Working Capital Ratios: Current Ratio, Quick Ratio and Cash Cycle
Working Capital Ratios: Current Ratio, Quick Ratio and Cash Cycle
A business with $300,000 of current assets and $200,000 due within a year has a current ratio of 1.50, a quick ratio of 1.00 and a cash conversion cycle of 55.6 days. Lenders read those numbers before they read the income statement. Shortening collections and inventory and extending payables within terms would release about $66,000 without borrowing anything.
What you'll learn
The ratios lenders read first
Before a lender looks at profit, it often looks at liquidity: whether the business can meet the bills coming due in the next year from assets that will turn into cash in the same period. Working capital ratios answer that question in a few numbers, and they appear in loan approvals, covenants and annual reviews. Per our small business underwriting analysis, a profitable business with poor liquidity can still be declined, because profit does not pay bills that are due before customers pay.
The ratios, worked
Take a business with $1.2 million of annual revenue and $840,000 of cost of goods sold.
| Current assets | Current liabilities | ||
|---|---|---|---|
| Cash | $60,000 | Accounts payable | $70,000 |
| Accounts receivable | $140,000 | Accrued expenses | $30,000 |
| Inventory | $100,000 | Current portion of term debt | $40,000 |
| Line of credit balance | $60,000 | ||
| Total | $300,000 | Total | $200,000 |
| Measure | Formula | Result |
|---|---|---|
| Working capital | Current assets minus current liabilities | $100,000 |
| Current ratio | Current assets ÷ current liabilities | 1.50 |
| Quick ratio | (Cash + receivables) ÷ current liabilities | 1.00 |
| Days sales outstanding | Receivables ÷ revenue × 365 | 42.6 days |
| Days inventory outstanding | Inventory ÷ cost of goods sold × 365 | 43.5 days |
| Days payables outstanding | Payables ÷ cost of goods sold × 365 | 30.4 days |
| Cash conversion cycle | DSO + DIO − DPO | 55.6 days |
What lenders read into these numbers. A current ratio above about 1.2 to 1.5 is commonly expected, though norms vary widely by industry. A quick ratio near 1.0 means the business could meet its current obligations without selling inventory. The cash conversion cycle shows how many days the business funds its own operations between paying suppliers and collecting from customers. Per our timing mismatch analysis, that gap is what working capital financing exists to fill.
Where the cash is hiding
| Change | Cash released |
|---|---|
| Collect receivables in 35 days instead of 42.6 | about $25,000 |
| Hold 35 days of inventory instead of 43.5 | about $19,500 |
| Pay suppliers in 40 days instead of 30.4, within terms | about $22,000 |
Together, those changes release about $66,000 without borrowing a dollar. Per our faster payment analysis, invoicing promptly, offering easy payment methods and following up early shorten DSO. Per our supplier terms analysis, negotiating longer terms extends DPO, though paying late damages supplier relationships and business credit. Per our inventory analysis, inventory is often the largest and slowest store of trapped cash.
Why norms differ by industry
| Business type | Typical working capital pattern |
|---|---|
| Restaurants | Customers pay immediately and suppliers are paid later, so the cash cycle can be short or negative and current ratios below 1.0 are common |
| Retail | Large inventory, quick customer payment; DIO dominates |
| Distribution and wholesale | Both receivables and inventory are large; long cycles need financing |
| Construction | Progress billing and retainage tie up receivables for months |
| Subscription software and services | Little inventory; prepaid revenue can make working capital look weak while cash is strong |
Lenders compare a business with its industry, not with a universal benchmark. Per our retainage analysis, a contractor with a third of its receivables held back until project completion has a very different liquidity profile from a café with the same current ratio.
Financing the cycle
When the cash conversion cycle cannot be shortened enough, the gap is financed. The right tool depends on which part of the cycle is long.
- Long receivables: per our factoring analysis, invoice factoring or financing turns receivables into cash.
- Seasonal inventory: per our seasonal financing analysis, a line drawn before the season and repaid after it.
- Recurring gaps: per our credit structure analysis, a revolving line rather than a term loan, since the need rises and falls.
How ratios mislead
- Borrowing to buy inventory lowers the ratios. Drawing $50,000 on the line to buy inventory raises current assets to $350,000 and current liabilities to $250,000: the current ratio falls from 1.50 to 1.40 and the quick ratio from 1.00 to 0.80, even though the business may be stronger.
- Old receivables inflate liquidity. Receivables more than 90 days past due may never be collected. Per our receivables aging analysis, lenders often exclude them.
- Classification matters. A line of credit or loan maturing within a year is a current liability, so a term loan approaching maturity can push the current ratio below a covenant overnight.
- Year-end snapshots can be managed. Paying down the line on December 31 and redrawing in January flatters the ratio for one day. Lenders increasingly look at monthly averages and bank data.
Ratios as covenants
Many business loans include a minimum current ratio or minimum working capital covenant. Per our covenant analysis, a breach can let the lender raise pricing, demand additional collateral or call the loan. Per our bookkeeping analysis, accurate monthly statements let an owner see a breach coming months ahead and talk to the lender before the test date, which is when lenders have the most flexibility.
Liquidity gets you approved; credit history gets you better terms
Lenders weigh your ratios alongside your business credit file. HL Hunt Business Credit Builder reports on-time payments to business credit bureaus every month, building the record that supports larger lines and better terms as your working capital improves.
The limits of the ratios
Liquidity ratios are snapshots of the balance sheet, not forecasts of cash. A business with a strong current ratio can still run short if a large customer pays late, and one with a weak ratio may be fine if it has an undrawn line and predictable receipts. Fast-growing businesses often show weak working capital because they are investing in receivables and inventory ahead of sales. Per our cash flow forecasting analysis and growth cash analysis, a 13-week cash forecast answers the question the ratios only approximate: will there be enough cash, at each point in time, to pay what is due.
Frequently asked questions
Commonly above about 1.2 to 1.5, varying by industry.
DSO plus DIO minus DPO; 55.6 days in the example.
Collect faster, hold less inventory and extend payables within terms; about $66,000 in the example.
Yes. A $50,000 draw for inventory lowers the ratio from 1.50 to 1.40 in the example.
Key takeaways
- Working capital ratios measure whether short-term assets cover short-term obligations.
- In the example, the current ratio is 1.50 and the quick ratio 1.00.

- Shorter collections and inventory and longer payables release about $66,000 in the example.
- Borrowing for inventory, aged receivables and maturing debt can distort the ratios.
- Current ratio and working capital covenants are common in business loans.
- A 13-week cash forecast answers what the ratios only approximate.
