Business owners want clarity about their company’s financial health, and a financially healthy business means growth. A major player in business growth is free cash flow, but understanding what this is and how to calculate it can be tricky.

Understanding free cash flow helps business owners plan for future growth and if the company is incorporated, plan for investments that would improve shareholder value. Free cash flow can be used in a business plan as part of financial planning and forecasting.

What is free cash flow?

Free cash flow (FCF) is a measurement of a business’s financial health and performance. It is all the financial assets left after deduction of operating costs (wages, supplies, overhead) and purchasing assets (equipment, property, other major investments).

Free cash flow is a measurement of available cash that can be distributed among investors or used for other business growth purposes. A healthy level of free cash flow is the ideal position that every entrepreneur wants to be in.

How to calculate free cash flow

There are a few ways to calculate free cash flow, but for the most part, it’s fairly simple. The most commonly used formula is:

Free cash flow = operating cash flow (OCF) – capital expenditures

While the formula may be simple, understanding a business’s operating cash flow and capital expenditures takes strong accounting skills and one of the major reasons why keeping accurate financial statements and accounting is so important for a business.

Using operating cash flow

Operating cash flow is cash flow from the operations of a business for its regular business activities such as sales and services. It is the first assessment calculated on a business’s cash flow statement.

While cash flow statements (also known as a statement of cash) aren’t used by every business, they are an essential part of accounting for companies that use the accrual accounting method. A cash flow statement provides information on the amount of revenue a business has generated but may not have received yet.

An operating cash flow statement is broken down into three components:

Operating activities:

This is the day-to-day operating earnings of a business. This includes revenue pending from outstanding customers and where those funds will be allocated.

Investment activities:

This is cash flow from investments and how much profit a business is earning from those investments.

Financing activities:

The financing activities are a record of the sources of cash accrued from investors and banks. This is similar to a balance statement’s liabilities, including outstanding debts and loans.

Using sales revenue

Sales revenue is just what it sounds like: revenue garnered from sales of goods and services. The terms “sales” and “revenue” are often used interchangeably, but revenue doesn’t necessarily mean cash on hand. Sales are all the earnings from sales of products and services only, revenue is all the money a business receives from all sources.

Sales revenue can be listed on an income statement as either gross (total revenue before any debt or operating expenses deductions) or net (all debts and operating expenses deducted).

Sales revenue is a valuable metric for financial reporting and forecasting, which is why it is always listed at the top of an income statement. Think of it as the reference point for all other calculations and analyses on the income statement.

Calculating sales revenue is a three-step process:

1. Determine the unit price

Determine the price of each unit, product, or service you will be selling. For example, if you are selling print-on-demand t-shirts at a price point of $20 each, that will be your unit price. Most businesses, however, sell a much wider range of products and services, so this step will need to be completed for each and every product and service that the business sells.

2. Calculate the total units sold

After unit pricing, this is fairly self-explanatory and requires taking inventory of all stock sold and still remaining on-hand. With these figures, you can calculate the amount of sales revenue generated from operating activities.

3. Units multiplied by the price

Now that you have the individual unit price and the amount of each unit sold, you can simply multiply them together to get the total amount of sales revenue generated. Let’s take the print-on-demand t-shirt example.

Let’s assume you have two different types of t-shirts for sale: long-sleeve and short-sleeve. The long-sleeve shirts are $30 and the short-sleeve shirts are $20. You sold 1,000 of the long-sleeve shirts and 750 of the short-sleeve shirts. Now do the math:

Long-sleeve shirts: 1,000 x $30 = $30,000.00

Short-sleeve shirts: 750 x $20 = $15,000.00

Total sales revenue: $45,000.00

Using net operating profits

Net operating profits are a business’s earnings after all expenses are deducted except for debts, taxes, and a few other exceptions. Net operating profits aren’t to be confused with net operating income, which is the profit remaining after all expenses have been deducted from revenue of sales.

Net operating profit is the amount of revenue that remains after deducting all the variable and fixed operating costs. Basically, it shows the profit a business is earning and is an invaluable metric on your financial statements.

Net operating profit can be calculated using the following formula:

Net operating profit = operating revenue – cost of goods sold – depreciation and amortization

While the formula looks simple, determining figures such as depreciation and amortization takes some skill and is one of the reasons why many business owners
