Singapore Savings Bonds Calculator
Project interest and MAS average returns if you hold a Singapore Savings Bond for 1–10 years. Defaults to SBOCT26 (GX26100Z); paste another issue’s coupon schedule if you prefer.
Minimum $500, in multiples of $500, up to $200,000 per issue.
You may redeem any month without penalty. Average return and total interest assume you hold whole years.

Hold-period estimate
SSB pays interest every six months. Coupons are not automatically reinvested in the bond. MAS average returns are compounded averages linked to SGS yields (small rounding differences of up to 0.03% can appear). Not investment advice.

About this Singapore Savings Bonds calculator
Singapore Savings Bonds are MAS-issued, individual-only bonds you can buy through DBS, OCBC or UOB (or SRS). You start with as little as $500, earn a step-up coupon for up to 10 years, and can exit in any month without capital loss.
This page defaults to SBOCT26 (GX26100Z), issued 1 October 2026. Year-1 coupon is 1.65%, year-10 is 3.01%, and the published 10-year average return is 2.32%. Holding $10,000 for 10 years pays $2,348 of cash interest (the sum of the annual coupons), then returns the $10,000 principal.
Interest is credited every six months. The “average return” column is MAS’s compound average if you hold for that many years — it is not the simple average of coupons, and it is not a promise that coupons are reinvested. Paste another issue’s 10 coupons to remodel; the page then estimates averages geometrically (MAS may differ by up to 0.03% from rounding).
Applications close on the fourth-last business day of the month. Allotment can be pro-rated when an issue is oversubscribed. This is not a live MAS feed.

Frequently asked questions
What is the 10-year average return for SBOCT26?
2.32% p.a. if held 10 years. Year-1 coupon is 1.65%. $10,000 held 10 years receives $2,348 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 per issue (subject to the individual aggregate cap MAS publishes).
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 SBOCT26, 1 April and 1 October).
Is this MAS advice?
No. Confirm on the Singapore Savings Bonds website. Coupons can differ each month.
