Business Debt Ratio: What It Is and How to Improve It

Debt ratios measure how leveraged your business is.

The Main Leverage Ratios and What Each One Shows

Debt ratio = Total liabilities ÷ Total assets. The simplest measure of how much of the business is funded by debt rather than by owners. Below 0.5 is conservative, 0.5 to 0.6 is typical, above 0.7 is heavily leveraged and limits further borrowing.

Debt-to-equity ratio = Total liabilities ÷ Total equity. Compares what creditors have at risk to what owners have at risk. Lenders generally prefer below 2.0 for small businesses, and below 1.0 signals a strongly capitalised business.

Debt Service Coverage Ratio (DSCR) = Net operating income ÷ Total annual debt service. The most important ratio in lending decisions. Most lenders require 1.25 or higher. This measures whether the business can actually pay what it owes, whereas the debt ratio measures how much it owes.

Interest coverage ratio = Operating profit ÷ Interest expense. Shows how many times over the business could pay its interest from operating profit. Below 2.0 is a warning sign; below 1.0 means the business is not earning enough to cover its interest.

The reason a lender looks at all of them: a business can have a moderate debt ratio and a poor DSCR if it has borrowed heavily against a large asset that generates little income. Conversely, a business with high leverage and strong DSCR is a reasonable risk. Coverage matters more than leverage, but both are reviewed.

Why Lenders Care and What Thresholds They Use

Underwriting is fundamentally about the probability of repayment, and leverage is the best single predictor of how badly a business will react to a downturn. A business with no debt can survive a 40% revenue drop. A business with debt equal to 80% of assets may not survive a 15% drop, because the debt service is fixed regardless of revenue.

Traditional banks typically want a debt ratio below 0.6, a DSCR above 1.25, and often a personal guarantee alongside. They may also require you to maintain these ratios as covenants in the loan agreement.

SBA lenders apply similar standards, with the SBA's own credit criteria layered on top. A DSCR below 1.15 is generally difficult to approve without compensating factors such as strong collateral or a co-signer.

Online lenders are more flexible on leverage and more focused on cash flow through your bank statements. Rates are correspondingly higher because weaker balance sheets are priced in.

Equipment financiers care less about the overall debt ratio because the specific asset secures the loan. They focus on the asset's value and resale market instead.

Watch for covenants in any loan agreement. A covenant might require you to maintain a debt ratio below a specified level. Breaching it can technically constitute default even if you have never missed a payment, which is why owners need to monitor the ratio monthly rather than annually.

Improving the Ratio: The Four Routes

There are only four ways to improve a leverage ratio, and they have very different timescales.

Increase profit and retain it. The healthiest route and the slowest. Every dollar of retained earnings increases equity and reduces the ratio, while also increasing assets. A business retaining $60,000 a year on $500,000 of assets improves its ratio by roughly two to three percentage points annually.

Pay down debt. Effective and fast if you have surplus cash, provided there is no prepayment penalty. Prioritise the highest-rate debt first, since that also reduces your interest cost.

Convert debt to equity. If you have a related-party loan from the owner, converting it to equity improves the ratio immediately with no cash needed. This is a common and often overlooked step before a loan application.

Increase assets without debt. Retain profit, collect receivables, reduce inventory, or sell surplus assets. Reducing inventory is often the fastest available improvement, because slow stock is both an asset underperformer and a cash absorber.

Note that all four routes assume you want the ratio lower. Sometimes a temporarily high ratio is correct — a business that has just financed a large revenue-generating asset may look leveraged on the day of purchase and be well positioned a year later. Lenders understand this, which is why DSCR carries more weight than the debt ratio for asset purchases.

Industry Variation and Why It Matters

A debt ratio that is healthy in one industry is alarming in another. Capital-intensive businesses carry structurally more debt because they must finance plant and equipment.

Manufacturing, transport, agriculture and property businesses commonly run debt ratios of 0.5 to 0.65. Service businesses, software companies and consultancies typically run below 0.4 because they need little in the way of fixed assets.

This means comparing your ratio against a general benchmark is misleading. Compare against your own trend, and against businesses of a similar asset intensity. A software company at 0.6 is heavily leveraged; a haulage company at 0.6 is normal.

The ratio also interacts with asset quality. A debt ratio of 0.55 looks different depending on what the assets are. If they are modern equipment with a liquid resale market, the lender has recovery options. If they are specialised inventory with no secondary market or goodwill that would vanish in a liquidation, the same ratio represents far more risk.

Worked Example: A Refinancing That Failed Until the Ratio Was Fixed

A commercial printing business applies to refinance $340,000 of equipment loans at a lower rate. The owner expects easy approval because the business has never missed a payment and revenue is stable at $1.6 million.

The balance sheet shows total assets of $720,000 — $40,000 cash, $180,000 receivables, $90,000 inventory, and $410,000 of equipment. Total liabilities are $520,000, and equity is $200,000.

The debt ratio is 520,000 ÷ 720,000 = 0.72. The debt-to-equity ratio is 2.6. Both are above the lender's thresholds of 0.6 and 2.0.

Net operating income is $168,000 and total annual debt service is $112,000, so DSCR is 1.50 — comfortably above the 1.25 minimum. The business can afford its debt; it is simply carrying too much of it relative to its assets.

The lender indicates the refinancing could proceed at a smaller amount but not at the full $340,000. The owner needs to improve the ratio before reapplying.

Three actions. First, the owner holds a $45,000 related-party loan he made to the business in year one, and converts it to equity. Liabilities fall to $475,000 and equity rises to $245,000. The debt ratio moves to 0.66 and debt-to-equity to 1.94.

Second, inventory is reduced from $90,000 to $62,000 by selling slow-moving paper stock at cost, using the cash to pay down the highest-rate loan. Assets fall to $692,000 and liabilities to $447,000. Debt ratio is now 0.646.

Third, the business delays a $30,000 planned equipment purchase until after the refinancing, avoiding new debt.

Reapplying with a debt ratio of 0.646, debt-to-equity of 1.82, and DSCR of 1.63, the refinancing is approved at the full $340,000 at a rate two percentage points lower, saving roughly $6,800 a year in interest.

Nothing about the business's profitability changed. The ratio improved through balance sheet management, and the cost of borrowing fell as a result.

Leverage Ratios and Their Thresholds

Risks and Points of Caution

• Loan covenants tied to ratios. A covenant requiring a debt ratio below a set level can be breached by taking on a new lease or a bad quarter. Breach can technically trigger default despite perfect payment history.
• Comparing against general benchmarks. Capital-intensive industries legitimately run higher ratios. Compare with asset-similar businesses.
• Ignoring asset quality. Goodwill and specialised inventory do not recover value in a liquidation, so the same ratio represents more risk.
• Using short-term debt for long-term assets. This produces a misleadingly low debt ratio while creating severe refinancing risk at maturity.
• Improving the ratio cosmetically. Converting related-party debt to equity genuinely improves the ratio, but delaying necessary maintenance or understating liabilities does not, and will be discovered in due diligence.

Managing Your Leverage

1. Calculate your debt ratio, debt-to-equity, DSCR and interest coverage from your latest balance sheet.
2. Compare the debt ratio against your own trend, and against asset-similar businesses rather than a general figure.
3. Check whether any existing loan agreement contains covenants tied to these ratios.
4. If you have related-party loans from owners, consider converting them to equity before applying for new credit.
5. Identify slow inventory or surplus assets that can be converted to cash and used to repay the highest-rate debt.
6. Prioritise repayment of the highest-rate debt first, which improves both the ratio and your interest cost.
7. Recheck the ratios before every credit application, because lenders will calculate them.
8. Review leverage quarterly, and immediately after any large purchase or new facility.
