It takes many things to start and run a successful small business: passion, determination, discipline, and the right people, but the best-laid plans will go nowhere without one key ingredient—cash. The way you manage your cash flow can make or break your business and affect your ability to grow. So knowing how to calculate cash flow at any given time is an important skill for all small business owners.
Small businesses need an easy formula to help them analyze how they use cash and project how much cash they’re going to need to grow their business and meet their future obligations. Knowing how to calculate cash flow is and will be a real lifesaver for your business down the road.
How you do this is easier than it might seem. The first step is to know the most important cash flow reports: the statement of cash flows and the cash flow forecast. Here are easy cash flow formulas you can follow to calculate each.
Here’s a quick example of the cash flow formula used on the cash flow statement:
Cash from operating activities +(-)
Cash from investing activities +(-)
Cash from financing activities +
Beginning cash balance =
Ending cash balance
Let’s explore what each of these mean.
Accountants often hear this question over and over again from many small business owners:
“If I have a profit for the year, why don’t I have any money in my bank account?”
It’s certainly tough to see this as a business owner. But, the answer really comes down to the fact that cash flow isn’t profit. Cash flow is simply the movement of money in and out of a business. But many business owners find themselves asking this question because, although they’re familiar with their profit and loss and balance sheet statements, fewer know how to calculate cash flow and, therefore, do not review their cash flow statement regularly.
That hopefully will change for you starting today. As cash flow is what drives your business, you should know where it stands at all times.
To do this, the first thing you need to know is that the cash flow formula used in a cash flow statement uses information from both the P&L and balance sheet to show the sources of cash inflows and outflows during a specific period.
This information is exactly what you need to solve the “where is my money going” dilemma.
Here’s how it works:
Transactions are categorized into three buckets of activities:
Once your transactions have been categorized, you’ll see and understand why the formula (referenced above) for the cash flow statement looks like this:
The statement of cash flows provides really great insight into how a business is managing its money. It helps you get an even clearer idea of what types of activities are contributing to the cash inflows and outflows. In case you haven’t figured it out yet, this is why you should know how to prepare a cash flow statement and be referencing it often.
If you’re still not convinced, here’s an example of how how this cash flow formula could help your business:
Company A has $125,000 of profit for the year but only $5,000 in the bank at the end of the year.
But how can this be? Let’s take a look at a rough outline of how to calculate cash flow by looking at their cash flow statement to see what’s going on.
This example illustrates why it’s so important to review the profit and loss, balance sheet, and the statement of cash flows in order to get the full picture of a company’s finances. While Company A was profitable, they still had $75,000 uncollected from their customers and owed vendors $25,000 at the end of the year. These non-cash transactions results in a cash basis income of only $75,000 for the period. They also used $45,000 to purchase new equipment, and the owner took out $35,000 as a draw from the company, which left only $5,000 in the bank at the end of the year.
As you can see, profit doesn’t give the full picture of what is happening in a business. But, knowing how to prepare a cash flow statement and doing it often certainly will. It never hurts to be over-prepared and over-aware when it comes to your business’s finances.
Another cash flow formula that you need to use often is a cash flow forecast. This will help your business predict what your cash balance will be in the future.
This report can help you determine whether your business will be able to meet its financial obligations by taking into account the current cash balance and adding or subtracting expected future cash inflows and outflows. It’s a great cash flow financial calculator in that it’s forward-leaning and can help your make decisions for the future, like indicating whether it’s a good time to consider making an investment or to seek funding from business loans, cash flow loans, sales of property, or investors.
Here’s how to calculate cash flow for the future:
Start with your current cash balance and add the amount of cash you expect to receive during the forecast period. This could be cash from customers, loan proceeds, or cash from investors.
Then, deduct your expected cash outflows for the period including things such as unpaid bills to vendors, loan payments, payroll, and other fixed expenses that must be paid during the period. A cash flow forecast is typically reported by a specific period such as week, month, or quarter.
The cash flow formula will look like this:
Beginning cash + projected inflows – projected outflows = Ending cash
It seems pretty simple, but let’s look at an example to make sure it is clear.
Company A wants to buy a new machine for $25,000 in order to increase production to meet increasing customer demands, and they need to decide whether to finance the purchase or pay with cash. Either way, the bank requires that they maintain a balance of $15,000 in their account at all times. The owner knows how to calculate cash flow and has done an analysis of the expected cash inflows and outflows for the next six weeks:
This forecast indicates a few things:
By knowing how to calculate cash flow and preparing the cash flow forecast, Company A determines that in order to purchase the machine during the next six weeks, they need to seek outside financing for at least part of the purchase so they can maintain their minimum required balance and be able to meet their other financial obligations.
As you can see, a cash flow formula like the one used in a cash flow forecast can be essential in helping you make day-to-day decisions for your business. It can help you plan when to spend money, and be much more deliberate with where and when your money goes.
There are lots of resources available to help businesses manage their cash flow, as it is such an essential part of running a business.
