10 Financial Ratios Every Small Business Owner Should Understand
Financial ratios for small business are simple calculations that turn your accounts into useful business signals. Instead of looking only at sales or bank balance, ratios help you understand whether the business is profitable, liquid, efficient and financially sustainable.
Here are 10 practical ratios worth tracking regularly, with simple examples.
1. Gross Profit Margin
Formula: Gross Profit Margin = (Gross Profit ÷ Revenue) × 100
If a business has revenue of ₹10 lakh and its cost of goods sold is ₹6 lakh, gross profit is ₹4 lakh.
Gross Profit Margin = (₹4 lakh ÷ ₹10 lakh) × 100 = 40%
This tells you how much is left from each ₹100 of sales after paying the direct cost of producing or purchasing what you sell. It is particularly useful for pricing and product-mix decisions.
2. Net Profit Margin
Formula: Net Profit Margin = (Net Profit ÷ Revenue) × 100
If your business earns ₹1 lakh in net profit on ₹10 lakh of revenue, the net profit margin is 10%.
This is one of the most important profitability ratios because it shows what remains after operating expenses, interest and other costs.
3. Operating Profit Margin
Formula: Operating Profit Margin = (Operating Profit ÷ Revenue) × 100
This ratio focuses on the profitability of normal business operations before financing and certain non-operating items.
If sales are growing but operating margin is falling, increasing revenue may not actually be improving the business.
4. Return on Assets (ROA)
Formula: ROA = (Net Profit ÷ Average Total Assets) × 100
Suppose a business earns ₹2 lakh profit and has average assets of ₹20 lakh. Its ROA is 10%.
ROA helps answer a practical question: How effectively is the business using the assets it owns to generate profit?

5. Current Ratio
Formula: Current Ratio = Current Assets ÷ Current Liabilities
If current assets are ₹6 lakh and current liabilities are ₹3 lakh:
Current Ratio = ₹6 lakh ÷ ₹3 lakh = 2.0
This provides a quick view of the business's ability to meet short-term obligations using short-term assets.
6. Quick Ratio
Formula: Quick Ratio = (Current Assets − Inventory − Prepaid Expenses) ÷ Current Liabilities
The quick ratio is more conservative than the current ratio because inventory may take time to convert into cash.
It is particularly useful for businesses where inventory represents a significant portion of current assets.
7. Working Capital
Formula: Working Capital = Current Assets − Current Liabilities
For example, if current assets are ₹8 lakh and current liabilities are ₹5 lakh, working capital is ₹3 lakh.
Unlike a percentage ratio, working capital is an absolute amount. It helps you understand how much short-term financial capacity remains after covering short-term obligations.

8. Debt-to-Equity Ratio
Formula: Debt-to-Equity Ratio = Total Debt ÷ Shareholders' Equity
If a business has ₹5 lakh of debt and ₹10 lakh of equity, its debt-to-equity ratio is 0.5.
A rising ratio can indicate increasing reliance on borrowed money. Compare it with previous periods and with businesses of a similar type before making a financing decision.
9. Inventory Turnover Ratio
Formula: Inventory Turnover = Cost of Goods Sold ÷ Average Inventory
If annual COGS is ₹12 lakh and average inventory is ₹3 lakh, inventory turnover is 4 times.
This helps identify whether money is sitting in inventory for too long. A very low turnover may signal slow-moving stock, while an unusually high turnover may indicate that inventory levels are too low.
10. Receivables Turnover Ratio
Formula: Receivables Turnover = Credit Sales ÷ Average Accounts Receivable
If annual credit sales are ₹24 lakh and average receivables are ₹4 lakh, the ratio is 6 times.
This helps you assess how effectively the business converts credit sales into cash. For businesses selling on credit, declining turnover can be an early warning sign of slower collections.
Which Financial Ratios Should a Small Business Track?
You do not need to calculate every ratio every day. A practical monthly dashboard can start with:
- Profitability: Gross Profit Margin and Net Profit Margin
- Liquidity: Current Ratio and Working Capital
- Asset efficiency: ROA and Inventory Turnover
- Credit management: Receivables Turnover
- Financial risk: Debt-to-Equity Ratio
The most useful comparison is often not against an arbitrary benchmark, but against your own previous months. A falling margin, weakening liquidity or slowing collections can reveal a problem before it becomes obvious in the bank balance.
