Degree fresh grad, earning 2.6k here

House rent = RM180 share with friends, no need to pay electricity and water since the bill is always low.
Petrol = RM150 Dont have car, rempit.
Meals = RM400 A lil bit expensive since I'm working at KLIA, screw you Ali Maju.
PTPN = RM100
Parents = RM 300
Basic Necessities = RM100 (Topap, internet bill share with friends)
Some entertainment = RM100

RM2600 - RM1330 = RM1270

With that kind of balance I managed to grab the bike Im using right now on cash after working for 5 month for RM7.5k. Malas nak utang.

So in my opinion its more than enough to survive, heck I think its enough to live a comfortable life with RM2.5k. Depends on your definition of comfortable though.
