5.4.2 Commercial Calculations
Introduction
- Commercial calculations are essential for measuring the financial health and performance of a business.
- They help owners, managers, investors, and creditors make informed decisions.
- Key calculations include:
- Revenue
- Gross Profit
- Gross Profit Margin (%)
- Net Profit (Profit For The Year)
- Working Capital
- Mark-Up Percentage
1. Revenue (Sales Or Turnover)
Formula
Revenue=Selling Price Per Unit×Number Of Units SoldRevenue = Selling Price Per Unit times Number Of Units Sold
Explanation
- Revenue is the total income a business earns from selling goods or services before deducting costs.
- It is the starting point of financial performance.
Example
- A company sells 5,000 shirts at $20 each:
Revenue = 5,000 × 20 = $100,000
Importance
- Shows market demand for a product.
- Basis for all profit calculations.
- Helps businesses plan growth targets.
2. Gross Profit
Formula
Gross Profit=Revenue−Cost Of SalesGross Profit = Revenue – Cost Of Sales
- Cost of Sales = Cost of purchasing or producing goods sold.
Example
- Revenue = $100,000
- Cost of sales = $60,000
- Gross Profit = 100,000 – 60,000 = $40,000
Importance
- Shows profitability before expenses like rent, salaries, or advertising.
- Indicates how efficiently a business produces or buys goods.

3. Gross Profit Margin (%)
Formula
Gross Profit Margin=Gross ProfitRevenue×100Gross Profit Margin = frac{Gross Profit}{Revenue} times 100
Example
- Gross Profit = $40,000
- Revenue = $100,000
- Gross Profit Margin = (40,000 ÷ 100,000) × 100 = 40%
Importance
- Measures profitability as a percentage of sales.
- Useful for comparing performance between businesses or across years.
- Higher margin means goods are sold at higher profit relative to cost.
4. Net Profit (Profit For The Year)
Formula
Net Profit=Gross Profit−ExpensesNet Profit = Gross Profit – Expenses
Explanation
- Expenses include rent, wages, utilities, insurance, advertising, etc.
- Net profit is the final measure of profitability after all costs.
Example
- Gross Profit = $40,000
- Expenses = $25,000
- Net Profit = 40,000 – 25,000 = $15,000
Importance
- Determines if a business is truly profitable.
- Important for investors and shareholders.
- Used to decide dividend payments and reinvestment.

5. Working Capital
Formula
Working Capital=Current Assets−Current LiabilitiesWorking Capital = Current Assets – Current Liabilities
Explanation
- Current assets: cash, inventory, accounts receivable (debts owed to the business).
- Current liabilities: accounts payable, overdrafts, short-term loans.
- Working capital shows the liquidity position — ability to meet short-term obligations.
Example
- Current Assets = $60,000
- Current Liabilities = $40,000
- Working Capital = 60,000 – 40,000 = $20,000
Importance
- Positive working capital = business can pay debts easily.
- Negative working capital = liquidity problems, risk of insolvency.
6. Mark-Up Percentage
Formula
Mark-Up%=(Average Selling Price−Unit Cost)Unit Cost×100Marktext{-}Up% = frac{(Average Selling Price – Unit Cost)}{Unit Cost} times 100
Explanation
- Shows how much extra is added to the cost price to determine the selling price.
Example
- Unit Cost = $50
- Average Selling Price = $70
- Mark-Up = (70 – 50) ÷ 50 × 100 = 40%
Importance
- Ensures business covers costs and earns profit.
- Helps set competitive yet profitable pricing.
- Too high a mark-up may reduce demand; too low may reduce profitability.

Worked Comprehensive Example
Scenario
A bakery sells 10,000 cakes at $5 each. Each cake costs $3 to produce. Expenses include rent ($10,000), wages ($5,000), and utilities ($2,000). Current assets = $25,000. Current liabilities = $18,000.
- Revenue = 10,000 × 5 = $50,000
- Gross Profit = 50,000 – (10,000 × 3) = 50,000 – 30,000 = $20,000
- Gross Profit Margin = (20,000 ÷ 50,000) × 100 = 40%
- Net Profit = 20,000 – (10,000 + 5,000 + 2,000) = 20,000 – 17,000 = $3,000
- Working Capital = 25,000 – 18,000 = $7,000
- Mark-Up % = (5 – 3) ÷ 3 × 100 = 66.7%
Analysis
- The bakery has a good gross margin (40%) but high expenses reduced net profit to only $3,000.
- Positive working capital ($7,000) shows liquidity but thin margins suggest the business should reduce expenses or increase sales volume.
