Here we provide you an example for the plinth area calculation. Plinth area is calculated by adding all the net area that include in the plinth area calculation.

How to Calculate Plinth Area of a Building?
Step 1: Consider a beautiful two store building with the ground floor net plinth area of 92.10 Sq.m. Its net plinth area of first floor is 90.30 sq.m.
Given values here was
Net plinth area of ground floor - 92.10 Sq.m
Net plinth area of first floor - 90.30 sq.m

Step 2: Add all the plinth area specified to get the net plinth area.
Net plinth area = 92.10 + 90.30 sq.m
= 182.40sq.m

Note the following while calculating the plinth area.
→ Not includes area open to sky
→ Car parking is included
