What Is a Sinking Fund and Do You Need One in Singapore?
You already know a wedding, a home renovation, or yearly insurance renewal is coming, and you have a rough idea of what it will cost. But when the bill actually arrives, it is easy to end up paying for it out of your everyday savings, or worse, your emergency fund.
A sinking fund fixes that. This guide covers what a sinking fund is, how it differs from an emergency fund, how to work out how much to save, and where to keep the money in Singapore.
What Is a Sinking Fund?
The meaning of a sinking fund is simple: it is a specific type of savings fund for an expense you already know is coming. Instead of facing a S$6,000 wedding contribution or renovation deposit all at once, you save towards it in smaller amounts, for example S$500 a month for 12 months. By the time the bill arrives, the money is already there.
Common sinking fund examples in Singapore include:
- BTO or resale flat renovations.
- Wedding banquets and related costs.
- Annual car insurance and road tax.
- Festive spending around Chinese New Year or Christmas.
- Annual holidays or family trips.
In each case, you already know roughly how much you need and roughly when you need it. That is what makes a sinking fund different from saving for the unknown.
Sinking Fund vs Emergency Fund: What's the Difference?
Both a sinking fund and an emergency fund involve setting money aside, but for different purposes.
An emergency fund is for the unexpected: job loss, a medical bill, a burst pipe that needs fixing right away. You don’t know when you’ll need it or how much, so it sits untouched until a real emergency happens.
A sinking fund is for the expected. You know roughly when the expense is coming and how much it will cost, so you save towards that target and spend it in full once the date arrives.
Feature | Emergency Fund | Sinking Fund |
Purpose | Unplanned crises: job loss, medical bills, urgent repairs | Planned expenses with a known cost and date |
Predictability | Unknown timing and amount | Roughly known timing and amount |
How it’s used | Stays untouched until a genuine emergency | Spent in full once the target date arrives |
Typical target | Three to six months of essential expenses | Cost of the specific goal |
If you keep both in one pot, it becomes easy to dip into your emergency money for a planned expense. That leaves you exposed if a real emergency comes along.
How Do You Set Up and Calculate a Sinking Fund in Singapore?
Setting up a sinking fund is simple. Follow four steps:
- List your planned expenses for the next 6 to 24 months, such as a renovation, an insurance renewal, or a friend’s wedding.
- Estimate how much each one will cost, for example S$12,000 for a renovation downpayment.
- Divide the total cost by the number of months you have left. That is your monthly savings target.
- Choose where you want to keep your funds. Keep it separate from your emergency funds and main spending account.
There are a few tips you can follow in order to make it easier to save for a sinking fund.
- Automate the transfer on payday, before the money feels like spare cash.
- Keep each sinking fund for its own purpose. For example, a renovation fund only pays for renovation costs. A wedding fund only pays for the wedding.
- Review your targets regularly every few months to make sure you are on track.
Where Should You Keep Your Sinking Fund in Singapore?
Where you store the sinking fund is also worth looking into. You want three things:
- Safety for your capital.
- A decent interest rate to grow the money while you wait.
- Easy liquidity to access your money when it is needed.
Avoid volatile instruments like stocks or unit trusts. A sinking fund has a fixed deadline, so if the market drops right before you need the cash, you have no time to wait for it to recover.
If your goal does not have a fixed date, you can consider keeping your sinking fund in a fuss-free high interest savings account like SingFinance’s GoSavers Account*. You can earn a competitive 1.30% p.a.** interest on your daily balance, with no salary crediting, no card spend requirement, and no hoops to jump through to unlock higher rates.
