Inputs
Side-by-side at today's rates
Interest earned on your S$10,000 over 1 year.
| Instrument | Rate | Interest | Total at end |
|---|---|---|---|
| Singapore Savings Bond Step-up coupon; held to matching duration | — | S$0 | S$0 |
| 6-month T-bill Roll into a new auction every 6 months at today's yield | — | S$0 | S$0 |
| 1-year T-bill Roll into a new auction every 12 months at today's yield | — | S$0 | S$0 |
| SGS bond Picks the closest tenor to your hold duration; coupon rate, held to maturity | — | S$0 | S$0 |
| CPF Ordinary Account 2.5% base rate only — does not add CPF's extra 1% on the first S$20,000 or the age-55+ bonus | 2.50% | S$0 | S$0 |
Totals are simple-interest estimates (rate × years × principal). Actual returns may be higher if you reinvest payouts, or lower if a future T-bill auction prices below today's cutoff. The CPF figure uses the 2.5% base rate only — it does not add the extra interest bonuses on the first S$60,000 combined balance (+1% for members under 55, or +2% on the first S$30K and +1% on the next S$30K for members aged 55 and above), nor the S$20,000 OA contribution cap on those bonuses.
Method notes
Formula. Interest = principal × rate × years. All four rows use the same method so you can compare them directly.
SSB rate. We use MAS's published per-year effective return from the latest issue: the year-1 rate for holds up to 1 year, year-5 rate at 5 years, and so on. These are the same numbers MAS shows on its product page.
T-bill rolling. A single auction only lasts 6 or 12 months. For longer durations we assume you buy the next auction at today's cutoff yield — which is a "what if rates stay here" scenario. Actual future yields will differ.
SGS bonds. SGS comes in 2/5/7/10/15/20/30/50-year tenors. We snap your hold duration to the closest available tenor and use that issue's fixed coupon rate as the rate. The total assumes you hold to maturity (coupons paid out, not reinvested) and SGS returns face value. If you sell before maturity, you're exposed to market-price risk — the bond's price moves inversely to rates and can be above or below face value. That risk is not modelled here.
CPF-OA. Uses the 2.5% base rate per the CPF Board interest-rate page, simple interest to match the others. CPF also pays an extra 1% per annum on the first S$20,000 in OA (combined across OA/SA/MA/RA up to S$60,000), and an extra 2% on the first S$30,000 for members aged 55 and above. Those bonuses are not included in the figure above — if they apply to you, your real CPF-OA return will be higher.
Not included: S$2 transaction fee on SSB applications and redemptions; brokerage fees for buying SGS bonds on SGX or through CDP; any secondary-market price change if you sell SGS before maturity; CPFIS charges if buying through CPF.
