Herein, how story points are calculated in agile?

Once determined, sizing of all the user stories should be initiated by comparing them against the baseline. While estimating story points, we assign a point value to each story. Relative values are more important than the raw values. It should also be two-thirds of a story that is estimated 3 story points.

Beside above, how do you estimate a user story? Story Estimation Tips:

1. Use at least four values during the session.
2. Give your team an out if they just don't know.
3. Let the team doing the work conduct the story estimation before they commit.
4. Everyone on the team gives an estimate.
5. Set a maximum story/feature/epic size based on the time boundaries.
6. No Zeros.

How do story points work?

Story points are a unit of measure for expressing an estimate of the overall effort that will be required to fully implement a product backlog item or any other piece of work. When we estimate with story points, we assign a point value to each item. The raw values we assign are unimportant.
