If you have been stressed out and struggling to streamline your finances so that you no longer have to juggle paying bills every week by delaying payments to suppliers, I have a solution for you.

Here’s the thing.

You may be an entrepreneur or a small business owner. If endless cash flow worries are too common for you, I want to introduce you to a cash flow calculator.

But before we proceed, why would you want to listen to me?

I’m a chartered certified accountant, and I help businesses calculate cash flow to improve their finances. I have over 20 years of experience across different sectors. Using my proprietary cash flow maximisation software, I serve my client through my consulting company, Hungry Cash Flow Limited. 

Let’s dive in.

What is a cash flow calculator?

A cash flow calculator is a tool to provide a clear snapshot of the company’s cash movements. It considers all cash inflows and outflows in a set time. This lets you see a bird’s eye view of your business’s finances. You can either create a simple spreadsheet template if your business requirements are small or you can use cash flow software to help you save time, hassle and accuracy of data.

From what I have seen with my clients, it is easy for business owners to enter cash flow figures into a tool like this one. They can then use it to understand their cash position without complex calculations.

A Real-life Case Study Dr. James Harlow’s Dental Practice 

The Backstory

Dr James Harlow is an ambitious, growth-minded Bristol-based dental practice owner with an annual patient income of £750,000.

The Cash Flow Challenge

Dr. Harlow’s clinic faced mounting cash flow challenges. They had to pay recurring loan and lease payments. They also had to pay for practice purchases and machines. Also, the government imposed a minimum increment in hourly rates in April 2023. Also, rising inflation rates increased the cost of dental products like gloves and clothes. These factors put even more strain on cash flow. 

Then he had to do dental chair repairs, which cost £7,729.19. So, he had to dip into overdraft just to keep the show running.


Dr Harlow used the cash flow calculator I shared. He used it to record cash in and outflows from private treatments, NHS income, Dental Products sales, and paying staff. He recorded monthly loan and lease repayments and rent.

When the cash flow was calculated, he discovered that he was paying more to dental associates than market rates.

He also discovered that he was paying more for gloves and disposables than he used to pay before. 


He negotiated the rate payment with the dental associate. It improved his cash flow net margin by 5%.

He also renegotiated the deal with the supplier to buy gloves and disposables in bulk. This improved his cash margin by 1.7%

The Result: 

As a result of using the cash flow calculator, he improved his bottom line profit aka cash left for him by 6.7%.

On a business of £750k, He added £50,250 extra cash to his bank account without doing further treatment work.

You can do the same by following this guide to unlock the cash improvement potential.

By the end of this guide, you will have complete know-how to implement the cash flow calculator tool I will share with you.


Why calculate cash flows?

Did you know?

According to Intuit 38% of small business owners have been unable to pay salaries, loans, or themselves. So, it is important to calculate cash flow no matter what stage, size, sector or specific situation you are in.

From my experience as an accountant, I worked with business owners across various sectors and sizes. You need to calculate cash flow for these reasons.

1. Be The Leader in Your Niche

You may have heard an early bird catches the worm. If you are innovative and can offer something extra or different to your competitors, you have a competitive advantage to capture the market. To do this, you need cash to invest.

Whether you have enough or not to find out, you need to calculate cash flow.

2. Make Informed Financial Decisions Based On Financial Facts

Decision-making without knowing the cash flow data impact is like driving a vehicle to reach the destination without checking fuel. You need to calculate cash to make informed decisions.

3. Secure Loans

Loan providers will scrutinize your cash flow to gauge your business’s health and viability. You demonstrate you are a responsible business owner by showing you are doing regular cash flow calculations.

From my experience, those with a clear pattern of showing cash flow reports will likely secure financing.

4. Increased Peace of Mind:

There is no better feeling than peace of mind. Imagine you don’t have to wake up at 2 am in the morning knowing exactly where you are cash flow-wise.

5. Compare with your budget

When you calculate cash flow often, you can compare it to your cash budget. Then, you can see if you are within budget. From my experience , it is simple for my clients to see if they are on track to meet allocated budget for different areas of the business.

Keeping track of each expense including the tax liability is crucial to maintain a healthy budget and ensure financial stability. 

6. Form the basis for cash flow forecasting

Once you have calculated cash flow, it forms the basis for making a cash flow forecast. The forecast uses historical data and future assumptions based on it.

What Are The Components of a Cash Flow Calculator?

 You need to be aware of the components of a cash flow calculator.

CFO (Cash Flow from Operating Activities)

CFO (Cash Flow from Operating Activities) is the cash flow generated from your operations. This means that cash is produced by collecting money from sales, which is kept in the business after paying for costs and expenses. It is the primary source of cash flow in the industry.

Under CFO, you will have two types.

    1. Cash inflow

    1. Cash Outflow

Cash inflow examples are:

    • Cash received from customers


Cash outflow examples are:

CFI (Cash Flow From Investing Activities)

CFI (Cash Flow From Investing Activities) refers to the cash flow generated from investing activities.

Under CFI, you sell the investments to generate cash, and the business invests cash. So the total change in cash flow is called Cash flow from investing activities. 

CFI cash inflow examples are:

    • Sale of property

    • Sales of investment in a business

CFI cash outflow examples are:

    • Inventory- Total cash paid for the period to purchase inventory.

    • Capital expenditures Cash used to purchase capital equipment or land for use in your business.

CFF (Cash Flow from Financing Activities)

CFF is cash flow from financing. It comes from financing activities. This shows how the business is funded using external sources.That could be from banks and angel investors, and if you put money in the business, that’s external funding, too, because you are not your business. 

CFF inflow examples are :

    • Capital contributions- Any cash received from the owner(s) for the period.

    • Stock issuing -Net cash received from issuing stock. Make sure this is the net amount after any fees have been taken into account.

    • New borrowing- Net new borrowing for the period. Include new borrowing as well as the net increase in any line of credit borrowing.
