A government bond that rewards patience
Singapore Savings Bonds are unusual in the bond world: they pay you more the longer you stay. Each issue sets a schedule of coupons that climbs year by year over a ten-year life, so the first year might pay a modest rate while the tenth pays noticeably more. The figure this calculator asks for is the average return over your chosen holding period, which is the single number that captures that climb once you blend the low early coupons with the higher later ones. Hold to year ten and you lock in the full average; bail out in year two and your realised average is closer to the lower opening rungs.
This tool is built for savers comparing where to park money that needs to stay safe: an emergency fund, a property deposit being assembled, a parent's cash that cannot tolerate a drawdown. SSBs are fully backed by the Singapore Government, the interest is tax-free for individuals, and there is no capital gains tax to erode the return on the way out. They are not for chasing yield. They are for sleeping at night.
Fifty thousand dollars held the full ten years
Suppose you place $50,000 and hold for the full decade at an average return of 3 percent. The calculator treats SSB coupons as paid out twice a year rather than compounded, so the arithmetic is principal times average rate times years. That deliberately mirrors how the bond actually pays: cash hits your account every six months, it does not roll up inside the bond.
| Input | Value |
|---|---|
| Amount invested | $50,000 |
| Average return over hold | 3 percent |
| Years held | 10 |
| Interest: $50,000 times 3 percent times 10 | $15,000 |
| Value returned at the end | $65,000 |
The chart sketches the shape of a typical step-up coupon. The early years sit below the average line and the later years rise above it, which is exactly why redeeming early surrenders the best part of the deal.
Liquidity, the $200,000 ceiling, and laddering
The feature that sets SSBs apart from a fixed deposit is that you can redeem in any month with no penalty and get your full principal back, plus any accrued interest. There is no breakage fee and no lost capital, which makes them a genuine emergency reserve rather than money you have tied up. Each person can hold up to $200,000 of SSBs across all issues, so a couple can shelter $400,000 between them.
A practical tactic is to ladder: rather than dumping a lump sum into one issue, subscribe across several months. Because each month's issue carries its own coupon schedule tied to prevailing rates, spreading your entries smooths out the rate you capture and gives you staggered redemption points. The common mistake is treating SSBs like a ten-year lock; in truth they are closer to a flexible savings account with a government guarantee, and the only real cost of redeeming early is the higher coupons you walk away from.
Can I lose money on a Singapore Savings Bond?
No. Your principal is returned in full whenever you redeem, and the interest accrued up to that point is paid out. There is no market price to fall and no penalty for early exit, unlike a tradable bond whose value moves with interest rates. The only thing you forgo by leaving early is the richer coupons scheduled for the later years.
How does an SSB compare with a fixed deposit at the same headline rate?
A fixed deposit usually pays a flat rate and penalises early withdrawal, often clawing back interest. An SSB pays a rising schedule and lets you exit any month with principal intact. If a bank offers a sharply higher one-year promotional rate and you are certain about the lock-in, the fixed deposit can win over a short window. For flexible, multi-year safe money, the SSB's penalty-free exit and tax-free interest usually make it the stronger hold.
