Compound interest pays interest on your interest. The longer you leave it, the faster it grows: at 5% a year money doubles in about 14 years (the rule of 72: 72 ÷ rate). Interest from approved bank deposits is tax-free for individuals in Singapore.
Interest before tax and fees, at the same rate every year; monthly additions are made at the end of each month. Not legal, tax or financial advice. 🔒 Everything stays on your device.

Questions people ask
How is compound interest calculated?+
Balance = amount × (1 + rate ÷ n)^(n × years), where n is how often interest is added. Monthly savings are added on top and earn interest too.
How long does it take to double my money?+
Divide 72 by the yearly rate: at 6% about 12 years, at 4% about 18 years.
Does compounding frequency matter much?+
A little: 3% compounded monthly is 3.04% a year. Regular saving and time matter much more.
