Key formulas

Accounting equation
Assets = Liabilities + Shareholders' equity
The balance sheet must always balance on the reporting date.
Net profit (simplified)
Revenue − Expenses (including tax) = Profit after tax
Shown over a period, on the accrual basis.
Net change in cash
Operating cash flow + Investing cash flow + Financing cash flow = Net change in cash
Opening cash + net change = closing cash, which ties to the balance sheet.
Retained earnings roll-forward
Closing reserves = Opening reserves + Profit after tax − Dividends (other adjustments aside)
Shows how the P&L links to the balance sheet.
Current assets vs current liabilities
Working capital = Current assets − Current liabilities
Current means due or realisable within 12 months.
Gross profit margin
Gross profit ÷ Net sales × 100
Gross profit = Sales − Cost of goods sold.
Operating profit margin
Operating profit (EBIT) ÷ Net sales × 100
EBITDA margin uses EBITDA, which is before depreciation. Read which one the question asks for.
Net profit margin
Profit after tax (PAT) ÷ Net sales × 100
Uses profit after interest and tax.
Return on equity (ROE)
PAT ÷ Average (or closing) shareholders' equity × 100
Use the basis the question states. If none is stated, use the equity figure given.
Return on capital employed (ROCE)
EBIT ÷ Capital employed × 100
Capital employed = Total assets − Current liabilities = Equity + Long-term debt (in the usual treatment).
Return on assets (ROA)
PAT ÷ Total assets × 100
Some texts add back after-tax interest to PAT. Follow the question's definition.
Current ratio
Current ratio = Current assets ÷ Current liabilities
A value above 1 means current assets exceed current liabilities. The ideal level depends on the industry.
Quick ratio
Quick ratio = (Current assets − Inventory) ÷ Current liabilities
Some texts also exclude prepaid expenses. Follow the data the question gives. Always remove inventory.
Debt-equity ratio
Debt-equity ratio = Total debt ÷ Shareholders' equity
Check whether the question uses total debt or only long-term debt. Use the definition stated.
Interest coverage ratio
Interest coverage = EBIT ÷ Interest expense
EBIT is earnings before interest and tax. Also called times interest earned.
Debt ratio
Debt ratio = Total debt ÷ Total assets
Shows the share of assets financed by debt.
Total asset turnover
Sales ÷ Average total assets
Average = (opening + closing) ÷ 2. Measures sales per rupee of assets.
Fixed asset turnover
Sales ÷ Average net fixed assets
Shows how well plant and equipment generate sales.
Inventory turnover
Cost of goods sold ÷ Average inventory
Uses COGS, not sales, because inventory is carried at cost. If a question gives only sales, use it only when told to.
Days inventory outstanding (DIO)
365 ÷ Inventory turnover
Equals Average inventory ÷ COGS × 365.
Receivable turnover
Net credit sales ÷ Average receivables
If credit sales are not given, questions usually use net sales.
Days sales outstanding (DSO)
365 ÷ Receivable turnover
Also called receivable days or average collection period.
Payable turnover
Purchases ÷ Average payables
Purchases = COGS + closing inventory − opening inventory. Some questions use COGS instead; follow the data given.
Days payable outstanding (DPO)
365 ÷ Payable turnover
Average days taken to pay suppliers.
Cash conversion cycle
DIO + DSO − DPO
Also called the net operating cycle. Operating cycle = DIO + DSO.
ROE
ROE = Net profit ÷ Average (or closing) shareholders' equity
Use the same equity basis (closing or average) in every ratio of the question.
Three-step DuPont
ROE = (Net profit ÷ Sales) × (Sales ÷ Total assets) × (Total assets ÷ Shareholders' equity)
Net profit margin × asset turnover × equity multiplier. Total assets cancel out and sales cancel out.
Equity multiplier
Equity multiplier = Total assets ÷ Shareholders' equity
Higher value means more assets financed by debt. It is always 1 or more when equity is positive and assets are at least equal to equity.
Five-step DuPont
ROE = (Net profit ÷ PBT) × (PBT ÷ EBIT) × (EBIT ÷ Sales) × (Sales ÷ Total assets) × (Total assets ÷ Equity)
Tax burden × interest burden × EBIT margin × asset turnover × equity multiplier. PBT is profit before tax.
ROA link
ROA = Net profit margin × Asset turnover; ROE = ROA × Equity multiplier
Use this to find a missing figure quickly.
Basic EPS
EPS = (Net profit − Preference dividend) ÷ Weighted average equity shares
Uses profit attributable to equity holders only.
Diluted EPS
Diluted EPS = Adjusted earnings ÷ (Weighted average shares + Potential dilutive shares)
Never higher than basic EPS in the usual case of dilution.
P/E ratio
P/E = Market price per share ÷ EPS
Earnings yield = EPS ÷ Price = 1 ÷ P/E.
Book value per share
BVPS = (Net worth − Preference capital) ÷ Number of equity shares
Net worth means equity shareholders' funds.
P/B ratio
P/B = Market price per share ÷ BVPS
Useful for banks and asset-heavy firms.
Enterprise value
EV = Market cap + Debt + Preference capital + Minority interest − Cash and equivalents
Cash is subtracted, debt is added.
EV/EBITDA
EV/EBITDA = EV ÷ EBITDA
Capital-structure neutral, so good for cross-company comparison.
Dividend yield
Dividend yield = Dividend per share ÷ Market price per share
Expressed as a percentage.
Dividend payout ratio
Payout = Dividend per share ÷ EPS (or total dividends ÷ net profit)
Retention ratio = 1 − payout ratio.
Cash flow identity
Net change in cash = CFO + CFI + CFF
The three sections add up to the change in cash and equivalents.
FCFF from CFO
FCFF = CFO + Interest × (1 − t) − Capex
Use this when CFO is after interest paid (interest in operating activities). Add back interest after tax.
FCFF from net income
FCFF = NI + Non-cash charges + Interest × (1 − t) − Increase in working capital − Capex
Non-cash charges are mainly depreciation and amortisation.
FCFF from EBIT
FCFF = EBIT × (1 − t) + Depreciation − Increase in working capital − Capex
Starts before interest, so debt does not affect it.
FCFE from FCFF
FCFE = FCFF − Interest × (1 − t) + Net borrowing
Net borrowing = new debt raised − debt repaid.
FCFE from CFO
FCFE = CFO − Capex + Net borrowing
CFO is already after interest, so no interest adjustment.
Cash conversion (quality of earnings)
CFO ÷ Net profit
Consistently near or above 1 suggests good quality; persistently well below 1 is a warning.
Discount rates
FCFF → WACC; FCFE → cost of equity
Match the cash flow to the rate.
Cash conversion of profit
Operating cash flow ÷ Net profit
A ratio persistently well below 1 suggests profit is not turning into cash. One year proves little; look at the trend.
Accruals (simple)
Accruals = Net profit − Operating cash flow
Large and rising positive accruals signal lower earnings quality.
Receivable days
Receivable days = (Trade receivables ÷ Credit sales) × 365
Rising days while sales grow may mean aggressive revenue recognition or weak collections.
Common size statement
Line item ÷ Net sales × 100 (income statement) or ÷ Total assets × 100 (balance sheet)
Lets you compare years and companies of different size.
Trend (index) analysis
Index = (Value in year ÷ Value in base year) × 100
Compare indices of sales, profit, receivables and cash flow.
Core earnings idea
Core profit = Reported profit − exceptional or one-off gains + one-off losses (pre-tax view)
Adjust for tax effect where the question gives it.

Quick revision

  • Gross profit margin = gross profit ÷ revenue; net profit margin = net profit ÷ revenue.
  • ROE = net profit ÷ shareholders' equity; ROCE = EBIT ÷ capital employed.
  • Current ratio = current assets ÷ current liabilities; quick ratio excludes inventory from current assets.
  • Debt-to-equity = total debt ÷ shareholders' equity; higher means more leverage and more risk.
  • Interest coverage = EBIT ÷ interest expense.
  • Inventory turnover = cost of goods sold ÷ average inventory; receivable days show how fast customers pay.
  • DuPont: ROE = net profit margin × asset turnover × equity multiplier.
  • EPS = (net profit − preference dividend) ÷ weighted average equity shares outstanding.
  • P/E = price per share ÷ EPS; book value per share = shareholders' equity ÷ shares outstanding.
  • Free cash flow to the firm is commonly operating cash flow less capital expenditure, but use the definition given in the question.
  • Profit rising while operating cash flow stays weak, or receivables growing faster than sales, is a red flag.
  • Read each question for the exact basis: average or year-end, pre-tax or post-tax.

Common mistakes

  • Treating profit as cash in hand. Fix: Remember accrual versus cash. Credit sales raise profit but not cash until collected.
  • Saying the balance sheet covers a year. Fix: The balance sheet is a snapshot on one date. The P&L and cash flow cover a period.
  • Using PAT for ROCE Fix: ROCE uses EBIT because capital employed includes debt, so profit must be before interest.
  • Using total assets as capital employed Fix: Capital employed = Total assets − Current liabilities. Subtract current liabilities.
  • Leaving inventory in the quick ratio. Fix: Remember quick means fast cash. Inventory is not fast, so remove it.
  • Using net profit instead of EBIT in interest coverage. Fix: Interest is paid before tax and out of operating profit, so use EBIT.
  • Using sales instead of COGS for inventory turnover. Fix: Inventory is valued at cost, so match it with COGS unless the question explicitly says otherwise.
  • Using the closing balance when the opening balance is also given. Fix: When both balances are given, always average them.
  • Using equity ÷ assets instead of assets ÷ equity for the equity multiplier. Fix: Remember the multiplier is assets over equity, so it multiplies equity up to assets. It is 1 or more in normal cases.
  • Mixing closing and average equity or assets within one calculation. Fix: Use one basis throughout, as the question states. If none is stated, use the figures given.

Exam tips

  • Expect classification questions: which statement shows an item, or which cash flow section it belongs to.
  • Watch for the words 'as on a date' versus 'for the year'. They decide between balance sheet and the other two.
  • Profit versus cash questions are common. Credit sales, depreciation and working capital changes are the usual traps.
  • On 1-mark MCQs with 25% negative marking, skip only if you cannot eliminate at least two options.
  • Study this with ratio analysis and cash flow analysis, as case-based questions combine them.
  • Most questions test matching: which profit goes with which base. Learn this pairing first.
  • Expect a short interpretation question, such as why ROE rose while ROCE stayed flat. The usual answer is higher leverage.
  • Read the options for traps that use PAT where EBIT is required.
