After retire... how often do you use car??? You have to go here and there everyday??? The purpose is only to get you to nearby grocery and restaurant...

Electricity and water bill how much?? RM200+ should be able to cover right???

Medical bill... go public hospital??

Breakdown every month ke??? don't know DIY???
I didn't say RM600k is going to be super luxury for you to retire but you can at least ensure you have decent meal with enough money for household goods and some entertainment...
I shit you not... my ex-colleague with his wife mia average expenditure after retire is just RM1.5k.... before retire was a Head position in MNC financial firm....
His life was simple... breakfast just milo or nestum with biscuit..... Mixed rice for lunch RM7+ while wife makan roti or sometime noodles... varies from RM3 to RM8.... night cook simple meal... vege/egg/meat.... cost also likely less than RM20....

Daily do gardening... clean house... go meet up at the park with neighbours....

No more than RM30k per year for husband and wife... including other cost such as insurance etc...
Seriously... when you are old... you aren't going to spend like you are in your 30's.... but if you still want to eat good... dress good... have the best entertainment... obviously you would say RM600k is not enough for retirement but reality is... a lot and I'm not saying this based on gut feeling but literally EPF stats..... living with much less than RM600k and they also ok jer....
