Step-by-Step Guide to Creating a Cash Flow Projection

If you have an efficient cash flow projection you are able to manage the finances of your business more effectively. Underneath is a step by step guide on how to create a cash flow projection. 

Choose which projection model is best suited to your business based on the needs and planning requirements of your business. 

Take the following things into account when deciding on the most appropriate projection model. 

Step 1: Choose the type of projection model

Short-term projections: These projections cover around 3-12 months and typically used when doing immediate planning monitoring.

Long-term projections: These projections look past the first 12 months and give you insights that are useful in strategic decision-making and planning for the future. 

Combination approach: By combining short and long-term projections you can take care of  both immediate and longer range goals. .

Step 2: Gather historical data and sales information

  • Gather up all historical financial data such as the amount of cash coming in and going out of the business in previous periods. 

  • Examine sales information, taking seasonality, customer payment patterns, and market trends into account.

Pro Tip: Accounting software is routinely used by finance teams to help them get a clear understanding of historical and transactional data.

Step 3: Project cash inflows

  • Work out what cash will be coming into the business by using sales forecasts and taking into account things like payment terms and collection periods

  • Make use of historical data and market insights to get more accurate projections.

Step 4: Estimate cash outflows

  • Identify components that make up your cash outflow then put them into categories like operating expenses, loans that need repaying, payments to suppliers, and tax liabilities.

  • Make use of  historical data and expense forecasts to work out the timing and total of your cash outflows.

Pro Tip: By using your cash flow statement as a reference point you are able to pinpoint the source of cash that goes in and out of your business. 

Step 5: Calculate opening and closing balances

  • Calculate what your opening balance is for each period, which will tell you how much cash you have available at the start of the period

Opening Balance = Previous Closing Balance

  • Work out your closing balance by looking at the opening balance, then what cash you expect to come into the business and your cash outflow for the same period.

Closing Balance = Opening Balance + Cash Inflows – Cash Outflows

Step 6: Account for timing and payment terms

  • Look at when cash inflows and outflows are expected to create a cash flow timeline that is realistic. 

  • Take the payment terms you have with customers and suppliers into account so cash movements can be aligned with the projection. 

Step 7: Calculate net cash flow

  • Work out your net cash flow for each period which is the difference between the cash coming into the business and how much goes out. 

Net Cash Flow = Cash Inflows – Cash Outflows

Pro Tip: it is crucial for your business that you calculate your net cash flow for every period so you can get a view of your future cash position.  Look at it as calculating your future cash flow. 

Step 8: Build contingency plans

  • By incorporating a contingency plan you can allow for unexpected events that could impact cash flow like late payments and economic downturns. 

  • Build a buffer into your projection to cater for any unforeseen circumstances. 

Step 9: Implement rolling forecasts

  • Utilise rolling forecasts in which you make regular updates and refinements to your cash flow projections which you can base on actual performance and any changes in circumstances. 

  • Rolling forecasts give you a dynamic view of your cash flow that allows for  adjustments and enhanced accuracy.


How to Calculate Projected Cash Flow

To determine projected cash flow, begin by estimating the cash inflows from sources such as sales revenue, investments, and financing activities. Next, subtract the anticipated cash outflows, including operating expenses, loan repayments, taxes, and capital expenditures. The resulting net cash flow provides a clear picture of the cash the business expects to generate or spend during the specified period.

Calculating projected cash flow is essential for businesses to assess their future financial position and make strategic decisions. This process involves predicting cash inflows and outflows over a defined period by analysing historical data, sales estimates, expense projections, and other relevant factors. Regular updates and reviews of cash flow projections enable businesses to identify potential cash shortfalls or surpluses, supporting proactive financial planning and effective cash management strategies.


6 Common Pitfalls to Avoid When Creating Cash Flow Projections

If you take a more in depth look at why some cash flow projections fail you will find that one of the main reasons is that quite a lot of companies choose projection models that are not only unrealistic but don’t actually mirror how their finance department works.  unrealistic projection models that don’t mirror the actual workings of their finance department.

 

Six common mistakes made by companies when creating a cash flow projection are

  • Unrealistic assumptions

  • Overestimating Collections and Payables

  • Inaccurate Sales Timing

  • Lack of Scenario Planning

  • Overlooking Seasonal Cash Flow Patterns

  • Ignoring Contingencies and Unexpected Events

Any cash flow projection will only be as good as the data used to create it. You can never be absolutely sure well in advance whether unexpected events will occur further down the line. If your aim is to achieve more accurate results then it is imperative that your cash flow projection is realistic. It is important that any key assumptions are not optimistic. Make sure you keep to likely numbers when making a projection. 

A variance of 5% is acceptable but if you exceed this threshold you need to take a more in depth look at the key assumptions you are making. Highlight any flaws that could be compromising the accuracy of your projection. These are some insights into the pitfalls that have been provided by finance executives with real world experience. 

 

Sales Estimates:

Avoid sales forecasts that are overly optimistic, as they can lead to your cash flow projections being less accurate. Keep sales projections grounded in reality to ensure your cash flow estimates remain dependable.

 

Accounts Receivable:

Accurately reflect your customers' payment habits in your projections, especially if they routinely pay at the end of a 30-day term. Align your cash flow timelines with actual payment behaviors to improve accuracy.

 

Accounts Payable:

Include recurring annual and quarterly expenses in your accounts payable estimates. Be mindful of potential changes, such as shifts in tax rates, especially if your business is approaching a higher tax bracket.

 

Cyclical Trends:

Factor in seasonal variations and industry-specific trends when creating cash flow projections. Use historical data to identify patterns and adjust your forecasts to account for these recurring fluctuations.

 

Contingencies and Unexpected Events:

Prepare for the unexpected by building contingencies into your projections. Unforeseen events, such as economic slowdowns, natural disasters, or market shifts, can disrupt cash flow—so incorporate financial buffers to minimize risks.

 

Scenario Planning:

Relying on a single projection can leave your business vulnerable to unforeseen challenges. Develop multiple scenarios, including best-case, worst-case, and moderate outcomes, to evaluate how different situations could impact cash flow.

 

By recognising and addressing these common pitfalls, you can implement best practices to create more accurate and effective cash flow projections. Stay proactive and ensure your forecasts reflect the realities of your industry and market conditions.


How Automation can Help you Project Cash Flow

Setting up a cash flow projection chart is just the starting point: the real benefits are the insights that it will give you. As important as cash flow projections are, traditional methods can take up a lot of resources which can have an adverse effect on productivity. 

But don’t worry a solution is available in the guise of a cash flow projection chart automation tool.

Finance professionals are well aware of why automation is required but you need to invest time and money in the project. It is easy to build a case for automation especially if a company is looking to prioritise cash reporting and forecasting and wants to benefit from day to day cash management and investment planning. 

Have a look at 3 different examples that will show that the benefits of automated cash flow projections will far outweigh the cost of implementing it. 

Scalability and Adaptability: Managing cash flow using spreadsheets may work well in the early stages of a business, but as your operations expand, it becomes increasingly complex and time-consuming. Manual cash flow processes often fail to keep pace with the growing volume of transactions and an expanding customer base. Many businesses rely on temporary fixes that address immediate issues but overlook long-term sustainability. To ensure efficiency, your business needs an automated solution that scales seamlessly alongside growth and adapts to changing demands. Additionally, with customisable features, you can tailor cash flow projections to meet your unique business needs and respond effectively to shifts in market conditions.

Time savings: Consider a simple example of the time and effort involved in compiling a 13-week cash flow projection for stakeholders every week. The process typically includes: 

  • Capture cash flow data from banking and accounting platforms and classify transactions.

  • Create short-term forecasts using payables and receivables data.

  • Model budgets and other business plans for medium-term forecasts.

  • Collect data from various business units, subsidiaries, and inventory levels.

  • Consolidate the data into a single cash flow projection.

  • Perform variance and sensitivity analysis.

  • Compile reporting with commentary.

This process on its own can take up a large number of hours every week. For example if we assume it takes six hours for one resource and an additional 6 hours for extra contributions that equates to 12 hours a week or 624 hours a year. If you implement an automated tool for cash flow projections it removes the need for time consuming manual jobs like logging in, downloading data, updating spreadsheets and putting together reports. By automating this type of task you will save your team numerous hours which allows them to focus on activities that are more valuable to your organisation. 

Accuracy and Efficiency:

Precision is critical for effective cash flow monitoring and forecasting, as it directly impacts risk management. However, relying on manual data processes increases the likelihood of human error, which can carry serious financial consequences for businesses. Common challenges include:

  • Poor financial decision-making

  • Cash flow unpredictability

  • Heightened financial risks

  • Loss of stakeholder trust

  • Wasted time and resources

  • Compliance and reporting issues

  • Inconsistent data handling

Implementing automated cash flow solutions addresses these risks by delivering accurate and dependable results. Automation tools ensure consistency through real-time data integration, error detection, and validation processes, enhancing both accuracy and confidence in cash flow projections.
