In our previous Quick Insight, we explored the benefits of scenario analysis and how it can help prepare your startup for various potential outcomes. Now, let’s delve into another powerful tool in financial modelling: Sensitivity Analysis. This technique helps you identify the key risk factors that could impact your business, enabling you to make more informed decisions and better prepare for uncertainties.

Understanding Sensitivity Analysis

Sensitivity analysis involves changing one variable at a time in your financial model to see how sensitive your results are to changes in that variable. This helps you understand which factors have the most significant impact on your startup’s financial performance and which areas require closer monitoring.

Steps to Conduct Sensitivity Analysis

Here’s how to apply sensitivity analysis to your financial modelling:

Identify Key Variables

Determine the key variables that could influence your financial outcomes. These might include sales volume, pricing, cost of goods sold (COGS), operating expenses, and interest rates. Think about which factors are most likely to fluctuate and impact your business.

Develop a Base Case Scenario

Create a base case scenario that reflects your most likely financial projections. This will serve as the reference point for your analysis. Ensure your base case is realistic and based on current data and assumptions.

Adjust One Variable at a Time

Change one variable at a time while keeping all other variables constant. For example, increase your sales volume by 10%, then by 20%, and observe how this impacts your revenue, profits, and other key metrics. Repeat this process for each variable to see how sensitive your financial outcomes are to changes in each factor.

Analyse the Results

Evaluate how changes in each variable affect your financial projections. Identify which variables have the most significant impact and which ones have minimal effect. This analysis will highlight the key risk factors that you need to monitor closely.

Benefits of Sensitivity Analysis

Sensitivity analysis offers several advantages:

• Risk Identification: It helps you pinpoint the variables that have the greatest impact on your financial outcomes, allowing you to focus on managing these key risks.
• Informed Decision-Making: By understanding the sensitivity of your financial model, you can make more informed decisions and better allocate resources.
• Improved Forecasting: Sensitivity analysis can improve the accuracy of your financial forecasts by highlighting areas where small changes can have a big impact.

Practical Example

Imagine you’re the founder of FreshBites, a startup delivering fresh, healthy meal kits. Here’s how you might conduct sensitivity analysis:

1. Identify Key Variables: Key variables might include the number of subscriptions, average order value, delivery costs, and ingredient costs.
2. Develop Base Case Scenario: Your base case scenario assumes 1,000 subscriptions, an average order value of £50, delivery costs of £5 per order, and ingredient costs of £20 per order.
3. Adjust One Variable at a Time:
   • Increase the number of subscriptions by 10% and 20% to see how this impacts revenue and profits.
   • Decrease delivery costs by 5% and 10% to observe the effect on overall profitability.
   • Increase ingredient costs by 5% and 10% to understand how rising costs could affect your margins.
4. Analyse the Results:
   • A 10% increase in subscriptions might boost revenue significantly, but if ingredient costs rise by 10%, your profit margins could be severely impacted.
   • A small decrease in delivery costs might have a notable positive effect on profitability, highlighting the importance of managing logistics efficiently.

Wrapping It Up on Sensitivity Analysis

Sensitivity analysis is an essential tool for startups, enabling you to identify and manage key risk factors that could impact your financial performance. By understanding which variables have the most significant impact on your outcomes, you can make more informed decisions, improve your forecasting accuracy, and better prepare for uncertainties.
