What functionality should be used to predict ongoing revenue for the next three months?

The correct functionality to predict ongoing revenue for the next three months is to add a forecast with a forward period of approximately 90 days. This option directly addresses the need for forecasting future revenue based on historical data, taking into account the specific time frame of three months ahead.

In this context, it's important to understand that forecasting typically involves using historical data to project future performance. By selecting a forward period of approximately 90 days, you are effectively allowing the forecasting model to generate predictions that span the precise duration needed.

Using the forecast functionality in analytics tools generally incorporates statistical methods to analyze past trends and seasonality, which is essential for generating accurate predictions. The 90-day window aligns with the three-month target for revenue forecasting, ensuring the model captures seasonal variations and provides a realistic estimate for ongoing revenues.

Other methods, such as creating a custom calculation or simply adding a trend line, may not specifically address the need for a predictive forecast over a defined future time frame. These options may focus on general analysis or trend identification without the structured approach that a dedicated forecasting tool offers.
