What is an emergency fund?
An emergency fund is a reserved amount of money set aside exclusively for unplanned essential expenses: medical costs, urgent repairs, sudden job loss. It is not a general savings buffer.
How much should be in one?
A common starting target is three months of essential expenses, not income. For people with variable income or fewer safety nets, six months is a more realistic minimum.
Where should the money be kept?
A separate savings account that is not linked to your daily spending card. The friction of a separate account reduces the temptation to dip into it for non-emergencies.
Does it earn interest?
Ideally yes. A high-yield savings account in Singapore such as those offered by DBS Multiplier or OCBC 360 can generate meaningful interest while keeping funds accessible.
When is it acceptable to use it?
Only when the expense is unexpected, necessary, and cannot be covered by current monthly income. A sale on electronics does not qualify. A broken refrigerator does.
Building this fund before addressing other financial goals is not a conservative choice, it is a structural one. Without it, any budget falls apart at the first real disruption.
