Capital Gearing Ratio Calculator
Two companies can carry the same amount of debt and be in completely different positions, because what matters is not the debt figure but how much of the whole capital structure it represents. The capital gearing ratio makes that proportion explicit: the share of a company capital that carries fixed obligations, interest on debt and fixed preference dividends, against the ordinary equity that absorbs whatever is left.
Enter interest-bearing debt, preference share capital and ordinary equity. The calculator returns the gearing ratio as a percentage of total capital, a plain leverage verdict, the debt-to-equity equivalent, and the percentage share of each component, so you can read the same structure in whichever language your textbook, lender or exam uses.
Uses book values as entered. Market-value gearing can differ significantly; this is an analytical ratio, not investment advice.
Quick Answer
Key takeaways
- Gearing here means fixed-interest capital (debt plus preference shares) as a share of total capital. Other sources define gearing as debt divided by equity; this page shows both figures so the two never get confused.
- The bands the tool applies: above 50% is high, 25% to 50% is moderate, below 25% is low. The worked example lands exactly on the high-gearing boundary and is classed moderate.
- Preference shares count as geared capital because their dividend is fixed and paid first, whatever the legal label says.
- Gearing is risk, not quality: it magnifies gains in good years and losses in bad ones by exactly the same mechanism.

How to use the capital gearing ratio calculator
Take the three figures from the financing side of the balance sheet. Interest-bearing debt means borrowings that charge interest: bank loans, bonds, debentures. Leave out trade payables, accruals and tax owed, because none of those carry a fixed interest obligation in the sense this ratio measures. Preference shares go in at their capital value; enter 0 if the company has issued none, which is common for private companies. Ordinary equity is ordinary share capital plus retained earnings and reserves, the residual layer.
Press Calculate and read the output in order: the ratio itself, the verdict band it falls in, the debt-to-equity translation, and the mix. If one input is missing from your source accounts, note that a blank is an error here, not a zero: the tool asks you to enter 0 deliberately, so a forgotten field cannot quietly flatter the ratio.
The gearing formula, and an honest warning about definitions
The definition used here is the textbook capital gearing definition: fixed-charge capital as a proportion of all capital.
The warning: gearing has no single universal formula. Several ranking calculators and guides, including the Xero gearing ratio guide, define the gearing ratio as total debt divided by equity, which on these same figures gives 100%, not 50%. Neither is an arithmetic error; they are different ratios sharing a name. The debt-over-equity version is really the debt-to-equity ratio expressed as a percent, and this calculator hands it to you as the debt-to-equity equivalent (1.00 here). Before comparing a gearing figure from any source against a benchmark, check which definition produced it, or you will be comparing two different measurements.
Worked example: a company exactly on the boundary
| Component | Amount | Share of total |
|---|---|---|
| Interest-bearing debt | $400,000 | 40.0% |
| Preference shares | $100,000 | 10.0% |
| Ordinary equity | $500,000 | 50.0% |
| Total capital | $1,000,000 | 100% |
| Fixed-interest capital (debt + preference) | $500,000 | 50.0% geared |
Half of this company capital is spoken for before ordinary shareholders see a cent: interest on $400,000 of debt and the fixed dividend on $100,000 of preference capital come out of profits first, in good years and bad. That is precisely what the 50.0% figure is telling you, and why the verdict sits one step below high: a modest profit fall would push fixed charges to the front of a shrinking queue.
Reading the bands: low, moderate and high gearing
| Gearing | Band | What it means in practice |
|---|---|---|
| Below 25% | Low | Equity-funded. Fixed charges are a small claim on profits, so earnings per share are stable, but cheap leverage may be going unused. |
| 25% to 50% | Moderate | Debt is working for shareholders without dominating. Most lenders view this zone as balanced for established businesses. |
| Above 50% | High | Fixed obligations dominate. Returns on equity swing hard with trading conditions, and new lenders will price that risk or decline. |
Judge the band against the industry before judging the company. A utility with regulated, predictable cash flow can service high gearing safely for decades; a cyclical retailer at the same ratio is one bad Christmas from a covenant breach. Gearing also sits inside a family of capital measures: banks answer to a regulatory version through the capital adequacy ratio calculator, the day-to-day financing mix is tracked with the capital balance calculator, and if you are comparing periods, the average capital employed calculator smooths the capital base across a full period instead of a single balance-sheet date.
Why preference shares count, and what leverage does to shareholders
Preference shares are legally equity and economically close to debt. Their dividend rate is fixed when the shares are issued, they rank ahead of ordinary shares for payment, and in many structures unpaid dividends accumulate. For risk purposes, what matters is the behaviour: a fixed claim that must be serviced before the residual owners. That is why the numerator of this ratio includes them, and why leaving them out, as simpler debt-only tools do, understates the fixed burden.
The shareholder effect is magnification. Suppose this company earns $150,000 before interest and preference dividends, and fixed charges total $50,000: $100,000 remains for ordinary shareholders, a 20% return on their $500,000. If profits rise by a third to $200,000, the residual jumps by half to $150,000, because the $50,000 charge did not move. Run the film backwards and a one-third profit fall cuts the residual in half. That asymmetry is the entire story of gearing, and the reason a fund shareholder reading a distribution should separate company leverage from fund payouts: the capital gains distribution calculator covers the payout side of that picture.
What competing calculators miss
Miss 1: one name, three formulas, no disclosure. Ranking tools variously compute debt over equity, long-term debt over debt plus equity, or fixed capital over total capital, and label all three capital gearing. The numbers are not interchangeable, and most pages never state which one they used. This page states its formula in the result itself and prints the debt-to-equity equivalent alongside.
Miss 2: preference capital ignored. Debt-only numerators treat a company funded heavily by preference shares as ungeared, even though its fixed dividend burden may exceed its interest bill. Here preference capital is a first-class input, with 0 accepted for companies that have none.
Miss 3: a number with no verdict and no mix. A bare percentage leaves the reader to find a benchmark table elsewhere. This tool bands the result (low, moderate, high), shows the workings line with your actual dollar figures substituted in, and breaks the mix into its three shares so the structure, not just the headline, is visible.
Frequently Asked Questions
The share of a company total capital that carries fixed obligations: (interest-bearing debt + preference shares) divided by total capital, times 100. On the worked example, $500,000 of fixed-interest capital over $1,000,000 of total capital gives 50.0%. It measures how much of the financing stack must be serviced before ordinary shareholders are paid.
On the bands this tool applies: above 50% is high gearing, 25% to 50% is moderate, and below 25% is low. Exactly 50% is classed moderate, on the boundary of high. Treat the bands as a starting point, not a law: capital-intensive industries with stable cash flows run higher ratios safely than cyclical businesses can.
Because they behave like debt for risk purposes. Their dividend is fixed at issue, it is paid before any ordinary dividend, and unpaid amounts often accumulate. Legally they are equity, but the fixed claim on profits is what gearing measures, so they belong in the numerator next to interest-bearing debt.
Gearing, as calculated here, is fixed-interest capital as a percentage of total capital. Debt-to-equity is fixed-interest capital divided by equity alone. They describe the same structure: a gearing of 50% always equals a debt-to-equity of 1.00. Some sources use gearing to mean debt-to-equity as a percent, which is why this calculator prints both figures.
Not automatically. Gearing magnifies outcomes in both directions: fixed charges stay flat while profits grow, so equity returns surge in good years, and the same charges consume a shrinking profit pool in bad years. High gearing is a risk position, not a quality verdict. It suits stable, predictable cash flows and punishes volatile ones.
This calculator uses the book values you enter, taken from the balance sheet. For listed companies, market-value gearing can differ significantly, because the market value of equity moves daily while book equity changes slowly. Book-value gearing is the standard for credit review and exams; market-value gearing is the sharper tool for listed-company investment analysis.
There is no universal figure. As a rough orientation, many established businesses sit comfortably in the 25% to 50% moderate band. Utilities and infrastructure firms often run higher on regulated cash flows; young and technology firms often run near zero because lenders will not extend them debt. Compare within the sector, and compare the same definition.
Yes. Gearing is a standard input in credit review before extending further debt, and loan agreements often cap it through covenants. A company already above 50% should expect new borrowing to be expensive, secured, or refused, because the lender can see exactly how much of the profit stream is already committed to existing fixed charges.
