What Is Gearing Ratio? How to Calculate It and What It Means for Your Business (2026)

August 17, 2026 4 Min Read

Gearing ratio measures how much of a business is funded by debt compared to equity. A high gearing ratio means debt does most of the heavy lifting. A low one means the owner’s own money carries more of the load.

Lenders check it before they approve finance. Investors check it before they buy in. Either way, it’s one of the fastest ways to size up how risky a business’s funding mix really is.

Quick Answer

Gearing ratio compares a business’s debt to its equity, usually expressed as a percentage. Below 25% is generally seen as low gearing, 25–50% as moderate, and above 50% as high. Lenders use it to judge financial risk before extending credit.

How to Calculate the Gearing Ratio

There are two common formulas, and both are used in practice:

Debt-to-Equity Gearing = (Total Debt ÷ Total Equity) × 100

Debt-to-Capital Gearing = (Total Debt ÷ (Total Debt + Total Equity)) × 100

Take a business with $300,000 in debt and $600,000 in equity. The debt-to-equity version gives (300,000 ÷ 600,000) × 100, or 50%. The debt-to-capital version gives (300,000 ÷ 900,000) × 100, or roughly 33%. Both describe the same business, just from a slightly different angle, so it’s worth knowing which one a lender means before comparing numbers.

What Counts as a Healthy Gearing Ratio

There’s no single right answer, but three rough bands are widely used:

Below 25% — low gearing. Debt plays a small role. Safer, though it can also mean missed chances to grow faster using borrowed capital.
25% to 50% — moderate gearing. Often seen as a healthy balance between debt-funded growth and staying stable.
Above 50% — high gearing. Debt carries most of the weight. Risk climbs, even though growth can move faster too.

Industry matters here, too. Capital-heavy sectors like construction or factories often run higher gearing simply because the gear and infrastructure cost so much. Service businesses, with fewer big assets to finance, usually sit lower.

Why Lenders and Investors Care

A gearing ratio is a quick read on how much risk a business carries. Lenders use it to decide whether to approve a loan, and at what interest rate — a business already loaded with debt looks riskier to lend to again. Investors use it the same way, since high gearing means more of the business’s future profit needs to go toward paying down debt before anyone else sees a return.

None of this means high gearing is always bad. A business using debt well, to fund growth that pays for itself, can outperform one that stayed debt-free but grew slowly. The ratio just flags where to look closer.

Gearing Ratio vs. Debt-to-Equity Ratio

These terms get used almost the same way, and in the debt-to-equity version of the formula, they’re the same sum. The difference is really just labeling: “gearing ratio” is the broader term, and it can be calculated either against equity alone or against total capital. “Debt-to-equity ratio” specifically refers to the first version. When someone quotes a gearing figure, it’s worth checking which formula they used before comparing it to another business.

How to Improve a High Gearing Ratio

A few practical levers exist for a business carrying more debt than it would like:

Pay down existing debt before taking on new financing.
Reinvest profit into the business instead of drawing it all out, building equity over time.
Raise new equity by bringing in an investor or partner, rather than borrowing again.
Avoid extra new debt, especially for assets that don’t directly grow revenue.

Common Mistakes

A handful of misreads show up often:

Comparing gearing across industries without context. A 60% ratio might be normal for a property developer and alarming for a consultancy.
Using the wrong formula when comparing figures. Debt-to-equity and debt-to-capital give different numbers for the same business.
Ignoring the trend. A single gearing snapshot matters less than whether it’s climbing or falling over time.
Treating low gearing as always better. Very low gearing can also mean a business isn’t using debt to grow when it reasonably could.

FAQ

What is a good gearing ratio?
Generally 25–50% is considered a healthy, moderate range, though the right number depends heavily on the industry.

How do you calculate gearing ratio?
Divide total debt by total equity, then multiply by 100. Some versions divide debt by total capital (debt plus equity) instead.

Is a high gearing ratio bad?
Not always. It signals higher financial risk, but a business using debt well to fund growth can still perform well with a higher ratio.

What’s the difference between gearing ratio and debt-to-equity ratio?
In its debt-to-equity form, they’re the same calculation. “Gearing ratio” is the broader term and can also be measured against total capital instead of equity alone.

Why do lenders check gearing ratio?
It shows how much of the business is already funded by debt, which affects how risky a new loan would be and what interest rate makes sense.

Can gearing ratio be too low?
Yes, in a sense. Very low gearing can mean a business is missing chances to grow using cheap borrowed capital instead of only its own funds.
