What it means
Profit and cash are not the same thing, which is the first point to grasp. Profit is calculated when a sale is earned and a cost is incurred, whereas net cash flow only counts money that genuinely moved, which is why a profitable business can still run out of money.
The formal calculation adds together three streams from the cash flow statement. Operating cash flow covers day-to-day trading, investing cash flow covers buying and selling long-term assets, and financing cash flow covers borrowing, repayments, share issues and dividends.
Reading the three streams separately tells you far more than the total does. A company with strong operating inflows funding its own equipment purchases is in a very different position from one whose positive net cash flow comes entirely from a new bank loan.
Managers use net cash flow to check that the business can meet payroll, suppliers and loan repayments without further borrowing. Lenders and investors look at the same figure to judge whether a company can service its debt and fund growth from its own resources.
The nuance is that a negative net cash flow is not automatically bad. A growing business that spends heavily on equipment or new premises in a single year will report a negative total while building the capacity that produces cash later, which is why the composition matters as much as the sign.
In practice
Real-world examples.
Example
A recruitment agency reports a $310,000 profit but net cash flow of only $40,000, because clients on 60-day payment terms have pushed receivables up by $270,000. The finance director tightens credit control rather than celebrating the profit figure.
Example
A brewery posts negative net cash flow of $520,000 in the year it installs a new bottling line. The operating stream is strongly positive, and the negative total simply reflects a deliberate one-off investment funded partly from reserves.
Example
A retailer notices its net cash flow turned positive only because it drew down a $400,000 overdraft facility. Operating cash flow was negative for the third quarter running, which is the number the board actually needs to act on.
Think of it
“Net cash flow is the bottom line of your cash statement-did you end up with more or less cash?
Formula
Calculation
Net cash flow = cash inflows - cash outflows
Or, using the cash flow statement: net cash flow = operating cash flow + investing cash flow + financing cash flow
A regional catering company reviews its year. Operating activities generated $420,000, made up of customer receipts less payments to suppliers, staff and tax authorities.
Investing activities used $150,000, being the purchase of two delivery vans and a new commercial kitchen fit-out, shown as a negative because the money left the business. Financing activities used a further $90,000, consisting of $150,000 of loan repayments partly offset by $60,000 of new borrowing.
Net cash flow = $420,000 - $150,000 - $90,000 = $180,000. The company began the year with $250,000 in the bank, so its closing cash balance is $250,000 + $180,000 = $430,000, and the composition is healthy because the trading operation funded both the investment and the debt repayment.Case study
Seen in the real world.
This is a fictional, illustrative scenario. Coppergate Interiors, an invented commercial fit-out contractor, reported profits of about $600,000 in each of two consecutive years and its owners took dividends accordingly. Nobody looked closely at the cash flow statement, which showed net cash flow of $95,000 in year one and -$180,000 in year two.
The reason sat in working capital. The company had won larger projects with longer payment terms, so amounts owed by customers rose by roughly $700,000 across the two years while the business paid its subcontractors within 30 days, meaning it was funding its own growth out of its bank balance.
In this illustrative case the owners suspended dividends for two quarters, negotiated stage payments into new contracts and moved subcontractor terms to 45 days. Net cash flow returned to positive within six months on essentially unchanged trading, which demonstrated that the problem had never been profitability at all.
Watch out
Common mistakes.
- Treating profit and net cash flow as interchangeable, when timing differences in receivables, payables and stock routinely put them far apart.
- Judging the headline figure without checking which of the three streams produced it, so borrowing gets mistaken for trading performance.
- Reading a negative net cash flow as a warning sign when it reflects deliberate, funded investment in productive assets.
Questions
People also ask.
Is net cash flow the same as free cash flow?
No, free cash flow starts from operating cash flow and subtracts capital expenditure, leaving out financing items entirely.
Which period should a small business monitor?
Weekly or monthly, because annual figures hide the seasonal squeezes that actually cause missed payments.
Can a business with positive net cash flow still be in trouble?
Yes, particularly if the inflows came from selling assets or drawing down facilities rather than from trading.
