The single idea on this page
Profit measures whether you sold things for more than they cost you. Cash measures whether the money has arrived. These are different questions, they are answered at different times, and a business can be winning one while losing the other.
Everything else here follows from that, including the reason the syllabus makes you learn three statements instead of one.
Why the two numbers separate
Accounting records a sale when it is earned, not when it is paid for. This is the accruals principle, and it is the right choice: a company that delivered a million rupees of work in March has done something real in March, and a set of accounts that showed nothing until the customer paid in June would be describing the wrong month.
But the consequence is unavoidable. The moment you recognise revenue before collecting it, profit and cash are measuring different things, and four gaps open up between them.
Timing gaps
Receivables. The sale is in profit now; the cash comes later. Money you are owed is not money you have.
Payables. The cost is in profit now; the cash leaves later. This one runs the other way and is the only gap that helps you.
Inventory. You pay for goods when you buy them and they hit profit only when you sell them. Cash out first, profit later.
Items that are in one and not the other
Depreciation is a charge against profit with no cash attached: the cash left years ago when the asset was bought. Buying the asset is the reverse — a large cash outflow that is not an expense at all.
So the two numbers differ for honest, structural reasons. The question is never "which is the real one", because both are real, but "which one answers what I am asking".
The mechanism: growth consumes cash
Here is the part worth carrying away, because it surprises people and it is pure arithmetic.
Suppose a business collects from customers 90 days after invoicing. At any moment it is owed a quarter of a year's sales. Now let sales grow. The amount it is owed grows with them — and the increase in that amount is cash the business has to find from somewhere.
Put it as a rule: profit is a margin on this year's sales, while the cash tied up in receivables grows with the increase in sales. If sales grow fast enough relative to the margin, the second is larger than the first, and the business consumes cash in the very year it reports its best profit.
Three consequences follow, and all three are examinable.
Fast growth is a cash problem, not a trading problem. The cure is funding or faster collection, never "sell more".
The cash drain reverses when growth slows. A business whose sales stop growing suddenly produces cash, because receivables stop rising. Profitable companies therefore look healthiest in cash terms when they have stopped expanding, which is the opposite of how most people read it.
Thin margins make it worse. The thinner the margin, the less profit there is to fund each rupee of extra receivable.
The worked example below runs three years of this and reconciles the whole thing to a single figure, twice.
The three statements, and the question each one answers
Once you accept that profit and cash are different, three statements stop being a formality and become the minimum.
The statement of profit or loss
Asks: did we trade profitably over the period? It covers a span of time and matches revenue earned against the costs of earning it, regardless of when money moved.
The statement of financial position
Asks: what do we own and owe at one instant? It is a photograph, not a film, and it is where the receivables, inventory, payables and borrowings that caused the gap are actually visible.
The statement of cash flows
Asks: where did the money come from and go? It exists to explain the difference between the first two, which is why its operating section usually starts at profit and adjusts — add back depreciation, then subtract the increase in working capital.
They articulate. The profit for the year, less anything paid to owners, changes the equity in the position statement; the cash line in the position statement is where the cash flow statement ends. If the three do not tie, something is wrong — and a question that gives you two of them is usually asking you to find the third.
Why an actuary is made to learn this
An insurer collects premiums before it pays claims, which is the pleasant version of the same timing gap and the reason insurers hold large investment portfolios. The unpleasant version is the same arithmetic in reverse: a long-tailed liability recognised today and settled in a decade. Reading a set of accounts and asking "when does the cash actually move?" is the habit this page is for, and it is the same habit that stops an actuary from treating a reported profit as money available to distribute.
Where marks are lost
Calling the gap a sign of manipulation. A growing, profitable, cash-hungry company is the normal case, not a red flag. The flag is a gap that keeps widening while sales are flat.
Adding depreciation back twice, or subtracting a working-capital increase as though it were an expense. Write the reconciliation as a short, labelled list and most sign errors disappear.
Treating a cash surplus as good news without asking where it came from. Cash generated by collapsing sales, or by not paying suppliers, or by selling a factory, is not the same as cash generated by trading.
Confusing profit with distributable profit. What a company may lawfully pay out is a separate test, and having the cash is not the same as being allowed to use it.
Questions students ask
Which statement would I look at first?
The cash flow statement, and specifically the operating section. It is the hardest of the three to flatter, because the cash either arrived or it did not. Then read the position statement to see what the business is carrying, and the profit statement last.
If cash is harder to flatter, why not report only cash?
Because a pure cash account would show a company as brilliant in the year it stopped investing and collected its debts, and terrible in the year it built a factory. It answers "did money move?" and cannot answer "did we trade well?" — and a business is bought, sold and valued on the second question.
Can the gap go the other way?
Routinely. A business paid in advance — a subscription, an annual fee, an insurance premium — collects before it earns, so cash runs ahead of profit, and its growth generates cash instead of consuming it. Same arithmetic, opposite sign, and a far more comfortable business to finance.
A worked example
An invented example, built for this page. A recruitment agency in Hyderabad, growing fast. Every figure is made up and chosen so the arithmetic is exact.
The rules of the business, held constant for three years:
- Clients are invoiced on placement and pay 90 days later. On a 360-day year that means receivables always stand at one quarter of the year's fee income.
- Consultants' salaries run at 90% of fee income and are paid in the month they are incurred, so there are no payables.
- There is no inventory and no equipment, so there is nothing to depreciate. Removing those on purpose leaves one gap on show instead of four.
- It starts with nothing owed to it.
Three years of trading
| Year 1 | Year 2 | Year 3 | |
|---|---|---|---|
| Fee income | ₹400 lakh | ₹800 lakh | ₹1,200 lakh |
| Growth on the year before | — | +100% | +50% |
| Salaries, 90% of income | ₹360 lakh | ₹720 lakh | ₹1,080 lakh |
| Profit | ₹40 lakh | ₹80 lakh | ₹120 lakh |
Three profitable years, each better than the last. No loss anywhere.
What the clients owe at each year end
Receivables are a quarter of the year's income, so from the printed income figures:
| Year 1 | Year 2 | Year 3 | |
|---|---|---|---|
| Receivables at year end | 400 ÷ 4 = ₹100 lakh | 800 ÷ 4 = ₹200 lakh | 1,200 ÷ 4 = ₹300 lakh |
| Increase during the year | ₹100 lakh | ₹100 lakh | ₹100 lakh |
Now the cash
Cash from operations is profit less the increase in receivables, using the figures printed above:
| Year 1 | Year 2 | Year 3 | |
|---|---|---|---|
| Profit | ₹40 lakh | ₹80 lakh | ₹120 lakh |
| Less increase in receivables | (₹100 lakh) | (₹100 lakh) | (₹100 lakh) |
| Cash from operations | (₹60 lakh) | (₹20 lakh) | ₹20 lakh |
| Cumulative cash | (₹60 lakh) | (₹80 lakh) | (₹60 lakh) |
Read the two tables together. The agency reported ₹240 lakh of profit across three years — 40 + 80 + 120 — and consumed ₹60 lakh of cash doing it. It needed an overdraft or an injection in every one of those years, and it never made a loss.
Check the whole thing a second way
Forget the year-by-year table. Over any period, cash from operations must equal total profit less whatever is still owed at the end, because the only gap in this business is receivables:
which is the figure in the last row. Two independent routes, the same ₹60 lakh. That identity is also the reconciliation the cash flow statement performs, written on one line.
The turn, and why it comes
Year 3 is the first cash-positive year, and nothing about the trading improved: the margin is 10% in all three years. What changed is the rate of growth. Income rose by ₹400 lakh in both Year 2 and Year 3, but profit rises with the level of sales while the receivable increase depends on the increase in sales, and profit overtook it between the two.
The crossover can be located exactly. Cash from operations is positive when 0.10 × sales exceeds 0.25 × increase in sales, that is when the increase is less than 0.40 × sales. In Year 3, sales are ₹1,200 lakh and the increase is ₹400 lakh, which is one third of sales and so below the 40% threshold — and 120 − 100 = ₹20 lakh confirms it.
Test the rule against Year 2 as well. Sales ₹800 lakh, increase ₹400 lakh, which is 50% of sales and above the threshold, so cash should be negative — and it is, at −₹20 lakh. The rule and the table agree in both years.
One honest caveat about that threshold. It holds for this business because its only working-capital item is receivables at a quarter of sales and its margin is exactly 10%. Change either and the 40% changes with it. The method transfers; the number does not.
