Quick Answer
MoneySense gives three to six months of expenses as a starting point. Your target depends on how steady your income is, who depends on you and how long replacing income might take. A six-month target would be S$18,000, leaving S$9,000 still to save.
The Useful Number: S$9,000 covers three months of S$3,000 essential spending. A six-month target would be S$18,000.
How Do You Work Out Your Costs And Target?
An emergency fund is cash for shocks, like lost income or an urgent essential cost. List what you would still pay if your income stopped: housing, groceries, utilities, transport, insurance and minimum debt payments.

What Does A Six-Month Buffer Look Like?
Say essential spending is S$3,000 a month and you have S$9,000 of emergency cash. That covers 3 months. A six-month target is S$18,000, so S$9,000 is still needed: about 9 months at S$1,000 a month.
That assumes no withdrawals and the same amount saved each month, with interest and inflation left out. If saving that much leaves you short for current bills, change the amount or the target.
- Today: S$9,000 Saved: Covers 3 months (S$9,000 ÷ S$3,000).
- Add S$1,000 Each Month: S$9,000 still needed, so about 9 months.
- Target: S$18,000: Six months of essential spending (S$3,000 × 6).

What Money Should Count Towards Your Emergency Fund?
Do not count the same savings as both a house deposit and an emergency fund. Leave credit limits, CPF and investments out. They have different rules on when you can use them, or you may have to borrow or sell at a bad time.
Before choosing where to keep it, check how fast you can get the money, the withdrawal conditions and any charges. A high advertised return does not mean the money will be there when an urgent bill arrives.
How Do You Keep Your Buffer Up To Date?
Recalculate after a move, a new dependant, a change in income or using the buffer. Budget for predictable costs, such as a yearly renewal, separately. The Monthly Savings Split helps you find a monthly amount that fits.

Card 1 Of 3
MoneySense gives three to six months of expenses as a starting point.
Why? Card 1 Of 3
Your own target depends on how steady your income is, who depends on you and how long replacing lost income might take.
Card 2 Of 3
CPF savings and investments should count towards your emergency cash.
Why? Card 2 Of 3
You may not be able to reach CPF, and you may have to sell investments at a bad time. Leave them, and credit limits, out of the cash figure.
Card 3 Of 3
With S$9,000 still to save, putting aside S$1,000 a month takes about nine months.
Why? Card 3 Of 3
The estimate assumes the same amount every month and no withdrawals. It leaves out interest and inflation, so do not treat the date as fixed.

What Expenses Should An Emergency Fund Cover?
List the spending you would still need to cover if your income stopped.
Include housing, groceries, utilities, basic transport, insurance and minimum debt payments. Keep predictable costs, such as a yearly renewal, apart from unexpected ones. Budget for them over the year.
How Long Will It Take To Build My Emergency Fund?
In the worked example, you still need S$9,000 to reach an S$18,000 six-month target.
At S$1,000 saved each month, that takes nine months. This assumes no withdrawals and the same amount each month. Interest and inflation are left out. If saving that much leaves you short for current bills, change the amount or the target.
Should CPF Or Investments Count Towards My Emergency Fund?
The calculator leaves credit limits, CPF and investments out of the cash figure.
Those have different rules on when you can use them, or you may have to borrow or sell at a bad time. The guide also warns against counting the same savings as both a house deposit and an emergency fund.
