Planning a company's financial health through 3 year cash flow projections is an essential step for any business. Through the use of cash flow projections, businesses can plan to budget, build projections for future investments, and prepare for unexpected financial challenges. However, making a cash flow projection comes with its own set of challenges and avoiding common missteps is integral for a successful plan. Below are some of the pitfalls to avoid when making your 3 year cash flow projections.

Overestimating Market Saturation

Having an accurate 3 year cash flow projection is essential for any business, especially for entrepreneurs and small business owners who are looking to grow and compete. One of the most common errors that many business owners face when preparing projections is overestimating their potential market saturation.

Setting Unrealistic Projections Based on Industry Data

When estimating their business’s market saturation, many business owners rely on industry-wide data. This data can provide an indication of potential market saturation. However, these estimates can be overly optimistic. This is because these figures often do not take into account the local competition and a business’s place within the market.

Not Recognizing the Local Competition

It is essential to recognize the power of local competition when estimating market saturation. This includes other business that may be operating in the same geographical area. If a business is located in a highly competitive area, this may mean that the market saturation is lower compared to the wider industry figures.

Furthermore, it is essential to take into account the size of a local company’s market share when estimating potential market saturation. If a business has a large market share, it may take away from potential sales that other businesses may receive. Therefore, it is important to factor in these considerations when estimating market saturation.

Overall, when making 3 year cash flow projections it is essential to be realistic and honest when estimating potential market saturation. This means using local data and taking into account the local competition in order to ensure that you are making accurate estimations.

Underestimating Business Expenses

It’s easy to make the mistake of underestimating business expenses when making three-year cash flow projections. These can vary greatly depending on your business and the services or products you offer. It is important to have a realistic outlook when it comes to your expenses in order to avoid surprises and financial hardship down the road.

Failing to Consider Employee Costs

Employee costs make up a major portion of most businesses' operating expenses. It is important to take into account salaries and other required employee contributions, including benefits and pension plans. Additionally, you should consider the overhead costs associated with the employment of personnel, such as office space, equipment and supplies.

Not Allocating Funds for Taxes

Taxes can represent a major expense for any business, and it is important to factor these costs into your cash flow projections. Consider any applicable federal, state or local taxes, as well as payroll taxes, sales taxes and any other taxes that may apply to your business. Once you have established the taxes that will affect your business, you can then determine a realistic estimate of the taxes you will need to pay over the course of the three years.

Inaccurate Revenue Forecasting

When making a 3-year cash flow projection, it is important to get revenue estimates right. After all, revenue equals cash flow, so if you underestimate revenue, you can be sure that your projections will be off the mark. Here are some common mistakes when forecasting revenue.

Using overly optimistic sales estimates

One of the most common mistakes in revenue forecasting is to be overly optimistic when estimating future sales. Being overly optimistic can lead to inflated projections and can set you up for disappointment if future sales fail to meet projections. It is important to use conservative estimates that factor in changes in the market, competitive landscape, and any other variables that could impact sales.

Not factoring in economic changes

Another mistake made when forecasting revenue is not factoring in economic changes. When economic changes occur, such as changes in interest rates, new legislation, or changes in the competitive landscape, the impact on revenue can be significant. It is important to stay on top of industry trends and take into account any economic changes that could impact future sales.

  • Stay informed about economic developments that could influence sales
  • Make sure estimates are based on realistic expectations
  • Consider changes in the competitive landscape

Unrealistic Growth Expectations

When it comes to making cash flow projections for the next three years, it is important to understand the potential limitations of your company’s growth. Oftentimes, business owners fail to recognize the potential roadblocks they may face in gaining the success they envision and wind up with unrealistic growth expectations that cannot be met.

Experiencing Rapid Growth Too Soon

In their enthusiasm to get the ball rolling, entrepreneurs may start to expand their businesses too quickly. While it’s important to strive for growth, it’s equally important to plan for it carefully and to understand the potential risks in each decision. By developing a strategic business plan, it is much easier to anticipate potential roadblocks, ensure the financial feasibility of any venture and create realistic projections for the next three years.

Assuming High Rates of Customer Acquisition

When developing cash flow projections, it’s also important to be realistic when it comes to customer acquisition. As with any business venture, there will be a certain amount of trial and error when it comes to marketing and advertising efforts. It is important to understand that customer acquisition rates may not be as high as anticipated, as these processes often take more time to solidify. It's advisable to leave some room for contingencies in one’s projections in order to ensure sustainable growth.

Inadequate Investor Research

Before investors are willing to put money into a business, they want to see projected cash flow, both long-term and short-term. It is important, therefore, to put together a 3 year cash flow projection that is reflective of accurate financial information. When putting together a 3 year cash flow projection, there are a few common mistakes that can be avoided.

One of the common mistakes made when making 3 year cash flow projections is not doing adequate research into potential investors. It is important to thoroughly research investors and recognize who may have an interest in investing in the business. A thorough review is needed not only to ensure that interested investors have been identified, but also that the 3 year cash flow projection is tailored to their interests.

Another mistake that may be made is failing to know what potential investors are looking for when evaluating a 3 year cash flow projection. This includes understanding the investor's needs, concerns and business strategies. Understanding investors' criteria will enable entrepreneurs to create a 3 year cash flow that meets their needs, leading to an increased probability of obtaining investment capital.


Making a successful three-year cash flow projection can be a daunting task. Poor planning, inaccurate assumptions, and oversight of necessary details can result in a flawed projection that fails to accurately reflect your business’s financial position.

To avoid these common mistakes, remember to consider long-term market trends when estimating, use the previous year's financial data as a baseline for your projection, accurately account for all costs associated with the project, and include a future-proofing element when creating the projection. By following these simple recommendations, you can create an effective and accurate three-year cash flow projection that will provide a comprehensive overview of your business’s finances.
