Stress Test Sensitivities

Properly running a stress test on your 3 way financial model is essential to ensure the accuracy and integrity of your results. Implementing scenarios with base assumptions, paying attention to relations between variables, and considering how variations can alter the outcome, can help you improve the accuracy of your model.

Run scenarios with base assumptions

Running scenarios with your model's base assumptions is a critical component to stress testing your model. Comparing these scenarios, such as varying levels of revenue and expenses, to an unchanged base case, can provide you with valuable insights on how the model may behave under different market forces.

Pay close attention to correlations between variables

It is also essential to take a close look at the correlation between different variables. Identifying what relationships impact the outcome can help you better understand your model's performance. For example, gauge the impact of changing existing assumptions, such as changes to your customer retention rate, on your model's overall result.

Consider how variations can alter the outcome

Finally, taking into account variations that might occur can help you refine and improve the accuracy of your 3 way financial model. For instance, think about what would happen if the cost of goods sold rises significantly, or the customer lifecycle changes unexpectedly. By considering these potential changes in advance, you can better determine the avidity of your model.


Utilizing Aggregate and Detailed Assumptions

Financial models are essential tools for businesses to understand the company’s financial health and performance. Improving the accuracy of a three-way financial model should be an ongoing priority. By breaking out detailed assumptions at the most granular level, monitoring trends, and using averages for key metrics, businesses can improve the accuracy of their financial models and ensure a strong financial foundation.

Breaking out Detailed Assumptions at the Most Granular Level

Creating detailed assumptions at the most granular level is an important step for improving the accuracy of a financial model. This includes breaking out assumptions for both sales and costs by product line, product, geography, or customer segment. This will help the business understand and anticipate future financial performance.

Monitor Trends and Use Averages for Key Metrics

Monitoring trends and using averages for key metrics is important for improving the accuracy of a three-way financial model. The business should identify key metrics, such as sales growth, inflation, and exchange rates, and track these over time. Analyzing these trends will help the business identify opportunities or risks in the current market and make more accurate projections.

Avoid Creating Overly Complex Model

Finally, it is important for businesses to avoid creating overly complex models. Too much complexity can lead to inaccurate results and inaccurate decision making. The business should strive for the most simple, but accurate model possible. This will help the business efficiently understand financial results, identify trends, and plan for the future.


4. Double Check All Inputs

Careful and regular evaluation of inputs is a crucial step to ensure the accuracy of your 3 way financial models. Without accurate inputs, it is impossible to achieve reliable results.

a. Always double and triple check inputs

Never ever forget to double and triple check all inputs before you finalize your 3 way financial model. This is important because any small errors in inputs will significantly affect its accuracy in the long run. Think of inputs as the building blocks of your model, and its accuracy depends on the accuracy of its components.

b. Make sure assumptions are defensible from a business standpoint

Assumptions are an important component of any 3 way financial model, but it is also essential to make sure that all assumptions served a meaningful purpose for the business. Before making any assumptions, it is important to clearly understand their purpose and ensure that they can be justified from a business standpoint.

c. Reference external data to validate accuracy

When developing a 3 way financial model, it is always a good practice to reference external data to validate its accuracy. This could include referencing relevant industry data, current market trends, etc. Not only will this help to ensure the accuracy of your model, but it will also add an extra layer of credibility to your work.


Check Outputs Against Established Limits

When building a 3-way financial model, it's important to ensure that outputs are consistent with established performance levels and expectations. Effective output evaluation requires something of a balancing act between setting too stringent limits and setting them too lax. Below are some tips for striking the right balance.

Establish Limits Based on Past Performance and Industry Benchmarks

Establishing limits is key to effectively monitoring your 3-way financial model's output. For example, if the model is predicting revenue over a certain period, you need to determine a ceiling or target of acceptable performance. This ceiling can be set based on either past performance or comparative industry benchmarks, depending on which makes more sense for your specific situation.

Monitor Threshold Levels and Compare Them to Results

Once the limits have been established, it’s important to monitor the threshold levels. This can be done on a regular basis, typically month-to-month or quarter-to-quarter. Compare the outputs from the model to the limits, and if a limit is exceeded or under-performs, adjust the model accordingly.

Continually Evaluate Assumptions and Model Structure

It’s also important to continually evaluate the assumptions and model structure. This should be done on an ongoing basis to ensure the model is producing updated and reliable outputs. Some considerations include reviewing financial assumptions, evaluating the current level of debt and equity, assessing the current market environment, and ensuring any changes to the model are documented and well-understood.

By setting established limits, monitoring threshold levels, and continually evaluating assumptions and model structure, you can improve the accuracy of your 3-way financial model and better monitor its output.


6. Understand the Model's Limitations

When using a 3 way financial model to make decisions, it is important to understand potential limitations. This can help ensure that you are making informed decisions that are in line with your financial health.

a. Keep model limitations top of mind

When using a 3 way financial model, it is critical to keep the assumptions and limitations of the model top of mind. A 3 way financial model is often built on assumptions that may not be accurate or reflect reality. Keeping limitations top of mind allows you to adjust your decision-making based on the realities of the situation, rather than relying solely on the model.

b. Understand the model is only as good as assumptions and data

When leveraging a 3 way financial model, it is important to understand that the model is only as accurate as the assumptions and data that are used to build it. If the assumptions and data are incorrect, inaccurate, or outdated, the model will be of limited value. Therefore, it is important to be vigilant about ensuring the accuracy of assumptions and data.

c. Reassess assumptions and revise models as needed

It is also important to periodically reassess existing assumptions and revise models as needed. As circumstances in the financial environment change, existing assumptions and models may no longer be valid and need to be adjusted. By regularly reassessing assumptions and revising models accordingly, you can ensure that your 3 way financial models remain reliable and that you are making informed decisions.
