SSB Interest Calculator — Latest Issue (SBAUG26, Aug 2026)
Understanding the SSB Step-Up Structure for Singapore Investors
A Singapore Savings Bond (SSB) is a 10-year government security issued monthly by the Monetary Authority of Singapore (MAS) and fully backed by the Singapore Government. Unlike a fixed deposit, an SSB pays step-up interest — the coupon rate rises every year you hold it, from a modest Year 1 rate to a higher Year 10 rate, rewarding patience while still letting you redeem in any month without capital loss. Coupon rates for each monthly tranche are pegged to the prevailing Singapore Government Securities (SGS) yield curve, so no two issues pay exactly the same schedule. This calculator uses the live rates for the SBAUG26 (August 2026) tranche — the issue open for application until 28 July 2026 — so you can see exactly how much interest S$500 to S$200,000 would earn if held for anywhere from one to ten years.

Why the August 2026 Issue Matters
The SBAUG26 tranche (ISIN code GX26080T) offers a 10-year average return of 2.06% p.a. if held to maturity — a step down from July's 2.11% and a reminder that SSB rates move with the broader SGS yield curve rather than a fixed schedule. Its Year 1 rate of 1.46% p.a. is actually lower than the 1.55% cut-off yield at the 16 July 2026 six-month T-bill auction, so investors parking cash for only a year or two may find T-bills or fixed deposits more competitive right now. The trade-off is exactly what SSBs are built for: hold past Year 5 and the coupon accelerates past 1.90%, reaching 2.72% by Year 10 — a structure this calculator lets you model precisely instead of estimating.
How MAS Sets the Coupon Schedule
MAS calibrates each SSB issue so the average compounded return over any given holding period tracks the SGS bond yield of a matching tenor — the 1-year, 2-year, 5-year and 10-year benchmarks from the month before the issue is announced. If the SGS yield curve is flat or inverted, MAS may adjust individual years so interest never steps down, though this doesn't change the 10-year total. Small rounding differences of up to ±0.03% can also appear in the published averages. Because the schedule is locked in on the day you apply, redeeming early always means accepting the average return only up to that point — never the full 10-year figure.

What Is a Singapore Savings Bond (SSB)?
A Singapore Savings Bond is a type of Singapore Government Security (SGS) created specifically for individual investors, first launched in 2015. Every SSB has a 10-year tenor and is backed by the full faith and credit of the Singapore Government, making it one of the lowest-risk instruments available to retail investors in Singapore — the same credit standing as SGS bonds and Treasury bills.
What sets an SSB apart from a regular bond is its step-up interest structure and redemption flexibility. Coupon interest is paid every six months, and the rate increases each year you continue holding the bond. Unlike most bonds, you never need to sell an SSB on the open market to exit early — you simply submit a redemption request to MAS through your bank in any month before maturity, opening at 6pm on the 1st business day and closing at 9pm on the 4th-last business day of the month, and receive your full principal back with no capital loss, less a small S$2 transaction fee.
A new SSB tranche is issued every month, each with its own coupon schedule set independently based on prevailing SGS yields. You can invest from as little as S$500, in multiples of S$500, up to an individual lifetime cap of S$200,000 across all SSB holdings (cash and SRS combined). For the August 2026 issue (SBAUG26, GX26080T), applications close 28 July 2026, 9pm, with allotment announced shortly after.
How the SBAUG26 Step-Up Rate Works: Year-by-Year Breakdown
Every SSB tranche publishes two figures per year: the actual interest rate paid that year, and the cumulative average annual compounded return an investor earns if they redeem at the end of that year. The gap between the two numbers is the whole story — the interest rate is what you're paid that specific year, while the average return is what your money has effectively earned since you first bought in, compounded.
| Year | Interest Rate % | Avg Return %* |
|---|---|---|
| 1 | 1.46 | 1.46 |
| 2 | 1.75 | 1.60 |
| 3 | 1.80 | 1.67 |
| 4 | 1.80 | 1.70 |
| 5 | 1.90 | 1.74 |
| 6 | 2.11 | 1.80 |
| 7 | 2.27 | 1.86 |
| 8 | 2.43 | 1.93 |
| 9 | 2.58 | 1.99 |
| 10 | 2.72 | 2.06 |

Redeem after Year 1 and you lock in exactly 1.46% — no better, no worse. Hold to Year 5 and your money has compounded at an average 1.74% p.a., even though the Year 5 coupon itself is 1.90%, because the earlier low-rate years still drag the average down. Only by holding the full 10 years do you capture the advertised 2.06% p.a. headline rate, once the Year 10 coupon has climbed to 2.72%. This is the single most misunderstood part of SSB investing: the number printed in every news headline is a 10-year-only figure. Redeem in Year 3 expecting anything close to it and you'll be disappointed with 1.67% instead — use the calculator above to plug in your own expected holding period rather than relying on the headline rate alone.
SSB vs T-Bills vs Fixed Deposits in Singapore 2026
All three are considered "safe" parking spots for Singapore dollars, but they behave very differently once you factor in lock-up and flexibility. The table below compares the SBAUG26 SSB against the most recent 6-month T-bill auction and a typical current bank fixed deposit promotion.
| Feature | SSB (SBAUG26) | 6-Mth T-Bill | Bank FD Promo |
|---|---|---|---|
| Yield | 1.46% (Yr1) – 2.06% (10yr avg) | 1.55% (16 Jul 2026 auction) | ~1.0% – 1.68% p.a. |
| Tenor | 10 years (flexible exit) | 6 months (fixed) | 6–12 months typical |
| Early exit | Any month, no capital loss | Sell on SGX at market price | Often forfeits promo rate |
| Min investment | S$500 | S$1,000 | S$1,000–S$20,000 |
| Backing | Singapore Government | Singapore Government | SDIC insured to S$100k |
Right now, a 6-month T-bill's 1.55% actually beats the SSB's own Year 1 rate of 1.46%, and CPF Ordinary Account pays a flat 2.50% with no market risk at all — so SSB rarely wins on short-horizon yield alone. Its edge is structural: no reinvestment risk for a full decade, monthly redemption flexibility with zero capital loss, and a rate that keeps climbing the longer you're willing to wait. Run your own numbers through our T-Bill, SSB & Fixed Deposit Comparison Calculator before deciding where to park new cash.
How to Buy Singapore Savings Bonds in Singapore
Buying an SSB is entirely digital. You'll need an individual CDP Securities account first, since that's where your bond holdings are recorded. Once that's set up, applications go through the internet banking portal or ATM of any of the three participating banks — DBS/POSB, OCBC, or UOB — under the Singapore Government Securities section. Applications open at 6pm on the 1st business day of the month and close at 9pm on the 4th-last business day; a non-refundable S$2 fee applies per application, and allotment is confirmed a few business days later.
SSBs aren't the only place to park spare cash while you wait for the next attractive issue, or to diversify beyond a single 10-year lock-in structure. If you're building a broader passive-income portfolio alongside your SSB allocation, robo-advisors and brokerages such as Endowus, Syfe, and FSMOne all offer cash management or T-bill/bond-laddering options that can complement an SSB core holding, each with different fee structures worth comparing before you commit new capital.
Can You Use CPF or SRS to Buy SSB?
No — CPF savings (Ordinary, Special, or MediSave Account funds) cannot be used to buy Singapore Savings Bonds. This surprises many first-time investors, since CPF funds under the CPF Investment Scheme (CPFIS) can be used to buy other Singapore Government Securities, including T-bills and SGS bonds. SSBs were deliberately excluded from CPFIS because they're designed as a cash-savings alternative for money you'd otherwise leave in a bank account — and CPF Ordinary Account already pays a guaranteed 2.50% (with Special/MediSave/Retirement Account funds earning up to 4.00% under the current floor extended to 31 December 2026), which typically outperforms the early years of an SSB's step-up schedule anyway.
Supplementary Retirement Scheme (SRS) funds, on the other hand, can be used to buy SSBs. You apply through your SRS operator's (DBS, OCBC, or UOB) internet banking portal rather than a regular bank account, and the same S$500 minimum and S$200,000 individual cap apply, combined across your cash and SRS SSB holdings. Because SRS contributions already enjoy dollar-for-dollar tax relief, using idle SRS cash to buy a government-backed SSB rather than leaving it earning close to 0% in the SRS account is one of the simplest ways to put idle SRS balances to work. If you're weighing this trade-off, our SRS Tax Savings Calculator and CPF OA/SA Allocation Calculator can help you see the fuller picture.
SSB as Part of a Retirement Passive Income Strategy
SSBs aren't built to be a portfolio's growth engine — they're the ballast. In a typical Singapore retirement bucket strategy, SSBs and T-bills sit in the "safety" bucket alongside CPF LIFE and fixed deposits, providing capital you can access without selling equities or S-REITs during a downturn. Because SSB interest steps up the longer you hold, laddering several tranches bought across different months (rather than one lump sum) smooths out your average entry rate and staggers your redemption flexibility, so you're never fully locked into a single month's rate.
For investors closer to retirement, the appeal is simple: predictable, government-backed cash flow that complements higher-yielding but more volatile S-REITs and dividend stocks. A common allocation is to size the "safe" bucket (SSB, T-bills, CPF LIFE) to cover several years of expected withdrawals, freeing the rest of the portfolio to stay invested for growth. Use our Retirement Planning Calculator to model how much of your portfolio should sit in safe instruments like SSB, and see our Passive Income Guide for how SSBs fit alongside dividend-paying S-REITs in a full retirement income plan.
Frequently Asked Questions
Is this SSB calculator based on the current August 2026 rates?
Yes. The default rates in this calculator are the official published coupon schedule for SBAUG26 (GX26080T), the SSB tranche open for application until 28 July 2026, offering a 10-year average return of 2.06% p.a. if held to maturity. If you're planning around a future issue, toggle "Use custom rates" to model a different schedule.
What is a good 10-year average return for an SSB in Singapore?
Over the past decade, SSB 10-year average returns have ranged from below 0.5% (2020–2021) to above 3% (2023–2024), so "good" is relative to when you're buying. At 2.06% p.a., the SBAUG26 issue sits toward the lower half of that range, but it remains higher than most bank savings accounts' base rates and is fully government-backed.
Is SSB a good investment in Singapore right now?
It depends on your time horizon and what else you'd do with the cash. If you need liquidity within a year or two, a 6-month T-bill currently yields 1.55%, higher than the SSB's own Year 1 rate of 1.46%. If you're comfortable locking funds away with the option to exit penalty-free, the step-up structure rewards patience and can outperform rolling T-bills in later years.
How much interest will I earn if I invest S$10,000 in SSB for 5 years?
Based on the SBAUG26 schedule, S$10,000 held for exactly 5 years earns S$871 in total interest (1.46% + 1.75% + 1.80% + 1.80% + 1.90% of your principal, paid out over the period), for an effective average annual return of 1.74% p.a. Enter your own amount and holding period into the calculator above for an instant breakdown.
What is the difference between SSB and T-bills in Singapore?
T-bills are short-term (6-month or 1-year) securities sold at a discount with a fixed yield locked in for that period, and you'd need to sell on the SGX secondary market to exit early, potentially at a loss. SSBs run for 10 years with a step-up coupon and can be redeemed penalty-free (aside from a S$2 fee) in any month, making them more flexible but generally lower-yielding in the short term.
How much of my savings should I put into SSB in Singapore?
There's no universal number, but many Singapore investors treat SSB as part of a broader "safe" allocation — typically sized to cover several months to a few years of expenses — alongside CPF, T-bills, and fixed deposits, rather than as a primary growth holding. The S$200,000 individual cap also naturally limits how much of a portfolio SSB can represent for larger investors.
Which Singapore bank is best for buying SSB?
DBS/POSB, OCBC, and UOB all offer identical SSB applications with the same S$500 minimum, S$2 fee, and allotment process, since applications are ultimately processed by MAS regardless of which bank you use. The "best" bank is simply whichever you already bank with, since there's no rate or fee difference between them for SSB specifically.
Can I use SRS to buy Singapore Savings Bonds?
Yes. SRS (Supplementary Retirement Scheme) funds can be used to buy SSBs through your SRS operator's internet banking portal, subject to the same S$500 minimum and S$200,000 individual cap (combined across cash and SRS holdings). CPF savings, however, cannot be used to buy SSBs under any circumstances.
How does SSB interest rate affect my retirement planning in Singapore?
SSBs function as a low-risk, government-backed anchor within a retirement portfolio's "safe" bucket, providing predictable cash flow that doesn't require selling equities or REITs during a market downturn. The step-up structure also makes SSB laddering — buying different tranches across several months — a useful way to build a maturing income stream that complements CPF LIFE payouts and dividend income in later retirement years.
