Frequently Asked Questions
What is a fixed deposit?
A Fixed Deposit (FD) is a type of savings product that lets you earn a guaranteed interest rate on a lump sum of money over a fixed period of time.
Offered by banks and financial institutions, it is one of the most straightforward and low-risk ways to grow your savings. FDs are commonly used by individuals looking to preserve capital while earning a predictable return.
You agree to lock in your money for a set period—typically ranging from 1 to 24 months or more—and in return, the bank pays you interest. If you withdraw early, there may be penalties or a reduction in interest earned.
FDs are also insured under the Singapore Deposit Insurance Corporation (SDIC) for up to $100,000 SGD per depositor per bank, adding an extra layer of safety.
How is fixed deposit interest calculated?
Fixed deposit interest is usually calculated using simple interest, meaning you earn interest only on your original deposit. The formula is: Interest = Principal × Rate × Time. Most banks pay FD interest monthly or at maturity, and it doesn’t compound unless specifically stated for multi-year deposits.
In most cases, banks in Singapore use simple interest for FDs. That means your interest is calculated only on the initial deposit, not on accumulated interest.
Formula:
Interest = Principal x Interest Rate x Time
Here are a few examples to illustrate how interest is earned over different tenures:
| Principal | Interest Rate (p.a.) | Tenure | Interest Earned | Maturity Amount |
|---|---|---|---|---|
| $10,000 SGD | 3.20% | 3 months | $80 SGD | $10,080 SGD |
| $10,000 SGD | 3.50% | 6 months | $175 SGD | $10,175 SGD |
| $10,000 SGD | 3.80% | 12 months | $380 SGD | $10,380 SGD |
The maturity amount you see reflects how much you’ll receive at the end of your selected tenure, assuming you don’t withdraw early. While longer tenures often offer higher interest rates, they also reduce liquidity. Be sure to compare rates across banks before committing—especially during promotional campaigns.

What's the difference between simple interest and compound interest?
Simple interest is earned only on your original deposit, while compound interest builds on both your principal and previously earned interest. Over time, compound interest grows your money much faster.
| Feature | Simple Interest | Compound Interest |
|---|---|---|
| What it earns on | Principal only | Principal + accumulated interest |
| Growth speed | Slower, linear | Faster, exponential |
| Common uses | Fixed deposits | StashAway Simple, StashAway Simple Plus |
What is the minimum amount to open a fixed deposit in Singapore?
It depends on the bank, but it's usually more than $500 SGD. Refer to our latest weekly updates on the best Singapore fixed deposit rates.
Can I withdraw my fixed deposit early?
Yes, but doing so may lead to forfeiture of interest and possible penalties.
Are fixed deposit returns guaranteed?
Yes, interest rates are fixed at the time of deposit and insured up to $100,000 SGD per bank under SDIC.
How is fixed deposit interest paid?
Fixed deposits typically payout interest at the end of the tenure also known as at maturity. However, some banks may offer monthly, quarterly or semi-annual payout options for longer tenures.
What’s the best tenure for a fixed deposit?
That depends on your financial goals. Shorter tenures offer more flexibility, while longer ones may offer slightly higher returns.
Are fixed deposits better than savings accounts?
It depends on your strategy as fixed deposits and savings accounts differ.
| Feature | Fixed Deposits (FDs) | Savings Accounts |
|---|---|---|
| Interest Rate | Usually higher, fixed for the entire term | Lower, may vary month to month |
| Flexibility | Low — funds locked in for a set period | High — withdraw anytime |
| Early Withdrawal | Penalties or loss of interest | No penalties |
| Risk Level | Very low, guaranteed rate | Very low, but variable rate |
| Ideal For | Medium-term savings you won’t need immediately | Emergency funds or daily money management |
| Minimum Balance | Often required | Usually low or none |
| Interest Type | Generally simple interest | Often compounded monthly |
