How to Tell If Your Business Is Financially Healthy: 7 Warning Signs

How to tell if your business is financially healthy involves more than checking whether it made a profit. The answer lies in how your margins, operating efficiency, borrowing and balance sheet perform together — and how those measures change over time.

A company may grow turnover while earning less on each sale, or maintain profits while relying on more borrowing and capital. Equally, a business investing for future growth may report modest current profits but remain financially resilient.

This guide explains seven warning signs that directors can identify in their management accounts, with practical calculations and questions to ask before making decisions.

At a glance: Seven warning signs in your company accounts

None of these signs necessarily means a business is in financial difficulty. Instead, look at the trend, the explanation and the commercial context.

Why a profitable business isn't necessarily financially healthy

The profit and loss account measures performance over a period. The balance sheet shows the company’s assets, liabilities and net assets at a particular date. Meanwhile management accounts bring these figures together so directors can monitor trends, compare results with budgets and assess whether the business is becoming stronger or weaker.

Profit and cash are not the same thing, but that distinction is explored in more detail in our separate guide, “Profitable Business but No Cash? Here’s Where the Money Goes”. Here, the focus is on what financial ratios and movements in the accounts reveal about performance and resilience.

No single ratio provides the answer. To tell whether your business is financially healthy, consider margins, efficiency, liquidity, borrowing commitments and the return earned on capital — in the context of the company’s sector and strategy.

1. Why are your sales growing but your profit margins shrinking?

Increasing sales should be good news. However, if the direct costs of delivering those sales rise faster than turnover, the company could be working harder without a corresponding improvement in profitability. Gross profit margin shows how much of each pound of sales remains after direct costs.

Gross profit margin = Gross profit ÷ Turnover × 100

Turnover increased by 30%, but gross profit rose by only 10.5%. The margin fell from 40% to 34% — a six-percentage-point reduction. At the previous 40% margin, £650,000 of sales would have generated £260,000 gross profit, £39,000 more than the £221,000 actually achieved. This is why turnover growth alone is an unreliable measure of trading strength.

What should directors investigate?

Examine supplier prices, discounting, product mix, production costs and work that has not been charged to customers. For service businesses, staff utilisation and job pricing may also matter. Lower margins can be a deliberate choice when entering a market, but directors should be able to explain the trade-off and assess whether it is sustainable.

2. Are your customers taking longer to pay their invoices?

Debtor days provide a useful measure of how efficiently the business converts credit sales into customer payments. In particular, check whether collection times are deteriorating relative to the company’s normal terms and historical performance.

Debtor days = Trade debtors ÷ Credit sales × Days in the period

If annual credit sales excluding VAT are £1.2 million and trade debtors excluding VAT are £180,000, debtor days are approximately 55. If the previous figure was 35 days, the additional 20 days represents roughly £65,750 more tied up in receivables at the same annual sales rate.

Moreover, a sustained rise can indicate weaker credit control, customer disputes or increased exposure to a small number of customers. Use comparable VAT treatment in the numerator and denominator. Average debtor balances can be more representative than a single year-end balance.

What should directors investigate?

Compare debtor days with agreed payment terms and prior periods. Review overdue invoices, disputed balances, customer concentration and the effectiveness of credit control. A subscription business paid in advance will naturally differ from a consultancy invoicing after delivery; trends within the same business are generally more informative than a single industry-wide target.

3. Is stock growing faster than the sales it supports?

Stock levels should reflect expected demand and the time needed to replenish products. If sales rise by 10% while inventory rises by 40%, directors should ask whether purchasing decisions are supported by forecasts or whether products are becoming harder to sell. Of course, seasonal buying or a planned launch may explain the change.

Inventory days = Average inventory ÷ Cost of sales × Days in the period

An increase in inventory days means stock is being held for longer relative to the cost of sales. That can point to slower demand, over-ordering or obsolete lines; alternatively, it may reflect a planned stock build. The ratio is most useful when compared with prior periods and purchasing plans.

What should directors investigate?

Review slow-moving products, purchasing forecasts, valuation and stock storage costs. Amazon and other marketplace sellers should also consider fulfilment and storage charges. Ultimately the aim is the right stock level, not necessarily the lowest.

4. Are Rising Overheads Eating Into Your Profits?

Additional staff, systems, premises and marketing may be necessary as a business grows. However, if gross profit increases by £40,000 while operating overheads rise by £65,000, operating profit falls by £25,000 despite stronger sales.

What should directors investigate?

This illustrates why directors should monitor overheads alongside gross profit, rather than looking at turnover growth in isolation.

Compare spending against budgets, prior periods and gross profit. Examine staffing, recurring software, premises and marketing. Then, distinguish necessary investment from costs that have increased without a clear commercial return.

5. Is Your Business Taking on More Debt Than It Can Afford?

Borrowing can be a sensible way to finance new equipment, stock, acquisitions or business expansion. However, as debt increases, so do interest costs and future repayment commitments. This can put pressure on the business, particularly if profits start to fall.

One useful measure is interest cover, which shows how comfortably operating profits can meet interest payments.

Interest cover = Operating profit before interest and tax ÷ Interest expense

For example, if a company makes an operating profit of £120,000 and pays £30,000 in annual interest, its interest cover is four times.

However, if operating profit falls to £60,000 while interest costs remain unchanged, interest cover drops to just two times. As a result, the business now has considerably less room to absorb a further decline in profits.

What should directors investigate?

Review outstanding borrowing, repayment dates, interest rates, loan covenants, security and any personal guarantees. Importantly, interest cover doesn't include capital repayments, so directors should also check whether forecast cash flow is sufficient to meet both interest and loan repayments.

6. Is Your Balance Sheet Hiding Financial Weaknesses?

Your balance sheet can reveal a great deal about the financial health of your business. However, positive net assets don't necessarily mean the company is financially secure. Equally, negative net assets don't automatically mean it's insolvent.

One useful measure is working capital, which shows the difference between short-term assets and liabilities.

Working capital = Current assets − Current liabilities

For example, if a company has current assets of £250,000 and current liabilities of £300,000, it has negative working capital of £50,000.

This could indicate pressure on cash flow, particularly if suppliers and other creditors need paying before customers settle their invoices. However, some businesses operate successfully with negative working capital because they receive customer payments before their own bills fall due.

What the Balance Sheet Doesn't Tell You

The figures on your balance sheet don't always tell the full story. For example, £200,000 tied up in overdue customer invoices and slow-moving stock is very different from having £200,000 available in the bank.

Consequently, directors need to consider the quality of their assets, how quickly they can be converted into cash and whether the amounts shown are realistically recoverable.

Director's loan accounts also deserve attention. Money the company owes to a director is a liability, whereas money a director owes to the company is an asset. However, an overdrawn director's loan account may also create additional tax liabilities and questions about recoverability.

7. Is Your Business Making the Most of Its Investment?

Making a profit is important, but how much money does your business need to generate that profit.

A company might report healthy earnings yet deliver a relatively modest return on the capital invested in it. For that reason, directors should look beyond the profit figure and consider how effectively the business uses its resources.

One useful measure is return on capital employed (ROCE).

ROCE = Operating profit ÷ Capital employed × 100

Capital employed can be calculated as total assets less current liabilities. However, whichever definition you use, it's important to remain consistent when comparing different periods or businesses.

Consider two companies reporting identical operating profits:

Both companies generate £100,000 in operating profit. However, Company B uses two and a half times as much capital to achieve that result, producing a return of just 8% compared with Company A's 20%.

That doesn't necessarily mean Company B is performing badly. For example, it may have invested heavily in new equipment, premises or expansion, with the benefits yet to appear in its profits.

Nevertheless, the comparison raises an important question: is the business generating a worthwhile return on the money tied up in it?

What should directors investigate?

Review the capital invested in the business alongside its operating profits. Consider whether major assets are being used effectively, whether recent investments are delivering the expected returns and how the company's performance compares with previous years.

In addition, consider the risks involved. A lower return may be understandable during a period of investment, but directors should be clear about when they expect that investment to generate additional profits.

Worked Example: Same Profits, Very Different Financial Health

Two businesses can report exactly the same profit while facing very different financial risks.

To illustrate this, let's compare two established companies operating in the same sector. Both have annual turnover of £1 million and operating profit of £120,000.

At first glance, their financial performance looks identical. However, a closer look at their accounts tells a different story.

Illustrative figures; the businesses have different operating cost structures.

Although both companies generate £120,000 in operating profit, Company A appears to be in a stronger financial position.

Its higher gross profit margin means it retains more from each pound of sales before operating overheads. Customers also pay more quickly, while stock spends considerably less time sitting in the business.

Company B, meanwhile, has more money tied up in customer invoices and inventory. It also carries substantially more interest-bearing debt, leaving it more exposed if trading conditions deteriorate.

Its interest cover of just two times is particularly important. This means operating profit is only twice its annual interest expense, compared with eight times for Company A.

However, these figures don't tell us everything. Company B may have invested in additional stock to support growth, extended credit terms to secure valuable customers or borrowed to finance assets that will generate future returns.

What should directors investigate?

Before drawing conclusions, review cash flow forecasts, debt repayment commitments, the quality of outstanding invoices, stock turnover and the reasons behind the differences.

Also, consider seasonality and whether the figures reflect normal trading conditions.

The key lesson is that profit alone doesn't tell you how financially healthy a business really is. Directors need to understand how that profit is generated, how much cash is tied up in the business and whether it can comfortably meet its financial commitments.

How Often Should Directors Check Their Company's Financial Health?

For most established businesses, waiting until the annual accounts are prepared is simply too late to identify potential problems.

Instead, directors should review their financial performance regularly, ideally through monthly management accounts. Comparing these figures with budgets and previous periods can help identify warning signs before they become more serious. 

The ICAEW's guidance on managing your business also highlights the importance of timely financial information, regular performance monitoring and comparing actual results against budgets.

The key measures to monitor include profit margins, debtor and stock turnover, borrowing commitments, cash flow and returns on investment.

However, there's little benefit in producing complicated financial reports that nobody uses. What matters is having accurate, up-to-date information that helps directors understand what's happening in their business and make informed decisions.

After all, statutory accounts tell you how your company performed over the financial year. Good management information helps you decide what to do next.

Why Financial Trends Matter More Than Perfect Ratios

A financially healthy business isn't necessarily the one growing fastest or reporting the highest profits.

What really matters is understanding how the different parts of the business fit together. Are profit margins improving? Are customers taking longer to pay? Is borrowing increasing faster than profits? And is the money invested in the business generating a worthwhile return?

Importantly, no single financial ratio tells the whole story.

For example, a falling profit margin isn't necessarily a problem if the business is investing in growth and management understands when that investment should start delivering results.

Similarly, negative working capital may be perfectly manageable for a business that receives customer payments before it needs to pay suppliers.

The real warning sign is when directors don't understand why their figures are changing or recognise the problem too late to do something about it.

Ultimately, a financially healthy company doesn't need perfect ratios. It needs reliable financial information, directors who understand what the figures are telling them and a willingness to act before small problems become much bigger ones.
