Quick ratio (acid test)

The quick ratio, or acid test, is a stricter version of the current ratio that strips out stock — showing whether a company could pay its short-term bills without having to sell inventory first.

Definition

The quick ratio (acid-test ratio) is current assets minus stock, divided by current liabilities. By excluding inventory — which can be slow to turn into cash — it gives a tougher read on immediate liquidity than the current ratio.

In plain terms

It answers a sharper question: could you pay this year's bills right now, without relying on selling stock? For stock-heavy businesses that's a very different number.

Why it matters for your company

It's especially telling for retailers and manufacturers holding lots of inventory. Read it alongside cash forecasts. See working capital management.
