Calculate the interest earned and maturity value of a Singapore dollar fixed deposit.
A fixed deposit locks your money for a set tenure at an agreed interest rate. Interest is computed as principal × annual rate × (months ÷ 12). For example, S$50,000 at 3.0% p.a. for 12 months earns S$1,500; for 6 months it earns S$750.
Rates vary by bank, tenure and amount, and promotional rates usually need fresh funds and a minimum sum. Withdrawing early typically means losing some or all interest. For individuals, Singapore does not tax bank deposit interest, so the interest shown is what you keep.
