Negative net cash: what it means, and how common it is.

What negative net cash actually means

Take the cash in the bank, add the money customers owe you, subtract the money you owe suppliers, HMRC and everyone else falling due. If the answer is below zero, the bills falling due are bigger than the cash you hold plus what you are owed: the bank balance may look fine on a Tuesday, but on its own it will not cover them. It is not automatically fatal, plenty of businesses trade through it, and whether it becomes a problem depends on what comes in before the bills fall due (new sales, customer payments, funding) and when they fall due. But it can leave little padding between a normal shock and a crisis, and if it does, the options get expensive quickly. It is the "cliff edge" position in the five cash positions.

How common is it? A random sample of 10,000 filings

We drew a random sample of 10,000 sets of accounts filed at Companies House in June and July 2026, kept the 7,481 trading companies whose balance sheets add up, and looked at what those balance sheets actually said. Each figure has its own base, because the smallest (micro-entity) accounts do not show a cash line, so the cash figures come from companies filing fuller, non-micro accounts:

• About 4 in 10 had negative net cash. 41.2% (1,227 of 2,980 non-micro accounts with usable cash and debtors) owed more within a year than what was in the bank plus what they were owed. Debtors are taken as reported and can include prepaid expenses, so this can flatter some companies.
• Nearly 2 in 3 held less cash than the creditors due within a year. 63.7% (2,085 of 3,275 non-micro accounts with usable cash). On their balance sheets, most of those companies could not have covered the creditors due within the year from the cash they held; whether that bites depends on what comes in before those bills fall due.
• 1 in 5 had £1,000 or less in the bank. 19.5% (637 of 3,275). Not a cushion. A rounding error.

Across all 7,481 companies, 37.1% (2,779) were in net current liabilities: current assets, cash included, smaller than the creditors due within a year.

So what? These are balance sheets at each company's year-end, filed some months later, so they are a snapshot, not a forecast: the data does not tell us which of these companies will get into trouble. What it does show is that a thin cash position is common. If your own position is weak, you are not unusual, but the companies that come through are the ones that see it early, while the fixes are still cheap. The full method, who is left out and the caveats are on the methodology page.

If that is you: what to do this week

The point of knowing your net cash is not the number, it is the sequence it puts you in. Know where you stand before you take off, not mid-flight: check your net cash and your cushion in months, chase the debtors that bring it back above the line, and know what is leaving before it leaves. Cash is the lifeblood of every enterprise; the whole reason we condensed this down to nearly one recognisable number is so an owner can see it quickly and act on it, rather than find out from the bank.

For accountants and bookkeepers: a reference point for your client list

A filing sample is not your client list, but it is a useful reference point. If your clients look like this sample, some of them are likely to be below the line, and by the time accounts are filed the year-end they describe can be the best part of a year old, so the live position may have moved a long way since. The practical move is knowing which of your clients sit below the line THIS week rather than at year-end: a weekly cash briefing per client makes each client's current position visible before it becomes a phone call.

About this video: it was recorded in August with our first reading of the data. Its title and its description of the sample size are superseded. The headline ratios it quotes are close to the corrected ones, but the corrected figures, with their bases, are the ones on this page and in the methodology.
