Return calculator

Estimate how much you'd earn on a Singapore Savings Bond or Treasury Bill at current rates. Informational only — not financial advice.

Inputs

SSB min S$500 (multiples of S$500). T-bill min S$1,000 (multiples of S$1,000).

For T-bills, held to maturity only. For SSB, any whole or half year up to 10.

Calculations assume simple annualized return at the quoted rate. Real returns may differ due to compounding, fees, market yield changes (for T-bills sold early), and step-up effects (for SSB held multiple years). See the method notes below.

Method notes

T-bills: we use principal × cutoff_yield × (days / 365) where days = 182 for 6-month or 364 for 1-year. This matches the discount pricing MAS uses for a single auction held to maturity.

SSB year 1: we use the year-1 coupon rate. For durations under 1 year, return = rate × years.

SSB multi-year: we approximate with the 10-year average rate weighted against the duration. For durations less than 10 years, the real return is lower than this approximation (the step-up curve loads the higher rates toward later years). For a more precise figure, look at the specific issue's coupon schedule.

Not included: the S$2 transaction fee on SSB applications and redemptions; any early-redemption market-price effect on T-bills; CPF-related charges if buying through CPFIS.
