Analysing financial performance and position using key accounting ratios.

Learning Objectives

Concept Framework

What are Accounting Ratios?

Accounting ratios are relationships between financial figures used to evaluate business performance.

They help users analyse:

• profitability
• liquidity
• efficiency

1. Profitability Ratios

Measure how effectively a business generates profit.

Gross Profit Margin

 
Gross Profit ÷ Revenue × 100
 

Net Profit Margin

 
Net Profit ÷ Revenue × 100
 

2. Liquidity Ratios

Measure the ability to meet short-term obligations.

Current Ratio

 
Current Assets ÷ Current Liabilities
 

Acid Test Ratio

 
(Current Assets − Inventory) ÷ Current Liabilities
 

3. Efficiency Ratios

Measure how effectively resources are used.

Inventory Turnover

 
Cost of Sales ÷ Average Inventory
 

Trade Receivables Collection Period

 
Trade Receivables ÷ Revenue × 365

Profitability:
Gross Profit Margin
Net Profit Margin

Liquidity:
Current Ratio
Acid Test Ratio

Efficiency:
Inventory Turnover
Receivables Collection Period

🧠 “PNL → CA/CL → Efficiency”

 
STEP 1 → Profitability (Income Statement)

Gross Profit ÷ Revenue × 100
Net Profit ÷ Revenue × 100

————————————–

STEP 2 → Liquidity (Current Position)

Current Assets ÷ Current Liabilities
(Current Assets − Inventory) ÷ Current Liabilities

————————————–

STEP 3 → Efficiency (Usage of Resources)

Cost of Sales ÷ Average Inventory
Trade Receivables ÷ Revenue × 365
 

📌 QUICK MEMORY FORMULAS

Profitability

 
Gross Profit Margin = GP ÷ Revenue × 100
Net Profit Margin = NP ÷ Revenue × 100
 

Liquidity

 
Current Ratio = CA ÷ CL
Acid Test = (CA − Inventory) ÷ CL
 

Efficiency

 
Inventory Turnover = COS ÷ Avg Inventory
Receivables Days = Receivables ÷ Revenue × 365
 

⚡ ULTRA-SHORT MEMORY TRICK

 
Profit → Sales
Liquidity → CA/CL
Efficiency → Speed
 

📊 INTERPRETATION QUICK GUIDE

 
HIGH GP% → Good pricing / low cost
LOW NP% → High expenses

HIGH Current Ratio → Safe liquidity
LOW Current Ratio → Risk of cash shortage

HIGH Inventory Turnover → Fast sales
LOW Turnover → Slow-moving stock

HIGH Receivable Days → Slow collection
LOW Receivable Days → Good credit control
 

⚠ COMMON EXAM MISTAKES

 
• Forgetting ×100 in margins
• Using profit instead of revenue
• Not subtracting inventory in acid test
• Mixing receivables with payables

📊 GOOD vs BAD RATIO BENCHMARK TABLE

🧠 Use this for Interpretation Questions


🔹 Profitability Ratios

 
Gross Profit Margin (GP%)

High → Good pricing / low cost of sales
Low → Poor pricing or high cost of sales

—————————————

Net Profit Margin (NP%)

High → Good cost control
Low → High expenses / poor control
 

🔹 Liquidity Ratios

 
Current Ratio

Ideal → Around 2 : 1
Too High → Idle resources / inefficient use
Too Low → Risk of liquidity problems

—————————————

Acid Test Ratio

Ideal → Around 1 : 1
Too High → Excess liquid assets
Too Low → Difficulty paying short-term debts
 

🔹 Efficiency Ratios

 
Inventory Turnover

High → Fast sales / efficient stock management
Low → Slow-moving or obsolete inventory

—————————————

Receivables Collection Period

Low (fewer days) → Quick cash collection
High (more days) → Poor credit control
 

⚡ QUICK EXAM INTERPRETATION RULE

 
Profitability → Higher is usually better

Liquidity → Balanced is best (not too high, not too low)

Efficiency → Faster is better
 

🧠 SUPER MEMORY LINE

 
Profit → High
Liquidity → Balanced
Efficiency → Fast
 

⚠ EXAM TIP (VERY IMPORTANT)

Never just say:

❌ “This is good”
❌ “This is bad”

Always say:

✔ what it means
✔ why it happened
✔ its effect on the business

Example:

A low net profit margin indicates high operating expenses, which reduces overall profitability.

Ratios must be interpreted, not just calculated.
Examples:
• High profit margin → good cost control
• Low current ratio → liquidity risk
• Slow receivables → poor credit control

Worked Examples

Revenue = £100,000
Gross Profit = £40,000
Net Profit = £20,000


Gross Profit Margin

 
40,000 ÷ 100,000 × 100 = 40%
 

Net Profit Margin

 
20,000 ÷ 100,000 × 100 = 20%
 

Current Assets = £50,000
Current Liabilities = £25,000


Current Ratio

 
50,000 ÷ 25,000 = 2 : 1

Structured Practice

Level 1 – Concept Check

Define accounting ratio.

State one profitability ratio.

State one liquidity ratio.

Revenue = £80,000
Net Profit = £16,000

Calculate net profit margin.

      1. 1. Explain why ratio analysis is useful to a business owner.  (4 marks) …… 📌 Additional structured questions are available in the 🎯 Lesson wise resources, Module wise resources, Guess Question Papers + YouTube Explanation section.</p>

Enrolled students may submit questions from recognised textbooks, past examination papers or other genuine academic material for expert clarification through the Student Doubt Support facility.

Proficiency Check

Learn → Unlearn → Relearn

Students who believe they understand this topic should attempt:

  1. Explain why ratios must be interpreted and not just calculated.
  2. Revenue = £120,000
    Gross Profit = £60,000

    Calculate gross profit margin.

  3. Explain one limitation of ratio analysis.

If unsure, review the lesson.

Detailed Activity Solutions

Solution to Level 2 question

16,000 ÷ 80,000 × 100 = 20%

60,000 ÷ 120,000 × 100 = 50%
