Working capital loan

A working capital loan is financing used to fund a business's day-to-day operating requirements — buying inventory, paying wages, covering supplier invoices and bridging the gap until customers pay — rather than to purchase long-term assets. It is short-term by design and is repaid from the cash that normal trading generates.

The distinction from other business borrowing is about what the money funds and where repayment comes from. A term loan buys an asset and is repaid from the profits that asset produces over years. A working capital loan funds a trading cycle and is repaid when that cycle completes: stock is sold, the invoice is issued, the customer pays.

This is why working capital finance is described as self-liquidating. The thing it funds turns back into cash on its own, and that cash repays the facility.

Working capital vs. a working capital loan

Two related but distinct terms.

Working capital is a balance sheet measure:

Working capital = current assets − current liabilities

It represents the short-term resources available to run the business. Positive working capital means current assets exceed near-term obligations.

A working capital loan is the credit product used to finance a shortfall in that position — or, more usefully, to fund the timing gap that creates the need in the first place.

The timing gap that creates the need

Most businesses pay before they get paid. A manufacturer buys raw materials, holds them, produces, sells on credit, then waits for payment. Cash goes out at the start and comes back at the end. The distance between the two is the cash conversion cycle:

Cash conversion cycle (CCC) = days inventory outstanding
                            + days sales outstanding
                            − days payables outstanding

Worked example. A manufacturer holds 60 days of inventory, collects from customers in 45 days, and pays suppliers in 35 days:

CCC = 60 + 45 − 35 = 70 days

With annual operating cash outflows of $2.4 million:

Daily outflow       = 2,400,000 ÷ 365 = $6,575
Working capital gap = 6,575 × 70 ≈ $460,000

That $460,000 is the amount of funding permanently tied up in the trading cycle at current volumes. It is the anchor for sizing a facility.

Two adjustments matter in practice:

• Seasonality. A business with a concentrated selling season may need 1.5 to 2 times the average requirement at peak, and almost nothing off-peak. Sizing to the average leaves it short exactly when it matters.
• Growth. Working capital requirement scales with turnover. A business growing 40% needs roughly 40% more funding tied up in the cycle — which is why profitable, fast-growing businesses run out of cash.

What working capital finance should and should not fund

Appropriate uses

• Inventory and raw material purchases
• Payroll and operating expenses between receipts
• The receivables gap after invoicing
• Seasonal build-up ahead of a peak trading period
• Bridging a single large order that stretches normal capacity

Inappropriate uses

• Buying fixed assets — vehicles, machinery, premises
• Repaying long-term debt
• Funding operating losses
• Distributions to owners

The underlying rule is the matching principle: short-term assets are financed with short-term liabilities, long-term assets with long-term funding. Using a 90-day facility to buy a machine with a seven-year life creates a repayment obligation years before the asset generates the cash to meet it. Most working capital distress traces back to this single error.

Forms of working capital finance

• Overdraft — Draw below zero on a current account up to a limit; interest charged on drawn balance only. Best suited to unpredictable, fluctuating short gaps.
• Revolving credit facility — Standalone committed line, drawn and repaid repeatedly. Best suited to larger or committed working capital needs.
• Short-term term loan — Fixed amount, fixed schedule, 3–24 months. Best suited to a known, one-off requirement.
• Invoice discounting / factoring — Advance against unpaid invoices, typically 70–90% of face value. Best suited to businesses with long receivable days and creditworthy customers.
• Trade finance / letters of credit — Bank instrument securing payment to a supplier. Best suited to importers and cross-border purchasing.
• Purchase order finance — Funds supplier costs against a confirmed customer order. Best suited to order-driven businesses without stock cover.
• Supplier / trade credit — Extended payment terms from suppliers. Best suited to reducing the gap at source, often at no explicit cost.
• Merchant cash advance — Advance repaid as a share of card or till receipts. Best suited to retail with steady card volume, though usually expensive.

The right instrument follows the shape of the need. A fluctuating gap suits an overdraft; a predictable one suits a short term loan; a receivables-driven gap suits invoice finance, which grows automatically as sales grow.

How lenders assess a working capital request

The central question is whether the operating cycle actually converts to cash.

• Turnover and gross margin — the volume the facility supports and the cushion in the pricing
• Receivables ageing — how much is current versus 60 or 90 days overdue, since an aged book is a collection problem disguised as an asset
• Customer concentration — a single customer representing a large share of receivables makes the whole book a single credit exposure
• Inventory turns and composition — slow-moving or obsolete stock is not near-cash regardless of its book value
• Payables discipline — stretched supplier terms may indicate existing stress rather than negotiating strength
• Account conduct — turnover through the account versus declared trading, and whether existing facilities swing back into credit
• Existing facilities and security — what is already charged over the same stock and receivables

Common covenants include a minimum current ratio (current assets ÷ current liabilities, often 1.2–1.5), a quick ratio excluding inventory (often at least 1.0), and a debt service coverage ratio of around 1.2x or better.

Structure, security and pricing

Working capital facilities are typically:

• Short tenor — 3 to 24 months, or rolling with annual review
• Secured over current assets — a debenture or floating charge over stock and receivables, so the security moves with the trading cycle
• Supported by a personal guarantee from owners of smaller businesses
• Priced above term debt where unsecured or where the receivables book is weak, and below it where invoice-backed with strong debtors
• Reviewed annually, with renewal dependent on conduct and on the receivables book holding up

Invoice-backed facilities often price keenest, because the lender is effectively taking exposure to the borrower's customers rather than to the borrower.

Warning signs

Certain patterns indicate the facility is being used to hide a structural problem rather than fund a timing gap:

• A facility that never clears. A permanently drawn balance is long-term funding dressed as short-term credit. See the discussion of the hardcore overdraft.
• Rising utilisation with flat turnover. More funding supporting the same trading volume means cash is being consumed somewhere — usually losses, or a deteriorating debtor book.
• Lengthening receivables. Debtor days rising quarter on quarter means the sales are being made but the cash is not arriving.
• Stretching payables. Supplier terms extending beyond agreement is often the earliest visible symptom of a cash shortage.
• Refinancing the facility with a new facility. Rolling one working capital loan into another without the cycle ever clearing is evergreening.
