What Is a Rolling Cash Forecast?

A rolling cash forecast is a continuously updated projection of future cash flows that covers a fixed forward horizon, typically 13 weeks, 6 months, or 12 months, that shifts forward as time passes. Unlike a static forecast, it always maintains the same length of forward visibility.

Rolling Forecast vs. Static Forecast

A static forecast is built once and updated infrequently. By mid-year, it's more artifact than tool. A rolling forecast is rebuilt continuously. Finance teams spend less time defending the original plan and more time managing toward current reality.

Common Rolling Forecast Horizons

• 13-week (90-day): standard for operational cash forecasting; detailed for short-term liquidity decisions

• 6-month: balances operational detail with medium-term planning

• 12-month: used for strategic liquidity planning and debt management

How to Build a Rolling Cash Forecast

1. Define your forecast horizon and update frequency (weekly is standard for 13-week)

2. Identify data sources: AR aging, AP schedule, payroll, tax payments, debt service

3. Categorise cash flows by type (operating, investing, financing)

4. Establish a review and variance analysis cadence

5. Automate data ingestion where possible
