Three Common Mistakes Founders Make
in Financial Models

Treating Financial Models as "Homework"

Too often, founders treat financial models like a checklist item to impress investors. This mindset undervalues their real purpose: driving operational decisions and strategic planning. A financial model isn’t just for showing off; it’s a tool to ensure your business thrives.

Overcomplicating the Model

Including too many variables or unnecessary details results in models that are cumbersome and hard to update. For example, a founder planning their budget added detailed forecasts for 10 different marketing channels without having data to support their performance. When the team focused only on two key channels that drove results, they found the model overcomplicated and largely irrelevant. Simplicity ensures your model is both useful and actionable.

Growth-Based Model

Many founders fall into the trap of relying on simple growth-based models, where they project a fixed percentage increase in key metrics like revenue, usually based on assumptions like "revenue will grow by 10% every month." While this approach can seem easy and optimistic, it ignores the critical factors that truly drive growth in a startup.

Why Your Financial Model Needs to Be Driver-Based

The Challenges Founders Face Building a financial model often means grappling with overestimated growth, ignored variables, or disconnected activities. These challenges make creating a realistic and actionable model difficult.

What Is a Driver-Based Model? A driver-based model solves these issues by linking inputs (like ad spend or pricing) to outputs (like leads or revenue). This ensures every assumption mirrors how your business truly operates.

How to Build a Driver-Based Model:

• Identify Key Drivers: Focus on elements that directly affect results—leads from ad spend, conversion rates, or average deal size. Don’t assume revenue grows by 10% monthly; instead, ask, “What specific actions will drive this growth?”
  

• Link Drivers to Measurable Actions: To set the stage, consider how decisions like increasing your marketing budget or adjusting pricing strategies play out in real-world outcomes. For example, "If I double my marketing budget, I expect to generate 500 more leads because my past performance shows a cost-per-lead of $20. If my conversion rate is 10%, this should result in 50 new customers." This narrative ensures your projections are grounded in real data and clarifies the impact of specific actions on your business outcomes.
  

• Make Projections Actionable: Ensure your model shows what adjustments are needed. If leads increase, can your sales team handle them? If marketing scales, can operations keep up without extra costs?

Keep It Flexible Business conditions change. With a driver-based model, you can quickly adapt your inputs to reflect shifts in strategies or markets, ensuring your forecasts remain accurate and useful.
