Cost, Revenue & Profit Essentials

State currency and time period when presenting each figure.

Revenue Streams

Total Revenue (TR)

TR = Selling Price × Quantity Sold

Average Revenue (AR)

AR = TR / Quantity

Cost Structures

Total Cost (TC)

TC = Fixed Costs + Variable Costs

Average Cost (AC)

AC = TC / Quantity

Average Fixed Cost (AFC)

AFC = Fixed Costs / Quantity

Average Variable Cost (AVC)

AVC = Variable Costs / Quantity

Profitability

Profit

Profit = TR − TC

Gross Profit

Gross Profit = Sales Revenue − Cost of Sales

Net Profit

Net Profit = Gross Profit − Expenses

Contribution & Break-even

Contribution per Unit

Contribution = Selling Price − Variable Cost per unit

Total Contribution

Total Contribution = Contribution per unit × Quantity

Break-even Output

Break-even = Fixed Costs / Contribution per unit

Margin of Safety

Margin of Safety = Actual Output − Break-even Output

Profitability & Liquidity Ratios

Ratios should be expressed as percentages or ratios depending on syllabus guidance.

Profitability Ratios

Capital Employed = Long-term liabilities + Shareholders' funds.

Gross Profit Margin

Gross Profit Margin = (Gross Profit / Sales Revenue) × 100%

Net Profit Margin

Net Profit Margin = (Net Profit / Sales Revenue) × 100%

Return on Capital Employed (ROCE)

ROCE = (Net Profit / Capital Employed) × 100%

Liquidity Ratios

Aim for 1.5:1 (current ratio) and at least 1:1 (acid test) for exam evaluation.

Current Ratio

Current Ratio = Current Assets / Current Liabilities

Acid Test Ratio

Acid Test = (Current Assets − Inventory) / Current Liabilities

Inventory Turnover

Average Inventory = (Opening Inventory + Closing Inventory) / 2.

Inventory Turnover = Cost of Goods Sold / Average Inventory

Receivables & Payables Days

Receivables Days

Receivables Days = (Trade Receivables / Credit Sales) × 365

Payables Days

Payables Days = (Trade Payables / Credit Purchases) × 365

Marketing Metrics

Market Demand Calculations

Market Size (value)

Market Size = Total Market Sales × Average Price

Market Size (volume)

Market Size = Total units sold in the market

Market Share

Market Share = (Firm's Sales / Total Market Sales) × 100%

Pricing Decisions

Mark-up Percentage

Mark-up = ((Selling Price − Cost) / Cost) × 100%

Margin Percentage

Margin = ((Selling Price − Cost) / Selling Price) × 100%

Price Elasticity of Demand

PED = (% Δ in quantity demanded) / (% Δ in price)

Use to predict impact of price changes on revenue.

Average Rate of Return (ARR)

Average Annual Profit = Total profit over project ÷ number of years.

ARR (%) = (Average Annual Profit / Initial Investment) × 100

Payback Period

Time taken for cumulative cash inflow to equal initial investment.

No formal formula; subtract annual inflows until investment is recovered, then compute remainder as a proportion of the next year's inflow.

Operations & Human Resource Analytics

Productivity Measures

Labour Productivity

Labour Productivity = Output / Number of Employees

Output per Machine

Output per Machine = Total Output / Number of Machines

Capacity Utilisation

Capacity Utilisation (%) = (Actual Output / Maximum Possible Output) × 100

Quality Metrics

Defect Rate

Defect Rate (%) = (Number of Defective Units / Total Units Produced) × 100

Human Resource Calculations

Labour Turnover

Labour Turnover (%) = (Number of Staff Leaving / Average Number of Staff Employed) × 100

Absenteeism Rate

Absenteeism (%) = (Number of Days Lost / Total Possible Working Days) × 100

Labour Cost per Unit

Labour Cost per Unit = Total Labour Cost / Number of Units Produced

Working Capital Management

Working Capital

Working Capital = Current Assets − Current Liabilities

Net Cash Flow

Net Cash Flow = Cash Inflow − Cash Outflow

Closing Cash Balance

Closing Balance = Opening Balance + Net Cash Flow
