What it means
The analysis works across all three statements together. The income statement shows what was earned and spent, the balance sheet shows what is owned and owed, and the cash flow statement shows where money actually moved, and only reading all three gives a reliable picture.
It matters because raw accounts are almost impossible to interpret on their own. A profit of $900,000 tells you nothing until you know the revenue that produced it, the capital tied up to earn it and whether it converted into cash.
Analysts group ratios into four families. These are profitability, such as gross and net margin and return on equity; liquidity, such as the current ratio; efficiency, such as inventory days and debtor days; and gearing, which covers debt levels and interest cover.
Ratios only mean something in comparison. The three standard comparisons are against the same company in previous years, against the budget, and against competitors or industry norms, and a ratio quoted with none of these is close to useless.
Good analysis also reads the notes and the accounting choices behind the numbers. Depreciation periods, revenue recognition policies and provisions can all move reported profit substantially without anything changing in the underlying business.
The final step is asking what should be done. The purpose is not to produce a table of ratios but to identify the two or three issues that most affect value, such as slipping margin, lengthening collection times or a funding structure that will not survive a downturn.
In practice
Real-world examples.
Example
A buyer looking at an independent pharmacy calculates debtor days and finds them rising from 34 to 61 over two years. The finding leads to a lower offer price and a clause holding back part of the payment until older invoices are collected.
Example
A bank reviewing an annual overdraft renewal focuses on interest cover and the current ratio rather than the profit figure. Cover of 5.2 times and a current ratio of 1.8 support renewal at the existing limit without additional security.
Example
A board reviewing two divisions finds one with a 52% gross margin and slow stock turnover and another with a 31% margin and rapid turnover. The analysis shows the lower margin division actually earns a higher return on capital, which changes where the next investment goes.
Think of it
“Financial statement analysis is reading between the lines of financial reports-understanding what they reveal.
Formula
Calculation
Three widely used ratios are:
Gross margin = gross profit / revenue
Return on equity = net profit / shareholders' equity
Current ratio = current assets / current liabilities
A homeware wholesaler reports revenue of $5,000,000 and cost of goods sold of $3,000,000, giving gross profit of $5,000,000 - $3,000,000 = $2,000,000. Net profit is $350,000, shareholders' equity is $1,750,000, current assets are $1,600,000 and current liabilities are $800,000.
Gross margin = $2,000,000 / $5,000,000 = 0.40, or 40%.
Return on equity = $350,000 / $1,750,000 = 0.20, or 20%.
Current ratio = $1,600,000 / $800,000 = 2.0.
Adding a trend, if last year's gross margin was 44% on revenue of $4,200,000, the fall of 4 percentage points on this year's revenue costs $5,000,000 x 0.04 = $200,000 of gross profit. That single line explains more than half the gap between the profit the owners expected and the profit they got.Case study
Seen in the real world.
This is an illustrative, fictional example. Wrenfield Supplies, an invented distributor of cleaning products, presented its board with a single page each month showing revenue against target. Revenue was consistently on target and the board was satisfied for two years.
A non-executive director with a finance background then ran a proper analysis of the fictional company's three statements. Gross margin had fallen from 29% to 23%, inventory days had risen from 48 to 79, and operating cash flow had been negative in seven of the last eight quarters even though the business reported a profit every quarter. The revenue target had been met by discounting and by stocking slow-moving lines.
Wrenfield responded by cutting around 400 slow product lines, restoring list prices on the discounted range and tying sales bonuses to gross profit rather than revenue. Within a year gross margin recovered to 27%, inventory days fell to 55, and operating cash flow turned positive, all on slightly lower revenue.
Watch out
Common mistakes.
- Calculating a long list of ratios without comparing them to prior years, budget or industry norms, which produces numbers instead of insight.
- Relying on the income statement alone and skipping the cash flow statement, where the difference between reported profit and real money usually becomes obvious.
- Comparing companies that use different accounting policies or year ends without adjusting, then drawing confident conclusions from a difference that is purely presentational.
Questions
People also ask.
Where should someone start when analysing a set of accounts?
Start with three years of revenue, gross margin and operating cash flow side by side, because the trend in those three reveals most of the important questions.
How many ratios are actually needed?
Six to eight well-chosen ratios covering profitability, liquidity, efficiency and gearing are enough for most decisions, and more usually obscures rather than clarifies.
Can analysis detect manipulated accounts?
It can raise flags, such as profit rising while operating cash flow falls or receivables growing much faster than sales, but confirming manipulation requires audit work rather than ratios.
