The debt-to-equity ratio (D/E) compares what a business owes to what its owners have invested. Divide total debt by total equity. A ratio of 1.0 means equal debt and equity - equally-split financing. Below 0.5 is conservative, 1-2 is moderate, above 2 is highly amplified and increases failure risk if revenue dips.
2M total debt against 4M equity = 0.5 D/E. Conservative, lots of room to take on growth debt. Flip it - 4M debt, 2M equity - and D/E becomes 2.0. Interest costs eat into profit, and any slowdown pushes the business toward breaching loan covenants.
Industries differ massively. Utilities routinely run D/E above 1.5 because stable regulated revenue supports heavy borrowing. Tech companies often run below 0.3 because intangibles don't make good collateral. Compare within industry, not.
Run it with sensible defaults
Using total debt of 2,000,000, total equity of 4,000,000, the calculation works out to 0.50. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Total Debt and Total Equity — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.
How the math works
D/E ratio = total debt ÷ total equity. Debt % of capital = debt ÷ (debt + equity). The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
What to do with a low result
A disappointing result is information, not a judgement. Pick the single input that dragged the figure down most and focus the next quarter on that one factor. Breadth-first improvement rarely works; depth-first on the worst input usually does.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.
£2,000,000 £ total debt ÷ £4,000,000 £ equity = 0.50.
