Quick Ratio and Current Ratio

The two ratios

Current Ratio = Current Assets / Current Liabilities. Above 1.0 means short-term assets cover short-term obligations on paper. Lenders typically want to see 1.5-2.0 for comfort.

Quick Ratio (Acid-Test) = (Current Assets − Inventory) / Current Liabilities. By stripping inventory, it asks whether you could meet obligations without selling stock. Useful for inventory-heavy businesses where 'current assets' overstates real liquidity. Above 1.0 is healthy.

Limits of these ratios

Both ratios are static snapshots from the balance sheet. They don't capture timing — \$100K of receivables due in 60 days isn't the same as \$100K in the bank. For genuine short-term liquidity, the 13-week cash forecast is more useful than either ratio.

However, lenders almost always include current and quick ratio covenants in business loans. Falling below the covenant (typically Quick > 1.0 or Current > 1.5) can technically default the loan even if cash flow is fine. Track them monthly so you don't trip a covenant by accident.

What the ratios miss

Both ratios assume current assets convert to cash within a year, which is broadly true but hides a lot. Inventory in the current ratio might be obsolete; receivables might be aging into bad debt; prepaid expenses are not cash convertible at all. The quick ratio (current assets minus inventory divided by current liabilities) is more conservative but still doesn't filter for AR quality.

A useful refinement is the cash ratio: (cash + short-term marketable securities) ÷ current liabilities. This tells you what you could pay today without collecting another dollar from anyone. A cash ratio below 0.2 means the business is one missed collection cycle from a liquidity event; above 0.5 means you may be over-reserving cash that could be put to work.

Lender covenants commonly include a current ratio minimum of 1.25 or 1.5 and may also require a quick ratio of 1.0 or higher. Watch the trend more than the level — a current ratio that's been falling for four quarters is a more meaningful signal than a single low reading caused by a one-time event.

Trend matters more than the snapshot. Compute the ratios monthly for at least 24 months and look at the slope. A current ratio that's drifted from 2.0 to 1.3 over two years signals the same thing whether you cross the lender threshold or not — the business is becoming progressively less liquid, and the cause needs to be identified before the trend forces a covenant amendment.
