3 Statement Model

A free guide on three statement models.

What is a 3 statement model?

A 3 statement model links the income statement, balance sheet, and cash flow statement into one dynamically connected model.  3 statement models are the foundation on which more advanced financial models are built such as discounted cash flow DCF models, mergers models, leveraged buyout LBO models, and various other types of financial models.


How do you build a 3 statement model?

There are several steps required to build a three statement model, including:

  • Input the historical financial information into Excel
  • Determine the assumptions that will drive the forecast
  • Forecast the income statement
  • Forecast capital assets
  • Forecast financing activity
  • Forecast the balance sheet
  • Complete the cash flow statement

In this guide, we will walk you through each of the above steps.  For a more detailed, video-based tutorial on how build a model from scratch, please watch our online financial modeling courses.


Input the historical information into Excel

In this step, we take the historical financial information of the company and either download, type or paste it into Excel.  Once the information is in Excel (see this free course on Excel best practices), you’ll need to do some basic formatting to make the information easy to read and follow the structure you want your model to take.

Determining the assumptions that will drive the forecast

With the historical financial information in Excel, and in an easy-to-use format, we can start calculating some metrics to evaluate the historical performance of the company.  We need to calculate metrics like: revenue growth, margins, capital expenditures, working capital terms (like accounts payable, inventory, and accounts receivable).

Forecasting the income statement

With the assumptions in place it’s time to start forecasting the income statement, starting with revenue, and building down to EBITDA (Earnings Before Interest Taxes Depreciation and Amortization).  At this point we will require support schedules to be built for capital assets and financing activity.


Forecasting capital assets

At this point we need to forecast capital assets like Property Plant & Equipment PP&E before we can finish the income statement in the model.  To do this we take last period’s closing balance, add any capital expenditures, deduct depreciation, and arrive at the closing balance.  Depreciation can be calculated in a variety of ways, such as straight line, declining balance, or percent of revenue.

Forecasting financing activity

Next up we have to build a debt schedule to determine interest expense on the income statement.  Similar to the section above, we take last period’s closing balance, add and increases or decreases in principle, and arrive at the closing balance  The interest expense can be calculated on opening balance, closing balance, or average balance of debt outstanding.  Or, a detailed interest payment schedule can be followed if available.


Forecasting the balance sheet

At this point it’s possible to complete the balance sheet in our 3 statement model, except for the cash balance which will be the last step.  Working capital items are forecasted based on assumptions around average days payable and receivable, as well as inventory turns.  Capital assets like PP&E come from the schedule above, as well as debt balances.

Completing the cash flow statement

With the balance sheet completed (except for cash) we can build the cash flow statement and complete our three statement model in Excel.  This section is essentially just linking to items that have already be calculated above in the model.  We have to complete each of the three main sections: cash from operations, cash from investing, and cash from financing.  For a more detailed explanation of how to calculate each of these sections, please check out our course, how to build a financial model in Excel.
