Compounding of offences u/s 276b

What would be the fees for compounding of offences u/s 276B? It is said 3% per month or part of a month of the amount of tax in default. Can I take the fees as 2 times the amount of Interest on late payment of TDS as calculated u/s 201(1A)?

Can someone please share me a flowchart explaining compounding of offences u/s 276B?

Thanks in advance!
