  • Quick Ratio (Acid-Test)

How to use

  • Enter Cash & Cash Equivalents.
  • Enter Marketable Securities.
  • Enter Accounts Receivable (net of allowances).
  • Enter Current Liabilities.
  • Press Calculate to see Quick Assets and the Quick Ratio.

Formula

Quick Ratio = (Cash and Cash Equivalents + Marketable Securities + Accounts Receivable) / Current Liabilities

Alternative form:


Quick Ratio = (Current Assets − Inventory − Prepaid Expenses) / Current Liabilities

Example

Cash = 50,000
Marketable securities = 20,000
Net receivables = 30,000
Current liabilities = 60,000

Quick assets = 50,000 + 20,000 + 30,000 = 100,000
Quick ratio = 100,000 / 60,000 = 1.67

What the result means

  • Above 1.0: more quick assets than short-term obligations.
  • Below 1.0: may need outside financing or faster collections to cover near-term bills.

Step by step guide on how to use the tool

Follow these steps to enter your balance-sheet amounts and calculate the acid-test (liquidity) ratio in CalcMastery.

  1. Enter Cash and Cash Equivalents.

    Type the total of cash on hand, bank balances, and highly liquid equivalents (e.g., T-bills under 3 months) from the balance sheet. Use plain numbers (e.g., 50000 or 50000.75). Do not include currency symbols if the field shows “$” beside it. Common mistake: adding restricted cash or long-term time deposits.

  2. Enter Marketable Securities.

    Input short-term investments that can be converted to cash quickly (e.g., money market funds, short-term bonds). Use the current balance-sheet figure for the same period as liabilities. Avoid including long-term or illiquid investments.

  3. Enter Accounts Receivable (Net).

    Use the net receivables amount after the allowance for doubtful accounts; find this on the balance sheet or notes. Enter as a number only. Common mistake: using gross receivables or including long-overdue amounts not expected to be collected.

  4. Enter Current Liabilities.

    Provide obligations due within one year: accounts payable, accrued expenses, taxes payable, and the current portion of long-term debt. Ensure the amount matches the same reporting date as your assets. Common mistake: using total liabilities instead of current liabilities.

  5. Calculate and review results.

    Click Calculate to see Quick Assets (sum of your three inputs) and the Quick Ratio. A result above 1.0 means quick assets exceed current liabilities; below 1.0 indicates potential short-term liquidity pressure. If liabilities are zero or blank, the ratio cannot be computed (division by zero).

Tip: Exclude inventory and prepaid expenses entirely—they are not part of quick assets. Enter decimals with a dot (e.g., 75.5, not 75,50).

Frequently Asked Questions

Methodology & Sources

The calculator first computes quick assets as the sum of cash and cash equivalents, marketable securities (short-term investments), and net accounts receivable, explicitly excluding inventory and prepaid expenses. It then divides quick assets by current liabilities to yield the quick (acid-test) ratio. Monetary inputs are treated as amounts in a single currency (ISO 4217 codes, if shown) but the ratio itself is unitless.

Results are rounded to two decimals using the unbiased round-half-to-even rule per NIST guidance; rounding is applied once at the end of the computation. Inputs of current liabilities equal to zero return “undefined”; negative liabilities produce a signed ratio but indicate data that should be validated.
