Sensitivity Analysis

Sensitivity Analysis: Stress-Testing Your Business Plan

Learn how to stress-test your financial projections by changing key assumptions. Discover which variables have the most impact on your business and build robust plans that withstand uncertainty.

Sensitivity analysis tests how changes in key assumptions affect your financial outcomes. By identifying which variables have the most impact on your business, you can focus risk management efforts, build more robust plans, and demonstrate to investors that you understand your business dynamics.

Key Variables to Test

Revenue Drivers

Customer acquisition rate, average deal size, conversion rates, pricing changes, and churn. A 10% change in any of these can dramatically alter your projections.

Cost Variables

COGS percentage, CAC trends, hiring costs, software subscriptions, and office expenses. Small changes in variable costs compound over time.

Market Conditions

Market growth rate, competitive pricing pressure, interest rates, and regulatory costs. External factors you cannot control but must plan for.

Timing Assumptions

Sales cycle length, product launch dates, funding timelines, and hiring ramp-up. Delays of 3-6 months can significantly impact runway.

How to Run Sensitivity Analysis

  • Identify key assumptions in your financial model and rank them by uncertainty and potential impact
  • Create a data table with best, expected, and worst-case values for each variable
  • Measure output impact on revenue, gross margin, EBITDA, and cash runway
  • Build tornado charts to visualize which variables create the most volatility
