Is that in the UK or Philippines?
Put it this way, for a family of four, excluding rent but including everything else, which figure woud be sufficient per month for a reasonable standard of living
P20,000
P30,000
P40,000
P50,000
P60,000
P70,000
P80,000
P100,000
I have read that the minimum would be P40k, and any more would make life increasingly comfortable.
