capital ratio for a small UK business?

A ratio (current assets divided by current liabilities) above 1 generally means you can cover short-term obligations from short-term assets. Above 1.5–2 is often considered comfortable, though the right level varies by sector — a cash-heavy retailer and a project-based consultancy carry very different working capital needs.

Does a short-term business loan count as working capital?

Yes — short-term borrowing used to fund day-to-day operations (stock, a specific bill, bridging a payment gap) is a working capital tool. It is best used for a defined, temporary gap rather than as a permanent substitute for a shorter operating cycle.

How is this different from a general cashflow guide?

Cashflow management is about the timing of money in and out day to day; working capital is the underlying structural amount of cash your operating cycle needs at any given moment. The two are closely related, but working capital is the deeper, more structural number — it is what your cashflow forecast is ultimately trying to fund.

Working capital explained — what it is and how to manage it

Working capital is current assets minus current liabilities — broadly, the cash and near-cash resources a business has to cover what it owes in the near term. It sounds abstract until you see it in practice: money tied up in stock, money owed by customers, and money owed to suppliers, all moving on different timelines.

What the working capital cycle actually measures

The working capital cycle is the time between paying out cash (for stock, materials or labour) and collecting cash back in (when a customer pays). The longer that cycle, the more cash a business needs tied up to keep operating — and the more exposed it is to a single late payment or slow month.

A simple way to calculate it

Add your average days of stock held to your average debtor days (how long customers take to pay), then subtract your average creditor days (how long you take to pay suppliers). The result is roughly how many days of cash your operating cycle needs funded at any one time. Shortening any one of those three numbers reduces the cash your business has to carry.

Why growth can make working capital pressure worse, not better

A growing business often needs more stock and extends more credit to more customers before the extra sales convert to cash — so rapid, profitable growth can actually tighten cashflow in the short term, not ease it. This is one of the most counter-intuitive traps for an otherwise successful small business.

Levers you actually control

Negotiate longer supplier terms where you can. Tighten customer payment terms and chase overdue invoices consistently. Hold less stock, or negotiate smaller, more frequent deliveries. Each of these shortens the cycle without needing to borrow. Where the cycle cannot be shortened further, short-term finance can fund the remaining gap directly.
