BNM has already clearly stated that this only apply to cash transactions where we are trying to get rid of 1 cent coins. But it is obvious that even if you are paying with credit card, check and online transfer, most of the retailers will still round the 5 cents up.
When you go to bank and make a payment of $9.98 over the counter. You may write down $9.98 in the bank in slip. Upon making payment, the cashier will have to get $10.00 from you. Which is fine since now the rule is to round it up. When the transaction is done and you get back your proof of payment, what do you think your paper work will say you paid ? Correct, $9.98 !
So be smart, round it up and write down $10.00 because that is the actual amount you pay.
What if the amount is $9.96, you would definitely have to pay $9.95 but should you write on the slip $9.95 or $9.96 ?
If you did write down $9.95 as in honestly you have just paid that exact amount and not 1 cent extra, you may face the risk of another funny finance scenario ... credit card forward interest calculation where your 1 cent ignorance could have cost you $15 !! Well, not that funny but its happening everyday ...
Guess what, with this GST coming soon ... we consumers may not see it how it comes at all, we may NOT even realize after many years ... but all these little things combined together are THE ONES that kill your personal finance, especially if you don't know.
Government and the big boys can do all kind of tricks to keep the national inflation number down but what really matter is your own REAL personal inflation rate!
