When you're analyzing a business, you need to know more than just "is this company making money?" You need to evaluate financial health, operational efficiency, investment effectiveness, and long-term sustainability using specific, standardized metrics. These are diagnostic tools that reveal how and why a business succeeds or struggles.
The metrics in this guide fall into distinct categories: profitability, efficiency, liquidity, leverage, and customer/employee dynamics. Don't just memorize formulas. Understand what each metric reveals about a company's operations and how different metrics connect to paint a complete picture. When an exam asks you to evaluate a company's performance, you'll need to select the right metrics for the situation and explain what they indicate.
These metrics answer the fundamental question: Is this business making money, and how effectively? They measure how well a company converts revenue into actual profit at different stages of the income statement.
Revenue is the total income a company earns from sales. It sits at the top line of the income statement and serves as the starting point for all profitability analysis.
Revenue growth shows whether a business is expanding its market presence and customer base. But revenue alone doesn't tell you much. A company pulling in $50 million in revenue might still be losing money if its costs hit $55 million. You always need to evaluate revenue alongside expenses.
Gross Profit Margin is the percentage of revenue left after subtracting the cost of goods sold (COGS):
This metric tells you how efficiently a company produces or sources its products. A gross margin of 60% means that for every dollar of revenue, 60 cents remain after covering direct production costs. It also reflects pricing strategy: if a company raises prices without increasing production costs, gross margin goes up.
Net Profit Margin is the percentage of revenue remaining after all expenses, including operating costs, taxes, and interest. This is the "bottom line" profitability measure.
Higher net margins suggest better overall cost management and a stronger competitive position. A company with a 15% net margin keeps 15 cents of profit from every dollar of revenue after everything is paid.
Compare: Gross Profit Margin vs. Net Profit Margin — both measure profitability as a percentage of revenue, but gross margin only considers production costs while net margin includes all expenses. If you see a high gross margin paired with a low net margin, that signals problems with operating expenses (like rent, salaries, or marketing), not production.
Return metrics evaluate how effectively a company uses its resources to generate profit. Each one measures efficiency from a different perspective: investors, managers, or shareholders.
ROI measures profitability relative to the cost of an investment:
It's a universal comparison tool. You can use it to compare completely different types of investments or projects. If Project A has an ROI of 25% and Project B has an ROI of 10%, Project A generated more profit per dollar invested. Higher ROI means more effective capital allocation.
ROA measures profit generated per dollar of assets:
This shows how efficiently management deploys company resources. It's especially useful for comparing companies in asset-heavy industries like manufacturing or retail, where firms invest heavily in equipment, property, and inventory.
ROE measures profit generated from shareholder investment:
This is the metric shareholders care about most. It shows how effectively equity financing creates value and is often used to compare companies within the same industry.
Compare: ROA vs. ROE — ROA evaluates all assets while ROE focuses on shareholder equity. A company with high ROE but low ROA is likely using significant debt to amplify returns for shareholders. This distinction comes up frequently in exam questions about financial structure.
These metrics help investors evaluate a company's value and competitive position. They translate company performance into terms that matter for investment decisions.
EPS is the profit allocated to each share of stock:
Because it's calculated on a per-share basis, EPS allows comparison across companies of different sizes. Rising EPS typically drives stock price increases and signals growing profitability to investors.
Market Share is the percentage of total industry sales controlled by one company. It's a competitive positioning metric.
A growing market share suggests effective marketing, pricing, or product strategies. It also reflects brand strength and customer preference. For example, if the smartphone industry generates $500 billion in sales and one company accounts for $100 billion, that company holds a 20% market share.
Compare: EPS vs. Market Share — EPS measures internal financial performance while market share measures external competitive position. A company can have strong EPS but declining market share (profiting from existing customers without growing) or growing market share with weak EPS (spending heavily on expansion).
These metrics measure the human side of business performance: how effectively a company acquires, retains, and manages its most important relationships.
CAC is the total cost to acquire one new customer, including marketing, sales, and related expenses. Lower CAC indicates more efficient customer acquisition strategies.
CAC on its own doesn't tell you whether spending is justified. You have to compare it against how much revenue that customer will eventually generate (that's where CLV comes in).
CLV is the total expected revenue from one customer over the entire relationship. It's a long-term profitability projection.
Higher CLV suggests strong customer loyalty and repeat purchasing. It also helps businesses determine how much they can reasonably spend to acquire and retain customers. A subscription service where the average customer stays for 3 years at $20/month has a CLV of $720.
Employee Turnover Rate is the percentage of employees leaving and requiring replacement, typically measured annually. High turnover often signals problems with management, compensation, or workplace culture.
Turnover is also a hidden cost driver. Every departure means spending on recruiting, training, and absorbing productivity losses while new hires get up to speed.
Compare: CAC vs. CLV — these metrics work as a pair. The CLV:CAC ratio reveals whether customer relationships are profitable. A ratio below 3:1 often indicates unsustainable acquisition spending (you're paying too much to acquire customers relative to what they'll generate). Exam questions frequently ask you to evaluate both together.
Efficiency metrics reveal how well a company manages its operational resources, particularly inventory and cash flow. They connect daily operations to financial outcomes.
Inventory Turnover Ratio measures how many times inventory is sold and replaced per period:
Higher ratios suggest strong demand and efficient stock control. This metric varies significantly by industry: a grocery store might turn inventory 15+ times per year, while a furniture retailer might turn it only 4-5 times. Always compare within the same sector.
Operating Cash Flow is the cash generated from core business operations, excluding financing and investing activities. It shows whether the business generates enough cash to fund day-to-day operations.
This metric is a reality check. A company can show profit on paper while running dangerously low on actual cash. Positive operating cash flow is essential for paying bills, employees, and suppliers regardless of what accounting profits say.
Compare: Net Profit vs. Operating Cash Flow — a company can report profit while struggling with cash flow due to timing differences between when revenue is recognized and when payment is actually received. If a company books a $1 million sale in December but doesn't collect payment until March, December looks profitable but cash is tight.
These metrics assess how a company finances its operations and manages financial risk. They reveal the balance between debt, equity, and liquidity.
Debt-to-Equity Ratio compares total liabilities to shareholder equity:
This shows how much a company relies on borrowed money versus owner investment. A ratio of 2.0 means the company has twice as much debt as equity. Lower ratios suggest more conservative financing and less vulnerability to economic downturns, though some industries (like utilities) naturally carry higher debt.
Current Ratio measures the ability to pay short-term obligations:
A ratio above 1.0 means the company has enough short-term assets to cover its near-term debts. A ratio of 2.0 means it has twice the assets needed. However, a ratio that's too high may indicate the company isn't using its assets efficiently (sitting on too much idle cash, for example).
Compare: Debt-to-Equity Ratio vs. Current Ratio — both assess financial health, but debt-to-equity measures long-term capital structure while current ratio measures short-term liquidity. A company can have a healthy current ratio but dangerous debt-to-equity levels, or vice versa.

A company has a high gross profit margin but a low net profit margin. What does this suggest about where the company's financial problems lie?
Which two "return" metrics would you compare to determine whether a company is using significant debt leverage, and what pattern would indicate high leverage?
Compare and contrast CAC and CLV. Why must these metrics be evaluated together rather than in isolation?
