-
Step 5: Redeem when you want to
Between the 1st business day and the 4th last business day of a monthProceeds arrive by the 2nd business day of the next month. A bond that matures is redeemed automatically.
How a Savings Bond works
A Singapore Savings Bond (SSB) is a government bond for individuals. You invest from $500, hold it for up to 10 years, and can redeem in any month without penalty. The interest rises the longer you hold it, which is why it is called a step-up bond.
Coupon and average return
Each issue has two sets of numbers:
- Coupon: the interest rate for each year you hold the bond.
- Average annual return: the compounded average over the years you have held it, which is the number to compare with other savings.
The November 2026 issue (SBNOV26, code GX26110X) is the sample used by the calculator:
| Year held | Coupon | Average return if held to end of year |
|---|---|---|
| 1 | 1.67% | 1.67% |
| 2 | 2.00% | 1.83% |
| 3 | 2.19% | 1.95% |
| 4 | 2.35% | 2.05% |
| 5 | 2.49% | 2.13% |
| 6 | 2.61% | 2.21% |
| 7 | 2.70% | 2.27% |
| 8 | 2.79% | 2.33% |
| 9 | 2.91% | 2.39% |
| 10 | 3.08% | 2.45% |
How much interest you earn
Interest for each year is the principal times that year's coupon. For $10,000:
| Held for | Total interest | Total received | Average return |
|---|---|---|---|
| 1 year | $167 | $10,167 | 1.67% |
| 5 years | $1,070 | $11,070 | 2.13% |
| 10 years | $2,479 | $12,479 | 2.45% |
Interest is paid every six months and is not reinvested into the bond, so the cash totals above are the simple sum of the yearly coupons. The average return is a compounded measure, which is why it is not the same as total interest ÷ principal ÷ years.
Limits
- Minimum: $500, in multiples of $500.
- Holdings limit: $200,000 across all the Savings Bonds one person holds, not per issue.
- Only individuals can apply. You can use cash or SRS money.
When you can apply and redeem
| Action | Window |
|---|---|
| Apply for the new issue | From 6.00 pm on the 1st business day of the month to 9.00 pm on the 4th last business day |
| Redeem a bond | From the 1st business day to the 4th last business day |
| Receive redemption proceeds | By the 2nd business day of the next month |
Tip: Savings Bonds are not for money you need this week, because redemption proceeds arrive only in the following month. Keep an emergency fund in an account you can use immediately.
Common mistakes
- Treating $200,000 as a per-issue cap. It is a total holdings limit.
- Comparing the year-1 coupon with other rates. Compare average returns for the period you will hold.
- Using last month's issue. Each month has new rates. Paste the current coupons into the calculator.
- Expecting same-day cash. Redemption takes until the next month.
- Assuming interest compounds in the bond. It is paid out every six months.

Frequently asked questions
What is the 10-year average return for SBNOV26?
2.45% p.a. if held 10 years. Year-1 coupon is 1.67%. $10,000 held 10 years receives $2,479 of interest.
Do I lose money if I redeem early?
No. MAS returns principal plus accrued interest. You simply miss later step-up coupons.
Is interest compounded inside the bond?
No. Coupons are paid out every six months. The average-return column is a MAS compound average of the coupon path, not automatic reinvestment.
What is the minimum investment?
$500, in multiples of $500, up to $200,000 in total across all Savings Bonds you hold (the individual holdings limit).
Can I model a future issue?
Yes. Paste ten coupon percentages from the MAS announcement. Averages are then estimated geometrically.
Is this the same as the compound-interest calculator?
No. That tool is a generic compounding formula. This one uses SSB coupon tables and MAS hold-period averages.
When is interest paid?
Every six months on the issue’s payment dates (for SBNOV26, 1 May and 1 November).
Is this MAS advice?
No. Confirm on the Singapore Savings Bonds website. Coupons can differ each month.
