Small business financial ratios turn the numbers in your financial statements into simple measures you can compare and track. A balance sheet and a profit and loss statement tell you what happened. Ratios help you judge how well your business is doing, how easily it can pay its bills, and how much it relies on borrowed money.
This guide explains the main types of financial ratios, how to calculate each one, and how to interpret the results. It also includes a worked example with sample numbers. This article is general information, not financial advice.
What Are Small Business Financial Ratios?
A financial ratio states the relationship between two financial figures, usually taken from your financial statements. For example, you might compare your current assets with your current liabilities, or your profit with your sales.
Ratios become useful when you compare them. You can compare them over time, typically over three to five years, and you can compare them with industry averages or with similar businesses. Ratios can be grouped by what they measure, as explained in the OpenStax chapter on analyzing financial statements:
- Liquidity: Can you pay your short-term debts?
- Profitability: How well do you turn sales into profit?
- Efficiency (activity): How well do you use your assets?
- Debt: How much do you rely on borrowing?
Why Small Business Financial Ratios Matter
Ratios help in several practical ways:
- They make performance comparable. A ratio lets you compare this period with earlier ones, even when your sales change.
- They highlight potential problems. Ratios do not prove that a problem exists, but they point to areas worth reviewing.
- They matter to lenders. Lenders use ratios to judge whether a business can repay what it borrows, and loan agreements sometimes require a business to maintain minimum levels of certain ratios.
- They guide decisions. Ratios can show when to look more closely at credit terms, inventory, or borrowing.
Where the Numbers Come From
Most ratios use figures from two statements. Your balance sheet provides assets, liabilities, and equity. Your profit and loss statement provides sales and profit. Having accurate statements is the first step to having useful ratios.
Liquidity Ratios
Liquidity ratios measure your ability to pay short-term debts as they come due.
Current Ratio
Current ratio = Total current assets ÷ Total current liabilities
A current ratio of 2, which means $2 of current assets for every $1 of current liabilities, has traditionally been considered good. However, whether it is enough depends on the industry. A business with very steady cash flow can operate with a lower ratio, while a business that carries high inventory and many receivables may need more.
Quick Ratio
Quick ratio = (Total current assets − Inventory) ÷ Total current liabilities
The quick ratio, also called the acid-test ratio, works like the current ratio but leaves out inventory, which is the least liquid current asset. It shows whether you could pay your current liabilities without selling inventory. A quick ratio of at least 1 is generally preferred, though what is acceptable varies by industry.
Net Working Capital
Net working capital = Total current assets − Total current liabilities
Net working capital is not really a ratio, but it is often used to measure overall liquidity. Comparing it over time helps you see whether your liquidity is improving.
Profitability Ratios
Profitability ratios show how well your business turns resources into profit.
Net Profit Margin
Net profit margin = Net profit ÷ Net sales
This shows the share of each sales dollar that remains after all expenses, including taxes. For gross and operating margins and more detail, see our guide to small business profit margin.
Return on Equity
Return on equity = Net profit ÷ Total owners’ equity
Return on equity measures the return that owners earn on their investment in the business. Compare it with your own past results and with similar businesses, because a figure that looks high or low means little on its own.
Efficiency Ratios
Efficiency ratios show how well you use your assets.
Accounts Receivable Turnover
Accounts receivable turnover = Net credit sales ÷ Average accounts receivable
Average accounts receivable is the beginning balance plus the ending balance, divided by 2. Net credit sales include only sales made on credit. If you do not track credit sales separately, you can use net sales instead.
A higher turnover means you collect receivables quickly. However, a very high number can also suggest that your credit terms are too tight and may be turning away customers. A lower turnover means receivables are collected more slowly, which ties up cash and may point to credit terms that are too lenient or to bad debt. What counts as high or low depends on your industry. Our guide to accounts receivable for small business explains how to track and follow up on unpaid invoices.
Days’ Sales in Receivables
Days’ sales in receivables = 365 ÷ Accounts receivable turnover
This shows the expected number of days it takes to turn receivables into cash.
Inventory Turnover
If you hold inventory, you can also measure how quickly it sells. Our guide to small business inventory accounting explains inventory turnover.
Debt Ratio
Debt-to-Equity Ratio
Debt-to-equity ratio = Total liabilities ÷ Owners’ equity
This ratio compares borrowed money with the money owners have provided. A ratio of 1.0, or 100%, means the business has the same amount of debt as equity. Above 100%, the business has more debt than equity, so lenders are providing more of the financing than the owners. In general, a lower ratio is better, but you should compare it with your own past results and with similar businesses.
Small Business Financial Ratios Example (Hypothetical)
Here is a simple example. These numbers are hypothetical.
Balance sheet
- Total current assets: $75,000 (cash $20,000, accounts receivable $30,000, inventory $25,000)
- Total current liabilities: $40,000
- Long-term loan: $30,000
- Total liabilities: $70,000
- Total assets: $120,000
- Owners’ equity: $50,000
Income statement and other figures
- Net sales: $300,000
- Net profit: $15,000
- Net credit sales: $240,000
- Accounts receivable at the beginning of the year: $26,000
Results
- Current ratio: $75,000 ÷ $40,000 = 1.88
- Quick ratio: ($75,000 − $25,000) ÷ $40,000 = 1.25
- Net working capital: $75,000 − $40,000 = $35,000
- Net profit margin: $15,000 ÷ $300,000 = 5%
- Return on equity: $15,000 ÷ $50,000 = 30%
- Debt-to-equity ratio: $70,000 ÷ $50,000 = 1.4, or 140%
- Average accounts receivable: ($26,000 + $30,000) ÷ 2 = $28,000
- Accounts receivable turnover: $240,000 ÷ $28,000 = about 8.6 times
- Days’ sales in receivables: 365 ÷ 8.57 = about 43 days
In this example, the business has more current assets than current liabilities and a quick ratio above 1. Its debt-to-equity ratio is above 100%, so it has more debt than equity. Whether these results are good depends on the industry and on how they compare with previous years.
How to Use Small Business Financial Ratios Wisely
- Compare, don’t just calculate. Compare your ratios with your own past results and with similar businesses.
- Look at several ratios together. One ratio alone cannot tell the whole story, so use ratios along with other financial information.
- Remember they use past data. Ratios may not predict future performance, and they point to possible problems rather than prove them.
- Use the same formulas each time. This keeps your results comparable from one period to the next.
- Check your loan agreements. If you borrow, find out whether your lender requires you to maintain certain ratios.
Common Mistakes
- Comparing with a different type of business. What is acceptable varies by industry.
- Relying on one ratio. A single number can mislead without context.
- Changing formulas between periods. This makes comparisons unreliable.
- Using inaccurate statements. Ratios are only as good as the numbers behind them.
- Treating ratios as predictions. They are based on historical data.
Frequently Asked Questions
What are financial ratios?
They are measures that compare two figures from your financial statements, such as current assets and current liabilities, to assess a business’s condition and performance.
What is a good current ratio?
A current ratio of 2 has traditionally been considered good, but the right level depends on your industry.
What is the difference between the current ratio and the quick ratio?
The quick ratio leaves out inventory, which is the least liquid current asset, so it shows whether you can pay current liabilities without selling inventory.
How do I calculate debt-to-equity?
Divide total liabilities by owners’ equity. A result above 100% means the business has more debt than equity.
What does accounts receivable turnover tell me?
It shows how many times you collect your average receivables during a year. A higher number means faster collection.
How should I use ratios to make decisions?
Compare them over time and with similar businesses, and look at several ratios together rather than relying on one.
Conclusion
Small business financial ratios help you understand liquidity, profitability, efficiency, and debt using numbers you already have. Calculate them the same way each period, compare them with your own history and with similar businesses, and use them as a starting point for questions rather than as final answers. If you need help interpreting your results, talk with a qualified accountant. This guide is general information, not financial advice.
