Most small businesses can run on five or six financial metrics: gross margin, net profit margin, current ratio, quick ratio, how many days customers take to pay, and debt against equity. Get those onto one page every month and you’ll see trouble weeks before the bank does.
Which financial metrics tell you the most?
Dozens of ratios exist. Few of them change what you do on a Tuesday. The ones below come from the BDC’s guide to financial ratios, which is written for Canadian owners, and each answers a plain question.
Can I pay my bills this month? Am I making money on what I sell? Do customers pay fast enough? Am I borrowing too much? That’s it. If a number doesn’t answer one of those, leave it out of the monthly review.
| Metric | Formula | Benchmark on the BDC page |
|---|---|---|
| Current ratio | Current assets / current liabilities | 1.0 or greater is generally acceptable |
| Quick ratio | (Cash + receivables + short-term investments) / current liabilities | Same idea, 1.0 or greater |
| Gross profit margin | (Revenue minus direct costs) / revenue | Varies by industry |
| Net profit margin | Net income / revenue | Depends on the industry |
| Debt to equity | Total liabilities / shareholders’ equity | Lower is healthier |
| Receivable days | Average receivables / revenue x days in period | Most companies aim for 30 to 45 days |
| Inventory turnover | Cost of goods sold / average inventory | Higher is better, varies by industry |
How do you read a current ratio without fooling yourself?
BDC’s own wording on the liquidity ratios is short and worth keeping on a sticky note.
For both the quick ratio and the current ratio, a ratio of 1.0 or greater is generally acceptable
4 types of financial ratios to assess your business performance, BDC, bdc.ca
Now suppose you hold $90,000 in cash, receivables and stock that will turn into cash within a year, and you owe $60,000 over the same period. That’s a current ratio of 1.5. Comfortable on paper.
But if $50,000 of that $90,000 is unsold inventory, the quick ratio, which leaves inventory out, is $40,000 over $60,000, or 0.67. Same business, very different picture. This is why the quick ratio exists, and why you should look at both.
A ratio above 1.0 doesn’t mean the cash arrives before the rent does. Timing is what kills small firms, and ratios only show a snapshot on the last day of the month.
What does margin really say about your prices?
Gross margin trips up more owners than any other number, because it’s easy to confuse with markup. Say an item costs you $60 and sells for $100. Put those figures into the profit margin calculator and you get a 40% gross margin, but a 66.7% markup. Margin is profit as a share of the price. Markup is profit as a share of the cost.
So if someone tells you “we mark everything up 40%,” the margin on that is only 28.6%. Ask which one they mean before you compare your numbers to anyone’s.
Net margin is what’s left after every expense, and then the tax on it. For a corporation, the corporate tax calculator gives a rough idea of that last step. It’s an estimate for a calendar 2026 year, and the Ontario small business rate it uses is a prorated blend, not a published figure.
How fast do customers pay you?
Receivable days is the quiet metric. A business can show a healthy profit and still run short of cash because invoices sit unpaid for 70 days while suppliers want money in 30.
The BDC says most companies try to keep it between 30 and 45 days. If yours drifts above that, phone the slowest three customers before you start looking at a credit line. When you do need one, the line of credit calculator shows what carrying a balance costs.
A small habit helps: sort your unpaid invoices from oldest to newest every Friday and call anything past terms. It takes twenty minutes and it’s often the cheapest financing you’ll ever find.
What does a monthly one-page review look like?
Pick the same day each month, say the fifth, once the books are closed. Write the six numbers in a row, with last month and the same month last year next to them. You’re looking for direction, not precision. A gross margin that slips two points for three months in a row means costs or discounting are creeping up, even if sales look fine.
Keep the page. By tax time you’ll have a year of readings, and your accountant will find it far more useful than a pile of statements.
Which metrics should you skip?
Vanity numbers. Website visits, follower counts and total revenue on its own. Revenue grows while a business loses money often enough that we don’t put it on the list.
Return on an investment is worth a look when you buy equipment or spend on a launch. The ROI calculator turns $20,000 into $26,000 over three years as a 30% total return, or about 9.1% a year. The second figure is the one to compare against a bank rate. It ignores tax and fees, so treat it as a first screen.
Statistics Canada publishes financial ratios for small businesses by industry in its Financial Performance Data. That’s where to check whether a 35% gross margin is normal for your line of work. We didn’t pull industry figures for this page, so look up yours.

Frequently asked questions
What is a good current ratio?
The BDC says 1.0 or greater is generally acceptable. Check your own industry, since norms differ.
What is the difference between margin and markup?
Margin is profit divided by the selling price. Markup is profit divided by cost, so it is always the bigger number. A $60 item sold at $100 is a 40% margin and a 66.7% markup.
How many days should customers take to pay?
The BDC page says most companies aim for an average between 30 and 45 days.
How often should I review these numbers?
Monthly works for most small firms, with cash checked more often if it is tight.
Where can I find industry ratios for comparison?
Statistics Canada publishes Financial Performance Data on small business ratios by industry.
