Have always been curious about the hourly charge of T1 firms like AZB, Trilegal, SCAM, etc. Any info?

Ranges between 10k - 15k for all the tier 1 firms.

The max rich I can be at 15000 per hour billing 3000 hours a year (10 hours a day discounting 65 days for cost) - is 4 Crore 50 Lakh, at fag end of my career. This is a huge and sufficient amount, but I don't feel this money is relevant at all.
