What it means
Every asset a business owns has been paid for by someone, either the owners through share capital and retained profits, or outsiders through loans, overdrafts and unpaid supplier bills. This ratio simply measures the owners' share of that funding, and because assets always equal equity plus liabilities, the rest of the balance sheet is the mirror image.
The reason it matters is the cushion it represents. Equity absorbs losses first, so a company where owners funded half the assets can suffer a serious setback and still meet its obligations, while one funded 90% by debt has very little room before lenders are at risk.
Lenders and credit insurers look at it constantly, and many loan agreements contain covenants requiring the ratio to stay above an agreed floor. Breaching that floor can make a loan repayable immediately, which is why finance directors watch the number even when trading is comfortable.
There is no single right level, because it depends on how predictable the cash flows are. Utilities and property companies with stable contracted income can run comfortably on low equity proportions, while a fashion retailer or a mining exploration business needs a much thicker equity cushion.
The ratio is closely related to the debt to asset ratio, which is just one minus this figure, and to the equity multiplier used in return on equity analysis. All three are different views of the same underlying question: how much of the business belongs to the owners once the debts are counted.
In practice
Real-world examples.
Example
A family owned engineering firm has never borrowed and shows an equity to asset ratio of 88%. It sails through a recession without lender pressure, though its owners accept that returns on their capital are lower than they could be with sensible borrowing.
Example
A hotel group refinances to fund an acquisition and sees the ratio fall from 45% to 22%. Its credit rating is downgraded, the interest rate on its next facility rises by more than a percentage point, and the board commits to rebuilding the ratio over three years.
Example
A software business raises a large funding round and briefly shows a ratio above 90% because the balance sheet is mostly cash. As it spends that cash on salaries and acquisitions the ratio falls steadily, which is expected rather than alarming.
Think of it
“Equity to assets shows what portion of your assets you actually own-equity's share of total assets.
Formula
Calculation
Equity to asset ratio = total shareholders' equity / total assets
A regional distribution company has total assets of $45,000,000 on its balance sheet, made up of warehouses, vehicles, stock and receivables. Shareholders' equity, which is share capital plus accumulated retained profits, stands at $18,000,000.
The equity to asset ratio = $18,000,000 / $45,000,000 = 0.40, or 40%. That means creditors and lenders funded the other $45,000,000 - $18,000,000 = $27,000,000, giving a debt to asset ratio of 60%. The equity multiplier is the inverse, 1 / 0.40 = 2.5 times, telling you assets are two and a half times the size of the equity base. If a downturn wiped $9,000,000 off asset values, equity would absorb the whole hit and fall to $18,000,000 - $9,000,000 = $9,000,000 against assets of $36,000,000, dropping the ratio to 25% and probably breaching a typical bank covenant.Case study
Seen in the real world.
This is an illustrative and entirely fictional case. Pennine Textiles, an invented fabric manufacturer, ran with an equity to asset ratio of 52% for a decade, which its bank considered conservative and its shareholders considered lazy. Under pressure to improve returns, the board borrowed $30,000,000 to buy back shares, taking the ratio down to 24%.
Return on equity duly jumped from 11% to 19% and the board was congratulated. Then a major customer moved production overseas, revenue fell 18% in a year, and a stock write down of $6,000,000 pushed equity down further, taking the ratio to 17% and breaching a covenant set at 20%.
In this fictional illustration the bank agreed to waive the breach only in exchange for a higher margin and a charge over the freehold site. Pennine survived, but the episode shows that a ratio which looks unnecessarily cautious in good years is exactly what buys negotiating room in bad ones.
Watch out
Common mistakes.
- Assuming a higher ratio is always better, when a very high figure can mean the owners are funding assets that cheaper borrowing could support, dragging down returns.
- Comparing the ratio across industries, when a property company and a consultancy have entirely different sensible ranges.
- Using book equity without checking for large intangible balances, since goodwill from past acquisitions can inflate the ratio while providing no real loss absorbing cushion.
Questions
People also ask.
How does this relate to the debt to asset ratio?
They add up to 100%, so an equity to asset ratio of 40% automatically means a debt to asset ratio of 60%.
What is a safe level?
It varies by sector, but many lenders to ordinary trading companies look for at least 30% to 40% and start asking questions below that.
Does a loss change the ratio immediately?
Yes, because losses reduce retained profits and therefore equity, which is why a run of losses can trigger a covenant breach even if no new debt has been taken on.
