Cash Flow

Cash flow is an important component of every company. Cash flow refers to the net inflow of liquid funds within a certain period of time. It is calculated as the difference between all incoming and outgoing payments of a company in the period under review. Cash flow is therefore an indicator of the change in liquid funds (cash balance) over a given period and reflects whether more liquid funds were received than paid out during the period (positive cash flow) or vice versa (negative cash flow).

Cash flow in two sentences

Cash flow is the difference between all cash inflows and outflows of a company in a given period – it shows how much liquidity the operating business, investments, and financing activities actually generate or consume. Unlike profit, cash flow is payment-based and therefore harder to manipulate: it reveals whether a company is genuinely generating money.


Inflows − Outflowsbasic formula: cash flow measures real money movements, not accounting profits
3 typesoperating CF (core business), investing CF (fixed assets), financing CF (capital structure)
Free Cash Flowoperating CF minus investing CF – shows the amount freely available for dividends, debt repayment, or growth
Positive vs. negativepositive CF = liquidity increase; negative CF = liquidity decrease – not necessarily bad (e.g. during growth investment phases)

Cash Flow Simply Explained

Cash flow is an important pillar for companies and individuals. It is the net amount of money that flows into or out of a company or person. Cash flow is an important component of the financing process because it helps companies and individuals meet their financial obligations and make risk-free investments in the future. Cash flow is either determined directly by comparing all cash inflows for the period with cash outflows. It is also important to monitor cash flow over a period of time to better predict future financial decisions. [1]

Cash Flow Definition

Cash flow is a term from the world of finance that describes the net flow of cash available to a company or individual. It is an indicator that represents the difference between income and expenses and is therefore an important component in the financing of a company. Cash flow can also be seen as an account balance that is affected by money income and outflow. Companies and investors can use cash flow as an important tool to determine how much money is available to cover costs or make new investments. [2]

Cash Flow Calculation

Cash Flow calculations are an important component in the analysis of financial flows. They help companies determine the earning power of their revenues and ensure that they have enough money to meet their obligations. A proper cash flow calculation is performed by analyzing a company's revenues and expenses over a period of time. The difference between revenues and expenses is then determined, and the result is called cash flow or net cash flow. This value indicates whether a company has sufficient financial resources to meet its obligations

Type of calculation Formula Explanation
Operating cash flow Net income (after taxes) + depreciation and amortization + write-ups + changes in long-term provisions ± changes in working capital Records all cash-generating income and expenses from core business. Shows the liquidity generated by operating activities after taxes within a period.
Investment cash flow Cash flow from investing activities Shows inflows or outflows from investments in property, plant, and equipment or financial assets. A negative value indicates investments, while a positive value indicates divestments.
Financing cash flow Cash flow from financing activities Provides information on cash inflows and outflows from financing activities such as borrowing, repayments or the issue of equity instruments.
Free cash flow Operating cash flow – investment cash flow Shows the freely available cash inflow after investments. Can be used for dividends, debt repayment, or reinvestment.
Cash flow from operating activities Includes all cash inflows and outflows from core business activities, such as sales of goods and related operating expenses. Measures the net liquidity from operating activities for a period.

Cash Flow Formula

The cash flow formula is one of the most important methods for achieving a company's financial goals. It is a mathematical equation that represents a company's income and expenses in order to calculate liquidity. The cash flow formula allows companies to better control their financial situations and avoid short-term liquidity problems. It also helps businesses achieve their financial goals more efficiently and realistically. The cash flow formula is a cost-effective way to understand and manage a company's finances.

The Three Types of Cash Flow

Each component of the cash flow statement illuminates a different area of corporate finance:

Cash flow from operating activities

Operating Cash Flow (OCF)

OCF = Net income + Depreciation ± Changes in working capital

Operating cash flow shows how much liquidity the core business actually generates – independently of investments and financing. It is the single most important metric for a company's sustainable liquidity strength. A persistently negative OCF signals that the core business is consuming more cash than it generates – a serious warning sign.

Example: A retailer receives €500,000 from sales (inflows) and pays suppliers and staff €380,000 (outflows) → operating CF = +€120,000.

Positive: core business generates liquidity – a good sign

Calculation: direct method (cash receipts − cash payments) or indirect method (net income + non-cash charges ± working capital changes)

Cash flow from investing activities

Investing Cash Flow (ICF)

ICF = Proceeds from disposals − Capital expenditure (CapEx)

Investing cash flow captures all cash movements from buying or selling long-term assets: machinery, buildings, equity stakes, intangible assets. A negative investing CF often means the company is investing in its future – which is fundamentally positive. A persistently positive investing CF points to divestments.

Example: A manufacturer purchases a machine for €200,000 and sells an old asset for €30,000 → investing CF = −€170,000.

Negative: growth investment – normal and expected in growth phases

Note: a strongly negative investing CF combined with a negative operating CF can indicate liquidity pressure.

Cash flow from financing activities

Financing Cash Flow (FCF_fin)

FCF_fin = New debt + Equity raised − Repayments − Dividends

Financing cash flow shows how the company is changing its funding structure: new loans, repayments, capital increases, share buybacks, and dividend payments. A positive financing CF means the company is raising capital. Negative: it is returning capital to investors and creditors.

Example: A company takes out a €300,000 bank loan, repays €80,000 of existing debt, and pays €50,000 in dividends → financing CF = +€170,000.

Positive: raising capital – company is externally funded

Mature, profitable companies often have a negative financing CF (debt reduction, share buybacks, dividends) – a sign of strength.

Cash Flow Calculator: Free Cash Flow Live

Enter the cash flows – the calculator determines operating CF, investing CF, and the resulting free cash flow:

120,000 € Operating CF
−170,000 € Investing CF
−50,000 € Free Cash Flow
Negative FCF: the company is investing more than it generates operationally – typical for growth phases.

Sample values from the worked example. Free Cash Flow = Operating CF − Net Investing CF. A negative FCF is not automatically bad – what matters is whether investments promise future returns.
