About CalcIsland

CalcIsland is a free website of personal-finance calculators, written in English and Traditional Chinese (Hong Kong usage).

The tools cover general questions, including US investing basics such as compound growth, and Hong Kong topics such as mortgages, salaries tax, and MPF.

You do not need an account. Each calculator runs in your browser and shows the formula it uses.

The figures are for learning. They are not financial, investment, or tax advice. Read the disclaimer before you rely on a number.
