I agree is specific to person personal usage.
However, I disagree on your calculation. You're comparing having 10% cashback to not having anything (hence RM500). I'm comparing having 10% cashback to having 2.5% (since your amex is maxed out) cashback, so your effective gain is 7.5%, as mentioned in my last line.
Put another way:-
Situation one - you only have AMEX and cashback maxed out so we only consider 2.5% - this one we consider as 'normal'
Situation two - you have AMEX and cashback maxed out, so you get HLB for 10%. You gain 7.5% (because if you did not take HLB, you would still have gotten the 2.5%). Hence your amount necessary to be spent is RM667 to cover the RM50 (which you would not have needed to pay without HLB).
Your statement from top to bottom makes no sense.
"You're comparing having 10% cashback to not having anything (hence RM500)."No, I am comparing 10% vs 7.5% as it should be. Where to get the result for RM50 cashback is RM500 vs RM667.
"I'm comparing having 10% cashback to having 2.5% (since your amex is maxed out) cashback, so your effective gain is 7.5%, as mentioned in my last line.""Effective gain"? I think you need to define to me what you mean by "effective gain", because as far as i know effective gain means after you minus all the cost, your final amount is known as effective gain. BUT there is no such thing as "effective gain" when comparing two product. This is not call effective gain.
If 10%-7.5% (as in your first calculation) = 2.5% is what you call effective gain. Explain to me then, this is 2.5% of what?? How do you calculate in monetary form this 2.5% gain?
"Situation one - you only have AMEX and cashback maxed out so we only consider 2.5% - this one we consider as 'normal'"No, this is call weekday spending on Amex
"Situation two - you have AMEX and cashback maxed out, so you get HLB for 10%. You gain 7.5% (because if you did not take HLB, you would still have gotten the 2.5%). Hence your amount necessary to be spent is RM667 to cover the RM50."Again, what?? 10-2.5=7.5% gain.... So i need to spend 667 to cover rm50??
"(which you would not have needed to pay without HLB)"????
