Considering a retail spend of 10k on amazon.
5% CB would result in 10k*0.05 = 500 INR statement credit
With the new reward structure, it would yield 10k*4*5/150 = 1333 RPs. 4 RPs for every 150, and 5x is the factor.
In case of regalia 0.2 is the factor for redeeming rewards to statement credit, so 1,333 gives 266INR if we go for statement credit.
also consider that previously we were getting 1x RP +5% cashback now we get only 5x RP.
so in reality we are getting 4x RP in exchange of 5% cb.
