Does anybody know a website/specific page listing a break-down of expenses in Singapore?

It has been hard to find a decent practical list -- UStravelstate site lists $126 to $145 per day. I doubt my company is going to give me that per-diem rate.

I will get accomodation provided and my boss asked me to figuring out the living costs there.

I need some guidance, since I will be for 2 or 3 months working in a project.

Thanks for your kind response
