How to add SUM() in Views Like in the given picture

I would like to find and print the sum along with view results. How can I do that?
Try the Views Calc module

This module adds simple calculations to a views table. Requires the Views module.
You can SUM, AVERAGE, COUNT, MIN, MAX, or AVG selected columns. A plug in theme makes the view look more spreadsheet-like (right justifies numeric fields, shades calculated columns and rows, and underlines calculated rows).
