What Is a Financial Model?
01/10/25
A financial model is a structured representation of a business, project, or transaction — built in a spreadsheet to quantify the financial outcomes of different decisions and scenarios. At its core, it translates assumptions about the real world into numbers: revenues, costs, cash flows, returns, and value.
A well-built model isn’t just a calculation engine. It’s a decision-making tool. It answers questions like:
- If we invest £20m today, what return can we expect over the next ten years?
- How sensitive is our profit margin to a 5% increase in raw material costs?
- Can the business service its debt under a downside scenario?
- What’s this company worth, and what should we pay for it?
- When does our cash run out if revenue growth slows?
The best models are transparent enough that anyone picking them up can trace every number back to an assumption, robust enough that they don’t break when those assumptions change, and flexible enough to test the scenarios that matter to the people making the decision.
