I saw some discussion on salary and cost of living in Singapore.
On salary part, please don't use or ask people whether it is 1:1 or whatever. This is very bias comparison. Not everyone are paid the same in Msia, especially different locations where some have come from KL, Penang, Melaka and JB. U can definitely use 1:1 for your own comparison to gauge your risk and financial planning.
Same uni, same field, same specialization, same years of working experience doesn't mean each individual are getting paid about the same. Considering nature of biz, size of company, line manager/management and location (KL, Penang or JB) make huge different to individual's salary.
One Accountant in KL that earns RM8k doesn't mean every Accountant with same profile earn RM8k, and different locations with lower cost of living contributed to lower salary compared to KL.
U can earn RM8k in KL and offered SGD9k and telling people that u get salary increases even coming to SG. Maybe someone at your peers level or same profile as u are already earning RM10k and come to SG being offered SGD9k.
So please use salary benchmark to compare or use available market data to make comparison, Glassdoor is one of source u can go to. If u are too lazy to do your homework, then u should consider to stay put until u have the motivation to do your homework to come SG for work.
Cost of living in SG is definitely higher than KL/MY (This is assuming that u plan to settle down in SG, buy house, have kids and so on)
If u plan to live in JB or short term in SG then cost of living is not an issue for u. Work hard, save hard and go back.
Why I said SG is more expensive,
1) House (U can argue it is same price in KL or JB, but do u get same salary paid in SG?) U can buy new private unit condo 1000sqft in KL with RM650k, but can u buy private condo in SG with SGD650k?
2) Transport (If u are single, sure no problem. If u are married with small kids, then without car can be really troublesome) Kids need to go to school, emergency to clinic/hospital, grocers for family etc.
3) Insurance and medical (self-explanatory)
But if u plan to stay JB and work in SG for few years then go back to Malaysia, why do u want to make comparison? U already making 3 times more then your peers/friends in Malaysia (Assuming u get same salary in SG, and when the time u go back FX is still the same lol).
On the housing part, majority of Singaporean lives in hdb, so why is the comparison done with private condo? If you bought a hdb, you can service your monthly installment with cpf and possibly no cash out of your pocket, if you earn enough.
