For financial reporting, apply the standards and policies applicable to your entity. Primary references ↓ The short answer What business terms must an owner know? Start with revenue, gross and net profit, cash flow, break-even, fixed and variable costs, working capital, receivables and payables. Then learn customer acquisition cost, lifetime value, margins, EBITDA, return on capital and valuation. Together they explain how a business earns, spends, collects and creates value. 30 Essential terms 6 Decision areas 1 Worked business case Business owners often hear that sales increased by 30%, margins dropped two points or working capital absorbed cash. Those observations only become useful when the underlying terms are defined consistently and connected to an operating decision. This guide distinguishes accounting measures from management metrics. Each entry includes a meaning, a practical formula or rule, a numerical example, and an owner’s check to prevent common misinterpretations. Unless otherwise stated, figures are hypothetical and use no specific currency. Find a term in this guide Type to filter the 30 terms by name or explanation. SECTION 01 / 06 · TERMS 01–05 The financial foundations The five numbers that tell you whether sales are becoming an actual business. 01 Revenue # The value of goods or services sold and recognised in the period under the applicable accounting rules; not necessarily cash collected. FORMULA / RULE Revenue = recognised sales after applicable returns, discounts and relevant sales adjustments. IN PRACTICE A shop delivers 1,000 units at 100 each with no returns or discounts. Recognised revenue is 100,000 even if some invoices remain unpaid. Owner’s check: Compare sales to collections. A signed order, customer deposit and completed sale are not automatically the same thing. 02 Gross profit # Revenue remaining after deducting cost of goods sold (COGS) or the directly attributable cost of delivering the product or service. FORMULA / RULE Gross profit = revenue − COGS. IN PRACTICE Revenue of 100,000 less direct product costs of 60,000 produces gross profit of 40,000. Owner’s check: Check which costs were classified into COGS. A high gross profit can still disappear under rent, staff, technology and financing costs. 03 Net profit # The residual earnings after expenses, finance costs, taxes and any other recognised gains or losses affecting the period. FORMULA / RULE Net profit = total income − all recognised expenses and tax (simplified). IN PRACTICE Revenue of 100,000 ultimately produces net profit of 7,500 in the worked business below: net margin is 7.5%. Owner’s check: Net profit is an accounting outcome, not the amount sitting in the bank. Separate one-off gains and unusually low costs. 04 Cash flow # The actual change in cash generated or used by operating, investing and financing activities over a period. FORMULA / RULE Closing cash = opening cash + net cash movement (subject to currency and other cash-equivalent adjustments). IN PRACTICE A profitable wholesaler may struggle to pay salaries if large customers take 90 days to settle invoices. Owner’s check: Read cash from operations separately from loans or owner injections. Borrowed cash is not evidence of profitable operations. 05 Break-even point # The sales volume or revenue level at which total contribution covers the fixed costs included in the chosen break-even measure. FORMULA / RULE Break-even units = fixed costs ÷ (selling price per unit − variable cost per unit). IN PRACTICE If a product sells for 100, costs 60 per unit and fixed operating costs are 28,000, break-even is 700 units. Owner’s check: Use consistent cost classifications and time periods. Accounting break-even, cash break-even and financing-inclusive break-even can differ. SECTION 02 / 06 · TERMS 06–10 Costs and operating decisions Understand which costs move with demand, which remain, and where capital is tied up. 06 Fixed costs # Costs that are broadly unchanged across a relevant range of activity during a defined period. FORMULA / RULE Total fixed cost stays broadly constant within the relevant range; fixed cost per unit falls as volume increases. IN PRACTICE A monthly warehouse lease of 4,000 usually remains 4,000 whether 500 or 800 units are shipped. Owner’s check: Fixed does not mean permanent. Rent resets, step-up staff costs and capacity expansions can change the cost base. 07 Variable costs # Costs that change with output or sales activity, often roughly in proportion to the number of units. FORMULA / RULE Total variable cost = variable cost per unit × units, assuming a stable unit cost. IN PRACTICE Packaging costing 3 per shipment means 900 of packaging at 300 shipments and 1,500 at 500 shipments. Owner’s check: A cost can be partly fixed and partly variable. Split mixed expenses before pricing a product. 08 Operating expenses (OpEx) # Costs incurred in running the business, commonly referring in management reports to selling, administrative and other operating overheads outside COGS. FORMULA / RULE In a simplified P&L: operating profit = gross profit − operating expenses, including depreciation where classified. IN PRACTICE Marketing, office rent, administrative salaries and software subscriptions may sit in OpEx rather than product COGS. Owner’s check: Accounting presentation and industry practice vary. Do not confuse operating expenditure with total cash outflow. 09 Capital expenditure (CapEx) # Spending to acquire, improve or create long-lived assets where accounting recognition criteria are met. FORMULA / RULE CapEx is generally recorded as an asset initially and recognised through depreciation/amortisation or impairment as applicable. IN PRACTICE A machine costing 20,000 may be capitalised instead of charged fully to this month’s profit. Owner’s check: A capital purchase still consumes cash today. Check the asset policy and do not treat every large invoice as CapEx. 10 Working capital # The amount by which current assets exceed current liabilities at a given date; a broad indicator of near-term financial position. FORMULA / RULE Working capital = current assets − current liabilities. IN PRACTICE Cash 20,000 + receivables 20,000 + inventory 25,000 − current liabilities 40,000 = working capital of 25,000. Owner’s check: Positive working capital may be locked in slow inventory or overdue bills. Review timing and collectability, not just the total. SECTION 03 / 06 · TERMS 11–15 Cash, collections and runway A profitable company can still fail to meet obligations. These five measures explain why. 11 Accounts receivable (AR) # Amounts owed by customers for recognised sales made on credit, subject to appropriate adjustments for expected non-payment. FORMULA / RULE Closing AR = opening AR + credit invoices − collections − write-offs/adjustments (simplified). IN PRACTICE A customer receives a 20,000 invoice on 30-day credit. Until payment arrives, the amount is generally a receivable, not bank cash. Owner’s check: Track ageing buckets, disputes and concentration. An overdue invoice is not as useful as collected cash. 12 Accounts payable (AP) # Amounts owed to suppliers for goods or services received on credit. FORMULA / RULE Closing AP = opening AP + credit purchases − supplier payments ± adjustments. IN PRACTICE If materials costing 8,000 have been received but payment is due next month, a payable generally arises. Owner’s check: Monitor actual due dates. Stretching suppliers may improve cash briefly while damaging terms, supply reliability or discounts. 13 Inventory turnover # The number of times average inventory is sold or consumed, typically measured using COGS over a chosen period. FORMULA / RULE Inventory turnover = COGS ÷ average inventory; average inventory often = (opening + closing inventory) ÷ 2. IN PRACTICE COGS of 60,000 with average inventory of 15,000 gives annual turnover of 4 times. Owner’s check: Compare like periods and product categories. A high turnover can indicate efficiency—or stockouts. 14 Burn rate # How quickly a business consumes cash. Net burn usually describes the amount by which cash payments exceed cash receipts in a period. FORMULA / RULE Net monthly burn = monthly cash outflows − monthly cash inflows, when positive. IN PRACTICE Cash outflows of 40,000 and inflows of 30,000 create net monthly burn of 10,000. Owner’s check: Specify whether you mean gross or net burn; include recurring financing needs and seasonal movements. 15 Runway # The estimated time remaining before unrestricted available cash is exhausted at an assumed net cash burn rate. FORMULA / RULE Runway (months) ≈ available cash ÷ monthly net burn, only when net burn is positive. IN PRACTICE With 60,000 of usable cash and recurring net burn of 10,000 per month, indicative runway is 6 months. Owner’s check: This is a scenario, not a guarantee. Upcoming debt repayments, tax dues, revenue seasonality and restricted cash change it. SECTION 04 / 06 · TERMS 16–20 Sales, customers and growth More customers are not always better customers. Measure the economics of acquiring and retaining them. 16 Customer acquisition cost (CAC) # The average acquisition-related spend required to gain one new customer during the measurement period. FORMULA / RULE CAC = attributable sales and marketing acquisition costs ÷ new customers acquired. IN PRACTICE If acquisition spending is 10,000 and 50 first-time paying customers are gained, CAC is 200. Owner’s check: Be consistent about payroll, agency fees, discounts and attribution. Comparing CAC across channels requires similar definitions. 17 Customer lifetime value (LTV) # An estimate of the economic value generated by a customer across the relationship; revenue-based and gross-profit-based versions differ. FORMULA / RULE Simplified gross-profit LTV ≈ revenue per customer per period × gross margin × expected active periods. IN PRACTICE At 300 annual revenue, 60% gross margin and a 3-year relationship, simplified gross-profit LTV is 540 before acquisition cost. Owner’s check: It is a forecast, not cash already earned. Retention, servicing costs, discounting and cohort differences matter. 18 Conversion rate # The share of a defined group completing a specified action within a stated period. FORMULA / RULE Conversion rate = completed desired actions ÷ eligible prospects or sessions × 100. IN PRACTICE 40 purchases from 1,000 website sessions give a 4% session-to-purchase conversion rate. Owner’s check: Do not mix unique visitors, sessions, leads and orders. Set one denominator and time period. 19 Churn rate # The proportion of existing customers or recurring revenue lost over a period, measured on a clearly defined basis. FORMULA / RULE Customer churn = customers lost during period ÷ customers at start of period × 100. IN PRACTICE If 100 subscribers start the month and 5 cancel, monthly customer churn is 5%, excluding new subscribers from the denominator. Owner’s check: Customer churn and revenue churn differ. A few high-value cancellations can hurt more than many small ones. 20 Average order value (AOV) # The average value of an order placed during a period under a consistent sales-value definition. FORMULA / RULE AOV = eligible order revenue ÷ number of eligible orders. IN PRACTICE Net order revenue of 20,000 from 100 completed orders gives an AOV of 200. Owner’s check: An AOV increase caused by discounts, returns or higher fulfilment costs may not improve contribution profit. SECTION 05 / 06 · TERMS 21–25 Profitability and unit economics These metrics expose whether a business earns enough from every sale and from capital already committed. 21 Gross margin # Gross profit expressed as a percentage of revenue. FORMULA / RULE Gross margin = gross profit ÷ revenue × 100. IN PRACTICE Gross profit of 40,000 on revenue of 100,000 produces gross margin of 40%. Owner’s check: A falling margin may signal price discounts, rising input costs or changing product mix. Compare consistent COGS classifications. 22 Operating margin # Operating profit (often EBIT) expressed as a percentage of revenue. FORMULA / RULE Operating margin = operating profit ÷ revenue × 100. IN PRACTICE Operating profit of 12,000 on revenue of 100,000 produces a 12% operating margin. Owner’s check: Check the operating-profit definition; businesses report some items differently. This is not net margin or cash margin. 23 EBITDA # Earnings before interest, taxes, depreciation and amortisation; often used as an additional operating-performance measure. FORMULA / RULE EBITDA = earnings + interest + tax + depreciation + amortisation, using a consistently reconciled earnings base. IN PRACTICE Net profit 7,500 + interest 2,000 + tax 2,500 + depreciation 4,000 = EBITDA 16,000. Owner’s check: EBITDA is not cash flow and omits capital spending and working-capital changes. Adjusted EBITDA may use different exclusions. 24 Return on investment (ROI) # The return or gain relative to the amount invested for a clearly defined investment and time period. FORMULA / RULE Simple ROI = net gain attributable to investment ÷ investment cost × 100. IN PRACTICE A campaign costing 10,000 that produces incremental net gain of 2,000 after that campaign cost has a simple ROI of 20%. Owner’s check: Specify whether gain is incremental profit or revenue; keep the denominator and time horizon consistent. 25 Contribution margin # The portion of sales left after variable costs, available to cover fixed costs and then profit. FORMULA / RULE Contribution per unit = selling price − variable cost per unit; contribution ratio = contribution ÷ revenue. IN PRACTICE At price 100 and variable cost 60, contribution is 40 per unit or 40% of the selling price. Owner’s check: Gross profit and contribution are not automatically identical: they group fixed production costs differently. SECTION 06 / 06 · TERMS 26–30 Finance, risk and business value Understand financing pressure, capital efficiency and what might make earnings durable. 26 Return on capital employed (ROCE) # A measure of operating earnings relative to the capital used by the business. FORMULA / RULE ROCE ≈ EBIT ÷ average capital employed × 100; capital employed can be defined as total assets − current liabilities. IN PRACTICE EBIT of 12,000 against capital employed of 80,000 gives illustrative ROCE of 15% using closing capital. Owner’s check: For period returns, average capital employed is often more informative. Disclose the definition and compare peers carefully. 27 Debt-to-equity ratio # A leverage comparison between debt and shareholders’ equity; definitions differ in whether debt includes only borrowings or wider liabilities. FORMULA / RULE Borrowings-to-equity = interest-bearing borrowings ÷ total equity. IN PRACTICE Interest-bearing debt of 30,000 and equity of 50,000 produces a borrowing-to-equity ratio of 0.60×. Owner’s check: Always state which liabilities were included. Negative or very low equity can make the ratio misleading. 28 Depreciation # The systematic allocation of a depreciable tangible asset’s cost over its estimated useful life. FORMULA / RULE Straight-line annual depreciation = (asset cost − estimated residual value) ÷ useful life. IN PRACTICE A 20,000 machine with zero residual value and a 5-year useful life has straight-line depreciation of 4,000 a year. Owner’s check: Depreciation is not a cash payment each year. Asset impairment, useful-life changes and tax deductions follow different rules. 29 Valuation # An estimate of what a business or its equity is worth under defined assumptions, valuation methods and circumstances. FORMULA / RULE Illustrative enterprise value = EBITDA × selected EV/EBITDA multiple; equity value ≈ enterprise value − net debt ± other adjustments. IN PRACTICE At 16,000 EBITDA and a hypothetical 8× multiple, enterprise value is 128,000; with net debt 10,000, indicative equity value is 118,000 before adjustments. Owner’s check: The multiple is only an assumption. Actual valuation depends on risk, growth, cash generation, comparables, ownership and transaction terms. 30 Economic moat # A durable, demonstrable competitive advantage that helps a business defend its economics against competitors over time. FORMULA / RULE No universal formula: evaluate evidence such as switching costs, cost advantage, network effects or sustained pricing power. IN PRACTICE A niche software firm whose customers face high switching costs might retain pricing power despite competing products. Owner’s check: A recognisable brand alone is not proof of a moat. Look for long-term renewal, margins, customer behaviour and competitor response. One business · multiple connected metrics Worked case study: Northstar Goods A simplified illustrative one-year income statement and a year-end balance sheet. This example makes the arithmetic traceable; it does not represent a real company. Statement of profit or loss · one year Line item Amount Revenue (1,000 units × 100) 100,000 Cost of goods sold (60,000) Gross profit 40,000 Operating costs excl. depreciation (24,000) Depreciation (4,000) Operating profit / EBIT 12,000 Finance cost (2,000) Illustrative income tax expense (2,500) Net profit 7,500 Balance sheet · end of year Line item Amount Cash 20,000 Accounts receivable 20,000 Inventory 25,000 Non-current assets 55,000 Total assets 120,000 Accounts payable 25,000 Other current liabilities 15,000 Long-term interest-bearing debt 30,000 Shareholders’ equity 50,000 Total liabilities + equity 120,000 40% Gross margin = 40,000 / 100,000 12% Operating margin = 12,000 / 100,000 7.5% Net margin = 7,500 / 100,000 16,000 EBITDA = 12,000 + 4,000 depreciation 25,000 Working capital = 65,000 current assets − 40,000 current liabilities 0.60× Borrowings / equity = 30,000 / 50,000 15% Indicative ROCE = 12,000 / 80,000 closing capital employed; average capital not provided 700 units Accounting operating break-even = 28,000 fixed costs / 40 contribution per unit* 118,000 Hypothetical equity valuation = 16,000 EBITDA × 8 − 10,000 net debt, before adjustments *Break-even assumption: The 60,000 COGS is assumed entirely variable (60 per unit); the 24,000 of other operating costs and 4,000 depreciation are assumed fixed. This yields 28,000 fixed cost and 40 unit contribution. The hypothetical valuation multiple is not a market observation, recommendation or accepted value. Cash flow cannot be inferred from this P&L and closing balance sheet alone. What to review every month A concise owner’s agenda. Use the checklist to make each term lead to an action, rather than treating it as vocabulary. Do revenue and gross profit move together? If not, isolate price, mix and cost changes. Is net profit supported by actual operating cash collection? How many days are customer invoices overdue, and which balances are disputed? Which supplier payments and tax obligations fall due within 30 days? How much capital is stuck in old or slow-moving inventory? Which fixed costs could be resized without damaging critical capability? Are acquisition costs recoverable from customer gross profit in a reasonable period? Are conversion, AOV and customer churn improving on consistent bases? Did a CapEx purchase improve capacity or merely add a future cash burden? Does the business still have adequate cash and borrowing headroom under a downside case? Five mistakes to avoid 1. Treating revenue as cash. Credit sales may create receivables, not available bank balances. 2. Confusing margin with markup. A product bought for 60 and sold for 100 has a 40% gross margin but a 66.7% markup on cost. 3. Treating EBITDA as free cash. Debt service, tax, capex and working-capital needs can absorb a large portion of cash. 4. Comparing metrics with different denominators. A churn rate per month, CAC per new customer and LTV per cohort must each have a stated basis. 5. Reading one ratio in isolation. Debt-to-equity, ROCE and valuation multiples require context, time periods and cash-flow assessment. Frequently asked questions What are the five most important business terms for a new owner? Start with revenue, gross profit, net profit, cash flow and break-even point. Together they show sales, direct economics, bottom-line earnings, liquidity and the minimum sales needed to cover costs. What is the difference between revenue and profit? Revenue is the recognised value of sales before business expenses. Profit is what remains after deducting the relevant costs. A business can grow revenue while profit declines. Can a profitable business run out of cash? Yes. Receivables, inventory purchases, debt repayments, tax payments and capital expenditure can use cash even while the income statement shows a profit. Is EBITDA the same as cash flow? No. EBITDA does not automatically capture changes in receivables, inventory, payables, capital spending, interest or tax payments. It should be reconciled to accounting earnings and assessed alongside cash flow. Which numbers should an owner review every month? Review revenue, gross margin, operating profit, net profit, cash from operations, collections ageing, payables due, working capital, customer acquisition cost and customer retention. The exact scorecard depends on the business model. How can an owner compare CAC and LTV? Calculate both consistently, ideally by customer cohort and acquisition channel. Use a gross-profit-based LTV if comparing the relationship’s economic contribution with acquisition cost, and account for time to recover CAC. Does a higher debt-to-equity ratio always mean a weak business? No. Capital intensity, interest coverage, stable cash flows, borrowing cost and industry norms matter. A ratio without a stated debt definition and supporting cash analysis can mislead. Does an 8× EBITDA multiple determine the value of every business? No. It is only an illustrative assumption. Actual valuation requires evidence about growth, industry, profitability quality, cash conversion, comparable transactions and risk.
