Financial Models: Bet Your Money Without One?

Opinion:
Financial modeling might sound intimidating, but it’s an essential skill for anyone making serious financial decisions. Forget the hype about “gut feelings” and “intuition.” If you want to understand a business, project future performance, or make informed investment choices, financial modeling is non-negotiable. Are you truly prepared to bet your money on anything less?

Building Blocks: What Goes Into a Financial Model?

At its core, a financial model is a representation of a company’s financial performance, both past and projected. It’s built in a spreadsheet program (usually Excel or Google Sheets) and uses formulas to link various assumptions and inputs to generate financial statements. These statements typically include the income statement, balance sheet, and cash flow statement.

The process begins with historical data. You need to gather at least 3-5 years of a company’s financial statements. You can usually find these in their annual reports (10-K filings for public companies with the SEC). Once you have the historical data, you can start making assumptions about the future. This is where the art and science of financial modeling come together.

What assumptions are we talking about? Revenue growth is a big one. What do you expect the company’s sales to do over the next few years? What about cost of goods sold (COGS) and operating expenses? Will they stay in line with historical trends, or do you anticipate any changes? These assumptions are the engine that drives the entire model. Leaders with a smarter strategy know how to turn data into growth.

Here’s what nobody tells you: garbage in, garbage out. If your assumptions are unrealistic or based on flawed logic, your model will be worthless. That’s why it’s so important to do your homework and understand the business you’re modeling.

Scenario Planning: Stress-Testing Your Assumptions

Once you’ve built your base case model, it’s time to start thinking about different scenarios. What happens if your assumptions are wrong? What if revenue growth is slower than you expected? What if expenses are higher? This is where sensitivity analysis comes in.

Sensitivity analysis involves changing key assumptions in your model and seeing how they affect the results. For example, you might create a “best case” scenario where revenue growth is higher than expected and expenses are lower. You might also create a “worst case” scenario where the opposite is true. By comparing these different scenarios, you can get a better sense of the range of possible outcomes.

I once worked on a project for a local Atlanta-based manufacturing company where we were modeling a potential expansion into a new product line. The initial model, based on management’s rosy projections, showed a huge return on investment. However, when we ran a sensitivity analysis and considered a scenario where raw material costs increased by 15%, the project became unprofitable. This forced the company to re-evaluate its plans and negotiate better terms with its suppliers. This is why efficiency is important for Atlanta businesses.

Remember, the goal of scenario planning is not to predict the future with certainty. It’s to understand the risks and opportunities associated with different outcomes.

Free Cash Flow: The Key to Valuation

Ultimately, the purpose of financial modeling is often to determine the value of a business. And the most important output of a financial model for valuation purposes is free cash flow (FCF). FCF represents the cash that a company generates after paying for all of its operating expenses and capital expenditures. It’s the cash that’s available to be distributed to investors (either through dividends or share repurchases).

There are different ways to calculate FCF, but the most common approach is to start with net income and then add back non-cash expenses like depreciation and amortization. You also need to subtract capital expenditures (the money the company spends on property, plant, and equipment) and any increases in working capital (the difference between current assets and current liabilities).

Once you have a forecast of FCF for the next several years, you can use it to estimate the present value of the business. This involves discounting the future FCFs back to today using a discount rate that reflects the riskiness of the business. The higher the risk, the higher the discount rate.

Here’s a limitation to acknowledge: determining the appropriate discount rate is as much art as science. It requires judgment and an understanding of the company’s industry, competitive landscape, and overall financial health. Don’t just pull a number out of thin air. To stay ahead of rivals, know your rivals.

Counterarguments and Why They’re Wrong

Some might argue that financial modeling is too complex or time-consuming for the average person. They might say that it’s only necessary for professional investors or financial analysts. I disagree. While it’s true that building a sophisticated financial model can be challenging, the basic principles are relatively straightforward. And even a simple model can provide valuable insights.

Others might argue that financial models are inherently inaccurate because they rely on assumptions about the future, which is inherently uncertain. While it’s true that no model can perfectly predict the future, that doesn’t mean they’re useless. Models can help you think through different scenarios, identify potential risks and opportunities, and make more informed decisions.

Besides, what’s the alternative? Flying blind? Making decisions based on hunches? That’s a recipe for disaster. I’ve seen too many businesses in the Marietta area fail because they didn’t bother to do even basic financial planning.

Financial modeling is not about predicting the future; it’s about preparing for it. A tech tsunami could sink your business if you aren’t ready.

Financial modeling is a skill that anyone can learn, and it’s a skill that can pay off handsomely. Start small, focus on the basics, and don’t be afraid to make mistakes. The more you practice, the better you’ll become.
