Game of SMRT

Have you heard of some whizkids that are able to fly for free in the US? They do so by taking advantage of the frequent flyer schemes and some flaws in the pricing system of flights. Based on this I started wondering if we could also game the local MRT system and ride for free? Well, no such luck here! But using the various incentives out there, we can reduce our MRT fares considerably. Let's see how this can be done!

 I will use myself as a case example. Every Mon-Fri, I travel from the East where I stay, to the West where I work. Each of these trips cost me $1.88, so per day its $3.76. Assuming 20 working days in a month, that will be $75.20. Assuming I spend around $4 on weekends, and 4 weekends in a month, the total bill for public transport works out to be  $107.50 per month. Woah, that's a lot of money!!

Now, let's look at ways to reduce this amount.

POSB Everyday Card
 Do you know that POSB Everyday Card offers 100% cashback on your MRT and bus rides every Friday? Utilizing this scheme, I can reduce my MRT fares on Fridays to $0. So the new monthly transport fare will be 107.5 - 4*3.76 = 92.46. Good? This is a 14% reduction already! Let's continue.

Free Early Morning MRT Rides
Do you know by exiting before 7.45 am on weekdays at any of the 18 designated MRT stations in the city area, your ride will be free? I stay in the east and work in the west, so this means I can travel from the East every morning, exit at Tanjong Pagar MRT station, and re-enter and continue on my journey to the West. In doing so, my morning train fare is cut from $1.88 to $1.32, or a reduction of $0.56 everyday. So the new monthly transport fare will be 92.46 - 20*0.56 = 81.26, which is a 24.4% reduction in total. Let's continue.

Travel Smart Scheme
I have joined the Travel Smart scheme for a few years already. I am a platinum member meaning I earn more points for every km I travel. On average I earn around $8 in rebates every month. So the new monthly transport fare will be 81.26 - 8 = 73.26.

OCBC Frank Card
Using this card, you will get rebates of 6% if you spend >500 a month using this card, and if you use Flashpay auto top-up. Well, for me I don't spend so much on this card but I still get rebates of 0.5%. So the new monthly transport fare will be 73.26 - 0.5%*81.26 =  72.85.

Thats about it. We have reduced the fare from 107.5 to 72.85 which is a 32.2% reduction in monthly transport fare!

There are other techniques like taking advantage of a full refund when the MRT breaks down, but such chances are not frequent so I don't bother about them for now.

Retirement 2

In my last post, I wrote that there are two schools of thought to retirement:

  • 'Extreme savings' : You scrimp and save so that you can retire early
  • 'Work to enjoy life' : You continue working and have a late retirement to enjoy a comfortable lifestyle
 After thinking about it, perhaps there is a third school of though to reconcile both and have the best of both worlds. That is, the 'financial freedom' school of thought:

  • 'Financial freedom' : You work to achieve financial freedom. This means you have earned enough to maintain your current lifestyle, and you are able to quit if and when you want to. You don't necessarily have to retire from work, but the point is you are no longer working for the money.
I think this is what I should aim for! Financial freedom!

So now, a quick analysis on how far I am from financial freedom:

Monthly expenditures (this includes everything from groceries to monthly mortgage to child education expenses and insurance policies) = $4100

Monthly passive income (from stocks, bonds, savings deposits, fixed deposits etc.) = $391

Hmm...well...seems I have some way to go...

Retirement

I had an interesting conversation with my wife last night. I told her that I will like to retire early, and accomplish this by extreme savings ie. eating out less, buy cheap stuff, cut back on holidays etc. However, my wife disagreed with me and said she will rather work longer so that she can enjoy life ie. eating expensive food if she feels like it, maintaining present lifestyle and so on. It seems these are two different schools of thought.

The 'extreme savings' school of thought partly came from the articles I read on Marketwatch, one example is:

http://www.marketwatch.com/story/how-to-retire-early-35-years-early-2014-01-17

From the article:
"One secret to their success? They live on very little for a family of three: about $25,000 a year. They own a car, but mostly bike. Dining out is an occasional luxury. And shopping for stuff? That’s best avoided. But their philosophy goes beyond mere scrimping, says Mr. Money Mustache. It’s about enjoying life with less."

But after listening to my wife and her arguments I'm no longer sure which school of thought I belong to...hmm....

Cost savings of using LED lights

LED lights are more expensive than fluorescent lights, but are there any cost savings in the long run? How many years it takes before we spend less using LED than using fluorescent? Let's do a spreadsheet analysis to find out!

Assumptions:
Cost of LED light 24.6 W = $35
Cost of fluorescent light 32 W = $6.80 (Sheng Shiong)
Electricity tariff = 0.2233 per kWh
Days in a month = 31
Hours light is switched on per day = 6
Both the LED and fluorescent light does not spoil in the time period we are analyzing.

So there you have it! In the spreadsheet below, we showed that the initial cost of using LED is higher than fluorescent. However, after 92 months (7.7 years), the total cost of using LED will be less than the total cost of using fluorescent.

This is analysis of using LED purely from an economic standpoint, and it is up to you to decide whether LED lights make sense for you or not :)

Hello World!


I started this blog to raise awareness of simple ways you can do to save money and result in larger cash flows for investments/savings/enjoyment etc. As to the name, 'opti' is short for 'optimization' and as its name suggests, we aim to optimize our personal finances. Stay tuned for our articles!
