What it means
The logic behind the ratio is that profit alone understates the cash a business throws off, because depreciation is a bookkeeping charge that never leaves the bank account. Adding depreciation back gives a rough measure of annual cash generation, which is then set against everything the business owes to outsiders.
Total liabilities means all of them, short term and long term: overdrafts, trade creditors, tax owed, leases and bank loans. Using total liabilities rather than just borrowings makes the ratio a stricter test than gearing measures that count only interest bearing debt.
Interpretation depends heavily on the industry, though a figure above 20% is often treated as comfortable and anything below 10% as a signal to look harder. A ratio of 25% roughly implies that four years of current cash generation would clear the entire debt load if nothing else changed.
Lenders like the measure because it links the balance sheet to real cash rather than to accounting profit alone. Credit teams often track it over three to five years, since the direction of travel says more than a single year's number, particularly for a business investing heavily in new assets.
The main nuance is that the name is used loosely. Some analysts use solvency ratio to mean total assets divided by total liabilities, insurers use a regulatory version comparing capital held against capital required, and textbooks sometimes use it as a general label for the whole family of long term ratios, so always confirm the definition before comparing figures.
In practice
Real-world examples.
Example
A bank compares two haulage companies applying for the same facility. Both report similar profits, but one has a solvency ratio of 24% against the other's 9%, and the difference in debt levels decides which application succeeds.
Example
A manufacturer's solvency ratio falls from 22% to 13% in the year it finances a new production hall. The finance director explains to the board that the fall is expected, since the debt arrives immediately while the extra output only starts to earn from the following year.
Example
A software firm with almost no fixed assets records a solvency ratio of 48%, because it carries little debt and depreciation is small. Its board uses the headroom to fund an acquisition with borrowing rather than issuing new shares.
Think of it
“Solvency ratios assess whether a company can survive long-term-not just pay this month's bills.
Formula
Calculation
Solvency ratio = ((net profit after tax + depreciation) / total liabilities) x 100
A commercial printing business reports net profit after tax of $1,050,000 and a depreciation charge of $450,000 for the year, so annual cash generation is $1,050,000 + $450,000 = $1,500,000.
Its balance sheet shows short term liabilities of $2,000,000 and long term liabilities of $5,500,000, giving total liabilities of $2,000,000 + $5,500,000 = $7,500,000.
Solvency ratio = ($1,500,000 / $7,500,000) x 100 = 20%. On that basis the business generates enough cash each year to cover a fifth of everything it owes, implying a repayment period of about five years at the current rate.Case study
Seen in the real world.
The following is a fictional, illustrative example. Cartwell Joinery, an invented family owned manufacturer, had been trading for thirty years and measured success purely by the profit figure at the bottom of its annual accounts. Profit had been positive in every year but two.
When the family approached a bank for a $2.5 million expansion loan, the credit team calculated a solvency ratio of 7%. Net profit of $180,000 plus depreciation of $240,000 gave $420,000 of annual cash generation against $6,000,000 of total liabilities, much of it trade creditors that had been stretched to fund working capital. The illustrative point is that a thirty year record of profit had disguised a balance sheet that would need more than fourteen years of current cash generation to clear.
The fictional owners spent eighteen months reducing creditor days, selling an unused yard and cutting the overdraft before reapplying. With liabilities down to $3,800,000 and cash generation up to $560,000, the ratio reached roughly 15% and the loan was approved.
Watch out
Common mistakes.
- Using only long term debt in the denominator, which flatters the ratio for businesses that fund themselves through overdrafts and stretched supplier payments.
- Comparing the ratio across industries without adjustment, since asset heavy sectors naturally carry more debt and more depreciation than service businesses.
- Reading a single year in isolation, when a temporary fall caused by planned investment looks identical to a permanent deterioration.
Questions
People also ask.
Is a higher solvency ratio always better?
Generally yes for safety, though a very high figure can mean the business is under borrowed and is funding growth with expensive equity when cheaper debt was available.
Why add depreciation back to profit?
Because depreciation reduces reported profit without any cash leaving the business, so adding it back gives a closer approximation of the cash available to service debt.
How does the solvency ratio differ from the current ratio?
The solvency ratio tests long term debt repayment capacity from annual cash generation, while the current ratio tests whether short term assets cover short term liabilities right now.
