Liquidity ratios are one of the simplest and most useful ways to check how healthy a business really is. They show whether your company can pay its short term bills using the cash and assets it already has. Many UK companies, from small shops to growing limited companies, use these ratios to manage cash flow, plan borrowing, and keep their finances stable during slow periods.
If you run a business, understanding liquidity can help you avoid cash shortages, late payments, and unnecessary debt. This guide explains what liquidity ratios are, how they work, and the most common formulas used by accountants across the UK.
What Are Liquidity Ratios?
Liquidity ratios measure a company’s ability to pay what it owes in the short term. Short term usually means within 12 months. These ratios compare a business’s current assets, such as cash, stock, and money owed by customers, with its current liabilities, which are bills and debts due soon.
A strong liquidity position means you can pay suppliers, wages, tax bills, and other expenses on time without borrowing money in a panic. Weak liquidity can indicate that a business is at risk of missed payments, poor cash flow, or pressure from creditors.
What Is the Liquidity Ratio of a Company?
When people talk about “the liquidity ratio”, they normally mean one of the following:
- Current ratio
- Quick ratio
- Cash ratio
These ratios show slightly different things, but all help answer one key question:
Can the business pay its short term debts when they fall due?
Different industries have different normal ranges. For example, retailers often carry more stock, so their liquidity ratios look different from service-based firms. Understanding your own sector is important before deciding whether your numbers are strong or weak.
Understanding Liquidity Ratios
Liquidity ratios are simple, but they become powerful when combined with regular monitoring, industry benchmarks, and proper accounting records. When used correctly, they help spot cash flow problems early, long before they become serious.
Liquidity Ratio Formula (Overview of Common Formulas)
Here are the three most common liquidity ratio formulas used by UK accountants:
Current Ratio = Current Assets ÷ Current Liabilities
This ratio shows whether your short term assets can cover your short term debts.
Quick Ratio = (Current Assets – Stock) ÷ Current Liabilities
Stock is removed because it may take time to sell. This ratio focuses on assets that can turn into cash quickly.
Cash Ratio = Cash and Cash Equivalents ÷ Current Liabilities
This is the strictest measure. It only looks at cash and near-cash items.
In addition, some businesses track Days Sales Outstanding (DSO) to measure how long customers take to pay.
What Do Liquidity Ratios Measure?
Liquidity ratios answer questions such as:
- Do we have enough cash to pay bills due this month?
- Are we relying too much on credit or overdrafts?
- Are customers taking too long to pay us?
- Can we handle a slow sales period without borrowing?
They are early warning signs. Poor liquidity does not always mean a business is failing, but it does show that action is needed to avoid cash flow strain.
Liquidity Ratio Analysis for UK Companies
When analysing liquidity, UK companies usually consider:
- Industry averages
Some sectors naturally hold more stock or have longer payment cycles. - Seasonality
Retailers, restaurants, and construction firms often have seasonal cash flow patterns. - Payment terms
Long customer credit terms and short supplier terms can weaken liquidity. - Growth stages
Growing businesses often face cash pressure even when profits look strong.
Monitoring liquidity monthly or quarterly helps spot trends and adjust spending, pricing, or working capital before problems arise.
Liquidity vs Solvency: Key Differences
Liquidity and solvency are related but not the same.
- Liquidity looks at short term ability to pay bills.
- Solvency looks at long term financial stability and total debt levels.
A business may be solvent but not liquid. For example, it might own valuable equipment but still struggle to pay wages on time.
On the other hand, a business may be liquid but not solvent if it has heavy long term debt that it cannot repay.
How Liquidity Differs From Solvency
Liquidity relates to:
- Cash flow
- Working capital
- Short term obligations
- Current assets and liabilities
Solvency relates to:
- Total debt
- Long term borrowing
- Assets held for many years
- Long term financial health
The simplest way to remember the difference:
Liquidity is about today. Solvency is about the future.
Why Are There Several Liquidity Ratios?
No single ratio gives the full picture. Each liquidity ratio answers a different question:
- Current ratio shows overall short term strength.
- Quick ratio shows how well you can pay bills without selling stock.
- Cash ratio shows what you can pay immediately.
- DSO shows how quickly customers pay invoices.
Using multiple ratios gives a more accurate view of cash flow health.
Types of Liquidity Ratios
Below are the four most commonly used liquidity ratios for UK businesses.
Current Ratio
The current ratio is the most widely used measure of liquidity. It compares all short term assets to all short term liabilities.
Formula:
Current Assets ÷ Current Liabilities
Example:
If a business has £100,000 in current assets and £50,000 in current liabilities:
Current Ratio = 100,000 ÷ 50,000 = 2.0
This means the business has £2 of assets for every £1 of liabilities.
General guidance:
- Below 1.0 may indicate cash flow pressure.
- Between 1.2 and 2.0 is common for many industries.
- Above 2.0 may suggest assets are not being used efficiently.
Quick Ratio (Acid Test Ratio)
This ratio removes stock from current assets because stock may take time to sell.
Formula:
(Current Assets – Stock) ÷ Current Liabilities
It is useful for service businesses or companies with slow-moving stock.
Example:
If current assets are £80,000, stock is £20,000, and current liabilities are £40,000:
Quick Ratio = (80,000 – 20,000) ÷ 40,000 = 1.5
Cash Ratio
The cash ratio is the strictest test. It only looks at cash and near-cash items like bank balances and short term deposits.
Formula:
Cash and Cash Equivalents ÷ Current Liabilities
Example:
If cash is £30,000 and current liabilities are £60,000:
Cash Ratio = 30,000 ÷ 60,000 = 0.5
This shows the business cannot cover all short term debts with cash alone, which is normal for most companies.
Days Sales Outstanding (DSO)
DSO measures how long it takes customers to pay invoices.
Formula (simplified):
(Trade Receivables ÷ Total Credit Sales) × Number of Days
A lower DSO means customers pay faster.
A higher DSO can cause cash flow strain even if sales are strong.
For example:
- Under 30 days is considered good for many UK service businesses.
- Over 60 days may indicate payment issues or slow credit control.
“Unofficial” and Related Liquidity Metrics
Apart from the main formulas, accountants sometimes use additional liquidity indicators, such as:
- Working capital (Current Assets – Current Liabilities)
- Operating cash flow ratio
- Short term debt coverage ratio
These are not official liquidity ratios, but they support a more complete cash flow assessment. They help businesses see how much cash is tied up, how sales convert into cash, and whether short term borrowing is being used too heavily.
Liquidity Ratio Examples
Liquidity ratios become far easier to understand when applied to real numbers from everyday business scenarios. Below are practical examples that demonstrate how different ratios work, what their results mean, and how analysts interpret them in real situations. These examples use neutral, fictional companies to ensure clarity without referencing real brands.
Real-Life Liquidity Ratio Calculations
- Current Ratio Example
Formula: Current Assets ÷ Current Liabilities
A company has:
- Current Assets: £300,000
- Current Liabilities: £150,000
Current Ratio = 300,000 ÷ 150,000 = 2.0
This means the business has £2 in short-term assets for every £1 it owes.
- Quick Ratio Example
Formula: (Current Assets − Inventory) ÷ Current Liabilities
A retailer holds:
- Current Assets: £500,000
- Inventory: £200,000
- Current Liabilities: £250,000
Quick Ratio = (500,000 − 200,000) ÷ 250,000 = 1.2
This means the company can cover its immediate liabilities without relying heavily on inventory sales.
- Cash Ratio Example
Formula: (Cash + Cash Equivalents) ÷ Current Liabilities
A service provider has:
- Cash + Cash Equivalents: £70,000
- Current Liabilities: £120,000
Cash Ratio = 70,000 ÷ 120,000 = 0.58
This means the business can cover 58% of immediate debts using only its cash reserves.
- Days Sales Outstanding (DSO) Example
Formula: (Trade Receivables ÷ Credit Sales) × Days
A B2B company has:
- Annual Credit Sales: £1,200,000
- Receivables: £100,000
DSO = (100,000 ÷ 1,200,000) × 365 = 30.4 days
This suggests customers pay their invoices within about 30 days, indicating healthy cash flow.
What Does a Liquidity Ratio of 1.5 Mean?
A liquidity ratio of 1.5 generally indicates that:
- The business has £1.50 in liquid assets for every £1 owed, showing acceptable liquidity.
- It is not excessively cash-heavy, nor dangerously underfunded.
- Most lenders consider a ratio above 1.2 as financially stable.
A ratio of 1.5 is particularly strong in industries with predictable revenue, such as consulting or software, but may be considered only moderate in retail or manufacturing, where cash flow demands are higher.
What Does a 30% Liquidity Ratio Mean?
A 30% liquidity ratio generally refers to the cash ratio or similar measurement of immediate liquidity.
A 30% liquidity level means:
- The company can cover 30% of its short-term liabilities with cash alone.
- It will likely need receivables or inventory sales to meet obligations.
- It may signal tight liquidity if the business operates in a volatile market.
However, high-growth startups often operate with low cash liquidity because funds are invested into expansion rather than reserves.
Is a Liquidity Ratio of 2 Good?
Yes, a liquidity ratio of 2.0 is typically considered strong.
It means:
- The business can pay short-term debts twice over.
- It has a substantial liquidity buffer.
- Lenders view the company as low risk.
However, an excessively high ratio (e.g., above 3.0) might indicate poor asset utilisation, signalling that cash is sitting idle instead of being invested into growth.
Example Companies (Liquids Inc., Solvents Co.)
Liquids Inc.
- Current Assets: £800,000
- Inventory: £300,000
- Current Liabilities: £400,000
Current Ratio: 800,000 ÷ 400,000 = 2.0
Quick Ratio: (800,000 – 300,000) ÷ 400,000 = 1.25
Liquids Inc. has solid liquidity, but holds significant inventory, suggesting it relies heavily on product turnover.
Solvents Co.
- Current Assets: £350,000
- Inventory: £50,000
- Current Liabilities: £300,000
Current Ratio: 350,000 ÷ 300,000 = 1.17
Quick Ratio: (350,000 – 50,000) ÷ 300,000 = 1.0
Solvents Co. has lower liquidity but is more efficient with inventory and maintains a balanced quick ratio that still supports obligations.
Why Liquidity Ratios Matter
Liquidity ratios are crucial indicators of a company’s short-term financial health, operational resilience, and capacity to manage unexpected expenses. They are used by auditors, investors, analysts, and business owners to assess risk and long-term viability.
Ability to Cover Short-Term Obligations
A strong liquidity ratio demonstrates that:
- A business can pay suppliers on time.
- Staff salaries and operating costs are covered.
- The company can withstand temporary drops in revenue.
Weak liquidity is often the first warning sign of impending cash-flow issues.
Determining Creditworthiness
Banks and lenders rely heavily on liquidity ratios to evaluate risk. A higher ratio means:
- Lower likelihood of default
- Better loan approval chances
- Lower interest rates in many cases
Lenders seldom approve financing to businesses that cannot demonstrate sufficient liquidity to repay short-term debt obligations.
Investment Worthiness and Financial Stability
Investors analyse liquidity ratios to determine whether a company:
- Can continue operating during downturns
- Has manageable debt levels
- Is using cash efficiently
A company with strong liquidity ratios typically attracts more investor confidence because it signals operational discipline and financial control.
Faster Access to Financial Insights
Liquidity ratios allow decision-makers to:
- Monitor cash flow in real time
- Identify early warning signs
- Compare performance across months or years
These metrics are simple, easily calculated, and provide clear insight into financial stability.
What Happens If Ratios Show a Company Is Not Liquid?
A company with poor liquidity may face:
- Delayed supplier payments
- Difficulty paying wages
- Loss of credit terms
- Higher borrowing costs
- Operational disruption
- Potential insolvency
Several companies fail not because they are unprofitable, but because they run out of cash, liquidity issues account for most business closures.
Who Uses Liquidity Ratios?
Liquidity ratios are not limited to accountants; they are used by multiple stakeholders who want to understand risk, stability, and financial control.
Business Owners and Directors
Directors use liquidity ratios to:
- Improve cash-flow planning
- Manage expenses
- Decide whether expansion is feasible
- Ensure compliance with financial duties
A director with poor oversight of liquidity risks breaching UK corporate governance standards.
Accountants and Financial Analysts
These specialists use liquidity ratios for:
- Financial reporting
- Forecasting
- Valuation analysis
- Risk determination
- Audit preparation
Liquidity assessments are a key part of any professional financial review.
Lenders, Banks, and Investors
External parties use liquidity ratios to:
- Evaluate funding applications
- Compare investment opportunities
- Assess repayment ability
- Set borrowing limits
Strong liquidity significantly improves the chances of securing funding on favourable terms.
Liquidity Ratio Tools and Calculators
Modern tools simplify financial analysis and eliminate calculation errors, allowing business owners to get quick insight into performance.
Using a Liquidity Ratio Calculator
A liquidity ratio calculator allows users to input:
- Current assets
- Inventory
- Cash
- Liabilities
It automatically produces:
- Current ratio
- Quick ratio
- Cash ratio
- Liquidity percentages
These calculators support decision-making by offering instant, accurate results.
How to Use Ratios in Financial Models
In financial modelling, liquidity ratios help:
- Predict cash-flow shortages
- Simulate worst-case scenarios
- Assess financial resilience
- Optimise debtor and creditor terms
They also assist in building investment projections and refining budget strategies.
Understanding Liquidity Benchmarks
Benchmarks vary depending on industry norms. Examples:
- Technology: Ratios between 1.2 and 2.0 are standard
- Retail: Lower ratios common due to fast inventory turnover
- Manufacturing: Higher ratios recommended due to capital intensity
Comparing ratios only makes sense when measured within the same industry.
Advantages and Disadvantages of Liquidity Ratios
Liquidity ratios are helpful tools, but they have limitations and should be interpreted carefully.
Advantages
- Clear measure of short-term financial health
- Useful for lenders and investors
- Easy to calculate
- Helps forecast cash-flow issues
- Indicates operational efficiency
Liquidity ratios contribute to strategic planning and preventive action.
Disadvantages
- Ratios vary significantly by industry
- They do not show long-term stability
- Inventory values may distort results
- Extremely high ratios may signal inefficiency
They should never be used in isolation for major decisions.
Limitations of Liquidity Ratios
- Based on book values, not market values
- Lack real-time precision
- May not reflect cash-flow timing differences
- Cannot predict unexpected financial shocks
Proper interpretation requires context and comparison with other ratios.
Special Considerations
Liquidity analysis must account for industry-specific and seasonal variations.
Industry-Specific Liquidity Variations
Every industry has its own liquidity norms:
- Hospitality businesses often operate with lower ratios
- Manufacturing requires high working capital
- Professional services operate with fewer assets, resulting in higher liquidity
Therefore, comparing a retail store with an engineering firm is misleading.
Seasonal and Cash Flow Influences
Examples of seasonal impacts:
- Retail spikes during holidays
- Construction slows during winter
- Tourism varies with seasonal travel patterns
Ratios should be analysed across multiple periods to avoid false conclusions.
Why Good Liquidity Ratios Differ Across Sectors
A “good” ratio depends on:
- Payment cycles
- Inventory turnover speed
- Customer credit terms
- Supply chain structure
For example:
A supermarket may function efficiently with a ratio of 0.8, while a consultancy firm may require a ratio above 1.5 for stability.
