Hmm .. you too laugh at precision two decimal points investment return?
Bank loan interests for Dec 21 still maintained at 1.04929%. Five decimal points!
Yeap. When banks collect those five decimal points loan interests from massive customers. It will add up to big round down number!
Same same for precision two decimal points investment returns! Over two to three decades of two decimal points. It can also add to mid or high single digit! :-)

Well, Uncle8888, you got something in common with buy-and-forget index fund investors lol!
ReplyDeleteThey also very interested in 2 or 3 decimal points ... 0.01% difference in expense ratio is A LOT for them 😂
We are not uncommon! :-)
DeleteSpur,
DeleteLOL!
Shhh.... I won't say anything.
CW,
ReplyDeleteMost banks only use decimal up to 2 places. DBS is one that I know use up "precision" up to 3 decimal places for home loans, and that's already quite "malu"...
Come, tell us the bank that uses "precision" up till FIVE decimal places so I can have a laugh too!
You know what? From a landowner perspective, wouldn't I earn more when I can round up the bank loan interest up and charge my customers 1.05%?
So its the REVERSED.
That bank that uses 5 decimal places is giving margin away due to competitive pressures...
If I'm an investor, I would rather invest in the bank that have pricing power to charge 1.05% in 2 decimal places over the one that charges 1.04929% ;)
You think why Apple so powerful and cash rich?
Have you seen Apple price its products with precision up to 2 decimal places?
That 2 decimal places trick is often used by supermarkets - instead of selling $2 dollars, sell $1.95 ;)
Evidently there are customers who are "turned-on" with a savings of 5 cents!!!
As for investment returns, if we have to add two decimal places returns over decades to come to ONE extra percentage... We are either "try-hard" or very "calculative"...
I would think for most people, if its investment returns over DECADES, the first thing we'll ask is how many multiples or baggers will our portfolios become?
LOL!
LoL!
DeleteNot correct that only DBS uses "5 decimal places interest rate" for their loans. SIBOR/SOR are in 5 decimal places, hence, all banks that peg their floating rate loans (home & others) to SIBOR/SOR also technically use 5 decimal places, i.e., 1 month SIBOR + spread (say 0.75%). Appears there is a slight improvement for the future SORA (in 4 decimal places?). Of course, for fixed rate loans, banks normally stop at 2 decimal places.
ReplyDeleteForex trades are even more "precise", up to 6 decimal places are used! For sizeable quantum, the no. of decimal places does matter
SMOL got chance to laugh louder at Forex trades. LOL!
DeleteCW and retiree5559,
DeleteStop. You guys are too funny!
Investor A's investment return is 1.049%. Investor B flexes by saying his return is 1.04929% for the win!
Then Saver C blur blur comes along with his 4% CPF interest returns... Investor A and B looked at each other red-faced.
We are still talking about investment returns right?
How did the conversation went all the way to forex???
Distract and switch subject?
LOL!
1) CW,
I know you and I can joke. So no harm no foul here ;)
For forex, if you exchange in hundreds of million Sing dollars, of course its in our interest to use 6 decimal places ;)
If just change a few hundred Sing dollars to visit JB, you try at the Money Changer lor! See if the Money Changer would laugh his head off if you try using 6 decimal places!
2) retire5559,
Not sure whether you can joke, but here's my "Trust but Verify" poke:
DBS SORA ratese
Like I've said, 3 decimal places is already quite "malu" ;)
Of course in practice its 5 decimal places. But why only show 3 decimal places on website then?
Gee... I wonder why for fixed rate loans, banks just stop at 2 decimal places?
I just know one thing. Let's hope CPF sticks with 1 decimal place. I don't think its to our advantage if one day big daddy decides to use 2 decimal places for our CPF interest rates!
Well, the bigger the principal amount the bigger the scaling effect of the formula.
ReplyDeleteI usually goes for 4 decimal points for my own formula in counting my returns. Every penny counts!!!! LOL.
Wah! Steady!
DeleteWith headline inflation at >3%, I think people more interested in the numbers to the LEFT of the decimal point for their salary increment, bonuses & investment returns! 🤣
ReplyDeleteEven if counting cents, round to 2 decimal places can liao.
Reminds me of my grandpa's stash of old coins ... 1940s 1/2 cent Straits Settlements & British Borneo coins, and 1930s 1/2 penny British coins ... and get this British FARThing coins 😂 No, they're not smelly ... a farthing is 1/4 penny.
I guess those days money was pretty big lol.
PS: In the olden pre-decimal days, 1 pound = 240 pennies & 1 shilling = 12 pennies. 1 pound could pay for a family's weekly groceries.
