A question for the more experienced, how do the points calculate on the signature?
1. Total spend for the month (less ineligible transactions) * 1.5
2. 1.5 * the dollar value of each eligible transaction (less cents)
3. Other method
Depending on the number of transactions there could be points "missing" under method 2. I'm still to use my card so haven't tested it yet.
Thanks in advance.
It's method 2, plus some additional rounding
Like deka & cfellows I've been keeping track of my points regularly by spreadsheet also (namely to see if they issue points for certain transactions).
I've determined that citi will round down each transaction to the nearest dollar, then award points based on that. They will then sum up all points earned and round the final amount.
E.g.
Code:
[TABLE="width: 200"]
[TR]
[TD]Spend[/TD]
[TD]Points Earned[/TD]
[/TR]
[TR]
[TD] $ 1.00[/TD]
[TD="align: right"]1.5[/TD]
[/TR]
[TR]
[TD] $ 2.00[/TD]
[TD="align: right"]3[/TD]
[/TR]
[TR]
[TD] $ 3.06[/TD]
[TD="align: right"]4.5[/TD]
[/TR]
[TR]
[TD] $ 0.50[/TD]
[TD="align: right"]0[/TD]
[/TR]
[TR]
[TD] $ 11.85[/TD]
[TD="align: right"]16.5[/TD]
[/TR]
[TR]
[TD] $ 2.99[/TD]
[TD="align: right"]3[/TD]
[/TR]
[TR]
[TD][/TD]
[TD][/TD]
[/TR]
[TR]
[TD]Total[/TD]
[TD="align: right"]28.5[/TD]
[/TR]
[TR]
[TD]Final[/TD]
[TD="align: right"]28[/TD]
[/TR]
[/TABLE]
I've been applying this method and, like deka, have found it reasonably accurate. The bit that gets my goat is the 99c/1.99/2.99 etc type transactions where i feel ripped off. I estimate i lose out about 100 points a month due to this rounding.
So far i've found that they've awarded points for utilities and insurance, i don't have any ATO bills to pay unfortunately (fortunately?).
They always seem out a handful of points by the end of the month however, which i can't explain. It's almost like they take the final number throw a dart and add/subtract that number from the total.
edit: It's possible that citi sum up the points each day and round based on that (rather than monthly) and not all transactions will get processed and appear on the same day (despite whether or not they're transacted on the same time)
