How to Create a Rolling Forecast That Works

In a fast-changing business world, traditional annual budgets often fall short. That’s where rolling forecasts come in—they give small businesses the agility to adapt quickly, respond to market shifts, and make smarter decisions with real-time insights. If you're looking to future-proof your business and boost your financial confidence, learning how to build a rolling forecast that works is a critical step.

What Is a Rolling Forecast?

A rolling forecast is a financial planning tool that updates regularly—typically monthly or quarterly—so you always have a 12-month (or longer) view of where your business is headed. Unlike static annual budgets that become outdated, rolling forecasts evolve with your business, incorporating new data as it's collected.

For example, if you’re preparing a 12-month rolling forecast and you're currently in June, you’d forecast through the following May. Next month, you’d update it to include June of the next year, and so on.

Why Use a Rolling Forecast?

Here’s why forward-thinking businesses use rolling forecasts:

• Agility: Adapt quickly to changes in revenue, expenses, and the market.

• Accuracy: Base financial decisions on the most current information available.

• Growth Readiness: Spot financial opportunities or red flags early.

• Strategic Planning: Make ongoing, data-driven decisions that align with business goals.

Steps to Create a Rolling Forecast That Actually Works

1. Define the Time Frame

Start with a 12-month window—this is the most common approach. Update the forecast monthly or quarterly, depending on your business's needs and pace.

2. Choose Key Drivers

Identify the core elements that influence your revenue and expenses. For example:

• Number of clients/projects

• Sales volume

• Cost of goods sold

• Payroll

• Overhead costs

Focusing on these drivers will help create more accurate, dynamic models.

3. Gather Historical Data

Your past financial data provides a reliable starting point. Look at trends in revenue, expenses, seasonality, and growth rates over the last 12–24 months.

4. Build Your Forecast Model

Use spreadsheet software or accounting tools to map out expected income and costs over each period. Update with:

• Actual results from the previous month

• Revised assumptions (e.g., customer acquisition rate, expense increases)

  
  

5. Incorporate Scenarios

Add scenario planning to your forecast—create best case, worst case, and most likely case scenarios to prepare for different outcomes.

6. Update Regularly

Rolling forecasts are only valuable if they stay current. Make it part of your monthly financial routine to revisit and revise assumptions.

7. Review and Adjust Strategy

Use the forecast to guide real decisions: Do you need to reduce spending? Hire new staff? Invest in a new service? Let your numbers lead the way.
