Cash Flow Analysis: How to Do It (With Formulas and Examples)
Cash flow analysis shows how money actually moves through a business. Here's how to read the three cash flow categories, the key formulas, and how to run the analysis from bank statements.
Cash flow analysis is the process of examining how cash moves in and out of a business — across operating, investing, and financing activities — to understand its real liquidity. Unlike profit, which can include money you haven't collected yet, cash flow tracks actual dollars. It's how you tell whether a business can pay its bills, and how lenders verify a borrower can service debt.

Once transactions are structured, DocuClipper rolls them into income, expense, and cash flow views. Owners and advisors get a clear picture of what happened, not an estimate.
Why cash flow ≠ profit
A business can be profitable on paper and still run out of cash — sales booked but not collected, inventory tying up money, loan principal due. Cash flow analysis closes that gap by following the actual cash, not the accounting income. This is why it's central to both running a business and underwriting one.
The three categories of cash flow
| Category | What it covers | Example |
|---|---|---|
| Operating | Cash from core business operations | Customer payments in, payroll and supplier payments out |
| Investing | Cash from buying/selling long-term assets | Buying equipment, selling property |
| Financing | Cash from debt and equity | Taking a loan, repaying principal, owner draws |
Healthy businesses generally show positive operating cash flow — the core operation funds itself, rather than relying on loans or asset sales to stay afloat.
Key formulas
Net Cash Flow = Cash Inflows − Cash Outflows
Operating Cash Flow = Net Income + Non-Cash Expenses − Increase in Working Capital
Free Cash Flow = Operating Cash Flow − Capital Expenditures
Free cash flow is the cash left after keeping the business running and invested — what's actually available to pay down debt or return to owners.
Put it into practice
Totals hide the story. Timing tells it.
Lumpy inflows and recurring outflows disappear in summary views. Month-by-month cash data from real statements makes runway and seasonality obvious.
How to do a cash flow analysis
- Gather the cash data — typically 3 to 24 months of bank and credit card statements.
- Categorize every transaction into operating, investing, or financing, and separate recurring from one-time.
- Total inflows and outflows per category and per period.
- Calculate the metrics — net cash flow, operating cash flow, and free cash flow.
- Look at the trend. One month tells you little; the pattern across months reveals whether cash flow is stable, seasonal, or deteriorating.
Where the work is
Steps 1–2 are the bottleneck. Pulling months of transactions off PDF statements and categorizing them by hand is slow and error-prone, and it's the difference between a real analysis and a rough guess.
DocuClipper extracts and categorizes transactions from PDF bank statements in minutes, so the inflows and outflows are ready to total — turning the manual data-prep step into something that takes minutes. The same extracted data underpins bank statement analysis for lenders, and it's the input behind metrics like the debt service coverage ratio and income verification.
The bottom line
Cash flow analysis follows the actual dollars — across operating, investing, and financing activities — to show whether a business can fund itself and service its debt. The math is straightforward; the reliability comes from clean, categorized transaction data. Start by turning raw bank statements into structured cash-flow data, then analyze the trend rather than a single month.
