I've been working for 2 years and have been consistently saving up. I am a financial adviser myself hence I always try to advise my clients to try to do the same.
As a self-employed, my salary is not fixed and I do not contribute to my CPF.
For this purpose, I will take my salary to be about $4k.
In this instance, I lose out to all employed persons out there because I have to set aside 17% on top of the 20% which your boss will pay to you.
"CPF" = $1480 (37%)
I save this amount in OCBC 360 which will generate higher interest for me because I could fulfill some of the criteria. This is the account that my salary is credited into.
I am left with $2520. I will try to save 30-40%, hence $1008.
Savings = $1008 (40%)
$2520 - $1008 = $1512
Insurance = $300
Mother allowance = $250
Transport = $100
Tax = $100
Entertainment/Food = $762
I also will slowly save up to set aside for an emergency fund. It will be about 4-6 months of your monthly expenses, in case of unforeseen circumstances like retrenchment and when your friends start to throw wedding bombs at you.
On top of that, I will attend focus group and surveys to make extra cash. I hope it helps!!!
Remember the ultimate rule:
Pay yourself first before you pay others.
