Quick Ratio vs Cash Ratio
Can your business pay its bills if sales slow down for a while? The quick ratio and the cash ratio both answer that question, but with different levels of caution. This guide explains how each one works, how to calculate them from your balance sheet and which one to watch, with a simple tracker you can copy today.
Key takeaways
- The quick ratio is current assets minus inventory, divided by current liabilities.
- The cash ratio is cash and cash equivalents divided by current liabilities, so it is the stricter of the two.
- The quick ratio counts money customers owe you; the cash ratio counts only money you already have.
- There is no universal "good" number. Track your own trend and compare it with similar businesses and your lender's expectations.
Profit and cash are not the same thing. A business can look profitable on paper and still struggle to pay rent next month if its money is tied up in stock or unpaid invoices. That is why lenders, investors and careful owners look at liquidity ratios: measures of how easily you can cover short-term obligations with assets you can turn into cash quickly.
Two of the most common are the quick ratio and the cash ratio. They sound similar, and they share the same denominator, but they tell slightly different stories. Knowing both helps you spot trouble early and talk confidently with your bank or accountant.
A quick refresher on the balance sheet
Both ratios come from your balance sheet, so it helps to know the terms:
- Current assets: things you own that you expect to turn into cash within about a year. This includes cash, accounts receivable (money customers owe you), inventory and prepaid expenses.
- Current liabilities: what you owe within about a year. This includes supplier bills, short-term loans, credit card balances, taxes due and wages owed.
- Cash equivalents: very short-term, highly liquid investments that can be turned into a known amount of cash almost immediately, such as certain money market holdings.
The broadest liquidity measure is the current ratio, which divides all current assets by current liabilities. The quick ratio and the cash ratio are stricter versions that strip out assets which might be slow or hard to turn into cash.
What the quick ratio measures
The quick ratio, sometimes called the acid-test ratio, asks whether you could cover your short-term bills without selling any inventory. Inventory is excluded because it can take time to sell, and in a hurry you might have to discount it.
Quick ratio = (current assets minus inventory) / current liabilities
What remains in the top half is mostly cash, cash equivalents and accounts receivable. Some analysts also remove prepaid expenses, since you cannot spend a prepaid insurance premium. Whichever version you use, use it consistently and note your method.
When the quick ratio is most useful
The quick ratio is especially helpful for businesses that hold a lot of stock, such as retailers, wholesalers and makers. Their current ratio may look comfortable, but much of it sits on shelves. The quick ratio shows how strong the business looks if that stock moves slowly.
What the cash ratio measures
The cash ratio goes one step further. It ignores inventory and accounts receivable entirely, and asks whether you could pay your short-term bills with the money you already have.
Cash ratio = cash and cash equivalents / current liabilities
This is the most conservative common liquidity measure. It does not assume any customer will pay on time, or at all. It simply compares the cash in your accounts with what you owe soon.
When the cash ratio is most useful
The cash ratio matters most when receivables are uncertain: customers paying slowly, a large client in difficulty or a sector going through a rough patch. It is also a helpful stress test if you are planning a big expense, a slow season or a period of reduced sales.
Pro tip
Calculate both ratios on the same day each month, ideally right after you reconcile your accounts. Consistent timing matters because cash balances can swing a lot between payday and the day a big client pays.
Quick ratio vs cash ratio side by side
| Quick ratio | Cash ratio | |
|---|---|---|
| Formula | (Current assets minus inventory) / current liabilities | Cash and cash equivalents / current liabilities |
| Includes receivables? | Yes | No |
| Includes inventory? | No | No |
| How cautious? | Moderately strict | Very strict |
| Best for | Stock-heavy businesses, routine monitoring | Stress tests, uncertain receivables |
Because the cash ratio leaves out receivables, it will almost always be lower than the quick ratio. A large gap between the two tells you that a lot of your liquidity depends on customers paying you.
A worked example
Let's put real-looking numbers to it.
Example
Imagine Sofia, who runs a small home goods shop with an online store. At the end of July her balance sheet shows cash of $18,000, accounts receivable of $12,000 from wholesale customers and inventory of $40,000, so current assets are $70,000. Her current liabilities are $35,000. Her current ratio is $70,000 / $35,000 = 2.0. Her quick ratio is ($70,000 minus $40,000) / $35,000 = 0.86. Her cash ratio is $18,000 / $35,000 = 0.51. (All figures are made up for illustration.)
What does that tell Sofia? Her current ratio looks comfortable, but most of it is stock. If holiday orders are slow, she would rely heavily on wholesale customers paying on time. Her cash alone covers about half of what she owes in the short term. That is not necessarily a crisis, but it is a clear signal to watch receivables closely and be careful with big stock orders this autumn.
Notice how each ratio changes the conversation. If Sofia only looked at her current ratio, she might feel relaxed enough to place a large holiday order in September. The quick ratio tells her that her comfort depends on wholesale customers paying on time. The cash ratio tells her exactly how much room she has if they do not. With those three numbers in hand, she can decide whether to split her holiday order into two smaller deliveries, chase her two slowest wholesale accounts this month, or ask her bank about a modest credit line before she needs it rather than after.
How to calculate yours
- Reconcile your accounts. Make sure bank balances, receivables and payables are up to date.
- Run a balance sheet as of the last day of the month.
- Note current assets, inventory, cash and current liabilities. Your accounting software usually groups these for you.
- Calculate both ratios. Use the formulas above, or let a spreadsheet do it.
- Record the results in a tracker so you can see the trend.
A simple liquidity tracker template
Copy these columns into a spreadsheet and add one row each month.
| Month | Cash and equivalents | Receivables | Inventory | Current liabilities | Quick ratio | Cash ratio |
|---|---|---|---|---|---|---|
| May (example) | $22,000 | $10,000 | $32,000 | $30,000 | 1.07 | 0.73 |
| June (example) | $20,000 | $11,000 | $36,000 | $32,000 | 0.97 | 0.63 |
| July (example) | $18,000 | $12,000 | $40,000 | $35,000 | 0.86 | 0.51 |
In this made-up example, both ratios are drifting down month by month as stock builds up and liabilities rise. A downward trend like this is worth a conversation long before the numbers look alarming. (For simplicity, current assets here are just cash, receivables and inventory.)
What counts as a good ratio?
You will see rules of thumb online, but there is no single number that suits every business. A healthy ratio depends on your industry, how quickly customers pay, how seasonal your sales are and how reliable your credit lines are. A subscription software business with steady monthly payments can run with very different ratios from a retailer facing a holiday stock build.
Instead of chasing a magic number, focus on three things:
- Your own trend: are the ratios steady, improving or sliding?
- Your lender's expectations: some loan agreements include liquidity or other financial covenants. Read yours and know the figures you need to meet.
- Your known commitments: payroll, tax payments and loan repayments coming in the next few months.
Common mistake
Counting receivables that will never be paid. If an invoice is many months overdue and the customer has gone quiet, it is inflating your quick ratio. Review old receivables and talk to your accountant about writing off ones that are truly lost.
How to strengthen your liquidity
If your ratios are lower than you would like, here are practical levers to pull:
- Collect receivables faster: invoice promptly, send reminders and offer easy online payment.
- Order stock more carefully: buy in smaller, more frequent batches where suppliers allow it.
- Negotiate supplier terms: longer agreed terms reduce pressure on short-term cash.
- Build a cash reserve: move a set amount into a business savings account each month.
- Restructure short-term debt: where it makes sense, longer-term financing can move liabilities out of the current column. Compare the full cost carefully first.
- Cut or pause non-essential spending until the trend turns around.
Keep in mind that a very high cash ratio is not always ideal either. Cash sitting idle could be invested in growth, equipment or paying down expensive debt. The goal is enough liquidity to sleep well, not the maximum possible.
A quick note: this article is general information about financial ratios, not financial advice. If you are making borrowing or investment decisions, speak with your accountant or a qualified adviser who knows your situation.
Your liquidity ratio action plan
- Reconcile your accounts and run a month-end balance sheet
- Calculate your current ratio, quick ratio and cash ratio
- Set up a monthly tracker and add the last three months
- Review receivables for very old or doubtful invoices
- Check any loan agreements for liquidity covenants
- Pick one lever to improve liquidity before the busy season
Frequently asked questions
Which is more important, the quick ratio or the cash ratio?
Both are useful. The quick ratio is a good everyday measure for most businesses. The cash ratio is a sharper stress test, especially when customers are paying slowly or you are planning a lean period.
Do service businesses need the quick ratio?
If you hold little or no inventory, your quick ratio and current ratio will be very close. In that case, the cash ratio often tells you more, because so much of your liquidity depends on clients paying invoices.
Can a ratio below 1 be normal?
Yes, for some businesses. Shops that collect cash at the till and turn stock quickly can run with lower ratios than businesses that wait weeks to get paid. Compare with similar businesses and watch your trend.

The bottom line
The quick ratio shows whether you can cover short-term bills without selling stock. The cash ratio shows whether you can cover them with the cash you already have. Together, they give you an honest picture of how ready your business is for a slow month or a surprise bill.
Calculate both each month, track the trend and act early when the numbers start to slide. Small, steady improvements to collections, stock and cash reserves add up to a business that can handle whatever the next season brings.
