Cash Ratio

What is the cash ratio?

The cash ratio measures whether a business could pay its current liabilities using only cash and cash equivalents. It is the strictest of the common liquidity ratios because it leaves out receivables, inventory, and prepaid expenses. A ratio of 1.0 means cash on hand covers every bill due within a year.

How to calculate the cash ratio

Cash ratio = (cash + cash equivalents) ÷ current liabilities

Cash equivalents are short-term, highly liquid holdings such as money market funds. Current liabilities are obligations due within one year, such as accounts payable, accrued payroll, credit card balances, and the current portion of debt.

Worked example

The figures below are illustrative. A firm holds $80,000 in its operating account and $20,000 in a money market fund. Its current liabilities are $60,000 in accounts payable, $35,000 in accrued payroll, $15,000 in credit card balances, and $15,000 in the current portion of a loan.

• Cash and equivalents: $80,000 plus $20,000 equals $100,000
• Current liabilities: $60,000 plus $35,000 plus $15,000 plus $15,000 equals $125,000
• Cash ratio: $100,000 ÷ $125,000 equals 0.8

How to read the result

At 1.0 or above, cash alone covers every current liability. Many healthy operating businesses run below 1.0 because customer payments arrive during the year, so a result of 0.8 is not automatically a warning sign. A very high ratio can mean cash is sitting idle when it could be invested in the business. Trend and context matter more than any single number.

How it compares with related ratios

• The quick ratio adds receivables and short-term investments to cash
• The current ratio counts all current assets, including inventory and prepaid expenses
• The cash ratio uses cash alone, which makes it the most conservative of the three

Lenders, boards, and funders often look at these ratios together. For forward-looking planning, pair the ratio with cash runway and our guide to the cash runway calculator for service firms.

Frequently asked questions

Is a cash ratio below 1.0 a problem?

Not by itself. Most operating businesses collect receivables during the year, so cash on hand rarely covers every current liability at once. It becomes a concern when the ratio is falling, when large bills are due before cash arrives, or when the firm has little access to credit. Check it together with the quick ratio and upcoming cash needs.

How is the cash ratio different from the quick ratio?

The quick ratio includes cash, short-term investments, and accounts receivable, so it assumes customers will pay on time. The cash ratio counts only cash and cash equivalents. The cash ratio is the stricter test, while the quick ratio gives a more realistic picture for firms with reliable collections.
