What it means
A company is solvent when the value of what it owns, plus the profit it can reliably generate, is enough to cover its debts as they fall due. Insolvency comes in two forms: balance sheet insolvency, where liabilities exceed assets, and cash flow insolvency, where a business simply cannot pay on time regardless of what the balance sheet shows.
Directors have legal duties tied to solvency in most jurisdictions, and continuing to trade while insolvent can create personal liability for them. Lenders also write solvency tests into loan agreements, so breaching one can turn a comfortable long-term loan into a debt repayable on demand.
The usual measures are the debt to equity ratio, the interest coverage ratio, which is operating profit divided by interest expense, and the solvency ratio, which compares after-tax profit plus depreciation against total liabilities. None of them is decisive on its own, so analysts read them together and always against the norms of the industry.
Capital-intensive industries such as utilities and infrastructure carry far more debt than software companies and are still considered sound, because their cash flows are predictable and long-dated. The right question is therefore not how much debt exists but how reliably the cash covers interest and repayments.
A profitable business can still fail, which is the point people most often miss. If customers pay in 90 days while suppliers demand payment in 30, the accounts can show a healthy surplus while the bank balance runs dry, which is why solvency and liquidity are monitored side by side rather than one instead of the other.
In practice
Real-world examples.
Example
A regional airline reports positive profit but has $220,000,000 of aircraft lease obligations against $60,000,000 of equity. Its lenders focus on the debt to equity ratio rather than the profit figure, and a covenant limits any further borrowing until equity is rebuilt.
Example
A family-owned printer turns down a $2,000,000 machine purchase funded entirely by debt after modelling that interest cover would fall from 5.0 times to 1.8 times. The board takes a smaller, part-funded machine instead and keeps headroom for a downturn.
Example
An auditor questions whether a construction firm remains a going concern after noting that its largest loan matures in eight months with no refinancing agreed. The directors secure a written facility extension before the accounts are signed, and the qualification is avoided.
Formula
Calculation
Solvency ratio = (net profit after tax + depreciation and amortisation) / total liabilities
Debt to equity ratio = total liabilities / shareholders' equity
Interest coverage ratio = operating profit (EBIT) / interest expense
A packaging manufacturer reports the following for the year.
Net profit after tax = $1,800,000
Depreciation and amortisation = $700,000
Total liabilities = $10,000,000
Shareholders' equity = $8,000,000
Operating profit (EBIT) = $3,200,000
Interest expense = $800,000
Solvency ratio = ($1,800,000 + $700,000) / $10,000,000 = $2,500,000 / $10,000,000 = 25%
Debt to equity = $10,000,000 / $8,000,000 = 1.25
Interest coverage = $3,200,000 / $800,000 = 4.0 times
Total assets = $10,000,000 + $8,000,000 = $18,000,000, so liabilities fund 55.6% of the asset base
A solvency ratio above 20% is generally read as comfortable, and interest cover of 4.0 times means operating profit could fall by three quarters before interest became unaffordable.
Now assume a bad year halves net profit to $900,000 while depreciation and liabilities stay the same. The solvency ratio falls to ($900,000 + $700,000) / $10,000,000 = 16%, and if EBIT drops to $1,600,000 the interest cover halves to 2.0 times. Nothing has changed on the liability side, yet the business has moved from comfortable to watchful in a single year.Case study
Seen in the real world.
Ambervale Ceramics is an illustrative, fictional tile manufacturer with $14,000,000 of revenue and a long record of modest profit. It borrowed $6,000,000 to build a second kiln on the strength of a five-year supply agreement with a large retail chain, taking total liabilities to $11,000,000 against equity of $5,500,000 and a debt to equity ratio of 2.0.
Two years later the retail chain restructured and cut its order volume by half. Ambervale remained profitable at the operating line, but interest cover fell from 4.5 times to 1.6 times and the loan agreement carried a covenant requiring at least 2.0 times. The breach gave the bank the right to demand repayment, and although the company had never missed a payment it suddenly had no negotiating position at all.
The directors sold a freehold warehouse and leased it back, using the proceeds to repay $2,500,000 of the loan and restore cover above the covenant level. This fictional case shows how solvency problems typically arrive: not through reckless borrowing, but through debt sized for a level of trading that later turns out to have depended on a single customer.
Watch out
Common mistakes.
- Confusing solvency with liquidity. A business can be solvent on paper and still fail because it cannot pay a supplier this week, and it can be temporarily cash-rich while quietly insolvent on the balance sheet.
- Comparing debt to equity ratios across different industries. A utility at 2.0 may be perfectly sound while a consultancy at 2.0 is alarming, because the reliability of the cash flow differs completely.
- Ignoring off-balance-sheet and contingent obligations. Operating leases, guarantees and pending legal claims all affect real solvency even where accounting rules keep some of them out of headline liabilities.
Questions
People also ask.
What is the difference between insolvency and bankruptcy?
Insolvency is a financial condition, whereas bankruptcy or administration is the formal legal process that may follow if the condition is not resolved.
What is a good solvency ratio?
Above 20% is often treated as sound, though the benchmark varies widely by sector and matters far less than the trend across several years.
Can a company be insolvent and still trade?
Only carefully and usually only briefly, because directors in most jurisdictions must act in creditors' interests once insolvency is likely and can be personally liable for continuing to trade regardless.
