Decide What Should Be Included in Financial Model

Building an accurate financial model for a startup is an essential step for any entrepreneur. A financial model is a sophisticated spreadsheet created to track, predict, and estimate the profitability and cash flow of the startup. A great financial model will provide a clear overview of the key metrics and assumptions that should be taken into consideration while running the business. In order to build an accurate financial model, it is important to first decide what should be included.

Relevant expenses and income streams

When building the financial model, it is important to include all relevant expenses that are associated with running the business. This includes options such as labor costs, cost of materials, marketing, research and development expenses, overhead, interest expenses, and more. These should be included in the model with accurate estimates for each item.

It is also essential to include all relevant income streams in the financial model. This includes sales from all product lines, services, and other sources of revenue. These should also be estimated accurately, taking into consideration the past performance of the business and potential changes in the future.

Estimated timeline for big milestones

Another important element to include in a financial model is an estimated timeline for big business milestones. This includes important events such as product launches, opening of new locations, expansion, and more. Having a timeline with estimates for when each of these events will occur allows for more accurate forecasting of the company’s future cash flow and profitability.

Estimating the timeline for big milestones also allows entrepreneurs to identify potential problem areas that could impact the company’s performance. Having this insight allows entrepreneurs to mitigate potential risks and plan for a successful future.

Choose Software Tool

Creating an accurate startup financial model requires an effective software tool. This software tool must be able to integrate multiple data sources, provide an easy to use user interface, and provide a polished analyst’s presentation.

Integration of Data Sources

Finding an appropriate software tool begins with analyzing the data sources available. Assessing the type and format of the data sources will allow you to find a software tool that can effectively integrate all of the sources into one streamlined workflow. Look for software tools which allow you to connect various data sources, including direct connections to databases and can accommodate multiple data formats.

User Interface and Presentation

Once the data sources are integrated and the financial model is built, you may have to present the model to stakeholders. Look for a software tool which provides an intuitive and easy to use user interface. The user interface must be able to display the financial model in an organized format and also allow for quick changes as necessary. Additionally, you can use the presentation feature of the software to create more dynamic slides for stakeholders.

Furthermore, the presentation should be polished. A visually appealing and professional looking presentation can help engage stakeholders, especially if the stakeholders are not knowledgeable about financial models. Look for software tools with high quality graphics, the ability to quickly modify colors and backgrounds to match a company’s branding, and options to export the presentation into multiple formats.

Finding the right software tool to build a financial model is essential, as it sets the foundation for future accuracy and clarity. With the right tool, integrating data sources, creating an easy to use user interface, and providing a polished presentation, you can create a financial model that can provide great value to stakeholders.

Gather Sources of Data

In order to create an accurate startup financial model, it is important to collect the necessary data. There are several sources of data that you can use when building a startup financial model. These include banks, credit cards, and government entitlements.


In order to get the most accurate data for your startup financial model, you should use the most up-to-date information from your bank. This includes current balances, interest rates, and fees for credit and debit cards. You should also keep track of any recent transactions that have taken place to ensure the accuracy of your model.

Credit Cards

Another source of data that can help you build an accurate startup financial model is your credit cards. Specifically, you should look at the statements and activity associated with any credit cards you have. This will give you an idea of how much you are spending and how much money you have available for financing your startup.

Government Entitlements

Finally, government entitlements can help you build an accurate startup financial model. There are a variety of government programs that can help entrepreneurs get access to the capital they need to start or expand their business. You should research the various programs available to you and determine if any of them can help you finance your startup.

Pull Data for the Model

The fifth step in building an accurate startup financial model is to pull in the data. This includes estimating future figures and adding them into software.

Estimate Future Figures

When estimating future figures, it is important to take into consideration historical data and industry trends. This will help to make the estimations more accurate and give a better indication of what the future could look like.

You should also consider any potential risks involved and factor them into your estimations. This will help to provide a more realistic outlook of what to expect.

Adding Into Software

Once the estimations for the future figures have been made, the next step is to add them into the software. This will help to ensure that the model is accurate and dynamic.

The software used should be able to handle complex calculations, as well as handling large amounts of data. It should also be able to easily integrate with existing systems and provide dynamic reporting capabilities.

Once the figures have been added into the software, the model should be tested to ensure that it is accurate and reliable. This will help to ensure that the model is as accurate and useful as possible.

Analyze and Adjust Model

An accurate startup financial model should be built in understanding the dynamics of the business that can predict the changes in the financials. The analytical process allows to pull out potential scenarios from the accurate model. Additionally, it provides early warnings of changes that need to be made and events to watch out for. To analyze and adjust, there are two key steps to consider: sensitivity and monitoring.

Consider Sensitivity

Sensitivity analysis helps to determine how changes in data can affect the results of the financial model. This is a great way to identify parameters and user inputs that are driving certain results. It is important to understand the impact of changes in the model and develop scenarios such as revenue and cost growth. Running through various scenarios of the model, analyzing their impact on the financials and adjusting the model to suit best can help to develop an accurate model.

Monitor Inputs and Projections

It is important to constantly monitor and update inputs and projections as the business evolves. There is always an opportunity for improvement. Performing regular reviews on the model will ensure that it is up to date with the latest data from the business. Additionally, review the existing model holistically and compare the current version to the one used previously to make sure the assumptions are still relevant.

  • Review the inputs for any changes in trend
  • Check any current or upcoming events and their impacts
  • Evaluate the assumptions used and make changes as necessary


Building an accurate financial model for your startup is no small task. Planning ahead can save you both time and money as you figure out a plan to get your business up and running. Laying out KPIs and projecting possible return on investment can help guide you and your team in the right direction.

Summary of the Process

At a high level, the process involves analyzing your current situation and setting up the appropriate KPIs for your business. You must also understand the various stages of your business’s growth before mapping out a multi-year financial model. Then, with your KPIs and optimized financial model in hand, you can begin to secure investments.

Final Thoughts and Tips

  • Set clear and realistic goals/expectations both short-term and long-term.
  • Allocate enough resources to complete the process effectively.
  • Ensure that all assumptions and key figures are backed up and well-supported.
  • Take advantage of software tools to streamline the entire process.
  • Get third-party advice while constructing your process.

Building a financial model that is both realistic and accurate is not an easy task, but when done correctly can be a huge asset to your business. Having an accurate financial model in place will allow you to make better informed decisions, enabling you to take your business to the next level.
