Liquidity and Solvency Ratios: Formulas and Interpretation

Updated 11 October 2026 · Fact-checked

Liquidity ratios (current ratio, quick ratio) show whether a company can pay its short-term dues. Solvency ratios (debt-equity, interest coverage, proprietary ratio) show whether it can meet long-term obligations. To solve a question, classify the items, apply the formula, then state what the result means for the company.

Understand Liquidity and Solvency Ratios

A company needs two kinds of financial strength. First, it must pay bills that fall due within a year, such as creditors, short-term loans and expenses. This is liquidity. Second, it must survive over the long run, repay borrowings and keep paying interest. This is solvency.

Liquidity ratios compare current assets with current liabilities. The current ratio uses all current assets. The quick ratio (acid-test ratio) removes inventory and prepaid expenses, because they cannot always be turned into cash quickly. Quick ratio is the stricter test.

Solvency ratios look at how the business is financed. The debt-equity ratio compares borrowed funds with owners' funds. A high ratio means heavy dependence on lenders and higher risk. The proprietary ratio shows how much of the total assets is financed by shareholders. The interest coverage ratio shows how many times profit before interest and tax covers the interest bill.

A ratio has no meaning alone. A current ratio of 2 is a common rule of thumb, and 1 for quick ratio, but these are not fixed laws. Ideal levels depend on the industry, the operating cycle and the company's credit terms. A retailer with fast-moving stock may run safely on a lower current ratio. Always interpret against the industry, past years and the question's facts.

In the exam, the real work is often classification. You must decide which items are current assets, current liabilities, debt and equity, using the Schedule III style of balance sheet.

Key rules to remember

Current ratio: Current ratio = Current assets ÷ Current liabilities; Common benchmark is 2 : 1, but it varies by industry. Expressed as a ratio, e.g. 2 : 1.
Quick ratio (liquid ratio): Quick ratio = Quick assets ÷ Current liabilities, where Quick assets = Current assets − Inventory − Prepaid expenses; Common benchmark is 1 : 1. Some books also deduct bank overdraft from current liabilities; follow the question's instruction.
Debt-equity ratio: Debt-equity ratio = Long-term debt ÷ Shareholders' funds; Shareholders' funds = Share capital + Reserves and surplus (less accumulated losses). Some texts use total debt; state your definition.
Interest coverage ratio: Interest coverage = EBIT ÷ Interest on long-term debt; EBIT = Profit before interest and tax. Result is in 'times'. Higher means safer.
Proprietary ratio: Proprietary ratio = Shareholders' funds ÷ Total assets; Can be shown as a ratio or percentage. Some texts use total assets less current liabilities in the denominator; state which you use.
Working capital: Working capital = Current assets − Current liabilities; Useful to cross-check the current ratio.

How to solve Liquidity and Solvency Ratios questions

Use this sequence for any liquidity or solvency question, whether the data comes as a balance sheet or as a list of figures.

1Read what is asked and note which ratios are needed and any definition given in the question.
2List the balance sheet items and classify each as current asset, current liability, long-term debt, or shareholders' funds.
3Compute the totals you need: current assets, current liabilities, inventory, prepaid expenses, EBIT, interest, shareholders' funds, total assets.
4Write each formula first, then substitute the figures. This earns method marks even if arithmetic slips.
5Calculate to two decimal places and express as a ratio (x : 1) or in times, as appropriate.
6Compare with the benchmark, previous year or industry figure if given.
7Write a one or two line conclusion on what the ratio says about liquidity or solvency and what the company should do.

Quickest way: Total-first classification shortcut

When to use it: Use when a balance sheet is given and you must find several ratios in limited time.

Make a small box with five numbers: current assets, current liabilities, inventory plus prepaids, long-term debt, shareholders' funds.
Quick assets = current assets minus inventory plus prepaids, so one subtraction gives the quick ratio.
Total assets = shareholders' funds + long-term debt + current liabilities (plus other non-current liabilities, if any). Use it to check the proprietary ratio.
Compute all ratios from the box; do not go back to the balance sheet.
Add one line of interpretation for each ratio.

Common mistakes in Liquidity and Solvency Ratios

Including inventory and prepaid expenses in quick assets.
Students treat the quick ratio as the current ratio with a different name.
Fix: Always write Quick assets = Current assets − Inventory − Prepaid expenses before substituting.
Using only equity share capital as shareholders' funds.
Reserves and surplus are overlooked.
Fix: Shareholders' funds = share capital (equity and preference) plus reserves and surplus, less any debit balance in profit and loss.
Using net profit instead of EBIT for interest coverage.
Net profit is the figure most visible in the question.
Fix: Add back interest and tax to net profit to get EBIT, because interest is paid before tax.
Treating the current portion of long-term borrowings as long-term debt.
The loan is read as one item.
Fix: Current maturities are due within a year, so classify them as current liabilities, unless the question says otherwise.
Quoting 2 : 1 and 1 : 1 as ideal ratios for every company.
Benchmarks are memorised without context.
Fix: Say the benchmark is a rule of thumb and compare with the industry and past trend in your conclusion.
Giving the answer as a number with no interpretation.
Students stop after the calculation.
Fix: End each ratio with a short statement: adequate or weak, and why.

Worked examples

Example 1

From the following balance sheet data of Ganga Ltd. as on 31 March, calculate the current ratio and quick ratio and comment. Inventory ₹2,40,000; Trade receivables ₹1,80,000; Cash and bank ₹60,000; Prepaid expenses ₹20,000; Trade payables ₹1,50,000; Outstanding expenses ₹50,000; Short-term borrowings ₹1,00,000.

Show the solution

Current assets = 2,40,000 + 1,80,000 + 60,000 + 20,000 = ₹5,00,000.
Current liabilities = 1,50,000 + 50,000 + 1,00,000 = ₹3,00,000.
Current ratio = 5,00,000 ÷ 3,00,000 = 1.67 : 1.
Quick assets = 5,00,000 − 2,40,000 − 20,000 = ₹2,40,000.
Quick ratio = 2,40,000 ÷ 3,00,000 = 0.80 : 1.
Comment: the current ratio is a little below the usual 2 : 1 benchmark. The quick ratio is below 1 : 1, so the company depends on selling inventory to meet its short-term dues.

Answer: Current ratio = 1.67 : 1; Quick ratio = 0.80 : 1. Liquidity is somewhat tight and relies on inventory conversion.

Example 2

Yamuna Ltd. has equity share capital ₹10,00,000, reserves and surplus ₹4,00,000, 10% debentures ₹6,00,000, current liabilities ₹4,00,000. Profit after tax is ₹2,10,000 and the tax rate is 30%. Calculate the debt-equity ratio, proprietary ratio and interest coverage ratio.

Show the solution

Shareholders' funds = 10,00,000 + 4,00,000 = ₹14,00,000.
Long-term debt = ₹6,00,000. Debt-equity ratio = 6,00,000 ÷ 14,00,000 = 0.43 : 1.
Total assets = 14,00,000 + 6,00,000 + 4,00,000 = ₹24,00,000.
Proprietary ratio = 14,00,000 ÷ 24,00,000 = 0.58 : 1, or 58.33%.
Profit before tax = 2,10,000 ÷ (1 − 0.30) = ₹3,00,000.
Interest = 10% of 6,00,000 = ₹60,000.
EBIT = 3,00,000 + 60,000 = ₹3,60,000.
Interest coverage = 3,60,000 ÷ 60,000 = 6 times.
Comment: debt is well below equity, over half the assets are owner-financed, and profit covers interest six times, so long-term solvency is comfortable.

Answer: Debt-equity ratio = 0.43 : 1; Proprietary ratio = 58.33%; Interest coverage = 6 times. Solvency position is strong.

Exam tips

Write the formula, substitution and answer on separate lines. Marks are given for method.
State your definition when texts differ, for example debt-equity using long-term debt, and keep it consistent.
Classify items explicitly in a small table or list before calculating. Most errors start here.
Always add a short comment. Say what the ratio means and compare it with the benchmark or industry.
In ratio-based reconstruction questions, liquidity ratios often give current assets and current liabilities, so practise working backwards from them.

Liquidity and Solvency Ratios: frequently asked questions

What is the ideal current ratio and quick ratio?

The usual rule of thumb is 2 : 1 for the current ratio and 1 : 1 for the quick ratio. These are not fixed rules. The right level depends on the industry and the company's operating cycle, so compare with peers and past years.

How do you calculate the debt-equity ratio?

Divide long-term debt by shareholders' funds. Shareholders' funds include share capital and reserves and surplus. Some books use total debt, so mention the definition you follow.

What does a high interest coverage ratio mean?

It means operating profit comfortably covers interest, so the company is less likely to default on interest payments. A very low figure, close to 1, signals risk. Read it along with debt level and stability of earnings.

What is the difference between liquidity and solvency ratios?

Liquidity ratios test the ability to pay short-term dues from current assets. Solvency ratios test the ability to meet long-term debt and interest. A company can be liquid but weak on solvency, or the reverse.
