Here is a breakdown of the cost of living in Kuala Lumpur. If you are considering teaching here, use this as a guide to decide if your school is giving you a fair deal. Malaysia's currency is called the Ringgit. I call it the Blinggit. 100 Ringgits equals about $30 CDN. For most things, I'd say a ringgit buys you about the same as a dollar. The three exceptions are cars, houses, and beer.
Income tax
For any teacher it shouldn't go above 10%. 10% would be for the top of the pay scale at an international school.
Accommodation
Unfurnished basic (ghetto) apartment: RM 500-600
Master bedroom fully furnished: RM 250-300
Nice condo in nice area: RM 2,000-2,500
Two story townhouse (older): RM 800-1,000
Newer style townhouse: Over RM 1,000. Depends how nice and what area.
Taxi
Basic fare starts are RM 2, but you'll never get the meter rate.
Train
I enjoy taking trains. I took the train from KL to Butterworth, which is where you catch the ferry for Penang. I believe the ticket cost me about RM 40, which is pretty damn cheap for an 8 hour train ride. I had my own bed and slept the whole way.
Bus
I recently to the bus from KL to Lemut, which is where you catch the ferry for Pangkor Island. The bus tickt was RM 19 for four hours. Not too bad.
Food
Lunch or dinner at a Chinese or India restaurant (nothing fancy): RM 6-7
Beer
Big Bottle: RM 12-15 depending on the brand.
Can: RM 6-7
Mug: RM 9-10
Jug: RM 50 (can be cheaper during hh)
