ah siao, if I earn 5 figures, then 10% wld be fine la! Keke.. 3 mths wld be a lot liao.. I agree that for most pple, 30%-50% is good provided they have factored in all the usual expenditures. Else, not quite possible. Like my hb, most of his pay goes to car loan, parking, insurance, utilities, parents' allowance and study loan. Not much savings except for annual bonuses/aws.
