Cash flow from operations (CFO) is the cash your business generated from its normal trading during a period. The most common formula is the indirect method: CFO = net income + non-cash expenses − gains on asset sales + losses on asset sales − increases in operating assets + decreases in operating assets + increases in operating liabilities − decreases in operating liabilities. In plain terms, you start with profit and undo everything that moved profit without moving cash.
This guide walks through that formula line by line with a worked example, shows the direct method for comparison, and explains the operating cash flow ratio, which tells you whether operating cash can cover the bills due in the next twelve months.
Why profit and operating cash flow are different numbers
Accrual accounting records revenue when you earn it and expenses when you incur them, not when money changes hands. That is the right way to measure performance, but it means a profitable month can leave your bank balance lower than it started. Three things cause most of the gap:
- Non-cash expenses such as depreciation and amortisation reduce profit, but no cash leaves the business when you book them.
- Working capital movements: if customers owe you more at the end of the year than at the start, some of your revenue is still sitting in receivables rather than the bank. Stock you have bought but not sold works the same way.
- Gains and losses on selling assets sit in profit, but the cash from the sale belongs in investing activities, not operations.
Cash flow from operations strips these out so you can see the cash that the core business actually produced.
The cash flow from operations formula, term by term
1. Start with net income
Take net income (profit after tax) from the income statement for the same period. Companies reporting under IFRS should note that for annual periods beginning on or after 1 January 2027, amendments made by IFRS 18 require the indirect method to start from the new operating profit or loss subtotal instead. US GAAP reporters keep starting from net income.
2. Add back non-cash expenses
Depreciation, amortisation, impairment charges and similar items reduced profit without using cash, so add them back. Share-based pay and unrealised foreign exchange losses are other common examples.
3. Remove gains, add back losses on asset disposals
If you sold a machine for more than its book value, the gain inflated profit. Subtract it here, because the full sale proceeds will appear under investing activities. A loss on disposal is added back for the same reason.
4. Adjust for changes in operating working capital
Compare the opening and closing balance sheets for each operating current asset and liability:
- Increase in receivables, inventory or prepayments: subtract (cash is tied up).
- Decrease in receivables, inventory or prepayments: add (cash was released).
- Increase in payables, accrued expenses or tax payable: add (you held on to cash).
- Decrease in payables, accrued expenses or tax payable: subtract (you paid down obligations).
Leave out short-term borrowings, the current portion of long-term loans and dividends payable. Those are financing items even though they sit in current liabilities.
Worked example: Harbourline Coffee Roasters
Harbourline is a wholesale coffee roaster that supplies cafés and offices. For the year just ended it reported net income of $84,000. Here is how its bookkeeper builds cash flow from operations from the income statement and the two year-end balance sheets.
- Net income: $84,000.
- Add depreciation on roasters, grinders and the delivery van: +$26,000.
- Add amortisation of its ordering software: +$4,000.
- Subtract the gain on selling an old sample roaster (sold for $15,000, book value $9,000): −$6,000. The $15,000 of proceeds goes to investing activities.
- Accounts receivable rose from $112,000 to $150,000 after Harbourline signed two office-catering chains on 45-day terms: −$38,000.
- Inventory of green beans fell by $9,000 because the roaster ran its stock down before a price rise: +$9,000.
- Prepaid expenses rose by $3,000 (annual insurance paid in advance): −$3,000.
- Accounts payable to bean importers rose by $14,000: +$14,000.
- Accrued wages fell by $5,000: −$5,000.
- Income tax payable rose by $2,000: +$2,000.
Cash flow from operations = 84,000 + 26,000 + 4,000 − 6,000 − 38,000 + 9,000 − 3,000 + 14,000 − 5,000 + 2,000 = $87,000.
Operating cash came in slightly above net income, but notice what nearly swallowed it: $38,000 of new receivables. Harbourline's growth was real, but much of it had not been paid for yet.
The direct method: same answer, different view
The direct method lists actual cash receipts and payments instead of reconciling from profit:
CFO = cash received from customers − cash paid to suppliers − cash paid to employees − other operating cash payments − income taxes paid (plus or minus interest, depending on how your framework classifies it).
Both IFRS and US GAAP allow either method, and when the books are right both give the same total. The direct method is easier for a non-accountant to read; the indirect method is better at explaining why cash and profit differ. Many owners find it useful to look at both.
The operating cash flow ratio
The operating cash flow ratio measures whether the cash your operations generate could cover your short-term obligations:
Operating cash flow ratio = cash flow from operations ÷ current liabilities
Take current liabilities from the closing balance sheet. Some analysts use the average of opening and closing current liabilities instead; whichever you choose, use it consistently from year to year.
Harbourline's ratio
At year end Harbourline owed $61,000 to suppliers, $9,000 in accrued wages, $7,000 in income tax and $18,000 as the current portion of its equipment loan, so current liabilities total $95,000.
Operating cash flow ratio = 87,000 ÷ 95,000 = 0.92
A ratio below 1.0 means one year of operating cash would not quite cover everything due within the next year, so the business is relying partly on its opening cash balance, collections from the slow-paying customers, or borrowing. Had receivables stayed flat, CFO would have been $125,000 and the ratio about 1.32. That single comparison tells Harbourline's owner where to focus: tightening the 45-day terms, not cutting costs.
How to read the ratio
- Above 1.0: operations generate more cash than the short-term bills require. A higher figure means lower short-term risk.
- Around 1.0: little margin for a slow month or a lost customer.
- Below 1.0: worth investigating, but not automatically a crisis. Check whether the cause is temporary (a growth spurt in receivables, a one-off tax payment) or structural (thin margins, chronic late payment).
Compare the ratio with your own past years and with similar businesses rather than with a universal benchmark. A subscription software company and a wholesale distributor will have very different normal ranges.
A second useful check: cash conversion
Divide CFO by net income. Harbourline's figure is 87,000 ÷ 84,000, or about 1.04. A business whose operating cash runs persistently below its profit, year after year, is usually piling up receivables or inventory, or recognising revenue earlier than customers pay. One year proves little; a three-year trend tells you a lot.
Common mistakes when calculating cash flow from operations
- Getting the working capital signs backwards. An increase in an asset uses cash; an increase in a liability provides it. If your CFO looks too good to be true, check the signs first.
- Leaving the disposal gain in. If you add the sale proceeds to investing but keep the gain in operations, you count part of the same cash twice.
- Treating loan movements as working capital. Changes in short-term borrowings and the current portion of term loans belong in financing.
- Using the cash balance on the balance sheet as CFO. The change in your bank balance is the total of operating, investing and financing flows, not operating alone.
- Mixing periods. Net income for twelve months must be matched with balance sheets twelve months apart.
- Ignoring classification choices. Interest, dividends and income taxes are classified differently under US GAAP and IFRS, so CFO for two similar companies may not be directly comparable. Read the accounting policy note before comparing.
hellobooks< / a > -helps">How HelloBooks helps
HelloBooks produces a cash flow statement using either the direct or the indirect method straight from your ledger, so you do not have to rebuild the working capital adjustments by hand each period. Bank feeds and bank reconciliation keep the cash side accurate, period-end closing handles depreciation, accruals and prepayments, and the AR aging report shows which customers are behind the receivables build-up. Automated overdue-invoice reminders and payment links help you collect faster, which is usually the quickest way to lift operating cash flow. You or your accountant still review the statement before relying on it.
