Profit vs Cash Flow
No Sign-Up. No Paywall.
The P&L says the business made money. The bank balance says otherwise. Both can be right, and the gap between them is where businesses fail.
Two Honest Answers to Different Questions
Profit answers: over this period, did the value the business created exceed the value it consumed? It is measured on the accrual basis, so a sale is recognised when it is earned, not when the customer pays.
Cash flow answers: over this period, did more money arrive than left? It ignores when something was earned and looks only at when it moved.
Neither is a distortion of the other. They are different measurements, and a healthy business needs both. A business can survive a loss-making year with cash in the bank. It cannot survive a profitable year with an empty one.
Where the Gap Comes From
| Item | Effect on profit | Effect on cash |
|---|---|---|
| Credit sale not yet collected | Increases profit now | No cash until the customer pays |
| Inventory bought and unsold | None until it is sold | Cash out now |
| Depreciation | Reduces profit | No cash movement at all |
| Capital expenditure | Not an expense; capitalised | Full cash out immediately |
| Loan principal repayment | Not an expense | Cash out |
| Loan interest | Reduces profit | Cash out |
| Supplier credit taken | None | Cash retained for now |
| Advance received from a customer | Not revenue yet | Cash in now |
Four of these move cash without touching profit, and two move profit without touching cash. That is the entire mechanism.
Why Growth Consumes Cash
The dangerous case is not a failing business. It is a fast-growing one.
Grow revenue by half and receivables typically grow by half too, and inventory with them. Both must be funded before the customer pays. Profit rises on the P&L while cash leaves the bank, and the faster the growth the wider the gap.
This is why profitable businesses fail. They do not run out of profit; they run out of the working capital needed to support the next order. Increase the receivables and inventory figures in the calculator above and watch the cash column fall while profit stays exactly where it was.
The Cash Conversion Cycle Is the Number to Watch
Days inventory outstanding, plus days sales outstanding, less days payables outstanding, gives the cash conversion cycle: the number of days between paying for something and being paid for it.
Every day in that cycle is a day your money funds someone else’s business. A cycle of ninety days on ₹12 crore of revenue ties up roughly ₹3 crore permanently, which has to come from profits, a loan or the owner.
Shortening the cycle releases cash without a single extra sale. Invoice on dispatch rather than at month end, take deposits on large orders, chase at thirty days rather than sixty, and negotiate supplier terms deliberately rather than accepting whatever is offered. The working capital calculator computes the cycle from your own figures.
Where Each Number Is Right
Judge by profit when
- Assessing whether the business model works at all
- Comparing performance against a competitor or a prior year
- Computing tax, which is levied on profit not on cash
- Valuing the business on an earnings basis
Judge by cash when
- Deciding whether you can make payroll next month
- Planning capex, a loan repayment or a dividend
- Assessing whether growth is affordable
- Testing earnings quality — profit without cash behind it is a warning
Reading Earnings Quality
Compare cash from operations with profit after tax over several years. In a healthy business they track each other reasonably closely.
When profit rises steadily and operating cash flow stagnates or falls, something is wrong: revenue may be recognised aggressively, receivables may be uncollectible, or inventory may be obsolete and still carried at cost. Several of India’s better-known corporate failures were visible in that divergence years before they were visible anywhere else.
It is the single most useful ratio an owner or an investor can watch, and it costs nothing to compute.
How to Decide What to Fix
If profit is healthy and cash is not, the problem is working capital or capex, not the business model. Attack the cash conversion cycle first, because it releases money you have already earned.
If cash is healthy and profit is not, you may be living off depreciation, supplier credit or deferred maintenance, none of which is repeatable. That is a margin problem, and the break-even and margin calculators are the place to start.
If both are weak, the model needs work before anything else does.

Sources and Method
The calculator computes profit after tax from the revenue, cash costs, depreciation and tax rate you enter, then derives free cash flow by adding back depreciation and deducting the working capital movement and the capex and principal repayment. It is a simplified indirect-method reconciliation, not a statutory cash flow statement.
