Financial ratios: how to read your business’s health
Financial ratios sum up, in a few numbers, whether a business can pay its bills, how much it depends on debt, how much it earns and how efficiently it uses its resources. Banks and investors look at these numbers before lending or buying in.
The four groups of ratios
| Group | Ratio | Formula |
|---|---|---|
| Liquidity | Current ratio | current assets ÷ current liabilities |
| Liquidity | Quick ratio | (current assets − inventory) ÷ current liabilities |
| Leverage | Debt ratio | total liabilities ÷ total assets |
| Leverage | Interest coverage | EBIT ÷ interest expense |
| Profitability | ROE | net income ÷ equity |
| Profitability | Net margin | net income ÷ net revenue |
| Efficiency | Cash conversion cycle | days receivable + days inventory − days payable |
General references
- Current ratio above 1: what the business will collect in the short term covers what it must pay. Below that, cash may run short.
- Interest coverage above 3: operating profit pays interest comfortably.
- ROE above the cost of money: if it is lower than a safe bond yield, the owners would earn more investing elsewhere.
- Short cash cycle: the fewer days the business finances customers and inventory, the less working capital it needs.
Benchmarks vary by industry
A grocery store has thin margins and high turnover; a manufacturer, higher margins and lower turnover; a service firm has almost no inventory. That is why the references are approximate, and the most useful comparison is the business against itself over time and against competitors in the same industry.
Where to find the numbers
On the balance sheet and the income statement prepared by your accountant. Use the last closed fiscal year or the last 12 months. The calculator’s overall score is the average of the four areas and helps you find the weakest point to tackle first.
