I am retiring when I reach 55 after collecting my CPF. I will be getting about $200k from my CPF OA. Since my home is paid up, I just need $20k per year to last me from age 55 to 65. My CPF Life will give me $2k per month at age 65.

Food and groceries $500 pm
Public transport $50 pm
Phone $50 pm
Utilities $100 pm
Insurance $300 pm
Miscellaneous $100 pm
Total $1100 pm or $13,200 pa or $132k over 10 years
