Living Expense in Kuala Lumpur - 2014

I guess my answer would be a bit late... I post it anyway as it could help others
Do you know which area you are planning to live? Where your office will be? These are the 2 most important questions and it can change your cost of living drastically.
Public transport are simply a nightmare in KL so you should consider buying a second hand car unless you live downtown. My office is a 10mins ride by car or 1hr15 with public transports! It gives you an idea of public transport efficiency in KL! Bus time tables are simply never respected and when it rains you have no taxis and buses have serious delays due to traffic jams...
For a one bedroom apartment depending on where you want to live it will be between 1.2k to 3.5k.
For a local kindergarten, you have to budget 1,200RM/month without school bus. School bus depending on distance from school is 200 or 300RM per month + meals if required (7-10RM per day).
Electricity/Cable TV/Internet/Mobile phones are rather expensive if compared with Europe or Australia. 600RM total.
Note: For a foreigner, you will have to give a deposit of 1,500RM to get a phone line in Malaysia! For a local, it is 70RM. Same for mobile phone. Same for school and landlords ask usually for a 3 months advance rent. So prepare a big envelop for all various deposits.
Food was once upon a time cheap in KL but I find it is now closer to Singapore prices (still cheaper 20-30%).
Also depending on your standards:
Meat from australia : 25RM a steak / Fresh milk australia 9RM/bottle. Veggies are quite cheap if local (papaya 5RM, pineapple 6RM, local broccoli 8/9RM per head). Imported chicken free range, guaranteed no antibiotics 23RM. A local chicken will cost 10RM.
Finding good fish in KL is nearly impossible. Imported salmon is available (defrost) at an average price of 23-28RM per slice!! Shrimps are not cheap either. Local shrimps are avail from 9RM/100gr.
You have to know though that local vegetables are grown in the Cameron Highlands. A recent official study found that all vegetables and salads coming from this area contain traces of 3 different types of insecticide... Knowing that, I now only buy imported vegetables (not from China either!), which means more expensive
Dinner is still cheap though. For a meal at a local hawker center you will eat for 10RM or less. Sushi dinner will cost you 30RM/person. Dim sum dinner like Din Tai Fung is around 40RM/person. You also have of course more expensive dining like mediterranean  (way over 100RM/person).
A cinema ticket costs 10RM.
Taxes are depending on your salary (30% for the highest bracket).
