For those who are thinking of retiring, here are some useful info

Food $400
Utility and phone bills $300
Public transport $200
Entertainment $300
Total $1200

For a retired couple $2400 pm or $28.8k pa

So, if your home is paid up and you no longer have any dependents, you can already retire if your passive income is $30k pa.

You just need to invest in assets which give you $30k pa in dividends. So if you have $600k worth of assets which yield 5% pa of dividends, you will get $30k pa.

You certainly don't need $100k pa in retirement income unless you want to own a car, travel the world and party all day.

Don't have to work until you die. You may die sooner than you think.

I see many cases of highly stressed executives who die in their 60s. They worked hard their whole life and hardly enjoyed a good retirement. All their wealth go to their children who retire early to enjoy their fortune.
