Financial Statement Analysis

Credit Ratio Analysis: Liquidity, Leverage and Coverage

Credit ratio analysis measures a borrower's ability to meet obligations. Liquidity ratios such as the current and quick ratio test short-term resources. Leverage ratios such as debt to EBITDA measure indebtedness relative to earnings. Coverage ratios such as interest coverage and fixed charge coverage test cash flow against payments. Profitability ratios show the earnings that support all three.

Why do lenders rely on financial ratios?

Ratios compress financial statements into measures that can be compared across time, across borrowers and against policy thresholds. A lender reviewing hundreds of credits needs a consistent way to see whether a borrower can meet near-term obligations, how much debt it carries relative to its earnings, and how comfortably its cash flow covers interest and principal. Ratios also form the basis of financial covenants, so they connect underwriting analysis directly to the ongoing monitoring of a loan after it closes.

Ratios are only as good as the numbers and definitions behind them. EBITDA may be reported, adjusted or covenant-defined. Debt may include or exclude leases, letters of credit and earnouts. Current assets may contain receivables that are uncollectible or inventory that is obsolete. Before interpreting any ratio, an underwriter should confirm the definitions, normalize the inputs and calculate trends over several periods. A single ratio at a single date reveals little; direction and volatility over time reveal far more. Peer comparisons add further context, provided peers use similar definitions.

Which liquidity ratios matter?

The current ratio divides current assets by current liabilities and measures whether short-term resources cover short-term obligations. The quick ratio excludes inventory and prepaid items, which may be slow to convert into cash, and uses only cash, marketable securities and receivables. Liquidity ratios are particularly important for working capital lenders and for businesses with seasonal cash swings, where a strong year-end position may mask a mid-year cash trough that requires revolver support. Monthly calculations, rather than only year-end figures, reveal these swings.

Interpreting liquidity requires context. A retailer that collects cash at the point of sale and pays suppliers on terms can operate safely with a current ratio below one. A contractor with large retainage receivables may show a high ratio yet be short of cash. Underwriters should complement balance sheet ratios with a cash flow view: months of fixed costs covered by cash and available revolver capacity, and the size of the seasonal peak borrowing need relative to committed facilities. That combination gives a far more reliable view of near-term liquidity than any single balance sheet ratio.

How is leverage measured?

Leverage ratios compare debt with earnings or with capital. Total debt to EBITDA estimates how many years of earnings, before interest, taxes and noncash charges, would be required to repay all debt. Net debt to EBITDA subtracts unrestricted cash. Senior debt to EBITDA isolates the leverage in the senior tranche, which matters for pricing and recovery. Balance sheet leverage ratios, such as debt to capitalization or debt to tangible net worth, compare debt with the equity cushion beneath it. Each measure answers a slightly different question about risk.

Earnings-based leverage depends heavily on the EBITDA definition. Covenant EBITDA with generous add-backs produces lower ratios than diligence-adjusted EBITDA. Lease treatment also affects comparability. Underwriters should compute leverage on their own consistent basis, compare it with the covenant calculation, and track how it would change in a downside case. Leverage that looks acceptable at peak earnings may become excessive after a moderate decline in EBITDA, which is why trend and sensitivity analysis matter as much as the point estimate. A simple table showing leverage at several EBITDA levels makes that sensitivity clear to a credit committee.

What do coverage ratios tell you?

Coverage ratios measure whether cash flow is sufficient to meet required payments. Interest coverage, EBITDA divided by interest expense, shows the cushion over interest alone. Fixed charge coverage is more demanding: it typically subtracts unfinanced capital expenditures, cash taxes and sometimes distributions from EBITDA, and divides by interest plus scheduled principal, and often rent. Debt service coverage, common in real estate and small business lending, compares cash flow available for debt service with total annual debt service. Each lender and program defines these ratios slightly differently, so the formula used should always be stated.

Coverage ratios capture what leverage ratios miss: the actual cash burden of the debt. Two borrowers with the same leverage may have very different coverage because of interest rates, amortization schedules or capital intensity. Floating-rate borrowers should be tested at higher base rates. Coverage below one means the business cannot meet its obligations from operations and must rely on cash reserves, asset sales or new capital, which is a critical warning sign for any lender. Coverage trends often deteriorate before leverage covenants are breached, which makes them a useful early warning indicator in portfolio monitoring.

How do profitability ratios fit into credit analysis?

Profitability ratios, such as gross margin, EBITDA margin, operating margin and return on assets, show the earnings capacity that supports debt service. For credit purposes, stability matters more than level. A business with modest but steady margins may be a better credit than one with high but volatile margins. Margin trends also explain changes in leverage and coverage, since rising leverage is often the result of falling margins rather than new borrowing. Breaking margins into price, volume and cost effects helps reveal the cause. Gross margin by product line or customer segment often explains more than the consolidated figure.

Return on invested capital compares operating profit after tax with the capital employed in the business. A business earning returns well above its cost of capital can typically sustain or grow its cash flow, while one earning below its cost of capital may be destroying value even if it services its debt today. Combining profitability with leverage and coverage gives a complete picture: how much the business earns, how much it owes and how easily it can pay. Lenders should also watch for profitability supported by one-time gains, which inflate ratios without improving repayment capacity.

Calculating a credit ratio dashboard

1. Balance sheet: current assets $6.0 million, of which cash $1.0 million and receivables $2.5 million; current liabilities $4.0 million; total debt $18.0 million.
2. Current ratio = 6.0 / 4.0 = 1.50x. Quick ratio = (1.0 + 2.5) / 4.0 = 0.88x.
3. Income statement: revenue $40.0 million, EBITDA $5.0 million, interest $1.2 million. EBITDA margin = 5.0 / 40.0 = 12.5%.
4. Total leverage = 18.0 / 5.0 = 3.60x. Net leverage = (18.0 - 1.0) / 5.0 = 3.40x. Interest coverage = 5.0 / 1.2 = 4.17x.
5. Fixed charges: unfinanced capex $0.8 million, cash taxes $0.4 million, scheduled principal $1.5 million. FCCR = (5.0 - 0.8 - 0.4) / (1.2 + 1.5) = 3.8 / 2.7 = 1.41x.
6. Downside: if EBITDA falls 20% to $4.0 million, leverage = 18.0 / 4.0 = 4.50x and FCCR = (4.0 - 0.8 - 0.4) / 2.7 = 2.8 / 2.7 = 1.04x.

How underwriters apply this

• Confirm every ratio's definition and calculate it on a consistent, diligence-adjusted basis before comparing with policy or covenants.
• Analyze trends and volatility over several periods rather than a single date.
• Pair leverage with coverage, since the same leverage can carry very different cash burdens.
• Stress ratios for lower EBITDA and higher rates to find the headroom before covenant breach.
• Supplement balance sheet liquidity ratios with a cash runway and seasonal peak analysis.
