Learn how to create a financial model for your business using historical data. This step-by-step guide is perfect for small businesses and startups that have been operating for a few years.
A financial model is essentially a map of your business's financial future. It’s a tool that allows you to project revenue, expenses, cash flow, and profitability over time. Think of it as your business’s crystal ball—except it's powered by numbers, not magic.
Here’s why it matters:
Before we jump into building one, let's break down what you'll need to create a financial model for your business. This article is focused for businesses who already have been at business for at least a year. For businesses who haven't launched yet, we'll be creating a separate post.
Your financial model should start with the basics—your historical financial statements. These documents provide the data foundation for all projections and insights. Here’s what you need to include:
If you don't have any of these statements, then you should probably spend some time putting them together. Technically you can create a financial model with just a Profit and Loss statement but we don't necessarily recommend it.
Once you have your historical data in a good spot you want to consider the goal of your financial model.
These are all examples of different ways financial models can be used for businesses.
Now that you have your data and goals in mind, you're ready to build your model. The quickest way to do this is to fire up Excel or Google Sheets. However, Kordis also offers forecasting software that you may prefer if you're anti-spreadsheet.
The income statement (also known as the Profit and Loss or P&L statement) is the heart of your financial model. It’s where all forecasting—revenue, expenses, and ultimately profitability—comes together. By using your historical P&L as a starting point, you can create projections that guide your business strategy.
Here’s how to structure your projections within the P&L:
Forecasting revenue starts at the top of the income statement. Here’s how to approach it:
Expenses are the next major section of your P&L. To make accurate forecasts, separate your costs into two categories: Cost of Goods Sold (COGS) and Below-the-Line Expenses.
COGS are the direct costs associated with producing your goods or delivering your services. This includes materials, labor, and other costs that scale with your revenue. Here’s how to project it:
Below-the-line expenses are the operational costs that support your business but aren’t directly tied to revenue generation. These include categories like rent, salaries (for non-production roles), marketing, and utilities. Here’s how to forecast them:
Once you’ve forecasted revenue, COGS, and below-the-line expenses, calculate your Gross Profit and Net Profit:
Example:
If revenue is $100,000, COGS is $40,000, and below-the-line expenses are $45,000:
Forecasting directly within the income statement format ensures that your projections are:
When projecting COGS, think of it as a percentage of revenue that scales with your sales. This approach ensures your forecasts reflect the true cost of delivering goods or services as your business grows.
Building a financial model may seem complex at first, but by grounding it in your Income statement, you can create a simple, structured, and reliable forecast for your business’s future. By focusing on revenue projections, Cost of Goods Sold (COGS), and below-the-line expenses, your model provides a clear snapshot of your profitability and helps you make informed decisions.
Here’s what you’ll gain:
However, the success of this approach depends on one crucial factor: accurate historical data. If your bookkeeping isn’t up to date or your records are incomplete, your financial model will be flawed from the start. Good bookkeeping forms the foundation of accurate forecasting—without it, even the best financial model will fall short.
That’s why it’s vital to have a reliable bookkeeper or accounting system in place. At Kordis, we understand the importance of clean and accurate financial data.
