Worked example
Suppose you place HK$300,000 into a 12 month time deposit at a 3.5 percent annual rate. The interest is HK$300,000 times 3.5 percent times one year, which is HK$10,500. Hong Kong does not tax interest earned by individuals on a bank time deposit, so the full HK$10,500 is yours and the maturity value is HK$310,500. A shorter tenor is pro-rated, so the same deposit over six months would pay HK$5,250. The rate is fixed for the agreed term, which is the trade-off for locking the money away. Breaking a time deposit early usually means forfeiting some or all of the interest, so only commit funds you will not need before maturity.
How it is calculated
The tool computes simple interest on the principal for the term you choose: principal times the annual rate, pro-rated by the number of months over twelve. The maturity value is the principal plus that interest. Because Hong Kong has no interest or savings tax for individuals, the interest is received in full and the tax line is zero. This matches how a standard fixed-term deposit is quoted, where the bank states an annual rate for a set tenor. The figure assumes interest is paid at maturity rather than compounded during the term, which is the usual structure for a single time deposit. For a rolling deposit that reinvests interest each period, the compounding tool gives the higher effective return.
