Current ratio
The current ratio equals current assets divided by current liabilities. If you have $80,000 of current assets and $40,000 of current liabilities, the ratio is 2.0. That means you hold two dollars of short-term assets for every dollar you owe in the near term.
A ratio above 1.0 means current assets exceed current liabilities. Below 1.0 means they do not, which can signal pressure on cash, though some businesses operate that way by design.
Quick ratio
The quick ratio is stricter. It leaves out inventory and prepaid items, because they may not turn into cash quickly. Divide cash plus receivables by current liabilities. With $40,000 of cash, $25,000 of receivables and $40,000 of current liabilities, the quick ratio is 65,000 divided by 40,000, or about 1.6.
If the quick ratio is much lower than the current ratio, inventory makes up a big part of your short-term assets. That matters if the inventory sells slowly.
What lenders look for
Lenders and credit providers sometimes set a minimum current ratio as a condition of a loan. If you have a covenant like that, track the ratio each month so you are never surprised by a breach.
The levels they expect depend on the industry and the lender. Ask which definition they use, since some include only certain accounts.
Limits of the ratios
Both ratios use balance sheet totals at one date. They do not show timing. A business with a good ratio can still run short if big bills are due before big receipts arrive.
They also depend on accurate books. Unreconciled accounts, missing bills or customer balances that will never be collected all distort the result. Clean books come first.
Using them well
Track both ratios monthly and look at the trend, not a single month. Compare them to your own history and, where you can, to similar businesses.
If the numbers slip, ask which part moved: cash, receivables, inventory or short-term debt. Then look at the cause, such as slower customers or a large purchase, before deciding what to change.
A worked comparison
Take two businesses with the same $80,000 of current assets and $40,000 of current liabilities. Both have a current ratio of 2.0. The first holds $60,000 in cash and receivables. The second holds $60,000 in inventory and only $20,000 in cash and receivables.
The first has a quick ratio of 2.0 and the second only 0.5. The second business looks equally healthy on one ratio and weak on the other. This is why it helps to look at both, and to ask what the assets are made of, not only how large they are.
Common questions
What is a good current ratio?
It depends on the industry. A ratio comfortably above 1.0 is common, but compare yours to similar businesses and to your own history.
Why does the quick ratio leave out inventory?
Inventory may take time to sell, so the quick ratio focuses on assets that turn into cash faster.
Do I need these ratios if I have no loan?
They are still useful as a regular health check of your finances.
