Common Financial Ratios Used in Underwriting: The Complete Guide for Business Owners
When you apply for a business loan, lenders do not simply review your credit score and move on. Behind every approval decision is a structured analysis of your company's finances - and at the center of that analysis are the financial ratios used in underwriting. These ratios translate raw financial data into meaningful signals that help underwriters assess whether your business can handle new debt, repay what it borrows, and sustain operations over the long term.
Understanding these metrics puts you in a stronger position. When you know what underwriters are looking for, you can prepare your financials, address weak spots before applying, and present your business in the best possible light. This guide explains the most important financial ratios used in underwriting, what they measure, what lenders consider acceptable, and how you can improve your numbers before you submit an application.

What Is Financial Underwriting?
Underwriting is the process lenders use to evaluate the risk of extending credit to a borrower. For business loans, underwriters analyze your company's financial statements, credit history, industry, and management to determine whether lending to your business is a reasonable risk and, if so, at what terms.
Financial ratios are the quantitative backbone of this process. They condense pages of balance sheets, income statements, and cash flow statements into a handful of comparable numbers. Because ratios are standardized, a lender can quickly compare your business against industry benchmarks and against other applicants - regardless of the size of the companies being compared.
Underwriters typically look at five categories of financial ratios: liquidity, profitability, leverage, coverage, and efficiency. Each category answers a different question about your business's financial health. Together, they paint a picture of whether you are a creditworthy borrower.
Key Insight: According to the Federal Reserve's Small Business Credit Survey, about 43% of small businesses that applied for financing in a recent year were denied or received less than the full amount requested. Understanding the ratios underwriters use gives you a measurable advantage before you apply.
Liquidity Ratios: Can You Meet Short-Term Obligations?
Liquidity ratios measure your ability to pay short-term debts and obligations as they come due. A business with strong liquidity can handle unexpected expenses, slow periods, and near-term debt payments without crisis. Lenders pay close attention to these numbers because a business that cannot cover its current bills is a poor candidate for taking on more debt.
Current Ratio
The current ratio is calculated by dividing current assets by current liabilities. Current assets include cash, accounts receivable, and inventory - anything that can be converted to cash within 12 months. Current liabilities include accounts payable, short-term debt, and accrued expenses due within the same period.
A current ratio above 1.0 means the business has more short-term assets than short-term obligations. Most lenders prefer a current ratio of at least 1.5, with 2.0 or higher considered strong. A ratio below 1.0 is a warning sign - it means you owe more in the near term than you can readily pay.
Formula: Current Ratio = Current Assets / Current Liabilities
Quick Ratio (Acid-Test Ratio)
The quick ratio is a more conservative version of the current ratio. It excludes inventory from current assets because inventory is not always easy to convert to cash quickly. For businesses with large or slow-moving inventory, the quick ratio gives a sharper picture of immediate liquidity.
A quick ratio of 1.0 or higher is generally seen as healthy. Anything below 0.8 may raise concerns during underwriting.
Formula: Quick Ratio = (Cash + Accounts Receivable) / Current Liabilities
Cash Ratio
The cash ratio is the most conservative of the three, using only actual cash and cash equivalents. It answers the question: if all short-term obligations came due today, could you pay them with the cash on hand? While lenders rarely require a high cash ratio, a very low one paired with weak quick and current ratios signals potential insolvency risk.

Profitability ratios measure how effectively your business converts revenue into profit. They tell underwriters whether the business is not just surviving, but generating genuine returns. A lender needs confidence that your business earns enough to service debt while still covering operating expenses and owner compensation.
Net Profit Margin
Net profit margin expresses net income as a percentage of total revenue. It shows how many cents of profit the business keeps for every dollar of sales after all expenses - including interest and taxes - are paid.
Industry averages vary widely. A 10% net profit margin might be excellent in grocery retail but underwhelming in software. Underwriters benchmark your margin against your specific industry. A trend of improving margins is often as important as the absolute number.
Formula: Net Profit Margin = (Net Income / Revenue) x 100
Gross Profit Margin
Gross profit margin measures profitability before operating expenses, focusing on how efficiently the business produces or delivers its products and services. A declining gross margin may indicate rising input costs or pricing pressure - both signals that underwriters note.
Formula: Gross Profit Margin = ((Revenue - COGS) / Revenue) x 100
Return on Assets (ROA)
ROA measures how efficiently the business uses its assets to generate profit. A higher ROA indicates that the business is squeezing more return from its asset base - an indicator of operational quality that matters to underwriters evaluating management effectiveness.
Formula: ROA = Net Income / Total Assets
Return on Equity (ROE)
ROE shows how much profit the business generates relative to shareholders' equity. It is a measure of how well ownership capital is being deployed. High ROE relative to industry peers suggests a well-run operation, which gives lenders greater confidence.

Leverage Ratios: How Much Debt Are You Carrying?
Leverage ratios measure how much of your business is financed by debt versus equity. They tell underwriters how heavily indebted the business already is and whether it has the financial cushion to absorb additional debt without becoming over-leveraged. High leverage means higher risk - if revenues decline, a heavily indebted business may struggle to meet its obligations.
Debt-to-Equity Ratio (D/E)
The debt-to-equity ratio compares total liabilities to total shareholders' equity. A ratio of 1.0 means the business has equal amounts of debt and equity. A ratio of 3.0 means the business owes three times as much as it owns. Most conventional lenders prefer a D/E ratio under 2.5, though SBA lenders and alternative lenders may accept higher ratios in certain industries.
Formula: D/E Ratio = Total Liabilities / Total Equity
Debt-to-Asset Ratio
This ratio measures what percentage of your total assets are financed by debt. A ratio of 0.60, for example, means 60% of your assets were funded through borrowing. Lenders generally prefer this ratio to be below 0.50, meaning at least half of your asset base is equity-financed.
Formula: Debt-to-Asset Ratio = Total Debt / Total Assets
Equity Multiplier
The equity multiplier shows how much of the business's total assets are funded by equity. A higher multiplier indicates more leverage. It is often used in conjunction with ROE to break down what is driving returns - whether it is genuine operational efficiency or financial engineering through debt.
Pro Tip: If your debt-to-equity ratio is high because of a recent equipment purchase or expansion, be prepared to explain this to your lender. Context matters. Underwriters are more comfortable with leverage that funded productive, revenue-generating assets than leverage used for operating losses.
Coverage Ratios: Can You Service New Debt?
Coverage ratios are often the most scrutinized metrics in business loan underwriting. They answer the single most important question a lender has: does this business generate enough income to repay what it borrows? Unlike the other categories, coverage ratios directly relate your earnings to your debt obligations.
Debt Service Coverage Ratio (DSCR)
The DSCR is arguably the most critical single ratio in commercial lending. It compares your net operating income to your annual debt service - meaning all principal and interest payments due in a given year, including the proposed new loan.
A DSCR of 1.0 means the business earns exactly enough to cover its debt payments. A DSCR of 1.25 means the business earns 25% more than it needs - providing a buffer. Most conventional lenders and SBA lenders require a minimum DSCR of 1.25. Some lenders set the bar at 1.15 for lower-risk borrowers; others require 1.35 or higher for riskier loans.
Formula: DSCR = Net Operating Income / Total Annual Debt Service
If your DSCR falls below the lender's threshold, you will either be denied or offered a smaller loan amount. Improving your DSCR - by increasing revenue, reducing expenses, or structuring the loan with a longer term to reduce annual payments - is one of the most impactful things you can do before applying.
Interest Coverage Ratio
The interest coverage ratio focuses specifically on your ability to pay interest expense, excluding principal repayment. It divides EBIT (Earnings Before Interest and Taxes) by interest expense. A ratio below 1.5 is generally considered concerning; lenders prefer to see 2.5 or higher.
Formula: Interest Coverage Ratio = EBIT / Interest Expense
Fixed Charge Coverage Ratio (FCCR)
The FCCR is an expanded version of the DSCR that includes not just debt service but all fixed charges - rent, lease payments, insurance, and similar recurring obligations. Because it captures the full picture of your fixed cost burden, it is especially important for businesses with significant lease or equipment obligations.
Formula: FCCR = (EBIT + Fixed Charges) / (Fixed Charges + Debt Service)

Efficiency ratios measure how well the business converts its assets and liabilities into productive activity. They tell underwriters whether the business is operationally disciplined - collecting money it is owed, managing inventory thoughtfully, and making the most of its asset base. Efficiency problems can mask other issues, including cash flow shortfalls that may not be obvious from the income statement alone.
Accounts Receivable Turnover
This ratio measures how quickly the business collects payments from customers. A higher ratio means faster collection - a positive sign. Divide net credit sales by average accounts receivable to get this figure. If your turnover is significantly below industry averages, it may indicate slow-paying customers or lax collection practices - both of which can create cash flow problems.
Days Sales Outstanding (DSO)
DSO is the average number of days it takes to collect payment after a sale. A DSO of 30 means you collect within a month on average. A DSO of 75 may signal collection issues. Lenders note high DSO because it indicates that a portion of your reported revenue has not yet been converted to cash.
Formula: DSO = (Accounts Receivable / Net Credit Sales) x 365
Inventory Turnover
For product-based businesses, inventory turnover reveals how many times inventory is sold and replaced over a period. Low inventory turnover suggests slow-moving goods, potential obsolescence, or excess ordering - all of which tie up capital and increase operating risk.
Asset Turnover Ratio
Asset turnover measures how efficiently the business uses its total asset base to generate revenue. A high asset turnover ratio suggests the business is extracting strong revenue from relatively modest assets - a signal of operational efficiency that lenders view favorably.

How Crestmont Capital Evaluates Your Application
At Crestmont Capital, our underwriting process is designed to see the full picture of your business - not just the numbers on a page. We review financial ratios in context, considering your industry, stage of business, recent trends, and the purpose of the financing.
We offer a broad range of financing products that can be structured to work with a variety of financial profiles. For businesses with strong cash flow but high existing leverage, a working capital loan structured around revenue performance may be a better fit than a traditional term loan evaluated purely on balance sheet metrics. For businesses purchasing productive assets, our equipment financing programs use the asset itself as collateral, which can improve the underwriting picture even when traditional ratios are borderline.
We also work with businesses that have had credit challenges. Our SBA loan programs and business lines of credit provide flexible options for businesses at different stages of financial development. And our experienced advisors can walk you through your ratios, explain what they mean in your specific context, and help you identify the financing structure most likely to result in approval.
We are rated the number one business lender in the country - and that reputation is built on working with real business owners, understanding their real financial situations, and finding solutions that work.
Important: Lenders vary significantly in which ratios they weight most heavily and what thresholds they use. Traditional banks typically require stronger ratios across the board. Alternative lenders like Crestmont Capital often take a more holistic view, weighing cash flow trends, owner credit, business purpose, and other factors alongside the standard metrics.
How to Improve Your Financial Ratios Before Applying
If you review your ratios and find that some fall below typical thresholds, you do not necessarily need to wait years to apply. Many ratios can be meaningfully improved in a relatively short period with disciplined financial management.
Improving Your DSCR
The most impactful improvement you can make is increasing your net operating income relative to your debt payments. This can be achieved by growing revenue, cutting non-essential expenses, or restructuring existing debt to lower your annual payment obligations. Refinancing high-rate debt into lower-rate products, for example, directly reduces your annual debt service - which raises your DSCR without changing your earnings.
Improving Your Current and Quick Ratios
Pay down short-term liabilities before applying. If you have credit card balances or short-term notes, paying those down improves both your current ratio and your quick ratio. Accelerating collections - by offering early payment discounts or tightening payment terms with customers - can also boost the cash component of your current assets.
Reducing Leverage
If your debt-to-equity ratio is high, consider whether any existing debt can be paid off or restructured before your application. Increasing retained earnings - by keeping more profit in the business rather than distributing it - also raises equity and lowers the D/E ratio over time.
Cleaning Up the Books
Sometimes ratio problems are not operational but presentational. Ensuring your financial statements are clean, current, and properly categorized matters. Misclassified expenses, outdated asset valuations, or incomplete depreciation schedules can make your ratios look worse than your actual financial condition warrants. Working with a CPA to prepare or review your statements before applying is often worth the investment.
Real-World Scenarios: Financial Ratios in Action
Scenario 1: The Restaurant Operator with Strong Revenue but High Debt
A restaurant owner with $800,000 in annual revenue wants to finance a second location. Their current ratio is 1.8 - healthy. But their debt-to-equity ratio is 3.5 due to existing equipment financing and an SBA loan from their first location. Their DSCR with the proposed new loan drops to 1.1 - below the typical 1.25 threshold.
The solution: restructuring the existing SBA loan to a longer term reduced the annual payment, raising the DSCR to 1.28. With that adjustment, the application was approved.
Scenario 2: The Manufacturer with Excellent Margins but Poor Liquidity
A manufacturer has a 22% net profit margin - outstanding by industry standards. However, their current ratio is only 0.9 because they have a large short-term note payable that will renew later in the year. Their quick ratio is even lower at 0.65 because a significant portion of their assets are tied up in raw materials inventory.
Underwriters saw the strong profit margin as a positive offset. The solution was structuring the loan with a 6-month interest-only period, allowing the manufacturer to build cash reserves and address the short-term note before full payments began.
Scenario 3: The Service Company with Perfect Ratios
A staffing company has a current ratio of 2.1, a DSCR of 1.6, a net profit margin of 18%, and a debt-to-equity ratio of 0.8. Their financials are excellent by any measure. They qualify for a large term loan at highly competitive rates with minimal documentation requirements beyond standard financials - an example of how strong ratios directly translate into better financing terms.
Scenario 4: The Startup with Limited History
A business opened 18 months ago and has strong revenue growth but limited financial history. Traditional lenders struggle to calculate reliable ratios with only one full tax return available. In this case, a revenue-based financing product structured around monthly cash flow - rather than traditional balance sheet ratios - provided the capital the business needed to continue growing.
Scenario 5: The Seasonal Business with Fluctuating Ratios
A landscaping company shows strong ratios in their fiscal year-end statements taken in October (peak season) but much weaker ratios in March (off-season). Sophisticated underwriters look at trailing 12-month averages and month-by-month cash flow rather than a single year-end snapshot to get an accurate picture of businesses with seasonal revenue patterns.

Understanding the financial ratios used in underwriting is one of the most practical steps any business owner can take before applying for a loan. When you know what underwriters are looking at, you can work proactively to present your business in the strongest possible light - or identify gaps that need addressing before submitting an application.
Liquidity ratios confirm you can meet near-term obligations. Profitability ratios show your business generates real returns. Leverage ratios reveal how much of your balance sheet is debt-financed. Coverage ratios - especially the DSCR - demonstrate that you earn enough to repay what you borrow. And efficiency ratios confirm that your operational management is sound.
No single ratio tells the whole story, and most lenders evaluate the complete picture rather than disqualifying borrowers based on one metric. If your ratios are not where they need to be today, the good news is that most can be improved with deliberate action over a matter of months. Crestmont Capital's team is here to help you navigate the process and find the financing solution that works for your specific situation.
