I was curious. According to Quora these are the class ranges in India:

Affluent/Rich - Rs. 500,000 p.m and above. Usually businessmen & celebrities.

Upper class - Rs. 200,000 per month to Rs. 500,000 p.m.

Upper middle class- Rs. 50,000 p.m. to Rs. 200,000 p.m.

Middle-Middle class - Rs. 20,000 p.m to Rs. 50,000 p.m.

Lower-middle class - Rs. 10,000 p.m to Rs. 20,000 p.m.

Lower class - Rs. 6,000 per month to Rs. 10,000 per month

Poor - Less than Rs. 6,000 p.m.

By glance $10,000 per year seems like a good average. Which is 661,500 INR per year or about 55,000 per month.
