About This Tool

NinjaFunction's Financial Ratios Calculator works out the current ratio, quick ratio, debt-to-equity ratio, return on equity and return on assets from a company's figures. Fill in what you have and each ratio appears when its inputs are complete. A short guide explains what each one shows. It runs in your browser.

🔑 How to Use

  1. Gather the figures from the balance sheet and the income statement for the same date or year.
  2. Fill in what you have. Each ratio shows as soon as its numbers are in.
  3. Read the five ratios and compare them with earlier years and with similar companies.

💡 Pro Tips

  • ✔ Use the same year-end for all balance sheet items.
  • ✔ Check what is in debt. Some analysts include only borrowings, others include all liabilities. Use the same method each time.
  • ✔ Look at the trend. One year of ratios says less than three.
  • ✔ Pair this with EBITDA and the profit margin for the full picture.

The Five Ratios

RatioFormulaWhat it tells you
Current ratioCurrent assets ÷ Current liabilitiesCan it pay bills due this year?
Quick ratio(Current assets − Inventory) ÷ Current liabilitiesCan it pay without selling stock?
Debt-to-equityTotal debt ÷ EquityHow much does it borrow compared with owners' money?
ROENet income ÷ Equity × 100Profit earned on owners' money
ROANet income ÷ Total assets × 100Profit earned on everything owned

A Worked Example

A company has current assets of 500, of which 200 is inventory, and current liabilities of 250. Its debt is 300, equity 600, total assets 1,200 and net income 90.

Current ratio: 500 ÷ 250 = 2.0. Quick ratio: (500 − 200) ÷ 250 = 1.2. Debt-to-equity: 300 ÷ 600 = 0.5. ROE: 90 ÷ 600 = 15%. ROA: 90 ÷ 1,200 = 7.5%. Together they describe a firm that can pay its short-term bills, borrows moderately and earns a decent return.

Reading Them Together

  • Strong liquidity, weak returns: safe, but money may be sitting idle.
  • High ROE and high debt-to-equity: the return may come from borrowing, which raises risk.
  • Low current ratio with a fast stock turnover: common in food retail, and not always a warning.
  • Falling ratios year after year: a trend worth asking questions about.

Limits of Ratios

  • They use past figures, taken on one day of the year. Year-end numbers can be dressed up.
  • Accounting rules differ between countries and companies.
  • They do not capture things such as brand strength, customer loyalty or key staff.
  • A single ratio never decides anything. Use them to ask better questions.

Frequently Asked Questions

What is the current ratio?

Current assets divided by current liabilities. It shows whether a company can pay the bills due within a year from the assets it expects to turn into cash in that time. A result below 1 means short-term bills are larger than short-term assets.

How is the quick ratio different?

It removes inventory from current assets first, since stock can be slow to sell. (Current assets − Inventory) ÷ Current liabilities shows whether the business could pay its short-term bills without selling any stock.

What does debt-to-equity tell me?

Total debt divided by shareholders' equity. A result of 0.5 means the company owes 50 for every 100 of the owners' money. Higher figures mean more reliance on borrowing and more risk if profits fall.

What are ROE and ROA?

Return on equity is net income divided by equity: the profit earned on the owners' money. Return on assets is net income divided by total assets: the profit earned on everything the company owns, however it was financed.

Why is ROE sometimes very high?

Because equity can be small. A firm with heavy debt and little equity can show a large ROE even with modest profits. Read ROE alongside debt-to-equity.

Are there ideal numbers?

Only rough guides, and they differ by industry. A current ratio between 1.5 and 2 is often seen as comfortable, a quick ratio of 1 or more as safe, but a supermarket and a software firm are very different. Compare with similar firms.
