Running a business takes time, energy and constant decision-making. Most business owners are already juggling sales, staff, customers and operations, without having hours spare to analyse financial reports.
That's why it helps to focus on a handful of key numbers each month.
The right figures can quickly tell you whether your business is healthy, profitable and financially stable. They can also highlight problems early, before they become expensive issues.
At DWilkinson&Company, we help business owners understand the numbers that really matter, without overcomplicating things. Here are five important figures every business owner should monitor each month.
What is my gross profit margin telling me?
Your gross profit margin shows how much profit you make after covering the direct costs of delivering your product or service. In simple terms, it tells you how efficiently your business is operating.
For example, it should include all your turnover/income, less the cost of sales, i.e., the direct costs associated with selling your products/services, such as stock or raw materials, direct labour costs, delivery/shipping costs, etc. It does not include your rent, utilities bills, business rates, admin, marketing, office salaries, etc.
When reviewing your gross profit margin, the calculation is: total sales minus the cost of sales = gross profit. Then divide the gross profit by your total sales and multiply by 100 to get your gross profit margin (percentage).
If sales are increasing, but your gross profit margin is shrinking, it could mean your costs are rising too quickly, or your pricing is too low. Many businesses focus on turnover, but sales revenue alone does not guarantee the business will be profitable.
Monitoring your gross profit margin monthly helps you spot trends early. It allows you to review pricing, supplier costs and operational efficiency before profits start slipping away.
A healthy margin gives your business room to grow, invest and deal with unexpected costs.
How much cash does my business actually have available?
Profit is important, but cash is what keeps a business moving. Many profitable businesses still run into difficulties because they do not have enough cash available to pay wages, suppliers or tax bills when they fall due.
Your monthly cash position shows how much money is available in the business right now. It also helps you understand whether cash is improving or tightening over time.
Keeping a close eye on your cash flow enables you to plan ahead. You can prepare for quieter periods, large purchases or seasonal fluctuations without unnecessary stress.
It also helps prevent last-minute borrowing or difficult financial decisions.
Having clear visibility over cash gives you more confidence and control of your business.

Are my overheads becoming too high?
Overheads are the regular running costs of your business, such as rent, utilities, software, insurance and admin expenses.
Your overhead ratio compares these costs to your turnover. To calculate this, divide your total overhead costs by your total sales and multiply by 100.
If your overheads rise faster than sales, profits can disappear surprisingly quickly. This often happens gradually, making it difficult to notice without regular reviews.
Checking your overhead ratio each month helps you understand whether your business is staying lean and efficient.
It can also highlight areas where spending may have drifted over time. Small monthly savings across several areas can make a significant difference to annual profitability.
Businesses that regularly monitor overheads are often quicker to adapt when costs increase.
Is my business making a net profit each month?
Your net profit is the amount left after all business costs have been deducted. This is one of the clearest indicators of whether your business model is working.
Some business owners only review profits at year-end, but by then, it may be too late to address problems that have been building for months.
Monthly profit reviews help you understand how the business is really performing. You can compare results against previous months, budgets or targets and make informed decisions based on accurate information.
Even small changes in profit trends can reveal important insights about pricing, staffing levels or rising costs.
Understanding your net profit helps you make better commercial decisions with confidence.
Are customers paying me quickly enough?
Late payments can create serious pressure on cash flow, even when sales are strong. That's why it is important to monitor how quickly customers are paying their invoices.
Your debtor days figure shows the average number of days it takes customers to pay you. If this number starts increasing, it may indicate collection issues or financial struggles among your customers.
Reviewing this figure monthly helps you stay proactive. You may decide to tighten payment terms, improve credit control processes or follow up on invoices more consistently.
Getting paid faster improves cash flow, reduces stress and strengthens the overall stability of your business.
Why do these numbers matter so much?
Most business owners do not need pages of complicated reports every month. They need clear, reliable information to help them make quicker, better decisions.
By focusing on a small number of key financial figures, you can gain a much clearer understanding of how your business is performing without getting buried in detail.
The earlier you spot issues, the easier they are to fix.
