Increase in Electricity rate

UPDATE: Click HERE to download the file for easy calculations.

Household electricity consumption

I have covered the topic on how to measure your household electricity bill in my last article in May 2008. Since then, SP services never fail to increase electricity tariff for four consecutive quarters. Starting in April, our new rate will be 23.56 cents/kWh or an average increase of $2.47 in our monthly electricity bill in four-room HDB flats as reported by Straits Times. The latest reason cited is the increase in oil price over the past three months from US$99.38 to S$102.95 per barrel.

Ranking of power hungry household appliances

The best power saving method is NOT to switch on anything. We know it is impossible so how can you maintain or reduce your electricity bill? Identifying the most power hungry appliances and reduce its consumption is the best approach. Below is the typical list:

Ranking	Household Appliance	Power Consumption (W)
1	Bathroom Heater	2000
2	Induction Cooker	1200
3	Cloth Iron	1000
4	Water Boiler	750
5	Air Conditioner	600
6	Rice Cooker	500
7	Fridge	200
8	Desktop PC	160
9	CRT TV	135
10	Fan	60
11	Notebook	55
12	Light bulb	40

 
As a rule of thumb, appliances that heat up or cool down in the shortest time consume the most power. Bathroom heater tops the list with 2000W of power consumption while light bulb only consumes 40W. Appliances worthy of mention are Induction Cooker, Cloth Iron, Water boiler and Air Conditioner which are power hungry. To get a realistic feel of how much they are consumed, we need to know the hours of usage to get the monthly bill.

Household Appliance	Power Consumption/ unit (W)	Hours of usage/ day(Hrs)	Monthly Bill with GST (S$)	Ranking
Bathroom Heater	2000	1	15.13	3
Induction Cooker	1200	1	9.08	6
Cloth Iron	1000	0.5	3.78	8
Water Boiler	750	0.5	2.84	10
Air Conditioner	600	8	36.30	1
Rice Cooker	500	0.5	1.89	11
Fridge	200	24	36.30	1
Desktop PC	160	8	9.68	4
CRT TV	135	9	9.19	5
2 Fan	60	4	3.63	9
Notebook	55	4	1.66	12
3 Light Bulbs	40	5	4.54	7
Total Electricity Bill			134.01

 
After punching in the average consumption per day, we get a realistic power consumption of the appliances. Fridge and Air-Conditioner top the bill charges while notebook tails behind. To effectively cut down on the bill, we explore how to reduce the usage time of the appliances. Bear in mind that basic necessities such as fridge cannot be touched. Below are some suggestions:

1. Use fans instead of air conditioner;
2. Cut down on using Induction Cooker and use gas instead;
3. Reduce the frequency of using bathroom heater;
4. Iron cloth every fortnight. FYI, heating up the iron is very time consuming;
5. Refrain from using water boiler to keep warm and use vacuum flask instead;
6. Adopt standby or hibernation mode for breaks exceeding one hour; and
7. Sleep early so watch less TV programs.

Household Appliance	Power Consumption/ unit (W)	Hours of usage/ day(Hrs)	Monthly Bill with GST (S$)	Ranking
Bathroom Heater	2000	1	15.13	2
Induction Cooker	1200	0.25	2.27	8
Cloth Iron	1000	0.05	0.38	12
Water Boiler	750	0.25	1.42	11
Air Conditioner	600	3	13.61	3
Rice Cooker	500	0.5	1.89	9
Fridge	200	24	36.30	1
Desktop PC	160	6	7.26	5
CRT TV	135	6	6.13	6
2 Fans	60	12	10.89	4
Notebook	55	4	1.66	10
3 Light Bulbs	40	5	4.54	7
Total Electricity Bill			101.47

 
After changing the consumption pattern, only fans cost more due to longer period of usage. If the fridge is your top list, then you have near to your target. Revised bill is $101.47 which is a 24.28% reduction in power consumption.

Conclusions

There are some devices (S$150) sold in the market which promise to save your electricity bill. The basic operation is to optimize the inductive and capacitive powers (correcting the power factor) which exist in any power supply due to different appliances used. This is especially useful for Air conditioner, washing machine and other inductive devices. In Singapore, the effect is noticeable for 5-room flat or bigger units but less significant in smaller HDB units. Suppliers claim that the savings vary between 5-25%. If you are interested, please attend computer show as they are always participating in such shows. Watch out for mini-sun or power save booths.
Now, you can save your pocket money and environment at the same time and preserve a greener earth for our future generations. I must talk big because cutting back on what you are currently enjoying is painful. Trust me…

MediShield Upgrade Comparison

Ward Selection for MediShield

UPDATE (31 Jan 2014): I have been very busy recently due to work commitment. Surprisingly, this file has more than 7,000 over download. I hope to update this in view of the recent talk about the pioneer package. Stay tuned.... and thanks again for your support.


UPDATE (18 Jul 2011): Thanks for your support. Near to 700 have downloaded and use this excel file to better their health plan. I welcome any constructive suggestions to better this file for future reference.

After posting the excel file (version 11), let's see what MediShield covers.
We shall compare the following scenarios below. You can punch in the data in the excel file to derive the same results.

Scenario	1	2	3	4	5
Room and Board (R&B)	24,200	24,200	24,200	24200	5,200
ICU	1,800	1,800	1,800	1800	0
Day Surgery	728	728	728	728	0
Implant	0	0	0	0	0
Days in R&B	52	52	52	52	5
Days in ICU	2	2	2	2	0
Total Hospital Bill	26728	26728	26728	6300	5200
Ward Chosen	C	B2	B1	A	B2
Age	50	50	50	50	50
Insurance pays	21885.2 or 81.88%	21735.2 or 81.32%	8336 or 31.19%	6914 or 25.87%	600 or 11.54%
You pays	4842.8	4992.8	18392	19814	4600

If you have only MediShield, staying in Ward B2 or C has its merits. This is an ideal case to show CPF MediShield can pays for 80% as intended.
Choosing Ward B1 or A will dramatically blow up your medical expenses as illustrated in scenario 3 and 4 respectively.
But wait a minute, how many of us spend 52 days in hospital?
A more realistic case is Scenario 5 whereby minor accident happens to us. Your feet swells without your permission and you stay only 5 days in hospital and the bill is only S$5,200 with no surgical operations. Now, you will be paying S$4,600 or 89% of the bill under MediShield. If luck is not on your side and you visit a hospital every 5 years, your MediSave savings will be easily depleted before you reach 80. When this happens, many suddenly realized that MediShield is insufficient and need a private plan to fill in the gap. Since private insurance excludes previous medical conditions, you will not be paid for heart related conditions if you have heart problem before you buy the private policy. Therefore it is imperative to buy the insurance before you develop any illnesses since most are guaranteed for renewal without questions. This is especially true because MediShield expects you to die before 86 as you have ZERO coverage when you are 86. Else, it ensures you die poor if you live beyond 86 because you will pay 100% of the medical bills.

An Ideal Private Insurance Plan

From my earlier blog, statistics showed that private insurance companies pay S$22 out of S$100 premium collected while CPF MediShield pays S$53 out of S$100. Claiming insurance may be one of the factors as there are many limitations and constraints especially the micro clauses in the contract dealing with historical medical conditions. But since MediShield has its weaknesses, you would like to maximize your money on a policy that pays the most and covers better than MediShield.
For full coverage (ie. zero payment), the premiums are expensive especially when you grow older. We have to access if we are able to afford the premium because it costs only $42/year when you are young but $7000/year if you are old. Without income after retirement, can you afford to pay the premium at old age? Many jump into buying policies that benefit them in the short term and forget that the premiums are much higher when they are old.
So the criteria for private Insurance are:

1. It should be better than MediShield;
2. It should pay most of the medical bills;
3. In case of hospitalization, the insurance payout should be substantially higher against the premiums paid over the years (remember ROI?); and
4. The policy should be affordable till old age.

Case 1 – Long Stay in hospital

Using the same scenario as above, MediShield (Ward C) shall be the benchmark.

Scenario	CPF MediShield	GE SupremeShield B Plus	GE SupremeShield B Plus
Room and Board (R&B)	24,200	24,200	24,200
ICU	1,800	1,800	1,800
Day Surgery	728	728	728
Implant	0	0	0
Days in R&B	52	52	52
Days in ICU	2	2	2
Total Hospital Bill	26728	26728	26728
Ward Chosen	C	C	B1
Age	50	50	50
Deductible	1000	1000	2000
Co-Insurance	3042.8	2572.8	2472.8
Insurance pays	21885.2 or 81.88%	23155.2 or 86.63%	22255.2 or 83.27%
You pays	4842.8	3572.8	4472.8
Years policy is valid	10	10	10
Claims/Premiums	18.33	9.82	9.44

With Great Eastern Supreme Shield B Plus, it covers more for the same Ward C plan. Even if you upgrade to Ward B1, the medical bill foot by you is still lower than CPF MediShield.
If the policy is enforced for the last 10 years (or you have paid 10 years of premiums), the Claims/Premiums ratio will reveal the value of this policy. With lower premium and less coverage, MediShield has a score of 18.33. It implies that the medical claim covers the insurance premiums for the last 18.33 years. For GE Supreme Shield B Plus, both are near to 10 so it implies GE earns little from you.
We conclude that private insurance has its merits for long term hospital stay as it provides better coverage than MediShield. However, we need to compare the various plans to suit personal needs. You can now do so with the excel file.

Case 2 – Short stay in hospital

As illustrated above, MediShield is weak in pure R&B charges. Let's see how private insurances fare.

Scenario	CPF MediShield	AIA HealthShield Gold Elite	Aviva MyShield Plan 3
Room and Board (R&B)	5,200	5,200	5,200
ICU	0	0	0
Day Surgery	0	0	0
Implant	0	0	0
Days in R&B	5	5	5
Days in ICU	0	0	0
Total Hospital Bill	5200	5200	5200
Ward Chosen	B2	B2	B2
Age	50	50	50
Deductible	1500	1500	1500
Co-Insurance	150	370	370
Insurance pays	600 or 11.54%	3330 or 64.04%	3330 or 64.04%
You pays	4600	1870	1870
Years policy is valid	10	10	10
Claims/Premiums	0.5	0.75	1.53

Both AIA HealthShield Gold Elite and Aviva MyShield Plan 3 offer to pay 64.04% of the bill compared to MediShield's 11.54%. Now, with the Claims/Premium ratio, ceteris paribus, we see that Aviva MyShield Plan 3 is better than AIA HealthShield Gold Elite due to lower premiums.

Case 3 – Typical Surgical mid-term stay

Let's consider a case study of a mid-term stay with coronary artery bypass graft surgery (Example from Prudential website).

Scenario	CPF MediShield	Prudential PRUshield A+	NTUC Enhanced IncomeShield Basic + ASSIST rider
Room and Board (R&B)	5870	5870	5870
ICU	1630	1630	1630
Day Surgery	9000	9000	9000
Implant	2400	2400	2400
Days in R&B	7	7	7
Days in ICU	2	2	2
Total Hospital Bill	18900	18900	18900
Ward Chosen	B2	B2	B2
Age	52	52	52
Deductible	1500	1500	1500
Co-Insurance	369.75	1740	1690
Insurance pays	5726 or 30.3%	15660 or 82.86%	17010 or 90%
You pays	13174	3240	1890
Years policy is valid	10	10	10
Claims/Premiums	10.86	4.56	4.17

Private insurances always place their example to their advantage. In this example, MediShield's weakness is exposed as you have to pay 70% of the medical bill. Though the Claims/Premiums ratio is high, forking out $13,174 may wipe out most of your MediSave account. Comparing with Prudential PRUshield A+ and NTUC Enhanced IncomeShield Basic + Assist Rider, both private plans cover most of the costs with the NTUC paying the most out of the 3 plans. However, its premium is also higher as compared with PRUshield.

Benchmarks

To compare policies, benchmarks are introduced. Below are the descriptions:

1. Percentage of bill paid by insurance measures the amount of medical bill paid by the insurance company over the total medical bills. (Higher is better)
2. Claims/Premium paid measures the insurance payout over the premium you paid over the years. (Higher is better)
3. Future Premiums (to be paid till your death) considers your ability to service your premium till you die. (Lower is better)

These factors are given a certain weight to produce the ranking for your consideration.
I hope the excel file will help you get the best plan for your needs.
