Financial ratios have long been essential for evaluating a company’s financial and operational health. These ratios offer a precise yet comprehensive view, helping stakeholders make informed decisions. For lenders, especially those involved in commercial loan underwriting, understanding these ratios is critical to assessing a borrower’s creditworthiness.
Most ratios can be derived from financial statements and compared against industry benchmarks for a broader perspective. However, interpreting the results is far more significant for bankers than the computation itself. Solvency and performance validation remain the two key objectives of ratio analysis, and choosing the right ones can greatly influence lending decisions.
In this blog, we delve into five crucial financial ratios used in commercial loan underwriting, their importance, and how they are applied in real-world scenarios.

An In-debt Guide: 5 Key Ratios
1. Profit Margin Ratio:
The profit margin ratio is one of the most fundamental profitability ratios, reflecting how much profit a company generates for every dollar of sales. It indicates the company’s ability to sustain and reinvest in growth opportunities.
Example: A company with a profit margin of 20% retains $0.20 of profit for every dollar earned. Industries like technology might see higher margins, whereas manufacturing often operates on thinner margins. Bankers should always compare a company’s profit margins to industry peers and historical data to detect trends or abnormalities.
Additionally, profit margin analysis helps lenders identify operational inefficiencies that may impact long-term sustainability. For instance, low margins could indicate rising costs, inefficient processes, or increased competition.
2. Debt Ratio:
The debt ratio measures the proportion of a company’s assets financed through debt. This solvency ratio is a direct indicator of financial leverage and business stability. A lower debt ratio, typically below 0.5, suggests a more financially stable business with twice the assets compared to liabilities. Conversely, a ratio higher than 0.5 warrants a closer examination.
Example: If a company has a debt ratio of 0.8, it means 80% of its assets are financed through debt, which could pose significant risks during economic downturns or interest rate hikes. Lenders often rely on this metric to determine if a borrower can sustain additional loans without jeopardizing their financial structure.
Bankers should also consider the industry context. In capital-intensive sectors like real estate or infrastructure, higher debt ratios might be standard, but they still demand careful evaluation.
3. Loan-to-Value (LTV) Ratio:
The loan-to-value (LTV) ratio is pivotal in assessing the risk associated with secured loans, particularly mortgages. It compares the loan amount to the appraised value of the collateral. A lower LTV ratio indicates that the collateral’s value exceeds the loan amount, providing a safety net for the lender in case of default.
Example: If a borrower seeks a $100,000 loan against a property valued at $125,000, the LTV ratio would be 80%. This is generally considered acceptable, whereas an LTV ratio above 90% might indicate higher risk.
Lenders often set maximum LTV thresholds depending on the type of collateral and the loan product. Regularly monitoring LTV ratios ensures that loans remain secure and minimizes the risk of collateral devaluation impacting recovery.
4. Debt Service Coverage Ratio (DSCR):
The DSCR evaluates a business’s ability to generate enough cash flow to cover its debt obligations, including principal, interest, and leases. A DSCR of 1.25-1.5 is often deemed safe, indicating the borrower earns $1.25 to $1.50 for every dollar of debt payment.
Example: A DSCR of 1.2 means the borrower has 20% more cash flow than required to meet debt obligations. However, ratios below 1 signal insufficient cash flow, which is a red flag for lenders.
Bankers should consider the borrower’s business model and cash flow cycles when analyzing DSCR. Seasonal businesses, for example, might exhibit fluctuations in DSCR depending on their revenue patterns.
5. Net Worth-to-Loan Size Ratio:
This ratio compares a borrower’s net worth to the size of the requested loan. A high net worth-to-loan size ratio signals financial stability and assures lenders of the borrower’s ability to repay the loan, even under challenging circumstances.
Example: If a borrower with a net worth of $5 million applies for a $1 million loan, the ratio would be 5:1, which reflects a strong financial position. On the other hand, a ratio close to 1:1 might indicate over-leveraging and necessitates further scrutiny.
This metric is particularly useful for evaluating the financial health of SMEs and family-run businesses where personal net worth often intertwines with business finances.
The Importance of Peer Comparison
Financial ratios vary significantly across industries, making peer comparison a crucial step in the analysis. Comparing ratios within the same sector helps lenders understand the borrower’s competitive positioning and operational efficiency. For instance, profit margins in the retail sector are inherently lower than those in software development, and applying a generic benchmark could lead to inaccurate conclusions.
