7 Numbers Every Business Owner Should Know
Running a business means making decisions constantly.
Should you hire? Raise prices? Increase marketing? Buy equipment? Take money out of the company? Invest in growth?
The quality of those decisions depends heavily on the quality of the information behind them.
Many business owners know their turnover and bank balance, but those two numbers alone do not tell you whether the business is healthy.
A stronger approach is to monitor a small set of financial numbers consistently.
You do not need to become an accountant. You simply need to understand which figures matter and what they are telling you.
1. Revenue
Revenue is the total income generated by the business before costs are deducted.
It is useful because it shows whether sales are increasing, stable or falling.
However, revenue should never be viewed in isolation.
A business can grow revenue while becoming less profitable.
Review revenue alongside:
- Gross profit
- Net profit
- Customer numbers
- Average transaction value
- Sales by service
- Sales by customer type
This helps you understand whether growth is genuinely improving the business.
2. Gross profit
Gross profit is the amount left after deducting the direct costs of delivering your products or services.
These costs may include:
- Materials
- Direct labour
- Subcontractors
- Delivery
- Commission
- Production costs
For example:
- Revenue: £100,000
- Direct costs: £60,000
- Gross profit: £40,000
This tells you how much money remains to cover the wider overheads of the business.
Gross profit is particularly useful when comparing products, services or customer groups.
3. Gross profit margin
Gross profit margin expresses gross profit as a percentage of revenue.
In the example above:
- Revenue: £100,000
- Gross profit: £40,000
The gross margin is 40%.
This percentage is often more useful than gross profit alone because it allows you to compare performance over time.
If revenue is rising but gross margin is falling, costs may be increasing faster than prices.
Possible causes include:
- Supplier increases
- Wage increases
- Discounts
- Underpricing
- Higher delivery costs
- Lower-margin work
A declining margin should not be ignored.
4. Net profit
Net profit is what remains after all business expenses have been deducted.
This may include:
- Salaries
- Premises
- Insurance
- Software
- Marketing
- Professional fees
- Utilities
- Finance costs
- Administration
Net profit shows whether the business is actually creating a financial return after covering its full cost base.
A company may generate strong sales but weak net profit because overheads have become too high.
Regular accountancy and financial reporting can help business owners understand how revenue translates into actual profit.
5. Cash available
Profit and cash are not the same thing.
A business may be profitable but still have limited cash because money is tied up in:
- Unpaid invoices
- Stock
- Equipment
- Tax liabilities
- Loan repayments
- Director withdrawals
Review the actual cash position alongside upcoming commitments.
Ask:
- What is in the bank today?
- What tax is already owed?
- What payments are due this month?
- What customer receipts are expected?
- What cash reserve should remain untouched?
Do not assume that every pound in the bank is available to spend.
6. Amount owed by customers
Your aged debtor balance shows how much customers owe the business.
A growing debtor balance may indicate that:
- Sales are increasing
- Customers are paying more slowly
- Credit control is weak
- Payment terms are too generous
- Some invoices are disputed
Review:
- Total amount outstanding
- Invoices over 30 days
- Invoices over 60 days
- Invoices over 90 days
- Customers who repeatedly pay late
Improving collections can strengthen cashflow without increasing sales.
Accurate bookkeeping makes it easier to monitor outstanding invoices and understand who owes the business money.
7. Break-even point
Your break-even point is the level of sales required to cover your costs.
Below break-even, the business is losing money.
Above break-even, it begins generating profit.
Understanding this number helps with:
- Pricing
- Sales targets
- Recruitment
- Budgeting
- Expansion
- Marketing decisions
For example, if your monthly fixed costs are £20,000 and your average gross margin is 50%, the business needs £40,000 of revenue to generate £20,000 of gross profit and cover those fixed costs.
Once you know your break-even point, financial decisions become much easier to assess.
Why these numbers should be reviewed together
One number rarely tells the whole story.
For example:
Revenue might rise while:
- Gross margin falls
- Net profit falls
- Customer debts increase
- Cashflow gets worse
Alternatively, revenue might stay flat while profit improves because:
- Prices increased
- Costs were reduced
- Unprofitable work was removed
- Productivity improved
The strongest financial decisions come from reviewing the numbers together rather than focusing on one headline figure.
How often should you review them?
For many businesses, monthly reviews are appropriate.
Fast-growing businesses or those with tight cashflow may need to review certain figures more frequently.
At minimum, regularly monitor:
- Revenue
- Gross profit
- Gross margin
- Net profit
- Cash
- Debtors
- Break-even
Trends matter more than isolated figures.
Common mistakes
Business owners often:
- Focus only on turnover
- Judge performance from the bank balance
- Ignore gross margin
- Let overdue invoices build up
- Review figures only at year-end
- Set targets without knowing break-even
- Compare sales without comparing profit
Avoiding these habits improves financial visibility significantly.
Frequently Asked Questions
What is the most important business number?
There is no single number. Revenue, profit, cashflow and margins all provide different information and should be reviewed together.
Is turnover the same as profit?
No. Turnover is total sales before expenses. Profit is what remains after relevant costs are deducted.
Why can a profitable business have no cash?
Money may be tied up in unpaid invoices, stock, assets, tax liabilities or debt repayments.
How often should I review business performance?
Monthly reporting is suitable for many businesses, although cash and overdue invoices may need more frequent review.
Can an accountant help me understand these figures?
Yes. Good management reporting can turn accounting data into information you can actually use. Merranti’s accountancy services can help businesses gain clearer visibility over performance.
