Whether SGD $10,000 is a sufficient amount for an emergency fund in Singapore depends on your personal circumstances, specifically your monthly living expenses.
If your monthly expenses total SGD $2,000, for example, an SGD $10,000 emergency fund would cover about 5 months of living expenses. This would be considered a solid emergency fund. However, if your monthly expenses are higher, say SGD $3,500, an SGD $10,000 emergency fund would only cover about 3 months of expenses.
