Many business owners measure success by sales. Sales matter, but they are only the starting point. What you actually keep depends on everything that happens after the sale.
From sales to what you keep
Here is a simple example for a small trading business with $100,000 in sales for the month.
| Step | Amount |
|---|---|
| Sales (revenue) | $100,000 |
| Cost of goods sold | −$60,000 |
| Gross profit (40%) | $40,000 |
| Salaries | −$14,000 |
| Rent and utilities | −$6,000 |
| Delivery, software and other costs | −$8,000 |
| Operating profit | $12,000 |
| Loan interest | −$1,500 |
| Income tax (about 29%) | −$3,000 |
| Net profit | $7,500 |
Out of $100,000 in sales, the business keeps $7,500, a 7.5% net margin. That is normal for trading businesses, but it surprises many owners.
And then there is timing
Even the $7,500 may not be in the bank. If half of this month's sales are on 60-day credit, $50,000 of revenue has not been collected yet. You can be profitable on paper and short of cash at the same time.
Three numbers to track every month
- Gross margin %. If it drops, your pricing or purchase costs need attention.
- Overheads as a % of sales. Fixed costs should grow slower than sales.
- Days to collect (DSO). The longer customers take to pay, the more cash you need to run the business.
How to keep more of every sale
- Know your margin by product. Some best-sellers may barely break even. Push the profitable ones.
- Review prices every quarter. A 3% price increase often adds more to profit than a 10% rise in sales.
- Cut costs that do not drive sales. Unused software, idle space and duplicate subscriptions add up.
- Shorten credit terms. Faster collection does not change profit but makes it real cash sooner.
Frequently asked questions
What is a good net profit margin for a small business?
It varies by industry. Service businesses often achieve 15% to 25%, while retail and distribution businesses commonly see 3% to 10%. Compare yourself with businesses in your own industry.
What is the difference between gross profit and net profit?
Gross profit is sales minus the direct cost of the goods or services sold. Net profit is what remains after all other expenses, interest and tax are also deducted.
How can I increase the amount I keep from each sale?
Raise prices where you can, reduce direct costs through better supplier terms, cut overheads that do not drive sales, and focus on your highest-margin products or customers.
