Knowing your business numbers means being able to say, from current records, how much the business earned, how much cash it has, who owes it money, and what it costs to produce a sale. An owner who knows these numbers can price correctly, spot problems early, and make decisions with confidence. An owner who does not is managing from the bank balance.
Which numbers should every business owner know?
| Number | What it tells you | Where to find it |
|---|---|---|
| Revenue | How much you sold | Profit and Loss statement |
| Gross margin | What is left after the direct cost of sales | Profit and Loss statement |
| Net profit | What is left after all expenses | Profit and Loss statement |
| Cash balance and runway | How long you can operate at current spending | Balance Sheet and cash forecast |
| Accounts receivable | Who owes you and how old the invoices are | Receivables aging report |
| Break-even point | The sales needed to cover all costs | Calculated from fixed costs and margin |
| Owner pay | What the business truly returns to you | Payroll and draws |
How do you calculate the numbers that matter most?
- Gross margin is revenue minus the direct cost of sales, divided by revenue.
- Net profit margin is net profit divided by revenue.
- Break-even sales is fixed costs divided by gross margin percentage.
- Cash runway is cash on hand divided by average monthly spending.
- Days sales outstanding is accounts receivable divided by average daily sales.
For example, a business with $40,000 in monthly fixed costs and a 50 percent gross margin needs $80,000 in monthly sales to break even.
Why is the bank balance not enough?
The bank balance shows cash today. It does not show bills that are due, payroll next week, taxes owed, or invoices customers have not paid. A business can have a healthy balance and be losing money, or a low balance and be highly profitable. Only the financial statements show which is true.
What happens when an owner does not know the numbers?
- Prices are set by guesswork and margins erode.
- Cash shortages arrive without warning.
- Unprofitable customers and services go unnoticed.
- Tax bills come as a surprise.
- Lenders and buyers lose confidence when questions cannot be answered.
How do you start knowing your numbers?
- Bring the books current and reconcile every account.
- Get a Profit and Loss statement and Balance Sheet every month.
- Choose five to seven numbers and track them on one page.
- Compare each month with the prior month and the same month last year.
- Review the results with someone who can explain what changed and why.

Common questions
It means understanding the key financial figures of your business, such as revenue, margins, profit, cash, and receivables, well enough to use them in decisions.
Review the full financial statements monthly and check cash and receivables weekly.
Cash is the most urgent, because a business closes when it runs out. Gross margin is often the most revealing, because it shows whether each sale is worth making.
A bookkeeper keeps the numbers accurate, and an accountant or fractional CFO explains what they mean. Sunderland Valley Enterprises provides both, prepared by a former Chief Financial Officer.
