ZURICH, SWITZERLAND - November 26, 2025 - eFinancialModels has compiled insights from its network of expert financial model developers, revealing why most financial models used by lenders, investors and executives fail to support real-world decision-making, and which practices consistently produce reliable outcomes across industries.
For years, finance teams have assumed that accuracy in formulas alone leads to reliable projections. The experts behind some of the most widely-adopted financial model templates disagree. Their collective insight highlights a deeper problem: stakeholders do not trust what they cannot understand.
"Most people think financial modeling is about formulas," said Cyrill Haenni, founder at eFinancialModels. "Our vendors learned it's about solving a harder problem: turning uncertainty into decisions that stakeholders actually trust."
The Transparency Problem: Why Many Models Fail
“If someone opens your model and cannot immediately understand how assumptions flow to results, you have missed the mark,” said Pushkar Kumar, creator of the EV Charging Station Financial Model. His template converts capital expenditure, grid connectivity and regulatory incentives into actionable five-year projections.
That sentiment is echoed by Anuj Verma, developer of the Private Equity Fund Model, who emphasized clarity above all: “People appreciate that the model is easy to customize, provides clear explanations, and instantly reflects changes to assumptions.”
Professional auditors catch only 20 to 40 percent of errors during deep reviews, but stakeholder mistrust triggered by lack of clarity is even more damaging than calculation mistakes.
Beyond Theory: What Businesses Need From Models Today
Business schools teach discounted cash flows. The real world demands frameworks that model operational drivers such as MW capacity, PUE ratios, availability of power, fleet utilization, or loan cohort behavior in a way that supports fundraising, valuation and banking requirements.
Giorgos from Profit Vision developed the Similarly, Jason Varner, developer of the Lending Model Startup Forecast, created a model that supports scenarios of varying loan tranche sizes and capital requirements over time, a problem many lenders previously tried solving manually.
The Solar BESS Financial Model, prepared by eFinancialModels founder Cyrill Haenni, helps quantify savings in electricity costs and price arbitrage opportunities when adding battery storage to solar parks.
Five Principles That Consistently Produce Models That Work
Across sectors, the insights converge into five principles that define successful financial modeling:
-
Transparency builds trust. If stakeholders cannot follow logic, they reject the output.
-
Structure enables flexibility. Usability matters more than complex math.
-
Industry-specific drivers are essential. Generic templates miss critical realities.
-
Speed and credibility can coexist. Reusable frameworks reduce risk and save time.
-
Models must drive decisions, not calculations. Business outcomes matter most.
