Module 1: Introduction to Revenue and Costs
Introduction to Revenue and Costs
Knowledge check
Q1. What is revenue in a business?
- A. The total cost of producing goods or services
- B. The total income earned from selling goods or services ✓
- C. The profit left after all expenses are paid
- D. The money a business owes to its suppliers
Why: Revenue is the total income a business generates from its sales of goods or services before any costs are subtracted.
Q2. Which of the following is an example of a fixed cost?
- A. Raw materials used in production
- B. Sales commissions paid per unit sold
- C. Monthly rent for a store ✓
- D. Packaging materials for each product
Why: Fixed costs remain the same regardless of how much a business produces or sells, and monthly rent is a classic example.
Q3. What is the formula for profit?
- A. Revenue + Costs
- B. Revenue - Costs ✓
- C. Costs - Revenue
- D. Revenue / Costs
Why: Profit is calculated by subtracting total costs from total revenue, showing what the business keeps after paying its expenses.
Q4. Which cost changes in direct proportion to the number of units produced?
- A. Fixed cost
- B. Variable cost ✓
- C. Overhead cost
- D. Sunk cost
Why: Variable costs rise or fall with production volume, such as materials and labor paid per unit.
Q5. If a bakery earns $5,000 in revenue and has $3,500 in total costs, what is its profit?
- A. $8,500
- B. $1,500 ✓
- C. $3,500
- D. $5,000
Why: Profit equals revenue minus costs: $5,000 - $3,500 = $1,500.
Module 2
Module 2: Types of Business Expenses
Types of Business Expenses
Knowledge check
Q1. Which of the following is an example of a fixed expense for a small business?
- A. Raw materials used in production
- B. Monthly office rent ✓
- C. Sales commissions based on revenue
- D. Packaging costs for each product sold
Why: Fixed expenses stay the same regardless of how much a business sells. Monthly office rent is a set amount due each month, whereas the other options change with production or sales volume.
Q2. Which expense is classified as a variable expense?
- A. Annual insurance premium paid in one lump sum
- B. Salary of a full-time bookkeeper
- C. Electricity costs that rise with higher production ✓
- D. Property tax on the company building
Why: Variable expenses change in proportion to business activity. Electricity usage typically increases when production increases, while the other options remain relatively constant.
Q3. Which of the following is considered a cost of goods sold (COGS)?
- A. Advertising campaign expenses
- B. Office supplies like paper and pens
- C. Wholesale cost of inventory sold to customers ✓
- D. Accounting software subscription
Why: Cost of goods sold includes the direct costs of producing or purchasing the items a business sells, such as the wholesale cost of inventory. Advertising, office supplies, and software are operating expenses, not COGS.
Q4. Depreciation is best described as:
- A. A cash payment made to suppliers each month
- B. The allocation of a fixed asset's cost over its useful life ✓
- C. A fee paid to the government for business licenses
- D. The interest paid on a business loan
Why: Depreciation spreads the cost of a long-lived asset, such as equipment or a vehicle, across the years it is used. It is a non-cash expense recorded on the income statement.
Q5. Which of the following is an operating expense rather than a cost of goods sold?
- A. Materials used to manufacture a product
- B. Direct labor of factory workers
- C. Utilities for the corporate headquarters ✓
- D. Shipping costs to deliver products to customers
Why: Operating expenses cover the costs of running the business that are not tied directly to producing goods. Headquarters utilities support general operations, while the other options are directly tied to production or delivery of goods.
Module 3
Module 3: Calculating Gross Profit
Calculating Gross Profit
Knowledge check
Q1. What is the formula for gross profit?
- A. Revenue + Cost of Goods Sold
- B. Revenue - Cost of Goods Sold ✓
- C. Revenue - Operating Expenses
- D. Net Income - Taxes
Why: Gross profit is calculated by subtracting the Cost of Goods Sold (COGS) from total revenue. It shows how much money remains after paying the direct costs of producing the goods sold.
Q2. A shop has sales revenue of $10,000 and cost of goods sold of $6,000. What is its gross profit?
- A. $4,000 ✓
- B. $16,000
- C. $6,000
- D. $3,000
Why: Gross profit = Revenue - COGS = $10,000 - $6,000 = $4,000.
Q3. Which of the following is included in Cost of Goods Sold?
- A. Rent for the office building
- B. Advertising expenses
- C. Raw materials used in production ✓
- D. Owner's salary
Why: COGS includes the direct costs of producing goods, such as raw materials and direct labor. Rent, advertising, and owner salaries are operating expenses, not COGS.
Q4. What does a higher gross profit margin generally indicate?
- A. The business has high overhead costs
- B. The business retains more money from each sale after direct costs ✓
- C. The business has sold fewer goods
- D. The business owes more in taxes
Why: Gross profit margin (Gross Profit / Revenue x 100) shows the percentage of each sales dollar kept after direct costs. A higher margin means more money is retained per sale to cover operating expenses and profit.
Q5. A company earns revenue of $50,000 with a gross profit of $20,000. What is its gross profit margin?
- A. 40% ✓
- B. 60%
- C. 25%
- D. 250%
Why: Gross profit margin = (Gross Profit / Revenue) x 100 = ($20,000 / $50,000) x 100 = 40%.
Module 4
Module 4: Understanding Operating Expenses
Understanding Operating Expenses
Knowledge check
Q1. Which of the following is an example of an operating expense?
- A. Purchase of new manufacturing equipment
- B. Monthly office rent ✓
- C. Repayment of a bank loan principal
- D. Dividends paid to shareholders
Why: Operating expenses are the costs incurred in running a business day to day, such as rent, utilities, and salaries. Monthly office rent is a recurring operating cost, while equipment purchases are capital expenditures, loan principal repayments are financing activities, and dividends are distributions of profit.
Q2. Where do operating expenses appear on an income statement?
- A. Above gross profit, as part of the cost of goods sold
- B. Below operating income, as part of non-operating items ✓
- C. Between revenue and gross profit only
- D. After net income, as a reconciling item
Why: Operating expenses are subtracted from gross profit to arrive at operating income. They sit below gross profit and above net income, which is why they are central to measuring how efficiently a core business runs.
Q3. Which of these is classified as a selling, general, and administrative (SG&A) expense?
- A. Raw materials used in production
- B. Direct labor for assembling products
- C. Marketing and advertising costs ✓
- D. Freight charges for inbound inventory
Why: SG&A expenses include costs of selling and running the overall business, such as marketing, advertising, executive salaries, and administrative overhead. Raw materials, direct labor, and inbound freight are generally part of cost of goods sold instead.
Q4. A company pays $3,000 for an annual software subscription on January 1. How should this be recorded in the monthly operating expenses for January?
- A. The full $3,000 as an expense in January
- B. Nothing in January, since it was paid in advance
- C. $250 as an expense in January, with the rest recognized over the remaining months ✓
- D. $3,000 as an asset with no expense recognized
Why: Under the matching principle, expenses are recognized in the period the benefit is used. Spreading the $3,000 over 12 months gives $250 per month, so January carries $250 of expense while the remainder is held as a prepaid asset.
Q5. Why is it important for a business to track operating expenses carefully?
- A. Because operating expenses are never tax deductible
- B. Because they directly reduce operating income and affect profitability ✓
- C. Because they are excluded from the profit and loss statement
- D. Because they only matter for companies that sell physical products
Why: Operating expenses are subtracted from revenue to determine profit, so rising or uncontrolled costs shrink operating income and net profit. Tracking them helps managers spot inefficiencies and make pricing and budgeting decisions.
Module 5
Module 5: Measuring Net Profit
Measuring Net Profit
Knowledge check
Q1. What is the basic formula for calculating net profit?
- A. Revenue + Expenses
- B. Revenue - Expenses ✓
- C. Expenses - Revenue
- D. Revenue / Expenses
Why: Net profit is found by subtracting total expenses (including costs of goods sold, operating costs, interest, and taxes) from total revenue. A positive result means the business earned a profit; a negative result means a loss.
Q2. A business has total revenue of $50,000 and total expenses of $42,000. What is its net profit?
- A. $92,000
- B. $8,000 ✓
- C. $42,000
- D. $50,000
Why: Net profit = Revenue - Expenses = $50,000 - $42,000 = $8,000. Adding the two figures would be incorrect, and the expense or revenue figures alone do not represent profit.
Q3. Which of the following is considered an operating expense?
- A. Rent for the business office ✓
- B. Cash received from a customer sale
- C. Money invested by the owner
- D. Income from selling old equipment
Why: Rent is an ongoing cost of running the business, so it is an operating expense that reduces net profit. Customer sales and owner investments are revenue or capital sources, not expenses, and selling old equipment is a gain rather than an operating cost.
Q4. What does a net loss indicate?
- A. Revenue is greater than expenses
- B. Expenses are greater than revenue ✓
- C. Revenue equals expenses exactly
- D. The business has no expenses
Why: A net loss occurs when total expenses exceed total revenue over the same period. Revenue exceeding expenses produces a profit, and when the two are equal the net result is zero, not a loss.
Q5. Why is net profit considered an important measure of business performance?
- A. It shows only the cash in the bank
- B. It shows what remains after all costs are paid, indicating true earnings ✓
- C. It includes only the owner's personal income
- D. It ignores taxes and interest completely
Why: Net profit reflects the earnings left after all costs, including taxes and interest, are covered. This gives a clear picture of how profitable the business truly is, unlike gross revenue or cash balances, which can be misleading.

Module 6: Reading a Profit and Loss Statement
Reading a Profit and Loss Statement
Knowledge check
Q1. What is the basic formula for net profit on a profit and loss statement?
- A. Revenue + Expenses
- B. Revenue - Expenses ✓
- C. Expenses - Revenue
- D. Assets - Liabilities
Why: Net profit is calculated by subtracting total expenses from total revenue. If the result is positive, the business made a profit; if negative, it recorded a loss.
Q2. Which line item on a profit and loss statement shows the income earned from selling goods or services before any expenses are deducted?
- A. Gross profit
- B. Net income
- C. Revenue (or sales) ✓
- D. Operating expenses
Why: Revenue, also called sales, is the total income a business earns from its core activities before any costs are subtracted.
Q3. What does gross profit represent on a profit and loss statement?
- A. Revenue minus the cost of goods sold ✓
- B. Revenue minus all taxes paid
- C. Total cash held by the business
- D. Revenue plus operating expenses
Why: Gross profit is revenue minus the cost of goods sold (COGS), showing how much money remains from sales after paying for the direct costs of producing the products or services.
Q4. Which of the following is typically classified as an operating expense?
- A. Rent for the office space ✓
- B. Sales revenue from customers
- C. A loan received from a bank
- D. Equipment purchased for long-term use
Why: Rent is an ongoing day-to-day cost of running the business, so it is an operating expense. Sales revenue is income, bank loans are liabilities, and long-term equipment is usually recorded as an asset.
Q5. If a company has revenue of $50,000 and total expenses of $62,000, what does its profit and loss statement show?
- A. A net profit of $12,000
- B. A net loss of $12,000 ✓
- C. A net profit of $112,000
- D. A net loss of $112,000
Why: Subtracting expenses of $62,000 from revenue of $50,000 gives -$12,000, which is a net loss of $12,000 because expenses exceed revenue.

Knowledge check
Q1. Which line on a profit and loss statement shows the money left after subtracting the cost of goods sold from revenue?
- A. Operating expenses
- B. Gross profit ✓
- C. Net income
- D. Depreciation
Why: Gross profit is calculated by subtracting the cost of goods sold (COGS) from total revenue. It shows how efficiently a business produces or buys what it sells, before overhead and other expenses are considered.
Q2. A business has revenue of $50,000, cost of goods sold of $30,000, and operating expenses of $12,000. What is its net income?
- A. $8,000 ✓
- B. $20,000
- C. $38,000
- D. $62,000
Why: Gross profit is $50,000 minus $30,000, which equals $20,000. Subtracting operating expenses of $12,000 from $20,000 gives a net income of $8,000.
Q3. If a company's gross profit margin is steadily declining while its revenue stays flat, what is the most likely explanation to investigate first?
- A. Rising costs of goods sold or falling selling prices ✓
- B. Increased marketing spending
- C. A new tax regulation
- D. Higher owner salaries
Why: Gross profit margin depends on revenue relative to cost of goods sold. If revenue is flat and the margin falls, either production or purchasing costs have risen, or prices have dropped, squeezing the margin. Marketing, taxes, and owner pay usually appear below gross profit and do not directly affect it.
Q4. Why is it useful for a manager to compare P&L statements across several months or years rather than looking at a single period?
- A. Single periods are always inaccurate
- B. Trends reveal whether performance is improving, declining, or seasonal ✓
- C. The law requires multi-period comparisons
- D. It eliminates the need for a balance sheet
Why: One period can be distorted by a one-time event or seasonality. Comparing several periods reveals trends, so managers can tell whether changes are sustained and plan accordingly.
Q5. A P&L shows that operating expenses rose sharply this quarter while revenue grew only slightly. What is the best decision-making response?
- A. Ignore it because revenue increased
- B. Investigate which expenses rose and whether the increase is justified by expected returns ✓
- C. Immediately double prices
- D. Remove the expense category from future statements
Why: Using P&L data well means identifying the cause of changes. Determining which expenses drove the increase and whether they will produce future revenue or savings lets managers decide whether to adjust spending, rather than reacting blindly.
