How much debt is too much for a small business?
It is the question almost every owner asks at some point, usually late at night. The honest answer is that there is no single number that is safe and no single number that is fatal. What decides whether your debt is too much is not its size but whether your business can comfortably service it, and how it sits against what you own. This is a calm look at how to think about that, without the spreadsheet anxiety.

Is there a safe amount of debt for a small business?
People often hope for a rule of thumb, a ratio they can measure themselves against and feel reassured. The trouble is that the same dollar figure can be perfectly healthy for one business and dangerous for another. A consultancy with low overheads and steady retainers can carry debt that would sink a seasonal retailer with thin margins. Debt is not good or bad in itself. It is a tool, and the only meaningful question is whether the business it is funding generates enough reliable cash to repay it without starving everything else. That is why a number alone never tells you much.
Can you service the debt from your cash flow?
The single most useful test is serviceability: after you have paid your suppliers, your staff, your tax, and yourself something reasonable, is there enough left over to meet your repayments without having to borrow again to do it? If the repayments fit comfortably within your ordinary trading surplus, the debt is being carried by the business rather than the other way around. If you find yourself timing payments, drawing on a facility to cover another facility, or leaning on the ATO as an informal overdraft, the debt has started to drive the business, and that is the point at which the amount has become too much regardless of what the headline figure is. Looking at the months ahead rather than today's bank balance is what makes this visible. The cash runway calculator works out how long your cash lasts at your current burn rate, which is the clearest way to see whether your repayments still have room to breathe.
How does your debt sit against your assets?
Serviceability tells you whether you can meet repayments as they fall due. The other half of the picture is your balance sheet: what you owe against what you own. A business can be servicing its debt today and still be carrying more liabilities than assets, which leaves it with no cushion if a large customer is lost or a season turns out poorly. Accountants look at this through ratios such as the current ratio, the quick ratio, and debt-to-equity, which sound technical but simply describe how much margin you have between your obligations and your resources. The solvency ratio calculator works these out from your balance sheet in under a minute, so you can see whether the debt sits on a solid base or a thin one.
What are the warning signs debt has tipped over the line?
The shift from manageable debt to too much debt is rarely a single event. It shows up as a pattern. New borrowing starts being used to cover old borrowing rather than to grow anything. Repayments are made later and later, and tax lodgements slip. The director starts putting personal money in to keep the lights on, or personal cards quietly become part of the working capital. Each of these on its own can be a normal bump, but together they are the business telling you the debt load has outgrown what the trading can support. Noticing the pattern early is what keeps your options open, because the responses available to a business that acts in the first month are far wider than those available to one that waits a year.
What to do if the debt has become too much
If you have concluded the debt is heavier than the business can reasonably carry, the useful next step is not panic but clarity. Work out, on real numbers, how much surplus the business actually produces and what would have to change for the repayments to fit inside it. Sometimes the answer is a pricing or cost adjustment; sometimes it is renegotiating terms with the people you owe before anything is in default; and sometimes it is getting early advice about a formal option. What rarely helps is treating the size of the number as a verdict. A large debt that is being serviced comfortably is fine. A modest debt the business can no longer carry is the one worth acting on. Knowing which you have is the whole point.
