Quick Ratio Calculator
Liquidity Without Relying on a Fire Sale of Inventory
The current ratio treats inventory as if it can be turned into cash on short notice, which isn't always realistic — unsold stock can sit for months, and liquidating it quickly usually means selling at a discount. The quick ratio, sometimes called the acid-test ratio, removes inventory (and prepaid expenses, which can't be converted to cash at all) from the equation, leaving only the assets that can genuinely be used to pay a bill due tomorrow.
The Formula
This calculator supports two equivalent ways to reach the same figure, depending on which numbers are on hand:
From Current Assets:
Quick Ratio = (Current Assets − Inventory − Prepaid Expenses) / Current Liabilities
From Components:
Quick Ratio = (Cash + Marketable Securities + Accounts Receivable) / Current Liabilities
Quick Ratio = (Current Assets − Inventory − Prepaid Expenses) / Current Liabilities
From Components:
Quick Ratio = (Cash + Marketable Securities + Accounts Receivable) / Current Liabilities
A Worked Example
| Item | Amount |
|---|---|
| Current Assets | $250,000 |
| − Inventory | $80,000 |
| − Prepaid Expenses | $10,000 |
| Quick Assets | $160,000 |
| Current Liabilities | $140,000 |
| Quick Ratio | 1.14 |
Where This Calculation Matters
- Retail and manufacturing review — businesses holding large inventory balances often look healthy on the current ratio but far less so on the quick ratio, which is exactly the gap this metric is built to expose.
- Short-notice obligations — when a liability is due within days rather than months, quick assets are the realistic pool of funds available, not the full current asset base.
- Credit risk screening — lenders extending short-term facilities often prefer the quick ratio over the current ratio precisely because it excludes assets that are slow or uncertain to convert to cash.
- Cross-checking the current ratio — a current ratio that looks strong but a quick ratio well below 1.0 usually means too much value is parked in inventory.
