Forecast a sprint
Once you’ve completed a sprint or two, you can use the velocity chart to forecast how much of your backlog you’ll finish each sprint.
From the backlog page, open the velocity chart.
In the chart, you can see how many story points (or whatever you use to estimate your backlog) your team has completed in the previous sprints.
Go back to the backlog page, turn forecasting on, and enter your predicted velocity.
Forecast lines show how much work your team should be able to complete in future sprints.
