# What is the Net Cash Flow Formula & How To Calculate It?

The net cash flow formula helps reveal if a business is performing well or in danger of going bankrupt.

Repeated periods of positive net cash flow are a good sign that your business is ready to expand, whereas repeated periods of negative net cash flow can be a sign that your business is struggling.

This guide will give you an in-depth understanding of net cash flow and how to calculate it using the net cash flow formula.

## What is Net Cash Flow?

Net cash flow (NCF) is a metric that tells you whether more cash came in or went out of a business within a specific period of time. If more cash came in, the result would be a positive cash flow. Whereas if more money went out, the result would be a negative cash flow.

You’d calculate the NCF by looking at your cash flow statement, particularly the three cash flow categories (Operating Activities, Investing Activities, and Financing Activities.)

## What is the Net Cash Flow Formula?

Put simply, NCF is a business’s total cash inflow minus the total cash outflow over a particular period.

NCF= total cash inflow - total cash outflow

An extended formula is:

NCF=  Net cash flows from operating activities

+ Net cash flows from investing activities  + Net cash flows from financial activities

• Net cash flows from operating activities: Examples of cash flow in net operating activities include the change in net income for the period as well as the adjustments to reconcile net cash provided by or used in operating activities, to name a few.
• Net cash flows from investing activities: Some examples of cash inflows from investing activities include the sale of investment properties or securities. Examples of cash outflows are capital expenditures (i.e., purchase of fixed assets).
• Net cash flows from financial activities: Some examples of inflows of financing activities are proceeds from a loan to finance the business and examples of outflows are repayments of the loan.

### Net Cash Flow Example

Josh from Company ABC is trying to determine the NCF of his business over the last month.

When he looks at the statement of cash flow, he sees the following:

• Cash flow from operations: \$50,000
• Cash flow from investing:  (\$70,000)
• Cash flow from financing: \$15,000

To calculate NCF for the month, he’d do the following calculation:

NCF= \$50,000 + (- \$70,000) + \$15,000

The NCF for the specific period would be a negative cash flow of \$5,000.

Although one period of negative cash flow isn’t necessarily a bad sign, Josh would want to ensure this doesn’t repeatedly happen period over period.

### What is the Operating Cash Flow (OCF) Formula?

Investors and analysts particularly pay attention to the cash flow from operating activities because this reveals a business’s ability to make a profit from core operations. If investing and financing continually produce a significant cash flow, but cash flow from operations are continually in the negative, this can be a red flag.

The most common way to calculate operating cash flow is through the indirect method, which takes into account the net income under an accrual basis of accounting.

OCF = Net Income + Non-Cash Expenses

+/- Changes in Working Capital

Using this method, you start with the net income (taken from the bottom of the income statement) and work backward to determine the operating cash flow. Let’s breakdown the equation:

• Net income: The net income is the starting point of your OCF calculations.
• Changes in working capital: Working capital equals current assets minus current liabilities. Net income factors in current assets (accounts receivable, inventory, etc.) and current liabilities (such as accounts payable), whereas cash flow does not. This is why adjustments to the net income account for changes in working capital.
• Non-cash expenses: Non-cash items, including depreciation, amortization, and stock-based compensation, are expenses created by accounting principles. In other words, they don’t actually involve a cash payment, so although the net income includes these expenses, OCF does not.

## Why Net Cash Flow is Important

NCF gives a business owner and potential investors insight into the financial health of a business. Having negative cash flow for many consecutive months can be a sign that your business is in trouble. On the other hand, consecutive months with positive cash flow can be a sign that your business is thriving.

### Positive Cash Flow

Positive NCF opens up many opportunities for a business, such as the ability to invest in research and development, new equipment, and hire more employees.

### Negative Cash Flow

Negative NCF limits a business’s ability to invest back in the business. Consequently, business owners must figure out ways to improve cash flow through means such as discounts for upfront payments, chasing late payments, or through loans.

NCF also helps business owners make decisions about the future and is particularly important when calculating the payback period of a potential investment.

## Limitations of Net Cash Flow

In isolation, NCF does not tell the full story. The reasons behind a negative NFC can sometimes be positive for the business.

For example, a few consecutive months of negative cash flow can result from paying off large amounts of debt. Conversely, a positive NCF can simply be the result of receiving a \$5,000 loan, which is a lot different from a positive cash flow from making a \$5,000 sale.

Another limitation of NCF is that even if a business makes a capital investment that’ll bring a substantial return on investment in the future, the NCF would still show negative for the specific time period.

This is why it’s important to consider the NCF of periods over periods.

Another way to overcome this limitation is to consider other formulas in tandem with NCF (such as free cash flow).

## Is Net Cash Flow the Same As Net Income?

No, your business can have a high net income, but a negative cash flow. One way this can happen is if many of your customers are on lengthy payment plans or if you allow clients to pay you months after a service is performed.

This is because net income generally considers accounts receivable, but NCF doesn’t. Let's say you made a sale for \$9,000, but the customer only pays you \$3,000 today and \$6,000 over the next two months. Your cash flow from the sale will only be \$3,000 this month, whereas your net income would factor in the entire \$9,000, even though you haven't technically received it yet.

## Key Takeaways

The net cash flow formula gives you key insight into how your business is doing. However, a period of negative cash flow isn’t necessarily a bad thing, just like a period of positive cash flow isn’t necessarily a good thing.

Period over period of negative cash flow should be addressed by following simple cash flow management tips. Manage cash flow to grow your business faster!
