Let’s take an example.

Team capacity is calculated as per people availability in that sprint.

Capacity Requirements Planning. For you to commit to a sprint goal, you need to know current team capacity. As the name implies, the process can be split into two parts: capacity and planning. We need to have a realistic view of how much work can be done by our team next month, taking into account the availability of each of our team members during the month.

How to plan for the team capacity?

This will allow us to commit to our leadership on deliverables’ scope and if needed ask for more resource or to reduce the deliverables. Here's how to create a capacity plan for your team, with your team.
Related to capacity planning is capacity requirements planning, which is when an organization decides how much it needs to produce and whether it is capable of doing so. Capacity planning takes the guess-work and assumptions out of your project timeline. I ask teams to do commitment driven planning during early stages of scrum adoption. We are responsible for planning our team’s capacity every month. Capacity planning is the process of identifying how many hours a project or task will require, determining whether or not your team has the available bandwidth to complete it, and then coordinating that work for maximum efficiency.

Therefore, capacity requirements planning allows companies to meet supply and demand.
