How do you determine how much you set aside per month for savings?

I try to save a minimum of 20% of my monthly salary. You should have an emergency fund of at least 6 months of your expenses.

Other than an emergency fund, you should also start to consider your insurance plans. Do you have dependents and also will you be able to pay for your medical bills? You can check out this flowchart on the different insurance policies

Also, would you like to purchase a house in the future? Do you have enough to pay for your down payment with either your CPF or cash? There are also extra charges that you should take into consideration stated in this article.

Furthermore, it is important to consider your retirement. How much do you think you would need to retire? Is CPF LIFE monthly payouts enough?

Track your expenses for a few months - see if you are spending too much on a particular category (food, transport etc) and see where to cut.. when you know where you can cut, then you will know how much you actually can save.

Wait, she spending your money? Red flag

Roughly 20percent of my net salary will go into saving account.
