# Thread: How to calculate dry cabinet monthly electrical bill?

1. ## How to calculate dry cabinet monthly electrical bill?

Need to prepare the answer to this question which my "home minister" is likely to ask.

For instance, the Digi-Cabi AD-060 has the following specs:

Effective Capacity: 60L
External Dimension: W35 x D31 x H55cm
Power Consumpiton: 5W
Door: 1
Shelf: 2

Singaporepower.com.sg charges 16.73c per kWh. so the monthly electrical cost is...??

Sounds like a maths test paper...

2. Since it's 5W, 1KW would be 1000W.

16.73c / H

5w = 5/1000 x 16.73 = 0.08365

Assuming it runs non-stop (which shouldn't be the case), 24 hours = \$2.0076

In which a month of avg 30 days = \$60.228 ~= \$60.23

Did I calculate wrongly?

3. hehehe....

so it should be 5w x 24 hrs x 28 days (take average) den multiply by (16.73 divided by 1000) den should be about 56 bucks...

something to note here is that, the electric dry cabinet have a electric heater that have a control unit inside, so it should not be always on. Unless you have set to full power manual, den your per month cost would be this much... otherwise not much really...

4. Yep, the dehumidifier should stop when the humidity is reached and active if it's not. So it shouldn't be going on 24/7

I think you went wrong here.

5w = 5/1000 x 16.73 = 0.08365 <---- this unit is in cents / hour, not \$ / hour.

6. oooops... den i also sala liao...

7. Yeah, no wonder I was wondering how can a dry cabinet cost more power than my PC (350W) running 24/7. Thanks dude.

5w = 5/1000 x 16.73 = 0.08365c

8. Mr espn ah, something wrong leh.
My ceiling light is 100W x3, and they are on for at least 8 hours per day.
My refrigerator is 1000W, and they are on the whole day.
I must be paying a few thousand \$ elec bill already?

Never doubt the words of espn

10. so it should be 5w x 24 hrs x 28 days (take average) den multiply by (16.73 divided by 1000) den should be about 56.2128 cents? kaoz... its like saying... did i drop a 50 cents coin? aiya forget it... din know electricity so cheap... maybe its becos its only 5w, while normally we see bills in hundreds & wonder how come we use so much...

/me start to blame the PC...

11. Ok, tell the home/finance minister this:
In any home, this is the typical home appliance electrical cost, from big to small:
1. refrigerator 1000W
2. water boiler (1000W or 2000W)
3. ceiling lights (200/300W)
4. television (a few hundred W)
5. fish tank
6. rice cooker
7. washing machine
8.
9.
.
.
.
.
.
100. your dry cabinet (only 5W)

12. so \$1 per month got spare change come back? got hope, got hope! my proposal may go through the finance committee!

Aiya, the trick is, to explain every other things that consumes more electricity than the dry cabinet, and not to mention things that consumes less electricity lah. (Marketing lesson 001)

First you buy her a diamond ring, at least 1 carat.

After that you want to buy a 100L or 160L 5w, 10w cabinet she also won't mind.
