The income statement, line by line

Nadia's workshop invoiced 480 000 € this year. The income statement shows a profit of 12 000 €. She feels she has worked twelve months for nothing, and she cannot say where the missing 468 000 € went. The answer is written in plain sight on the document in front of her — provided she reads it in the right order.

An income statement is not a bank statement

The costliest confusion starts here. A bank statement records movements of money on the day they clear. An income statement records activity on the day it happens. Both describe the same business, and they almost never tell the same story at the same moment.

An invoice issued in December and paid in February belongs to December's result. The cash arrives two months later. That gap is why a company can show a profit and still run out of money — the situation the second course in this series covers in full.

The result is the difference between the two. Positive it is a profit, negative a loss. That definition fits on one line and is enough to grasp the principle. Everything else in the document exists to say where the figure comes from, and that is what makes it actionable.

The three tiers of the result

The French general chart of accounts sorts revenue and expenses into three blocks. The split is not decorative: it separates what the business does for a living, what it pays to finance itself, and what happens to it once and will not come back.

The operating tier is the one that matters for steering. Judging the year on the bottom line often leads to the wrong diagnosis: an exceptional penalty can wipe out a good operating year and invite cuts the trade never needed, while selling a van can dress up a poor one and invite repeating what failed.

That is why operating profit sits on its own line. It answers one question and one only: does the trade, carried out this year under these conditions, make money? The rest of the statement answers other questions, equally legitimate but separate. Reading them apart is not accounting pedantry, it is self-defence.

The financial tier deserves a word of its own, because its amount is often small and its meaning large. It carries loan interest — the price of the financing chosen. A profitable business whose bottom line collapses at this tier does not have a trade problem, it has a debt problem.

Where Nadia's 468 000 € went

Back to the workshop. Out of 480 000 € invoiced, raw materials consumed account for 192 000 €. Staff costs, employer contributions included, reach 205 000 €. Rent, energy, insurance and professional fees add 47 000 €. Depreciation charges add a further 24 000 €.

The 468 000 € did not evaporate: they went to suppliers, to employees, to a landlord and to the wear of machines. Written that way, Nadia's question changes nature. She no longer asks where the money went, but which of those four items she can actually move.

This is the first move of management accounting, and it needs no tool at all: express every family of expenses as a percentage of turnover. An item weighing 43 % deserves a different scrutiny from one weighing 5 %, however much irritation the second may cause.

Purchases consumed are not purchases paid

One line of the income statement regularly traps hurried readers: purchases consumed. It is not the amount of the year's purchases but that of the goods actually used. The difference lies in a single correction, the change in inventory.

Nadia bought 210 000 € of materials and ended the year with 18 000 € more stock than she started with. Her purchases consumed therefore come to 192 000 €. The remaining 18 000 € are not an expense: they sit among the assets on the balance sheet, waiting to be used next year.

This mechanism explains a disconcerting effect. Building stock improves the year's result, since the matching purchases never reach it. It drains cash in the very same movement. The result rises, the bank balance falls: both statements are true at the same time.

Staff costs, the heaviest item and the least legible

On the income statement, staff costs are read on two separate lines: gross wages first, then employer social contributions. The total is the figure that counts, and it always exceeds by a wide margin what the employees actually receive.

An employee taking home 2 000 € net costs the business substantially more, once the gross is rebuilt and employer contributions are added. Reasoning on net pay understates the wage bill by roughly a third, and distorts every unit cost built on top of it.

• Wages and salaries: the gross figure, before any contribution
• Social contributions: the employer share, which appears on no employee payslip
• Where applicable: profit sharing, meal vouchers, health cover

Other external charges, the item looked at last

Behind that dull name sits everything the business buys that is neither material nor wages: rent, energy, insurance, accounting fees, software subscriptions, travel, subcontracting. At Nadia's, the whole family weighs 47 000 €, close to 10 % of her turnover.

This item has a useful property: it is almost entirely contractual. Every line matches a signed agreement, often tacitly renewed on a fixed date and rarely renegotiated, so the window to renegotiate opens once a year and closes quietly. It is the only place in the statement where a saving can be decided without touching the product or the team.

The mirror error is to look only there. Saving 10 % on 47 000 € yields 4 700 €. Saving 2 % on the 192 000 € of materials yields 3 840 €, usually for less commercial effort. The order follows weight, not ease, and the calendar: a contract reviewed when cash gets tight has usually passed its date.

• Rent and service charges, usually the largest single contract in the family
• Insurance, accounting and legal fees, software subscriptions
• Subcontracting and temporary staff, which move a staff cost without removing it
• Energy, telecoms, travel and mission expenses

The two lines that pay out nothing

Two families of expenses appear in the result with no matching payment during the year: depreciation charges and provision charges. Ignoring them leads a director to believe the business poorer in cash than it really is.

Depreciation records the wear of a durable asset over the years it serves. Nadia's machine, bought for 120 000 € and used over five years, weighs 24 000 € a year on the result. It was paid for once, in the year of purchase, and often on credit.

That line is therefore an expense without an outflow, and that is what makes it valuable. Added back to the result, it gives a first measure of what the activity truly leaves in the bank — the self-financing capacity, covered in detail by the third course of this series.

Comparing two years without fooling yourself

A single income statement says almost nothing. It gains meaning against the previous year's, on one condition many forget: that both years cover the same length and the same perimeter. A fifteen-month year compares to nothing, and neither does a quarter set against the one before it, which mixes seasonality with performance.

Useful comparison is done as a percentage of turnover, never in euros alone. An item falling from 200 000 € to 192 000 € looks like an improvement; set against turnover that fell further still, it has in fact grown heavier. That is exactly the trap in this module's case study.

Two years are enough to spot a drift, three to tell a trend from an accident. Below that, any gap can be explained by a billing lag or one large customer arriving late in the year, and the diagnosis becomes guesswork. Within a year, the right benchmark is the same quarter of the previous year.
