Sometimes, appearing financially savvy is all about optimizing your efforts, not increasing your workload.

By mastering these financial terms and concepts, you'll bolster your ability to make informed decisions, manage your business effectively, and engage confidently with financial professionals and stakeholders.

1. Return on Investment (ROI)

Return on Investment (ROI) is a pivotal metric used to assess the profitability of an investment. It serves two primary purposes: firstly, to gauge the expected or actual returns of a current or future investment, and secondly, as a post-analysis tool to evaluate the investment's profitability retrospectively.

Ways to Express ROI:

  • As a ratio

  • As a percentage

  • As a multiple (e.g., 5x or 10x, commonly used when ROI exceeds 100%)

ROI Formulas (Two Equivalent Methods):

ROI = (Net Profit / Cost of Investment) x 100

ROI = ([Present Value — Cost of Investment] / Cost of Investment) x 100

When to Use ROI as a Small Business Owner:

As a small business owner, ROI is a fundamental metric for assessing the worth of various initiatives. You'll employ ROI as an estimate before embarking on a project or incurring an expense to project its potential value to your business. Additionally, you'll use ROI post-implementation to determine if your investment of time, resources, or capital was justified.

Common applications of ROI include evaluating investments in equipment, personnel (hiring employees), marketing campaigns, product launches, opening physical stores, and investing in larger inventory or purchase orders.

2. Return on Advertising Spend (ROAS)

Return on Advertising Spend (ROAS) is a financial ratio designed to assess the profitability of your advertising expenditures, focusing specifically on ad spending's impact.

How to Calculate ROAS:

ROAS = (Gross Revenue from Ad Spend — Advertising Cost)

Determining a Good ROAS:

ROAS of 4x (equivalent to 400%) is considered a standard benchmark for online advertising spending. However, the ideal ROAS varies from one business to another. Some businesses may require a higher ROAS to remain profitable, while others can maintain profitability with a lower ROAS. E-commerce businesses, for instance, often work with lower ROAS values since they lack the additional costs associated with brick-and-mortar retailers.

3. Working Capital

Working capital, also known as cash flow, refers to a business's liquid assets. It can be assessed using either the net working capital ratio (current assets divided by current liabilities) or simply net working capital (current assets minus current liabilities).

Working Capital Formulas:

  • Net Working Capital = Current Assets — Current Liabilities

  • Working Capital Ratio = Current Assets / Current Liabilities

Working capital calculations focus on determining if you have sufficient cash on hand to cover impending expenditures. Therefore, it's essential to include short-term assets in your working capital, such as available cash (e.g., in your business bank account) and accounts receivable expected to be realized within the next year.

When calculating current liabilities for your working capital, consider items like salaries, taxes, and accounts payable (outstanding amounts owed to vendors, credit card balances, etc.).

Why Working Capital Matters for Entrepreneurs:

Working capital is a critical financial concept for entrepreneurs as it offers insights into the short-term financial health of your business. Cash flow levels may fluctuate throughout the year, and thorough financial forecasting enables you to anticipate these fluctuations. With this knowledge, you can plan for situations where extra working capital may be needed, such as taking advantage of supplier discounts, meeting vendor invoices, covering taxes and employee salaries during downturns, or acquiring another business.

4. Profit Margins

Profit margins serve as a fundamental metric for assessing a small business's profitability. The higher your profit margin, the greater flexibility you'll enjoy. However, it's essential to strike a balance between profit margin, product/service quality, and other company values, such as sustainability and community investment.

Types of Profit Margin Calculations:

There are three distinct types of profit margins, each offering unique insights:

  • Net Profit Margin: This measures profitability concerning your expenses.

  • Gross Profit Margin: Evaluates pricing strategies, production processes, and manufacturing efforts.

  • Operating Profit Margin: Provides a view of your business's day-to-day profitability, excluding taxes and interest expenses (similar to EBITDA, covered later).

How to Calculate Profit Margins:

Each profit margin type has its corresponding formula:

  • **Net Profit Margin = (Net Profit / Net Revenue) x 100

  • **Gross Profit Margin = (Gross Profit / Total Revenue) x 100

  • **Operating Profit Margin = (Operating Income / Net Sales) x 100

Effective Use of Profit Margin Calculations:

Regularly monitoring your profit margins acts as a guiding star for other financial decisions. Profit margins can forecast vital financial concepts, such as working capital. Continuous assessment of net profit margin, gross profit margin, and operating profit margin helps you stay ahead of potential issues, especially considering factors like supply chain disruptions.

5. Cost of Goods Sold (COGS)

Cost of Goods Sold (COGS) comprises expenses directly related to the sale of products, encompassing inventory, packaging, labor production costs, and raw materials. COGS is a fundamental cost calculation that aids in determining other critical business metrics, such as gross profit.

Included in COGS:

The specific elements in your COGS calculation depend on your business and its products. Common examples include shipping, direct labor, raw materials, distribution costs, finished products for resale, items required to complete a product, and materials necessary for selling a product.

Calculating COGS:

COGS can be calculated using the following formula:

COGS = (Beginning Inventory + Purchases) – Ending Inventory

  • Beginning Inventory: The value of your inventory at the start of the accounting year.

  • Purchases: Spending related to buying or producing goods during the same period.

  • Ending Inventory: The value of your inventory at the end of the accounting year.

6. Revenue

Revenue, often termed gross sales, represents the total income generated by a business. Positioned at the top of the profit and loss (P&L) sheet, revenue is sometimes referred to as the “top line.” It signifies your business's earnings without considering expenses.

Why Revenue Matters:

Revenue highlights your business's capacity to generate sales, a fundamental aspect of profitability. While profitability is the ultimate goal, businesses must first generate revenue to achieve it. Revenue also indicates market demand.

7. Valuation (Business Value)

Valuation refers to the estimation of an entity's worth. For small business owners, valuation typically pertains to their company's value, often determined using specific formulas. Understanding your business's valuation is valuable when seeking investors or selling your business. It can also serve as motivation during challenging times.

Business Valuation Methods:

Several methods gauge a business's value, including:

  • Historical Earnings Valuation: Based on revenue, debt repayment ability, and cash flow.

  • Relative Valuation: Compares your business's value to that of similar enterprises.

  • Asset Valuation: Totals tangible and intangible asset values to assess worth.

  • Future Maintainable Earnings Valuation: Uses future profitability estimates derived from past three years' revenue, profits, and expenses.

  • Discount Cash Flow Valuation: Applicable when future profits are expected to be unstable.

8. Fiscal/Accounting Year

A fiscal or accounting year deviates from the calendar year and typically spans 12 months or 52/53 weeks. It is defined by the year in which it concludes rather than when it starts. Government entities, such as the US government, establish fiscal year dates that businesses adopt for tax purposes.

9. Depreciation

Depreciation is the process through which an asset's value decreases over a specific period, often due to wear and tear. Small businesses utilize depreciation to allocate a particular value to the use of an asset relative to the revenue it generates. Depreciation serves various purposes, including tax and accounting considerations, and offers valuable insights into an asset's life expectancy.

Why Businesses Use Depreciation:

Depreciation is commonly applied to costly assets like machinery and equipment, especially in manufacturing-related purchases. It allows companies to spread the equipment's cost over time, rather than recognizing the entire cost in a single year.

Types of Depreciation:

There are different methods for calculating depreciation:

  • Straight-Line: This method allocates an equal amount of depreciation annually over an asset's useful life until it reaches its salvage value (the amount it can be sold for as parts when no longer in use).

  • Declining Balance: This method uses a percentage, typically based on the straight-line depreciation rate, to account for the fact that assets lose more value as they age.

  • Double-Declining Balance (DDB): The DDB method doubles the straight-line depreciation rate.

10. Amortization

Amortization involves the gradual repayment of a debt through scheduled principal and interest payments over time. In business, it also refers to an accounting approach that spreads out and records a debt over time, avoiding a single lump-sum entry when the debt is incurred.

11. Earnings Before Interest, Tax, Depreciation, and Amortization (EBITDA)

EBITDA is a widely used metric for assessing a startup's profitability, standing for Earnings Before Interest, Tax, Depreciation, and Amortization. It simplifies financial analysis by calculating revenue minus operating expenses.

How to Calculate EBITDA:

EBITDA = Net Income + Taxes + Interest Expense + Depreciation + Amortization

EBITDA offers insights into what a business can achieve, focusing on its potential profitability. It's particularly relevant for startups seeking investors or those owned by venture capital (VC) firms.

EBITDA —Related Terms and Calculations:

  • EBITDA Margin: Expresses a company's profitability as a percentage of revenue (EBITDA Margin = EBITDA / Revenue).

  • Adjusted EBITDA: Accounts for specific anomalies within a business, facilitating industry comparisons (Adjusted EBITDA = EBITDA +/- Adjustments).

  • EBIT: Represents core operational profits without interest and tax costs (EBIT = Net Income + Interest + Taxes).

  • EBITDA —to-Interest Coverage Ratio: Assesses a company's ability to meet its debt obligations (EBITDA —to-Interest Coverage Ratio = EBITDA / Total Interest Payments).

  • EBITDA Multiple: Measures a company's return on investment (EBITDA Multiple = Enterprise Value / EBITDA).

12. Customer Acquisition Cost (CAC)

Customer Acquisition Cost (CAC) pertains to the financial resources a business allocates to acquire a new customer. CAC encompasses expenses related to sales and marketing efforts, along with necessary equipment and assets required for customer conversion.

What's Included in CAC:

  • Direct advertising expenses (ad spend)

  • Creative costs

  • Production expenses

  • Inventory costs

  • Marketing team salaries

  • Sales team salaries

A Simple CAC Formula:

CAC = (Cost of Sales + Cost of Marketing) / Number of Customers Acquired

13. Customer Lifetime Value (LTV)

Customer Lifetime Value (LTV) quantifies a customer's total value over their entire relationship with a brand. It measures the cumulative impact of repeat business versus a one-time transaction. A high LTV indicates a profitable, long-term customer relationship, which is advantageous for businesses.

How to Calculate Customer Lifetime Value (LTV):

LTV = Average Order Total x Average Number of Purchases in a Year x Average Retention in Years

Why Customer Lifetime Value Matters for Entrepreneurs:

LTV is particularly important for subscription-based businesses and offers a way to assess the value of long-term customer relationships. It also helps evaluate the return on investment from customer acquisition costs (CAC), highlighting the significance of a sustainable customer base and the potential for profitability over time.

14. Unit Economics

Unit economics assess a business's revenue and expenses concerning an individual product or “unit of production.” To calculate unit economics, it's essential to define what constitutes a “unit” in your business context. For most businesses, a unit represents a single customer. To determine unit economics, you evaluate the cost of acquiring a unit (customer) and the value that unit generates for the business. In essence, it's about comparing Customer Lifetime Value (LTV) to Customer Acquisition Cost (CAC).

Unit Profitability Formula:

Unit Profitability = Customer Lifetime Value — Customer Acquisition Cost

Why Unit Economics Matter for Entrepreneurs:

Unit economics provide insights into how efficiently your business's spending on customer acquisition translates into value. Ideally, you want to maximize LTV while minimizing CAC. Analyzing unit economics helps identify challenges and opportunities, offering actionable insights by comparing CAC and LTV.

15. Debt-to-Equity Ratio (D/E)

The debt-to-equity ratio, also known as the risk ratio, gearing, or leverage, is a financial calculation that compares a company's liabilities to its shareholder's equity. It indicates the extent to which a business finances its operations through debt relative to equity.

How to Calculate Debt Equity Ratio:

Debt-to-Equity Ratio = (Short Term Debt + Long Term Debt + Other Fixed Payments) / Shareholder's Equity

When a Debt Equity Ratio Matters for an Entrepreneur:

Entrepreneurs typically need to consider the debt-to-equity ratio when their business involves external investors or external debt. The D/E ratio offers insights into the level of risk associated with the funding sources for a business's operations.

16. Business Credit

Similar to individuals having credit scores, businesses also have credit scores that significantly impact their ability to qualify for financing. Business credit scores range from one to 100 and serve as a crucial metric for lenders to assess a business's creditworthiness, indicating the likelihood of loan repayment. A strong business credit score broadens loan options and enables access to lower interest rates.

Factors Affecting Your Business Credit Score:

Key factors that influence your business credit score, as per Experian, include:

  • The number of years your company has been in business.

  • Lines of credit used within the past 9 months.

  • Recently opened lines of credit.

  • Liens and collections from the past 7 years.

  • One-time payment history.

How to Establish Business Credit:

To establish business credit, your business must first become a legally recognized entity. Once that's done, you can work on building a credit history. Business credit cards are a popular and flexible way to begin establishing credit. Like personal credit cards, paying off your business credit card balance in full each month helps build good credit. You can also develop credit history by working with credit lines from vendors, suppliers, and retailers.

Financial Concepts FAQs

1. What are the most common financial mistakes made by small business owners?

The most common mistakes by small business owners include prioritizing revenue over profitability and investing excessively in product development or overspending on marketing.
