Last month I published the first article of this five-part series about financial KPIs. Part A focused on profitability measures derived from the income statement. In this second article, I will discuss liquidity KPIs and why they are essential for maintaining a company's financial flexibility.
As mentioned previously, financial KPIs are essential for building financial visibility in any business. Because assessing financial health requires consideration of different aspects of the organization, there are different categories of KPIs. The main groups I am covering in this series of articles include: profitability, liquidity, cash flow, efficiency and growth.
What is liquidity?
Liquidity is the ability of a business to pay its short-term obligations with existing cash or with assets that can be converted into cash in the short term.   Measuring business liquidity answers questions such as: Do I have enough cash and near-cash assets to meet my upcoming obligations on time? 

Liquidity vs. Cash Flow
Before digging into liquidity KPIs, I would like to explain the difference between the two metrics.   Why? Because both groups of indicators analyze the availability of cash in the business but from two different perspectives.
Liquidity is about having enough accessible cash to meet obligations, while cash flow is about the timing and movement of cash into and out of the business. Cash flow metrics answer questions related to the capacity of the business to provide cash, or the need to absorb cash.
For example, a residential contractor could have strong profitability and positive cash flow over a year but still experience a liquidity problem if payroll and supplier payments are due before customer progress payments are collected. Conversely, a business could have good liquidity today because it has a healthy cash balance or line of credit, while having poor operating cash flow because its operations consistently consume more cash than they generate.
There can be some overlap, particularly in manufacturing businesses where inventory is a significant part of operations. In service industries such as construction, however, the distinction is often more meaningful because cash flow depends less on inventory and more on project execution, billing, collections, and contract terms.

Liquidity and Profitability
Why liquidity matters more than profitability in the short term.
As discussed in the article about profitability KPIs, net profit is the bottom line because the ultimate purpose of a business is to generate returns for owners and investors.  Net profit margin shows how many cents of each revenue dollar remain as profit.  However, profit does not say when the money from revenue will be available, as a significant portion can remain uncollectible.   In the short term, this can impact operations of the business if vendors and contractors cannot be paid to continue contractual operations or if there are no funds to cover essential administrative expenses such as payroll.

Liquidity KPIs measure how efficiently a business can convert its assets, primarily current assets, into cash to meet its short-term obligations.  This article will cover three types of liquidity KPIs:

A.	 Balance sheet liquidity – the ability to meet short-term liabilities using current assets.
B.	 Working-capital liquidity – how quickly resources tied up in receivables and inventory are converted into cash, and how supplier payment terms affect that timing.
C. 	Financing liquidity – the availability of external financing when additional liquidity is needed.

The balance sheet to the right shows sample data that will be used to illustrate calculations of the liquidity KPIs.

A.	 Balance Sheet Liquidity
1.	Current RatioCurrent ratio measures the company's ability to pay short-term obligations using current assets. The number shows how many dollars of current assets the company has for every dollar of obligations due within a year.

Current Ratio =Current Assets ÷ Current Liabilities

This indicator also provides a useful way to assess liquidity: A result above 1.0 indicates that the current assets are enough to cover short-term liabilities.  Depending on the industry and business model, the result between 1.5 and 2.0 is often considered healthy.  On the other hand, a result below 1.0 indicates that the company needs to find additional liquid resources to meet its short-term needs.

Using ABC LLC balance sheet data, the business shows strong liquidity as their current ratio is 2.0
Current Ratio: 600,000 ÷ 300,000 = 2.0

2.	Quick Ratio (Acid Test)
Quick ratio is a more conservative measurement than current ratio.  It excludes prepaid expenses, as these resources cannot be used for existing liabilities.  It also excludes inventory because it is usually less liquid than other current assets and it requires a sale before becoming liquid.

Quick Ratio = (Current Assets – Inventory – Prepaid Expenses) ÷ Current Liabilities

This indicator is important because it focuses on the ability to meet current liabilities with cash and cash-like assets, as well as AR.  It is especially useful for inventory-heavy businesses.

Using our example, ABC LLC shows a positive Quick Ratio of 1.5, meaning that the business is liquid, even after excluding inventory and other current assets (assumed to be prepaid expenses).

Quick Ratio: (150,000 + 300,000) ÷ 300,000 = 1.5


3.	Cash Ratio
Cash ratio measures the company's ability to pay obligations using only cash.

Cash & Cash Equivalents ÷ Current Liabilities

This is probably the most conservative indicator of liquidity, and it is useful during periods of financial stress, as it measures the ability to pay liabilities immediately.  Using our example, ABC LLC has enough cash to pay for half of its current liabilities.

ABC LLC Cash Ratio: 150,000 ÷ 300,000 = 0.5


4.	Working Capital
Working capital represents the net resources available to run daily operations.  In other words, it is the amount that is not tied to existing short-term obligations and can be used to pay operating expenses.

Working Capital = Current Assets – Current Liabilities

This indicator can be used to evaluate short-term financial flexibility.    Although there are some exceptions to the rule, businesses depend on positive working capital to fund their ongoing operations.   In other words, most businesses need to maintain enough cash, accounts receivable, and inventory levels, not only to cover existing short-term liabilities, but also to fund day-to-day expenses of the company.  Negative working capital can create a need for other sources of liquidity to help meet liabilities and maintain ongoing operations.

For ABC LLC, working capital at the end of the year is: 600,000 − 300,000 = $300,000


5.	Net Working Capital (NWC) Percentage 
NWC % shows how much working capital is available to support continuous operations for each dollar of revenue, after considering current liabilities. 

NWC % = Working Capital ÷ Revenue

Assuming that ABC LLC had a net revenue of $3M, then the net working capital percentage would be 10%, which means that every dollar of net revenue the company produces $0.10 of working capital available to support ongoing operations.


B.	 Working Capital Liquidity
The following three indicators help explain how quickly resources tied up in working capital are converted into cash and how payment timing affects liquidity. They are called working capital indicators because they provide visibility into the timing and movement of resources within working capital elements: accounts receivable, inventory and accounts payable.  
6.	 Accounts Receivable Days (DSO)
DSO is the average number of days required to collect receivables. It answers the question: How quickly are clients paying for credit sales?

Two-step calculation:
Average Accounts Receivable = ( Beginning AR + Ending AR ) / 2
DSO =  (Average AR / Total Credit Sales) x Number of Days (365)

The indicator alone provides information about collection timing. When considered together with DPO and DIO, it helps management understand how the timing of cash inflows and outflows affects liquidity. DSO is very important because slow collections can reduce liquidity.

Alternatively, there is the Accounts Receivable Turnover, which is calculated as: Net Credit Sales ÷ Average Accounts Receivable
A high ratio means cash is collected relatively quickly. If collections are slow (low ratio), cash is trapped in unpaid invoices, affecting the ability to meet business obligations.


7.	 Accounts Payable Days (DPO)
DPO shows how many days, on average, the business takes to pay vendors and suppliers. It answers the question: How long do we take to pay suppliers?

Two steps:
Average Accounts Payable: (Beginning AP + Ending AP) / 2 
DPO = (Average Accounts Payable / Purchases) x Number of Days (365)
When compared with DIO and DSO, DPO helps identify whether payment terms with vendors and credit terms offered to clients are helping to decrease the cash gap.   Extending payment terms can improve liquidity, but excessive delays may strain supplier relationships.

There is also an optional complementary KPI to DPO which is the Accounts Payable Turnover, which is calculated as: Purchases ÷ Average Accounts Payable
Accounts Payable Turnover indicates how quickly the business pays vendors in relation to its purchases.

8.	 Days Inventory Outstanding (DIO)
DIO provides the average number of days inventory remains in the business before being sold. It measures how long cash is tied up in inventory.  
It is also a two-step calculation:
Average Inventory = ( Beginning Inventory + Ending Inventory ) / 2
DIO = ( Average Inventory / COGS) x Number of Days 365

This indicator provides visibility into how quickly inventory moves through the business cycle. If sales slow down, inventory piles up, and working capital shortage start to rise because slow-moving inventory ties up cash.

As with DSO and DPO, Inventory Turnover is an alternative way to measure inventory efficiency.
Inventory Turnover = Cost of Goods Sold (COGS) ÷ Average Inventory
It calculates how many times the business sells and replaces its inventory during a period.

C.	Financing Liquidity
For the purpose of this article, I will cover only one financial liquidity indicator to illustrate how other sources of liquidity other than current assets, can be measured.

9.	 Available Line of Credit Utilization
This indicator shows how much of the company's available short-term borrowing capacity is already being used.

Line of Credit Utilization = Outstanding Line of Credit ÷ Total Available Line of Credit

For example, ABC LLC has a $250,000 line of credit and is currently using $100,000. Its line of credit utilization is:
$100,000 ÷ $250,000 = 40%
This means ABC LLC is currently using 40% of its available borrowing capacity and has $150,000, or 60%, still available.
A line of credit can provide an additional source of liquidity when the timing of cash inflows and outflows does not match. This can be particularly important for growing businesses, where increasing sales may require additional working capital before the related cash is collected. Monitoring utilization helps management understand how much financing capacity remains available if the business needs additional liquidity.﻿
A high utilization rate may indicate that the company is relying heavily on external financing to support its operations. It can also mean that there is less borrowing capacity available to address unexpected cash needs or future growth.
A low utilization rate generally means that more borrowing capacity remains available. However, a low utilization rate does not necessarily mean that the business has strong liquidity—it is important to consider this KPI together with cash balances, working capital, cash flow, and upcoming obligations.

The objective is not necessarily to minimize line of credit utilization, but to understand how much financing capacity is available and how much of it the business may need to support its operations and growth.

 Additional suggestions:
Choosing the right liquidity indicators is essential for building the financial infrastructure needed to create financial visibility. The goal is not to monitor every possible KPI, but to identify the indicators that provide useful information for the decisions you make every day.
This article is meant to be a tool to identify which KPIs are most relevant to the liquidity challenges and growth objectives of your business.
One common mistake when incorporating KPIs into a dashboard is to focus too heavily on predetermined thresholds. A ratio that is considered healthy for one business may not be appropriate for another. A better approach is to understand what has historically worked for the business model, monitor trends over time, and identify the range that provides enough resources to meet existing obligations while maintaining smooth operations.
As you go through this series, I encourage you to consider developing a KPI dashboard and selecting from each article the indicators that are most relevant to your day-to-day decisions. The objective is not to create a dashboard full of numbers. It is to create enough financial visibility to support better decisions.
