What Is Cash Flow? - Definition, Examples, Types & Analysis

What Is Cash Flow?

Cash flow represents the movement of money in and out of a business over a specific period. It's the net amount of cash and cash equivalents being transferred into and out of a company. Understanding business cash flow is fundamental to running a successful enterprise, as it directly impacts your ability to pay bills, invest in growth, and maintain operations.

Why Is Cash Flow Important?

Cash is the lifeblood of any business, plain and simple. When a business has more cash inflow than cash outflow, it can meet its payroll obligations on time, purchase inventory, and make future investments. But if there is not enough cash, the business can have serious problems such as making late payments or declaring bankruptcy.

It is even possible for a profitable company to go out of business if it runs out of cash. This is because cash flows and profitability, or sales, are not the same thing: cash is what actually moves in and out of the company's bank account.

Formula and Calculation of Cash Flow

The basic formula for cash flow looks like this:

Cash Flow=Total Cash Inflows−Total Cash Outflows

• Total cash inflows: All the cash received by the company (from sales, loans, etc.)

• Total cash outflows: All cash paid by the company (to suppliers, wages, rent, interest, etc.)

Expanded Calculation

Typically, businesses measure cash flow for a single period using information from three activities: 

• Operating (business core activity)

• Investing (buy and sell assets)

• Financing (spend and repay money)

Let’s make this simple and break down an example.

Example:

A small shop receives ₹100,000 in sales, spends ₹40,000 on inventory, pays ₹20,000 in salaries, ₹5,000 rent, and makes ₹10,000 loan repayment.
Total Outflows = ₹40,000 + ₹20,000 + ₹5,000 + ₹10,000 = ₹75,000
Cash Flow = ₹100,000 - ₹75,000 = ₹25,000

This ₹25,000 indicates the business is bringing in more money than it’s spending.

Understanding Cash Flow

The cash flow depicts the real financial health of the business not just what the company is earning "on paper." It assesses the actual movement of cash in terms of payments and receipts and answers the key question: "Can the business pay its expenses, pay its employees, or pay for a new investment?"

• Positive cash flow (more incoming): The business can afford its expenses and pay for a new business opportunity as well.

• Negative cash flow (more outgoing): The business would have to find cash, borrow money, and/or cut costs to avoid serious consequences.

Sometimes businesses that show "profit" on an income statement can run into cash flow trouble as they allow their customers to pay on credit or they expend too much to get sales, which ties up working capital until customer receipts come in. 

What Is a Cash Flow Statement?

A cash flow statement is a form of financial report that records all cash being received from, and paid out to, external parties, for a defined period. It is one of the three major financial statements of any company, and is created alongside:

• Balance Sheet (what the company owns and owes).

• Income Statement (profits or losses).

The cash flow statement is divided into 3 types of cash flows:

1. Cash Flow from Operating Activities (CFO):

Cash received and paid for the ongoing operations of the company (selling goods or services, paying for supplies, paying employee wages).

2. Cash Flow from Investing Activities (CFI):

Cash spending used to purchase (or, cash or receipt of selling) big assets (equipment, property, investments, etc).

3. Cash Flow from Financing Activities (CFF):

Cash received from investors or banks or other loans, or cash repaid to shareholders and repaid to lenders.

The cash flow statement is a tool anyone (owner, manager, investor, etc.) can use to see where cash is coming from, where it is going, and if the business is liquid, or in trouble.

Types of Cash Flow

There are four main types of cash flow you should know as you learn how businesses manage and analyze their money:

1. Free Cash Flow (FCF)

Free Cash Flow is the money left after operating expenses and buying assets (“capital expenditures”).

Free Cash Flow (FCF)=Operating Cash Flow−Capital Expenditures

• It tells how much cash a company can use for growth, debt repayment, or paying shareholders.

Examples: If a company’s Operating Cash Flow is ₹30,000 and it spends ₹10,000 to buy machinery, Free Cash Flow is ₹20,000.

2. Cash Flow From Operations (CFO)

This is cash generated from regular operations, like making and selling products. It is only real cash, to be spent or received today — no "paper" profit.

Examples: Customer payments, supplier payments, wages, tax payments.

3. Cash Flow From Investing (CFI)

Cash from buying or selling long-term assets.

Examples: Buying machines, land, investments. Selling equipment or property.

4. Cash Flow From Financing (CFF)

Cash from borrowing or paying back money, or from the owners/shareholders.

Examples: Getting loans, issuing shares, paying dividends, repaying debt.

How to Analyze Cash Flows

Step 1: Review Each Section of the Statement

Begin with the Operating, Investing, and Financing Sections. Is cash mainly "coming in," or "going out"? Is the company consistently generating cash from its operations?

Step 2: Focus On Operations

Strong companies typically have stable and positive operating cash flow. When a company becomes dependent on financing (borrowing) or is constantly dependent on selling (assets), that company should be considered questionable.

Step 3: Compare Over Time

Study cash flow over various periods, whether quarters or years. Each year and quarter will have changes and fluctuations.

Step 4: Watch for Red Flags

Red flags include significant declines in operating cash flow or that a company is most frequently asset sales or continual reliance on additional financing for future operations.

Step 5: Use Ratios and Metrics

There are several popular ways of measuring cash flow prospects:

• Operating Cash Flow Ratio: can measure whether an ensuing cash flow can sustain the existing liabilities.

• Free Cash Flow Yield: demonstrates how much FCF the company generates versus the value of the company.

Example of Cash Flow

Let’s see a very simple example a year’s cash flow statement for a small shop.

Explanation:
The shop made ₹50,000 from operations, spent ₹15,000 for investing, and got ₹23,000 from financing, ending up with ₹58,000 extra cash for the year.

How Are Cash Flows Different From Revenues?

• Revenue is the total sales/remittances generated (even if the customer has not paid the company yet).

• Cash flow is only when cash comes into or leaves the business.

Example:

A business sells a product for ₹10,000 (revenue) but the customer will pay in two months. For the moment, this sale increases revenue, but does NOT increase cash flow, because no cash has come in yet.

What Is the Difference Between Cash Flow and Profit?

Profit is what's left after subtracting all expenses from revenue on paper. Cash Flow is the actual movement of cash.

Key Differences:

Example: A company might show $10,000 profit but have negative cash flow if customers haven't paid their invoices yet.

Understanding Cash Inflow Cash Outflow in Business Cash Flow

Cash inflow cash outflow is the fundamental concept that drives business cash flow management. Cash inflow represents all money coming into your business, while cash outflow means all money going out of your business. The cash outflow meaning refers to any expense or payment that reduces your cash balance. The importance of cash flow statement lies in tracking these movements to ensure business sustainability.

What Is Free Cash Flow, and Why Is It Important?

Free Cash Flow (FCF) refers to the cash remaining after paying for everything required to keep a business functioning.

Free Cash Flow can be used for:

• Repaying debt

• Purchasing new assets

• Distributions of cash to owners or dividends

• Saving for future purposes

Free cash flow has significance to an investor, as a company that generates free cash flow can invest in new projects and endure difficult times.

Why Is the Price-to-Cash Flow Ratio Used?

The Price-to-Cash Flow Ratio is a number that compares a company’s stock price to its cash flow per share. Investors look for lower ratios, meaning the stock is “cheaper” compared to how much cash the business actually makes.

Price-to-Cash Flow Ratio=Market Price per Share/Cash Flow per Share

• A lower ratio could be a sign of a good deal.

• A very high ratio could mean the stock is expensive compared to cash generated.

Do Companies Need to Issue a Cash Flow Statement?

Most public companies have to provide investors with a cash flow statement (both quarterly and annually). This is a requirement set by international accounting standards (like GAAP and IFRS). It helps to keep investors informed, and protects everybody from nasty surprises. 

Even smaller businesses or startups should consider keeping cash flow statements for their own planning purposes even if it is not a legal requirement. This practice helps keep control over your finances.

How Cash Flow Links to Other Financial Statements

• The income statement shows whether the company made profits or losses (it may have credit sales that have no cash movement). 

• The Balance Sheet shows what the company owned and owed at one point in time (the assets and the liabilities). 

• The cash flow statement explains the real (cash) changes that link the two. All three need to be examined together to get an accurate financial picture.

Cash Flow Analysis for Investors and Managers

Investors, lenders, and business owners use cash flow analysis to:

• Determine if the firm earns cash flow from its core business (rather than selling assets or borrowing)

• Evaluate the company's ability to meet its obligations or survive troubled times

• Determine when to invest additional funds or act conservatively

Managers can use cash flow reports to:

• Forecast upcoming costs or expenses

• Make decisions about inventories, payroll, or expansion

• Determine whether the firm exhibits signs of trouble, such as amassing debt or running out of money.

When analyzing cash flow, important points include:

• Sustained positive cash from operations

• Household cash inflows that regularly equal or exceed cash outflows

• Constant ability to satisfy obligations and reinvest Funds without taking on too much debt.
