Reasonable salary to accept in KL (Kuala Lumpur)

Good day!

I am happy to find this site to help me decide on the offer I received. I will be leaving my 4 kids here in the Phippines to work in KL for an O&G industry. The initial base salary offered was RM Protected content of base salary and allowance) I converted it to peso and its a bit higher to what I am currently earning. However, I should obviously send bucks to my kids every month and at the same time cover my expenses in KL. I did counteroffer though and waiting for the result.

Can anyone suggest how much should I counter to accept the offer?

Appreciate your responses here.
