Rolling Forecast
What is a rolling forecast?
A rolling forecast is a forecast that is updated regularly, usually monthly or quarterly, and always looks a set number of periods ahead. As each month ends, a new month is added to the end so the forecast never runs out.

How it works
- Choose a horizon, such as the next twelve months
- After each close, replace the forecast with actuals and add a new period at the end
- Review changes in assumptions with the team, see budget vs actual analysis
Why it matters for service firms
Annual budgets go stale quickly when work and staffing change. A rolling forecast keeps owners looking ahead and makes cash and hiring decisions easier to time.
Frequently asked questions
How is a rolling forecast different from a budget?
A budget is usually set once for the year and compared against results. A rolling forecast is refreshed regularly and always covers the same number of future periods. Many firms use both.
How detailed should a rolling forecast be?
Keep it as simple as will be maintained. Revenue by service, payroll, and major costs are enough for most small firms. Detail that no one updates adds effort without improving decisions.
