Financial Ratios and Capital Structure
Financial Ratios
Financial ratios help you interpret your financial statements quickly. Rather than looking at raw numbers, ratios allow you to compare your performance against industry standards, against your own historical performance, or against competitors.
Profitability Ratios
Measure how efficiently your business generates profit.
Gross Profit Margin:
Gross Profit Margin = (Gross Profit / Revenue) × 100
Example: If revenue is $1,000 and gross profit is $600, your gross profit margin is 60%. This means you keep $0.60 of every dollar of revenue after direct costs.
Net Profit Margin:
Net Profit Margin = (Net Income / Revenue) × 100
Example: If net income is $200 on $1,000 revenue, your net profit margin is 20%.
What's a good margin? It depends on your industry. Service businesses often have higher margins than product businesses because they have lower COGS.
Liquidity Ratios
Measure your ability to pay short-term obligations.
Current Ratio:
Current Ratio = Current Assets / Current Liabilities
A ratio above 1.0 means you have more assets than liabilities — you can pay your short-term debts. A ratio below 1.0 is a warning sign.
Quick Ratio (Acid Test):
Quick Ratio = (Cash + Accounts Receivable) / Current Liabilities
More conservative than the current ratio — excludes inventory because inventory takes time to convert to cash.
Solvency Ratios
Measure long-term financial stability.
Debt-to-Equity Ratio:
Debt-to-Equity = Total Debt / Owner's Equity
A high ratio means the business is heavily reliant on debt. Lower is generally better, especially for young businesses.
Why Ratios Matter
- They let you spot trends — is your profit margin improving or shrinking over time?
- They let you compare — how do you stack up against similar businesses?
- They help investors and lenders assess risk
- They help you identify problems before they become crises
Capital Structure
Capital structure refers to how your business is financed — the mix of debt (borrowed money) and equity (ownership investment).
Debt vs. Equity
Debt financing:
- You borrow money and agree to repay it with interest
- You keep full ownership of the business
- If the business fails, the lender gets paid before owners
- Examples: bank loans, lines of credit, government loans
Equity financing:
- You sell a portion of ownership in your business in exchange for investment
- You don't have to repay the money
- The investor shares in profits and losses
- Examples: selling shares, angel investors, venture capital
Choosing Between Debt and Equity
Use debt when:
- You're confident in your cash flow to make repayments
- You want to maintain full ownership
- You have collateral (assets to secure the loan)
Use equity when:
- You don't have predictable cash flow yet
- The investor brings valuable expertise or network beyond just money
- You're growing fast and need significant capital
Bootstrapping: Many early-stage entrepreneurs start by bootstrapping — funding the business entirely from personal savings and early revenues. This avoids giving up ownership and forces financial discipline. It's often the best starting point.
